Take-Home-Paycheck Calculator

How the take-home paycheck calculator estimates federal income tax withholding across six tax years

This calculator does not maintain a separate set of tax brackets. Instead, it reuses the site's own US federal income tax calculator directly, feeding it your gross annual pay, filing status, and selected tax year, and taking its result as the federal income tax component of your paycheck, which makes this page double as a federal income tax rate calculator in its own right, walking through the real marginal-bracket math for the year and filing status you pick rather than applying a single flat rate. Pick any year from 2026 back to 2020 (2021 is intentionally skipped): each year has its own standard deduction and marginal bracket schedule, since both are adjusted for inflation most years, and 2025's standard deduction reflects the One Big Beautiful Bill Act's mid-year increase rather than the original, lower figure some older sources still show.

Three filing statuses are supported: Single, Married Filing Jointly, and Head of Household. Head of Household is not simply Single with a bigger deduction bolted on; its bracket thresholds are set independently each year, and in several years its highest bracket begins a small, specific amount below where Single's does, a real rounding quirk in how the IRS indexes each filing status for inflation, not an error in this calculator. Reusing one shared federal income tax estimator across all of this site's tools, rather than re-implementing the brackets here, means a single source of truth for every year's figures, so this tool and the standalone federal income tax estimator can never quietly disagree on the same income and filing status. That shared source of truth is also what makes this a dependable paycheck tax calculator in its own right, not two half-answers that could quietly drift apart.

How FICA payroll tax works, and why it never changes with the tax year

FICA is a separate tax system from federal income tax, funding Social Security and Medicare specifically. It has no standard deduction and no progressive brackets; instead it applies flat rates to your wages, with one important twist for Social Security: a wage cap. Unlike the federal brackets above, FICA here always uses the current wage base and rate, regardless of which tax year you pick for the federal comparison; this site tracks a full history of the federal bracket schedule, not a year-by-year Social Security wage base. Together, the two pieces make this a complete FICA calculator: a social security tax calculator for the capped 6.2% portion, and a medicare tax calculator for the uncapped 1.45% portion.

Worked example at $80,000. Take a Single filer earning $80,000 a year, paid bi-weekly (26 times a year), with no state rate or deductions entered. Social Security tax is 6.2% of wages, and $80,000 is well under the current wage base of $184,500, so the full amount is taxed: $80,000 × 0.062 = $4,960. Medicare tax is 1.45% of all wages with no cap: $80,000 × 0.0145 = $1,160. Since $80,000 is below the $200,000 Additional Medicare Tax threshold for a Single filer, no additional Medicare tax applies. Add 2026's federal income tax on $80,000 to these two FICA amounts, and the total is subtracted from $80,000 to get an annual net pay, which is then divided by 26 pay periods to get a per-paycheck figure, the same math a biweekly paycheck calculator uses for any bi-weekly payroll. This is also the same arithmetic behind a plain Florida paycheck calculator, since Florida is one of the states that charges no state income tax at all, along with Texas and Washington, so leaving the state field blank already gives the right answer for a Florida paycheck.

The Social Security wage base cap, explained with a $250,000 example

Unlike Medicare, Social Security tax stops applying once your wages for the year exceed the annual wage base, currently $184,500. This is a real, published payroll rule, not an approximation: every dollar of wages up to $184,500 is taxed at 6.2%, and every dollar above it is simply not subject to Social Security tax at all for that year.

Worked example at $250,000. Take a Single filer earning $250,000 a year, paid monthly. Social Security tax is calculated on the lesser of the actual wages and the wage base: min($250,000, $184,500) × 6.2% = $184,500 × 0.062 = $11,439, not $250,000 × 0.062, which would overstate the tax by taxing wages the cap already excludes. Medicare tax has no such cap, so it applies to the full amount: $250,000 × 0.0145 = $3,625. Because $250,000 is above the $200,000 single-filer threshold, the Additional Medicare Tax also applies, but only to the wages above that threshold: ($250,000 − $200,000) × 0.9% = $50,000 × 0.009 = $450. Together, the two Medicare components on this income are $3,625 + $450 = $4,075, on top of the capped Social Security tax of $11,439.

