What Is a Bonus? An Employer Guide to the 8 Types
A bonus is not one thing. It is eight different promises with different costs, tax treatment, and legal consequences. Here is which one you are giving.
Bonus
Eight different things share this name, and they cost different amounts, are taxed the same way, and have very different legal consequences
The first proper bonus I paid, I announced out loud, in a meeting, with some ceremony. Two weeks later the person came to me, awkward and clearly having rehearsed it, to ask whether there had been a mistake, because the amount that landed was nowhere near what I had said. There had been no mistake. It was the withholding, and I had never thought to mention it.
That was the lesson I learned the hard way, and it is not the biggest one. The same word covers eight distinct promises, and the one you make decides what it costs you, whether the employee can rely on it, and, most consequentially, whether it changes the overtime you owe.
The person who says "I will give you a bonus if we hit the target" has done something legally different from the person who hands over an envelope in December with no explanation. Both said bonus. One of them just increased the hourly rate that their nonexempt employees' overtime is calculated from, and does not know it.
So this is a map rather than an essay: what a bonus is, all eight types, the discretionary distinction that decides everything, how they are taxed, what they really cost, how to size and calculate one, and how to start without an HR department. FirstHR is an onboarding and HR platform, not a payroll provider, and none of this is tax or legal advice.
What a Bonus Is
A bonus is money paid to an employee in addition to their regular wages. That is the definition, and everything interesting is in the qualifications.
Three things in that definition do a lot of work.
The first is that a bonus is not required. No law compels you to pay one, and the FLSA (the Fair Labor Standards Act, the federal wage and hour law) does not mandate them. You are free to have no bonus at all, and plenty of good employers do not, relying instead on non-monetary incentives that cost nothing.
The second is that a promised bonus is a different animal. Your freedom is in whether to have a bonus, not in whether to honor one you announced.
Once you publish criteria, the promise creates an expectation, potentially a contractual obligation depending on your wording, and definitely a wage and hour consequence: it can raise the overtime you owe nonexempt staff, meaning the employees entitled to overtime pay.
The third is that a bonus is wages. It is not a gift for tax purposes, and not an expense sitting outside payroll.
The Internal Revenue Service treats bonuses and awards received for outstanding work as income that belongs on the W-2 (IRS Publication 525), and it costs you your share of FICA, the Social Security and Medicare taxes, on top of the amount itself.
The Eight Types
Here is the map. Every bonus a small business gives is one of these.
Look at the tags on the right, because that is the column nobody puts on a table like this. Five of the eight can change what you owe in overtime: three are tagged as hitting overtime (performance, retention, and attendance or safety), and two depend on how you set them up (year-end and signing).
The three that usually do not (spot bonuses, referral bonuses, and profit sharing) are exactly the three that are hardest to use as a targeted incentive for a specific outcome. That is not a coincidence, and it is the central tension of the whole subject. The mechanisms that tie effort to reward most tightly are precisely the ones the wage laws notice.
STI, AIP, MBO and SPIFF: other names for the same eight
Compensation vocabulary invents names faster than it invents mechanisms. Almost every term below is one of the eight types wearing a different label, and the label changes nothing about the tax or the overtime.
| Name you will hear | What it actually is | Which of the eight it is |
|---|---|---|
| STI, or short-term incentive | Cash tied to a target measured over a year or less, usually expressed as a percentage of salary | A performance bonus |
| AIP, or annual incentive plan | The formal plan document behind a company-wide yearly payout | A performance bonus, paid annually |
| MBO bonus | Paid against objectives agreed with the manager at the start of the period | A performance bonus with individually set targets |
| SPIFF | A short, sharp sales push on one product or one window, paid quickly | A performance bonus on a very short cycle |
| Merit bonus | A lump sum tied to a performance rating, paid instead of lifting base pay | A performance bonus. A merit increase is a raise, which is a different decision entirely |
| Incentive bonus | An umbrella term for anything announced in advance to change behavior | Whichever of the eight applies, and nondiscretionary by definition |
| Quarterly or annual bonus | A payment frequency rather than a type | Whichever type it is, carrying a multi-week regular rate consequence |
| 13th month pay | An extra month of salary paid at year end, a norm in a number of countries outside the US | A year-end bonus in US terms |
| Relocation bonus | Cash toward a move, paid to the employee rather than to a moving company | Wages, taxed as wages, and usually carrying a repayment agreement like a signing bonus |
The name is not the question to ask. Two questions decide everything that follows: did the employee have reason to expect this before they did the work, and is the employee nonexempt. Answer those two and the label on the plan document stops mattering.
