Paystub Codes Explained: Complete List of Abbreviations [2026]

Your paystub is more than just a check—it's a detailed receipt of your earnings and taxes. However, space constraints often force payroll companies to use cryptic abbreviations. This guide translates the most common codes found on US paystubs so you know exactly where your money goes.

Important: Always review your paystub codes carefully each pay period. Catching a deduction error early can save you from tax headaches at the end of the year.

Common Questions About Paystub Codes

What is YTD?

YTD stands for Year-to-Date. It shows the total amount for a specific category (like Gross Pay, Federal Tax, or 401k contributions) from the beginning of the calendar year up to the current pay period. This number is crucial for verifying your annual income when applying for loans or apartments.

Why do I see FICA and OASDI?

Sometimes these taxes are listed separately, and sometimes they are combined. FICA is the federal law that mandates the tax. OASDI (Social Security) and MED (Medicare) are the specific taxes mandated by FICA. Seeing both FICA-SS and FICA-MED on the same paystub is completely normal.

What is IMP?

IMP usually stands for Imputed Income. This is the value of non-cash benefits (like group term life insurance over $50,000) that the IRS considers taxable income. It adds to your taxable wages so the government can tax it, but it doesn't actually increase your take-home cash.
