Payroll Tax

What it is, every rate, who pays what, when the money is due, and why the most compassionate decision you can make is the one that costs you your house

Most guides to payroll tax give you a table of rates and stop. The rates are the easy part. Your payroll provider knows them, applies them automatically, and you will never think about them again.

What will hurt you is the deposits. Not the rates, not the forms, not the arithmetic. The money, and when it has to leave your account, and what happens when it does not.

Because here is the situation that ends small businesses, and it does not feel like a mistake when you are in it. Cash is short. You have enough to pay your people or enough to make the tax deposit, not both. Your team has rent to pay. The IRS is an institution. So you pay your people, and you intend to catch up next month, and that decision feels like the decent one because it is.

The IRS has a settled position on that decision. It is willful failure. Your employee, in the government's view, is merely another creditor, and preferring them over the United States is the willfulness. You had a duty to prorate: pay everyone less and make the deposit. And the penalty for getting it wrong is personal, reaches you after the company is gone, and is not dischargeable in bankruptcy.

So this guide covers all of it, at length, for a US business with five to fifty people. Every rate, who pays what, what a hire actually costs, the deposit schedules, the penalties, the forms, the state layer, and the things that pierce your LLC. FirstHR is not a payroll processor and does not calculate or deposit your taxes; a provider does that and you should use one. This is general information rather than tax advice, rates change annually, and this is one of the few areas where the cost of being wrong is genuinely unbounded.

TL;DR
Payroll taxes fund Social Security, Medicare, and unemployment. The employee pays 7.65 percent FICA and you match it, plus you pay FUTA and SUTA alone. Total employer cost: roughly 8 to 11 percent above salary. But the rates are not the risk. The deposits are. Your deposit schedule is assigned to you based on a lookback period, penalties escalate from 2 to 15 percent by the day, and the withheld portion is a trust fund tax. Fail to remit it and a responsible person can be held personally liable for 100 percent of it. And per the IRS, paying your staff instead of the deposit when you cannot do both is itself willful.

What Payroll Tax Is

Taxes on wages, levied at flat rates, to fund specific programs.

Definition
Payroll Tax
Payroll taxes are taxes levied on wages to fund specific social insurance programs. In the US they comprise FICA, which is Social Security and Medicare, and unemployment taxes, being FUTA federally and SUTA at state level. FICA is shared: the employee pays 6.2 percent for Social Security and 1.45 percent for Medicare, and the employer matches both. Unemployment taxes are paid almost entirely by the employer. Federal income tax withholding is administered through the same forms and deposits but is paid entirely by the employee. The IRS uses the umbrella term employment taxes for all of it.

Three properties define them and each has a consequence.

Flat. Social Security is 6.2 percent whether someone earns $30,000 or $150,000. No brackets, no personal circumstances. The only nonlinearities are the wage base, which is a ceiling, and the Additional Medicare Tax, which is a surcharge. It is one of the few genuinely predictable parts of small business HR.

Earmarked. The money funds named programs rather than general spending. Social Security tax funds Social Security. This is why they exist as separate lines rather than being folded into income tax, and why they are sometimes called contributions.

Shared. The property that costs you money. When your employee pays $100 in Social Security, you pay another $100, out of business funds, and it never appears on their pay stub.

Who Pays What

The question underneath every other question in this article.

TaxEmployee paysEmployer paysNotes
Social Security6.2%6.2%Both stop at the annual wage base
Medicare1.45%1.45%No cap. Every dollar, forever
Additional Medicare0.9%NothingAbove $200,000. You withhold it and do not match it
Federal income taxEverythingNothingYou are a courier. Not a cent of it is yours
FUTANothingEverything0.6% effective. About $42 per employee per year
SUTANothing, in most statesEverythingA handful of states require an employee contribution
State income taxEverythingNothingSame as federal. You withhold and remit

Look at the Employer pays column. Where it says Nothing, you are administering somebody else's money. Where it has a number, that money is leaving your account and not coming back. Whether a given worker is exempt or nonexempt does not change any of this, which is a separate question covered in the exempt versus non-exempt guide.

That distinction, between what you pay and what you merely handle, is developed at length in the guide to payroll tax versus income tax. It also turns out to be the thing that makes the trust fund penalty so dangerous, for reasons that become clear later.

Every Rate, in One Table

The complete picture. Verify the current figures each year; the structure holds, the numbers move.

Rates and wage bases are adjusted annually, so verify the current figures against IRS Publication 15 rather than trusting any article, including this one. The structure does not change. Only the numbers do.

Per IRS Publication 15, the Employer's Tax Guide, these are the rates you actually apply. The Social Security wage base rises most years, so a figure printed in an article is a figure that will be wrong.

Two rows in that table are structurally odd and each gets its own treatment below. Additional Medicare is a payroll tax with no employer share, which makes it behave like an income tax in a payroll tax's clothing. And SUTA is the only employment tax whose rate is specific to you rather than set by statute. Both show up as lines on the pay stub, where your employee will notice them and ask.

FICA in Detail

Where most of the money is, and where the employer match lives.

Social Security (OASDI)Medicare (HI)
Employee rate6.2%1.45%
Employer rate6.2%1.45%
Combined12.4%2.9%
Wage capYes. An annual wage base, rising most yearsNone
What happens at the capBoth sides stop for the rest of the yearNothing. It continues on every dollar
FundsRetirement, disability, survivorsHospital insurance

The employee's combined FICA is 7.65 percent. Yours is the same 7.65 percent, out of your own funds. Together, 15.3 percent of every dollar of wages goes to FICA.

The wage base, and the autumn surprise

Social Security stops at the annual wage base. Once an employee's year-to-date wages cross it, the deduction vanishes from their stub and their net pay jumps.

Two consequences, and the second one is the useful one. First, they will come and ask you about it, having concluded that payroll made an error in their favour. Second, your matching contribution stops at exactly the same moment, so your cost for that person falls for the rest of the year and resets in January.

If you employ several people near the wage base, that makes your payroll tax expense genuinely lumpy across the year, front-loaded and then tapering. Worth modelling rather than discovering, alongside the rest of what a person costs you in the guide to how much benefits cost per employee.

The Additional Medicare Tax

An employer must withhold an additional 0.9 percent on wages paid to an employee above $200,000 in a calendar year, beginning in the pay period the threshold is crossed and continuing to year end.

And there is no employer match. You withhold it and you do not pay it, which makes it the only item on the payroll tax list that behaves this way.

The wrinkle: you withhold based on the wages you paid, at $200,000, without regard to filing status. But the employee's actual liability depends on their household situation, so they may end up owing more or less than you withheld. Both are resolved on their return, and neither is your problem once you have withheld correctly.

FUTA and SUTA, the Taxes You Pay Alone

Nothing is withheld from the employee, in almost every state. The whole thing is yours.

FUTA

Per IRS Topic 759, the statutory FUTA rate is 6.0 percent on the first $7,000 of each employee's wages. Employers who pay their state unemployment tax in full and on time receive a credit of up to 5.4 percent, dropping the effective rate to 0.6 percent.

