Frequently asked questions
What's the difference between marginal and effective tax rate?
Your marginal rate is the percentage on your last dollar earned — the highest bracket you reach. Your effective rate is total tax divided by total income, which is always lower because earlier dollars are taxed at lower rates.
Which states have no income tax?
Nine states have no broad-based state income tax on wages: Alaska, Florida, Nevada, New Hampshire (interest and dividends only, fully phased out by 2025), South Dakota, Tennessee, Texas, Washington, and Wyoming.
Are Social Security and Medicare taxes included?
Yes. FICA includes 6.2% Social Security (up to the 2026 wage base of $176,100), 1.45% Medicare on all wages, and the 0.9% Additional Medicare Tax above $200,000 (single) or $250,000 (married filing jointly).
