Estimate your 2025 federal income tax, effective rate, and monthly take-home pay using updated tax brackets.

Select your 2025 filing status and use the income slider to enter your gross annual income. Then add any pre-tax deductions — 401(k) contributions, HSA contributions, and other employer-offered pre-tax benefits reduce your adjusted gross income before taxes are calculated.
Choose between the standard deduction (which applies automatically based on your filing status) or enter your itemized deductions if they exceed the standard amount. The calculator applies the 2025 tax brackets to your taxable income and displays your federal tax bill, effective rate, marginal rate, and estimated monthly take-home pay.
Note: This calculator estimates federal income tax only. It does not include FICA taxes (Social Security 6.2% + Medicare 1.45%), state income taxes, or the Net Investment Income Tax.
The United States uses a progressive tax system, meaning different portions of your income are taxed at different rates. Only the income within each bracket is taxed at that rate — not your entire income.
For 2025, the seven brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The breakpoints differ by filing status. Married Filing Jointly brackets are roughly double the Single brackets, which eliminates most of the "marriage penalty" for couples earning similar incomes.
Example: A single filer with $75,000 gross income and the standard deduction ($15,000) has $60,000 in taxable income. They pay 10% on the first $11,925, then 12% on the next $36,550, then 22% on the remaining $11,525 — for a total of approximately $8,818. Their effective rate is about 11.8%, even though they're in the 22% bracket.
Your marginal tax rate is the rate on your next dollar of income — the top bracket you fall into. Your effective tax rate is your total federal tax divided by your total gross income. Because lower income layers are taxed at lower rates, your effective rate is always lower than your marginal rate.
For example, someone in the 24% bracket doesn't pay 24% on all their income. They pay 10% on the first slice, 12% on the next, 22% on the next, and only 24% on income that falls in that bracket. Understanding this distinction is key: when someone says "my taxes went up because I got a raise," only the income that crossed into the next bracket is taxed at the higher rate.
For 2025, the federal tax brackets for single filers are: 10% on income up to $11,925; 12% from $11,926–$48,475; 22% from $48,476–$103,350; 24% from $103,351–$197,300; 32% from $197,301–$250,525; 35% from $250,526–$626,350; and 37% above $626,350. Married filing jointly brackets are approximately double these amounts.
The 2025 standard deductions are: $15,000 for single filers and married filing separately, $30,000 for married filing jointly, and $22,500 for head of household. About 90% of taxpayers use the standard deduction rather than itemizing.
Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you fall into. Your effective tax rate is the average rate across all your income — total tax divided by total taxable income. Because the US uses progressive brackets, your effective rate is always lower than your marginal rate.
Pre-tax deductions like 401(k) contributions and HSA contributions reduce your adjusted gross income before the standard or itemized deduction is applied. This means every dollar contributed to a 401(k) saves you money equal to your marginal tax rate. For someone in the 22% bracket, a $6,000 401(k) contribution saves $1,320 in federal taxes.