FigureWhat it means
Statutory rate6.0%What you would pay with no state credit
Maximum credit5.4%Earned by paying SUTA in full and on time
Effective rate0.6%What almost every employer actually pays
Wage baseFirst $7,000 per employeeIt stops there. It does not scale with salary
Cost per employeeAbout $42 a yearWhich is why nobody remembers it exists
Deposit triggerQuarterly, once liability exceeds $500Otherwise it rolls into the next quarter
Reported onForm 940, annuallyDue January 31

Forty-two dollars a year per employee. Trivial, and the reason to know about it is the exception.

Credit Reduction States Cost You More
If your state has borrowed from the federal unemployment fund and not repaid it, it becomes a credit reduction state: the 5.4 percent credit is reduced and your effective FUTA rate rises, further for each additional year the loan is outstanding. California has been in this position, and employers there have paid meaningfully above the 0.6 percent baseline as a result. The list is determined annually and lands on the Form 940 you file the following January, which means your FUTA bill can increase without anything about your business changing.

SUTA

State unemployment tax, and it is the strange one, because your rate is personal to you.

States assign an experience rating based on your history of unemployment claims. Lay people off, they claim benefits, your rate goes up. Do not, and it drifts down. New employers start at a standard rate until they have a history to be rated on.

Which produces a fact worth internalizing: firing people is more expensive than it looks, and the extra cost is spread invisibly across your SUTA rate for years afterwards. It is the only tax in this entire article that responds to how you actually run the business, and it belongs alongside the other costs of a departure, including any PTO payout you owe.

SUTA is also the one place employees sometimes contribute. In most states they do not, but in a small number, including Alaska, New Jersey, and Pennsylvania, employees pay a share of state unemployment tax as well.

What Payroll Tax Actually Costs You

Here is where the rates become a number you can put in a budget.

What a $60,000 employee costs you in payroll tax
Salary you agreed$60,000
The number in the offer letter
Employer Social Security+$3,720
6.2 percent. Your money, not theirs
Employer Medicare+$870
1.45 percent, no cap
FUTA+$42
0.6 percent of the first $7,000. More in a credit reduction state
SUTA+$300 to $2,000
Wildly variable. Depends on your state and your own layoff history
Your payroll tax costAbout $4,900 to $6,600
Roughly 8 to 11 percent on top of salary
What the employee sees on their stubNone of it
Your entire employer share is invisible to them
Illustrative. If you are budgeting a hire at their salary figure, you are budgeting wrong by roughly a tenth, before benefits, before workers compensation, before a laptop. This is the number that surprises every first-time employer, and it is entirely predictable.

Roughly 8 to 11 percent above salary, in payroll tax alone. Before benefits. Before workers compensation. Before equipment.

And note the last row of that table, because it is the source of a persistent asymmetry. Your entire employer share is invisible to the employee. They see their own 7.65 percent on the pay stub and reasonably conclude that is the cost of these programs. It is half the cost. You paid the other half, and there is nowhere they could have learned that.

What worked for me
I budgeted our first two hires at their salary. Not carelessly. I simply did not know there was anything else, and nothing I read told me. The offer said $60,000 and $60,000 went into the model, and about four months later I noticed our payroll cost was running consistently around nine percent above what I had projected and I could not work out why. It was the employer match. Every dollar of Social Security and Medicare my employees paid, I was paying again, quietly, and it never appeared on any document I was looking at because it does not appear on a pay stub. The fix took thirty seconds: I added a line to the hiring model called employer tax, set it at ten percent, and stopped being surprised. If you are about to make your first hire, do that before you make the offer.

Deposits and Deadlines: The Part That Actually Matters

Everything above was arithmetic your provider does automatically. This is the part that can hurt you, and it is the part almost no guide covers properly.

The first thing to understand is that filing is not paying. You deposit the money throughout the quarter and you file a return summarizing it afterwards. A perfect Form 941 does not help you if the deposits were late. The penalties attach to the deposits.

You do not choose your schedule

Your deposit schedule is assigned to you. You do not choose it.
Monthly schedule depositor
Who: You reported $50,000 or less in the lookback periodWhen: Deposit by the 15th of the month following the month of the paydaysIn practice: All the paydays in March get deposited by April 15
Semiweekly schedule depositor
Who: You reported more than $50,000 in the lookback periodWhen: Paydays Wednesday to Friday: deposit by the following Wednesday. Paydays Saturday to Tuesday: deposit by the following FridayIn practice: A Friday payday means a deposit by the following Wednesday. Not the end of the month
Next-day rule
Who: You accumulate $100,000 or more of liability on any single dayWhen: Deposit by the next business day, whatever your normal scheduleIn practice: And it automatically converts you to semiweekly for the rest of this year and all of next
New employer
Who: Your first year, with no lookback historyWhen: Treated as monthly, because your lookback liability is zeroIn practice: Unless the next-day rule triggers, which it can, on a big bonus run
The lookback period is the twelve months ending the previous June 30. Which means your schedule for this year was determined by what you did eighteen months ago, and if you have grown, you may be on the wrong schedule right now without knowing it.

Per IRS Topic 757, your schedule is determined by your total tax liability during a lookback period, being the twelve months ending the previous June 30. Report $50,000 or less and you are monthly. More and you are semiweekly.

Read that carefully, because it has a consequence people miss. Your schedule this year was set by what you did eighteen months ago. If you have grown, you may have crossed the threshold, and the IRS moved you to semiweekly, and you are still depositing monthly because that is what you have always done.

The $100,000 Next-Day Rule Is a Trap for Growing Companies
Accumulate $100,000 or more of tax liability on any single day and you must deposit it by the next business day, whatever your normal schedule says. And it does not stop there: triggering this rule automatically converts you to a semiweekly depositor for the remainder of the year and for the entire following year. The thing that triggers it is rarely regular payroll. It is a large one-off event: an annual bonus run, a commission payout, a rapid hiring push. Which means the day you do something good for your team may also be the day you silently change your deposit obligations for the next eighteen months.

Deposits key off the payday, not the work

A point that matters more than it sounds. The IRS is explicit that deposit rules are based on when wages are paid, not earned. Wages earned in June but paid in July belong to the July deposit obligation.

Which means if you change your pay schedule, you change your deposit rhythm. A semiweekly depositor moving payday from Friday to Tuesday has just changed which day their deposit is due, and that is exactly the kind of thing that generates a penalty in a month when nobody was thinking about it. The mechanics are covered in the arrears guide, and the practical consequences for your bank balance in the pay schedule guide.

How the money actually moves

Federal tax deposits are made electronically, through the Electronic Federal Tax Payment System. Your payroll provider almost certainly does this for you, and you should confirm that they do, and confirm which schedule they think you are on, and confirm it again if your business grows meaningfully. Note that the debit hits your account before the money reaches employees, which interacts with the timing covered in the direct deposit guide.

