SSI is harder to get into than SSDI, mainly because of strict income and asset limits

If you're comparing Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI), the short answer is: SSI has tougher financial barriers. Both programs require you to have a severe medical condition that prevents substantial work, but SSI also counts your savings, your spouse's income, and your living situation against you. SSDI only looks at your work history and your medical condition — it doesn't matter if you have $100,000 in the bank.

The real difference comes down to what each program measures. SSDI asks: "Have you paid enough into Social Security through work?" SSI asks: "Are you poor enough, sick enough, and have few enough resources?" One is about your past contributions. The other is about your current financial desperation.

Key Takeaways

  • SSI counts your savings, your spouse's income, and your household resources against you; SSDI does not count any of these things.
  • SSI has a resource limit of $2,000 for an individual (as of 2024, though this varies by state); SSDI has no resource limit at all.
  • SSDI requires a work history and enough Social Security credits; SSI has no work requirement and is available to people who have never worked.
  • Both programs use the same medical standard — your condition must be severe enough to prevent substantial work — so the medical approval rate is similar for both.
  • You can receive both SSDI and SSI at the same time if your SSDI payment is very low, though this is uncommon.

How the resource limit makes SSI harder to enter

SSI has a resource limit — a cap on how much money and property you can own and still receive payments. For an individual, that limit is $2,000. For a married couple, it is $3,000. This includes savings accounts, checking accounts, stocks, and most other things you own. Your home and one vehicle do not count, but almost everything else does.

If you have $2,001 in savings, you are over the limit and ineligible. Some people spend down their savings deliberately — paying off debts, making home repairs, or buying a vehicle — to get under the limit. This is legal, but it means you have to be poor enough to may have access to.

SSDI has no resource limit. You could have $500,000 in the bank and still receive SSDI payments. The program does not care how much money you have; it only cares whether you paid into Social Security through work.

Why SSDI is easier if you have a work history

SSDI requires you to have worked and paid Social Security taxes for a certain number of years. The exact requirement depends on your age, but generally you need 40 credits, with at least 20 earned in the last 10 years. If you worked full-time for five years or more, you almost certainly have enough credits.

SSI has no work requirement at all. A person who has never worked — a young adult who became disabled before entering the workforce, or someone disabled since childhood — can receive SSI. But they must meet the resource and income limits, which SSDI applicants do not face.

This is why SSDI is often easier for working-age adults with a job history. If you have worked and paid taxes, SSDI asks only one question: "Are you disabled?" SSI asks three: "Are you disabled? Are you poor? And do you have few enough resources?"

Income limits and how they differ between the two programs

Both programs have income limits, but they work differently. SSI has a strict monthly income limit — in 2024, the federal payment is $943 per month for an individual, and your other income cannot exceed that amount. If you earn $100 per month from part-time work, your SSI payment drops by $100. If you earn $943 or more, you get no SSI payment at all.

SSDI also has an income limit, but it is much higher and applies only to work income. In 2024, if you earn more than $1,550 per month from work, you lose SSDI benefits. However, unearned income — money from savings, pensions, or other sources — does not count against SSDI at all. You can have $10,000 per month in pension income and keep your full SSDI payment.

This is another reason SSI is harder: it counts almost all income, while SSDI only counts work income. If you receive a pension, inheritance, or help from family members, SSI will reduce your payment. SSDI will not.

The medical approval process is the same for both programs

The medical standard is identical. Social Security uses the same list of severe conditions — called the Blue Book — to evaluate both SSDI and SSI applicants. Your condition must prevent you from doing substantial work, and it must last at least 12 months or result in death.

The approval rate for the medical part of the process is roughly the same for both programs. About 30 to 35 percent of initial applications are approved, and about 70 percent of appeals are approved. The difference is not in how hard it is to prove you are disabled; it is in the financial requirements that come before the medical review.

Many SSI applicants are denied not because their condition is not severe enough, but because they have too many resources or too much income. An SSDI applicant with the same condition would be approved, because SSDI does not count those resources or that income.

When you might receive both SSDI and SSI at the same time

It is possible to receive both programs simultaneously, though it is uncommon. This happens when your SSDI payment is very low — usually because you had a short work history or low wages — and you also meet the income and resource limits for SSI.

Social Security calls this "concurrent benefits." Your SSDI payment comes first, and then SSI tops it up to the federal minimum. For example, if your SSDI payment is $400 per month and the SSI federal rate is $943, you would receive $400 from SSDI plus $543 from SSI, for a total of $943.

This route is actually easier than SSI alone in one way: you do not need to prove a work history, because your SSDI (however small) establishes that you have one. But you still must meet all the SSI resource and income limits.

State variations in SSI payments and rules

SSI is a federal program, but many states add their own money on top of the federal payment. These state supplements vary widely. Some states add $50 per month; others add $200 or more. A few states add nothing.

Some states also have slightly different resource limits or rules about what counts as a resource. For example, a few states count vehicles differently or have different rules about in-kind support (when someone gives you food or shelter instead of money).

SSDI is entirely federal, so the payment and rules are the same everywhere. This is another small advantage for SSDI applicants: there is no state-by-state variation to navigate.

Frequently Asked Questions

Can I get SSI if I have a job?

You can receive SSI while working, but your payment will be reduced. Social Security excludes the first $65 of monthly earnings plus half of anything above that. If you earn $200 per month, your SSI payment drops by about $68. If you earn $943 or more, you receive no SSI payment that month.

Does my spouse's income count against my SSDI?

No. SSDI does not count your spouse's income at all. Your spouse's earnings, pension, or other income has no effect on your SSDI payment. SSI is different — a spouse's income is counted and can reduce your SSI payment.

What happens to my resources if I inherit money while on SSI?

An inheritance counts as a resource and will push you over the $2,000 limit. You would become ineligible for SSI. However, you can spend down the inheritance on allowed expenses — paying debts, making home repairs, buying a vehicle — and then reapply once you are back under the limit.

Is it faster to get approved for SSDI or SSI?

The timeline is roughly the same for both — usually three to six months for an initial decision, longer if you appeal. The difference is not speed; it is whether you face financial barriers before the medical review even begins.

Can I switch from SSI to SSDI later?

Yes. If you work and earn enough Social Security credits, you can later become may be able to access for SSDI. Social Security will automatically review your case when your work history changes. You would then receive SSDI instead of SSI, which means no more resource or income limits.
