Arrears: What It Means and Why Your Payroll Uses It
Arrears has two opposite meanings: a normal payroll schedule and an overdue debt. What each means for employers, and how to run payroll in arrears.
Arrears
One word with two nearly opposite meanings, and a complete employer guide to both: the standard US payroll schedule, and the debt you do not want
Somebody told you your payroll runs in arrears, and it sounded like an accusation. It is not: it is standard practice in American payroll, and the alarm is a problem with the word rather than with your payroll. A dictionary will define the word for you; this guide shows you how to tell its two meanings apart and what each one asks of you as an employer.
Here is what makes this word genuinely confusing rather than merely unfamiliar. Arrears has two meanings that are almost opposites. One describes a standard payment schedule where you pay for work after it is done. The other describes a debt: money that was due, was not paid, and is now overdue. Same word. A rent payment in arrears means the tenant is behind. A payroll paid in arrears means nothing is wrong.
The payroll meaning gets the most depth, because it is the one you deal with every two weeks: how the cycle works, why it is the standard, whether it is legal, how it interacts with taxes, what it does to a new hire's first paycheck, and how to switch to it without breaking anything. The debt meaning follows, because it lands on your desk too, as unpaid invoices, property tax bills, and child support withholding orders that carry real legal obligations for you as the employer.
It is written for a small business with nobody doing HR full time. FirstHR is an onboarding and HR platform, not a payroll provider, and I will not pretend otherwise: you should run payroll through a dedicated provider. What I build into FirstHR is the layer around it, the onboarding, records, and communication that determines whether your new hire understands their pay schedule or discovers it the hard way. This is general information rather than legal or tax advice, and payroll rules vary by state and change over time.
What Arrears Actually Means
Arrears refers to a payment made after the obligation it covers has already arisen. That is the root idea, and everything else follows from it. The confusion comes from the fact that the same structure can be entirely intentional or entirely accidental, and the word does not tell you which.
Think about what happens when you hire an electrician. They come, they do the work, they send an invoice, and you pay it. Nobody thinks that is strange. Nobody calls the electrician late for not asking for money before they arrived. That is payment in arrears, and it is the ordinary pattern for paying for services, because payment following performance is the natural order of things.
Payroll works the same way, and for the same reason. Your employee works a period. The period ends. You count what they did. You pay them for it. The only thing that makes this feel odd is the word, and the word is only doing what it always does, which is describe a payment that comes after the thing it pays for.
Why the word feels negative
Because most of the time you encounter it in the wild, something has gone wrong. A letter about rent in arrears is a demand. A notice about taxes in arrears is a warning. A mortgage in arrears is the phrase in the news story about foreclosures. The word has acquired a smell, and it carries that smell into contexts where nothing is wrong at all.
So when a payroll provider tells a founder that their employees are paid in arrears, the founder hears an accusation. They are not being accused of anything. They are being told, in slightly archaic language, that they pay people for work they have already done.
Paid in Arrears vs In Arrears
This is the distinction the entire article rests on, so it is worth being precise. The difference is not subtle in substance, even though it is nearly invisible in the language.
Read the two columns and notice what actually separates them. The test is whether the payment date has passed. In the left column, the payment date is in the future and you will meet it. In the right column, the payment date is in the past and you did not.
That is the whole thing. Everything else, the rent, the taxes, the payroll, the child support, is just a different context wrapped around the same test. Has the due date passed without payment? Then it is a debt. Has the due date not arrived yet? Then it is a schedule.
Why does this matter beyond vocabulary? Because employers act on it. An owner who believes paying in arrears means they are behind will try to move to paying in advance, which will break their overtime calculation, create a permanent stream of corrections, and cost them money and accuracy in exchange for solving a problem that never existed.
How Payroll in Arrears Actually Works
Mechanically, it is four steps, and only two of them involve you doing anything. Here is a standard biweekly cycle end to end.
The gap between step 2 and step 4 is the arrears. It exists for a reason that becomes obvious once you look at it directly: you cannot count something until it stops happening.
As long as the pay period is open, an employee can still work another hour, still ring another sale, still receive another tip. The moment you try to calculate pay for a period that is still running, you are guessing.
Why the processing gap exists
Between the period closing and the money landing sits the work of actually running payroll, and it is not instant. Timesheets have to be submitted and approved. Overtime has to be calculated against the workweek, not the pay period, a distinction that trips up more employers than it should. Deductions have to be applied. Then the file goes to your payroll provider, who usually needs a few business days of lead time to move money through the banking system.
You could compress this. Some providers offer same-day or next-day funding at a premium. But compressing it does not eliminate the arrears; it just shortens it. The structural fact remains: work first, count second, pay third.
What the employee experiences
Almost nothing, after the first check. From their perspective, money arrives every other Friday, reliably, and what it covers is a period that ended the previous Sunday. Once the cycle is established, the arrears is invisible.
The arrears is only visible at two moments in an employee's life with you. The beginning, when they wait for their first check, and the end, when they leave and are still owed a period. Both get their own section below, because both are where the problems live.
Arrears vs Current vs Advance
There are three ways to time a payroll relative to the work, and only one of them holds up for most businesses. Here they are side by side.
| Paid in arrears | Paid current | Paid in advance | |
|---|---|---|---|
| Payday relative to period | After the period closes | On or near the last day of the period | Before the period ends, sometimes before it starts |
| What the check covers | Only completed work | Mostly completed work, plus an estimate of the last few days | Work that has not happened yet |
| Overtime | Accurate. It is already known | Estimated, then corrected on a later check | Impossible to know. Pure guess |
| Tips and commissions | Accurate. Already reported and closed | Usually deferred to the next check anyway | Unworkable |
| Corrections needed | Rare. Only genuine errors | Routine. Built into the model | Constant, including clawbacks |
| Works for hourly staff | Yes | Poorly | No |
| Works for salaried staff | Yes | Yes | Yes, with risk |
| Risk if someone quits mid-period | You owe them. Normal | Small overpayment possible | You have paid for work that will never happen |
| Where it fits | Standard practice for US employers, and the only accurate option for hourly, tipped, or commissioned pay | Salaried-only payrolls with no variable pay | Hard to justify, since every early check is an unsecured advance |
Look at the corrections row, because it is the one that decides this. A current schedule does not eliminate the problem of not knowing the final numbers; it just moves the problem downstream.