Per IRS guidance on depositing and reporting employment taxes, the deposit and the return are separate obligations with separate deadlines, and satisfying one does nothing for the other.

Penalties: The Business Ones

Miss a deposit and the penalty escalates by the day. This is the mild version of what can happen.

The failure-to-deposit penalty, which escalates by the day
1 to 5 days late2%
The gentle one. It is still real money
6 to 15 days late5%
It more than doubles
More than 15 days late10%
And now it is serious
More than 10 days after an IRS notice15%
The top tier. You were told, and you did not fix it
This is the business penalty, and it is the mild one. The penalty that can follow you personally, after the company is gone, is in the next section, and it is a different order of thing entirely.

Note what that ladder is measured in. Percent of the deposit, not a flat fee. Which means the penalty scales with your payroll, and a business with thirty employees is not paying thirty dollars for being a week late.

And note the top tier. Fifteen percent applies when you are more than ten days past an IRS notice. That is the tier for employers who were told and did not act, and the IRS does not treat that the same way it treats an honest oversight.

The Schedule B Trap for Semiweekly Depositors
If you are a semiweekly depositor, you must file Schedule B with every Form 941, reporting your tax liability by the day the wages were paid, not by the day you deposited. Skip it, or fill it in wrong, and the IRS may average your liability across the quarter and then assess a failure-to-deposit penalty on every deposit that does not line up with the averages. Which means you can be penalized for deposits that were, in fact, entirely correct, simply because you did not tell them which days the liability arose on.

The Penalty That Follows You Home

Now the section that this entire article exists for. Everything above is a business cost. This is not.

The federal income tax and the employee share of FICA that you withhold are trust fund taxes. You are holding the employee's money in trust for the government. It was never yours, not for a moment, and the IRS treats it as government property from the instant it is withheld from the paycheck.

One Hundred Percent, Personally, and It Survives Bankruptcy
Per IRS guidance on the Trust Fund Recovery Penalty: a person responsible for withholding, accounting for, or depositing employment taxes who willfully fails to do so can be held personally liable for a penalty equal to the full amount of the unpaid trust fund tax, plus interest. And the IRS defines the terms bluntly. A responsible person can be an officer, a partner, a sole proprietor, or an employee of any form of business. And you are acting willfully if you pay other expenses of the business instead of the withholding taxes.

Read that last sentence again. It is not about fraud. It is not about hiding money. Paying other bills instead of the deposit is the definition.

The decision that destroys people

And now the specific case, which is the reason this article is written the way it is.

The decision that destroys people, and it feels like the decent one
Cash is short. You have enough to pay your people or enough to make the tax deposit, and not both. Your team has rent and mortgages and children. The IRS is an institution. You pay your people, intending to catch up next month.
The IRS position on this is settled, and it is brutal. Paying net wages to employees when funds are not available to pay the withholding taxes is a willful failure. If you cannot cover both, you have a duty to prorate the available funds between the government and the employees. And for this purpose, an employee owed wages is merely another creditor, so preferring them over the government is itself the willfulness.
The compassionate choice is the one that makes you personally liable. If you are ever in this position, do not decide it alone at eleven at night. Call an accountant or a tax attorney that day, because the correct answer is counterintuitive and the cost of the intuitive one is your house.

That is not an interpretation and it is not a scare story. It is the settled position, reflected in the IRS Internal Revenue Manual and the case law it cites: the payment of net wages to employees when funds are not available to pay the withholding taxes is a willful failure; a responsible person has a duty to prorate the available funds between the government and the employees; and for this purpose, an employee owed wages is merely another creditor of the business, so a preference for employees over the government constitutes willfulness.

Sit with what that means. The humane instinct, the one that says my people have families and the IRS can wait a month, is the instinct that makes you personally liable.

What responsible person actually means

Wider than you think, and it is not about job titles.

DetailWhy it matters
Who can be liableOfficers, partners, sole proprietors, and employeesIncluding a bookkeeper, controller, or office manager
The testWhether you had the power to direct which creditors got paidNot your title. Your actual authority over the money
Following ordersAn employee who merely paid bills as directed is not responsibleBut one who decided which bills to pay is
WillfulnessVoluntarily, consciously, intentionally. Or reckless disregardNo evil intent required. Plain indifference is enough
Joint and severalThe IRS can assess the full amount against each responsible personThey will collect from whoever has the assets. Once
BankruptcyNot dischargeableIt follows you after the company is gone
What it coversWithheld income tax and the employee share of FICANot the employer share. That is the company's debt, not yours

The row about the bookkeeper deserves a moment, because owners assume the exposure is theirs alone. It is not. Anyone who had significant control over which bills were paid, and knew or should have known the taxes were unpaid, is in scope. That includes the person you hired to handle the money precisely so that you would not have to, which is worth saying out loud to them before they find out from a letter. It is one of the sharper edges in HR compliance.

If You Are Ever in This Position, Do Not Decide It Alone
Cash is short, payroll is Friday, and the deposit is due. Do not resolve this at eleven at night with a spreadsheet and your conscience. The correct answer is counterintuitive, it is legally specific, and the cost of the intuitive one is unbounded and personal. Call an accountant or a tax attorney that day. There are options, including prorating, and there are payment arrangements, and there are ways of structuring a bad month that do not end with a federal tax lien against your home. What there is not, is a version of this where you quietly pay your people and it turns out fine.

Per the IRS page on the TFRP, the way to avoid it is stated in one line: make sure all employment taxes are collected, accounted for, and paid to the IRS when required. Make your deposits on time. That is the entire prevention strategy, and it works, and it is available to everybody.

The Cash Flow Reality Nobody Models

The section above was about what happens when you get it wrong. This one is about how to never be in that position, and it is entirely a cash flow problem.

Payroll is bigger than payroll

When you run a $20,000 payroll, $20,000 does not leave your account. Here is what actually goes.

ComponentRoughlyWhen it leaves
Net pay to employeesAbout $14,000On or before payday, via ACH
Withheld taxes: income tax and employee FICAAbout $6,000On your deposit schedule. It was never yours
Your employer FICA matchAbout $1,530With the deposit. This is your money
FUTA and SUTAA few hundredQuarterly, or with the return if small
What actually leaves your accountAbout $21,500Not $20,000. And not all on the same day

Illustrative, and the shape is what matters. Your $20,000 payroll is a $21,500 cash outflow, and the components leave on different days.

Which produces the specific trap. The net pay goes out on payday. The deposit goes out later. And in the gap between them, there is money in your account that is not yours, and it looks exactly like working capital, and it is available to spend, and spending it is the thing that ends businesses.

The Float Is Not a Facility
For a few days each cycle, you are holding thousands of dollars of your employees' withheld tax. It sits in your operating account. It clears against your balance. And if you are having a difficult month, it is the easiest money in the world to reach for, because it is right there and nobody is asking for it yet. That float is not a credit facility. It is a trust, and treating it as short-term liquidity is precisely the behaviour the Trust Fund Recovery Penalty exists to punish. Employers who go under on payroll tax almost never set out to steal anything. They borrowed from the float, once, in a bad month, and never caught up.

