Federal Income Tax Calculator

Your marginal rate is not your real rate. An $85K single filer hits the 22% bracket but only pays an effective rate of about 15% because the first chunks are taxed at 10% and 12%. Plug in your gross income, filing status, deductions, and 401(k) contributions to see the actual tax per bracket, your true effective rate, and monthly take-home after federal tax.

2025 Federal Tax Brackets for All Filing Statuses

The U.S. uses a progressive tax system with seven brackets. Each bracket taxes only the income within its range, not your entire income. The rates are the same across all filing statuses—10%, 12%, 22%, 24%, 32%, 35%, and 37%—but the income thresholds differ significantly depending on whether you file as single, married jointly, married separately, or head of household.

Standard Deduction vs. Itemized Deductions

The standard deduction is a flat amount subtracted from your adjusted gross income before calculating tax. For 2025, it's $15,700 for single filers, $31,400 for married filing jointly, $15,700 for married filing separately, and $23,500 for head of household. About 87% of taxpayers take the standard deduction because it exceeds their total itemizable expenses.

Itemizing makes sense only when your combined deductible expenses exceed the standard deduction. The main itemized deductions are mortgage interest, state and local taxes (capped at $10,000 under SALT), charitable contributions, and medical expenses exceeding 7.5% of AGI. If you own a home in a high-tax state, have a large mortgage, or make significant charitable donations, run the numbers both ways.

Marginal vs. Effective Tax Rate Explained

Your marginal tax rate is the percentage applied to your last dollar of taxable income—the highest bracket you reach. Your effective tax rate is your total tax divided by total income. These two numbers are always different because of progressive taxation, and the effective rate is what actually matters for your budget.

Example: A single filer with $100,000 in taxable income lands in the 22% bracket. But they don't pay 22% on all $100K. The first $11,925 is taxed at 10% ($1,193). The next $36,550 at 12% ($4,386). The remaining $51,525 at 22% ($11,336). Total tax: $16,915. Effective rate: 16.9%—well below the 22% marginal rate.

This is why moving into a higher bracket doesn't mean your entire income gets taxed more. Only the income above the bracket threshold faces the higher rate. A $1,000 raise that pushes you from the 22% to 24% bracket means only those extra dollars are taxed at 24%—not your whole paycheck.

Self-Employment Tax: What Freelancers and Contractors Owe

Self-employed individuals pay both the employer and employee shares of Social Security and Medicare taxes, totaling 15.3% on net self-employment earnings. Social Security tax (12.4%) applies to the first $176,100 of earnings in 2025. Medicare tax (2.9%) has no cap. You pay these on 92.35% of your net SE income, not the full amount.

The SE tax is in addition to federal income tax. On $100,000 of self-employment income, the SE tax is about $14,130. The silver lining: you can deduct half of the SE tax ($7,065) from your adjusted gross income, which reduces your income tax. You also reduce your taxable SE base by the 7.65% employer-equivalent portion before calculating the tax.

An additional 0.9% Medicare surtax kicks in on earnings above $200,000 for single filers ($250,000 married filing jointly). Self-employed workers should make quarterly estimated tax payments to avoid underpayment penalties—the IRS expects you to pay at least 90% of your current-year tax or 100% of last year's tax throughout the year.
