| Visualizing how the progressive tax system works: different income tiers are taxed at different rates. |
Hi everyone! Eliza here from Navigating Taxes.
Today we’re tackling one of the most important parts of the U.S. tax system: the federal income tax. This is the tax most workers pay, and understanding it is a big step in my learning journey—and maybe yours too.
Your Quick Recap: Where This Fits In
Before diving in, it helps to understand where taxes come from and the Social Security and Medicare taxes (FICA) that are also taken out of your paycheck.
What Is Federal Income Tax? Your Beginner's Guide
The federal income tax is a tax you pay on the money you earn. It helps fund government services and programs, such as national defense, infrastructure, healthcare, and education. The amount you owe depends on your income, filing status, and deductions. For an official explanation, the IRS has a helpful overview of how federal income tax works.
Understanding the Progressive Tax System
The U.S. uses a progressive tax system. This means the more you earn, the higher the tax rate on the top portion of your income. For example, the first portion of income might be taxed at 10%, the next portion at 12%, and so on. You can see the current IRS tax brackets and rates to understand how much of your income falls into each bracket.
Why Understanding This Matters to Your Paycheck
Federal income tax is one of the largest deductions from your paycheck. Understanding how it works gives you better insight into your personal finances and prepares you for making informed decisions in the future.
What’s Next: The Mystery of Tax Withholding
When you get paid, you don’t see your full salary because your employer withholds a portion for taxes. This is called tax withholding, and it explains why your paycheck often looks smaller than expected.
We’ll dive deeper into this in my next post: Tax Withholding: What It Is and Why It Matters for Your Paycheck.
