Why is my paycheck smaller than my salary?
Your salary is gross pay. Before it reaches your bank, employers take out federal income tax (based on your W-4), Social Security (6.2%), Medicare (1.45%), any state and local taxes, plus benefits like health insurance and 401(k) savings. What’s left is net pay. Check your pay stub, and use the IRS withholding estimator to adjust your W-4.
Your checklist
- Know your gross vs net pay
- Understand the tax lines
- See which benefits come out
- Get your full 401(k) match
- Read every pay stub
- Check your W-4 with the IRS estimator

Gross vs net
Gross pay is your pay before anything comes out. Net pay is what lands in your bank. Example: $52,000 a year, paid every two weeks, is $2,000 gross per paycheck.
Taxes
- Federal income tax: based on the W-4 you filled out.
- Social Security: 6.2% of your pay, up to a yearly limit.
- Medicare: 1.45%.
- State and local tax: depends on where you live and work; some states have none.
Benefits and savings
Health, dental and vision insurance often come out before taxes, lowering your tax bill. Money you put in a 401(k) is still yours. If your employer matches, try to contribute at least enough to get the full match.
Your W-4
Too little withheld can mean a tax bill in April. Too much means smaller checks now and a refund later. The IRS Tax Withholding Estimator helps you get it close.
Your first paycheck
It may cover only part of a pay period or arrive later than expected.

Common questions
Is it better to get a big tax refund?
A big refund means you had extra taken out all year. Some people like it as forced savings; others prefer more money in each paycheck. More ›
Why did my paycheck change when nothing else did?
Common reasons are a new benefits year, a change in tax tables, hitting the Social Security yearly limit, or a different number of hours or pay days. More ›
What is FICA on my paycheck?
FICA is Social Security (6.2%) plus Medicare (1.45%), 7.65% in total for most employees. Your employer pays the same amount on top. More ›
How do I fill out a W-4 for my first job?
Most single people with one job can fill in their personal information, sign it, and skip the rest. If you have more than one job or a spouse who works, use the IRS Tax Withholding Estimator. More ›
What is a 401(k) match?
Extra money your employer adds when you save, like 50 cents for each dollar up to a limit. Not getting the full match leaves money on the table. More ›
Why is my first paycheck smaller than the rest?
It often covers only the days you worked in that pay period, and some employers pay a period behind. More ›
