What Is a US Paycheck Tax Calculator?
A US paycheck tax calculator estimates how much money you actually take home after all federal, state, and payroll taxes are deducted from your gross salary. Every paycheck in the United States is subject to federal income tax, Social Security tax (FICA), Medicare tax, and — in most states — state income tax. Our free paycheck tax calculator uses the latest 2025 federal tax brackets, standard deductions, FICA rates, and state tax rates for all 50 states to give you an accurate estimate of your net pay per paycheck and annually.
Whether you are evaluating a job offer, planning a budget, or simply trying to understand where your money goes each pay period, knowing your take-home pay is essential. The difference between gross salary and net pay can be substantial — a $75,000 salary in California results in significantly different take-home pay than the same salary in Texas or Florida, where there is no state income tax.

Understanding US Paycheck Taxes
Federal Income Tax
The US uses a progressive federal income tax system with seven brackets ranging from 10% to 37% for 2025. Your income is taxed at increasing rates as it moves through each bracket — not all at your highest rate. The standard deduction ($15,000 for single filers, $30,000 for married filing jointly in 2025) reduces your taxable income before brackets are applied.
Social Security Tax (FICA)
Social Security tax is 6.2% of your gross wages up to the wage base limit of $176,100 for 2025. Your employer pays an additional 6.2%. Income above the wage base is not subject to Social Security tax, which means high earners effectively pay a lower percentage of their total income toward Social Security.
Medicare Tax
Medicare tax is 1.45% of all gross wages with no income cap. An additional 0.9% Medicare surtax applies to wages exceeding $200,000 for single filers or $250,000 for married filing jointly. Unlike Social Security, there is no maximum wage base for Medicare tax.
State Income Tax
State income tax varies widely across the US. Nine states have no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Other states use flat rates (like Illinois at 4.95%) or progressive brackets (like California with rates up to 13.3%). Your state of residence significantly impacts your total tax burden and take-home pay.
2025 Federal Income Tax Brackets
The IRS adjusts federal income tax brackets annually for inflation. For the 2025 tax year, the seven federal tax brackets for single filers are: 10% on income up to $11,925; 12% on $11,926 to $48,475; 22% on $48,476 to $103,350; 24% on $103,351 to $197,300; 32% on $197,301 to $250,525; 35% on $250,526 to $626,350; and 37% on income above $626,350. Married filing jointly brackets are approximately double these thresholds. Our calculator applies these brackets automatically based on your filing status.
States With No Income Tax
If you live in one of the nine states with no income tax — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, or Wyoming — your take-home pay will be noticeably higher than in states with income tax. For example, a $100,000 salary in Texas results in roughly $4,500 to $9,000 more in annual take-home pay compared to the same salary in California or New York, depending on your filing status. Use this calculator to compare take-home pay across different states when evaluating job offers or considering relocation.
How Pre-Tax Deductions Reduce Your Tax Bill
Pre-tax deductions — such as traditional 401(k) contributions, HSA contributions, and employer-sponsored health insurance premiums — reduce your taxable income before federal and state taxes are calculated. For someone in the 22% federal bracket, every $100 contributed to a traditional 401(k) saves approximately $22 in federal taxes plus any applicable state tax savings. This makes pre-tax retirement contributions one of the most effective ways to reduce your current tax burden while building long-term wealth.
