Introduction
This free Taxable Income Calculator helps you estimate your federal income tax in just a few steps. Enter your income, deductions, and credits, and the tool does the math for you. It shows your taxable income, total tax owed, effective tax rate, and marginal tax bracket. You can also see a step-by-step breakdown of how your tax is calculated.
The calculator supports tax years 2023, 2024, and 2025. It covers all five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Surviving Spouse. It handles W-2 wages, self-employment income, capital gains, dividends, interest, rental income, Social Security benefits, and more.
Built-in features include automatic self-employment tax calculations, the standard deduction vs. itemized deduction comparison, the Child Tax Credit, Earned Income Tax Credit (EITC), education credits, and a withholding estimator. A what-if tool lets you see how adding extra pre-tax retirement contributions could lower your tax bill. This calculator gives a federal tax estimate only — state taxes are separate and vary by state.

What Is Taxable Income?
Taxable income is the part of the money you earn that the federal government charges tax on. It is not the same as your total income. You start with all the money you made in a year, then subtract certain amounts the IRS lets you remove. What is left over is your taxable income.
How Taxable Income Is Calculated
First, you add up all your income sources. This includes wages from a job, money from a business, interest from a bank account, dividends from stocks, and capital gains from selling assets. The total is called your gross income. You can estimate your total yearly earnings with our Annual Income Calculator.
Next, you subtract above-the-line adjustments. These are things like student loan interest, HSA contributions, and traditional IRA contributions. The result is your adjusted gross income (AGI). AGI is an important number because many tax rules and credits depend on it. Our MAGI Calculator can help you determine your modified AGI, which is used for additional phaseout calculations.
After that, you subtract either the standard deduction or your itemized deductions, whichever one is bigger. The standard deduction is a flat amount set by the IRS each year. Itemized deductions include things like mortgage interest, state and local taxes (up to $10,000), and charitable donations. You also subtract any qualified business income (QBI) deduction if you have pass-through business income.
The number you are left with is your federal taxable income. This is the amount used to figure out how much income tax you owe. For a quick look at how your income falls into each bracket, try our Tax Bracket Calculator.
How Federal Income Tax Brackets Work
The U.S. uses a progressive tax system. This means your income is split into chunks, and each chunk is taxed at a different rate. The rates go from 10% on the lowest chunk up to 37% on the highest. Only the money inside each bracket is taxed at that bracket's rate. Your marginal tax rate is the rate on your last dollar of income. Your effective tax rate is the average rate you actually pay across all your income. The effective rate is always lower than the marginal rate. You can explore this in more detail with our Effective Tax Rate Calculator.
Long-Term Capital Gains and Qualified Dividends
Money you make from selling investments held longer than one year and qualified dividends get special, lower tax rates. These rates are 0%, 15%, or 20% depending on your income level. This is different from ordinary income like wages, which is taxed at the regular bracket rates. Use our Capital Gains Tax Calculator to estimate the tax on your investment gains, or check the Dividend Yield Calculator to evaluate your dividend-paying investments. If you want to track your overall investment profit, the Stock Profit Calculator is a helpful tool.
Tax Credits vs. Tax Deductions
A deduction lowers the amount of income that gets taxed. A tax credit directly lowers the tax you owe, dollar for dollar. Credits are more valuable. Common federal tax credits include the Child Tax Credit, the Earned Income Tax Credit (EITC), education credits like the American Opportunity Credit, and the Child and Dependent Care Credit. Some credits are refundable, meaning they can give you money back even if you owe zero tax. To see if you're on track for a refund, try our Tax Refund Calculator.
Other Federal Taxes to Know About
Self-employment tax covers Social Security and Medicare for people who work for themselves. You can estimate this separately with our Self-Employment Tax Calculator. The Net Investment Income Tax (NIIT) is an extra 3.8% tax on investment income for higher earners. The Alternative Minimum Tax (AMT) is a separate calculation that makes sure high-income taxpayers pay at least a minimum amount. These taxes are added on top of your regular income tax.
This calculator estimates your federal taxes only. State income taxes are separate and vary depending on where you live.
