For most workers in the United States, somewhere between 20% and 35% of a paycheck goes to taxes. The guaranteed floor is 7.65% for Social Security and Medicare. Everything above that depends on how much you earn, what you put on your W-4, your filing status, and where you live and work. So the honest answer to what percentage of taxes is taken out of your paycheck is that there is no single number, but the pieces are predictable once you break them apart.
The 7.65% You’ll Always Pay: FICA
Social Security and Medicare taxes, together called FICA, are flat and don’t care about your W-4. Social Security is 6.2% of your gross wages up to an annual wage base of $184,500 for 2026.1Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Once your year-to-date wages cross that threshold, the 6.2% stops for the rest of the calendar year. If you earn under it, you pay on every dollar.
Medicare is 1.45% of all wages with no cap.2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates High earners pay an Additional Medicare Tax of 0.9% on wages above certain thresholds: $200,000 for single and head-of-household filers, $250,000 for married filing jointly, and $125,000 for married filing separately.3Internal Revenue Service. Questions and Answers for the Additional Medicare Tax Employers start withholding the extra 0.9% once your wages pass $200,000, regardless of filing status, and any difference is reconciled on your return.
Add 6.2% and 1.45% and you get 7.65%. That’s the minimum that comes out of every paycheck before income tax even enters the picture.
Federal Income Tax: The Variable Piece
Federal income tax is where the percentage swings widely. Your employer doesn’t apply a rate. Instead, they estimate your annual tax bill based on the information on your Form W-4, then spread that estimate across your paychecks using the IRS withholding tables in Publication 15-T.4Internal Revenue Service. Publication 15-T (2026), Federal Income Tax Withholding Methods Your filing status, dependent credits, and any extra withholding you requested all feed into the calculation.5Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate
What comes out of your check reflects your effective tax rate, not your marginal rate. The marginal rate is what applies to your last dollar. The effective rate is your total tax divided by your total income. Because the federal system is progressive, your first dollars are taxed at 10%, the next tier at 12%, and so on, so someone whose top bracket is 22% often has an effective rate closer to 12% or 13% once the standard deduction and lower brackets are counted. The percentage taken from your paycheck is almost always lower than the bracket you think you’re in.
The 2026 Standard Deduction
The standard deduction is subtracted from your gross wages before the brackets apply, so it directly shrinks the taxable base your employer uses. For 2026:6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill
- Single or married filing separately: $16,100
- Married filing jointly: $32,200
- Head of household: $24,150
A single filer earning $60,000 doesn’t pay federal income tax on the first $16,100. Only $43,900 runs through the brackets.

What This Looks Like in Practice
Take a single filer earning $80,000 in gross wages. Subtract the $16,100 standard deduction and taxable income is $63,900. The first $12,400 is taxed at 10%, the next $38,000 at 12%, and the remaining $13,500 at 22%. The total federal income tax comes to about $8,930, roughly 11.2% of gross wages. Add the 7.65% for FICA and you’re at about 18.8% in federal taxes before any state or local tax touches the check.
State and Local Taxes
Where you work can add several percentage points to the total. State income tax rates run from zero in states that impose no income tax to over 13% at the top of the most aggressive state brackets. Eight states currently levy no individual income tax. Among the rest, most use progressive brackets similar to the federal model, and a handful apply a single flat rate.
Some cities and counties impose their own income or payroll taxes on top of the state’s, typically in the 1% to 2.5% range, though a few reach close to 4%. Not every state permits local income taxes, so this line item depends entirely on your work location. A worker in a high-tax state with a local income tax could see 5% to 10% or more withheld for state and local combined. A worker in a no-income-tax state keeps all of that.
Pre-Tax Deductions Shrink the Percentage
Pre-tax deductions come out of your gross pay before income tax is calculated. They lower the number your employer plugs into the withholding tables, which lowers the federal tax that comes out. The main ones:
- Traditional 401(k) contributions, up to $24,500 in 2026, plus an $8,000 catch-up if you’re 50 or older. Every dollar reduces federal taxable income dollar-for-dollar, though it does not reduce FICA.7Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500
- Employer-sponsored health insurance premiums, almost always taken pre-tax through a Section 125 plan, which reduces both income tax and FICA.
- HSA contributions through payroll, up to $4,400 for self-only coverage or $8,750 for family coverage in 2026 with a qualifying high-deductible plan. These reduce both income tax and FICA.8Internal Revenue Service. IRS Notice 2026-05, 2026 HSA Contribution Limits
- FSA contributions, which are exempt from federal income tax and employment taxes.9Internal Revenue Service. Publication 969 (2025), Health Savings Accounts and Other Tax-Favored Health Plans
Someone earning $80,000 who contributes $10,000 to a 401(k) and $3,000 to an HSA has a federal taxable base of $67,000 for withholding purposes. The tables treat that worker as though they earn $67,000, and the percentage of gross pay going to federal income tax drops noticeably.
Bonuses Are Withheld Differently
Bonuses, commissions, overtime, and severance are supplemental wages, and your employer can withhold on them separately from your regular paycheck. The common approach is a flat 22% federal rate on the entire bonus, with no reference to your W-4.10Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide The alternative aggregate method adds the bonus to that period’s regular pay and calculates withholding on the combined total, which often withholds more because the inflated amount pushes part of it into a higher bracket for that paycheck.
Supplemental wages above $1 million in a calendar year are withheld at a mandatory 37% flat rate on the excess, regardless of your W-4. FICA still applies at 6.2% and 1.45%. A bonus check typically loses about 30% or more to combined taxes, but that’s withholding, not final tax. If your actual effective rate for the year is lower, you get the difference back on your return.
Checking and Adjusting Your Withholding
The IRS Tax Withholding Estimator at irs.gov is the tool to use for a reality check.11Internal Revenue Service. Pay As You Go, So You Won’t Owe: A Guide to Withholding, Estimated Taxes and Ways to Avoid the Estimated Tax Penalty Enter your income, deductions, and credits, and it will tell you whether you’re on track for a refund, a balance due, or close to even, and suggest specific W-4 changes to close any gap.
Run it at least once a year, and again after any major life change: marriage, divorce, a new baby, buying a house, a side business, or a significant raise. Each can shift your tax liability enough to throw off withholding. Submit a new W-4 to payroll when you want a change; your employer must put it into effect no later than the start of the first payroll period ending on or after 30 days from the date they receive it.12Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
Then check your next couple of pay stubs. Each one breaks out federal income tax, Social Security, and Medicare separately. Compare against what the estimator projected. Getting the numbers close means you keep more money during the year instead of over-withholding, and you avoid a surprise bill in April from under-withholding.
