What is a Pay Stub?
A pay stub (or payslip) is a document given to an employee at the end of a pay period. It details the amount of money earned and the taxes and deductions taken out. Understanding your pay stub is crucial for ensuring you are paid correctly and for managing your personal finances.
Key Components of a Pay Stub
- Gross Pay: This is the total amount you earned before any taxes or deductions. If you are hourly, it's your hourly rate multiplied by the hours worked. If you are salaried, it's your annual salary divided by the number of pay periods.
- Federal Income Tax (FIT): The amount withheld for federal taxes, based on the information you provided on your W-4 form.
- State Income Tax (SIT): The amount withheld for state taxes. Not all states have an income tax.
- FICA (Social Security and Medicare): The Federal Insurance Contributions Act requires a 7.65% deduction from your gross pay (6.2% for Social Security and 1.45% for Medicare).
- Pre-Tax Deductions: These are deductions taken out before taxes are calculated, which lowers your taxable income. Examples include 401(k) contributions, health insurance premiums, and HSA contributions.
- Post-Tax Deductions: Deductions taken out after taxes have been calculated, such as union dues or wage garnishments.
- Net Pay: This is your "take-home pay"—the amount you actually receive in your bank account or paycheck.
Why You Should Check Your Pay Stub
Errors happen. Checking your pay stub ensures that your hours were recorded correctly, your tax withholdings are accurate, and your benefits are being properly funded. If you notice a discrepancy, contact your HR or payroll department immediately.
