Federal withholding is not a flat share of your pay. Publication 15-T tells an employer to annualise the pay period, subtract a fixed W-4 amount — $12,900 filing jointly, $8,600 otherwise — and look the result up in a bracket schedule that starts at 0% and climbs to 37%. The annual figure is then divided back over the pay periods, so a raise mid-year changes every remaining paycheck. Social Security and Medicare work differently: 6.2% and 1.45% of gross pay, with no allowance and no brackets. Social Security stops once the year's wages pass the wage base, $184,500 in 2026; Medicare never stops, and adds 0.9% above $200,000 a year. This calculator spreads both evenly across the year rather than front-loading Social Security the way real payroll does, so the annual total is right and a single high-earning paycheck is not. State tax is a single rate you enter. That is exactly right for the nine states with no wage income tax, where the rate is 0, and for the flat-rate states, where the statute names one number. It is wrong for states with graduated brackets — California, New York, Ohio and the rest — because no single rate can stand in for a schedule. Withholding is also not your tax bill. It is an estimate the employer pays in on your behalf; the return in April settles the difference.
The brackets, the $12,900 and $8,600 W-4 amounts and the dollar rounding are IRS Publication 15-T for 2026. The wage base and the FICA rates are Publication 15 and the Social Security Administration.
A single percentage fits the nine states with no wage income tax and the states with a statutory flat rate. Where the state has graduated brackets, local surtaxes or its own deductions, the figure here is an approximation and nothing more.
The employer pays in what the W-4 and the table say. Credits for children, a second job, itemised deductions or other income all move the real liability, and the return settles it.
The deduction field lowers federal and state taxable wages but not Social Security and Medicare wages, which is how a 401(k) deferral behaves. Health premiums under a Section 125 plan lower FICA wages too, so this calculator understates their benefit.
My marginal rate is 22%, so 22% of my paycheck goes to federal tax.
The 22% applies only to the part of the annual wage above that bracket's floor. On $1,000 a week the whole federal withholding is $78, about 7.8% of gross.
Social Security is 6.2% of everything I earn.
It stops at the wage base, $184,500 in 2026, so the maximum an employee pays is $11,439. Medicare has no ceiling and adds 0.9% above $200,000.
My 401(k) contribution cuts every tax on my paycheck.
A 401(k) deferral lowers federal and state taxable wages only. Social Security and Medicare are still charged on the full gross.
I live in California, so I entered 9.3% as my state rate.
California uses graduated brackets, and a single rate cannot represent them at any income. Treat the state figure as a rough estimate unless your state has a statutory flat rate.
| Weekly gross, single filer | Federal withholding | Social Security + Medicare | Take-home |
|---|---|---|---|
| $600 | $30 | $45.90 | $524.10 |
| $800 | $54 | $61.20 | $684.80 |
| $1,000 | $78 | $76.50 | $845.50 |
| $1,200 | $102 | $91.80 | $1,006.20 |
| $1,400 | $138 | $107.10 | $1,154.90 |
For a single filer earning $1,000 a week in 2026, $78 goes to federal withholding, $62.00 to Social Security and $14.50 to Medicare, leaving $845.50 before any state tax. The federal share rises faster than pay because the brackets are graduated.
IRS Publication 15-T annualises the pay period, subtracts $12,900 for joint filers or $8,600 otherwise, and applies the year's bracket schedule. The annual tax is then divided by the number of pay periods and may be rounded to the nearest dollar.
It is $184,500, up from $176,100 in 2025. Once your wages for the year pass it, no further Social Security tax is withheld, capping the employee share at $11,439.
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. For a paycheck in any of them the state rate here is 0.
The W-4 has fields this calculator leaves out — dependent credits, other income, extra withholding and the two-job checkbox — and each moves the federal figure. Local taxes, unemployment insurance in a few states and post-tax deductions also come off the real stub.
No. A 401(k) deferral lowers wages for federal and state income tax but not for Social Security and Medicare. Health premiums paid through a Section 125 plan do lower FICA wages, which this calculator does not model.
