Formula
The calculator starts from your gross income and subtracts any above-the-line adjustments to reach your adjusted gross income (AGI). From AGI it takes the larger of your standard deduction or your itemized deductions — for 2025 the single standard deduction is $15,750 — to leave your taxable income (AGI − deduction, never below zero). That taxable income is run through the seven progressive brackets (10, 12, 22, 24, 32, 35, 37%) for your filing status and year. The rates are marginal: each one applies only to the income that falls inside its band, so your effective rate always lands below your top marginal rate. Adding the per-band amounts gives your gross federal tax, from which any non-refundable credits are subtracted dollar-for-dollar. Separately it figures employee FICA — Social Security at 6.2% up to the wage base plus Medicare at 1.45%, with an extra 0.9% on high wages — and optionally NIIT, a simplified AMT (you pay whichever is higher), and a state estimate. Everything is summed into total tax and take-home pay. Treat every result as an estimate.
Example
Take a single filer in 2025 earning $80,000 in wages who claims the standard deduction and owes no state tax. The $15,750 standard deduction comes off first, leaving taxable income of $80,000 − $15,750 = $64,250. That amount is sliced across the brackets: the first $11,925 is taxed at 10% (= $1,192.50), the next $36,550 at 12% (= $4,386.00), and the remaining $15,775 at 22% (= $3,470.50). Add those bands and your federal income tax is $9,049. Your marginal rate is 22% — the rate on your last dollar — but your federal effective rate is just $9,049 ÷ $80,000, about 11.3%, because most of your income was taxed in the lower bands. Next comes employee FICA: Social Security at 6.2% is $4,960 and Medicare at 1.45% is $1,160, totaling $6,120 (no Additional Medicare applies below $200,000). Combine the two and your total tax is $9,049 + $6,120 = $15,169, roughly 19.0% of gross pay. That leaves take-home pay of $64,831 a year, about $5,403 a month. These figures are estimates — verify with the IRS or a tax professional before you file.
Definitions
- Gross income
- Your total income before any deductions: wages, salaries, tips, interest, dividends and other taxable income. On this calculator it is the starting figure, before above-the-line adjustments reduce it to your adjusted gross income.
- Adjusted gross income (AGI)
- Your gross income minus above-the-line adjustments such as certain retirement or student-loan items. AGI drives many phase-outs and thresholds, and on this calculator it is the figure your deduction is subtracted from to reach taxable income.
- Taxable income
- AGI minus your standard or itemized deduction. This is the figure the seven progressive brackets actually apply to; for a single filer in 2025 with $80,000 of wages and the standard deduction, it works out to $64,250.
- Standard deduction
- A flat amount that reduces taxable income with no receipts needed. For 2025 it is $15,750 single, $31,500 married filing jointly, $23,625 head of household and $15,750 married filing separately; most filers simply take it.
- Itemized deductions
- Specific write-offs such as mortgage interest, state and local taxes, charitable gifts and large medical costs, claimed instead of the standard deduction. You itemize only when their total exceeds your standard deduction; otherwise the standard amount wins.
- Marginal tax rate
- The rate on your next dollar of income, equal to your top bracket: 10, 12, 22, 24, 32, 35 or 37%. Because brackets are progressive, only the income within each band is taxed at that band's rate.
- Effective tax rate
- Your total tax divided by income, shown as a percentage. It is always lower than your marginal rate because earlier dollars are taxed in lower brackets; the $80,000 single example lands near an 11.3% federal effective rate.
- FICA / payroll tax
- The employee Social Security and Medicare withheld from wages: 6.2% up to the annual Social Security wage base plus 1.45% on all wages, with an extra 0.9% Medicare on high earnings. It is separate from income tax.
- Net Investment Income Tax (NIIT)
- An extra 3.8% levied on the lesser of your net investment income and the amount your modified AGI exceeds the threshold: $200,000 single, $250,000 married filing jointly, or $125,000 married filing separately.
- Alternative Minimum Tax (AMT)
- A parallel calculation with 26% and 28% rates and an income-phased exemption, designed so high earners with many deductions still pay a minimum. You owe it only if it exceeds your regular tax; few do after the TCJA.
