How Federal Income Tax Works
The US federal income tax uses a progressive bracket system. This means you don't pay one flat rate on all your income. Instead, different portions of your income are taxed at different rates.
For example, if you're single with $85,000 of taxable income in 2026, you don't pay 22% on the entire amount. You pay 10% on the first $11,925, 12% on income from $11,925 to $48,475, and 22% on income above $48,475.
- Marginal Rate: The tax rate on your last dollar of income (your highest bracket)
- Effective Rate: Your total tax divided by total income (what you actually pay overall)
- Standard Deduction: An amount subtracted from your income before tax is calculated ($15,000 for single filers in 2026, estimated)