Discretionary vs Nondiscretionary: The Distinction That Decides Everything
The difference is whether the employee knew the payment was coming. A payment you announced in advance, or tied to criteria or a formula, is nondiscretionary. One you decided on at or near the end of the period, with no earlier promise, can be discretionary. This is the fork in the road, and almost every employer walks past it without noticing.
| Question | Discretionary | Nondiscretionary |
|---|---|---|
| Did you announce it in advance? | No | Yes |
| Are there published criteria or a formula? | No | Yes |
| Did the employee have reason to expect it? | No | Yes |
| Did you decide the amount at the end, alone? | Yes | No |
| Could they have changed their behavior to earn it? | No | Yes |
| Does it go into the regular rate? | No | Yes, unless another exclusion applies |
Per DOL Fact Sheet 56C, nondiscretionary bonuses are included in the regular rate of pay, and the DOL lists five examples: bonuses based on a predetermined formula, such as individual or group production bonuses; bonuses for quality and accuracy of work; bonuses announced to induce employees to work more efficiently; attendance bonuses; and safety bonuses.
The consequence is direct. If you have a nonexempt employee, pay them a bonus of any of those kinds, and calculate their overtime as one and a half times their base hourly rate, you are underpaying their wages. It happens every week they work overtime, by an amount small enough that nobody will ever complain about it.
The trap this creates is inescapable. To make a bonus motivate anyone, you have to tell them about it in advance. Telling them makes it nondiscretionary. So the thing that makes the bonus work is the thing that makes it count. There is no clever structure that gives you both.
There is a further wrinkle worth knowing before you design an annual plan. A nondiscretionary bonus that covers more than one workweek is spread back across the weeks it was earned in (29 CFR 778.209).
For each of those weeks, you work out what the bonus adds to the hourly rate, and the employee is owed an extra half of that for every statutory overtime hour they worked that week. A quarterly or annual bonus therefore requires recalculating overtime week by week. Almost nobody does this, and it is a quiet, accruing liability.
The work itself is one row per workweek, per person. Doing it once, when the bonus is paid, is a short afternoon. Reconstructing it two years later from a wage claim is not. The discretionary versus nondiscretionary guide works the arithmetic through with the DOL's own figures and carries the top-up worksheet to run it on.
How Bonuses Are Taxed
Bonuses are taxed as wages, with federal income tax withheld under special rules for supplemental pay. The second most common employee complaint about a bonus, after not getting one, is that it was taxed to death. It was not, and being able to say why in one sentence is worth having.
A bonus is supplemental wages, which is an IRS category covering payments that are not regular wages: bonuses, commissions, overtime, severance, and back pay.
| Method | How it works | When you use it |
|---|---|---|
| Percentage method | A flat 22 percent federal withholding on the bonus | When the bonus is paid separately or shown as its own amount, and you withheld income tax from regular wages this year or last. This is the common one |
| Percentage method, above $1 million | 37 percent on supplemental wages over $1 million in a year | Mandatory. Not optional, and not affected by the W-4 |
| Aggregate method | Combine the bonus with regular pay and withhold based on the W-4 | Required when the bonus is lumped into a regular paycheck without its amount shown separately, or when regular wages had no income tax withheld this year or last. Optional otherwise |
| Social Security | 6.2 percent, up to the $184,500 wage base for 2026 | Always. A bonus is wages |
| Medicare | 1.45 percent, no cap | Always |
| State tax | Varies. Some states have their own supplemental rate | Depends where the employee works. Nine states take nothing |
Per IRS Publication 15, the flat withholding rate on supplemental wages is 22 percent for 2026, rising to 37 percent where supplemental wages paid to an employee during the calendar year exceed $1 million. Neither rate is scheduled to lapse, because a federal tax law, Public Law 119-21, permanently extended the individual income tax rates those two figures rest on.
