Federal Income Tax Calculator 2026 – Estimate What You Owe with CalQora

CalQora's federal income tax calculator helps US taxpayers instantly estimate how much federal income tax they owe for 2026. Simply enter your income, filing status, and deductions, and get an accurate, real-time estimate based on the current IRS federal tax brackets — completely free, with no sign-up required.

Federal income tax is calculated using a progressive bracket system, meaning different portions of your income are taxed at different rates.
