How Does the Calculator Work?
This calculator estimates your 2026 federal income tax liability in several steps:
- Calculate AGI: Gross income minus pre-tax deductions (401(k), HSA, etc.).
- Apply Deduction: Either the standard deduction (based on filing status) or your entered itemized deductions.
- Determine Taxable Income: AGI minus the larger of standard or itemized deduction.
- Calculate Tax: Apply the 2026 marginal tax brackets to taxable income.
- Apply Credits: Subtract Child Tax Credit ($2,000 per child), Other Dependent Credit ($500 per dependent), EITC, and other credits.
- Add Self-Employment Tax: If applicable, 15.3% of self-employment income.
- Determine Amount Due/Refund: Subtract tax withheld and estimated payments from total tax.

How do I choose between standard and itemized deductions?
You should choose the deduction that gives you the larger benefit. The calculator will use the standard deduction by default, but you can toggle to itemized deductions and enter your total itemized amount (mortgage interest, state/local taxes, charitable contributions, etc.).
What is the difference between gross income and taxable income?
Gross income is your total income before any deductions. Adjusted Gross Income (AGI) is gross income minus pre-tax deductions. Taxable income is AGI minus your standard or itemized deduction. Your tax liability is calculated based on taxable income.
What is my marginal tax rate?
Your marginal tax rate is the rate applied to the last dollar of your taxable income. For example, if you're in the 22% bracket, that means your top portion of income is taxed at 22%, not all of your income. This calculator shows both your marginal and effective tax rates.
What is the effective tax rate?
Your effective tax rate is your total tax liability divided by your total income. It represents the average rate you pay on all your income and is typically lower than your marginal rate.
How does self-employment income affect my taxes?
Self-employment income is subject to self-employment tax of 15.3% (for Social Security and Medicare) in addition to regular income tax. Enter your self-employment income in the advanced options to include this calculation.
What is the difference between tax liability and tax due/refund?
Tax liability is the total amount of tax you owe for the year. Tax due/refund is your liability minus what you've already paid through withholding and estimated payments. A positive number means you owe more; a negative number means you'll get a refund.
Are these 2026 tax rates official?
Yes, the IRS released the official 2026 inflation adjustments in October 2025. These rates and brackets are based on IRS Revenue Procedure 2025-32 and apply to tax year 2026 (returns filed in 2027).

This calculator does not currently compute AMT. The AMT exemption for 2026 is $90,100 for single filers and $140,200 for married filing jointly. If your income is high or you have many deductions, you may be subject to AMT and should consult a tax professional.

How accurate is this calculator?
This calculator provides estimates based on publicly available IRS tax tables and formulas. It is accurate for typical scenarios but may not capture all deductions, phaseouts, credits, or special situations. Always consult a tax professional for your specific tax situation.
When do I file my 2026 taxes?