- Withholding
- The income tax your employer subtracts from each paycheck and sends to the IRS on your behalf, set by your Form W-4. Withholding too little leaves a balance due at filing; withholding too much produces a refund.
- Refund vs amount owed
- The difference between the tax you already paid through withholding and estimates and your actual tax for the year. Overpaying yields a refund; underpaying means a balance due, sometimes with penalties. These figures are estimates only.
Good to know
How US income tax actually works
The number on your paycheck and the number the IRS taxes are rarely the same, and the gap between them is where this calculator does its work. Everything starts with your gross income — wages, salary, and other earnings before anything is taken out. From there you subtract above-the-line adjustments (things like deductible retirement contributions or student-loan interest) to arrive at your adjusted gross income, or AGI. AGI is the pivot point of the whole return: many other limits key off it. Next you subtract a deduction. Most people take the standard deduction — a flat amount set by your filing status that rises a little each year (for 2025 it is $15,750 if you are single, $31,500 if married filing jointly). If your deductible expenses — mortgage interest, state taxes, charitable gifts — add up to more, you itemize instead and take the larger figure. Whatever you subtract, what remains is your taxable income, and that, not your salary, is the figure the brackets actually touch. Now the progressive part. The US uses seven brackets — 10, 12, 22, 24, 32, 35 and 37% — but each rate applies only to the income that falls inside its band, not to your whole income. This is why your marginal rate (the rate on your last dollar) is always higher than your effective rate (the tax you actually pay divided by your income). A single filer with $80,000 of wages in 2025, taking the standard deduction, has $64,250 of taxable income and owes $9,049 — built from 10% of the first $11,925, 12% of the next $36,550, and 22% only on the slice above $48,475. Their marginal rate is 22%, but their effective federal rate is about 11.3%. After the brackets produce a tentative tax, credits come off dollar-for-dollar — a $1,000 credit cuts your bill by a full $1,000, unlike a deduction. What is left is what you owe in federal income tax. Two more things matter. The system is pay-as-you-go: tax is withheld from each paycheck, so filing usually just reconciles what you have already paid rather than springing a surprise. And income tax is only part of the story — Social Security and Medicare payroll taxes come out separately. That same $80,000 earner pays $6,120 in employee FICA on top of income tax, which is why this tool shows your total tax and true take-home, not just the bracket math. Every figure here is an estimate built from current-year rules — confirm it against the IRS or a tax professional before you file.
Tax brackets explained: why your top rate is not your real rate
Here is the single most common tax misconception: that earning one dollar more and crossing into a higher bracket suddenly taxes every dollar you make at that higher rate. It does not. The US federal system is marginal, which means each tax rate applies only to the slice of income that falls inside its band — never to the whole amount. A raise can never leave you with less after-tax money simply because it nudged you into the next bracket. Walk through a real example. Suppose you are single in 2025, earn $80,000 in wages, and take the standard deduction of $15,750. That leaves $64,250 of taxable income, which is then sliced across the brackets in order. The first $11,925 is taxed at 10%, which is $1,192.50. The next slice, $36,550, is taxed at 12%, adding $4,386.00. Only the remaining $15,775 — the part that actually sits in the 22% band — is taxed at 22%, which comes to $3,470.50. Add the three pieces together and your federal income tax is $9,049. Notice that the bulk of your income was taxed at 10% and 12%; just the top sliver ever felt the 22% rate. This is where the two rates that describe your situation come apart. Your marginal rate is the rate on your next dollar of income — the band your last dollar lands in. Here that is 22%, so a $1,000 raise would cost you $220 in federal income tax, not a re-taxing of everything beneath it. Your effective rate is the total tax divided by your income: $9,049 on $80,000 of gross wages works out to roughly 11.3%. That single number is what you really pay, on average, across every dollar. Your effective rate is always lower than your marginal rate, and the reason is built into the structure. Because the lower bands are always filled first and taxed at their gentler rates, your average is dragged down by all the income taxed at 10% and 12% before any of it reaches 22%. Only if every dollar you earned sat in the very first bracket could the two rates meet. So when you plan ahead, weigh decisions against your marginal rate, but judge your true burden — and compare year to year — by your effective rate. Both figures here are estimates; confirm the specifics with a tax professional or the IRS before you file.
