Overtime is not taxed at a special rate. The IRS treats overtime wages exactly like regular wages: they stack on top of your normal pay and are taxed at your ordinary marginal rate in the 10%–37% federal brackets. There is no separate "overtime tax," and the extra half of time-and-a-half does not get punished with its own bracket.
So why does an overtime check feel lighter than you expected? Because a bigger paycheck makes payroll withhold like you earn that much all year. On a $25-an-hour job, 10 overtime hours a week can look like a 22% combined bite per extra dollar on that check — mostly ordinary income tax plus FICA — and the difference is settled when you file. The examples below use 2026 figures so you can see both pieces.
Ask around any break room and you will hear some version of this: "I stopped picking up overtime because taxes take half of it." The frustration is real, but the tax code is not. Nowhere in the IRS rules is there a line for overtime income. Your W-2 reports one number, total wages, and every dollar in it — base pay, overtime premium, shift differentials — is taxed the same way.
That means overtime dollars are taxed at whatever your marginal rate is: the rate on your last dollar of income. A single filer in 2026 pays 10% on taxable income up to $12,400, 12% up to $50,400, 22% up to $105,700, then 24%, 32%, 35%, and 37% above that, after the $16,100 standard deduction. If your regular pay already puts you in the 22% bracket, each overtime dollar loses 22 cents to federal income tax — the same as a raise, not more. If you are in the 12% bracket, it loses 12 cents.
Where the myth gets its fuel is the gap between withholding and actual tax. Withholding is payroll's per-check estimate, and a fat overtime check can make that estimate jump even when your real bracket does not. Sections 2 and 3 separate those two numbers, because only one of them is final — and it is not the one on your stub.
Your employer does not know your annual income in advance, so payroll annualizes every check: it multiplies this period's pay by your number of pay periods, runs that implied annual salary through the brackets, then divides back down. Work a heavy week and the system assumes, for withholding purposes, that you earn that heavy pay all year.
Here is the mechanical version for someone paid biweekly. Ten overtime hours at time-and-a-half raise a paycheck from $2,000 to $2,750. Payroll annualizes $2,750 to $71,500 instead of $52,000, computes the tax on $71,500, and withholds one twenty-sixth of it. The withholding rate on the whole check rises, and the incremental withholding on just the overtime slice can reach into the low 20s once FICA is added — which reads, on a stub, like overtime being taxed harder.
Two things keep this honest. First, bonuses are different: bonuses and commissions are supplemental wages, usually withheld at a flat 22% (37% above $1 million in a year). Overtime paid inside a regular paycheck is not supplemental pay — it rides your normal W-4 and the standard tables. If your stub seems to show a flat 22% skim on overtime, your employer is most likely using the aggregate method on a separate check, and that still reconciles at filing time. A one-off spike also corrects itself: later checks annualize lower, and any true excess returns as a refund. The tax withholding calculator shows this per-paycheck split for your own salary.
Let us put real numbers on it. You earn $25 an hour, work 40 regular hours plus 10 overtime hours every week, and live in Texas so there is no state income tax. Regular pay is $1,000 a week; overtime at $37.50 adds $375, for $1,375 a week and $71,500 a year. Without the overtime you would earn $52,000.
Federal income tax first. On $52,000, taxable income after the $16,100 standard deduction is $35,900, and the tax is about $4,060. On $71,500, taxable income is $55,400 and the tax is about $6,900. The $19,500 of overtime pay therefore adds $2,840 of federal tax over the year — roughly 14.6 cents per overtime dollar, a blend of the 12% bracket and a small slice at 22%. Not half. Not 40%. About a seventh, because at this income your overtime straddles two low brackets.
Now the paycheck view, because that is where the sticker shock lives. A biweekly check without overtime is $2,000 and carries about $156 of federal withholding. The same check with two weeks of overtime is $2,750 and carries about $265. The extra $750 of gross pay loses about $109 to federal withholding (that same 14.6%) plus $57.38 to FICA at 7.65%, leaving roughly $583 of the $750 as take-home. The overtime hour you sold for $37.50 nets about $29 before any state tax — a real haircut, but a far cry from "the government took it all." Run your own rate and hours in the overtime pay calculator, then check the after-tax side with the take-home pay calculator.