On a current schedule you estimate, you pay, and then next period you fix it. Forever. Every pay run carries a tail of adjustments from the last one, and every adjustment is a chance to make an error and a conversation with a confused employee.
Advance pay is worse than it looks. You are paying for work that has not been performed by a person who has not yet decided to stay. If they quit on Tuesday of a period you have already paid for, you are chasing a former employee for money, which is legally fraught and practically hopeless. Recovering it through a payroll deduction is heavily constrained.
Why Employers Pay in Arrears
Employers pay in arrears because, for any payroll that includes hourly, tipped, or commissioned pay, there is no viable alternative. The reason is not tradition, not laziness, and not cash flow, even though the schedule happens to help with cash flow too.
You cannot pay overtime you do not know about
Overtime under the Fair Labor Standards Act (FLSA) is calculated on the workweek. Per 29 CFR 778.105, a workweek is a fixed and regularly recurring period of 168 hours, or seven consecutive 24-hour periods. The hours an employee works over 40 inside that window are the overtime hours.
That definition is what forces the arrears. You cannot know whether an employee crossed 40 hours until the week is over. If you paid them before it ended, you paid the wrong amount, and you now owe a correction. Every week. Forever.
You cannot pay tips that have not been reported
Tipped employees report tips after they receive them. A restaurant that tried to pay tips in advance would be inventing numbers. Arrears is not a preference here; it is a precondition.
You cannot pay commissions on deals that have not closed
Same structure. A commission is earned when the deal closes, and until it closes there is nothing to pay. Sales-heavy businesses often run commissions on an even longer arrears than base pay, paying them a month or a quarter behind, precisely because the numbers take that long to settle.
You cannot correctly deduct from wages you have not calculated
Deductions come out of gross pay, and gross pay depends on hours. Health premiums, retirement contributions, garnishments, and everything else in the stack all sit downstream of a number you do not have until the period closes.
The upshot is simple. If you employ anyone hourly, tipped, or commissioned, you pay in arrears, because there is no other way to be accurate. If you employ only salaried staff with fixed pay and no variable component, you have a theoretical choice, and arrears still keeps you on one payroll model if you later add hourly or commissioned staff.
The Pay Period Calendar
Arrears looks different at each pay frequency, and the differences are more consequential than employers expect. Here is what each one actually does.
| Frequency | Periods per year | Typical lag to payday | Best for |
|---|---|---|---|
| Weekly | 52 | About 5 days after period close | Hourly, trades, staffing, high-turnover teams |
| Biweekly | 26 | About 5 to 7 days after period close | The most common US schedule. Mixed hourly and salaried |
| Semi-monthly | 24 | About 5 to 10 days after period close | Salaried teams. Aligns cleanly with month-end accounting |
| Monthly | 12 | Up to a month after work begins | Least common, often restricted to exempt employees by state law |
Biweekly is the most common of the four. According to the Bureau of Labor Statistics Current Employment Statistics survey (February 2023), 43.0 percent of private establishments pay biweekly, against 27.0 percent weekly, 19.8 percent semi-monthly, and 10.3 percent monthly.
Weekly
Period runs Monday to Sunday. Payday is usually the following Friday. Short arrears, roughly five days, and it is the friendliest structure for employees who live paycheck to paycheck.
The cost of weekly pay is that you run payroll 52 times a year, and if your provider charges per run, that is a real line item. Accurate time clock practices matter more here, because there are 52 chances a year to get a rounding rule wrong.
Biweekly
Period runs two weeks, closing on a Sunday, paying the following Friday. Twenty-six pay periods, which means two months a year contain three paydays, and if you budget monthly, those months will surprise you until you plan for them.
The thing that catches employers about biweekly is that it does not align with the calendar. Pay periods drift across month boundaries, which makes month-end accruals messy and makes it harder to explain to a new hire when they will be paid, because the answer depends on which day of the cycle they started.
Semi-monthly
Twice a month, typically the 1st through the 15th and the 16th through the end of the month, paying a few days after each closes. Twenty-four periods, aligned to the calendar, which accountants love.
The catch with semi-monthly is overtime. Because the FLSA workweek does not align with a semi-monthly period, a single workweek can straddle two pay periods, and 29 CFR 778.104 is explicit that each workweek stands alone and may not be averaged with another.
That mismatch is a routine source of error in businesses that run semi-monthly with hourly staff, and it is a good reason to run biweekly instead if you have any nonexempt employees.
Monthly
The least common schedule in the US, and in many states not permitted for nonexempt employees at all. The arrears here is severe: an employee who starts on the 2nd of the month may not see money until the 5th of the following month, which is over a month of work with no income.
Paid monthly in arrears means the pay period is the calendar month and the payday falls in the first days of the month after it closes. You will meet the same phrase outside payroll: a vendor who bills monthly in arrears is invoicing you for the month that just finished, not the one about to start.
The New Hire First Paycheck Problem
When you pay in arrears, a new employee waits a long time for their first paycheck. Not because anything is wrong, but because they have to work a period before there is a period to pay them for, and then the processing lag runs on top of that.
This is the part that is easy to overlook, and it is the part that costs you something real.
None of the long waits in that table is hypothetical. They follow from the calendar whenever a start date lands early in a pay period, because start dates are set for the convenience of the manager and the candidate, not for the convenience of the payroll calendar, and where Monday the 5th sits in the pay cycle is easy to overlook in a hiring conversation.
Why this is worse than it sounds
Think about who this person is. They have just left another job, or come out of a period of unemployment, which means their income has probably already been interrupted. They may have moved for this role. They have new commuting costs, possibly new childcare costs, possibly a deposit on a new apartment. They accepted a salary figure and mentally started spending it.
And then, more than two weeks in, they check their account and there is nothing there. They do not know whether they have been forgotten, whether the paperwork failed, whether the company is in trouble, or whether this is normal. Asking about money in the first month at a new job can feel risky, so they may not ask. They sit with it instead.
The fix is not to restructure your payroll. The fix is a sentence. The next section is that sentence.
How to Communicate It During Onboarding
Say the date. Not the policy, not the schedule, not the mechanism. The date itself.