Standard vs itemized deductions
When you file, you reduce your taxable income with either the standard deduction or your itemized deductions — whichever is larger. You cannot use both, so the decision comes down to simple arithmetic: take the bigger number and pay tax on less income. The standard deduction is a flat, no-questions-asked amount set by Congress and adjusted each year. For 2025, reflecting the One Big Beautiful Bill Act, it is $15,750 if you are single or married filing separately, $31,500 if you are married filing jointly, and $23,625 if you file as head of household. Because it requires no receipts and no record-keeping, the standard deduction is the simplest choice and the right answer for the large majority of taxpayers. Itemizing means adding up specific deductible expenses and reporting them individually instead. The four that matter most are state and local taxes, mortgage interest, charitable gifts, and large medical bills. State and local income, sales, and property taxes (together called SALT) are deductible only up to a federal cap, so homeowners in high-tax states often hit the ceiling. Interest on a mortgage for your main or second home is deductible within the limits on loan size. Cash and property donations to qualified charities count, subject to limits tied to your income. Unreimbursed medical and dental expenses are deductible only to the extent they exceed 7.5% of your adjusted gross income, so this category usually helps only in a year of unusually heavy costs. Choosing is straightforward: total your itemized expenses for the year and compare that figure with the standard deduction for your filing status. If your itemized total is larger — common when you own a home with a sizable mortgage, live where SALT is high, or gave generously — you itemize. If it falls short, you take the standard deduction and keep your filing simple. Owning a home, a major medical event, or significant charitable giving are the usual triggers that tip the scales toward itemizing. You do not have to run this comparison by hand. This calculator figures both paths for you and automatically applies the one that lowers your taxable income the most, so your estimate already reflects the better outcome. As with everything here, treat the result as an estimate, and confirm the specifics with a tax professional or the IRS before you file.
Payroll taxes: Social Security, Medicare and the Additional Medicare Tax
The payroll taxes that come out of your paycheck are separate from federal income tax, and they fund Social Security and Medicare under a system known as FICA. Your employer withholds them automatically alongside income tax, so they quietly reduce your take-home pay every pay period even though they never appear on your Form 1040 as income tax. Because they are figured on your wages rather than on your taxable income, the standard deduction and your tax bracket have no effect on them at all. The first piece is Social Security, withheld at 6.2 percent of your wages up to an annual wage base that rises most years: $168,600 in 2024, $176,100 in 2025, and $184,500 in 2026. Once your year-to-date wages cross that ceiling, Social Security withholding stops for the rest of the year, which is why higher earners sometimes see their take-home pay tick up late in the year. The second piece is Medicare, withheld at 1.45 percent of your wages with no cap at all — every dollar you earn is subject to it. On wages of $80,000 in 2025, for example, that combination works out to $4,960 of Social Security plus $1,160 of Medicare, or $6,120 of employee FICA in total. Higher earners face an extra layer called the Additional Medicare Tax: an added 0.9 percent on wages above $200,000 if you are single or head of household, $250,000 if you are married filing jointly, and $125,000 if you are married filing separately. It applies only to the wages above your threshold. Your employer begins withholding it once your pay with that employer passes $200,000, regardless of your filing status, so the exact amount is reconciled when you file. It is worth remembering that what you see here is only the employee side. Your employer pays a matching 6.2 percent for Social Security and 1.45 percent for Medicare out of its own pocket, doubling the amount actually sent to the government, though the employer does not match the 0.9 percent Additional Medicare Tax. This calculator shows only the portion withheld from you, not the employer's share. Treat these figures as estimates of what leaves your paycheck, and check your pay stub or a tax professional for your exact withholding before you rely on them.