A full worked example, with a 401(k), health insurance, and a state tax rate

The examples above leave every optional field blank. Here is the same idea with all of them filled in, working as a paycheck calculator with 401k contributions and health insurance both included, which is closer to what a real payroll deductions calculator produces. Take a Single filer with $100,000 in gross annual pay, paid bi-weekly, contributing 10% of pay to a traditional 401(k), paying $50 per paycheck for health insurance, and entering a 5% flat state tax rate.

Health insurance is a Section 125 deduction, so it comes off first, from every wage base at once: $50 × 26 pay periods = $1,300 a year, leaving $98,700 in wages for Social Security and Medicare. The 401(k) comes off next, but only from the wages federal and state tax are calculated on, never from the FICA wages already set: 10% of the full $100,000 gross is $10,000, leaving $88,700 as the wage base for both federal income tax and the flat state rate. Social Security tax is $98,700 × 6.2% = $6,119.40, and Medicare is $98,700 × 1.45% = $1,431.15, both calculated on the health-insurance- reduced figure, not the 401(k)-reduced one. The flat state tax is 5% of $88,700, or $4,435, and federal income tax is calculated on that same $88,700 using the 2026 bracket schedule above. Add every tax together, then subtract the 401(k), health insurance, and any post-tax deduction from gross pay to reach the final net figure, exactly what the calculator above does automatically and shows in the gross-to-net breakdown chart.

What this estimate still leaves out

A few gaps are worth stating plainly about this take home paycheck calculator. First, state income tax still uses a flat rate you supply, not a real bracket table. Each US state writes its own rules, some flat, some progressive, some nonexistent, from a Texas paycheck calculator that needs no state field at all, to a California paycheck calculator, a New York paycheck calculator, a New Jersey paycheck calculator, a Pennsylvania paycheck calculator, or a Virginia paycheck calculator, each with real bracket structures a single flat-rate field can only approximate; a single formula cannot fairly represent all fifty at once. Think of the state field here as a paycheck calculator by state that you configure yourself: enter whichever flat rate actually matches where you live, rather than trusting a guess made on your behalf. Second, the 401(k) percent field has no annual dollar cap. The IRS sets a real yearly contribution limit for a 401(k), and that limit changes almost every year the same way the tax brackets above do; verifying every year of that separate limit was outside the research this calculator's brackets are drawn from, so a very high percentage entered here is not capped at the real legal limit, only calculated literally. If your employer offers a 401(k), use that calculator to check your contribution against the actual annual limit. Third, this is not a bonus tax calculator: every dollar of gross pay is taxed the same way, through the ordinary annual brackets above, rather than the flat 22% federal rate many employers apply to a one-time bonus under the IRS supplemental-wage rules, so a bonus estimate run through this tool will not match a paycheck withheld using that separate flat-rate method. Fourth, there is no field for an hourly wage: if that is all you know, this still works as a plain hourly paycheck calculator once you do one extra step, multiply your hourly rate by your weekly hours and by 52 to get the annual gross pay this tool expects, then pick the matching pay frequency above.

For a deeper look at the difference between what shows up on the gross-pay line of an offer letter and what actually lands in your bank account, the gross pay vs. net pay guide on this site's blog walks through the full calculation by hand, including how to calculate biweekly pay from an annual salary. The salary calculator is a useful companion for comparing pay frequencies, and the US federal income tax calculator is the place to see the federal bracket breakdown for your income on its own, in more detail than fits in the summary here. Used as a take-home paycheck calculator, a net salary calculator, or a simple take home pay estimator before accepting a job offer, the same three numbers, federal tax, FICA, and whatever state rate applies, are the ones worth checking first.
