Tax brackets, marginal rate and effective rate
Federal tax brackets are progressive. Income is split across brackets, so reaching a higher bracket does not mean all income is taxed at that rate.
Worked example
A single filer with $90,000 gross income first subtracts the 2026 standard deduction. The remaining taxable income is taxed in layers across the 10%, 12% and higher brackets reached.
Methodology
The calculator subtracts the standard deduction and extra deductions entered, applies each 2026 federal bracket, then reports marginal and effective rates.
