Income Tax Calculator – How Much Does Tax Actually Take?

Your salary and your take-home pay are two very different numbers — and understanding the gap is one of the most important financial calculations you can make. Between federal income tax, Social Security, Medicare, and state taxes, a $100,000 salary in a high-tax state might net you $68,000–$72,000. In a no-income-tax state, that same salary might yield $76,000–$79,000. This calculator shows exactly where your money goes. Enter your gross income, filing status, and state to see your federal income tax broken down by bracket, your FICA contributions (Social Security at 6.2% and Medicare at 1.45%), your effective rate, and your true monthly and annual take-home pay. Many people mistakenly believe they're "in the 22% bracket" and fear earning more will hurt them. In reality, marginal tax rates only apply to income above each threshold — not your entire salary. On a $55,000 single-filer income, only the income between $47,150 and $55,000 is taxed at 22%. The rest is taxed at 10% and 12%. Understanding this distinction changes how you think about raises, bonuses, 401(k) contributions, and side income.

Federal income tax uses progressive brackets (2024, single): · 10% on first $11,600 · 12% on $11,601–$47,150 · 22% on $47,151–$100,525 · 24% on $100,526–$191,950 · 32% on $191,951–$243,725 · 35% on $243,726–$609,350 · 37% on income above $609,350 Tax = sum of each bracket's rate × income within that bracket, applied to (Gross income – Standard deduction). FICA = (6.2% Social Security on income up to $168,600) + (1.45% Medicare on all income). Effective rate = Total federal tax ÷ Gross income (always lower than your marginal bracket).
