Commission, Bonus & Tipped Pay on Your Pay Stub (2026)

Why Is My Bonus Taxed So Much?

Most people who get a bonus, a commission check, or a big month of declared tips have the same reaction when the stub lands: where did it all go? A $5,000 bonus shows up as roughly $3,200 in the bank, the combined tax line reads closer to 35% of gross than the 22% federal rate they were expecting, and the windfall stops feeling like one.

The reason is a category the IRS calls supplemental wages, which covers bonuses, commissions, overtime, retroactive pay, tips, and a few other one-off payments. They are withheld under their own rules, and the logic is timing rather than punishment: at the moment it cuts the check, payroll has no way of knowing your actual marginal rate for the year, so it applies a flat rate up front. Whatever that estimate gets wrong is squared up when you file, with over-withholding coming back as a refund and under-withholding becoming a balance due. None of it changes the tax you ultimately owe, but it does change what any given pay stub looks like in the meantime.

So the more useful question isn't whether a payment was "taxed too much." It's which withholding method payroll used, whether FICA and state tax were layered on top correctly, and whether your year-to-date totals are tracking toward a refund or a bill.

The Supplemental Wage Withholding Rules

The IRS allows two methods, percentage and aggregate, and the one your employer picks determines how the stub reads.

The percentage method is the simpler of the two. The employer withholds a flat 22% on supplemental wages up to $1 million per recipient per calendar year, and anything above $1 million in a single year is withheld at 37%, the top ordinary bracket. Because that 22% is fixed regardless of your W-4 or your real marginal rate, a $5,000 bonus shows exactly $1,100 of federal income tax withheld. For anyone in the 10% or 12% bracket the flat rate over-withholds and sets up a refund; for anyone above 22% it under-withholds and sets up a balance due.

The aggregate method works the other way. It lumps the supplemental payment in with your regular wages and withholds on the combined total as if that were your normal paycheck. Someone earning $2,000 a week who receives a $5,000 bonus gets a $7,000 check withheld as though they made $7,000 every week, which throws them into a far higher bracket for that one run and produces the steepest withholding of any scenario.

You can usually tell which method was used just by reading the stub. A separate check with a "Bonus" line and a clean 22% federal tax figure is the percentage method; a combined check carrying unusually high federal tax is the aggregate method. When you have a say in it, the percentage method causes fewer paycheck-to-paycheck surprises, though the annual tax works out the same either way.

Beyond Federal: Social Security, Medicare, and State Tax on Supplemental Wages

Social Security and Medicare apply their usual flat rates no matter the wage type: 6.2% for Social Security up to $184,500 in 2026, and 1.45% for Medicare, with an extra 0.9% additional Medicare tax on wages above $200,000. There is no special supplemental FICA rate.

State income tax is where the variation gets wide. Many states set their own flat supplemental rate, so California withholds bonuses at 10.23%, New York at 11.7%, and Georgia at its flat income-tax rate, while a handful require the aggregate method instead. If your bonus tax line looks higher than the federal rate alone would explain, a separate state rule is usually the reason, because states pay no attention to the federal 22%.

For a separately identified supplemental payment, federal withholding may use the applicable IRS supplemental-wage method, while Social Security, Medicare, and any state or local withholding follow their own rules and limits. The deposit therefore depends on the payroll method and location. Withholding is credited on the tax return; it is not necessarily the final tax attributable to the bonus.

Commission Pay on Your Stub

Commission is supplemental wages too, but because it arrives more often than a bonus, it shapes the stub differently depending on the pay schedule. Some employers fold it into every paycheck, some cut it monthly as a separate check, and some pay it quarterly, and each of those choices changes how the tax is calculated.

When commission is combined with a regular paycheck, the aggregate method applies because the commission isn't separately identified. The stub rolls base and commission into one gross figure and withholds federal tax at the combined marginal rate, so even if you see the split spelled out as "Base Pay $2,000 / Commission $1,500," the tax treats it as a single $3,500 check. The practical effect is that heavy weeks are withheld harder than slow ones: an $8,000 commission week spikes the withholding while a $200 week barely moves it, which is why commission earners do better budgeting by the month than by the paycheck.

When commission is paid as its own check, the percentage method applies and the federal line is a flat 22%. It stands alone on the earnings line, the withholding is predictable, and there are fewer surprises at tax time, which is why most commission earners prefer it.