A new hire does not need to understand what arrears means. They need to know that on Friday, January 23rd, money will arrive, and that between now and then there will be no money, and that this is expected. If they know that, the whole problem evaporates. If they do not, no amount of policy documentation will help them, because they will not read it until after they are already worried.
The document side of this is worth automating, because computing the first pay date by hand for each offer is exactly the kind of small task that gets skipped when you are busy. That is the connection to onboarding: not that FirstHR runs your payroll, because it does not, but that the offer letter, the acknowledgment, and the day-one checklist are where this either gets communicated or gets forgotten.
The day-one items sit naturally in your onboarding checklist, alongside the tax forms and the I-9. Adding one line about the first pay date costs nothing and it is the line people remember.
Is Paying in Arrears Legal?
Yes. The more interesting question is what the law actually regulates, because it is easy to worry about the wrong thing.
What federal law says
The FLSA does not tell you how often to pay. It contains no pay frequency requirement at all. What it requires is that wages be paid on the regular payday for the pay period covered, which is a rule about consistency, not about timing relative to the work.
So at the federal level, paying in arrears is not merely permitted. It is the structure the statute presupposes.
What state law says, and this is where it matters
Pay frequency is a state question, and the states differ enormously. Some mandate weekly pay for certain classes of worker. Some allow monthly only for exempt employees. Some cap the number of days that may elapse between the end of a pay period and the payday, which is a direct limit on how long your arrears may be.
The lag rules are the real constraint
The part that actually bites on arrears specifically is not frequency but lag, meaning how many days after the period ends you may wait to pay. Several states cap this.
If your state says wages must be paid within a set number of days of the period ending, then your arrears window is legally bounded, and a processing delay that pushes you past it is a violation even though your payday was consistent.
This is a genuinely easy thing to get wrong, because it is invisible until someone complains. Your payroll runs on the schedule you set, and the schedule feels fine, so a mismatch with the statute can run unnoticed until someone checks.
Multi-state teams
The law that applies is the law of the state where the employee works, not where your company is registered. A company headquartered in Florida, which sets no frequency requirement, employing one remote person in a state that requires pay at least semi-monthly, must pay that person at least semi-monthly. With distributed teams this is now the normal case rather than an edge case.
Payroll Taxes and Deposit Timing
The entire federal tax deposit system is keyed to when wages are paid, not to when they are earned. That one fact settles the legality question more convincingly than anything above.
Sit with the implication. If the federal government expected you to pay employees during the period they worked, the deposit rules would key off the work period. They do not. They key off the payday, which is a rule that only makes sense in a world where payday and work period are different things.
How the deposit schedule works
Two schedules exist, determined by your total tax liability during a lookback period, a fixed window in the past that the IRS uses as your reference. Per IRS Topic 757, here is how both schedules work, along with the two special cases that sit on top of them.
| Depositor type | Who it applies to | When you deposit |
|---|---|---|
| Monthly schedule | Reported $50,000 or less in the lookback period | By the 15th of the month following the month of the paydays |
| Semiweekly schedule | Reported more than $50,000 in the lookback period | Paydays Wed to Fri: deposit by the following Wednesday. Paydays Sat to Tue: deposit by the following Friday |
| Next-day rule | Any depositor accumulating $100,000 or more in a deposit period | By the next business day, regardless of your normal schedule |
| New employers | First calendar year in business, or the first two for a Form 944 filer | Lookback liability is treated as zero, so monthly, unless the next-day rule triggers |
Notice that both schedules are described in terms of paydays, not work periods. The federal deposit calendar is a function of when money leaves your account for employees, which is the arrears payday.
What this means practically
It means your deposit deadlines move when your pay dates move. If you change your pay schedule, you change your deposit rhythm, and a semiweekly depositor who shifts payday from Friday to Tuesday has just changed which day their deposit is due. This is the kind of thing your payroll provider handles automatically and that you will handle wrong if you ever do it yourself.
It also means the failure-to-deposit penalties, which scale with lateness, attach to the payday too. There is no argument available that the wages were earned earlier, because the IRS has already told you that is not the test.
Switching from Current to Arrears
Some employers, usually ones who started with a single salaried founder and grew, find themselves paying current and needing to move to arrears once they hire hourly staff. This is doable and it has one unavoidable problem.
The gap
Moving from current to arrears means moving the payday later. Which means there is a stretch of time where employees have worked, the old payday would have paid them, and the new payday has not arrived yet. That gap is real money and it does not go away by being ignored.
You have to bridge it. There is no clever structure that avoids it, because you are genuinely asking people to go longer than usual between paychecks, once.
Arrears Beyond the Regular Paycheck
Everything so far has been about base wages. But the regular paycheck is only part of what you pay, and almost everything else runs on an even longer arrears than the wages do.
Bonuses, commissions, and other supplemental wages
Bonuses, commissions, and similar payments are supplemental wages, and they are structurally arrears in a more extreme way than base pay. A quarterly bonus is paid after the quarter it rewards. A commission is paid after the deal closes, which may be weeks after the salesperson did the work that closed it.
Sales teams frequently run commissions on a lag of a month or more behind base pay, for a reason that is entirely about arrears: the numbers do not settle immediately. Deals fall through, customers churn within a clawback window, invoices go unpaid. Paying commission too quickly means paying on revenue that has not actually arrived, and then trying to take it back.
The withholding also works differently on supplemental wages, which is its own source of confusion when the check lands smaller than the employee expected.
Retroactive pay and back pay
Retro pay is arrears made visible. You approve a raise effective the 1st, but payroll does not catch it until the run on the 20th, so the next check contains the new rate plus a retro adjustment for the days at the old rate. That adjustment is, literally, wages paid in arrears for a period that has already closed.
Back pay is a heavier version of the same thing: wages owed for past work that were never paid, often because of a misclassification, a miscalculation, or a settlement. That is arrears in the debt sense as much as the timing sense, and it is where the two halves of this word meet.
Severance
Severance is paid entirely after the employment relationship has ended, which makes it about as arrears as a payment can be. It is supplemental wages, it is fully taxable, and it does not escape any of the withholding obligations, including an active income withholding order.
Contractors, vendors, and invoices
You pay your 1099 contractors in arrears without ever thinking about it. They work, they invoice, you pay on terms.
