Have you ever noticed a deduction labeled “OASDI” on your paycheck and wondered what it means? OASDI stands for Old-Age, Survivors, and Disability Insurance. It’s another name for Social Security and is a federal program designed to provide financial support for retirees, people with disabilities, and families of deceased workers.
The OASDI tax is part of the Federal Insurance Contributions Act (FICA) and helps fund this program. Employers, employees, and self-employed individuals contribute to OASDI to ensure financial security for millions of Americans. Let’s break down how it works and why it matters.
How OASDI Works
OASDI tax is collected from your paycheck to fund the Social Security program. Here’s how it works:
- Employers and employees share the responsibility: Employees pay 6.2% of their wages, and employers match this amount for a total of 12.4%.
- Self-employed individuals pay the full 12.4% themselves but can deduct half of it when calculating their taxable income.
For example, if your annual income is $50,000, you’ll pay $3,100 in OASDI tax, and your employer will contribute an additional $3,100.
These contributions go into two trust funds:
- The Old-Age and Survivors Insurance (OASI) Trust Fund supports retirees and their families.
- The Disability Insurance (DI) Trust Fund provides benefits to individuals with disabilities and their dependents.
Who Pays OASDI Tax?
Nearly everyone who earns a paycheck contributes to OASDI. Here are the key groups:
- Employees: OASDI tax is automatically deducted from your paycheck.
- Employers: They match the amount deducted from employees’ pay.
- Self-employed individuals: They pay the full 12.4% but can deduct half of it as a business expense.
Exemptions: Some people are not required to pay OASDI tax, such as:
- Members of certain religious groups.
- Non-resident aliens on specific visas (e.g., students or researchers).
- State and local government employees covered by alternative retirement systems.