What to actually do about it

1
Model payroll at 110 percent of gross, not at gross
Every payroll forecast should include the employer tax on top. If your model says $20,000, your bank needs about $21,500. This single change prevents most surprises.
2
Know the deposit date, not just the pay date
Two different days, two different amounts. Put both in the cash flow forecast. Most owners track only the pay date, which is why the deposit arrives as a shock.
3
Consider a separate account for withheld taxes
Some businesses move the withheld portion out of the operating account the moment payroll runs. It sounds fussy. It is the single most effective structural protection available, because you cannot spend what is not there.
4
Never let a slow month reach the deposit
If a customer pays late and payroll is Friday, the answer is a credit line, an invoice chased, a founder loan, or a difficult conversation with a supplier. The answer is not the deposit. It is never the deposit.
5
Watch the quarters where the wage base resets
Employer FICA is heaviest early in the year, when nobody has hit the Social Security wage base yet, and tapers as high earners cross it. Your payroll tax cost is not flat across the year.

The third item is the one worth taking seriously. Moving the withheld money into a separate account on payday feels like an overreaction right up until the month you would otherwise have spent it. It costs nothing, it takes one transfer, and it converts a temptation into an impossibility.

If You Are Already Behind

Everything so far has been about doing it right. But a great many people find an article like this because they have already got it wrong, and nobody writes that section, so here it is.

You have more options than you think, and the worst thing you can do is nothing.

Penalties can be removed. Ask.

The failure-to-deposit penalty is not automatically permanent. The IRS has a formal relief mechanism, and small employers routinely fail to use it because they do not know it exists.

A Clean Three-Year History May Erase the Penalty Entirely
The IRS operates an administrative waiver, historically called First Time Abate, that removes failure-to-file, failure-to-pay, and failure-to-deposit penalties for a taxpayer with a clean compliance record. Per IRS guidance on administrative penalty relief, the test is that the same return type was timely filed for the prior three years, or twelve consecutive quarters, and that no penalty was assessed in that window. You do not need an excuse. You need a clean record. And this relief is being replaced by an Automatic Exemption from Penalty, which applies without you having to ask for it.

Read that again if you have just been penalized for a single late deposit and you have otherwise been careful for years. There is a very good chance that penalty can be removed, and the process may be as simple as a phone call.

Reasonable cause, and the two excuses that do not work

If you do not have a clean three-year history, the second route is reasonable cause: you exercised ordinary business care and prudence, and were nevertheless unable to comply.

ReasonGenerally accepted?Note
Serious illness or death, of you or immediate familyYesWith documentation. Dates matter
Fire, natural disaster, or destruction of recordsYesThis is the paradigm case
Unavoidable absenceYesIf genuinely unavoidable and documented
Erroneous written advice from the IRSYesBut it has to be in writing
Inability to obtain records despite ordinary careSometimesYou have to show the ordinary care
You did not have the moneyNoLack of funds is explicitly not reasonable cause
Your accountant was supposed to do itNoReliance on a tax professional does not excuse you
You did not knowNoLack of knowledge is not a defense

The two rows at the bottom are the ones that matter, because they are the two things every employer in trouble actually says.

Lack of funds is not reasonable cause. That is stated explicitly, and it is worth sitting with, because it is the precise situation most employers who miss a deposit are actually in. Not having the money is not an excuse for not depositing the money.

Relying on your accountant is not reasonable cause. You are responsible for complying with tax law even when somebody else handles your taxes. You should know what your provider files, and get proof that the deposit was made on time. Delegating the task does not delegate the liability, and this is worth knowing before you assume your provider has it covered.

You made an error on a return

Errors on a Form 941 are corrected with Form 941-X, the adjusted employer's quarterly return. It is a real mechanism, it is used routinely, and discovering that you overstated or understated your liability is not a catastrophe if you correct it promptly.

The important detail is timing. Underpayments of employment tax can generally be corrected without interest if the amount is paid by the time the adjusted return is filed. Wait, and interest begins accruing from that point. Finding the error is not the expensive part. Sitting on it is.

If you have already received an IRS notice

Do not put it in a drawer. This is the single most common and most expensive response, and it is understandable, and it makes everything worse.

1
Read it and identify what it actually says
A notice about a late deposit is not a notice about an audit. Find the form, the tax period, and the notice number. Those three things determine everything that follows.
2
Note the deadline, because the penalty tier depends on it
The failure-to-deposit penalty jumps to 15 percent once you are more than ten days past a notice. The clock in that notice is real and it is running.
3
File anything unfiled, first
The IRS generally requires current filing compliance before it will consider any relief. Requesting abatement while returns are missing gets denied on procedural grounds.
4
Ask about abatement
By phone, or in writing with Form 843. If you have a clean three-year history, mention it. That is the highest-probability route available and it is frequently granted.
5
Get a professional if trust fund money is involved
The line between a business penalty and a personal one is the trust fund, and the moment unremitted withheld tax is in play, the exposure changes character entirely. That is the point to stop handling it yourself.
6
Arrange to pay what you actually owe
Payment arrangements exist. Abatement removes penalties; it does not remove the underlying tax, and the tax has to be dealt with either way.
The Trust Fund Penalty Is a Different Conversation
Ordinary penalties can be abated on a phone call with a clean history. The Trust Fund Recovery Penalty cannot. Relief from it generally requires an appeal, establishing that you should not have been assessed it in the first place, which is a materially harder argument on a materially higher stake. Which is why the moment you realize that withheld tax has gone unremitted, rather than merely late, is the moment you stop reading articles and call a tax professional. Everything before that line is administration. Everything after it is personal.

The Forms

Four of them carry the whole thing, plus a state layer that varies.

Filing is not paying. These are the forms; the deposits are separate.
Form 941
Quarterly federal return: income tax withheld plus both shares of FICAWhen: By the last day of the month after each quarter ends
Form 944
The annual version, for very small employersWhen: Only if the IRS has notified you to file it. Do not just decide to
Form 940
Annual FUTA returnWhen: By January 31. Deposits are quarterly once liability exceeds $500
Form W-2
Annual wage and tax statement, per employeeWhen: To employees and to the SSA by January 31
Schedule B
Daily liability detail, for semiweekly depositorsWhen: With every Form 941. Skip it and the IRS may average your liability and penalize you on the averages
State returns
State income tax withholding and SUTAWhen: Varies by state. Usually quarterly
The distinction that trips up new employers: the return is a summary, the deposit is the money. Filing a perfect Form 941 does not help you if the deposits were late, and the penalties attach to the deposits, not to the return.

Notice that Form 941 mixes the two categories: the income tax you merely withheld sits on the same return as the FICA you actually paid. That is convenient administratively and it is exactly why owners lose track of which money was theirs.

Form 940, by contrast, is pure employer cost. There is no employee column on it, because there is no employee contribution to FUTA. Keep the filings with your other records, to the standards in the guide on how long to keep employee records.

