Federal taxes alone usually take between 20% and 30% of a paycheck through a mix of income tax, Social Security, and Medicare withholding, and once state and local taxes are added the total can climb past 35%. How much the government takes from your paycheck depends on what you earn, your filing status, where you live and work, and which pre-tax benefits you’ve signed up for through your employer. Someone earning $50,000 in a no-income-tax state with a healthy 401(k) contribution keeps a very different share than someone at the same salary in a high-tax city with no retirement deferrals.
Federal Income Tax Comes Out in Layers
The federal income tax is progressive, which means your income is taxed in slices instead of all at one rate. There are seven brackets in 2026: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Only the dollars that fall within a given bracket are taxed at that bracket’s rate. Crossing into the 22% bracket does not raise the tax on your whole salary; it only raises the rate on the income above the 12% threshold.
For a single filer in 2026, the 10% bracket covers the first $12,400 of taxable income, 12% runs up to $50,400, and 22% runs up to $107,450. The 24%, 32%, and 35% brackets stack above that, with the 37% top rate kicking in above roughly $651,000. Married couples filing jointly get wider brackets: the 10% rate covers the first $24,800 and the 12% rate reaches $100,800, so a household earning the same total as a single filer often owes less federal income tax.1Internal Revenue Service.

The Standard Deduction Shields a Chunk of Pay
Before the bracket math applies, the standard deduction removes a portion of income from taxation. In 2026 that’s $16,100 for single filers or married filing separately, $32,200 for married filing jointly, and $24,150 for head of household.
This matters more than most people realize. A single person earning $50,000 doesn’t owe tax on all $50,000. After subtracting the $16,100 standard deduction, taxable income drops to $33,900. The first $12,400 is taxed at 10% ($1,240), and the remaining $21,500 at 12% ($2,580), for a federal income tax bill of about $3,820. That’s an effective rate of roughly 7.6% on gross pay, well below the 12% marginal bracket.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Social Security and Medicare Take Another 7.65%
Every paycheck also loses a flat 7.65% to Social Security and Medicare, together called FICA. Your employer pays a matching 7.65% that never shows up on your pay stub. The split is 6.2% for Social Security and 1.45% for Medicare, and unlike income tax there is no standard deduction to soften the first dollar earned.2Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax On a $50,000 salary that works out to $3,100 for Social Security and $725 for Medicare, or $3,825 in FICA alone.
Social Security tax stops once your earnings for the year pass $184,500 in 2026, after which the 6.2% withholding disappears from your paychecks for the rest of the calendar year.3Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security If you’ve ever noticed a jump in take-home pay late in the year, that is likely why. Medicare has no cap. High earners also pay an Additional Medicare Tax of 0.9% on wages above $200,000 for single filers or $250,000 for married couples filing jointly.4Internal Revenue Service. Topic No 560, Additional Medicare Tax
If you work two jobs and your combined wages exceed the Social Security cap, each employer withholds independently because neither knows what the other is paying. The result is over-withholding, which you can claim back as a credit on your federal return.5Internal Revenue Service. Topic No 608, Excess Social Security and RRTA Tax Withheld
State and Local Taxes Depend on Where You Live and Work
Most states impose their own income tax, with structures that vary widely. Some mirror the federal progressive setup, others apply a single flat rate, and nine states tax no wage income at all. Top marginal state rates range from under 3% to over 13%, so location alone can swing take-home pay by thousands of dollars a year.
Local taxes add another layer. Thousands of cities and counties levy payroll or income taxes, typically between 1% and 2.5% of gross wages, with some charging a small flat fee per pay period instead. Employers track these based on both company location and where the employee actually works, so two coworkers can have different withholdings if they sit in different offices or work remotely from different jurisdictions.
