How the federal tax calculator works
Enter your gross annual income and select your filing status. The calculator subtracts the 2025 standard deduction for your filing status to arrive at your taxable income.
Your taxable income is then run through the 2025 federal tax brackets. Because the US uses a progressive tax system, different portions of your income are taxed at different rates. Only the income that falls within each bracket is taxed at that bracket's rate.
The result shows your total federal tax, your effective tax rate (total tax divided by gross income), the standard deduction applied, and your taxable income. Open the band breakdown to see exactly how much tax you owe in each bracket.

What You Need to Know
The standard deduction is a flat amount the IRS lets you subtract from your gross income before calculating tax. For most people, this is simpler and more beneficial than itemizing individual deductions.
You should consider itemizing if your total deductible expenses (mortgage interest, state and local taxes up to $10,000, charitable contributions, medical expenses above 7.5% of AGI) exceed the standard deduction. About 87% of taxpayers use the standard deduction.
This calculator applies the standard deduction automatically. If you itemize, subtract your itemized total from your gross income and enter the result as your income for a more accurate estimate.
Marginal vs. effective tax rate
Your marginal tax rate is the rate applied to your last dollar of taxable income. If your taxable income puts you in the 22% bracket, your marginal rate is 22%.
Your effective tax rate is your total tax divided by your gross income. Because the US system is progressive, your effective rate is always lower than your marginal rate. For example, a single filer earning $75,000 has a marginal rate of 22% but an effective rate of roughly 11%.
Understanding both rates helps you make smarter decisions about retirement contributions, deductions, and tax planning.
Frequently asked questions
What are the 2025 federal income tax brackets?
For single filers: 10% up to $11,925, 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% above. Married filing jointly and head of household have wider brackets.
What is the standard deduction for 2025?
$15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. This is subtracted from gross income before tax brackets are applied.
What is the difference between marginal and effective tax rate?
Your marginal rate is the bracket your top dollar falls into. Your effective rate is your total tax divided by gross income. Because of progressive brackets, your effective rate is always lower than your marginal rate.
How do tax brackets work?
The US uses progressive taxation. You pay each bracket's rate only on the income that falls within that bracket. Moving into a higher bracket does not mean all your income is taxed at the higher rate.
Does this calculator include state income tax?
No, this shows federal tax only. State income tax varies widely. Some states like Texas, Florida, and Nevada have no state income tax, while California can add over 13%.
Should I use the standard deduction or itemize?
Most people benefit from the standard deduction. Itemize only if your deductible expenses exceed the standard deduction. About 87% of filers use the standard deduction.
What filing status should I choose?
Single if unmarried, Married Filing Jointly if married (usually the best option for couples), or Head of Household if unmarried and supporting a qualifying dependent in your home.
