See exactly how your income flows through each federal tax bracket. Understand the difference between your marginal rate and effective rate at a glance.
The U.S. federal income tax system uses progressive brackets. This means your income is not all taxed at one rate. Instead, each portion of your income is taxed at an increasing rate as you earn more. The first dollars you earn are taxed at the lowest rate (10%), and only the income above each threshold is taxed at the next higher rate.
Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you reach. Your effective tax rate is the total tax you pay divided by your total income, which is always lower than your marginal rate because those first dollars were taxed at lower rates.
The standard deduction reduces your taxable income before brackets apply. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married filing jointly. This means if you earn $95,000 as a single filer, only $78,900 is actually subject to federal income tax.
State income taxes add another layer. Some states use a flat rate (one percentage for all income), while others use graduated brackets similar to the federal system. Nine states charge no income tax at all. Combined with federal taxes and FICA, your total effective rate determines your actual take-home pay.