The one exception to depositing

If your total tax liability for a quarter is less than $2,500, you may generally pay it with your timely filed return rather than making deposits. That is a genuine relief for the smallest employers, and it is the only circumstance in which the deposit rules relax.

Note the word timely. The exception depends on the return being filed on time. It is not a licence to be late.

What Counts as Wages for Payroll Tax

A question that sounds trivial and is not, because the answer determines the base every rate is applied to.

PaymentSubject to FICA?Note
Salary and hourly wagesYesThe obvious case
OvertimeYesWages are wages
Bonuses and commissionsYesSupplemental wages, but fully subject to FICA
Tips reported by the employeeYesAnd you owe the employer match on them
SeveranceYesStill wages, even after employment ends
PTO paid outYesIt is compensation
Group-term life insurance above $50,000YesImputed income. Subject to FICA, though income tax withholding is not required on it
Employer contributions to a qualified retirement planNoThe employer contribution is not FICA wages
Employee 401(k) contributionsYesPre-tax for income tax. NOT pre-tax for FICA. This surprises everyone
Health premiums under a Section 125 planNoThese genuinely reduce FICA wages
Accountable plan reimbursementsNoSubstantiated expenses are not wages
Nonaccountable allowancesYesA flat car allowance with no substantiation is wages

Three rows in that table cause almost all the confusion.

The 401(k) row. A traditional 401(k) contribution reduces the employee's taxable income for income tax, so their withholding drops. It does not reduce FICA wages. Social Security and Medicare are calculated on the full gross, before the retirement deduction. So an employee who increases their contribution sees their income tax fall and their FICA stay exactly where it was, which looks like an error and is not.

The Section 125 row. Health premiums taken through a cafeteria plan do reduce FICA wages, which means they save the employee income tax and FICA, and they save you your matching FICA as well. That is a genuine saving on both sides and it is one of the few free lunches in payroll.

The tips row. Restaurants: you owe the employer FICA match on reported tips, which is money you never touched, paid on income that came from a customer to a server. It is a real cost and it is easy to forget when pricing a menu.

The wider question of what belongs in the wage base at all is covered in the gross pay guide.

State Payroll Taxes, and Why Multi-State Is Painful

Everything above is federal. The state layer sits on top and it is where the administrative burden actually lives.

What varies by stateRangeNote
State income tax withholdingNine states have none at allThe rest vary in rate and in method
SUTA rateFrom under 1 percent to over 6 percentExperience-rated. Your own claims history moves it
SUTA wage baseVaries enormouslySome states tax far more than the federal $7,000
Employee SUTA contributionA few states require oneAlaska, New Jersey, Pennsylvania
Disability and family leave taxesSeveral states have themNew York and New Jersey, among others
Local income taxSome citiesOhio and Pennsylvania are notable for this
RegistrationRequired in every state you have an employeeBefore you run payroll there. Not after

Two things to take from that.

The law that applies is the law of the state where the employee works, not where you are incorporated. Hire one remote person across a state line and you have acquired a new set of registrations, rates, forms, and deadlines.

You must register before you run payroll there, not after. This catches employers who hire a remote person quickly and sort out the paperwork later, and discovering you were not registered is a different and worse conversation than doing it in the right order. It is the same trap that catches employers with pay transparency laws: the obligation attaches to where the work happens.

One Remote Hire Doubles Your State Complexity
A business operating in one state has one set of state obligations. A business with a single employee in a second state has two, and the second one is unfamiliar, and nobody in the company has done it before. This is not an argument against hiring remotely. It is an argument for knowing that the cost of a remote hire includes a state registration and an ongoing filing obligation, and for asking your payroll provider whether they handle it before you make the offer rather than afterwards.

Contractors, and Why Misclassification Is Pursued So Hard

If a person is a 1099 contractor rather than a W-2 employee, your entire payroll tax obligation disappears.

W-2 employee1099 contractor
Income tax withholdingYou calculate, withhold, remitNone
Social Security and MedicareYou match 7.65 percentNone. They pay both halves themselves
FUTA and SUTAYou pay bothNone
Deposit scheduleAppliesDoes not exist
Trust fund exposureYesNone. There is nothing withheld to hold in trust
Year-end formForm W-2Form 1099-NEC
Your payroll tax cost8 to 11 percent above wagesZero

Read the last row and the enforcement posture explains itself. Calling someone a contractor rather than an employee saves you around a tenth of what you pay them, immediately, plus the entire administrative apparatus above.

The Saving Is the Motive, and the Motive Is What They Look For
The tax difference between an employee and a contractor is not a rounding error. It is material, immediate, and obvious to every agency involved. Which is why misclassification carries back taxes, interest, and penalties, and why the tests for who is genuinely a contractor do not care what your contract says. The saving is not a reason to classify someone as a contractor. It is the reason you will be looked at if you do. The tests are in the guide to independent contractors.

If You Pay Yourself

Founders ask this constantly and the answer turns entirely on structure.

If you areYou payNote
A sole proprietor or partnerSelf-employment tax: both halves of FICA, 15.3 percentYou are employer and employee at once. You pay both sides
An S corp owner taking a salaryNormal payroll taxes on the salaryThe salary must be reasonable. This is heavily scrutinized
An S corp owner taking a distributionNo FICA on the distribution portionWhich is why the reasonable salary requirement exists at all
A C corp employeeNormal payroll taxes, like anyone elseYou are an employee of your own company

The self-employment tax rate is 15.3 percent, which is exactly the combined employee and employer FICA, because that is precisely what it is. You can deduct the employer-equivalent half when computing your income tax, which softens it without removing it. Setting your own pay schedule is a separate decision from setting your own salary, and both matter.

The S corp salary-versus-distribution question is a real planning area and a real audit risk. It is not something to decide from an article. Take advice.

Your First Employee: What Happens on Day One

The moment you hire your first person, a set of obligations switches on simultaneously, and most first-time employers discover them in the wrong order.

1
You need an EIN before anything else
The federal employer identification number. It is free, it takes minutes, and nothing downstream works without it. Get it before the person starts, not after.
2
You must register with the state for withholding and for unemployment
Two separate registrations in most states, and they are separate from your business registration. Do this in the state where the employee physically works.
3
You must report the new hire to the state
New hire reporting is a legal obligation, typically within twenty days of the start date, and it is separate from everything else. It is how child support enforcement finds people.
4
You need a Form W-4 and a Form I-9
The W-4 sets their income tax withholding. The I-9 verifies work authorization and has its own deadlines. Both belong in your onboarding pack.
5
You are now a monthly depositor, probably
A new employer has no lookback history, so the liability is treated as zero, which makes you monthly. Unless a single day of liability hits $100,000, which is unlikely on your first hire.
6
Your first Form 941 is due the quarter after they start
By the last day of the month following the quarter end. Your provider will file it. You should know it happened.
7
You will pay roughly ten percent more than the salary
In payroll tax alone. Know this before you make the offer, because it is the difference between a hire you can afford and one you cannot.