The extra taxes higher earners face: NIIT and AMT
Most taxpayers never encounter the two surcharges described here, but if your income climbs into the six figures it pays to understand them — and this calculator estimates both for you. The first is the Net Investment Income Tax (NIIT), a flat 3.8% levy that helps fund Medicare. It applies to the lesser of two amounts: your net investment income — interest, dividends, capital gains, rental and royalty income, and similar largely passive earnings — and the amount by which your modified adjusted gross income (MAGI) exceeds a fixed threshold. Those thresholds are $200,000 if you are single or head of household, $250,000 for married filing jointly, and $125,000 for married filing separately. Because the tax targets the smaller of the two figures, someone who barely crosses the line pays 3.8% on only the few dollars above it, while a high earner with a large portfolio feels the full bite. The thresholds are not indexed for inflation, so over time more households quietly drift into NIIT territory. The second is the Alternative Minimum Tax (AMT), a parallel system built decades ago to stop high earners from erasing their bill through stacked deductions and preferences. You effectively compute your tax a second way: start from a broader income base, subtract a generous AMT exemption, and apply a 26% rate, rising to 28% above a high breakpoint. The exemption itself phases out as income climbs, which is what pulls more income into the AMT net near the top. You owe the AMT only when this parallel figure exceeds your regular tax — in practice you pay whichever is higher. Since the 2017 Tax Cuts and Jobs Act raised the exemption and its phaseout points sharply, very few people now trip the AMT, though large amounts of certain deductions or the exercise of incentive stock options can still trigger it. This tool gives you a simplified estimate of each, so you can see at a glance whether either might reach you. Both taxes rest on definitions and adjustments more intricate than any quick calculation can fully capture, so treat these results as a flag to investigate rather than a final number. If your investment income is substantial or your situation is unusual, confirm the figures with a qualified tax professional or the IRS before you file.
Filing status: the choice that reshapes your brackets
Your filing status is more than a checkbox; it quietly sets the width of every tax bracket you pass through, the size of your standard deduction, and the income thresholds where extra taxes begin. Choose the wrong one and you can overpay by hundreds or thousands, so it is worth understanding how the four options differ. Single applies if you are unmarried and do not qualify for a more favorable status. For 2025 it carries a $15,750 standard deduction and the narrowest brackets, which means you reach each higher rate sooner than other filers do. Married filing jointly (MFJ) combines both spouses' income on one return and roughly doubles those figures: a $31,500 standard deduction and bracket widths that are generally twice the single amounts at the lower rates. This is where the "marriage bonus" appears — when one spouse earns far more than the other, merging incomes pulls the higher earner's dollars into wider, lower-rate bands. When two similar high earners marry, the opposite "marriage penalty" can surface at the top, because the upper brackets do not fully double; the 37% rate starts above $626,350 for a single filer but only $751,600 for a couple. Married filing separately (MFS) splits the couple onto two returns. Its standard deduction matches single — $15,750 in 2025 — but its brackets are exactly half of the joint brackets, so the higher rates bite at far lower income than they would for a single filer, and several credits and deductions shrink or disappear, so it usually costs more overall. Even so, MFS can help in specific cases: when one spouse has large medical bills measured against a smaller income, when you want refunds and liabilities kept separate, or when an income-driven student-loan payment is figured on one spouse's income alone. Head of household (HoH) rewards unmarried people who support a home for a qualifying child or relative. You generally must be unmarried (or considered unmarried), pay more than half the cost of keeping up your home, and have a qualifying person live with you for more than half the year. In return you receive a larger $23,625 standard deduction and wider brackets than single — a meaningful break for many single parents. Because these differences compound through deductions, brackets, and thresholds, the smartest move is to run your own numbers. Switch the filing-status selector and compare the estimated federal tax, effective rate, and take-home for each option you might qualify for. Remember these are estimates; confirm your eligibility and final choice with a tax professional or the IRS before you file.
