Do you qualify for Social Security disability benefits?

You generally qualify for Social Security disability if a medical condition keeps you from doing substantial work and has lasted, or is expected to last, at least 12 months or to result in death. For SSDI you also need enough recent work credits. For SSI you need limited income and resources instead.

The short answer

The Social Security Administration (SSA) pays only for total disability. There are no benefits for partial or short-term disability. To be found disabled as an adult, SSA generally has to agree on three things:

• You can’t do substantial work. In 2026, SSA treats earnings over $1,690 a month as substantial gainful activity, or $2,830 a month if you are blind.
• Your condition is medically documented and severe. A statement about your symptoms is not enough on its own. SSA needs medical evidence such as exam findings, test results and treatment records.
• It lasts. The condition has lasted, or is expected to last, at least 12 straight months, or is expected to result in death.

Then there is the program question. SSDI is for people who worked and paid Social Security taxes long enough. SSI is for people with little income and few resources, whether or not they have worked. Many people apply for both at once.

The medical requirement

SSA calls it a “medically determinable impairment.” It has to come from physical or mental abnormalities that acceptable medical sources can show with clinical findings or tests. A diagnosis helps, but SSA cares more about what the condition stops you from doing.

SSA keeps a list of conditions, often called the Blue Book, that are severe enough on their own to qualify when the medical criteria are met. The adult list covers 14 body systems, from musculoskeletal and heart conditions to mental disorders, cancer and immune system disorders. You can see how these groups work on our disability conditions page.

You do not have to meet a listing to be approved. If you don’t, SSA decides your residual functional capacity, which its rules define as “the most you can still do despite your limitations.” That covers things like how long you can sit, stand and walk, how much you can lift, how well you can concentrate, and whether you will miss work or need extra breaks. Detailed records from the providers who treat you are usually the most useful evidence here.

SSA also looks at all of your conditions together. Its rules say it considers the combined effect of every impairment, even ones that would not be severe enough by themselves.

The work and duration requirements

Work credits (SSDI only). You earn credits by working and paying Social Security taxes. In 2026, you earn one credit for each $1,890 in wages or self-employment income, up to four credits a year. SSA generally uses two tests:

• Recent work. If you are 31 or older, you generally need 20 credits earned in the 10 years before your disability began.
• Duration of work. Most workers need about 40 credits in total. Younger workers can qualify with fewer. Before age 24, six credits in the three years before disability can be enough.

Because of the recent-work test, SSDI coverage generally lapses some years after you stop working. If you stopped working long ago, SSA will ask whether you became disabled before your coverage ran out. That question comes up in many SSDI claims.

Duration (both programs). The 12-month rule applies to SSDI and SSI alike. A serious injury that is expected to heal within a year usually will not qualify, even if you can’t work right now.

Income and resources (SSI only). SSI has no work-credit test. Instead, your countable resources must be $2,000 or less ($3,000 for a couple), and your countable income must be low. Your home and one vehicle used for transportation generally don’t count.

The five-step evaluation the SSA uses

SSA decides every adult claim with the same five questions, in order. A claim can stop at any step.

1. Are you working? If you are earning above the substantial gainful activity level, SSA generally finds you are not disabled.
2. Is your condition severe? It must significantly limit basic work activities and meet the 12-month duration rule.
3. Does it meet or equal a listing? If it does, you are found disabled. If not, SSA moves on.
4. Can you do your past work? SSA looks at the jobs you held in recent years. If your residual functional capacity still allows that work, the claim is denied.
5. Can you do any other work? SSA considers your limitations along with your age, education and work experience. If you can’t adjust to other work, you are found disabled.

Steps 4 and 5 often decide a claim. They turn on details: what your old jobs really required, and exactly what your doctors say you can and can’t do.

How age affects a disability decision

Age matters at step 5. SSA’s rules treat it this way:

• Under 50. SSA generally does not consider age to seriously affect your ability to adjust to other work.
• 50 to 54. Age, along with a severe impairment and limited work experience, may seriously affect your ability to adjust to other work.
• 55 and older. SSA’s rules say age “significantly affects” a person’s ability to adjust to other work.
• 60 and older. Special rules apply for people closely approaching retirement age.

So a 56-year-old and a 40-year-old with the same limitations can get different decisions. Not sure where you stand? Our free case review is a quick way to find out.

What to do if you were already denied

Many people are denied at first, and a denial is not the end of a claim. You have 60 days to appeal each decision. SSA assumes you received the notice five days after the date printed on it, unless you can show otherwise.

The appeal steps are:

1. Reconsideration. A new reviewer looks at the claim.
2. Hearing. An administrative law judge hears your case, usually by online video or phone.
3. Appeals Council review.
4. Federal court.

The hearing is often the best chance to explain your limitations in your own words and fill gaps in the medical record. If you have a denial letter in hand, read our guide to denied disability claims and how the appeals process works. If you miss the deadline, SSA can allow more time only if you show good cause. Otherwise you generally have to start over with a new application.

Common questions

Can I work part time and still qualify?

Sometimes. If your earnings stay under SSA’s substantial gainful activity level ($1,690 a month in 2026, or $2,830 if you are blind), work alone does not end a claim. SSA may still look at what the work shows about your abilities.

What if I don’t have enough work credits for SSDI?

You may still qualify for SSI if your income and resources are low enough. You may also qualify on a parent’s or spouse’s record as a disabled adult child or a disabled widow or widower.
