Both Medicare and Social Security are part of the FICA tax, but they serve different purposes and are withheld at different rates.
| Feature | Social Security | Medicare |
| Tax Rate | 6.2% of wages (up to the annual wage base limit) | 1.45% of all wages (no cap) |
| Additional Tax | None | Extra 0.9% for high earners |
| Purpose | Provides retirement, disability, and survivor benefits | Provides healthcare coverage for seniors (65+) and certain disabled individuals |
| Wage Base Limit (2024) | $168,600 | No limit |
Key Takeaway
- Social Security helps replace income in retirement or in case of disability.
- Medicare ensures access to healthcare when you’re older or disabled.
- Both contributions are required and appear as separate deductions on your pay stub for clarity.
