Social Security (OASDI) is one of the two FICA taxes deducted from every American worker's paycheck. For 2026, the wage base has increased again, meaning high earners will pay more in total Social Security tax.
2026 Social Security Quick Facts
| Parameter | 2026 Value |
|---|---|
| Employee tax rate | 6.2% |
| Employer tax rate | 6.2% (matching) |
| Self-employed rate | 12.4% |
| Wage base (cap) | $184,500 |
| Maximum employee tax | $10,918.20 |
| Maximum self-employed tax | $21,836.40 |
How the Wage Base Works
You only pay Social Security tax on earnings up to the wage base. Once your year-to-date earnings exceed $184,500, Social Security withholding stops for the rest of the year.
Example: If you earn $200,000/year:
- Social Security tax: $184,500 × 6.2% = $10,918.20
- You stop paying SS tax after reaching the cap (around late October for most high earners)
Historical Wage Base Increases
| Year | Wage Base | Increase |
|---|---|---|
| 2020 | $137,700 | +3.6% |
| 2021 | $142,800 | +3.7% |
| 2022 | $147,000 | +2.9% |
| 2023 | $160,200 | +8.9% |
| 2024 | $168,600 | +5.2% |
| 2025 | $172,200 | +2.1% |
| 2026 | $184,500 | +2.3% |
The wage base is adjusted annually based on the national average wage index.
Multiple Employer Situations
If you work two or more jobs simultaneously and your combined wages exceed $184,500, you may overpay Social Security tax. Each employer withholds independently, unaware of the other.
How to get it back: Claim the excess as a credit on your Form 1040, Schedule 3, Line 11. The IRS will refund the overpayment.
Self-Employment and Social Security
Self-employed individuals pay both the employee AND employer portions — a total of 12.4%. However, you can deduct 50% of self-employment tax on your Form 1040.
Effective self-employment Social Security rate: approximately 9.3% after the deduction.
Impact on Your Pay Stub
Your pay stub should show Social Security tax as a separate line item. Watch for:
- The deduction stopping mid-year once you hit the wage base
- Year-to-date totals matching the maximum ($10,918.20)
- Correct calculation at exactly 6.2% of gross pay
