You'll also see your **Effective Tax Rate**, which is the actual percentage of your income that goes to taxes, and your **Marginal Tax Rate**, which is the tax bracket your highest dollar falls into. The **Net Pay** is your estimated annual take-home amount.
Frequently Asked Questions
For the 2025 tax year, there are seven federal income tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Your specific bracket depends on your taxable income and filing status. For example, single filers with taxable income between $11,926 and $48,475 fall into the 12% bracket.
The 2025 Standard Deduction amounts are: $15,750 for Single filers and Married Filing Separately, $31,500 for Married Filing Jointly, and $23,625 for Heads of Household. An additional deduction is available for those aged 65 or older or blind.
Your marginal tax rate is the percentage of tax applied to your *last* dollar earned (the highest bracket you fall into). Your effective tax rate is the average rate you pay on your *total* income after deductions and credits. The effective rate is almost always lower than the marginal rate.
Yes. This calculator estimates your FICA taxes, which include Social Security (6.2% on income up to $176,100) and Medicare (1.45% on all income). It also accounts for the Additional Medicare Tax of 0.9% for high earners.
Contributions to a traditional 401(k) or 403(b) are made pre-tax, meaning they reduce your taxable income for the year. This lowers your current federal income tax bill, potentially keeping you in a lower tax bracket. For 2025, the contribution limit is $23,500 (plus a $7,500 catch-up contribution if you're 50 or older).
Federal tax returns for the 2025 tax year are typically due on April 15, 2026. If the 15th falls on a weekend or holiday, the deadline is moved to the next business day.
Gross Pay is your total earnings before any deductions. Net Pay (or take-home pay) is what lands in your bank account after federal and state income taxes, FICA taxes (Social Security and Medicare), and other deductions like health insurance or retirement contributions are taken out.
This calculator provides an estimate for state taxes based on a flat percentage rate you provide. Because state tax laws vary varying widely (some have progressive brackets, others effectively 0%), we recommend checking your specific state's tax tables for a precise calculation.
For 2025, the Social Security wage base limit is $176,100. This means you only pay the 6.2% Social Security tax on the first $176,100 of your earnings. Income above this amount is not subject to Social Security tax, though Medicare tax still applies.
You should choose whichever method reduces your taxable income the most. Most taxpayers (about 90%) take the Standard Deduction because recent tax law changes significantly increased the standard amounts. However, if your itemizable expenses (like mortgage interest, state and local taxes, and charitable contributions) exceed your standard deduction amount, itemizing may save you money.
