How Is Overtime Pay Taxed? The Truth About Your Extra Hours

There's a persistent myth that overtime pay is taxed at a higher rate than regular wages. It isn't — but the paycheck on a week with heavy overtime often looks like more was taken out. Understanding why requires understanding how employers calculate withholding, why that withholding can spike on a large check, and what actually happens at tax filing time.

The short version: the IRS taxes overtime as ordinary income at your marginal rate. Whether that paycheck looks right depends entirely on how your employer calculates withholding for unusually large paychecks.

Overtime Pay Basics: Who Gets It and How Much

Under the Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5× their regular rate for hours worked beyond 40 in a workweek. At $20/hour, you'd earn $30/hour for hours 41 and beyond. This time-and-a-half rate is set by federal law; some states (California, for example) also require overtime for hours beyond 8 in a single day, regardless of the weekly total.

The FLSA defines "regular rate of pay" broadly — it generally includes all compensation except certain exclusions like gifts, vacation pay, and expense reimbursements. If you receive non-discretionary bonuses, those must usually be folded into the regular rate calculation, which can make the overtime calculation more complex than simply multiplying your hourly wage by 1.5.

Salaried employees classified as exempt are not entitled to overtime pay under FLSA, regardless of how many hours they work. The 2026 FLSA salary exemption threshold is $684/week ($35,568/year), though many states have higher thresholds.

How the IRS Actually Taxes Overtime

The IRS does not have a special "overtime tax rate." Overtime income is simply income — it's added to your other wages and taxed at your marginal rate, using the exact same progressive bracket structure as all your other compensation.

For 2026, federal income tax brackets for a single filer are:

Taxable income	Federal rate
$0 – $11,925	10%
$11,926 – $48,475	12%
$48,476 – $103,350	22%
$103,351 – $197,300	24%
$197,301 – $250,525	32%
$250,526 – $626,350	35%
Over $626,350	37%

If your regular wages put you in the 22% bracket, overtime dollars that don't push you into a higher bracket are also taxed at 22% — same as your last dollar of regular pay. Only overtime that pushes you past a bracket threshold faces a higher rate on those excess dollars.

Why Your Overtime Paycheck Looks Overtaxed

Here's where the myth comes from. When your employer calculates withholding for a paycheck, they typically use the "annualized" method: they take your gross pay for that period, multiply it by the number of pay periods in a year, look up the withholding for that annualized amount, and then divide by the number of pay periods to get this period's withholding.

On a normal bi-weekly paycheck of $2,000, the employer annualizes to $52,000 and withholds accordingly. But on a week where you earned $2,000 in regular pay and an additional $600 in overtime, the employer sees $2,600 — annualizes that to $67,600 — and withholds at a rate appropriate for $67,600 of income. That rate is higher than it needs to be for your actual full-year income, because the overtime isn't happening every two weeks.

The result: your overtime paycheck has more withheld than necessary. You're not paying extra taxes — you're prepaying taxes at an inflated rate, and you'll get the excess back when you file your return.

Concrete Example: Regular Week vs Overtime Week

Employee: Single, no allowances, $25/hour, bi-weekly pay schedule, state with no income tax

Pay period	Hours	Gross pay	Fed withheld	FICA	Net pay
Regular (80 hrs)	80	$2,000	~$175	$153	~$1,672
With 20 OT hrs	80+20	$2,750	~$343	$210	~$2,197
Gross increase	—	+$750	+$168	+$57	+$525

The $750 in overtime gross pay produced $525 in additional net pay — a 70% take-home rate. The remaining 30% went to increased withholding ($168 federal + $57 FICA). Note that some of the $168 in extra federal withholding may come back as a refund if the annualized calculation over-withheld — FICA does not refund.

FICA Taxes and the Social Security Wage Base

Social Security tax (6.2%) applies to wages up to the annual wage base ($176,100 in 2026). Once your total wages for the year exceed that amount, Social Security tax stops. This is particularly relevant for employees who work significant overtime and may hit the cap mid-year — their net overtime checks later in the year will be noticeably larger because the 6.2% Social Security tax no longer applies.

Medicare tax (1.45%) has no wage cap. High earners also face an Additional Medicare Tax of 0.9% on wages above $200,000 for single filers ($250,000 for married filing jointly). This additional 0.9% applies to the employee's share only — employers don't match it — and is assessed at filing time if it wasn't fully withheld from paychecks.

How to Avoid Surprises at Tax Time

If you work frequent overtime, your cumulative withholding for the year should roughly match your actual tax liability. Problems arise in a few specific scenarios:

• You had a year with unusually high overtime. Your employer withheld at rates based on your normal pay, and now your actual income is significantly higher than it anticipated. You may owe more than expected.
• You have multiple jobs. Each employer withholds based only on the wages they pay, without knowing about your other income. Combined income may push you into a higher bracket that no single employer's withholding accounts for.
• Your overtime is lumpy. Some months heavy, some months none. The annualized withholding method smooths this imperfectly.

The fix for all three: use the IRS Withholding Estimator, enter your expected full-year income including overtime, and adjust Step 4(c) on your W-4 to add extra withholding if needed. A small extra withholding amount each paycheck prevents a large April tax bill.

Does Working More Overtime Ever "Not Pay"?

This is another common concern — that working more eventually costs more in taxes than you gain. It's not how progressive taxation works. Under a marginal bracket system, higher rates only apply to the dollars above each threshold, not to all your income. You are never, in the U.S. federal system, worse off from earning more money. Each additional dollar of overtime always increases your after-tax take-home — the marginal rate on that dollar is never 100% or above.

The misconception arises because a paycheck that annualizes higher can have higher withholding — but that's a withholding timing issue, not a tax liability issue. Your actual tax bill is settled at filing, not on each paycheck.
