A single filer with $75,000 of taxable income in 2025.
Estimated federal tax: $11,553 — an effective rate of 15.4% and about $63,447 take-home.
The US uses a progressive system: different portions of your income are taxed at different rates (brackets). Only the dollars in each bracket are taxed at that bracket's rate — your whole income is never taxed at the top rate.
Marginal rate is the rate on your last dollar; effective rate is total tax ÷ total income. They are different, and the effective rate is what really matters for budgeting.
Estimate only — excludes state tax, the standard/deduction specifics, credits, and AMT. Always file with a professional or IRS-approved software.
Is this my total tax bill?
No. This estimates only federal income tax. Add state income tax, FICA (Social Security + Medicare), and any local taxes for the full picture.
What's the difference between taxable and gross income?
Gross is your total pay; taxable income is what's left after the standard deduction (or itemized deductions). For 2025 the single standard deduction is $15,000.
Why is my effective rate lower than my marginal rate?
Because only the portion of income in higher brackets is taxed at the higher rate; lower portions are taxed at lower rates.
