Free Tax Calculator 2026 – Estimate Income Tax from Salary
This free tax calculator estimates annual income tax liability based on your gross salary and filing status — updated for 2025 and 2026. It is a practical planning tool for employees, freelancers, and anyone who wants to understand how much of their income goes to taxes before reviewing an actual return or consulting a professional.
The calculator applies progressive tax brackets to your income, which means different portions are taxed at different rates. Only income above each bracket threshold is taxed at the higher rate — the first portion always stays at the lower rate. This free tax calculator estimator shows the correct breakdown across brackets so you understand your actual effective rate versus your marginal rate.
Results are estimates for planning purposes — not professional tax advice. The calculator runs entirely in your browser with no account or signup required.