Same with vendors. Net 30 terms are arrears with a name: the goods arrived, the invoice followed, and you pay thirty days later. The entire commercial credit system runs on billing in arrears, and the only time it becomes a problem is when someone stops paying, at which point they are in arrears in the other sense.
Direct deposit adds its own lag
Direct deposit moves the real date, because the bank transfer itself takes time. According to the Consumer Financial Protection Bureau, an ACH payment, the bank-to-bank transfer that carries direct deposits, can clear the same business day it is entered, but the way the network processes payments and screens them for fraud means a transfer can also take days to complete. That settlement window sits on top of the arrears rather than inside it.
A normal week looks like this. Your payday is Friday, you submitted the direct deposit file on Tuesday, and the money genuinely lands Friday. But if you submit late, the money lands the following Monday, and the employee does not care about your submission deadline. They care that it was supposed to be Friday.
This is a common source of accidental late payment: the employer thinks they paid on payday because they hit the button, and the employee experiences a missed payday because the money was not there.
The pay stub shows the period, not the payday
Most pay stubs prominently display the pay period, which is the range of dates the work was performed, rather than the payday. That small mechanical detail causes an outsized amount of confusion. The employee looks at a stub dated for January 5 through January 18, received on January 23, and cannot immediately reconcile the dates.
That gap on the stub is the arrears, printed. Most states require you to provide an itemized wage statement, and this is one of the places where a clear statement is worth the effort: an employee who can see the period, the payday, and the hours in a way that reconciles will not come and ask you why the dates do not match.
When You Are in Arrears to an Employee
Now the uncomfortable version. Everything above described paying in arrears, which is fine. This section is about being in arrears to your own employee, which is not.
If you underpay someone, whether by miscalculating overtime, missing a shift on a timesheet, applying the wrong rate, or misclassifying them as exempt when they were not, you owe them wages. Those wages are past due. You are in arrears in the debt sense of the word, and the fact that your payroll schedule is also in arrears in the harmless sense does not help you at all.
How it usually happens
Not through malice. Through arithmetic. A timesheet that came in late and was never reconciled. Overtime calculated on the pay period instead of the workweek, which understates it whenever a workweek straddles two periods. A raise approved but not entered. A commission that closed and was forgotten. A tipped employee whose tip credit left them below minimum wage for the week, which is a violation that the employer usually does not notice at all.
A related trap is whether paid leave counts toward the overtime threshold, which it generally does not.
What to do when you find one
The point of putting this section next to the payroll sections is that they use the same word and mean opposite things. Paying in arrears is your schedule. Being in arrears is your problem. One is how business works. The other is a liability that grows while you are not looking at it.
A note on accrual accounting, since it gets confused with this
Your accountant will tell you that under accrual accounting, wages are recorded as an expense in the period they were earned, not in the period they were paid. That is correct, and it is a different thing from arrears.
The accrual is a bookkeeping entry recognizing that you owe wages for work performed before the period closed. The arrears is the actual timing of the cash leaving your account. They coexist: you accrue the wages in December for the days worked in December, and you pay them in January.
A year-end wage accrual is not a warning sign. It is the accountant correctly recognizing an obligation that is about to be paid on schedule, and neither the accrual nor the arrears means you are behind on anything.
Termination and the Final Paycheck
Arrears has a structural consequence that catches employers at exactly the wrong moment. When someone leaves, you always owe them. Always. By definition. Because arrears means you are permanently one pay period behind, there is no possible moment at which an employee is fully paid up to the present.
An employee who resigns on the last day of a pay period is owed that entire period. An employee terminated in the middle of a period is owed the completed part of it, plus possibly the previous period if the payday for it has not yet arrived.
When the final check is due
Federal law does not require immediate payment of final wages. State law frequently does, and the states diverge sharply.
| Scenario | Common rules across states | What it means for you |
|---|---|---|
| Involuntary termination | Some states require payment immediately or within 24 to 72 hours | You may not have time to run a normal payroll cycle. Plan for an off-cycle check |
| Voluntary resignation with notice | Often due on the next regular payday, sometimes sooner | Usually manageable within your normal cycle |
| Voluntary resignation without notice | Frequently a longer window, such as within 72 hours or the next payday | The employee gave you no notice, so the law usually gives you a little |
| Accrued PTO payout | Required in some states, not in others, depending on whether it is treated as earned wages | This is a separate question from the wages themselves, and it is where the big numbers are |
| Late final payment | Several states impose waiting-time penalties measured in days of wages | This is the expensive one. A few days of delay can cost weeks of pay |
The waiting-time penalty row is the one to be afraid of. In several states, a late final paycheck accrues a penalty equal to the daily wage for every day it is late, capped in California at thirty calendar days of pay.
Waiting-time exposure is not theoretical. It is easily triggered: an employer who assumes the final check can simply ride the next normal payroll run can miss the state deadline without noticing.
The PTO question sits on top
Separate from the wages, you may also owe accrued but unused PTO, depending on your state and how your policy is written. In some states accrued vacation is treated as earned wages that cannot be forfeited and must be paid out.
Edge Cases That Catch Employers
The regular cycle is easy. These are the situations that break it, and every one of them is a situation where the arrears is what creates the problem.
When payday falls on a weekend or a holiday
Your biweekly Friday payday lands on Christmas Day. Or the 15th, on a semi-monthly schedule, falls on a Sunday. What now?
The standard practice is to pay on the preceding business day, not the following one, and several states write it into statute: Connecticut, Delaware, and Maryland all require the earlier date when a regular payday falls on a nonwork day. Not every state agrees: Maine allows payment no later than the following business day.
The logic for paying early is simple: banks are closed, so if you wait until Monday, the employee has gone past their announced payday. Paying early is safe in every state. Paying on the Monday after misses the date you promised, even where the state allows it, and in a state with a lag rule it may also blow through your statutory window.
This one is entirely predictable, which is why it is embarrassing to get wrong. Publish a pay calendar at the start of the year with the adjusted dates already marked, and it never comes up again.
Furloughs and seasonal shutdowns
You furlough the team, or the season ends and everyone goes home. But you are always one period behind, which means the last period they worked is still unpaid at the moment they stop working.
That final period still has to be paid, on the normal payday, at the normal time. A shutdown does not suspend the obligation, and an employer who stops running payroll because nobody is working has just failed to pay wages that were already earned. Run the last cycle even if the office is dark.
