A pay stub shows your gross pay for the period, itemized deductions (federal and state taxes, FICA, and benefit withholding), year-to-date totals for each line, and your net pay for the period. If any number looks wrong, the stub is where you catch it before it compounds over the year.
| Code / abbreviation | What it means |
|---|---|
| FED / FIT / Fed Tax | Federal income tax withheld |
| SS / OASDI / Soc Sec | Social Security tax (6.2% employee share) |
| MED / Medicare | Medicare tax (1.45% employee share) |
| SIT / State Tax | State income tax |
| YTD | Year-to-date total for that line |
| 401k / 403b | Pre-tax retirement contribution |
| HSA / FSA | Health savings or flexible spending account contribution |
| GTL | Group term life insurance (taxable if benefit exceeds $50,000) |
| EE / ER | Employee / Employer (portion of a shared cost) |
Imagine a biweekly pay stub for an employee earning $52,000 a year. Their gross pay for the period is $2,000. Here is what each line means:
| Line on stub | Amount | What it means |
|---|---|---|
| Regular Pay | $2,000.00 | 40 hours x $50/hour, or annual salary divided by 26 periods |
| FIT (Federal Income Tax) | -$168.00 | Estimated federal withholding based on W-4 and brackets |
| OASDI (Social Security) | -$124.00 | 6.2% of $2,000 |
| MED (Medicare) | -$29.00 | 1.45% of $2,000 |
| SIT (State Income Tax) | -$80.00 | 4% state rate on taxable wages (example) |
| Medical EE | -$65.00 | Employee share of health insurance premium (pre-tax) |
| 401K | -$80.00 | 4% pre-tax retirement contribution |
| Net Pay | $1,454.00 | Amount deposited to your account |
Tax rates and limits vary by year and state. The figures above are for illustration only and are not tax advice.
Start with gross pay: hourly workers should confirm hours multiplied by rate matches the earnings line. Then check each tax line against approximate expected percentages:
If federal tax looks too high or too low, revisit your W-4. See gross pay vs net pay for a worked example of how each deduction reduces take-home.
The year-to-date column accumulates each item from January 1 of the current year through this pay period. It is useful for several reasons:
Beyond paycheck verification, pay stubs serve as proof of income for rental applications, mortgage pre-approvals, auto loans, and certain government program eligibility checks. Most lenders ask for two to three recent stubs. Some payroll systems only keep stubs online for a limited number of pay periods, so it is worth downloading or printing each one and saving it somewhere secure. If you lose access to a stub, your HR or payroll department can usually reissue it, though that takes time. See all paycheck deductions explained for details on every line you might see.
Start with the pay period dates and gross pay at the top. Then read through each deduction line: federal tax, Social Security (6.2%), Medicare (1.45%), state tax, and any benefit deductions. Subtract all deductions from gross pay and the result should match the net pay shown. The YTD column shows cumulative totals for the year so you can track withholding over time.
Common codes include FED or FIT for federal income tax, SS or OASDI for Social Security, MED for Medicare, SIT or State for state income tax, and YTD for year-to-date. Benefit codes vary by employer but often include 401K, HSA, FSA, DENTAL, and VISION. When in doubt, ask your HR or payroll department for a code legend.
On a $300 paycheck, FICA alone is about $22.95 (6.2% Social Security plus 1.45% Medicare). Federal income tax withholding depends on your W-4 and annualized income, but at low wage levels it may be very small or zero if your total annual wages fall below the standard deduction. State tax adds more if your state has one. The paycheck calculator gives a precise figure.
Your pay stub tells you your gross pay for the period, how much was withheld for each tax and benefit, your net (take-home) pay, and your year-to-date totals. It is also a record of your earnings for loan applications, rental applications, and tax verification purposes.
