This IRS tax calculator estimates what you'll owe the federal government based on the same bracket structure, rates, and standard deduction figures published by the IRS for 2025 and 2026. It's built to give you a quick sanity check on your federal tax liability before you file or before year-end planning.
Where the Numbers Come From
Every year the IRS publishes a Revenue Procedure that sets the inflation-adjusted income thresholds for each of the seven tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) along with the standard deduction. For 2025 those figures were further increased by the One Big Beautiful Bill Act. This calculator keeps both the 2025 and 2026 numbers available so you can model either tax year.
How the Estimate Is Built
Enter your annual gross income, choose your filing status, and select whether you'll take the standard deduction or itemize. The calculator subtracts any pre-tax retirement contributions, applies your deduction, and then runs the result through the IRS bracket schedule to produce your estimated tax, marginal rate, and effective rate.
What This Estimate Does Not Include
Your actual IRS bill can differ from this estimate for several reasons: nonrefundable and refundable credits (Child Tax Credit, Earned Income Tax Credit, education credits) reduce tax owed but aren't modeled here; the Alternative Minimum Tax can apply at higher incomes; self-employed taxpayers also owe self-employment tax; and investment income may be taxed at separate capital gains rates.
