💡 What Is Federal Income Tax?
Federal income tax is a tax levied by the U.S. government on the annual earnings of individuals, corporations, and other legal entities. It helps fund essential services such as Social Security, Medicare, the military, and public infrastructure.
In 2025, the IRS still uses a progressive tax system, meaning the more you earn, the higher the percentage of your income is taxed — but only within specific brackets.

📐 Federal Income Tax Rates: How They Work
The U.S. income tax system is marginal. That means you don’t pay the same rate on all your income. Here’s a quick example:
If you’re a single filer earning $60,000:
-
First $11,600 is taxed at 10%
-
Income from $11,601 to $47,150 is taxed at 12%
-
Income from $47,151 to $60,000 is taxed at 22%
You don’t pay 22% on the full $60,000 — only on the amount that falls within that bracket.
