SSDI vs. SSI: What’s the Difference and Who Qualifies?

If you are unable to work because of a medical condition, there’s a good chance you qualify for benefits through Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI). Millions of Americans with disabilities get benefits from these programs administered by the Social Security Administration. Monthly payments and eligibility for health insurance from the U.S. government can be lifesaving for you and your family. Learn all about the available programs, qualifications, and application processes below. We’ll help you figure out which program is right for you.

Key takeaways

1. SSDI and SSI are the two main Social Security disability programs. Both programs provide monthly payments to people who cannot work because of a long-term medical condition.

2. SSDI is based on your work history. You may qualify for SSDI if you worked and paid Social Security payroll taxes for several years before becoming disabled.

3. SSI is based on financial need. SSI helps people with disabilities who have little income and few assets, even if they have not worked much.

4. Some people qualify for both programs. If you meet the work requirements for SSDI and the financial limits for SSI, you may receive benefits from both programs.

What are Social Security disability benefits?

The Social Security Administration (SSA) oversees two programs that provide benefits to people with disabilities: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). These government programs support Americans who are unable to work due to a qualifying medical condition. When someone says they’re “on disability,” they usually mean they are getting benefits from one of these programs. In 2024, about 14 million Americans received some form of disability benefits administered by the Social Security Administration. SSDI and SSI both provide monthly benefits checks and health care coverage, but the eligibility requirements, qualifications, and benefits amounts differ.

SSDI qualifications

To qualify for Social Security Disability Insurance benefits, you must meet the medical and non-medical requirements:

• You must be disabled under government rules. The SSA considers you disabled if you cannot hold a job for at least a year because of a medical condition in the SSA Blue Book. To prove you meet this requirement, your medical records must include specialist treatment.

• You must have worked and paid taxes for years. Generally, you need 40 work credits to be eligible for benefits. Here’s a good rule of thumb: If you’ve worked at least five of the last ten years and paid taxes, you probably meet this qualification.

SSI qualifications

The eligibility requirements for the Supplemental Security Income include the following:

• You must meet the SSA’s definition of disabled. The government has a specific definition of disability. To be eligible for benefits, you must not be able to sustain employment for at least a year because of an impairment or medical condition.

• You must have very few assets. If you have less than $2,000 (or $3,000 if you are married), you probably qualify. You should count any money you have and other large assets, like a retirement account. Your home, one vehicle, and a few other unusual assets do not count.

• You have very little income from any source. Every dollar you or your spouse makes in income will decrease the amount you will receive from SSI. The government counts almost anything as income, including help you may be getting that’s not in cash, like if you live with friends rent-free. As a general rule, if you don’t have much cash coming in and you aren’t getting a huge amount of help from others, you’ll probably qualify.

Qualifying for either program is never easy: The government treats claims with suspicion and rejects most applicants. But if you meet the criteria above, you can likely get benefits with the right help.

SSDI vs. SSI benefits: what are the differences?

SSDI and SSI both offer monthly benefits and access to health insurance, but there are key differences. In short, SSDI eligibility has work requirements, and SSI is a needs-based program. Other differences include:

How much does Social Security disability pay in 2026?

Every year, inflation and cost-of-living adjustments increase the value of Social Security benefits. The maximum amount of benefits is as follows:

• Social Security Disability Insurance: In 2026, the maximum SSDI payment you can get is $4,152 per month.

• Supplemental Security Income: The maximum SSI payment for 2026 is $994 per month for an individual and $1,491 per month for a couple. 

It’s important to note that disability payments might offset other benefits, but only if you get more from Social Security. For example, if you are getting $200 in food stamps and you are awarded $1,000 in disability benefits, you may lose your food stamps. But you won’t end up with less money each month.

Should I apply for Social Security benefits?

If you are eligible for SSDI or SSI, or both, you should apply. There is no cost to submit an application. Apply as soon as it is clear that your condition will last a full year and that you have the medical evidence to prove it. 

Sometimes, that takes a while to figure out: your doctor may need to run tests and try a variety of treatments before they know how long your condition will last. Other times it is clear right away that a disability is long-lasting. Once your doctor is pretty sure your condition is going to keep you out of work for a full year, there is no reason to wait.

Can I get both SSDI and SSI benefits?

Yes, you can qualify for both SSDI and SSI benefits. If you are eligible for both programs, you should apply for both. There are two advantages:

1. You might get more in monthly payments if you need additional financial support.

2. There are waiting periods for SSDI, but not for SSI. If you are awarded benefits right away, you may still have to wait for your first check from SSDI. If that happens, getting an SSI check in the meantime can be a lifesaver.

How does the application process work?

The disability application process takes time and effort, so it’s important to understand the steps. There are two major stages in the process, and most people go through both:

1. Submit an initial application: You submit a lengthy written application, details on past work and treatment, and copies of your medical records online or at your local Social Security office. A government staffer reads your file and makes a decision. (Only 20% of people win at this stage — the large majority are denied.)

2. File an appeal: If you lose, you appeal your denial and eventually get a hearing with a judge. At the disability hearing, you get to submit additional evidence, speak to the judge directly, and cross-examine government experts. (Among people who make it to this stage, about 50% win. If you lose, there are several more stages of appeal.)

The government fears that people will exaggerate their medical problems to get free money. To win, you have to prove — beyond a doubt — that your medical condition is severe and disabling through your application.

How long does the application process take?

After submitting an application, it can take 3-6 months to get an initial decision, and 1-2 years (or more) to get a disability hearing. Even a small mistake or omission (such as a doctor failing to send in records or a bad answer on a form) can doom an application. 

The good news is that once you win — even if it takes a long time and several appeals — you get back pay or retroactive benefits for the time you should have been getting benefits.

Do I need a lawyer to apply for disability?

The most successful applicants get a lawyer or trained non-lawyer representative to help with the disability application process. Applicants who work with a lawyer at the hearing stage are three times more likely to qualify for disability benefits. Lawyers will gather your medical records, help you complete your application, advise you on getting proper medical treatment, submit all the paperwork, and, if needed, argue your case before a judge. There are some cases in which you might consider applying on your own:

• Your medical condition is severe. If you’re seeing a specialist often, have extreme limitations, and haven’t worked in years, you can likely win benefits on your own. You can automatically qualify for disability if your severe or terminal medical condition is on the Compassionate Allowance List.

• You can’t convince a lawyer to take your case. If your case is quite hard to win, it can be difficult to find a lawyer. (Though we recommend trying our service before you give up!) In this case, you can apply on your own, and then try again to find a lawyer once you’ve been denied once, at which point it’s often easier to get representation.

There are no upfront costs if you work with a disability lawyer. If they win your case, they get 25% of any back pay they win for you. This is worth it for almost everyone — you only pay if you win (if you lose, you pay nothing). You only pay once, and the cost pales in comparison to the amount you get.