The first payroll of a brand new business
Your first pay run is arrears in its purest form. Nobody has been paid anything, everyone has been working, and the first check covers a period that has now closed. It is also the point at which several obligations switch on at once.
Two things are worth knowing. First, per IRS Publication 15, a new employer is a monthly schedule depositor for its first calendar year as a quarterly Form 941 filer, and for its first two as an annual Form 944 filer. The reason is that the lookback liability is treated as zero for any period before the business existed, so the monthly schedule applies unless the next-day rule triggers.
Second, everything you have set up wrong will be discovered on this run, in front of the people who just joined you. Do a dry run before the real one.
When an employee dies
The hardest one, and the one worth having a procedure for before you need it. And it is an arrears problem by definition, because an employee who dies is always owed for a period they already worked.
The tax treatment is genuinely strange and easy to get wrong. Per the IRS instructions for Forms 1099-MISC and 1099-NEC, the rules split on the calendar year.
| Paid in the same year as the death | Paid in a later year | |
|---|---|---|
| Federal income tax withholding | None | None |
| Social Security and Medicare | Yes, withhold as normal | No |
| W-2 box 1 (wages) | Do not include the post-death payment | Do not report on W-2 at all |
| W-2 boxes 3 and 5 | Include the payment, so the credit is recorded | Not applicable |
| Form 1099-MISC | Yes, box 3, issued to the estate or beneficiary | Yes, box 3, issued to the estate or beneficiary |
| Who the check is made out to | The estate or beneficiary. Never the deceased employee | The estate or beneficiary |
Read that first column twice, because it produces a W-2 that looks broken and is not: FICA is withheld and reported in boxes 3 and 5, but the same wages never appear in box 1, and the gross amount also goes on a 1099-MISC to a completely different recipient. That is correct. It is what the IRS instructions require.
Whether unused PTO must be paid out to the estate is a state question and it is often the largest number in the final payment. The rules are the same ones that govern any separation.
Unclaimed wages and escheatment
An employee leaves, you issue the final check, and they never cash it. Or they move without a forwarding address and the direct deposit bounces back. What happens to the money?
You do not get to keep it. Unclaimed wages are subject to state escheatment laws, which require you to attempt to locate the owner and, after a set waiting time called the dwell period, turn the money over to the state. Every state has an unclaimed property regime, the dwell periods differ, and there are reporting requirements and penalties for keeping property you should have escheated.
It is a small amount of money and a real compliance obligation, and it exists precisely because of arrears: you owed them, you tried to pay them, and the debt did not go away when they stopped answering.
Trust fund taxes, and the harshest arrears of all
The most dangerous form of being in arrears that a small business owner can experience has nothing to do with payroll timing. It is failing to remit the taxes you withheld from your employees.
Understand what that means for a struggling business. Cash is tight. Rent is due, the supplier is calling, and the payroll tax deposit is also due. You pay the rent and the supplier, intending to catch up on the deposit next month. That decision, which feels like ordinary triage, is the definition of willful under this rule.
The penalty is 100 percent of the unpaid trust fund tax. It reaches anyone with authority over which bills get paid, which can include a bookkeeper or an office manager as well as the owner. And the corporate structure that shields you from most business debts does not shield you from this one.
If you are ever in a position where you cannot make both payroll and the tax deposit, the answer is to get advice immediately rather than to make the obvious-seeming choice. Being in arrears to the IRS on trust fund taxes is not like being in arrears to a supplier. It follows you home.
When Arrears Means Debt
Now the other half of the word, and this half is exactly as bad as it sounds. Most of this guide so far has described a schedule. The sections that follow describe money that was due and was not paid.
What the amount in arrears means
The amount in arrears is the total that has already come due and has not been paid. It is not the next installment and it is not the whole obligation. It is the accumulated shortfall to date, which is why the same figure is also called the arrears balance or, in legal documents, the arrearage.
The amount of arrears is usually built the same way in every context: add up the payments that were missed, then add whatever interest, late fees, or statutory penalties the contract or the statute attaches to them. That second half is why an arrears balance grows even in a month when nothing new was missed.
Employers meet this figure in three places. An income withholding order states an arrears balance on its face, and that number is what decides your withholding ceiling. An aged receivables report shows what a customer is in arrears for. A property tax notice shows a balance that has been running since the assessment.
One thing worth checking before you act on any of them: the balance you are looking at is a snapshot, not a live figure. Payments made after it was printed will not appear. When the number drives a decision, such as a withholding percentage or a collections call, confirm it with whoever issued it first.
Rent in arrears
If your business leases space and you fall behind, you are in arrears on rent, and commercial leases are generally far less forgiving than residential ones. Late fees accrue, and the remedies available to a commercial landlord, including lockout and acceleration of the remaining term, are frequently harsher than a residential tenant would face.
Note the distinction that catches people signing their first commercial lease. A lease that says rent is payable in arrears is not warning you about anything. It is telling you the rent for a given month is due at the end of that month, which is a cash flow feature and often a favorable one.
Invoices in arrears
Your customer received the work and did not pay by the terms. They are in arrears. Any business that extends payment terms will eventually carry receivables in arrears, and the practical question is not whether it happens but how quickly you notice and how firmly you follow up.
The mirror image is that you bill in arrears too, which is normal: you deliver, then you invoice. Billing in arrears is a business model. Being in arrears on someone else's invoice is a problem.
Taxes in arrears
Property taxes are commonly assessed and billed in arrears, meaning the bill you receive covers a period that has already passed. That is a billing structure.
Being in arrears on your taxes, meaning you owe and have not paid, is a different matter entirely. With payroll taxes specifically, it is one of the most dangerous positions a small business can be in, because unpaid trust fund taxes can create personal liability for the individuals responsible for paying them.
Loans and mortgages in arrears
Missed payments on a business loan or a commercial mortgage. This is the classic escalation path: arrears, then default, then acceleration of the full balance, then enforcement against whatever secured it.
Worth knowing, because it is a nice illustration of how slippery this word is: mortgage interest is typically paid in arrears. Per a Consumer Financial Protection Bureau factsheet, the lag is usually one month: a payment due on November 1 covers the interest that accrued in October. That is a payment schedule, and it has nothing to do with being behind.
