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 or Federal Tax) from the beginning of the calendar year up to the current pay period. This is crucial for verifying your annual income for loans.

Why do I see FICA and OASDI?

Sometimes they are listed separately, sometimes combined. FICA is the 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 is common.

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 but doesn't increase your take-home cash.
