Overtime Pay and Taxes: How Much Will You Actually Keep?

Many workers believe overtime is taxed at a higher rate than regular pay. While your overtime paycheck may look like more was taken out in taxes, the reality is more nuanced. Understanding how withholding works on overtime will help you see the full picture.

Is Overtime Taxed Differently?

No. Overtime pay is taxed at the same rates as regular income. The confusion arises because of how payroll withholding works. When you receive a larger paycheck due to overtime, your employer's payroll system withholds taxes as if you earned that higher amount every pay period, which can result in higher withholding.

Why Your Overtime Check Looks Smaller

• Payroll systems annualize each paycheck to estimate your annual income
• A bigger paycheck makes the system assume you earn more all year
• This pushes more of the check into a higher withholding bracket
• The excess withholding is returned to you as a refund when you file

FICA Taxes on Overtime

Social Security tax (6.2%) and Medicare tax (1.45%) apply to overtime pay just like regular wages. If your total earnings exceed the Social Security wage base ($176,100 in 2025), overtime earned above that threshold is not subject to Social Security tax but still owes Medicare tax.

How to Estimate Your True Overtime Take-Home

• Determine your marginal federal tax bracket
• Add your state income tax rate
• Add 7.65% for FICA (or 1.45% if above Social Security wage base)
• Your take-home is roughly overtime pay minus those combined percentages

For most workers in the 22% federal bracket with a 5% state tax, overtime take-home is roughly 65% of gross overtime pay after federal, state, and FICA taxes.

Why Overtime Feels Like a Bigger Tax Hit

Overtime is taxed at your regular federal income tax rate — there is no separate 'overtime bracket.' The perception that overtime is taxed higher comes from how supplemental pay is withheld, not how it is ultimately taxed. Many employers use the aggregate method for overtime withholding, where the pay is added to a regular paycheck and withheld as if that check's gross were the annual rate. A worker whose regular bi-weekly check is $2,000 but who earns $3,500 on an overtime-heavy check has the $3,500 annualized to $91,000 for withholding — triggering the 22% bracket assumption even though the actual annual salary is closer to $52,000.

The 25% Supplemental Flat Rate (2025)

For 2025, IRS Publication 15 prescribes a 22% flat federal withholding rate on supplemental wages (bonuses, severance, commissions, and overtime paid separately from regular wages) up to $1 million. Above $1 million of supplemental wages in a single year, the rate jumps to 37%. The flat rate is simple but often over-withholds for workers below the 22% marginal bracket. The aggregate method over-withholds differently — in either case the excess is recovered at filing via a refund.

FLSA Time-and-a-Half Rules

• Federal Fair Labor Standards Act: non-exempt workers get 1.5× regular rate for hours above 40 per workweek
• State laws may be stricter — California: daily overtime above 8 hours AND 2× (double time) above 12 hours
• Exempt employees (salaried executives, professionals, administrators earning above $58,656 as of 2025) are NOT entitled to overtime regardless of hours worked
• Regular rate includes non-discretionary bonuses and shift premiums — not just base wage — for computing the 1.5× multiplier

The Actual Tax Cost of an Overtime Dollar

For a single filer in the 22% federal bracket earning approximately $75,000, each overtime dollar carries 22% federal, 6.2% Social Security, 1.45% Medicare, plus state tax ranging from 0% (Texas, Florida, Tennessee) to 13.3% (California top bracket). Total marginal cost lands between 29.65% and 42.95% of each overtime dollar. The net take-home on an overtime dollar is therefore between 57 cents and 70 cents — meaningful but not the '50%' figure workers often report after looking at their pay stubs.

The Over-Withholding Refund Cycle

A worker whose regular withholding is correct but who earns $8,000 in overtime over the year typically sees $1,760 of supplemental withholding (22% × $8,000) against an actual incremental tax liability closer to $1,200-$1,500 depending on bracket. The excess is recovered as part of the annual refund in the following April. Workers who prefer the money in-paycheck can file a Form W-4 with Step 4(b) deductions claimed to reduce withholding — but only if their annual tax liability genuinely supports the adjustment.

