Federal only — no state or local income tax, and no employer benefit deductions. Social Security stops at the annual wage base; this calculator spreads it evenly rather than showing the mid-year step change.

Estimate only — not tax advice. These figures are a general educational estimate based on federal tax data and the numbers you entered. They are not a tax return, not tax advice, and not a guarantee of your actual tax. They exclude many credits, deductions, phase-outs, state and local taxes, and situation-specific rules. Using this tool does not create a client relationship. For numbers you can rely on, book a free consultation.

How this works

Where the money goes between gross and net

The gap between the salary you agreed and the amount that arrives in your account is rarely explained properly. It is made of two quite different things, and only one of them is genuinely fixed.

The fixed part is FICA. Social Security takes 6.2% of your wages up to an annual ceiling, and Medicare takes 1.45% of everything with no ceiling at all. Your employer quietly matches both. These rates are set in law, they do not depend on your W-4, and there is nothing to optimise — which is why the figures above for Social Security and Medicare are exact rather than estimates. Once your year-to-date wages pass the Social Security ceiling, that 6.2% stops and your take-home rises for the rest of the year.

The variable part is federal withholding, and it is not a tax — it is a prepayment. Your employer estimates what you will owe and sends it to the IRS on your behalf, using the tables in Publication 15-T and whatever you put on your Form W-4. Get that form wrong and you can be over-withheld all year (a large refund, which is your own money returned late) or under-withheld (a bill in April). Nothing about withholding changes the tax you actually owe; it only changes when you pay it.

That distinction is why we label the withholding line above an estimate. We annualise your pay, subtract the standard deduction, and apply the brackets — a reasonable approximation for a straightforward single job. But real withholding also reflects dependents, a second job or a working spouse, additional withholding you requested, and other income you declared. Those adjustments exist precisely because the simple version is often wrong.

If your refund or bill is consistently large in either direction, that is a W-4 problem, not a tax problem, and it is usually a quick fix. The IRS Tax Withholding Estimator is the tool built for that job.

Choosing your state above turns this into a paycheck calculator by state, so you can see take home pay by state rather than federal-only figures.

Questions

Take-home pay, answered

Treat it as an approximation, not a payroll figure. We annualise your pay, subtract the standard deduction for your filing status, and run the result through the tax brackets. Real payroll systems use the percentage-method tables in IRS Publication 15-T together with the specific entries on your Form W-4 — including dependents, multiple-jobs adjustments, extra withholding, and other income. Those can move the number meaningfully in either direction.

Social Security stops once your year-to-date wages pass the annual wage base, so high earners see their take-home rise late in the year. Medicare has no ceiling and continues on every dollar. This calculator spreads the annual figures evenly, so it will not show that mid-year step change.

An Additional Medicare Tax of 0.9% applies to wages above $200,000 for single and head of household filers, $250,000 for married filing jointly, and $125,000 for married filing separately. It is employee-only — there is no employer match. It appears in the breakdown when your figures cross the threshold.

We apply them to the federal income tax estimate only. That is deliberately conservative: 401(k) deferrals reduce income tax but not Social Security and Medicare, while Section 125 health premiums reduce both. Applying them to FICA as well would understate FICA for the most common case.

It is a federal calculator. State income tax varies enormously — some states have none at all, others are progressive with their own brackets, and several cities add local tax on top. Adding a state layer without doing it properly would make the answer look more precise than it is.

Employer benefit deductions, health and dental premiums, HSA or FSA contributions, retirement loan repayments, garnishments, union dues, imputed income on group life cover, and state and local withholding. Payroll stubs carry a lot that a federal estimate cannot see.
