Overtime Calculator 2026

Overtime at 1.5× sounds like a big raise — until the IRS takes its share. At a $25/hr base rate, you keep roughly 70 cents of every overtime dollar after federal income tax and FICA. This calculator shows your real after-tax overtime pay, not just the gross number on your offer.

FLSA Overtime Rules — What You Need to Know

1.5× Rate

After 40 hours in a single workweek, your employer must pay at least 1.5 times your regular hourly rate for every additional hour worked. Some states (e.g. California) require daily overtime after 8 hours.

Who Qualifies

Non-exempt hourly workers automatically qualify. Salaried employees earning under $684 per week ($35,568/year) also qualify for overtime regardless of job title or duties.

Who Doesn't

Exempt employees — executives, administrators, professionals, and some computer workers — are not covered. Independent contractors are also exempt, as overtime is an employment law protection.

Is Overtime Actually Worth It?

Your overtime hour earns 1.5× gross — but taxes are calculated on your full marginal rate, not an average. Enter your hourly rate to see what you actually keep.

$/hr
OT gross / hour$37.50
Federal income tax−$4.50
FICA (7.65%)−$2.87
You keep$30.13
You earn $37.50 in overtime. After taxes, you keep $30.13(80%).

Marginal rate estimate: annualizes your base wage to determine the federal bracket, then applies that bracket rate to each overtime dollar. FICA rate is 7.65% (employee share). State tax uses a flat 5% approximation when enabled.

Frequently Asked Questions

How is overtime calculated?
Under the FLSA, overtime pay is at least 1.5 times your regular hourly rate for all hours worked beyond 40 in a single workweek. Some states have additional daily overtime rules — California, for example, requires 1.5× after 8 hours in a single day. Your workweek is a fixed, recurring 168-hour period; hours don't carry over from week to week.
Are overtime earnings taxed at a higher rate?
Overtime itself isn't taxed at a special rate — it's ordinary income. However, because overtime pushes your total earnings higher, it may move some income into the next federal tax bracket. Only the dollars in the higher bracket are taxed at the higher rate; the rest of your income stays in its original bracket.
Does my employer have to pay overtime?
If you are a non-exempt employee under the FLSA, yes — your employer is legally required to pay overtime for hours over 40 per week. Exempt employees (executive, administrative, and professional roles earning over $35,568/year) are not entitled to overtime. Your classification depends on your actual duties and salary, not just your job title.
Is overtime included in my annual salary for tax purposes?
Yes. Overtime wages are added to your total W-2 wages and taxed as ordinary income on your federal and state tax return. When your employer withholds taxes from your paycheck, they typically use your annualized wages to estimate your bracket — so OT paychecks can have higher withholding. You'll reconcile the exact amount when you file.
Can I refuse overtime?
The FLSA does not prohibit employers from requiring mandatory overtime — employees can be required to work more than 40 hours per week or face disciplinary action, including termination (in at-will employment states). Some states and union contracts provide additional protections, but federal law itself does not give employees the right to refuse overtime.
