Overtime pay is taxed as ordinary income, and on your W-2 it isn’t broken out separately. Every dollar of overtime rolls into Box 1 with your regular wages, and every dollar of federal tax withheld from those overtime checks rolls into Box 2. What changed recently is the back end: for tax years 2025 through 2028, a new federal deduction lets many hourly workers write off the premium portion of their overtime when they file, which can pull real money back at tax time even though nothing about the W-2 itself looks different.
Where Overtime Appears on Your W-2
Your W-2 has no dedicated line for overtime. All wages, including the extra premium you earned for hours over 40, land in Box 1 (Wages, tips, other compensation) alongside your base pay.1Internal Revenue Service. Treasury, IRS Provide Guidance for Individuals Who Received Tips or Overtime During Tax Year 2025 Box 2 reports the total federal income tax your employer withheld across the year, combining the tax pulled from regular checks and overtime checks into one figure.
Social Security wages appear in Box 3, and Medicare wages appear in Box 5. These figures often differ from Box 1 because pre-tax deductions like 401(k) contributions and health premiums reduce income-tax wages but still count for FICA. If your earnings crossed the annual Social Security wage cap, Box 3 will show the cap while Box 5 shows your full Medicare-taxable pay.
Some employers voluntarily list overtime amounts in Box 14, which is a catch-all for informational items, or send a separate statement. Neither is required. If you need to know your exact overtime totals for the year, your pay stubs are the reliable record.
Why Overtime Paychecks Feel More Heavily Taxed
The IRS treats overtime dollars the same as regular dollars for income tax purposes. The reason overtime checks look disproportionately taxed is the way payroll withholding works, not the underlying rate.
Most employers use the annualized method laid out in IRS Publication 15-T.2Internal Revenue Service. Publication 15-T (2026), Federal Income Tax Withholding Methods The software takes a single paycheck, multiplies it by the number of pay periods in a year, and withholds as though you’ll earn that amount every week. Earn $2,000 in a normal week and the system assumes $104,000 a year. Earn $3,000 in an overtime week and it assumes $156,000 a year, then withholds at the higher rate. For workers who only pick up overtime occasionally, that assumption is wrong, and too much tax comes out during the heavy week.
Other employers treat overtime as supplemental wages and withhold federal income tax at a flat 22%, regardless of your regular bracket. If total supplemental wages (overtime, bonuses, commissions combined) top $1 million in a year, the rate on the excess jumps to 37%.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide – Section: 7. Supplemental Wages For most hourly workers, the flat 22% method tracks closer to actual liability than the annualized method during overtime-heavy weeks. Ask your payroll department which method they use if you can’t tell from your stubs.
Social Security and Medicare on Overtime
FICA taxes hit overtime at the same flat rates as regular pay. Your employer withholds 6.2% for Social Security and 1.45% for Medicare on every paycheck, and matches those amounts.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
Social Security has an annual wage cap. For 2026, the 6.2% stops once total wages reach $184,500.5Social Security Administration. Contribution and Benefit Base Any overtime you earn after crossing that line is exempt from Social Security withholding.
Medicare has no cap. An additional 0.9% Medicare surtax applies once your wages exceed $200,000 in a calendar year. Your employer must start withholding it the pay period you cross that line, regardless of your filing status.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax The actual threshold where you owe the surtax depends on filing status: $200,000 single, $250,000 married filing jointly, $125,000 married filing separately. You reconcile any difference when you file.
The New Overtime Deduction for 2025 Through 2028
The One Big Beautiful Bill Act created a federal deduction for qualified overtime compensation, in effect for tax years 2025 through 2028.7Internal Revenue Service. One, Big, Beautiful Bill Act: Tax Deductions for Working Americans and Seniors It covers only the premium portion of overtime — the extra “half” in time-and-a-half — not the full overtime check. If your regular rate is $30 and your overtime rate is $45, the deductible amount is the $15 premium for each overtime hour, not the full $45.
The deduction is above the line. It reduces adjusted gross income whether you itemize or take the standard deduction, and you claim it on Schedule 1-A (Form 1040) when you file. Overtime is still withheld from your paycheck during the year as usual; the tax break shows up at filing.
