Introduction: Why Pay Stub Abbreviations Matter

For many US employees, reading a paycheck can feel overwhelming. Rows of letters such as FICA, YTD, and MED appear without explanation. These pay stub abbreviations are more than payroll codes—they determine how your gross pay is calculated, how taxes are withheld, and what net pay you actually receive. Understanding them is essential for tax filing, financial planning, and ensuring paycheck accuracy. For comparison, you can also view a regular pay stub to see these terms in context.

What Are Pay Stub Abbreviations?

Pay stub abbreviations are shortened forms of payroll and tax terms designed to keep pay stubs concise. They may look confusing to beginners, but they reveal vital information about your income, deductions, and benefits. Whether you are paid hourly or salaried, you will see these abbreviations listed each pay period to explain where your money goes.

Common Pay Stub Abbreviations Explained

1. FICA

FICA stands for the Federal Insurance Contributions Act. It includes Social Security and Medicare taxes. These deductions fund retirement and healthcare benefits for US workers.

6. GROSS

Gross Pay is your total income before deductions. It may include salary, hourly wages, overtime, or bonuses.

7. FED
