The US federal income tax system is progressive. You pay each rate only on income within that bracket, not on your entire income. The brackets below are based on 2025 IRS rates with inflation adjustments. The IRS publishes final 2026 brackets in late 2025; this page will update when they're released.
Marginal vs. Effective Tax Rate
Your marginal rate is the rate you pay on your last dollar of income. Your effective rate is your total tax divided by your total income. They are always different for anyone not in the 10% bracket.
Example: Single filer, $75,000 gross, $60,000 taxable income (after standard deduction):
- 10% on first $11,925 = $1,192.50
- 12% on $11,926 to $48,475 = $4,386.00
- 22% on $48,476 to $60,000 = $2,535.50
- Total federal tax: $8,114.00
- Marginal rate: 22%
- Effective rate: $8,114 ÷ $75,000 = 10.8%
Many people overestimate their taxes because they apply their marginal rate to all income. That's incorrect.
