Decoding Pay Stub Abbreviations and Codes

Pay stubs are packed with abbreviations that look like alphabet soup: FICA, OASDI, GTL, FIT, YTD. Each one stands for a specific earning, tax, or deduction — and once you know the vocabulary, your stub becomes easy to verify. Here's a glossary of the codes you're most likely to see.

Codes aren't standardized. Different payroll providers abbreviate the same thing in different ways, so treat this as a guide and check with your employer if a line is unclear.

Earnings codes

These appear in the earnings section and add up to your gross pay.

Two of these cause more confusion than the rest. OT has to be premium-rated rather than paid at the straight hourly figure — how to calculate overtime pay covers the multiplier and which hours qualify. And VAC / PTO is taxed as ordinary wages, not as some lighter category; is PTO taxed? explains why a lump-sum payout can still have more withheld than a normal check.

Tax withholding codes

These are the mandatory taxes pulled from your gross pay.

The "EE" you sometimes see (as in FED MED/EE) means employee — the portion you pay. An "ER" suffix means employer.

Why some taxes never appear

You won't find FUTA or SUTA on your stub. Those unemployment taxes are paid by your employer rather than withheld from you, so they don't belong in your deductions at all. Understanding payroll taxes covers who pays what.

Deduction and benefit codes

These come out after taxes or, for pre-tax benefits, before them.

• 401(k) — your retirement contribution. A separate employer match line (sometimes labeled with codes like MTCH or ER 401K) shows what your company adds — that's free money, not a deduction from your take-home.
• HSA / FSA — health savings or flexible spending account contributions (usually pre-tax).
• MED / DEN / VIS — medical, dental, and vision insurance premiums.
• GTL — Group Term Life. If your employer-paid life insurance exceeds $50,000 in coverage, the IRS treats the excess as imputed income, so it's added to your taxable wages even though no cash changes hands.
• GARN / LEVY — wage garnishments or tax levies ordered by a court or agency. These are court-ordered rather than chosen, and federal law caps how much can be taken — see wage garnishments on your pay stub.

The one code on every line: YTD

YTD stands for year-to-date — the running total of that earning, tax, or deduction since January 1. The YTD columns are how you confirm your withholdings are on track and how lenders verify steady income, so they matter just as much as the current-period numbers.

A quick sanity check

Once you can read the codes, verifying your stub takes seconds:

1. Add up the earnings codes — they should equal your gross pay.
2. Add up the tax and deduction codes.
3. Gross pay minus those deductions should equal your net pay.

If the math doesn't work, flag it with payroll. That three-line check is the same one covered in gross pay vs. net pay, and it's the single most reliable test of whether a stub is internally consistent.

Create a clearly labeled pay stub

If you're generating stubs for yourself, employees, or contractors, OakPaystubs itemizes every earning, tax, and deduction with clear labels and automatic YTD totals — so there's no guesswork about what each line means.