Living in One State, Working in Another
If you live in one state and work in another, you could technically owe tax in both. Many neighboring states have reciprocal agreements that let you owe tax only to the state where you live. Without such an agreement, you’ll generally file in the work state, pay there, and claim a credit on your home-state return to avoid being taxed twice. Skipping the work-state filing can bring penalties even if your home state ultimately gets all the tax.
State Disability and Paid Leave Deductions
A growing number of states require payroll deductions for disability insurance or paid family leave programs. These typically run between 0.2% and 1.3% of wages, with rates and wage caps that vary by state and sometimes by employer size. They won’t appear as “income tax” on your stub, but they still reduce take-home pay.
Pre-Tax Deductions Shrink the Bite
Certain paycheck deductions come out before taxes are calculated, lowering your income tax and, in most cases, your FICA. Many of these run through a Section 125 cafeteria plan covering benefits like health insurance premiums, dependent care, and health savings account contributions.6Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans
Retirement contributions are the biggest lever most workers have. In 2026 you can contribute up to $24,500 to a traditional 401(k), with the full amount coming out of your paycheck before income tax is calculated. Workers aged 50 and older can add another $8,000.7Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If you’re in the 22% bracket and contribute $10,000, that’s roughly $2,200 less in federal income tax, plus reduced FICA depending on how the plan is structured.
Health savings accounts also lower taxable income, with 2026 limits of $4,400 for individual coverage and $8,750 for family coverage.8Internal Revenue Service. 2026 Inflation Adjusted Amounts for Health Savings Accounts Not every deduction works this way. A Roth 401(k) contribution comes out of after-tax pay and does not reduce your current tax bill. Check your pay stub to see which deductions are labeled pre-tax and which are not.
Why Bonuses Look Overtaxed
Bonuses, commissions, and other supplemental pay often appear to be taxed more heavily than regular wages. That is true for withholding, but not for your actual tax liability. The IRS gives employers two options for withholding on standalone bonus checks of $1 million or less: a flat 22% rate, or the aggregate method that lumps the bonus into your regular paycheck and withholds based on the combined amount. Either approach often withholds more than your true effective rate. Supplemental wages above $1 million in a calendar year are withheld at 37%, matching the top federal income tax rate.9Internal Revenue Service. Publication 15 (2026), Employers Tax Guide
Withholding is not the same as final tax. If 22% withheld on a $5,000 bonus exceeds what you actually owe based on your full-year income, the difference comes back as part of your refund. Bonuses are taxed as ordinary income at your regular rate when you file.
Self-Employment Changes the Math
If you work as an independent contractor or freelancer, no employer is splitting FICA with you. You pay the full 15.3% yourself: 12.4% for Social Security and 2.9% for Medicare.10Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The tax applies to 92.35% of net earnings rather than the full amount, which accounts for employees not paying FICA on the employer’s share.11Internal Revenue Service. Topic No 554, Self-Employment Tax You can also deduct the employer-equivalent half when calculating adjusted gross income, which reduces your income tax.
Nothing is withheld from the payments you receive. You’re responsible for quarterly estimated tax payments to the IRS, due in April, June, September, and January of the following year.12Internal Revenue Service. Estimated Tax – Individuals Miss them and you’ll face underpayment penalties on top of the tax. First-time freelancers often get caught here, spending the full invoice amount and then facing a five-figure bill the following April.
Getting Your Withholding Right
The amount withheld each pay period is based on what you tell your employer on IRS Form W-4.13Internal Revenue Service. About Form W-4, Employees Withholding Certificate Filing status, income from a second job, and credits you expect for dependents all feed the calculation. Head of household filers get a bigger standard deduction ($24,150 versus $16,100 for single filers), so withholding on the same salary is lower.
Withholding is only an estimate spread across pay periods. You can end up with too much withheld (a refund) or too little (a balance due and possible penalties). You generally avoid the underpayment penalty if your total payments through withholding and estimated tax reach at least 90% of what you owe for the current year, or 100% of last year’s tax liability, whichever is less.14Internal Revenue Service.