The step that catches people is the second one, and it catches them because of remote hiring. You register in the state where the employee works. If your business is in one state and your first hire is in another, you are registering somewhere unfamiliar, and you must do it before the first payroll runs there.

The full onboarding sequence, including the forms, is in the new hire paperwork guide and the new hire reporting guide.

How to Actually Run This

The whole thing, in order, for a business that has just hired its first person.

1
Get an EIN
The federal employer identification number. Free, from the IRS, and you cannot do anything else without it.
2
Register in every state where an employee physically works
Not where you are incorporated. Where they sit. Before you run payroll there, not after. Each state has its own registration for withholding and for unemployment.
3
Use a payroll provider
This is the one piece of advice in this article that is not nuanced. The tax filing alone justifies the cost, and the failure modes of doing it yourself are not proportionate to the saving.
4
Confirm which deposit schedule you are on
Ask your provider. Ask them again if you grow, because the lookback period means your schedule can change without you noticing.
5
Know when the money leaves your account
Not when it reaches the employee. When your provider debits you to fund the payroll and the deposits. That is the date your bank balance has to be right.
6
Keep the trust fund money separate in your head, and ideally in fact
The withheld portion is not your working capital. Some businesses hold it in a separate account, which sounds excessive right up until the month it saves them.
7
Reconcile quarterly
Your Form 941 should reconcile to your payroll records and to your deposits. If it does not, find out why in April, not in an audit.
8
Never solve a cash problem with the deposit
This is the rule. If you take one thing from this article, take this one. The money you withheld is not available to you, in any circumstances, for any reason, however good.
The Rule That Prevents Almost All of It
Treat the withheld taxes as though they have already left your account, because in every sense that matters, they have. That money belongs to your employee and to the government. It sat in your bank for a few days as a matter of mechanics, not as a matter of ownership. An employer who genuinely internalizes this never faces the choice in the section above, because the money was never available to be chosen with. Everything else in payroll tax compliance is administration, and your provider handles it. This one is a decision you make, once, in advance.

Reconciling, and why you should do it in April

Once a quarter, three numbers should agree: what your payroll records say you owed, what your Form 941 reports, and what you actually deposited.

If they do not agree, something is wrong, and the cheapest possible moment to discover that is now, while the quarter is fresh and the person who ran it still remembers. The most expensive moment is during an examination, three years later, when the person has left and nobody can explain the discrepancy.

CheckWhat should matchWhy it matters
WagesYour payroll register against Form 941 line 2If these differ, one of them is wrong and you need to know which
Withheld income taxPayroll register against Form 941This is trust fund money. Errors here are the expensive kind

Deposits madeYour bank statements against the returnA return that reports more than you deposited is a penalty waiting to happen
Year to dateQ4 return against the W-2s you issueJanuary is when a year of small errors becomes one visible one

Your provider does the arithmetic. You are checking that the arithmetic was done on the right numbers, which is a different thing, and it is the one part of this that nobody can do for you.

Common Mistakes

These recur, and the last one is in a different category from all the others.

The Recurring Failures
Budgeting a hire at their salary and being surprised by roughly ten percent of employer tax on top. Believing you pay some portion of federal income tax, and building it into a cost model where it does not belong. Forgetting FUTA entirely, because $42 is too small to remember. Not knowing whether you are in a credit reduction state, and therefore not knowing your actual FUTA rate. Assuming SUTA is fixed, when it is experience-rated and rises with your own layoffs. Matching the Additional Medicare Tax, which you are not required to do. Being on the wrong deposit schedule because the lookback period moved you and nobody told you. Triggering the $100,000 next-day rule with a bonus run and not realizing it converted you to semiweekly for eighteen months. Skipping Schedule B as a semiweekly depositor and being penalized on averaged liability. Hiring a remote employee and running payroll in a state where you are not registered. Putting an IRS notice in a drawer, when the penalty tier escalates ten days after it arrives. Assuming a penalty is permanent, when a clean three-year history may get it removed on a phone call. Assuming your provider has it covered, when reliance on a tax professional is explicitly not a defense. And spending withheld trust fund taxes to make payroll, which is the one mistake on this list that can follow you home after the company is gone.

The unifying error is treating the money in your payroll account as though it is all yours. Some of it is. Most of it is not.

The portion you withheld belongs to your employee and to the government. You are holding it in trust, for a few days, as a mechanical convenience. The entire structure of penalties around payroll tax exists because that distinction is easy to blur when cash is tight, and because the government has learned, over a very long time, exactly how tempting it is. The rest of the recurring small-employer errors are collected in the HR processes guide.

Key Takeaways
Payroll taxes fund Social Security, Medicare, and unemployment. FICA is shared: the employee pays 7.65 percent and you match it. FUTA and SUTA are yours alone.
Your total payroll tax cost is roughly 8 to 11 percent above salary, and none of it appears on the employee's pay stub.
You pay no part of federal income tax withholding and no part of the Additional Medicare Tax. You withhold both and remit them.
Social Security stops at an annual wage base, so both your cost and their deduction fall away late in the year and reset in January.
You do not choose your deposit schedule. It is assigned based on a lookback period, and it can change without you noticing if you have grown.
Accumulate $100,000 of liability on a single day and you must deposit next business day, and you are automatically semiweekly for eighteen months.
Failure-to-deposit penalties escalate from 2 percent to 15 percent by the day. That is the business penalty and it is the mild one.
Withheld taxes are trust fund taxes. A responsible person who willfully fails to remit them can be personally liable for 100 percent, and it is not dischargeable in bankruptcy.
Per the IRS, paying your employees instead of the deposit when you cannot do both is itself willful. You have a duty to prorate.
Your $20,000 payroll is a $21,500 cash outflow, and the components leave on different days. Model at 110 percent of gross.
The withheld money sits in your account for days before the deposit is due. That float is not a credit facility, and borrowing from it once is how businesses end.
A failure-to-deposit penalty is not permanent. A clean three-year compliance history may get it removed entirely, and the process can be a phone call.
Lack of funds is explicitly not reasonable cause, and neither is relying on your accountant. Delegating the task does not delegate the liability.
The rule that prevents nearly all of this: treat the withheld money as though it has already left your account, because it has.

Frequently Asked Questions

What is payroll tax?

Payroll taxes are taxes on wages that fund specific social insurance programs: Social Security, Medicare, and unemployment insurance. They are flat-rate taxes, unlike income tax which is progressive, and they are shared between employer and employee. FICA covers Social Security and Medicare, with the employee paying 7.65 percent and the employer matching it. FUTA and SUTA fund unemployment and are paid almost entirely by the employer. Federal income tax withholding is administered on the same forms and deposits, but it is paid entirely by the employee.

Who pays payroll tax, the employer or the employee?

Both, and the split matters. The employee pays 6.2 percent Social Security and 1.45 percent Medicare, and the employer matches both, so each side pays 7.65 percent and the combined FICA rate is 15.3 percent. Unemployment taxes, FUTA and SUTA, are paid almost entirely by the employer, with a handful of states requiring an employee contribution to SUTA. Federal and state income tax withholding comes entirely out of the employee's pay: the employer collects and remits it but pays none of it.