Child Support Arrears and Your Legal Duties
This is the section where arrears stops being someone else's problem and becomes yours, because when an employee owes child support arrears, the law hands you obligations, deadlines, and liability if you get them wrong.
Child support arrears are past-due support that a parent owes. Enforcement runs primarily through employers, because wage withholding is by far the most effective collection mechanism available. If you employ a parent who owes support, you will receive an Income Withholding for Support order, and it is not a request. It typically arrives because you reported the hire.
What the order requires of you
The 12-week line in those four ceilings deserves attention, because it is the direct link back to the word. Per DOL Fact Sheet 30, an employee more than twelve weeks in arrears on their support can have an additional five percent of disposable earnings withheld. The arrears status, the very thing this article is about, is what sets your ceiling.
The IRS levy exception, and why the date that matters is not the one you have
Child support outranks essentially every other claim on the same wages: commercial garnishments, wage assignments, state tax levies, student loans. There is exactly one exception, and it has a trap in it.
What counts as earnings, and what does not
The scope is broader than base wages, and narrower in one place that surprises people.
| Payment type | Subject to withholding? | Note |
|---|---|---|
| Wages and salary | Yes | The obvious case |
| Commissions and bonuses | Yes | Compensation for personal services, whatever it is labeled |
| Severance | Yes | Still earnings. The order does not end when employment does |
| PTO payout | Yes | You may garnish PTO for child support |
| Payments to a 1099 contractor | Yes, if an order names them | You must withhold from payments to a nonemployee if an order arrives |
| Cash tips left on the table or added to a card | No | Per DOL, tips are not earnings for garnishment purposes |
| Automatic service charges given to the employee | Yes | A service charge is income to you first, so when you pass it on it is earnings |
| Employer HSA contributions | No | Cannot be garnished |
The tips row is worth flagging for restaurants specifically, because it produces a counterintuitive result: a tipped employee's disposable income for garnishment purposes may be far lower than their actual take-home, and a mandatory service charge is treated differently from a voluntary tip even though the customer experiences them identically.
The precise line, per DOL Fact Sheet 30, runs through the tip credit. The cash wage you pay directly and any tip credit you claim are earnings. Tips the customer leaves beyond that, in cash or added to a card, are not. A service charge is income to you before it is income to anyone else, so once you pass it on it counts.
Lump sums have their own reporting duty
Before you pay a bonus, a commission payout, a severance package, or any other lump sum to an employee with an active support order, you may be required to report the payment to the child support agency in advance and hold it for a period, so the agency can decide whether to claim some or all of it against arrears.
Thresholds and hold periods vary by state, and the federal Child Support Portal offers a lump sum reporting application precisely so employers can notify several states at once. This is a genuinely easy obligation to miss, because a bonus does not feel like a paycheck and it is easy to approve one without checking the garnishment file first. Check first, then pay.
Spousal support works the same way
Alimony and spousal support orders travel on the same track: they generally come to you on the same standardized form, carry the same priority over ordinary garnishments, and require the same prompt withholding. One practical difference is that payments on spousal-only orders often do not go to the state disbursement unit, so read the payment instructions on the order itself rather than assuming.
The administrative fee wrinkle
Most states let you charge the employee an administrative fee for processing the withholding. Per the same federal guidance for employers, if the fee plus the support payment would exceed the CCPA ceiling, you may take the entire fee and pay less support than the order specifies.
The shortfall does not become your debt. It becomes part of the arrears owed by the noncustodial parent, which is a small mechanical detail with a large practical implication: you are never obligated to withhold above the ceiling to cover your own fee.
What to do when the order arrives
Read it. Verify it is on the standardized federal form and has not been altered. Give the employee their copy. Set up the deduction in payroll for the correct pay cycle, converting the amount if the order states a frequency different from yours. Put the remittance deadline on your calendar. And do not let the employee talk you out of it: if they dispute the order, they take it up with the issuing agency, not with you.
Because the order and everything around it is confidential, it belongs in the employee record rather than in the inbox of a line manager. The intake itself, meaning the deadlines printed on the face of the order and the priority against anything else already running, is worked through in the garnishment guide, which covers every order type rather than only support.
What that leaves you holding here is the part that keeps moving, and all of it is driven by the arrears. How far behind the employee is decides your ceiling. Each remittance chips at the balance. Every bonus has to be cleared against it before it is paid. That is a running log rather than a form you fill in once.
Dividends in Arrears
Narrower, but if it applies to you it applies significantly. Dividends in arrears are unpaid dividends that have accumulated on cumulative preferred stock.
A business that has never issued cumulative preferred stock will never encounter this. It becomes relevant the moment you take an investment structured as preferred equity, such as a venture round.
The thing to understand is the ordering. If your preferred is cumulative and you skip dividends for several years, that skipped amount sits there, growing, ahead of the common shareholders in line. Which means it sits ahead of you, the founder.
A company that has been quietly accumulating preferred dividends for five years can discover at an exit that a meaningful slice of the proceeds is spoken for before common sees a dollar.
If you have taken preferred investment and do not know whether it is cumulative, that is worth an hour with the term sheet today rather than a surprise later.
Common Mistakes
These recur, and they span both halves of the word.
Two of those deserve a final word, and both are documentation failures rather than payroll failures, which is a useful thing to notice if you are wondering where to spend your next free afternoon.
The first paycheck failure is the cheapest one on the list to fix. It requires no system, no budget, and no legal advice. It requires a sentence in an offer letter. Leave it out, and you are quietly spending goodwill you did not have to spend, at the exact moment a new employee is deciding whether they made the right call.
The income withholding order failure is the most expensive. It arrives as a form, it looks like paperwork, and paperwork is what busy owners defer. But the deadlines are short, the penalties are real, and the liability lands on you rather than on the employee who actually owes the money. Treat it as what it is, which is a legal order with your name on it, and process it the week it arrives.
Frequently Asked Questions
What does arrears mean?
Arrears has two distinct meanings and they are close to opposites. In payroll, being paid in arrears means being paid for work already completed: the pay period ends, the hours are counted, and payment follows. That is normal, legal, and standard practice for US employers. In finance and law, being in arrears means being behind on a payment that was due and was not made, as in rent in arrears or child support arrears. That is a debt. The difference usually comes down to a single word: paid in arrears is a schedule, while in arrears on its own is a delinquency.
