Income Tax Calculator
Quickly estimate your income tax based on gross income and a flat effective rate. Free tax calculator for budgeting and paycheck planning.
An income tax calculator provides a quick estimate of your federal tax liability based on your gross income, deductions, and an effective tax rate. It is not a full tax return — it uses a simplified flat-rate model — but it is remarkably useful for paycheck planning, budgeting, and "what-if" scenarios. Enter your gross annual income, the standard or itemized deduction you expect to claim, and the effective tax rate that applies to your income bracket. This tool helps you answer practical questions: how much will my take-home pay change if I get a raise? How much should I set aside for taxes as a freelancer? What is the tax impact of a larger 401(k) contribution (modeled as increased deductions)? All calculations are private and no income data is ever stored or transmitted.

How the calculation works
This calculator uses a simplified tax model: taxable income = max(gross income − deductions, 0); tax owed = taxable income × effective tax rate ÷ 100; net income = gross income − tax owed. For example, $75,000 gross with a $14,600 standard deduction yields $60,400 taxable income. At a 22% effective rate, tax = $60,400 × 0.22 = $13,288, net = $75,000 − $13,288 = $61,712. The effective rate represents the blended tax rate across all brackets, not the marginal rate of the highest bracket.