Credits and adjustments that cut your bill
Two very different levers can lower what you owe, and confusing them is one of the most common tax mistakes. A deduction reduces your taxable income — the figure your brackets are applied to — so its value depends on your marginal rate. If you sit in the 22% bracket, a $1,000 deduction trims your federal tax by roughly $220, not the full $1,000. A credit, by contrast, reduces your tax dollar-for-dollar after the brackets have done their work: a $1,000 credit cuts your bill by the full $1,000 no matter which bracket you top out in. That is why a modest credit often beats a much larger deduction. The deductions easiest to claim are above-the-line adjustments, which come out of gross income to arrive at your AGI before you ever choose between the standard and itemized deduction — so you benefit whether or not you itemize. Contributing to a Health Savings Account, making a deductible traditional IRA contribution, and paying student-loan interest (up to the annual limit) all work this way, lowering your AGI and, with it, your taxable income. Because they shrink AGI, these adjustments can also pull you under the thresholds for other phase-outs. Credits target the tax itself. The Child Tax Credit rewards families with qualifying children; the American Opportunity and Lifetime Learning credits offset tuition and related education costs; the Earned Income Tax Credit (EITC) supports lower- and moderate-income workers; and the Saver's Credit returns a percentage of retirement contributions for eligible filers. Each carries its own income limits and eligibility rules, so confirm the current-year details before counting on one. One important modeling note: this calculator treats every credit as non-refundable. A non-refundable credit can reduce your federal income tax to zero but cannot push it below zero into a refund. In reality, the EITC is fully refundable and part of the Child Tax Credit can be refunded even when it exceeds your tax. For lower-income filers, that means the estimate here may understate the benefit you actually receive — treat the figure as conservative and verify the refundable portions with the IRS or a tax professional before filing. Remember too that these levers stack: trimming AGI with adjustments lowers the income your brackets touch, and credits then reduce whatever tax remains.
Tax-planning strategies and common mistakes
Smart tax planning starts with lowering the income the IRS can tax. Because your tax is figured on taxable income, every dollar you move into a pre-tax 401(k), traditional IRA, or Health Savings Account (HSA) reduces your AGI — and at a 22% marginal rate, a $5,000 contribution can trim roughly $1,100 from your federal bill before it ever touches your investments. If your itemized deductions hover near the standard deduction, consider "bunching" — concentrating charitable gifts or elective medical costs into a single year so you clear the threshold one year and take the standard deduction the next. Investors can harvest capital losses to offset gains, and anyone with a fluctuating income should watch the surtax thresholds: wages above $200,000 (single) trigger the 0.9% Additional Medicare Tax, and MAGI above the same line can expose investment income to the 3.8% Net Investment Income Tax. Knowing the Social Security wage base ($176,100 in 2025) helps too, since earnings above it escape the 6.2% Social Security portion. Just as valuable is managing your withholding. A giant refund is not a windfall — it is an interest-free loan to the government — while under-withholding can leave you with a penalty. Aim to land near zero by adjusting your Form W-4. The most common mistakes are conceptual. Many people confuse their marginal rate with their effective rate: being "in the 22% bracket" never means 22% of everything, because each rate applies only to the income inside its band, so your effective rate is always lower. Others forget FICA entirely — the 6.2% Social Security and 1.45% Medicare taxes hit your first dollar of wages even when income tax is modest. People over-withhold and celebrate the refund, ignore state and local tax that can add several points, and assume every type of income is taxed alike. In reality, long-term capital gains and qualified dividends enjoy preferential 0/15/20% rates; this tool, for simplicity, taxes investment income at your ordinary rate, so use a dedicated capital gains calculator for those. Use this calculator to pressure-test decisions before you act. Change the year, filing status, or deduction method; add a retirement contribution to watch your taxable income and tax fall; or raise wages to see exactly where the surtaxes bite. Treat the results as estimates, then confirm the numbers with a tax professional or the IRS before you file.
Frequently asked questions
How does this calculator estimate my income tax?
It starts with your gross income and subtracts any above-the-line adjustments to find your adjusted gross income (AGI). From AGI it subtracts your standard or itemized deduction to reach taxable income, then applies the seven progressive federal brackets (10% to 37%) for your filing status and tax year. Non-refundable credits then reduce the resulting tax dollar-for-dollar. It also estimates employee FICA, and optionally state tax, NIIT and AMT. Every figure is an estimate, so verify it before you file.
What is the difference between my marginal and effective tax rate?
Your marginal rate is the bracket your last dollar of income falls into; your effective rate is your total federal income tax divided by your income. Because the brackets are progressive, each rate applies only to the income inside its band, so your effective rate is always lower than your marginal rate. For example, a single filer with $80,000 of wages in 2025 lands in the 22% bracket but pays about $9,049, roughly an 11.3% effective federal rate.
Should I take the standard deduction or itemize?
