The federal income tax withheld from each paycheck is an estimate of what you will owe for the year, divided by the number of pay periods. The percentage withheld typically ranges from about 10% to 22% for most workers, though the statutory brackets run from 10% to 37% on income above certain thresholds. Your W-4 tells your employer how to estimate your annual liability.
2025 federal income tax brackets (single filers)
| Taxable income | Rate |
|---|---|
| Up to $11,925 | 10% |
| $11,926 to $48,475 | 12% |
| $48,476 to $103,350 | 22% |
| $103,351 to $197,300 | 24% |
| $197,301 to $250,525 | 32% |
| $250,526 to $626,350 | 35% |
| Over $626,350 | 37% |
These brackets apply to taxable income after your standard deduction ($15,000 for single filers in 2025, $30,000 for married filing jointly). Bracket thresholds and the standard deduction adjust for inflation each year. Tax rates and limits vary by year; verify current figures at IRS.gov. This is not tax advice.
2025 federal income tax brackets (married filing jointly)
| Taxable income | Rate |
|---|---|
| Up to $23,850 | 10% |
| $23,851 to $96,950 | 12% |
| $96,951 to $206,700 | 22% |
| $206,701 to $394,600 | 24% |
| $394,601 to $501,050 | 32% |
| $501,051 to $751,600 | 35% |
| Over $751,600 | 37% |
Married filing jointly brackets are roughly double the single thresholds at most levels, which is why a married couple often sees less combined withholding per dollar earned than two single filers at the same income.
How withholding is calculated per paycheck
Your employer does not simply apply your marginal rate to each check. Instead, payroll uses IRS Publication 15-T tables or the following annualization method:
- Take your gross pay for the period.
- Subtract any pre-tax deductions (401(k), health insurance, HSA) to arrive at taxable wages for the period.
- Annualize the taxable wages by multiplying by the number of pay periods per year (26 for biweekly, 52 for weekly, etc.).
- Apply the bracket tables to the annualized figure, accounting for your standard deduction and any W-4 adjustments such as dependent credits or additional withholding.
- Divide the resulting estimated annual tax by the number of pay periods to get the per-paycheck withholding amount.
This is why a bonus or commission paid in a single check sometimes appears to be withheld at a higher rate: the annualization step can push estimated annual income into a higher bracket when a large one-time payment is included. Alternatively, supplemental wages (bonuses) are often withheld at a flat 22% federal rate.
Worked example: federal withholding on a $65,000 salary
A single filer earns $65,000 per year, paid biweekly (26 periods), with a $200 biweekly 401(k) contribution. Here is an approximate federal withholding calculation per paycheck:
| Step | Amount |
|---|---|
| Gross pay per period | $2,500.00 |
| Less: pre-tax 401(k) | -$200.00 |
| Taxable wages per period | $2,300.00 |
| Annualized taxable wages (x26) | $59,800 |
| Less: standard deduction (2025) | -$15,000 |
| Taxable income estimate | $44,800 |
| Estimated annual federal tax (bracket calc) | ~$4,866 |
| Per-paycheck federal withholding (/ 26) | ~$187 |
Actual withholding depends on W-4 step 3 credits and any extra withholding you elected. Use the Paycheck Calculator for a full per-paycheck estimate including FICA and state tax.
What percentage does federal tax take?
For a worker earning $50,000 a year as a single filer with no additional adjustments, federal withholding is often in the range of 12 to 15 percent of gross pay, because most of the income sits in the 10% and 12% brackets after the standard deduction. At $100,000, effective withholding often runs 18 to 22%. These are estimates; your actual number depends on your full tax situation. The Paycheck Calculator gives a paycheck-by-paycheck estimate based on your inputs.
How to change how much is withheld
File a new W-4 with your employer. You can claim dependents (which reduces withholding), add a specific dollar amount of extra withholding per period if you want a larger refund or expect extra income, or note multiple jobs. The IRS Tax Withholding Estimator at IRS.gov can help you decide what to put on your W-4. Changing withholding does not change what you owe for the year, only when you pay it.
Common triggers for filing a new W-4: marriage or divorce, the birth of a child, a second job, leaving a job mid-year, a large windfall, or a pattern of owing a large balance or receiving a large refund at filing. Any of those events changes your projected annual liability and may mean your current withholding is off.
Federal withholding vs what you actually owe
Withholding is an estimate, not your final tax bill. At year end, you file a return that calculates actual tax liability based on total income, deductions, and credits. If withholding exceeded the liability, you get a refund. If it fell short, you owe the difference. Large refunds are not free money: they are an interest-free loan to the government. If you reliably receive refunds of more than a few hundred dollars, adjusting your W-4 to lower withholding puts that money in your paycheck instead. The IRS Tax Withholding Estimator at IRS.gov helps you calibrate what to withhold for the rest of the year.
Why is my federal withholding different from my neighbor's?
Filing status (single vs married), W-4 elections, number of jobs in the household, and pre-tax deductions (like a 401(k) contribution that lowers taxable wages) all make withholding personal. Two people earning identical gross wages can have noticeably different federal withholding. See all paycheck deductions for the full picture.
