Is Overtime Taxed More?

Updated

The short answer: no, overtime is not taxed at a higher rate. A dollar earned as overtime is taxed exactly like a dollar of regular pay. What people notice is that a bigger-than-usual paycheck often has a bigger share withheld — and that is a withholding quirk, not a tax on overtime.

Why a big paycheck looks over-taxed

Employers calculate federal income tax withholding by annualising each paycheck: they assume every check this year will be the size of this one, work out the tax on that inflated annual figure, and withhold a proportional slice.

If you normally earn $1,500 a week but this week you earned $2,400 with overtime, payroll briefly treats you as a $2,400 × 52 = $124,800 earner and withholds at that higher bracket — just for that check. Social Security (6.2%) and Medicare (1.45%) are flat percentages, so those rise in exact proportion and nothing unusual happens there.

It evens out

Your actual income tax is settled once a year when you file a return. It is based on your real total income, not on any single paycheck. If the annualising method caused too much to be withheld from your overtime weeks, the excess comes back as a larger refund (or a smaller amount owed). You do not lose it.

The trade-off is timing: over-withholding is an interest-free loan to the government until you file. If you regularly work overtime and want more in each check instead of a bigger refund, you can adjust your Form W-4 — but do it carefully, because under-withholding can leave you with a bill.

The bonus method (supplemental wages)

Overtime paid in your normal paycheck is withheld with your normal wages. But if overtime or a bonus is paid separately, the employer may use the IRS supplemental wage method: a flat 22% federal withholding on amounts up to $1 million. That flat 22% can be higher or lower than your real marginal rate, which again squares up at tax time.

The 2025–2028 federal overtime deduction

A 2025 federal law created a temporary deduction for qualified overtime pay for tax years 2025 through 2028. In outline:

  • It applies to the "half" premium portion of FLSA overtime — the extra 0.5× on top of your regular rate, not the whole time-and-a-half amount.
  • The deduction is capped (reported figures are $12,500 for a single filer and $25,000 for a joint return) and phases out at higher incomes.
  • It is an income-tax deduction you claim on your return. It does not exempt overtime from Social Security or Medicare, and it does not change what your employer withholds unless IRS guidance says otherwise.
  • Your employer reports qualifying overtime so you can claim it.

Because this provision is new, temporary, and subject to IRS guidance, confirm the current rules and amounts with the IRS or a tax professional before relying on them.

What actually reduces your overtime take-home

  • Bracket creep within the year: extra income can push part of your earnings into a higher marginal bracket — but only the amount above each threshold is taxed at the higher rate.
  • Percentage-based deductions: a 401(k) set at 6% takes 6% of the bigger check too (this is saving, not tax).
  • Wage garnishments: some are calculated as a percentage of disposable earnings, so they scale with the check.
