What's Your Salary Actually Worth After Tax?

Four things reduce a salaried paycheck before you see it: federal income tax (progressive brackets on your taxable income), Social Security (6.2% up to a wage cap of $176,100 in 2025), Medicare (1.45%, plus 0.9% on high earnings), and state and local income tax where it applies.

Pre-tax contributions change the maths. A traditional 401(k) lowers your federal and state taxable income but not your Social Security and Medicare wages. Pre-tax health premiums and HSA contributions lower all of them.

Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — don't tax wage income at all. Others range from a flat ~2.5% (Arizona) to progressive brackets topping 10%+ (California, New York, New Jersey, Hawaii), before any city tax. On a $150,000 salary that's a difference of well over $10,000 a year in take-home.

Your marginal rate is what the next dollar is taxed at — useful for deciding whether a raise or a 401(k) bump is worth it. Your effective rate is total tax divided by gross pay, and it's always lower because the early brackets are taxed less. Both are shown above.
