How to Read Your Pay Stub (Line by Line)

Your pay stub is one of the most useful money documents you own, but the abbreviations and tax codes can make it look like a puzzle. Learning to read it takes about ten minutes, and it pays off: you'll catch payroll mistakes, understand why your take-home pay is smaller than your salary, and know exactly what to check before you file taxes or apply for a loan.

This guide walks through every section of a standard U.S. pay stub, what each line means, and the numbers worth double-checking every pay period.

The main sections of a pay stub

What Every Pay Stub Shows: Gross pay for the period, Taxes withheld, Other deductions, Net (take-home) pay, Year-to-date

Formats vary by employer and payroll provider, but nearly every pay stub is built from the same building blocks:

  • Pay period and pay date. The stretch of days you're being paid for, and the day the money hits your account. These are often different dates.
  • Gross pay. What you earned before anything is taken out.
  • Taxes. Federal, Social Security, Medicare, and usually state and sometimes local taxes.
  • Deductions. Health insurance, retirement contributions, and other items you or your employer set up.
  • Net pay. What actually lands in your bank account.
  • Year-to-date (YTD). Running totals for the year so far.

Gross pay vs. net pay

Gross Pay vs. Net Pay: Gross Pay vs Net Pay

Gross pay is your earnings before a single dollar is removed. For hourly workers, that's your hours multiplied by your rate, plus any overtime. For salaried workers, it's your annual salary divided by the number of pay periods in the year.

Net pay is the amount left after taxes and deductions. This is your take-home pay. The gap between the two often surprises people, and taxes are usually the biggest reason for it.

A quick sanity check: hourly workers can multiply their hours by their pay rate and confirm the total matches the gross pay on the stub. If you worked overtime, federal law generally requires 1.5 times your regular rate for hours over 40 in a workweek. The U.S. Department of Labor explains the overtime rules under the Fair Labor Standards Act.

Understanding the tax lines

Taxes are usually the largest slice taken out of your gross pay. Here's what the common abbreviations mean:

Federal income tax (FED, FIT, or FWT)

This is money withheld and sent to the IRS toward your federal income tax bill. The amount is based on the Form W-4 you filled out when you started, which tells your employer how much to withhold. If too much is taken out, you get a refund at tax time; if too little, you may owe.

Social Security and Medicare (FICA)

These two are payroll taxes required under the Federal Insurance Contributions Act. On many stubs they appear as "Social Security" and "Medicare," or together as "FICA." Your employer pays a matching share you don't see on the stub. The rates and the annual wage cap on Social Security are set by law and can change; the Social Security Administration publishes current figures.

State and local taxes

Most states have income tax withholding, shown as "State Tax" or your state's abbreviation. A handful of states have no income tax at all. Some cities and counties add local taxes. These vary widely, so check your state's tax agency for specifics.

Deductions: pre-tax vs. after-tax

Pre-tax deductions lower your taxable income But they shrink the gross figure taxes are calculated on

Deductions are amounts taken out for benefits and programs. They fall into two groups, and the difference matters for your taxes:

  • Pre-tax deductions come out before taxes are calculated, which lowers your taxable income. Common examples include traditional 401(k) contributions, health insurance premiums, HSA or FSA contributions, and some commuter benefits.
  • After-tax deductions come out after taxes. Examples include Roth 401(k) contributions, wage garnishments, union dues, and charitable giving through payroll.

You'll often see these listed with abbreviations like 401K, MED or MEDICAL (health premium), DEN (dental), VIS (vision), and HSA or FSA. If a code is unclear, your HR or payroll department can tell you exactly what it covers.

What "year-to-date" means and why it matters

The YTD column shows running totals from January 1 through the current pay period. It's easy to skip, but it's one of the most valuable parts of the stub. Your YTD gross should roughly match what will appear on your Form W-2 at the end of the year, and YTD tax totals help you gauge whether your withholding is on track. If your final pay stub of the year and your W-2 don't line up, that's worth raising with your employer before you file.

The numbers worth checking every pay period

  1. Hours and pay rate. Confirm your hours and rate are correct, especially after a raise or a busy overtime week.
  2. Gross pay math. Rate times hours (plus overtime) should equal gross pay.
  3. Deductions you signed up for. Make sure your 401(k) percentage and insurance premiums match what you elected.
  4. Net pay vs. your deposit. The net pay should match the amount deposited to your account.
  5. Filing status changes. After a life event like marriage or a new child, check that your withholding reflects your updated W-4.

If you think too much or too little federal tax is being withheld, the free IRS Tax Withholding Estimator can help you decide whether to submit a new W-4 to your employer.

What to do if something looks wrong

Start with your employer's payroll or HR department, since most stub errors are simple data-entry mistakes they can fix quickly. Keep copies of your stubs, because you may need them for loans, apartment applications, or to verify income. If you're paid on a payroll card and have questions about fees or access to your wages, the Consumer Financial Protection Bureau explains your rights around prepaid and payroll cards. For unpaid wages or overtime disputes, the Department of Labor's Wage and Hour Division is the agency to contact.

FAQ

Why is my take-home pay so much lower than my salary?

The difference is mostly taxes (federal income tax, Social Security, and Medicare) plus any pre-tax deductions like health insurance and retirement contributions. Add those up on your stub and they should account for the gap between gross and net pay.

Do I need to keep my pay stubs?

It's a good idea to keep them at least until you receive and check your annual W-2, and longer if you might need proof of income for a loan or lease. Many payroll systems let you download past stubs at any time, so check your employee portal.

What's the difference between my W-4 and my W-2?

You fill out a W-4 to tell your employer how much tax to withhold from each paycheck. Your employer sends you a W-2 after the year ends, summarizing your total wages and taxes withheld so you can file your tax return.

Which line to act on first

The stub tells you which door to knock on, and picking the wrong one costs you weeks.

  • If net pay doesn't match your deposit, or your hours and rate are off, start with payroll or HR. As stated above, most stub errors are simple data-entry mistakes they can fix quickly. Going to an agency first is the worse move here, because a typo in your rate is not a wage dispute.
  • If the hours are right but the money isn't — overtime hours over 40 in a workweek not paid at 1.5 times your regular rate, or wages missing outright — and payroll won't correct it, that's the Department of Labor's Wage and Hour Division. That's the escalation the body names for unpaid wages and overtime, not for coding errors.
  • If nothing is wrong and the gross-to-net gap is just larger than you expected, the lever is your W-4, not payroll. Run the IRS Tax Withholding Estimator first. The trade-off is direct: withhold less and your paycheck grows, but if too little comes out you may owe at filing instead of getting a refund.
  • If your final stub of the year and your W-2 don't line up, raise it before you file — your YTD gross should roughly match the W-2, and reconciling a return afterward is the harder path.

Other Structures Coverage: 10% Rule for Fences and Sheds

By Plain Money Guide · Researched from official sources · Checked 2026-08-11 · Editorial standards Coverage B pays 10% of your dwelling limit for the fence — the tree that broke it is a separate line. Your fence, shed and detached garage fall under Coverage B — usually 10% of your dwelling limit, and it's extra money, not carved out of Coverage A. That single sentence settles most of the arguments people have with adjusters after a summer storm. The rest of the arguments come from a different place: the tree that knocked the fence over is not covered by the same rule, is capped far lower, and on a standard policy is often not covered at all when wind is what felled it. Here is how the two rules stack, with the arithmetic carried through.