How much is payroll tax?

The employee pays 7.65 percent of wages in FICA, comprising 6.2 percent Social Security up to an annual wage base and 1.45 percent Medicare on everything. The employer pays a matching 7.65 percent, plus FUTA at an effective 0.6 percent on the first $7,000 of each employee's wages, plus state unemployment tax that varies enormously by state and by the employer's own claims history. For an employer, the total payroll tax cost is typically 8 to 11 percent on top of the salary.

What is the payroll tax rate?

Social Security is 6.2 percent from the employee and 6.2 percent from the employer, up to an annual wage base that adjusts each year. Medicare is 1.45 percent from each side with no cap. An Additional Medicare Tax of 0.9 percent applies to employee wages above $200,000, with no employer match. FUTA is 6.0 percent statutory on the first $7,000, reduced to an effective 0.6 percent by the state credit. SUTA rates vary by state and are experience-rated to your own layoff history.

What payroll taxes do employers pay?

Four. The employer share of Social Security at 6.2 percent, up to the annual wage base. The employer share of Medicare at 1.45 percent, uncapped. FUTA, the federal unemployment tax, at an effective 0.6 percent on the first $7,000 of each employee's wages. And SUTA, the state unemployment tax, which varies by state. Notably, employers pay no part of federal income tax withholding and no part of the Additional Medicare Tax, both of which they withhold and remit but never pay.

What is the employer portion of payroll taxes?

7.65 percent of wages in FICA, matching the employee exactly, plus unemployment taxes that the employee generally does not pay at all. On a $60,000 salary, the FICA match alone runs to roughly $4,590, plus about $42 in FUTA and whatever your state charges in SUTA. None of it appears on the employee's pay stub, which means the true cost of employing someone is meaningfully higher than their gross pay and the employee has no way of knowing it.

How much do employers pay in payroll taxes?

Roughly 8 to 11 percent on top of gross wages, before any benefit. On a $60,000 employee, that is about $3,720 in employer Social Security, $870 in employer Medicare, $42 in FUTA, and anywhere from a few hundred to a couple of thousand in state unemployment tax depending on your state and your claims history. Budgeting a hire at their salary figure understates the cost by at least a tenth, which is the single most common surprise for a first-time employer.

How do payroll tax deposits work?

You do not choose your deposit schedule; it is assigned based on your total tax liability during a lookback period, being the twelve months ending the previous June 30. If you reported $50,000 or less, you are a monthly depositor and deposit by the 15th of the following month. Above $50,000 and you are semiweekly, depositing within a few days of each payday. And if you ever accumulate $100,000 of liability on a single day, you must deposit by the next business day and you are automatically moved to semiweekly.

What happens if I deposit payroll taxes late?

An escalating failure-to-deposit penalty. Two percent if you are one to five days late, five percent at six to fifteen days, ten percent beyond fifteen days, and fifteen percent if you are more than ten days past an IRS notice. That is the business penalty. Far more seriously, the withheld portion of payroll tax is a trust fund tax, and failing to remit it can make a responsible person personally liable for the full amount, regardless of the corporate structure.

What is the Trust Fund Recovery Penalty?

It is the IRS mechanism for collecting unpaid withheld taxes from a person rather than from a company. If you are a responsible person and you willfully fail to pay over the trust fund taxes, you can be held personally liable for a penalty equal to 100 percent of the unpaid amount, plus interest. It covers the withheld income tax and the employee share of FICA, but not the employer share. It is not dischargeable in bankruptcy, and it can reach a bookkeeper or office manager as well as an owner.

What if I cannot afford both payroll and the tax deposit?

Get advice immediately, because the intuitive answer is the dangerous one. The IRS position is that paying net wages when funds are not available for the withholding taxes is a willful failure, and that a responsible person has a duty to prorate the available funds between the government and the employees. For this purpose an employee owed wages is treated as just another creditor, so preferring them over the government is itself evidence of willfulness. The compassionate choice is the one that creates personal liability.

What forms do I file for payroll taxes?

Form 941 quarterly, reporting federal income tax withheld and both shares of Social Security and Medicare. Form 940 annually for FUTA. Form W-2 to each employee and the Social Security Administration by January 31. Some very small employers file Form 944 annually instead of 941, but only if the IRS has notified them to. Semiweekly depositors also file Schedule B with each 941, reporting liability by the day wages were paid. And state returns, which vary.

Do I pay payroll taxes on contractors?

No, and that saving is precisely why misclassification is pursued so aggressively. You withhold no income tax, pay no FICA match, owe no FUTA or SUTA, and issue a Form 1099-NEC rather than a W-2. The contractor pays self-employment tax covering both halves of FICA themselves. Treating an employee as a contractor saves you eight to eleven percent immediately, which is exactly the motive the classification tests are designed to detect, and the penalties for getting it wrong include back taxes, interest, and penalties.

Do payroll taxes apply to bonuses and commissions?

Yes. Bonuses, commissions, overtime, severance, and tips are all wages, and FICA applies to them exactly as it applies to salary. What differs is the federal income tax withholding: these are supplemental wages, and the IRS permits a flat withholding rate rather than the normal tables. That affects how much is withheld, not how much tax is ultimately owed, and it does not change the FICA treatment at all.

What is the payroll tax wage base?

It is the annual limit on wages subject to Social Security tax. Once an employee's year-to-date wages cross it, Social Security stops being withheld for the rest of the year, and your matching contribution stops too. It adjusts upward most years. Medicare has no wage base at all and continues on every dollar. This is why a well-paid employee's net pay rises in the autumn and why your own payroll tax cost for that person falls at the same moment.

How do payroll taxes work?

Every payday, you calculate the tax on the wages, withhold the employee's portion from their pay, add your own employer portion out of business funds, and deposit the combined amount with the IRS on a schedule the IRS assigned you. Then, quarterly, you file a return summarizing what you deposited. The withholding and the depositing are continuous; the filing is periodic. Missing a deposit is penalized even if the return is perfect, because the penalties attach to the money, not to the paperwork.

What is the difference between payroll tax and income tax?

Payroll taxes are flat-rate, fund specific programs like Social Security and Medicare, and are shared between employer and employee. Income tax is progressive, funds general government spending, and is paid entirely by the employee. From your side as an employer, the practical difference is that you pay part of the payroll tax out of your own money and you pay none of the income tax. You withhold income tax and remit it, but not a dollar of it is your cost.

Are payroll taxes deposited with every paycheck?

Not necessarily, and this is where employers get confused. The tax liability arises with every paycheck, but the deposit is due on a schedule, either monthly or semiweekly, and neither of them is every payday. A monthly depositor accumulates the liability from all the paydays in a month and deposits it by the 15th of the following month. A semiweekly depositor deposits within a few days of each payday. Your provider handles the timing; you should know which schedule you are on.

What is a lookback period?

