Understanding Your Paycheck: FICA, Federal Taxes, and Net Pay
When you land a new job offering $60,000 a year, or a promotion bumping you to $25 an hour, the first question you likely ask yourself is: "How much of that will actually hit my bank account?"
Decoding a US paycheck can be confusing. Your "Gross Pay" is the large number you agreed to when you were hired, but your "Net Pay" (your take-home pay) is what you actually get to spend after the government takes its share.
Let's break down exactly where your money goes.
What is FICA?
FICA stands for the Federal Insurance Contributions Act. It is a mandatory payroll tax deducted from almost every paycheck in the United States.
The standard FICA rate is 7.65% of your gross income. This money is split into two programs:
- Social Security (6.2%): Funds retirement and disability benefits.
- Medicare (1.45%): Funds healthcare for people over the age of 65.
(Note: Your employer also pays a matching 7.65% on your behalf, meaning the government actually collects 15.3% total).
Federal Income Tax Brackets
Unlike FICA, which is a flat percentage, the US Federal Income Tax system is "progressive." This means you don't pay one single tax rate on your entire income. Instead, your income is divided into "brackets," and each chunk of money is taxed at a different, progressively higher rate.
Before taxes are calculated, the IRS grants everyone a "Standard Deduction" (around $14,600 for a single filer). You do not pay any federal income tax on this initial amount. Only your income above the standard deduction is run through the tax brackets (10%, 12%, 22%, etc.).
