The U.S. uses a progressive tax system, meaning your income is divided into portions and each portion is taxed at a different rate. A common misconception is that earning more always results in all income being taxed at a higher rate — that is not how it works. Only the income within each bracket is taxed at that bracket's rate.
For example, a single filer earning $75,000 in 2025 does not pay 22% on the entire $75,000. They pay 10% on the first $11,600, 12% on the next $35,550, and 22% only on the income above $47,150 up to $75,000. The result is an effective tax rate of roughly 14–15%, even though their marginal rate is 22%.
The standard deduction is a fixed amount that reduces your adjusted gross income (AGI) without requiring you to track individual expenses. For 2025: $15,000 (single), $30,000 (married filing jointly), $22,500 (head of household). Itemize only when your qualifying expenses total more than these amounts. Major itemizable expenses include mortgage interest, state and local taxes (SALT, capped at $10,000), charitable donations, and unreimbursed medical costs above 7.5% of AGI.
Your marginal rate is the rate applied to your last dollar of income — the bracket you are in. Your effective rate is total tax divided by total income. It is always lower than your marginal rate because earlier portions of income are taxed at lower rates. The calculator displays both so you can see the full picture.
All taxable income before any deductions — wages, tips, bonuses, dividends, interest, capital gains, and self-employment earnings. This is your starting point.
Gross income minus above-the-line deductions — 401(k) or traditional IRA contributions, student loan interest, HSA contributions, and half of self-employment tax. AGI determines eligibility for many credits and deductions.
AGI minus either the standard deduction or itemized deductions. This is the amount on which your federal income tax liability is calculated.
Credits reduce your tax bill dollar-for-dollar. Deductions reduce taxable income, which in turn reduces your bill at your marginal rate. A $2,000 credit saves exactly $2,000 in taxes; a $2,000 deduction saves $440 if you are in the 22% bracket.
AGI with certain deductions added back. Determines eligibility for Roth IRA contributions, education credits, and other benefits. For most people, MAGI equals AGI.
If your employer withholds more federal tax than you owe, you receive a refund. If less is withheld, you owe the difference when filing. Use this calculator's result and compare it to your W-2 box 2 to estimate your refund or balance due.
A complete step-by-step example using real numbers — a single filer with $75,000 gross income in 2025.
Start with Gross Income
Annual gross income = $75,000
Subtract Above-the-Line Deductions (to get AGI)
Assume $3,000 traditional IRA contribution and no other adjustments. AGI = $75,000 − $3,000 = $72,000
Subtract the Standard Deduction
2025 standard deduction for single = $15,000. Taxable Income = $72,000 − $15,000 = $57,000
Apply the Tax Brackets to Taxable Income
10% on first $11,600 = $1,160
12% on $11,601–$47,150 = $35,550 × 12% = $4,266
22% on $47,151–$57,000 = $9,850 × 22% = $2,167
Total Federal Tax (before credits) = $1,160 + $4,266 + $2,167 = $7,593
Apply Tax Credits (if any)
No dependents in this example, so no Child Tax Credit. Final tax = $7,593
Practical scenarios where knowing your estimated tax liability makes a real difference.
If your tax calculator result is significantly different from your year-to-date withholding on your pay stubs, you may owe a large balance or receive a large refund. Either outcome can be avoided by filing a new W-4 with your employer to adjust withholding. The IRS Tax Withholding Estimator at irs.gov/W4app walks you through this process.
If you paid $12,000 in mortgage interest and $9,000 in property and state income taxes, your total SALT-plus-mortgage itemized deduction is $21,000 — well above the $15,000 single standard deduction. Adding charitable donations could push this higher. Run the numbers in the itemized mode above to compare. For married filers, the $30,000 standard deduction is harder to beat unless you have a larger mortgage or higher SALT payments.
The Child Tax Credit is worth up to $2,000 per qualifying child under 17. With two children, that is $4,000 off your tax bill. If the credit exceeds your liability, up to $1,700 per child is refundable via the Additional Child Tax Credit. Phase-outs begin at $200,000 for single filers and $400,000 for married filers. Enter your dependents in the calculator above to see the credit applied automatically.
Qualifying long-term capital gains (assets held more than one year) are taxed at preferential rates: 0% if your taxable income is below $47,025 (single, 2025), 15% up to $518,900, and 20% above that. Short-term gains are taxed as ordinary income at your marginal bracket. If you are near a bracket boundary, consider timing the sale of appreciated assets across tax years to minimize your capital gains tax rate.
If you are self-employed, your tax picture includes self-employment tax (15.3% on the first $176,100 of net earnings in 2025, covering Social Security and Medicare). Half of this is deductible above the line, reducing your AGI. You may also qualify for the Qualified Business Income (QBI) deduction — up to 20% of qualified business income — which further reduces taxable income. Freelancers typically pay quarterly estimated taxes to avoid underpayment penalties; the IRS Form 1040-ES provides worksheets for this.