What does paid in arrears mean?
Paid in arrears means you pay employees after they have performed the work, rather than before. An employee works a defined pay period, the period closes, you calculate what is owed including any overtime, tips, or commissions, and you pay on the scheduled payday shortly afterward. The gap between the last day worked and the payday is the arrears. It typically runs three to ten days depending on your payroll frequency and processing time. It is not a late payment, it is not a penalty, and it is not a sign of financial trouble. It is the standard payroll structure in the United States.
Is paid in arrears the same as being late?
No, and the distinction matters enormously. Paying in arrears means paying on your established payday for work in a completed pay period, which is exactly what the law contemplates. A late payment means missing that established payday. Under the Fair Labor Standards Act, wages are due on the regular payday for the pay period covered. If you announced that the pay period ending Sunday the 18th pays on Friday the 23rd, and you pay on Friday the 23rd, you are on time. You have paid in arrears and you have paid promptly, and those are not in conflict.
Is it legal to pay employees in arrears?
Yes, and it is what the federal framework assumes. The Fair Labor Standards Act does not mandate any particular pay frequency; it requires that wages be paid on the regular payday for the pay period covered. That language contemplates a period that ends and a payday that follows. What is regulated at the state level is how often you must pay and, in some states, how many days can pass between the close of a pay period and the day it is paid. Those lag limits are what actually constrain you, and they vary widely, so check the rules in every state where you have an employee working.
Why do companies pay in arrears?
Because it is the only way to pay accurately. You cannot pay overtime for hours that have not been worked yet, you cannot pay commissions on deals that have not closed, and you cannot pay out tips that have not been reported. Any employer with hourly staff, tipped staff, or commissioned staff has no realistic alternative. Paying in advance means guessing, and then correcting the guess later, which creates a permanent stream of adjustments, clawbacks, and errors. Arrears eliminates that entire class of problem by simply waiting until the numbers are known before paying them.
How long is the delay when you are paid in arrears?
Usually between three and ten days from the end of the pay period to the payday, depending on frequency and processing time. A weekly payroll might close Sunday and pay Friday, a five-day lag. A biweekly payroll commonly closes Sunday and pays the following Friday, also about five days. Semi-monthly and monthly schedules often run longer. Several states cap this lag by statute, requiring payment within a set number of days after the period ends, so your maximum lag may be legally determined rather than a matter of preference.
When does a new employee get their first paycheck if you pay in arrears?
Later than they expect, and this is the single most avoidable friction point in onboarding. On a biweekly schedule, someone who starts on the first day of a pay period waits about eighteen days: fourteen days of work plus the processing lag. Someone who starts mid-period waits closer to eleven. A monthly schedule pushes the first payday past the one-month mark. Nothing is wrong when this happens; it is arithmetic. But if you have not told them in advance, they discover it by checking an empty bank account, and that is a terrible first impression from an employer they just joined.
What is the difference between paid in arrears and paid current?
Paid current, sometimes called paying in advance, means the payday falls on or before the last day of the pay period, so part of the check covers work that has not happened yet. Paid in arrears means the payday falls after the period closes, so the entire check covers completed work. The practical difference is accuracy: a current schedule requires estimating the final days of the period and then correcting the estimate on a later check, which only holds up for salaried staff with no variable pay. Arrears requires no estimating at all, which is why it dominates.
Do payroll taxes depend on when wages are earned or when they are paid?
When they are paid. The IRS is explicit that deposit rules are based on when wages are paid, not when they are earned. Wages earned in June but paid in July belong to the July deposit obligation. This is one of the clearest signals that the federal tax framework is built around paying in arrears: the entire deposit schedule keys off your payday rather than off the work period, which would be unworkable otherwise. It also has a practical side: move your paydays and your deposit deadlines move with them, so any change to your pay schedule reshapes your tax deposit calendar as well.
Can I switch from paying current to paying in arrears?
Yes, but it needs to be handled carefully because there is an unavoidable gap. When you move the payday later, there is a stretch where employees have worked but the new payday has not yet arrived, and that gap has to be bridged with a partial check, a bridge payment, or a transition period. You also need to give advance written notice, meet your state's minimum pay frequency at every point in the transition, and never leave anyone unpaid for work already performed. Some states impose specific notice or approval requirements on changing pay schedules, so check before you announce.
How does the final paycheck work when you pay in arrears?
The employee is always owed at least one pay period of work at the moment they leave, by definition, because arrears means you are always one period behind. Whether you must pay it immediately or may wait for the next regular payday depends entirely on state law, and the rules differ sharply. Some states require final wages immediately on involuntary termination. Others allow the next scheduled payday. Getting this wrong is one of the more expensive small-employer mistakes, because several states impose waiting-time penalties measured in days of wages for every day the final payment is late.
What are child support arrears and what does an employer have to do?
Child support arrears are support payments a parent owes and has not made on time. When that parent works for you, expect an Income Withholding for Support order, and processing it is mandatory. Your duties: start deducting promptly, keep the total within the federal CCPA ceiling on disposable income, send each payment to the state disbursement unit generally within seven business days of the pay date, rank child support ahead of other garnishments except certain federal tax liens, and tell the agency when the employee leaves. An employer that ignores an order can be made to pay the amount it failed to withhold, plus penalties and fines.
What are dividends in arrears?
Dividends in arrears are preferred dividends a company skipped and still owes on cumulative preferred stock. With that cumulative feature, a missed dividend does not lapse. It carries forward and keeps adding up, and the whole backlog has to be cleared before common shareholders can receive any dividend at all. A business that has never issued preferred stock with a cumulative feature never deals with this. If you have raised money through preferred shares, though, read the terms, because a growing backlog can quietly become a large claim that sits ahead of the founders.
Does rent paid in arrears mean the tenant is behind?
No, and this is the same trap as with payroll. Rent paid in arrears means the lease schedules each rent payment for the end of the rental period it covers rather than for its start. It is a payment schedule and it is common in commercial leases. Rent in arrears, without the word paid, means the tenant has missed payments and owes money. One word separates a normal contract term from a default. So if a commercial lease you are about to sign makes rent payable in arrears, read it as a cash flow feature, not a warning.
Is paying in arrears bad for employees?