The 6.2 percent Social Security and 1.45 percent Medicare lines are separate from all of that and never optional. Both apply to a bonus exactly as they apply to salary, on the employee side and again on yours (IRS Topic 751).
What a Bonus Actually Costs You
You pay more than the number you announced, and the employee receives less. Both gaps are invisible until somebody looks.
Two numbers in that breakdown are worth remembering.
The employee gets about 70 percent. You said $2,000. About $1,400 arrives. If you have not explained why, the person you just rewarded is now mildly annoyed, which is a remarkable outcome for a transaction in which you gave them money.
The bonus costs you about 108 percent. That is the $2,000, plus your matching Social Security and Medicare, which never shows up on their pay stub and which they will never know about. Budget the bonus at the gross figure plus roughly 8 percent, not at the gross figure.
Bonus or Raise?
A one-off payment or a permanent increase to base pay: this is the decision most small businesses make badly, usually in the direction of the expensive option.
Do the arithmetic on a $3,000 decision. As a bonus, it costs $3,000, once. As a 5 percent raise on a $60,000 salary, it costs $3,000 this year, $3,000 next year, $3,000 the year after, and it inflates the base that every subsequent raise is calculated on.
The asymmetry over five years is the whole decision. The bonus costs up to $15,000 if you choose to repeat it, and the raise costs at least $15,000 whether you choose to or not, because nothing about it is optional after the first conversation.
Neither is wrong. But they answer different questions.
A raise says that market value or scope has genuinely changed and base pay should reflect that permanently. A bonus says that someone did something exceptional and here is a reward for it.
The mistake, and it is enormously common, is giving a raise as a reward for a single strong quarter. You are making a permanent commitment on the strength of one temporary result. Small businesses do it constantly, and four years on, their payroll has ratcheted up and cannot come back down.
Attaching the decision to a documented performance review rather than to a good mood is the cheapest guard against it. A review leaves a dated record of what actually changed, which is what separates a raise you can defend from a raise you regret.
How Much to Pay
The honest answer is that benchmarks matter less than affordability, but here is how to size each type.
| Type | How to size it at a small business | Note |
|---|---|---|
| Year-end or holiday bonus | A flat amount per person that you could afford to repeat next year | Often flat across the team, which is simple and defensible |
| Performance bonus, exempt staff | A percentage of salary that you choose | No sourceable national benchmark exists. Set it against your own margin |
| Performance bonus, hourly staff | A percentage of pay or a flat amount per result, set the same way | And this is the group where the overtime rule bites |
| Spot bonus | Kept well below a performance bonus | Small is the point. Immediacy beats size |
| Signing bonus | A fixed amount, stated in the offer letter | More if the market is tight or the role is hard to fill |
| Referral bonus | A fixed amount per successful hire | Often split: half on hire, half after 90 days |
One national figure is worth having in view. According to the Bureau of Labor Statistics Employer Costs for Employee Compensation survey (June 2026), private industry employers paid $1.33 per hour worked in nonproduction bonuses (payments not tied by any formula to an individual employee's output, such as year-end, holiday, and referral pay).
Those payments made up 2.8 percent of total compensation, the closest thing to a national budgeting anchor that exists. The single most important constraint is not the benchmark, though. It is this: never promise a bonus you could not pay in a bad quarter.
The reputational cost of announcing a bonus and then not paying it is far worse than never having offered one. You have not saved money; you have spent trust, and trust is the thing the bonus was supposed to buy. Size the plan for the worst quarter you can imagine, not for the one you are having.
How to Calculate a Bonus
Pick a base, pick a rate, prorate for time. Almost every bonus calculation at a small business is one of the seven formulas below, and the arithmetic stays deliberately simple, because a bonus nobody can work out in their head is a bonus nobody is motivated by.
| Method | The formula | Worked example |
|---|---|---|
| Percentage of salary | Annual salary x bonus percentage | $60,000 x 8 percent = $4,800 |
| Percentage of salary, prorated | Annual salary x percentage x (months worked / 12) | Started in April, so $4,800 x 9/12 = $3,600 |
| Flat amount per head | One figure, the same for everyone | $1,000 each across 12 people = $12,000 |
| Pool split by salary | Pool x (individual salary / total payroll) | $30,000 pool, $60,000 of a $600,000 payroll = $3,000 |
| Pool split by hours | Pool x (hours worked / total hours worked) | $30,000 pool, 1,600 of 20,000 hours = $2,400 |
| Percentage of a result | Bonus rate x the number being measured | 2 percent of $250,000 in new revenue = $5,000 |
| Target times a rating multiplier | Target bonus x performance multiplier | $4,800 target x 1.25 = $6,000 |
A yearly bonus calculation is the first two rows and nothing more: the base, the percentage, and the fraction of the year worked. A quarterly bonus is the same arithmetic on a shorter clock, which makes it feel more responsive to the person receiving it and costs you four rounds of administration instead of one.
