How This Is Calculated
This calculator applies the U.S. federal progressive income tax system per IRC §1. Each tax bracket's rate applies only to income within that bracket, not to your entire income.
Step-by-step calculation
- Start with gross income — your total annual earnings from all sources.
- Subtract above-the-line deductions (HSA contributions, IRA deductions, student loan interest, etc.) to get your Adjusted Gross Income (AGI).
- Subtract the standard deduction (or itemized deductions if higher) to get your taxable income.
- Apply progressive brackets — the first dollars are taxed at 10%, the next portion at 12%, and so on up to 37%.

Frequently Asked Questions
- How much federal income tax do I owe on $75,000?
- A single filer earning $75,000 in 2026 would owe approximately $7,670.00 in federal income tax, for an effective tax rate of 10.2%. This is after the standard deduction of $16,100.00, resulting in $58,900.00 of taxable income. The marginal tax rate is 22%. Note: this does not include state income tax, Social Security, or Medicare taxes.
- What are the 2026 federal tax brackets?
- For 2026, the seven federal income tax rates are: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single filers, the 10% bracket covers income up to $12,400, the 12% bracket covers $12,401 to $50,400, and the brackets increase from there. The top 37% rate applies to taxable income above $640,600 (single) or $768,700 (married filing jointly). These brackets are from IRS Revenue Procedure 2025-32.
- What is the standard deduction for 2026?
- The 2026 standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, $16,100 for married filing separately, and $24,150 for head of household. These amounts were increased by the One Big Beautiful Bill Act (OBBBA) passed in July 2025. Taxpayers age 65 or older receive an additional $2,050 (single) or $1,650 per spouse (married).
- What is the difference between marginal and effective tax rate?
- Your marginal tax rate is the rate on your last dollar of income — it's the bracket you fall into. Your effective tax rate is your total tax divided by your total income. Because the US uses progressive brackets, your effective rate is always lower than your marginal rate. For example, even if your marginal rate is 22%, your effective rate on $75,000 might only be around 11-12% because the first portions of your income are taxed at 10% and 12%.
- Does this calculator include state income tax?
- No, this calculator computes federal income tax only. State income taxes are separate and vary by state. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no state income tax.
