Understanding your tax bracket is the single most useful thing you can do before you file, because it tells you how much of your next raise, bonus, or side-hustle income the federal government will actually take. This tax bracket calculator applies the official 2024 IRS progressive brackets to your gross income, subtracts the standard deduction for your filing status, and shows your marginal rate, your real effective rate, the tax you owe, and your estimated take-home pay.
The key idea most people get wrong: a higher bracket never taxes your whole income. You pay 10% on your first slice of taxable income, 12% on the next slice, and so on. Earning one dollar more that pushes you into the 22% bracket does not raise your tax on every dollar you already earned. Enter your numbers below and the result card updates instantly.
How to Use
- Enter your Annual Gross Income — your total wages, salaries, and self-employment income before anything is withheld. Use your full-year estimate; you can adjust it later to stress-test a raise or bonus.
- Select your Filing Status. Your choice picks the correct bracket table and standard deduction. Single and Married Filing Separately share the narrowest brackets; Married Filing Jointly roughly doubles each bracket's width; Head of Household uses its own, slightly more generous schedule.
- If you contribute to a Traditional 401(k) or Traditional IRA, enter that annual amount in the Pre-Tax Retirement field. Those contributions come out of your pay before tax, so they lower your taxable income dollar for dollar. Leave it at zero if you do not make any pre-tax retirement contributions.
- Read the result card. Estimated Federal Tax is the headline number. Marginal Bracket is the rate on your next dollar of income. Effective Tax Rate is your real average rate — almost always far lower than the marginal bracket.
The engine subtracts your standard deduction first, then walks your taxable income through each 2024 bracket band, adding that band's rate times the dollars inside it. It assumes the standard deduction; if you itemize on Schedule A instead, treat this as a baseline and subtract your actual itemized deductions to refine it.
How the 2024 Tax Brackets Work
The United States uses a progressive, marginal system with seven ordinary-income rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For a Single filer in 2024 the bands run: 10% on taxable income up to $11,600, 12% from there to $47,150, 22% to $100,525, 24% to $191,950, 32% to $243,725, 35% to $609,350, and 37% on every dollar above that.
The standard deduction removes a chunk of income from taxation before any bracket applies. For 2024 it is $14,600 for Single filers, $29,200 for Married Filing Jointly, $14,600 for Married Filing Separately, and $21,900 for Head of Household. So a Single worker earning $85,000 does not pay tax on the first $14,600 — their taxable income is $70,400, and only that amount flows through the brackets.
That is why the marginal rate and the effective rate differ so much. Marginal is the bracket your top dollar lands in; effective is total tax divided by gross income. A $85,000 Single earner sits in the 22% marginal bracket yet pays an effective rate around 12% — because the first dollars were taxed at 10% and 12%.
Examples
Example 1 — A Single professional earning $85,000. With the $14,600 standard deduction, taxable income is $70,400. The first $11,600 is taxed at 10% ($1,160), the next $35,550 at 12% ($4,266), and the remaining $23,250 at 22% ($5,115). Total federal tax is about $10,541, the marginal bracket is 22%, the effective rate is about 12.4%, and estimated take-home pay is roughly $74,459. This shows why a raise to $90,000 is not taxed "mostly at 22%" — only the dollars above $47,150 of taxable income are.
Example 2 — A married couple filing jointly, $120,000 income, $10,000 to a 401(k). Pre-tax retirement drops taxable income before the deduction. After the $29,200 joint standard deduction and the $10,000 deferral, taxable income is $80,800. That sits entirely in the 10% and 12% MFJ bands, producing about $9,232 of federal tax, a marginal bracket of 12%, an effective rate near 7.7%, and take-home pay around $110,768. Contributing to the 401(k) kept them out of the 22% bracket on that income.
Example 3 — A high earner at $1,500,000. Even after the $14,600 Single deduction, taxable income is about $1,485,400. Dollars flow through every band up to the top 37% marginal rate. Total federal tax is roughly $507,786, the effective rate climbs to about 33.9%, and take-home pay is near $992,214. Notice the effective rate still sits well below the 37% marginal bracket — the progressive bands protect the first hundreds of thousands of dollars.
FAQ
What is my marginal tax bracket?
Your marginal tax bracket is the rate you pay on the next additional dollar of taxable income. For 2024 Single filers the brackets are 10% to $11,600, 12% to $47,150, 22% to $100,525, 24% to $191,950, 32% to $243,725, 35% to $609,350, and 37% above that. Enter your income above to see exactly which band your top dollar lands in.
Why is my effective tax rate lower than my bracket?
Because the US system is progressive. The marginal bracket applies only to the dollars inside that band, not to your entire income. The first slice of your income is taxed at 10%, the next at 12%, and so on. The effective rate — total tax divided by gross income — blends all those bands together, so it is always lower than your top marginal bracket.
Do I pay the standard deduction or itemize?
Most taxpayers claim the standard deduction because it is simpler and, for 2024, $14,600 for Single filers and $29,200 for married couples filing jointly. You itemize on Schedule A only if your deductible expenses — mortgage interest, state and local taxes capped at $10,000, charitable gifts, and large medical bills — add up to more than the standard deduction. This calculator uses the standard deduction as its baseline.
Do 401(k) or IRA contributions lower my bracket?
Traditional 401(k) and Traditional IRA contributions reduce your taxable income dollar for dollar, which can push you into a lower bracket or keep more of your income in the lower bands. Enter your annual pre-tax retirement contribution above to see the effect directly. Roth contributions do not lower your current taxable income.
How does my filing status change my bracket?
Filing status selects the bracket table and the standard deduction. Married Filing Jointly roughly doubles the width of every bracket compared to Single and nearly doubles the standard deduction. Head of Household uses a more generous schedule for unmarried people who support a qualifying dependent. Married Filing Separately generally narrows the brackets and is rarely the cheaper choice.
Does a bonus push me into a higher bracket?
A bonus is taxed as ordinary income, but only the portion that crosses a bracket edge is taxed at that higher rate. It may also be withheld at a flat 22% (or 37% for amounts over $1 million), but that is a withholding rate, not your true tax. Your final bracket is recalculated on your full return, and the calculator above shows the real marginal and effective effect of extra income.
