US Income Tax Calculator (2025)
Federal + FICA + all 50 states. Enter your gross annual pay — no button, results update as you type.
Before taxes. W-2 wages only — this tool does not model 1099/self-employment tax.
US Income Tax Calculator
This calculator estimates your 2025 take-home pay as a W-2 employee anywhere in the United States — federal income tax, Social Security, Medicare, and the income tax (or lack of it) in whichever state you live in. Enter your gross annual income, pick your filing status and state, and the numbers update immediately; there’s nothing to submit and nothing to sign up for. It uses the 2025 tax year — the one most people are earning under right now, filed in spring 2026 — including the higher standard deduction from the One Big Beautiful Bill Act (OBBBA), signed into law in July 2025. If another calculator you’ve used recently quoted a lower take-home number, that law is very likely why.
How US Income Tax Works
Three separate things come out of a paycheck, and this calculator shows all three separately rather than one lump “taxes” number.
Federal income tax is progressive: seven brackets from 10% to 37%. You don’t pay your top bracket’s rate on your whole income — only on the slice that falls inside that bracket. Everything below your standard deduction isn’t taxed at all.
FICA payroll tax is Social Security (6.2%, but only on the first $176,100 you earn in 2025 — nothing above that) and Medicare (1.45%, on every dollar, no cap at all). Above $200,000 (or $250,000 married filing jointly), an extra 0.9% Additional Medicare Tax applies on top — this one has no employer match and isn’t capped once it starts.
State income tax depends entirely on where you live, and varies more than most people expect. Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — charge $0 state income tax on wages. Most of the other 41 tax income progressively, similar in shape to the federal system but with their own brackets and standard deduction; a handful use one flat rate on all taxable income instead of brackets. A few states also withhold their own payroll tax (disability or paid-family-leave insurance) on top of state income tax, similar in spirit to FICA but state-run — California’s SDI and Washington’s WA Cares/Paid Family & Medical Leave are both modeled explicitly in this calculator.
2025 Federal Tax Brackets
Rates apply only to the income inside each bracket, not your whole income — see “Effective vs. Marginal Rate” below for why your actual tax bill is always lower than “your bracket × your income” would suggest.

How We Calculate Your Tax
- Your federal standard deduction ($15,750 single / $31,500 married filing jointly / $23,625 head of household / $15,750 married filing separately, all post-OBBBA 2025 figures) comes off your gross income first.
- What’s left — your federal taxable income — runs through the seven federal brackets above, one slice at a time.
- If your state taxes income, the same two-step process happens again with that state’s own standard deduction and bracket table (or flat rate).
- Social Security, Medicare, and Additional Medicare Tax are calculated separately, straight off your gross income — the standard deduction doesn’t reduce what FICA applies to, a common point of confusion.
- Everything gets added up and subtracted from your gross income to show your net take-home pay, both annually and per month.
What Is Your Take-Home Pay?
“Gross income” is what you’re paid before anything comes out. “Taxable income” is gross income minus your standard deduction — the number tax brackets actually apply to. “Net income” (take-home pay) is what’s left after federal tax, state tax, and FICA are all subtracted — the number that actually lands in your bank account. The gap between gross and net is usually bigger than people expect, mostly because FICA applies to every dollar of gross income with no standard deduction of its own, even though income tax does get that deduction.
Example Calculation
Take a single filer earning $75,000/year with no state income tax (say, Texas or Florida). Their federal taxable income is $75,000 − $15,750 = $59,250. Running that through the 2025 brackets: 10% on the first $11,925, 12% on the next $36,550, and 22% on the remaining $10,775 — $7,949.00 in federal tax. Social Security is $75,000 × 6.2% = $4,650.00; Medicare is $75,000 × 1.45% = $1,087.50. No state tax. Total tax: $13,686.50. Net income: $61,313.50/year, or $5,109.46/month — an effective tax rate of 18.2%, even though this person’s top (marginal) rate is 22%.
What Can Change Your Tax?
Filing status is the biggest lever most people control directly — married filing jointly generally means wider brackets and a bigger standard deduction than filing separately. Which state you live (and are taxed) in matters enormously: the same $75,000 salary owes $0 state tax in Texas and a real, calculable amount in California or New York. Beyond what this calculator models: itemized deductions (mortgage interest, large charitable gifts) can beat the standard deduction for some filers; 401(k)/HSA/traditional-IRA contributions reduce taxable income further; tax credits (Child Tax Credit, education credits) reduce tax owed directly rather than reducing income; and self-employment income is taxed under a completely different system (self-employment tax) that this calculator doesn’t model at all.
Who Should Use This Calculator?
Anyone who wants a fast, realistic answer to “what will actually land in my account” — before accepting a job offer, negotiating a raise, comparing an offer in one state against another, or just understanding a new paycheck. It’s built for W-2 employees specifically; if you’re self-employed or run a 1099 business, this calculator’s FICA math doesn’t apply to you (see the FAQ). It’s not a replacement for tax software or a CPA at filing time — it doesn’t handle itemizing, credits, or anything outside a standard-deduction W-2 scenario.

Frequently Asked Questions
Is this calculator updated for the 2025 tax law changes (OBBBA)?
Yes — see the worked example and methodology sections above; the standard deduction figures used are the post-OBBBA 2025 amounts, not the lower ones the IRS had announced before the law passed.
Does this include itemized deductions, tax credits, or the AMT?
No. Standard-deduction-only, no itemizing, no credits besides California’s small structural exemption credit, no AMT, no Qualified Business Income deduction.
Why is my Social Security tax capped but Medicare isn’t?
Social Security only applies to the first $176,100 you earn in 2025. Medicare applies to every dollar, plus an extra 0.9% above $200,000 (single) or $250,000 (married filing jointly).
Does this work for self-employed or 1099 income?
No — self-employment tax (15.3%, both halves of FICA) is a different calculation this tool doesn’t perform.
Does this calculator cover all 50 states?
Yes. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) have no state income tax on wages. The other 41 are modeled with their own 2025 brackets or flat rate. Some states also layer city/county income tax or a state-run payroll tax on top — see each state’s note in the calculator for specifics not modeled here.
Why does New York show different numbers for Head of Household filers?
New York doesn’t publish a separate bracket table for Head of Household — this calculator approximates it using New York’s Single rates with New York’s own Head of Household standard deduction. Flagged directly in the tool when you select that combination.
This calculator provides an estimate based on the tax rules and assumptions stated above. Your actual tax liability may differ depending on your personal circumstances, deductions, credits, residency, income sources and other factors.
