About This Calculator
This calculator shows exactly how the progressive federal tax system applies to your income — breaking down how much of your income falls into each marginal tax bracket, and how much tax is owed at each rate. It's a more detailed, educational companion to the Federal Tax Calculator.
How This Is Calculated
Total Tax = Σ (Income in Each Bracket × That Bracket's Rate)
An $85,000 single-filer income splits across the 10%, 12%, and 22% brackets, for about $10,655 total federal tax.
Assumptions
- Uses 2026 federal tax brackets and the standard deduction (IRS Rev. Proc. 2025-32).
- Does not include tax credits or state/local tax.
