How Progressive Income Taxes Work

How It Works

This tax calculator estimates US federal income tax for a single filer using the 2026 progressive bracket system. Your taxable income is divided into segments, with each segment taxed at its corresponding rate rather than taxing your entire income at a single rate. It does not include credits, payroll taxes, state taxes, or local taxes.

How to Use

1. Enter your Annual Taxable Income (gross income minus standard deductions). 2. The system automatically processes the income through the progressive brackets. 3. Review your take-home pay, total tax paid, and the breakdown of each bracket applied.

Understanding the Results

Net After Federal Income Tax is your taxable income less estimated federal income tax only. Income Tax Paid is the total tax owed. Effective Tax Rate is the average rate you pay (Total Tax / Taxable Income), which is always lower than your highest marginal tax bracket.

Progressive Tax FAQ

FAQ

What is the difference between marginal tax rate and effective tax rate?

Your marginal tax rate is the rate applied to the last dollar you earn (the highest bracket your income reaches). Your effective tax rate is the actual percentage of your total income paid in taxes, which is the average of all brackets.

Does moving into a higher bracket reduce my take-home pay?

No. Only the income that falls within the higher bracket is taxed at the higher rate. The income in the lower brackets remains taxed at the lower rates, so earning more always increases your net take-home pay.
