What is the Tax Bracket Calculator?
Find your marginal bracket and total 2026 federal income tax. To use the Tax Bracket Calculator, enter taxable income, filing status; it returns federal income tax, effective rate, marginal rate, and shows them instantly as you type.
How income is taxed
Federal income tax is progressive, so higher slices of income are taxed at higher rates. Your filing status, deductions and pre-tax contributions determine your taxable income. Start with the income tax calculator and then see the effect on your paycheck with the take-home paycheck calculator.
Pay and filing questions
To compare hourly, weekly and yearly pay, use the salary calculator. If you are married, the marriage tax calculator compares filing together with filing as two single people.
How to use the Tax Bracket Calculator
- Fill in the fields. You will need Taxable income ($). Use the tax year and filing status that apply to you, and gross figures unless a field says otherwise. Fields marked optional can stay at zero.
- Choose your options. Filing status change how the result is worked out, and the form updates to match your choice.
- Read the result. The highlighted box gives the Federal income tax, and the cards below show Effective rate, Marginal rate. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Tax Bracket Calculator using the default values shown in the calculator above:
Inputs
| Taxable income ($) | 92,000 |
|---|---|
| Filing status | Single |
Results
| Federal income tax | $14,952.00 |
|---|---|
| Effective rate | 16.25% |
| Marginal rate | 22% |
With these inputs the calculator returns Federal income tax: $14,952.00. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Taxable income ($) from 92,000 to 110,400 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Federal income tax | $14,952.00 | $19,094.00 | +27.7% |
| Effective rate | 16.25% | 17.3% | +6.4% |
| Marginal rate | 22% | 24% | +9.1% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
What the results tell you
The results panel of the Tax Bracket Calculator reports Federal income tax, effective rate and marginal rate. Compare these figures while changing one input at a time, and use the related calculators below to look at the same situation from another angle.
Method and limits. This calculator applies the formula in the section above to your inputs, in your browser; nothing you enter is stored on our servers. Tax rules change every year and depend on your full situation (state, filing status, credits), so treat the result as an estimate and confirm it with the IRS or a tax professional. It is for information, not financial, tax or legal advice.
