Calculate how much federal, state, and FICA withholding taxes will deduct from your standard and overtime earnings.
A common misconception is that overtime pay is permanently taxed at a higher rate than regular pay. In reality, all of your earnings—regular wages and overtime—are grouped together at the end of the year and taxed under standard marginal tax brackets. However, the withholding from your specific paycheck may look significantly higher.
If you track earnings inside Excel or Google Sheets (assuming cell A1 contains gross overtime wages, cell B1 has your federal tax rate, cell C1 has state tax, and cell D1 has standard FICA tax of 7.65%):
=A1 - (A1 * (B1/100 + C1/100 + D1/100)) (Estimated Overtime Net Payout)
This table summarizes how withholding taxes apply to regular wages compared to supplemental overtime wages across standard income segments:
| Tax Type | Regular Pay Withholding | Supplemental Overtime Withholding |
|---|---|---|
| Federal Income Tax | Marginal Bracket Rates (10% to 37%) | Standard Bracket Rates OR Flat 22% Rate |
| State Income Tax | Marginal Bracket Rates (0% to 13.3%) | Standard Bracket Rates OR Flat Supplemental Rates |
| Social Security (FICA) | Flat 6.2% Rate (up to wage limits) | Flat 6.2% Rate |
| Medicare (FICA) | Flat 1.45% Rate | Flat 1.45% Rate |
Answers to common questions about calculating pay raises and salary increases.
Technically, no. Your overtime income is taxed at the exact same rates as your regular income at the end of the year. However, because overtime pay can push you into a higher marginal tax bracket or trigger higher paycheck withholding rules, your employer may withhold tax from that specific check at a higher rate.
Payroll software typically calculates your tax withholding by multiplying that single paycheck's total by the number of pay periods in a year. If you have a high overtime check, the software calculates taxes as if you make that high amount all year, resulting in an artificially inflated withholding tax rate.
The IRS allows employers to withhold federal tax from supplemental wages (such as overtime, bonuses, and commissions) at a flat withholding rate of 22% instead of using standard marginal tax bracket calculations.
Like standard wages, overtime is subject to Federal Income Tax, State Income Tax (where applicable), Local Income Tax, and FICA taxes (6.2% for Social Security and 1.45% for Medicare).
Yes. If your payroll software withheld too much tax from your overtime checks during the year, the overpayment will be reconciled when you file your annual tax return, resulting in a larger tax refund.
You can adjust your tax withholding by updating your Form W-4 with your employer. However, adjusting withholdings to compensate for irregular overtime is complex and can accidentally lead to owing taxes at the end of the year.
The aggregate withholding method combines your regular wages and supplemental overtime wages into a single payment, then calculates withholding taxes on the total sum using standard bracket calculations for that pay period.