Overtime and Means-Tested Credits

The Earned Income Tax Credit and refundable portion of the Child Tax Credit phase in with earned income and then phase out. Overtime can push a household into the phase-out range — for example, the 2025 EITC phase-out begins at $22,720 of earned income for single filers with one qualifying child, meaning additional overtime above that level reduces the credit by 15.98 cents per dollar. For borderline-eligible workers, this can produce a marginal effective tax rate above 40% on the specific dollars crossing the phase-out threshold.

Key Takeaways

• Overtime at time-and-a-half is taxed at the same federal rates as regular wages — there is no 'overtime tax rate.'
• The reason overtime feels over-taxed: withholding tables annualize the larger check as if it were your new weekly pace.
• Any 'overtime penalty' evens out at tax filing — the final liability depends on annual income, not per-paycheck withholding.
• Recent bipartisan proposals to exempt overtime from federal tax remain proposals as of 2025 and are not enacted law.
• FICA (7.65%) does apply fully to overtime wages until the SS wage base of $176,100 is met for the year.

Common Mistakes to Avoid

• Declining overtime because of 'tax penalty' myths — the marginal math virtually always nets positive cash.
• Not filing a Form 843 claim when FICA was over-withheld from multiple employers past the $176,100 cap.
• Ignoring the reality that overtime income can bump you into a higher bracket only on the overtime dollars themselves.
• Forgetting that state income tax also applies to overtime — high-OT earners in NY/CA see meaningfully higher net rates.
• Assuming 'double time' or 'holiday pay' is tax-exempt — it's all ordinary W-2 wages.

Angelo's Overtime Week: Why $642 Extra Became $428 Net

Angelo F. is a single filer in West Virginia earning $56,000 as a maintenance technician, paid $26.92/hour. In one extraordinarily busy week he worked 16 hours of overtime at time-and-a-half. Gross overtime was $645.99; net deposit change was roughly $428. Overtime is not taxed at a higher rate — but it can look that way on the paystub.

• Regular hourly rate: $26.92 — Overtime rate (1.5×): $40.38
• Overtime gross: 16 hours × $40.38 = $646.08
• Federal withholding shift: overtime push moves that week's annualized income estimate up, withholding temporarily higher at 22% bracket assumption = $142.14
• FICA 7.65%: $49.43
• West Virginia state tax at ~5%: $32.30
• Net overtime pay: $422.21 — 65.4% of gross
• Year-end reconciliation: if Angelo's true marginal is 12%, he recovers ~$64 of the 'extra' withholding at tax time

The myth that 'overtime is taxed higher' comes from the withholding algorithm, not from the tax code. Payroll software annualizes each paycheck to estimate an annual rate, so a big overtime week temporarily projects a higher-bracket rate for that single check. The IRS reconciles this at filing. A federal proposal to make overtime fully tax-free was discussed in 2025 but has not been enacted — until it is, overtime income is taxed identically to regular wages.

Case Study: Stellan P. Works 12 Hours of Overtime

Stellan P., HoH in South Carolina at $62,000 base, worked 12 hours of overtime at time-and-a-half and saw the overtime check withholding look punishing. Overtime is not taxed at a special rate - it is simply more wages in the same pay period, pushed through cumulative withholding tables.

• Regular hourly rate: $29.81. Overtime rate: $44.72 per hour.
• Overtime earnings: 12 hours x $44.72 = $536.64.
• Federal withholding on the combined check rises because the annualized paycheck is projected higher - but the actual marginal rate is still 22%.
• FICA: 7.65% of $536.64 = $41.05.
• Net from overtime: roughly $380 after federal, FICA, and SC state withholding.

The paystub makes overtime look heavily taxed because withholding tables annualize the current check. At year-end, Stellan's actual tax on the overtime is 22% federal plus 7.65% FICA plus state - exactly the same rate that applies to his regular wages at that bracket. Any over-withholding refunds at filing. Publication 15-T explains the percentage-method formula employers use.