The twelve months ending the previous June 30, and it is how the IRS decides your deposit schedule for the coming year. If your total reported tax liability during that window was $50,000 or less, you are a monthly depositor. If it was more, you are semiweekly. The consequence people miss is that your schedule this year was set by what you did eighteen months ago, so a business that has grown may have been moved to semiweekly without noticing and may still be depositing on the old rhythm.

Do I owe payroll tax on a 401(k) contribution?

Yes, and this catches almost everybody. A traditional 401(k) contribution reduces the employee's taxable income for income tax purposes, so their income tax withholding drops. It does not reduce the wages subject to Social Security and Medicare. FICA is calculated on the full gross, before the retirement deduction. Health premiums under a Section 125 cafeteria plan behave differently and genuinely do reduce FICA wages, which saves both the employee and you.

Do I owe payroll tax on tips?

Yes. Tips reported by an employee are wages for FICA purposes, which means the employee pays Social Security and Medicare on them and you owe your matching employer share. That is money you never handled, going from a customer to a server, on which you nonetheless owe 7.65 percent. It is a real cost for any tipped business and it is easy to leave out when pricing a menu.

What is EFTPS?

The Electronic Federal Tax Payment System, which is how federal tax deposits are actually made. Your payroll provider almost certainly uses it on your behalf, and you should confirm they do. The important thing to know is not the mechanics but the timing: the deposit leaves your account on a schedule that is separate from when your employees are paid, and knowing which day your bank balance has to be right is the difference between a smooth month and a penalty.

Can I be personally liable for my company's payroll taxes?

For the withheld portion, yes, and the corporate structure does not protect you. The Trust Fund Recovery Penalty allows the IRS to assess a penalty equal to 100 percent of the unpaid trust fund taxes against any responsible person who willfully failed to remit them. Responsible person is defined by actual authority over the money rather than by job title, and it can include a bookkeeper. Willfulness includes paying other business expenses instead of the tax. And the liability is not dischargeable in bankruptcy.

What should I do if I am about to miss a payroll tax deposit?

Call an accountant or a tax attorney the same day, before you decide anything. The intuitive move, paying your staff and catching up on the tax next month, is the one that the IRS treats as willful and that creates personal liability. There are options, including prorating the available funds and arranging payment terms, and there are ways of handling a bad month that do not end with a lien against your home. What there is not, is a version where you quietly skip the deposit and it turns out fine.

What are employment taxes?

It is the IRS umbrella term for everything covered in this article: federal income tax withholding, Social Security and Medicare taxes under FICA, and federal unemployment tax under FUTA. In everyday use, employment taxes and payroll taxes mean the same thing, though a purist would note that income tax withholding is administered alongside the payroll taxes without technically being one. The distinction does not matter operationally, because they are deposited together and reported on the same return.

How much is employment tax for a small business?

As an employer, expect to pay roughly 8 to 11 percent above gross wages. That comprises 6.2 percent Social Security and 1.45 percent Medicare, both matching what the employee paid, plus about $42 per employee per year in FUTA, plus state unemployment tax that varies from under one percent to several percent depending on your state and your own claims history. On a ten-person payroll of $600,000, that is roughly $50,000 to $65,000 a year in employer payroll tax alone.

Do payroll taxes apply to part-time employees?

Yes, in full. There is no part-time exemption from FICA, FUTA, or SUTA, and no minimum hours threshold below which payroll taxes stop applying. A person who works four hours a week is an employee, their wages are wages, and every rate in this article applies to them exactly as it does to a full-time person. The only thing that changes is the amount, because the base is smaller.

What is Schedule B and do I need it?

Schedule B accompanies Form 941 and reports your tax liability by the day the wages were paid, rather than by the day you deposited. You need it if you are a semiweekly depositor. Skipping it or completing it incorrectly gives the IRS grounds to average your liability across the quarter and then assess failure-to-deposit penalties on every deposit that does not match the average. Which means you can be penalized for deposits that were, in fact, entirely correct.

Can I handle payroll taxes myself without a provider?

Legally yes, practically no, and this is the one piece of advice in this area that is not nuanced. The rates change annually, the deposit schedules are assigned rather than chosen, the state layer multiplies with every state you hire in, and the penalty for getting it wrong ranges from an escalating percentage to personal liability that survives bankruptcy. The cost of a payroll provider is small and the failure modes of not having one are not proportionate to the saving.

What happens to payroll taxes when an employee is terminated?

Nothing changes about the tax treatment. Final wages are wages: FICA applies, income tax is withheld, and the amounts go into your normal deposit for that period. Severance is also wages and is fully subject to FICA. What does change is the timing, because several states require final pay considerably faster than your normal cycle, and a payment made outside the usual run still carries its own deposit obligation on the schedule you are on.

Is there a payroll tax for very small employers?

The taxes apply from your first employee, with no small-business exemption. But there is one genuine relief: if your total tax liability for a quarter is less than $2,500, you may generally pay it with your timely filed Form 941 rather than making deposits during the quarter. That is a real simplification for the smallest employers, and it depends on the return being filed on time. It is not a licence to be late.

Can a payroll tax penalty be removed?

Often, yes, and employers routinely fail to ask. The IRS operates an administrative waiver that removes failure-to-deposit penalties for taxpayers with a clean compliance history, meaning the same return type was timely filed for the prior three years with no penalties assessed. You do not need an excuse; you need a clean record. The process can be as simple as a phone call. This relief is being replaced by an automatic version that applies without you having to request it, which is a meaningful improvement.

What counts as reasonable cause for a payroll tax penalty?

Serious illness or death, fire or natural disaster, destruction of records, unavoidable absence, and erroneous written advice from the IRS. What does not count is more important: lack of funds is explicitly not reasonable cause, which is awkward because it describes the situation most employers who miss a deposit are actually in. And relying on your accountant is not reasonable cause either. You remain responsible for compliance even when somebody else handles the work.

My accountant missed a deposit. Am I still liable?

Yes. The IRS is explicit that reliance on a tax professional does not generally excuse a failure to file or deposit on time. You are responsible for complying with tax law even if someone else handles your taxes, which means you should know what your provider files and obtain proof that deposits were made when they were supposed to be. Delegating the task does not delegate the liability, and this is worth understanding before you assume it is handled.

How do I correct an error on Form 941?

With Form 941-X, the adjusted employer's quarterly federal tax return. It is a routine mechanism and discovering an error is not a catastrophe if you act on it. The timing matters: an underpayment of employment tax can generally be corrected without interest if the amount is paid by the time the adjusted return is filed. Wait, and interest starts running from that point. Finding the error is not the expensive part. Sitting on it is.

What should I do if I get an IRS notice about payroll taxes?

Not put it in a drawer, which is the most common and most expensive response. Read it, identify the form, period, and notice number, and note the deadline, because the failure-to-deposit penalty jumps to 15 percent once you are more than ten days past a notice. File anything unfiled first, because relief is generally denied while returns are missing. Then ask about abatement. And if unremitted withheld tax is involved rather than merely late tax, stop and call a professional, because that is a different order of problem.
