US Tax System Overview

Understanding federal income tax, state taxes, and payroll deductions

The United States operates a progressive federal income tax system with rates ranging from 10% to 37% for 2025. Most Americans also pay state income taxes (rates vary by state), Social Security tax (6.2%), and Medicare tax (1.45%).

Federal Income Tax Brackets (2025)

The US federal tax system uses seven tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Your tax rate increases as your income rises through different brackets. For example, single filers pay 10% on income up to $11,000, then 12% on income between $11,001 and $44,725.

State Income Taxes

Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Other states have rates ranging from 1% to over 13% (California). Some states have flat rates while others use progressive systems.

Payroll Taxes

All employed Americans pay Social Security tax (6.2% up to $160,200 income cap) and Medicare tax (1.45% with no cap). High earners pay an additional 0.9% Medicare tax on income over $200,000 (single) or $250,000 (married filing jointly).

Standard Deduction

For 2025, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. Most taxpayers choose the standard deduction rather than itemizing deductions.
