Questions about overtime pay
How do I calculate time and a half?
Multiply your regular hourly rate by 1.5. At $15 an hour, time and a half is $22.50 an hour.
Which hours count as overtime?
Under the federal Fair Labor Standards Act, hours over 40 in a fixed workweek. The Department of Labor says each week stands alone, with no averaging across weeks.
Do some states pay overtime by the day?
Some states do, on top of the federal weekly rule. Check your state's labor department. This calculator uses the federal weekly rule only.
Does a bonus change my overtime rate?
It can. The Department of Labor says nondiscretionary bonuses go into your regular rate, which raises the overtime rate. This calculator uses the one rate you enter.
Is overtime pay tax free?
No. IRS guidance says overtime stays in your gross income, and Social Security and Medicare still apply. For tax years 2025 to 2028 a federal deduction can cover the half of time and a half, up to a cap.
How do I work out that deduction?
Use the no tax on overtime calculator on this site. It applies the cap, the income phase-out and your filing status, and gives an estimate.