Who Qualifies
The deduction is limited to workers covered by and not exempt from the overtime requirements of the Fair Labor Standards Act. You must be a non-exempt employee receiving overtime pay required under the FLSA for hours worked beyond 40 in a workweek. Salaried employees classified as exempt do not qualify, even if their employer voluntarily pays them overtime or a collective bargaining agreement provides for it.8Internal Revenue Service. Questions and Answers About the New Deduction for Qualified Overtime Compensation Married taxpayers must file jointly to claim it.
Limits and Phaseout
The maximum deduction is $12,500 per return, or $25,000 for married filing jointly. It phases out for taxpayers with modified adjusted gross income above $150,000 ($300,000 joint).1Internal Revenue Service. Treasury, IRS Provide Guidance for Individuals Who Received Tips or Overtime During Tax Year 2025 Well above those thresholds, the benefit shrinks or disappears.
Figuring the Deductible Amount
Because the W-2 doesn’t separately report overtime, you calculate the deductible premium yourself. IRS Notice 2025-69 accepts several reasonable methods depending on how your pay is reported.9Internal Revenue Service. Notice 2025-69 – Guidance for Individual Taxpayers Who Received Qualified Tips or Qualified Overtime Compensation in 2025 The common cases:
- If your pay stub breaks out the overtime premium separately, use that figure.
- If your pay stub shows total overtime pay at time-and-a-half but not the premium alone, take one-third of the total. Total overtime pay of $6,000 means a deductible premium of $2,000.
- If overtime is paid at double time or another rate above time-and-a-half, only the FLSA-required “half” portion qualifies. For double time, that’s one-half of the total premium.
Hold on to your pay stubs and any employer statements. Those records back up the deduction if the IRS follows up.
Adjusting Your W-4 So Less Is Withheld
Starting in 2026, you can update Form W-4 to account for the expected deduction. Worksheet 4(b) on the W-4 walks you through entering the amount, which then goes on line 4(b) of the form itself.10Internal Revenue Service. Form W-4 (2026) Employee’s Withholding Certificate That reduces the income figure your employer uses to calculate withholding, so more of the deduction shows up in your paycheck instead of waiting for a refund. The IRS Tax Withholding Estimator at irs.gov/W4App can help you land on a realistic number, especially if your overtime hours swing week to week.
What Happens When You File
Everything reconciles on Form 1040. Total income from all sources is added up, adjustments and deductions are applied, and tax is calculated on the result using the progressive rate structure — only income within each bracket is taxed at that bracket’s rate.11Internal Revenue Service. Federal Income Tax Rates and Brackets
If your employer overwithheld during heavy overtime weeks, which is common under the annualized method, the excess comes back as a refund. The new deduction adds to that effect: Box 1 still shows the full overtime, but Schedule 1-A knocks the premium amount off your taxable income, lowering the final bill below what was already withheld.
The reverse can happen if you have multiple jobs or significant non-wage income. To avoid an underpayment penalty, your withholding plus any estimated payments must equal at least the lesser of 90% of your current-year tax or 100% of last year’s tax. If last year’s adjusted gross income exceeded $150,000, that 100% threshold rises to 110%.12Office of the Law Revision Counsel. 26 U.S.C. 6654 – Failure by Individual to Pay Estimated Income Tax
Getting Your Withholding Closer to Right
The most useful step is keeping your W-4 current. If you regularly work overtime, run the IRS Tax Withholding Estimator with your recent pay stubs in hand so the tool has your year-to-date earnings.10Internal Revenue Service. Form W-4 (2026) Employee’s Withholding Certificate The estimator handles fluctuating income and will suggest an adjustment that avoids large overwithholding without setting you up to owe in April.
Knowing your employer’s method helps too. Workers in the 10% or 12% bracket whose overtime is being withheld at the flat 22% supplemental rate can adjust their W-4 to reduce withholding. Workers in the 24% bracket or above whose overtime is taxed at 22% supplemental may need to add withholding to avoid a bill at filing time.
