How to Read Your Pay Stub: Understanding Every Line
How to Read Your Pay Stub
Most people glance at the net pay number and throw away the rest. Every other line on that stub tells you something important about your money, your taxes, and your benefits.
A pay stub is a financial snapshot that most Americans receive every two weeks and almost none of them fully understand. A 2023 survey by the National Payroll Institute found that over 50 percent of working Americans could not explain the difference between gross pay and net pay with confidence, and fewer than 30 percent could identify all the deductions on their pay stub by name. This matters because your pay stub is the primary document that shows you how much you are earning, how much the government is taking, what your employer is contributing to your benefits, and whether everything is calculated correctly.
Errors on pay stubs are more common than most people realize. Incorrect tax withholding, missing overtime, wrong benefit deductions, and misclassified employment status all happen regularly. If you cannot read your pay stub, you cannot catch these errors — and over a year, even a small recurring mistake can cost you hundreds or thousands of dollars. This guide walks through every line on a typical pay stub, explains what it means in plain English, and tells you what to look for to make sure you are being paid correctly.
Approximately 30 percent of your gross pay goes to taxes and deductions for a typical W-2 employee. Understanding where that 30 percent goes is the first step to making informed decisions about your withholding, benefits, and take-home pay.
Your pay stub is not just a receipt. It is a financial document that deserves the same attention as a bank statement.
Every Line on Your Pay Stub, Explained
Pay stubs vary in format by employer, but they all contain the same core information organized into three sections: earnings, deductions, and net pay. Here is what each line means:
Earnings Section
Gross Pay
Your total earnings before any deductions. For salaried employees, this is your annual salary divided by the number of pay periods (typically 24 or 26). For hourly employees, this is your hours worked multiplied by your hourly rate. This is the number your employer agreed to pay you — everything below reduces it.
Regular Hours / Salary
Your standard pay for the pay period. For hourly workers, this shows the number of regular hours (up to 40 per week) and the rate. For salaried workers, it shows the per-period amount.
Overtime (OT)
Hours worked beyond 40 in a week, paid at 1.5 times your regular rate (by federal law for non-exempt employees). If you worked overtime and this line is missing or calculated at the wrong rate, that is an error worth flagging immediately.
Tax Deductions
Federal Income Tax
The amount withheld for federal taxes based on your W-4 form (the form you filled out when you were hired that determines your withholding). This is not your actual tax bill — it is an estimate. If too much is withheld, you get a refund. If too little, you owe at tax time. The amount depends on your income, filing status, and allowances claimed.
State Income Tax
Withholding for your state’s income tax. This varies dramatically by state — some (like Texas, Florida, and Nevada) have no state income tax at all, while others (like California and New York) take 5 to 13 percent of your income. If you live in a no-income-tax state, this line will not appear.
Social Security (FICA – OASDI)
6.2 percent of your gross pay (up to the annual wage cap of $176,100 in 2026). Your employer matches this amount, so 12.4 percent total goes into Social Security. This funds your future retirement and disability benefits.
Medicare (FICA – HI)
1.45 percent of your gross pay with no wage cap. Your employer matches this too. High earners (over $200,000 for single filers) pay an additional 0.9 percent Medicare surtax. This funds healthcare for retirees.
Benefit Deductions
Health Insurance
Your share of health insurance premiums. Most employers pay 70 to 85 percent of the premium; you pay the rest, typically pre-tax (which reduces your taxable income). If you enrolled in a high-deductible plan with an HSA, the HSA contribution may appear as a separate line.
401(k) / Retirement
Your contribution to your employer’s retirement plan. Traditional 401(k) contributions are pre-tax (they reduce your taxable income now but you pay taxes when you withdraw in retirement). Roth 401(k) contributions are after-tax (no tax break now, but withdrawals in retirement are tax-free). If your employer offers a match, that match does NOT appear on your stub — it goes directly into your account.
Other Deductions
This may include dental and vision insurance, life insurance, disability insurance, FSA or HSA contributions, union dues, parking/transit benefits, or wage garnishments. Each should be listed separately with a clear label.
The Bottom Line
Net Pay (Take-Home Pay)
Gross pay minus all deductions. This is what gets deposited into your bank account. For most employees, net pay is 65 to 75 percent of gross pay. If the gap between your gross and net pay seems larger than expected, review each deduction line to understand where the money is going.
Year-to-Date (YTD) Column
Most pay stubs include a YTD column showing cumulative totals for the year. Check this against your W-2 at tax time — they should match. If they do not, there may be a payroll error. The YTD also helps you track whether you are approaching thresholds (like the Social Security wage cap or FSA limits).
What to Look For (Common Errors)
Pay Stub Error Checklist
| What to Check | Why It Matters | How to Spot It |
|---|---|---|
| Hours worked | Ensures you are paid for all time worked | Compare to your own records or time clock |
| Overtime rate | Must be 1.5x regular rate (if non-exempt) | Divide OT pay by OT hours |
| Tax withholding | Wrong W-4 info = owing money or large refund | Use IRS withholding estimator tool |
| Benefit deductions | Should match your enrollment elections | Compare to benefits enrollment confirmation |
| Pre-tax vs. post-tax | Pre-tax deductions save you money | Verify 401(k) and health insurance are pre-tax |
| YTD totals | Running total should be consistent | Multiply per-period amount by number of periods |
If You Find an Error
Contact your HR or payroll department immediately with your pay stub and a clear description of the discrepancy. Most payroll errors are corrected on the next pay cycle. Keep copies of all pay stubs — you may need them for tax disputes, loan applications, or employment verification. If errors persist after multiple requests, you can file a complaint with your state’s Department of Labor.
Smart Pay Stub Habits ✅
- Review every pay stub, not just the net pay
- Keep digital or physical copies for at least 1 year
- Compare YTD totals to your W-2 at year-end
- Update your W-4 after major life changes (marriage, kids, job change)
- Check that pre-tax deductions are actually pre-tax
- Verify overtime is at the correct 1.5x rate
Costly Mistakes 🚫
- Never looking at your pay stub
- Not updating your W-4 (leads to owing taxes or excessive refunds)
- Ignoring discrepancies in hours or overtime
- Not contributing enough to 401(k) to get the employer match (free money)
- Confusing gross pay with take-home pay when budgeting
- Throwing away pay stubs (keep for at least 1 year)