Federal tax is only part of the picture. Your state income tax can add thousands to your annual bill.
Most U.S. states levy their own income tax on top of federal taxes. The rates and structures vary widely — from zero in nine states to over 13% in California. Unlike the federal system, some states use flat rates while others use graduated brackets similar to the IRS.
Consider a single filer earning $100,000. In Texas (no state income tax), total federal + state tax is approximately $15,600 (federal only). In California, adding a state effective rate of around 6–7% adds $6,000–$7,000, bringing the total tax burden to roughly $21,600–$22,600. Over a 10-year career, that difference in state tax alone exceeds $60,000. This is why many high earners factor state taxes heavily into relocation decisions.
Note: This LiteCalc calculator estimates federal income tax only. To estimate your total tax burden, add your state's income tax rate to the federal result. Most state revenue departments publish online tax calculators specific to their brackets.
Not all taxable income comes from wages. When entering your gross income, include all of the following if applicable:
Bank account interest and most dividends are taxed as ordinary income. Qualified dividends receive lower long-term capital gains rates if IRS holding-period rules are met.
Net rental income (after mortgage interest, repairs, depreciation, and property taxes) is taxed as ordinary income. Passive activity loss rules limit how much rental loss can offset other income.
Profits from selling assets held one year or less are taxed at ordinary income rates — the same as wages. These add directly to your gross income and push you into higher brackets.
Traditional IRA and 401(k) withdrawals are fully taxable as ordinary income. Roth IRA qualified distributions are tax-free. Required minimum distributions (RMDs) begin at age 73 for most accounts.
Answers to common questions about the 2025 federal income tax calculator and IRS filing rules.
Enter your gross annual income, select your filing status, choose standard or itemized deductions, and add any dependents. The calculator applies the 2025 IRS tax brackets to your taxable income and shows your estimated federal tax, effective rate, and marginal rate instantly.
For 2025, single filers pay 10% on income up to $11,600; 12% on $11,601–$47,150; 22% on $47,151–$100,525; 24% on $100,526–$191,950; 32% on $191,951–$243,725; 35% on $243,726–$609,350; and 37% on income above $609,350. These are marginal rates — only the income within each bracket is taxed at that rate, not your total income.
In 2025, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Itemize only if your qualifying expenses — mortgage interest, SALT (capped at $10,000), charitable donations, and medical costs over 7.5% of AGI — total more than your standard deduction. Most filers (roughly 90%) benefit more from the standard deduction.
Your marginal rate is the rate on your last dollar of income — the highest bracket you reach. Your effective rate is total tax divided by total gross income. It is always lower than your marginal rate because earlier portions of income are taxed at lower rates. A single filer at $75,000 has a 22% marginal rate but typically an effective rate of 10–15%.
The Child Tax Credit is worth up to $2,000 per qualifying child under 17 and reduces your tax liability dollar-for-dollar. Up to $1,700 per child is refundable. With two children, a $4,000 credit can eliminate most or all of the tax liability for a middle-income household. Phase-outs begin at $200,000 (single) and $400,000 (married filing jointly).
Gross income is total income from all sources. Adjusted Gross Income (AGI) is gross income minus above-the-line deductions — traditional IRA contributions, student loan interest, HSA contributions, and half of self-employment tax. AGI is the key figure that determines eligibility for many credits and deductions. Taxable income is AGI minus your standard or itemized deduction.
This calculator shows your estimated tax liability. To estimate your refund, look at box 2 (Federal Income Tax Withheld) on your W-2. If that amount is greater than this calculator's result, the difference is your approximate refund. If it is less, you may owe additional tax when filing. Adjusting your W-4 withholding during the year prevents large balances due.
You can enter self-employment income as your gross income. Note that self-employed individuals also owe self-employment tax (15.3% on the first $176,100 of net earnings, covering Social Security and Medicare). Half of this is deductible above the line and reduces AGI. The QBI deduction may also reduce taxable income by up to 20%. These additional calculations are best handled with professional tax software or a CPA.
This calculator uses current 2025 IRS tax brackets and standard deduction amounts, making it accurate for most standard W-2 scenarios. It may not fully account for AMT, passive income rules, NIIT, or specialized credits. Treat the result as a reliable estimate for planning purposes. For final filing accuracy, use IRS-approved software or consult a tax professional.
Yes. Most states impose a separate income tax. Nine states — Alaska, Florida, Nevada, South Dakota, Texas, Washington, Wyoming, and New Hampshire and Tennessee (on wages) — have no state income tax. States like California (up to 13.3%), New York (up to 10.9%), and Oregon (up to 9.9%) have significant rates that substantially increase total tax burden. This calculator estimates federal tax only.
