Understanding Income Tax

Income tax in the US is calculated using progressive tax brackets. This means different portions of your income are taxed at different rates — you don't pay the highest rate on your entire income.

Your marginal tax rate is the rate on your last dollar of income. Your effective tax rate is the average rate across all your income — it's always lower than your marginal rate.

Frequently Asked Questions

What are the federal tax brackets for 2026?

The federal income tax for 2026 uses seven progressive tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The specific income range for each bracket is adjusted annually for inflation by the IRS and depends on your tax filing status.

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the tax rate applied to the last dollar you earn (the highest tax bracket you reach). Your effective tax rate is your total income tax liability divided by your total gross income, representing the average tax percentage you actually paid.

How much federal tax do I owe on $100,000?

For a single filer in 2026, earning $100,000 gross income results in a taxable income of $83,900 after subtracting the $16,100 standard deduction. The progressive federal tax on this taxable income is approximately $13,446, representing an effective federal tax rate of 13.4%.

What is the standard deduction for 2026?
