How it works

The US federal system is progressive: each bracket's rate only applies to the income within that bracket, not your whole income. This calculator subtracts the standard deduction first, then applies simplified 2026 bracket thresholds for your filing status.

Illustrative estimate only, using simplified/rounded 2026 figures — not tax advice. Actual federal, state, and payroll tax rules are more detailed. Always confirm with the IRS or a licensed tax professional.
