How the 2025 brackets work
Federal ordinary income tax is progressive. Taxable income fills the 10% band first, then the 12% band, and continues upward. Crossing a threshold changes the rate only on the dollars above that threshold.
Taxable income is not the same as salary. Start with income, apply eligible adjustments, then subtract the standard deduction or itemized deductions. Preferential income such as qualified dividends and net long term capital gains follows a separate stacking calculation.
2025 ordinary income thresholds
For single filers, the bracket ceilings are $11,925, $48,475, $103,350, $197,300, $250,525, and $626,350 before the open-ended 37% band. Joint thresholds are $23,850, $96,950, $206,700, $394,600, $501,050, and $751,600.
Head of household and married filing separately use different boundaries. Choosing a status from habit can produce a materially wrong result, so confirm eligibility before using a table.
- Single and married filing separately standard deduction: $15,750.
- Head of household standard deduction: $23,625.
- Married filing jointly and qualifying surviving spouse standard deduction: $31,500.

Marginal rate versus effective rate
The worked example reaches the top of the 22% band, but 22% is not the effective rate on gross wages. Income below the deduction is untaxed, and lower taxable layers use 10% and 12%.
Payroll taxes, credits, capital gains, NIIT, state tax, and deductions can all change the useful effective rate for a real decision.

Frequently asked questions
If I enter the 24% bracket, is all my income taxed at 24%?

Are these the brackets for returns filed in 2026?
Yes. These are tax year 2025 brackets, generally used on 2025 federal returns filed in 2026.
