You do not get taxed more for overtime under federal law. Overtime pay is taxed at the same rates as your regular wages, and starting in 2026 a new federal deduction may let you subtract the overtime premium from your taxable income entirely. The reason overtime checks look heavily taxed is withholding, not the tax rate itself.
Why Your Overtime Check Looks Smaller
Withholding is an estimate, not your final tax bill. Your employer looks at what you earned in a single pay period and projects it across the year to decide how much federal income tax to hold back.1Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate
Pick up a big overtime check and the payroll system treats it as if you earn that inflated amount every week. A $1,500 check in a week where you normally earn $1,000 gets projected as if you make $78,000 a year instead of $52,000. Withholding on that check climbs to match the higher projected salary, so a bigger slice comes out.
Your actual tax bill is calculated once a year when you file. If your total withholding exceeds what you owe, the IRS refunds the difference.2Office of the Law Revision Counsel. 26 USC 6402 – Authority to Make Credits or Refunds The “extra” tax you saw on your overtime check comes back to you, either as a refund or as a credit against what you would otherwise owe.
The IRS also allows employers to treat overtime as supplemental wages and withhold at a flat 22% (or 37% on amounts above $1 million in a calendar year).3Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide Which method your employer uses affects the size of the check, not the size of your yearly tax bill.
How Tax Brackets Actually Apply to Overtime
The federal government uses a progressive tax system: your income is split into segments taxed at increasing marginal rates, which for 2026 run from 10% to 37%.4Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed Moving into a higher bracket only changes the rate on the dollars above the threshold. Your lower-bracket income keeps its lower rate.5Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Say overtime lifts your taxable income from $50,000 to $55,000 as a single filer in 2026. Only about $4,600 of that lands in the 22% bracket. Everything below the $50,400 threshold stays taxed at 10% and 12%. You never take home less overall by earning more.
The New 2026 Overtime Deduction
The One Big Beautiful Bill Act created a new federal deduction for qualified overtime compensation starting in 2026. Workers who receive overtime may deduct the premium portion — the amount that exceeds their regular rate of pay — when they file their federal income tax return.6Internal Revenue Service. How to Take Advantage of No Tax on Tips and Overtime
If your regular rate is $25 per hour and your overtime rate is $37.50, the deductible amount is the $12.50 premium per overtime hour, not the full $37.50. The deduction does not change withholding. Your employer still holds back federal income tax, Social Security, and Medicare on overtime the same way. You claim the benefit on your return, which may produce a larger refund or a smaller balance due.
Where Overtime Really Can Cost You More
Social Security and Medicare
FICA taxes on overtime work a little differently from income tax. Social Security is 6.2% on wages up to $184,500 in 2026, and once you cross that cap you stop paying it on additional earnings.7Social Security Administration. Contribution and Benefit Base For a high earner, overtime hours late in the year can actually carry a lower total tax burden than earlier hours.
Medicare has no wage cap. The base 1.45% rate applies to every dollar of overtime. If your wages exceed $200,000 in a calendar year, your employer must also withhold an additional 0.9% Medicare tax on earnings above that threshold.8Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Workers who put in heavy overtime in physically demanding or seasonal jobs sometimes cross that line without realizing it.
Tax Credit Phase-Outs
Overtime raises your adjusted gross income, and AGI is what the IRS uses to decide whether you qualify for many credits.9Internal Revenue Service. Adjusted Gross Income A higher AGI can shrink or eliminate credits you would otherwise get, which effectively raises your tax bill even though the overtime itself is taxed at the standard rates.
Two credits are especially sensitive:
- The Child Tax Credit is available in full at AGI of $200,000 or less ($400,000 for joint filers) and phases down above those thresholds.10Internal Revenue Service. Child Tax Credit
- The Earned Income Tax Credit phases out at much lower income levels. A single filer with one child, for example, loses the credit entirely once AGI passes roughly $50,000.11Internal Revenue Service. Earned Income and Earned Income Tax Credit (EITC) Tables
In most cases the overtime still comes out ahead of the lost credit, but the net gain is smaller than the gross pay looks. If you rely on the EITC, run the numbers before agreeing to a heavy overtime schedule.
What You Can Do About It
If you work overtime regularly rather than in a one-off busy season, your withholding may be miscalibrated all year. The IRS offers a free Tax Withholding Estimator that lets you enter expected income, including overtime, and shows how to adjust your W-4 so your paycheck matches your real tax liability more closely.12Internal Revenue Service. Tax Withholding Estimator FAQs Too much withheld and you are lending the government money all year; too little and you could owe a balance plus an underpayment penalty at filing.13IRS. Form W-4 (2026) Employee’s Withholding Certificate
Pre-tax retirement contributions are the other lever. Money going into a traditional 401(k) or 403(b) reduces your taxable income dollar for dollar. For 2026, the contribution limit is $24,500, or $32,500 if you are 50 or older, with a higher $11,250 catch-up for workers aged 60 through 63.14Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Traditional IRAs offer a $7,500 limit for 2026 and may be deductible depending on your income and whether you or your spouse has a workplace plan. Sending overtime into a pre-tax account also lowers your AGI, which can preserve eligibility for the credits above.
A Note on State Taxes
All of the above is federal. Most states also tax wages, including overtime, at rates that currently range from 0% in no-income-tax states to over 13% at the highest brackets. Most states with an income tax use progressive brackets that work the same way as the federal system; a handful use a flat rate. Rules vary, so check your state tax agency for how overtime is treated where you live.