Income tax gets the attention, but FICA is the steadier bite. Social Security takes 6.2% of wages up to $184,500 in 2026, and Medicare takes 1.45% on every dollar with no cap, plus 0.9% extra on wages over $200,000. Overtime gets no exemption from any of it: the hour that pays $37.50 loses $2.33 to Social Security and $0.54 to Medicare before income tax is even considered, and your employer matches the 7.65% on their side of the ledger.
One quirk works in high earners' favor late in the year. Once your year-to-date wages pass $184,500, the Social Security line stops entirely — so December overtime is suddenly 6.2% more valuable per dollar than January overtime. Past $200,000 the extra 0.9% Medicare tax claws a little of that back. Neither change shows up in your hourly rate; both show up on the stub, which is why two identical overtime weeks in March and November can net different amounts.
State tax is the swing factor. In Texas, Florida, and the other no-income-tax states, the example above is the whole story: federal plus FICA. In California or New York, the same overtime dollars also feed state withholding under that state's tables, and a heavy check can lose several more points there. The job and the hours are identical — the ZIP code decides how much of the premium survives. If you are weighing a transfer or a remote role, compare net overtime pay with your gross-to-net estimate by state, not just the posted hourly rate.
Because withholding annualizes each check, spiky overtime tends to over-withhold, not under-withhold. Work three brutal months and nine normal ones, and payroll spent those three months withholding as if the brutal pace were permanent. The IRS settles up when you file: withholding above your real bill comes back as a refund. That is also why a bigger refund after a heavy-overtime year is not a bonus — it is your own wages completing a round trip.
If the pattern repeats every year, trim it at the source. Line 4(c) of Form W-4 lets you adjust withholding; the usual fix for chronic over-withholding is the opposite direction — reviewing Step 3 credits and Step 4 entries so less is held from each regular check — but do it with the IRS Tax Withholding Estimator in front of you, not by feel. Aim to land near zero owed either way, and stay inside the safe harbor (at least 90% of this year's tax, or 100% of last year's, 110% if your income topped $150,000) so no underpayment penalty is in play. A rough year-end projection with the federal income tax calculator takes two minutes and beats guessing in April.
Finally, keep the boring paperwork: every pay stub showing overtime hours and the overtime rate, plus your final W-2. If a stub ever prices an overtime hour at straight time, the weekly total is where you prove it — federal law computes overtime per workweek, and hours cannot be averaged across two weeks to make the premium disappear. Catch the error in the month it happens and payroll can fix it with a phone call.
No. Overtime wages are taxed at your ordinary marginal rate, the same as regular wages — there is no separate overtime tax or overtime bracket. Overtime can push some dollars into your next bracket, and withholding on a big check often looks steeper because payroll annualizes it, but at filing time overtime is taxed exactly like salary.
Payroll annualizes each paycheck, so a heavy overtime check is withheld as if you earned that amount all year. On top of that, FICA takes a flat 7.65% (6.2% Social Security up to $184,500 plus 1.45% Medicare) from every overtime dollar. If the overtime was temporary, the over-withholding typically returns as a larger refund when you file.
No. The flat 22% federal withholding (37% above $1 million a year) applies to supplemental wages like bonuses and commissions. Overtime paid in a regular paycheck is withheld through the normal W-4 tables instead. Some employers pay overtime on a separate check using the aggregate method, which can look like a flat skim — either way, it reconciles on your tax return.
Yes. Overtime pay is wages for FICA purposes: 6.2% Social Security on wages up to $184,500 in 2026 and 1.45% Medicare on all wages, plus 0.9% more Medicare above $200,000. Your employer matches the 7.65%. Once you pass the Social Security wage base, that 6.2% stops for the rest of the year.
Only the portion that was over-withheld relative to your real annual tax bill. If overtime withholding exceeded what you owe at your actual marginal rate, the difference comes back as a refund. If overtime genuinely moved you into a higher bracket for the year, that part is real tax, not over-withholding. An annual W-4 checkup keeps the two from getting confused.
