Between 20% and 35% of a typical paycheck goes to taxes, with 7.65% as the fixed floor that every W-2 worker pays. What percentage of taxes is taken out of your paycheck depends on how much you earn, your filing status, what you put on your W-4, and the state and city where you work. There is no single rate, because several taxes hit your wages at once and each follows its own rules.
The 7.65% Everyone Pays
The most predictable piece of your paycheck is FICA, which funds Social Security and Medicare. These are flat-rate taxes that apply the same way no matter what you claimed on your W-4.
Social Security tax is 6.2% of gross wages, matched by another 6.2% from your employer. 1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates The 6.2% only applies up to an annual wage base. For 2026 that base is $184,500. 2Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Once year-to-date earnings cross that line, Social Security withholding stops for the rest of the year. If you earn $184,500 or less, you pay the 6.2% on every paycheck.
Medicare tax is 1.45% of all wages with no cap. 1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates High earners pay an Additional Medicare Tax of 0.9% on wages above $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 begin withholding the extra 0.9% once your wages cross $200,000, regardless of filing status, and any reconciliation happens on your return.
Add it up and most workers pay a combined 7.65% in FICA (6.2% plus 1.45%) on every dollar earned. That is the floor before income tax enters the picture.
Federal Income Tax: The Variable Piece
Federal income tax is where the percentage swings. Your employer does not apply one rate. Instead, they estimate your annual tax bill from the information on your Form W-4 and spread that estimate evenly across your paychecks. 4Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate
The W-4 tells payroll your filing status, whether you are claiming the child tax credit or other dependent credits, and whether you want extra tax withheld. Payroll plugs that data into the withholding tables in IRS Publication 15-T to calculate the per-paycheck deduction. 5Internal Revenue Service. Publication 15-T (2026), Federal Income Tax Withholding Methods
The percentage withheld reflects your effective tax rate, not your marginal rate. The marginal rate is what you pay on your last dollar. The effective rate is total tax divided by total taxable income. Because federal brackets are progressive, the first slice is taxed at 10%, the next at 12%, and so on. Someone whose top bracket is 22% might land near an 11% or 13% effective rate once the standard deduction and lower brackets are counted. That is why the percentage leaving your paycheck is almost always lower than the bracket you think you are in.
2026 Brackets and Standard Deduction
The standard deduction is subtracted from your income before any bracket applies, so it directly shrinks the withheld amount. 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 does not pay income tax on all $60,000. The first $16,100 comes off the top, and only $43,900 runs through the brackets.
The seven federal brackets for 2026 are:
- 10%: Up to $12,400 (single) / $24,800 (joint)
- 12%: $12,401 to $50,400 (single) / $24,801 to $100,800 (joint)
- 22%: $50,401 to $105,700 (single) / $100,801 to $211,400 (joint)
- 24%: $105,701 to $201,775 (single) / $211,401 to $403,550 (joint)
- 32%: $201,776 to $256,225 (single) / $403,551 to $512,450 (joint)
- 35%: $256,226 to $640,600 (single) / $512,451 to $768,700 (joint)
- 37%: Over $640,600 (single) / Over $768,700 (joint)
Walk through a single filer earning $80,000. Subtract $16,100 for the standard deduction, leaving $63,900 in taxable income. The first $12,400 is taxed at 10%, the next $38,000 at 12%, and the remaining $13,500 at 22%. Federal income tax works out to roughly $8,930, or about 11.2% of gross wages. Add the 7.65% for FICA and the total federal bite is near 18.8% before any state or local tax.
State and Local Taxes Change the Total
Where you work can move the final percentage by several points. State income tax rates range from zero in states with no income tax to over 13% in the highest brackets of the most aggressive states. Eight states currently levy no individual income tax. Among the rest, most use progressive brackets, and a handful apply a single flat rate to all wages.
Some cities and counties add their own income or payroll tax on top. Local rates typically fall between 1% and 2.5%, though a few run higher. Not every state allows local income taxes, so whether you see one depends on your work location.
The combined effect matters. A worker in a high-tax state with a local tax can see 5% to 10% or more withheld for state and local taxes on top of federal. A worker in a no-income-tax state keeps all of that.
Pre-Tax Deductions Lower the Percentage
Pre-tax deductions come out of gross pay before income tax is calculated, which shrinks the number the withholding tables run against. The most common ones:
- Traditional 401(k) contributions. For 2026 you can defer up to $24,500, with another $8,000 catch-up if you are 50 or older. Every dollar reduces federal taxable income dollar-for-dollar.7Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500
- Employer-sponsored health insurance premiums, which are almost always deducted pre-tax through a Section 125 cafeteria plan and reduce both income tax and FICA.
- Health Savings Account contributions, up to $4,400 for self-only coverage or $8,750 for family coverage in 2026 when paired with a qualifying high-deductible plan. Payroll contributions reduce both income tax and FICA.8Internal Revenue Service. IRS Notice 2026-05, 2026 HSA Contribution Limits
- Flexible Spending Account 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 puts $10,000 into a 401(k) and $3,000 into an HSA has a federal taxable base of $67,000. Withholding treats them as a $67,000 earner, and the effective percentage of gross pay going to federal income tax drops noticeably.
One nuance: traditional 401(k) contributions reduce income tax but not FICA. Health premiums, HSA contributions through payroll, and FSA contributions reduce both.
Why Bonuses Look Different
Bonuses, commissions, overtime, and severance are supplemental wages, and your employer can withhold federal income tax on them differently than on regular pay. The most common approach is a flat 22% applied to the bonus, ignoring your W-4. 10Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide FICA still applies at the standard 7.65%, so a bonus check often loses close to 30% to combined federal taxes before any state tax.
That withholding is an estimate, not a final tax. If your effective rate for the year is lower than 22%, you get the difference back as a refund.
Self-Employment Doubles the FICA Side
Self-employed workers have no employer paying the matching half of FICA, so they pay both. The self-employment tax rate is 15.3%, covering 12.4% for Social Security and 2.9% for Medicare. 11Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion stops at the same $184,500 wage base, and the 0.9% Additional Medicare Tax kicks in at the same thresholds. You can deduct half of your self-employment tax when calculating adjusted gross income, which lowers your income tax. 12Internal Revenue Service. Topic No. 554, Self-Employment Tax
Because nothing is being withheld for you, quarterly estimated tax payments are due April 15, June 15, September 15, and January 15 of the following year. 13Internal Revenue Service. Estimated Tax – Frequently Asked Questions If you also hold a W-2 job, one shortcut is raising paycheck withholding on your W-4 to cover the self-employment tax too.
Checking and Adjusting What Comes Out
The IRS Tax Withholding Estimator at irs.gov is the best tool for seeing whether your current percentage is on track. 14Internal 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 tells you whether you are heading for a refund, a balance due, or close to even, plus the specific W-4 changes to close any gap.
Run it at least once a year, and again after a major change: marriage, divorce, a new baby, buying a house, starting a side business, or a big raise. Any of these can shift your tax liability enough to throw off your withholding. Submit a new W-4 to payroll. Your employer must put the update into effect no later than the start of the first payroll period ending on or after 30 days from the date they receive it. 15Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
Then watch the next couple of pay stubs. Each one breaks out federal income tax, Social Security, and Medicare separately. Compare those numbers to what the estimator projected. Getting the percentage dialed in means more money in your pocket during the year and no surprise bill in April.
