How to Use This Federal Income Tax Calculator

Enter your annual gross income โ€” your total income before any deductions. Select your filing status (single, married filing jointly, married filing separately, or head of household). The calculator automatically applies the 2025 standard deduction, or switch to itemized if yours is higher.

Results update instantly: you'll see your total federal tax, effective rate (what you actually pay overall), marginal rate (your highest bracket), and after-tax income.

The Formula

Taxable Income = Gross Income โˆ’ Deduction (standard or itemized)
Federal Tax = Sum of (income in each bracket ร— bracket rate)
Effective Rate = Total Tax รท Gross Income ร— 100

Example

Sarah, Single, $85,000 salary in 2025:

Tax: $11,925 ร— 10% + $36,550 ร— 12% + $21,525 ร— 22% = $1,192.50 + $4,386 + $4,735.50 = $10,314
Effective rate: 12.1% | Marginal rate: 22% | After-tax: $74,686/year ($6,224/month)

Frequently Asked Questions

What are the federal income tax brackets for 2025?
The 2025 federal income tax brackets are: 10% on income up to $11,925 (single), 12% up to $48,475, 22% up to $103,350, 24% up to $197,300, 32% up to $250,525, 35% up to $626,350, and 37% on income above $626,350. Married filing jointly brackets are approximately double.
What is the standard deduction for 2025?
The 2025 standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. These amounts are subtracted from your gross income before tax brackets are applied.
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income โ€” the highest bracket you fall into. Your effective tax rate is your total tax divided by total income, which is always lower because lower portions of income are taxed at lower rates. For example, a single filer earning $100,000 has a 22% marginal rate but roughly 15% effective rate.
How does the progressive tax system work?
The US uses a progressive (marginal) tax system where different portions of your income are taxed at increasing rates. Only the income within each bracket is taxed at that bracket's rate โ€” not your entire income. So moving into a higher bracket only affects the additional dollars, not all your earnings.
Should I file as single or head of household?
Head of household offers wider brackets and a higher standard deduction ($22,500 vs $15,000). You qualify if you are unmarried, paid more than half the cost of keeping up a home, and have a qualifying dependent. This can save $1,000-3,000+ in taxes compared to filing as single.