Take whichever is larger. The standard deduction is a flat amount set by your filing status and year. For 2025 it is $15,750 single, $31,500 married filing jointly, $23,625 head of household and $15,750 married filing separately. Itemizing instead adds up specific costs such as mortgage interest, state and local taxes (capped) and charitable gifts. Most filers come out ahead with the standard deduction, so the calculator applies it unless the itemized total you enter is higher.
What is FICA and why is it shown separately from income tax?
FICA is the payroll tax for Social Security and Medicare, withheld from your paycheck separately from federal income tax. The employee share is 6.2% for Social Security on wages up to the annual wage base ($176,100 in 2025), plus 1.45% Medicare on all wages, with an extra 0.9% Additional Medicare on wages above $200,000 single or $250,000 jointly. It funds those specific programs rather than general revenue, so it sits outside your income-tax brackets and appears as its own line. This models the employee side only, not self-employment tax.
Who owes the Net Investment Income Tax (NIIT)?
The NIIT is a 3.8% surtax on investment income for higher earners. It applies to the lesser of your net investment income and the amount your modified AGI exceeds $200,000 single, $250,000 married filing jointly, or $125,000 married filing separately. If your income is below those thresholds, you owe nothing. Investment income includes interest, dividends, capital gains and rental income. The calculator estimates the NIIT automatically and adds it on top of your regular federal income tax.
Will I owe the Alternative Minimum Tax (AMT)?
The AMT is a parallel calculation with a 26% or 28% rate and a special exemption that phases out at high incomes. You compare it with your regular tax and owe the AMT only if it is higher. Since the 2017 tax law raised the exemption, very few people owe it today. This calculator gives a simplified AMT estimate rather than the full Form 6251 computation, so treat any AMT figure as a rough flag to investigate with a tax professional.
How does the calculator estimate my state income tax?
State income tax here is an estimate. The calculator applies your chosen state's 2025 rate or brackets to your federal taxable income and, if you enter one, a flat local rate. It deliberately ignores state-specific deductions, exemptions, credits and add-backs, which vary widely, so the result is a ballpark rather than a filing figure. States with no income tax return zero. Use it to gauge your overall burden, then check your state's department of revenue or a preparer for an exact number.
Why isn't my investment income taxed at capital-gains rates here?
To keep things simple, this calculator taxes all investment income, including long-term capital gains and qualified dividends, at your ordinary bracket rate. In reality, long-term gains and qualified dividends usually receive preferential 0%, 15% or 20% rates, which can be far lower. That means the calculator may overstate the tax on those amounts. If most of your income is long-term gains or qualified dividends, use a dedicated capital gains calculator for a more accurate figure.
How is my refund or balance due figured?
Your refund or balance due is simply the difference between what you have already paid and what you owe. The calculator totals your estimated federal income tax, plus any NIIT or AMT, then compares it with the withholding or estimated payments you enter. If your payments exceed the tax, you see a refund; if they fall short, you owe the difference. Because withholding and credits vary by person, treat the result as a planning estimate, not the exact number on your return.
Which filing status should I choose?
Your filing status sets your standard deduction, bracket thresholds and several phase-outs, so it strongly affects your tax. The calculator offers single, married filing jointly, married filing separately and head of household. Most married couples pay less filing jointly, while head of household, for an unmarried person supporting a dependent, gives wider brackets and a larger deduction than single. Married filing separately is occasionally better in specific situations. Try each status you qualify for and compare the totals.
Is this estimate accurate enough to file my tax return with?
No. Treat every result as an estimate for planning, not a substitute for your return. The engine uses verified brackets, deductions and limits, but it simplifies several areas: investment income is taxed at ordinary rates, state tax ignores local rules, the AMT is approximate, and credits are treated as non-refundable. Your actual return may include credits, deductions or income types it does not model. Use it to plan and budget, then confirm with tax software, the IRS or a professional before filing.
Which tax years does the calculator cover?
The calculator covers tax years 2024, 2025 and 2026, selectable at the top. The 2025 and 2026 figures reflect the One Big Beautiful Bill Act of 2025, including its higher standard deductions, for example $15,750 single and $31,500 married filing jointly in 2025, rising to $16,100 and $32,200 in 2026. Bracket thresholds, the Social Security wage base and other limits are updated for each year, so pick the year that matches the return you are estimating.