Not inherently. Once the cycle is running, a check arrives on every scheduled payday and the gap between the work and the money goes unnoticed. The one place it genuinely bites is the first paycheck at a new job, where the wait runs to about eighteen days on a biweekly cycle and past a month on a monthly one, while the employee may have moved, may have had a gap in income, and may be counting on that money. That is a real hardship and it is entirely predictable. The fix is not to change your payroll structure. The fix is to tell them the exact date before they start.
Are commissions and bonuses paid in arrears?
Almost always, and usually on a longer lag than base wages. A commission is earned when a deal closes, and it often takes weeks after that for the revenue to settle enough to pay safely, so sales teams commonly run commissions a month or a quarter behind base pay. Bonuses reward a period that has ended by definition. Both are supplemental wages, which also means the federal income tax withholding on them may work differently than on a regular paycheck, producing a smaller check than the employee expected and a conversation you should be ready for.
What does arrears of pay mean?
Arrears of pay, sometimes called salary arrears, means wages owed for a period of work that has already closed. The phrase carries the same double meaning the word always does. In the harmless sense, every employer on an arrears schedule has arrears of pay at every moment: the period your team just finished is earned, unpaid, and due on its normal payday. In the debt sense, arrears of pay means wages that should already have been paid and were not, because a raise was approved and never entered, because overtime was calculated on the pay period instead of the workweek, or because a timesheet was never reconciled. The first is simply your schedule and nothing needs fixing. The second is an underpayment, it is due now rather than eventually, and correcting it on the next payroll run is what keeps an honest arithmetic error from turning into a wage claim.
What is retro pay, and is it the same as arrears?
Retro pay is a correction that pays the difference between what someone was paid and what they should have been paid, usually because a raise took effect before payroll caught up with it. It is arrears in the timing sense: wages for a period that has already closed. Back pay is the heavier relative, covering wages that were owed and never paid at all, often following a misclassification or a settlement. Retro pay is routine administration. Back pay usually means something went wrong, and it sits on the debt side of the word rather than the schedule side.
Can a child support order reach a 1099 contractor?
Yes, and assuming otherwise is a serious mistake. The federal definition of income for a support order is deliberately wide. It is not confined to wages. It covers periodic payments made to an individual whatever their source, and that breadth is the reason the standard order form speaks to any income withholder, not only to employers. Paying someone on a 1099 instead of a W-2 does not put them outside it. There is one genuine limit. Where the contractor operates through an incorporated business, the withholding runs against an individual rather than a company, so your step is to notify the issuing agency instead of deducting.
Does an IRS levy outrank a child support withholding order?
Only if the levy was entered before the underlying child support order was established, and that test is easy to misread. What counts is which one was entered first, not the order in which the paperwork landed with you. For child support, that means the date of the original support order rather than the date on the withholding notice in your file, and that date may not appear anywhere in your file. That is why federal guidance tells you to report the levy to the child support agency that issued the order and let the agency determine which one comes first, instead of deciding it yourself.
Why does my pay stub show different dates than my payday?
Because the stub is labeled with the pay period, meaning the days the work was done, while the payday is the day the money arrives. Those are two different dates, and the gap between them is the arrears. An employee receiving a check on January 23rd for a period running January 5th through January 18th is seeing exactly what they should. The mismatch confuses people regularly, especially on a first paycheck, so explain it once up front rather than answering the same question again and again.
Is arrears the same as accrual accounting?
No, though they are easily confused. Accrual accounting is a bookkeeping rule: the wage expense lands in the period the work happened, whatever month the cash moves. Arrears describes when the cash actually moves. The two sit together without conflict, so December wages are a December expense and a January payment on your normal schedule. That is also why a wage accrual sitting on your year-end balance sheet is nothing to worry about. It records an obligation you are about to meet on time, not one you have already missed.
What happens if payday falls on a weekend or a holiday?
Pay on the business day before it. That is standard practice, and Connecticut, Delaware, and Maryland make it a legal requirement whenever a regular payday lands on a nonwork day, while Maine, for one, lets you pay on the next business day instead. Moving payment to the following Monday puts the money past the date employees were promised, which feels like a missed payday even though nothing was intended. Pushing the date earlier is always safe. Moving it later can also breach a state lag rule that limits how long you may wait after a pay period closes. Hand out a yearly pay calendar with every adjusted date already shown, and nobody has to ask.
Do I still have to run payroll during a furlough or seasonal shutdown?
For the last period worked, yes. Arrears means you are always one pay period behind, so when work stops, the final stretch your team worked has not been paid yet. Those wages were earned before the shutdown, and they are due on the regular payday for that period, exactly as if the business were still running. Closing the doors does not pause that obligation. An employer who skips the run because nobody is on the schedule has simply failed to pay earned wages, which is a wage violation whether or not the office is open.
What do I do when an employee dies and is still owed wages?
They are always owed something, because arrears means you are always a period behind. The tax handling is counterintuitive. If you pay in the same calendar year as the death, you withhold Social Security and Medicare but not federal income tax, report the payment in W-2 boxes 3 and 5 but not box 1, and also issue a Form 1099-MISC in box 3 to the estate or beneficiary. If you pay in a later year, you withhold nothing and report only on the 1099-MISC. Get a Form W-9 from the estate, write the check to the estate or beneficiary rather than to the employee, and confirm under your state's law who is entitled to the money.
What happens to a final paycheck the employee never cashes?
You do not get to keep it. Wages you owed and could not deliver become unclaimed property under your state's escheatment laws. Those laws require a genuine attempt to find the person first. If they stay unreachable past the dwell period, which differs from state to state, you report the funds and hand them over to the state, and holding on to money that should have been escheated can bring penalties. The sum is usually modest, but the duty is real, because the wages were genuinely owed and an unanswered phone does not cancel that debt.
What happens if I cannot afford both payroll and the tax deposit?
Get advice immediately, because the obvious-seeming choice is the dangerous one. The income tax and FICA you withhold from employees are trust fund taxes, meaning money that belongs to your employees and that you only hold until it reaches the government. The IRS states that a responsible person who willfully fails to deposit them can be held personally liable for a penalty equal to the full unpaid amount, and it defines willfully to include paying other business expenses instead of the withholding taxes. Operating as an LLC or corporation offers no protection here, and liability can reach a bookkeeper or office manager as well as an owner.