Clawbacks are the one case that looks alarming but isn't. If a sale you were paid on gets canceled, your employer recovers that commission from a later check, and it shows up as a negative earnings line marked "Commission Clawback" or "Chargeback." The 22% federal tax that was withheld comes back alongside it, so a negative federal tax figure on that stub is correct rather than a system error.

Bonus Pay on Your Stub

Bonuses arrive either as separate checks or folded into regular wages. Separate bonus checks generally use the percentage method, so the federal line reads 22% (or 37% in the rare case that your cumulative bonuses top $1 million for the year), while combined checks usually run through the aggregate method and can show higher-than-usual federal withholding. The earnings line might be labeled "Bonus," "Annual Bonus," "Signing Bonus," "Retention Bonus," or "Spot Bonus," and Social Security and Medicare come out normally in every case.

Signing bonuses with clawback provisions are worth reading closely before you accept them. Say you take a $10,000 signing bonus and leave after 18 months, inside a clawback window of 12 to 24 months. The employer can demand repayment of the full gross $10,000, not the net you actually received, because the withheld taxes already belong to the IRS, and recovering them then falls to you through a Claim of Right deduction or a Form 843 on your next return. That clause is far easier to deal with when you understand it at the offer-letter stage than after you've given notice.

Deferred compensation bonuses, often labeled "DC Award" or "Deferred Compensation Payout," fall under IRC §409A and follow a separate reporting path. For W-2 employees, vested-but-deferred amounts usually appear in Box 11 of the W-2 (Nonqualified Plans), with the taxable portion flowing into Box 1 alongside regular wages in the year it's distributed. They generally don't show up on a 1099 or a K-1 for W-2 employees, since those forms cover contractor pay and partnership distributions, which are separate situations. If a deferred-comp line appears on a stub and the reporting path isn't clear, ask payroll to confirm the W-2 treatment.

Tipped Pay on Your Stub

Tipped workers follow their own set of rules, and their stubs look noticeably different from a salaried one because tips count as earned wages. Cash tips are reported by the worker and labeled "Reported Tips" or "Cash Tips," credit card tips run through the employer as "Credit Card Tips" or "Charge Tips," and tip pools show up as "Pooled Tips."

All of it, cash, card, and pool, counts as taxable wages under the IRS tip-reporting rules in Publication 531. (The old Form 4070 was retired in 2024; employees now report through the employer's system or any written record with the same details.) For tax years after 2024 and before 2029, some workers can account for the qualified-tip deduction on an updated Form W-4, but the underlying rule is still not "tax-free tips." Social Security and Medicare generally apply once tips reach $20 or more in a month, and federal income tax withholding depends on the W-4 and the base wages available to withhold from. That last point explains a common sight on tipped stubs, where federal withholding reads zero because the base wage was too small to withhold against, leaving the remaining liability to surface at filing time.

One line you won't find is the FICA Tip Credit, which benefits the employer rather than the worker. It lets the business claim a credit on its corporate return for the employer share of FICA on tips above minimum wage, and it has no effect on your stub.

It pays to reconcile your YTD tip totals against your own daily log at least once a quarter. Credit-card tip data does reach the IRS, but indirectly, through the employer's Forms 941 and W-2 and, where it applies, the establishment's Form 8027 (Employer's Annual Information Return of Tip Income), rather than straight from the card processors. The IRS uses those filings to compare reported tips against industry averages, and a discrepancy can resurface in an audit years later, so a daily tip log, kept on paper or in any of the free apps, gives you the source documents to back up the figure you reported.

What to Expect at Year-End

Because the flat supplemental rate isn't calibrated to any one worker's actual bracket, it tends to miss in both directions. Someone in the 10% or 12% bracket whose bonus was withheld at 22% sees a refund, while someone in the 32% or 35% bracket sees a balance due, and a surprise bill around April 15 is usually that higher-bracket under-withholding catching up.

A bonus that lands in October is a good prompt to run the IRS Tax Withholding Estimator against your year-to-date numbers. If it projects a shortfall, the two practical fixes are adjusting your W-4 to withhold more on the remaining checks, or making a Form 1040-ES estimated payment before January 15 to hold down the underpayment penalty under IRC §6654.

Commission earners on the aggregate method have the opposite problem: heavy over-withholding in big weeks followed by a large spring refund, with the IRS holding that money interest-free in between. Reducing withholding on the W-4, by adding deductions, claiming dependents, or using the Step 4(b) deductions line, moves that cash back into regular paychecks. Either way, the conversation that actually fixes it happens in September or October, not on April 14.
