SSDI vs SSI. Same medical test. Everything else differs.
Both programs use the identical definition of disability. What separates them is your work record on one side, and your income and resources on the other.

Two programs, one medical standard
SSDI and SSI are run by the same agency and use the same definition of disability. The medical question is identical. Everything else about them is different.
SSDI is insurance. You paid for it through payroll taxes, and eligibility turns on your work record. SSI is a needs-based program funded by general tax revenue, and eligibility turns on how little income and how few resources you have.
Some people qualify for one. Some qualify for both, which is called a concurrent claim. Some are denied one and approved for the other.
| SSDI | SSI | |
|---|---|---|
| What it is | Insurance you paid into through FICA taxes | Needs-based assistance from general revenue |
| Work record required | Yes. One credit per $1,890 earned, four per year maximum. Generally 5 of the last 10 years. | No work history required at all |
| Do savings matter? | No. Assets and resources are irrelevant. | Yes. Countable resources are limited to $2,000 for an individual, $3,000 for a couple. |
| Does household income matter? | No | Yes. Your income and often a spouse’s reduces or eliminates the benefit. |
| Monthly amount | Based on your lifetime earnings record | Federal benefit rate of $994 for an individual, $1,491 for a couple, reduced by countable income |
| Waiting period | Five months. First payment for the sixth full month after onset. | None |
| Back pay before you applied | Up to 12 months of retroactive benefits | None. Payment cannot start before the application month. |
| Health coverage | Medicare, after a further waiting period | Medicaid, typically immediately in most states |
The retroactivity difference is easy to miss and it is worth real money. An SSDI claim can reach back up to twelve months before you filed. An SSI claim cannot reach back at all.
Which one applies to you
A rough guide. The only way to know for certain is to check your earnings record.
You worked steadily and stopped recently
You have a solid work history, you left the workforce within roughly the last five years, and you have savings or a spouse who works. SSDI does not care about any of that — only your work record and your medical evidence.
Little work history, few resources
You have not worked much, or not recently enough to stay insured, and you have minimal income and assets. SSI does not ask for a work record.
A small SSDI benefit
If your earnings record produces a low monthly SSDI benefit, SSI may top it up. These concurrent claims are common and worth filing correctly from the start.
One case we do not take
We represent claimants pursuing SSDI and SSI benefits. We do not handle overpayment matters or cessation cases — where benefits already awarded are being reduced or terminated. Those are a different practice and you deserve someone who does them every day.
Not sure which you should be filing?
Your earnings record answers most of this, and it is one of the first things we look at. Tell us what you have and we will tell you which program fits.
