OASDI is simply another name for Social Security tax. Whether your pay stub says OASDI, Social Security, or SS Tax — it’s the same 6.2% deduction funding your future retirement, disability, and survivor benefits.
What OASDI Stands For
| Letter | Word | Meaning |
|---|---|---|
| O | Old-Age | Retirement benefits for workers 62+ |
| A | And | — |
| S | Survivors | Benefits for families when a worker dies |
| D | Disability | Benefits for workers who become disabled |
| I | Insurance | It’s an insurance program, not a savings account |
The OASDI Rate
| Who Pays | Rate |
|---|---|
| Employee (you) | 6.2% |
| Employer | 6.2% |
| Self-employed | 12.4% (both halves) |
Example on a $2,000 paycheck:
- Your OASDI withholding: $124.00
- Your employer’s matching payment: $124.00
- Total contributed to Social Security: $248.00
Annual Wage Cap
You only pay OASDI on the first $176,100 earned in 2026:
| Earnings | OASDI Applies? |
|---|---|
| $1 - $176,100 | Yes, 6.2% |
| Above $176,100 | No — stops for the year |
What this means: Once your wages cross $176,100 in a calendar year, OASDI drops to $0 for the rest of the year. Your paycheck will be larger by 6.2% from that point until December 31.
| Annual Salary | OASDI Stops Around… |
|---|---|
| $200,000 | Early November |
| $300,000 | Mid-July |
| $500,000 | Late April |
How OASDI Affects Your Take-Home Pay
| Gross Paycheck | OASDI Withheld | Net After OASDI Only |
|---|---|---|
| $500 | $31.00 | $469.00 |
| $1,000 | $62.00 | $938.00 |
| $2,000 | $124.00 | $1,876.00 |
| $3,000 | $186.00 | $2,814.00 |
| $5,000 | $310.00 | $4,690.00 |
Remember, OASDI is just one of several taxes taken out — it stacks with Medicare, federal income tax, and state income tax.
What OASDI Buys You
Retirement Benefits
If you work 10+ years and contribute enough, you qualify for Social Security retirement benefits starting at age 62 (reduced) or full retirement age (66-67 depending on birth year).
Disability Insurance
If you become unable to work, OASDI contributions qualify you for Social Security Disability Insurance (SSDI).
Survivor Benefits
If you die, your spouse, children, or dependent parents may receive monthly benefits based on your earnings record.
The Earnings Record
Every dollar in OASDI you pay is tracked by the SSA. You can view your earnings history and estimated future benefits at ssa.gov/myaccount.
OASDI vs. Medicare on Your Pay Stub
| Item | Rate | Cap | What It Funds |
|---|---|---|---|
| OASDI | 6.2% | $176,100 | Retirement, disability, survivors |
| Medicare (HI) | 1.45% | None | Hospital insurance at 65+ |
Together, OASDI + Medicare = FICA (7.65% total).
OASDI for Self-Employed Workers
Self-employed individuals pay both halves of OASDI (12.4%), but they can deduct half as a business expense on their tax return, reducing their income tax burden.
| Situation | Your OASDI |
|---|---|
| Employee | 6.2% |
| Self-employed (gross) | 12.4% |
| Self-employed (after SE deduction) | ~9.3% effective |
Common OASDI Questions
Why did OASDI suddenly stop being deducted? You hit the annual wage cap. Once your year-to-date earnings exceed $176,100 (in 2026), OASDI stops until January 1. Enjoy the bigger paychecks — it’s not an error.
Why is my OASDI higher at my new job? If you changed employers mid-year, each employer starts fresh with the wage cap. You may overpay OASDI; if so, claim the excess as a credit on your federal tax return (Form 1040).
I’m exempt from OASDI — is that okay? Exemptions exist for certain student workers, specific visa holders, and some religious groups. If you see $0 OASDI but don’t fit these categories, contact HR — you may not be earning credits toward Social Security benefits.
Does OASDI count toward my Social Security benefit? Yes. Every dollar of wages subject to OASDI is tracked in your earnings record at ssa.gov. Higher lifetime earnings = higher benefits.
