How it works
This calculator estimates your federal income tax based on your annual income, filing status, and optional 401(k) contributions.
The standard deduction and 401(k) contributions (if any) are subtracted from your annual income to determine your taxable income.
Taxes are then calculated using the progressive tax bracket system.
The effective tax rate is your total tax divided by your annual income.
This calculator provides a simplified estimate and does not account for all possible deductions, credits, or state taxes.

Understanding Your Tax Calculation
Taxable Income
This is your total income minus deductions and exemptions. Our calculator uses the standard deduction of $16,100 for singles, $32,200 for married couples filing jointly, and $24,150 for heads of household.
Tax Brackets
The U.S. uses a progressive tax system. Your income is divided into brackets, each taxed at a different rate. For 2026, the brackets for single filers are:
10% for income up to $12,400
12% for income between $12,401 and $50,400
22% for income between $50,401 and $105,700
24% for income between $105,701 and $201,775
32% for income between $201,776 and $256,225
35% for income between $256,226 and $640,600
37% for income over $640,600
Your effective tax rate is the average rate you pay on your total taxable income, which is typically lower than your highest bracket rate.
Credits vs. Deductions
While not factored into this basic calculator, it’s important to understand:
Deductions reduce your taxable income
Credits directly reduce your tax bill, dollar for dollar
For a more precise calculation, consider consulting a tax professional or using the IRS’s detailed worksheets.
Impact on Financial Decisions
Understanding your tax liability can significantly influence major financial decisions:
Retirement Planning: Contributing to a 401(k) lowers your taxable income. For 2026, you can contribute up to $24,500 ($32,500 if you're 50 or older, or $35,750 if you're 60 to 63).
Investment Strategies: Different types of investment income (qualified dividends, long-term capital gains) are taxed at lower rates than ordinary income.
Filing Status Changes: Getting married, having a child, or becoming head of household can shift your tax brackets and available deductions.
The One Big Beautiful Bill Act: Signed into law in 2025, this legislation made permanent the lower TCJA tax rates, increased the standard deduction, raised the child tax credit to $2,200 per child, and introduced a new $4,000 deduction for seniors age 65 and older.
Frequently Asked Questions About Income Tax
What are the federal income tax brackets for 2026?
For 2026, the seven federal tax rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single filers, the brackets are: 10% on income up to $12,400; 12% from $12,401 to $50,400; 22% from $50,401 to $105,700; 24% from $105,701 to $201,775; 32% from $201,776 to $256,225; 35% from $256,226 to $640,600; and 37% on income above $640,600. These reflect the OBBBA inflation adjustments.
What is the standard deduction for 2026?
The 2026 standard deduction is $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for heads of household. Taxpayers age 65 or older get an additional $2,050 (single) or $1,650 (married). A new enhanced deduction of up to $4,000 per person is also available for seniors with income under $75,000 ($150,000 for joint filers).
How do I calculate income tax for freelance or self-employment income?
For self-employment income, you pay both income tax and self-employment tax (15.3% on net earnings, covering Social Security and Medicare). Use Schedule C to calculate your business profit, then report this on your Form 1040. You can deduct half of your self-employment tax, plus business expenses like home office costs, equipment, and health insurance premiums.
What changed with the One Big Beautiful Bill Act?
Signed in 2025, the OBBBA made the lower TCJA tax rates permanent (they were set to expire after 2025). It also increased the standard deduction, raised the child tax credit to $2,200 per child (indexed to inflation going forward), boosted the SALT deduction cap to $40,400, introduced a new $4,000 deduction for seniors, and preserved the higher estate tax exemption at $15 million per person.
Can I use this calculator for state income tax estimates?
This calculator covers federal income tax only. State income taxes vary widely. Seven states (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming) have no state income tax, while others range from around 1% to over 13%. Check your state's tax authority website for a state-specific calculator.
How does a 401(k) contribution reduce my taxes?
Traditional 401(k) contributions are pre-tax, meaning they reduce your taxable income dollar for dollar. For 2026, you can contribute up to $24,500 ($32,500 if you're 50 or older, or $35,750 if you're 60 to 63). For example, if you earn $75,000 and contribute $10,000 to your 401(k), your taxable income drops to $65,000 before the standard deduction is applied.
