Most people look at the bottom line — the net pay — and file the rest away. But the lines above it contain real information: how much you paid in taxes, whether your retirement contributions are on track, and what you’re actually taking home. Here’s how to read a pay stub from top to bottom.
What Is a Pay Stub?
A pay stub is a record of your earnings and deductions for a single pay period. It may be attached to a physical paycheck, delivered separately, or available through your employer’s payroll portal. You might see it called an earnings statement, wage statement, or payslip — these all refer to the same document.
Pay stubs serve two purposes: they confirm what you were paid, and they show how your gross pay was reduced to arrive at your net (take-home) pay.
The Header: Your Basic Information
At the top of most pay stubs, you’ll find your name and address (sometimes an employee ID), your employer’s name and address, the pay period (the date range the paycheck covers), and the pay date (the actual date the check was issued or your direct deposit landed).
It’s worth checking these details. Errors here — wrong name, wrong pay period — can signal a payroll mistake worth investigating.
Gross Pay
Gross pay is your total earnings before anything is taken out. How it’s calculated depends on how you’re paid:
- Hourly: hours worked multiplied by your hourly rate. Overtime (hours over 40 per week) is typically paid at 1.5 times your regular rate.
- Salaried: your annual salary divided by the number of pay periods in the year — usually 26 for biweekly pay, 24 for semimonthly.
- Commission or bonus: shown as a separate line item, added to your base pay for the period.
Gross pay is the number your employer reports to the IRS and uses as the starting point for all tax calculations.
Deductions
This is where most of the complexity lives. Deductions fall into two types: those taken before taxes are calculated (pre-tax) and those taken after (post-tax). The difference matters because pre-tax deductions lower your taxable income — meaning you pay less in federal and state income tax on that money.
Taxes
Every employee pays these federal taxes, which appear as separate line items on your stub:
- Federal income tax — withheld based on your W-4 filing status. The amount varies person to person; your employer uses IRS withholding tables to calculate it.
- Social Security tax — 6.2% of your gross wages, up to an annual wage ceiling ($176,100 in 2025). Your employer matches this amount.
- Medicare tax — 1.45% of all wages, with no income cap. Employees earning above $200,000 pay an additional 0.9% on wages above that threshold.
Depending on where you live, you may also see state income tax and, in some cities, local income tax withheld as additional line items.
Pre-Tax Benefit Deductions
These come out before taxes are calculated, which reduces the income you’re taxed on. Common pre-tax deductions include:
- Health, dental, and vision insurance premiums — your share of employer-sponsored coverage
- 401(k) or 403(b) contributions — retirement savings through your employer’s plan
- Health Savings Account (HSA) — if you have a high-deductible health plan
- Flexible Spending Account (FSA) — for qualified medical or dependent care expenses
Post-Tax Deductions
These come out after taxes are calculated and don’t reduce your taxable income. Examples include Roth 401(k) contributions (taxed now, tax-free in retirement), certain life or disability insurance premiums, union dues, and wage garnishments for things like child support or unpaid debts.
Net Pay
Net pay is gross pay minus all deductions — the amount that actually lands in your bank account. If your net pay seems off, check your math rather than assuming the payroll system got it right. Verify that your hours are correct, your benefit deductions match what you enrolled in, and your tax withholding reflects your current W-4.
Year-to-Date Figures
Most pay stubs include a year-to-date (YTD) column alongside the current period figures. These running totals show how much you’ve earned, paid in taxes, and contributed to benefits since January 1.
YTD figures are useful in a few specific ways. Your YTD federal tax withheld gives you an early read on whether you’re likely to owe or get a refund. Your YTD 401(k) contributions show whether you’re on track to hit your annual goal. And if you’re a higher earner, your YTD Social Security wages show how close you are to the wage cap, after which Social Security withholding stops for the year.
Using Your Pay Stub for Budgeting
Your pay stub is the foundation of a realistic budget. The number to build from is net pay — not gross. It’s easy to lose track of what you actually bring home when you think in terms of annual salary.
A few things worth reviewing when you look at your stub:
- Withholding too high or too low? A large tax refund isn’t a bonus — it means you’ve been giving the IRS an interest-free loan. Update your W-4 with HR if you consistently get a large refund or owe at tax time.
- Leaving a 401(k) match on the table? If your employer matches contributions up to a certain percentage and you’re contributing less than that, you’re forfeiting part of your compensation.
- Benefits costs adding up? Health insurance premiums, FSA contributions, and other deductions are easy to forget about once payroll is set up. Reviewing them periodically helps you make informed decisions at open enrollment.
How to Catch Errors
Payroll errors happen more often than most people realize. Common ones include the wrong number of hours (especially for hourly workers), a missing overtime payment, a raise that wasn’t updated in the system, benefit deductions that don’t match your elections, or state taxes withheld for the wrong state.
If something looks off, start with your employer’s HR or payroll department — most errors can be corrected in the next pay cycle. Keep your pay stubs on file at minimum until you receive your annual W-2, which summarizes the full year and is what you’ll actually use to file your taxes.
Understanding your pay stub doesn’t require an accounting background. Once you know what each section represents, a two-minute review each pay period is enough to catch problems early and stay on top of where your money is going before it reaches your account.
