Start with gross overtime pay
For many covered, non-exempt US employees, federal law requires at least time-and-a-half for hours over 40 in a workweek. At a $25 regular rate, 8 overtime hours at 1.5× create $300 of gross overtime pay: 8 × $25 × 1.5.
Your employer may have a more generous agreement, and state rules can differ. Not every worker is covered by the same overtime rules, so confirm your employment arrangement if the calculation does not match your pay stub.
Is overtime taxed differently?
Overtime is generally wage income. The IRS describes overtime as supplemental wages, but employers can treat it as regular wages in some payroll situations. If it is separately identified, an employer may use a flat federal withholding method or combine it with regular wages for the pay period. That affects what is withheld now; your final income-tax liability depends on your full-year return.
A simple after-tax estimate
Suppose $300 of overtime is paid and you use a 22% federal withholding assumption plus 7.65% for Social Security and Medicare. The simple estimate is $211.05 after those two deductions. State and local taxes, benefits, wage caps, W-4 settings and payroll timing can change the actual result.
| Item | Amount |
|---|---|
| 8 hours × $25 × 1.5 | $300.00 gross overtime |
| 22% federal estimate | -$66.00 |
| 7.65% payroll-tax estimate | -$22.95 |
| Estimated overtime after those taxes | $211.05 |
Why the paycheck can look wrong
A high withholding amount does not automatically mean overtime has a permanent special tax rate. A one-off larger paycheck can be withheld using payroll-period assumptions that differ from your full-year tax position. Use the IRS withholding estimator and your year-to-date pay stub when you need a more personal projection.
Use the extra income deliberately
Overtime is often variable, so avoid relying on it for permanent recurring bills. It can be especially useful for an emergency fund, high-interest debt, annual expenses or a specific savings goal. Directing part of each overtime payment automatically makes the temporary income more visible in your finances.