Then there is the structure question, which is separate from the formula. A performance-based bonus structure comes down to three decisions: what single thing gets measured, what shape the payout takes, and what period it covers.
On shape, the usual choice is threshold or tiered. Threshold plans pay nothing until a line is crossed, so they are easy to explain and brutal to miss by a point. Tiered plans pay something for the near miss and take longer to explain.
One step is easy to forget. For a nonexempt employee, the number the formula produces is not the final number: a nondiscretionary bonus covering more than a single workweek lifts the regular rate across the whole period, so the overtime top-up gets calculated after the bonus is known, never before.
What Is Actually Happening With Bonuses
Bonuses are common but unevenly distributed, and the unevenness is the part worth acting on. Just over half of private industry workers, 51 percent, had access to a nonproduction bonus in March 2026, and that average hides a wide spread.
Access ran from 37 percent in service occupations to 61 percent in management, professional, and related occupations. Across the major industry groups, it ran from 27 percent in leisure and hospitality to 76 percent in information, with financial activities at 72 percent.
The takeaway for a small business is not to copy the national picture. Your competition for talent is other small businesses in your sector, not the average across the whole economy, and the thing worth knowing is what the shop down the road is doing.
Starting a Bonus Program Without an HR Team
You do not need a compensation department. You need one decision and one page.
The step people skip is the second one, and it is the only one with a legal consequence. Everything else is a matter of judgment. That one is a matter of law, and finding out afterwards is how a bonus plan becomes a wage claim.
Before the page in step four gets written, the decisions behind it have to be made. This is the sheet you fill in for yourself, with the classification from step two and the net figure from step five built into it. It is not the document the employee receives.
Common Mistakes
These recur, and the first one costs real money.
The unifying error is treating the word bonus as a single thing. It is not. It is eight things, and the differences between them are not stylistic. They determine what you owe, what you can withdraw, and whether your overtime calculation is legal.
Before you pay one, know which of the eight you are giving. That question takes thirty seconds and it is the only one that matters.
Frequently Asked Questions
What is a bonus?
A bonus is any payment an employer makes on top of an employee's regular wages, whether to reward a result, to win or keep someone, or to share profits. No law requires one, and nothing is guaranteed unless you promised it. The word covers eight common forms: performance, year-end or holiday, signing, referral, retention, spot, and attendance and safety bonuses, plus profit sharing. Every one of them counts as wages for tax purposes, and most of them can change how you calculate overtime, which is the part employers almost never know.
What are the main types of employee bonuses?
Eight. A performance bonus for hitting a target. A year-end or holiday bonus, often paid to everyone. A spot bonus, a small immediate award for something specific. A signing bonus to close a candidate. A referral bonus for bringing in a hire. A retention bonus for staying through a date. An attendance or safety bonus. And profit sharing, which distributes a slice of company profits. They differ in cost, in how you announce them, and critically in whether they affect the overtime you owe.
Are employers required to give bonuses?
No. No federal law obliges an employer to pay a bonus, and nothing in the Fair Labor Standards Act requires one. That changes once you promise a bonus. Announcing it in advance with defined criteria sets up an expectation, can create a contractual obligation depending on the wording you used, and makes the bonus nondiscretionary for wage and hour purposes. Put simply, you choose whether to offer a bonus at all, but once you have announced one, you are no longer choosing whether to pay it.
How are bonuses taxed?
As supplemental wages. The IRS allows two federal withholding methods. The percentage method applies a flat 22 percent to the bonus, rising to 37 percent on supplemental wages above $1 million in a calendar year. The aggregate method combines the bonus with regular pay and withholds based on the employee's W-4. Either way, Social Security at 6.2 percent and Medicare at 1.45 percent also apply, exactly as they do to salary. The employee's actual tax liability is settled on their return, so the withholding is a prepayment, not a final bill.
