Estimate your federal tax bill for any recent tax year from your income, filing status and deductions.
How this calculator arrives at its answer
A tax calculator turns the bracket tables into a single number. Select the tax year you are filing for — brackets and the standard deduction are indexed each year, so the same income produces a different bill in different years.
Pre-tax contributions such as a traditional 401(k) or HSA reduce taxable income directly, so adding them here shows the tax saving immediately.
Try it with these numbers
The calculator opens with a gross annual income of 75,000. On those figures the federal tax owed is $8,114. Underneath, Taxable income comes out at $60,000 and Deduction used at $15,000. Change any field and every figure updates as you type.
Step by step
- Enter your gross income for the year.
- Select filing status, tax year and deduction type.
- Add pre-tax contributions to see the reduction in tax.
The formula
taxable income = gross − pre-tax − deduction
tax = sum of each bracket slice at its own rate

Which tax year should I pick?

Are the 2026 figures final?
No — 2026 brackets shown here are projected from inflation indexing and will be replaced when the IRS publishes final numbers.
