Pay Stub Codes & Abbreviations Explained

Decode paystub codes and paycheck abbreviations: FICA HI, FIT/FWT, SIT, RES SIT, OASDI, MEDI, YTD, 401(k), deductions, taxes, and earnings.

Paystub abbreviations identify earnings, federal and state taxes, benefit deductions, retirement contributions, garnishments, reimbursements, and year-to-date totals. The same concept can appear under different payroll-system labels, so the code must be read in the context of the statement that uses it.

Start with the employer or payroll provider's legend, then compare the current amount, taxable wage base, rate or hours, and year-to-date column. Common federal labels include FIT or FWT for federal income tax, OASDI for Social Security, and MED or Medicare for Medicare tax.

A code guide can explain a label but cannot determine whether a deduction or tax is correct for a particular worker. Elections, benefits, plan documents, court orders, local rules, and payroll settings may control the actual entry.