Why is my bonus taxed so much?
Because of how it is withheld, not because the tax on it is higher. Payroll often takes federal income tax from a bonus at the flat 22 percent supplemental rate, and that figure is only a prepayment. When the employee files a return, the bonus is simply added to the rest of their income for the year and taxed at their normal rates. Someone whose top tax rate is below 22 percent gets the overpayment back as a refund, and someone whose top rate is higher owes the rest. After not getting a bonus at all, this is the complaint employees raise most, and one explanation before the check lands settles it.
What is the difference between a discretionary and a nondiscretionary bonus?
A nondiscretionary bonus is one the employee could see coming: you announced it beforehand, attached criteria to it, or calculated it from a formula. A discretionary bonus is one where both the decision to pay and the amount stayed entirely with you until the period was over or nearly over, with no earlier promise behind it. The label matters because a nondiscretionary bonus has to be counted in the regular rate that sets a nonexempt employee's overtime pay unless a separate statutory exclusion covers it, while a discretionary one can be left out. Very few bonuses genuinely qualify as discretionary.
Does a bonus affect overtime pay?
If it is nondiscretionary and the employee is nonexempt, yes. A nondiscretionary bonus must be included in the regular rate that overtime is calculated from unless a separate statutory exclusion covers it, so an employer paying a production bonus and computing overtime as 1.5 times the base hourly rate is underpaying wages. The DOL names production, attendance, safety, and quality bonuses explicitly. This is the most commonly missed rule in small business payroll and it accrues quietly, week after week.
Is a bonus better than a raise?
They do different jobs. A bonus is a one-time payment that does not carry forward, so it costs you once and can flex with a bad year. A raise is a permanent increase to base pay: it costs you every year afterwards, and it compounds, because future raises are calculated on the higher base. The common mistake is giving a raise for a single strong quarter, which converts a temporary observation into a permanent commitment. Use a raise when someone's market value or scope genuinely changed. Use a bonus for an exceptional result.
How much should a small business pay in bonuses?
It depends far more on what you are trying to achieve than on any benchmark. A year-end bonus works best as a flat sum per person, sized so the business could pay it again next year, and a performance bonus is usually expressed as a percentage of salary that the employer sets. No national average fits a small employer well. The Bureau of Labor Statistics compensation survey for June 2026 shows private employers spending $1.33 for every hour worked on nonproduction bonuses, or 2.8 percent of total compensation, which works as a budgeting anchor rather than as a target. Affordability is the more useful question anyway: a bonus you could not fund in a weak quarter is a liability rather than an incentive, and the damage from skipping one you announced outruns any benefit from having offered it.
Do bonuses count toward overtime, gross pay, and taxes?
Yes to all three, with a nuance. A bonus is part of gross pay for the period it is paid in. It is subject to income tax withholding, Social Security, and Medicare, exactly as salary is. And if it is nondiscretionary and the employee is nonexempt, it also enters the regular rate that overtime is calculated from, unless a separate statutory exclusion covers it. The one thing a bonus is not is an expense outside your payroll: it costs you the amount you paid plus your matching share of FICA, which is around 7.65 percent on top.
Can I take back a bonus if an employee leaves?
Only if you agreed that in advance and in writing, and even then it is jurisdiction-dependent. The typical case is a signing bonus with a clawback: if the employee leaves within a defined period, they repay some or all of it. That must be documented at the time of the offer, not asserted afterwards. And be aware of an ironic consequence: when a company policy or bargaining agreement attaches a clawback to a signing bonus, the payment can no longer be treated as a gift, so it has to be counted in the regular rate when you work out overtime.
Should I pay a holiday bonus every year?
Understand what you are creating before you decide. A holiday bonus paid three years running becomes an expectation, even though the overtime rules can still treat a regular holiday gift as a gift (29 CFR 778.212(c)), and the year you skip it will be experienced as a pay cut rather than as the absence of a windfall. That may still be worth it. But decide deliberately rather than drifting into it, and if you want to preserve genuine flexibility, say clearly and in writing each year that the bonus is discretionary and not a commitment for future years.
