Social Security Disability Application
Updated October 2026 · 2026 figures from the Social Security Administration and IRS
You can file a Social Security disability application online at ssa.gov, by phone at 1-800-772-1213 or at a local office. SSA needs your work history and full medical details (Form SSA-3368) plus permission to get your records. An initial decision took 188 days on average in August 2026 (SSA performance data, August 2026); denials can be appealed within 60 days.
Retirement Rules Guide is an independent site, not the Social Security Administration. We can't process applications or see your record; every official action below happens at ssa.gov, by phone with SSA or at an SSA office.
This guide covers Social Security Disability Insurance (SSDI), which pays workers who have paid into Social Security. Supplemental Security Income (SSI) is a separate need-based program; you can apply for both in the same interview.
Do you qualify for SSDI?
You need two things: enough recent work and a disability that meets SSA's strict definition.
Work credits
| Age when disabled | Credits generally needed |
|---|---|
| Before 24 | 6 credits in the 3 years before you became disabled |
| 24 to 30 | Credits for half the time between 21 and your disability |
| 31 or older | At least 20 credits in the 10 years before you became disabled (more in total as you get older, up to 40) |
In 2026 you earn one credit for each $1,890 of earnings, up to four a year (SSA 2026 COLA fact sheet). Stopped working more than five years ago? You may no longer be insured for SSDI — check your Social Security Statement, which shows whether you qualify today.
Medical rules
- You can't do substantial gainful activity — in 2026, earning more than $1,690 a month ($2,830 if blind).
- Your condition must be expected to last at least 12 months or result in death. There's no partial or short-term SSDI.
- You can't do your past work or, considering your age, education and experience, adjust to other work. Rules are more lenient from age 50.
How to apply for SSDI, step by step
- Check you qualify. You need enough work credits and a condition that stops you from doing substantial work (over $1,690 a month in 2026) and is expected to last at least 12 months or result in death.
- Collect medical and work details. Doctors, hospitals and clinics with addresses and dates, medications, tests, and the jobs you held in the last five years.
- Apply. Online at ssa.gov/disability, by phone at 1-800-772-1213, or at a Social Security office by appointment.
- Complete the Adult Disability Report. Form SSA-3368 asks about your conditions, treatment and work history. Sign Form SSA-827 so SSA can get your medical records.
- Answer every request quickly. The state Disability Determination Services may ask for forms or a free consultative exam; missing them can lead to denial.
- Appeal if denied. You have 60 days (plus 5 for mail) from the date on the denial letter to ask for reconsideration.
What to include in your Social Security disability application
Most denials come from thin medical evidence, not from the condition itself. Before you file, collect:
- Every doctor, hospital, clinic and therapist you've seen for the condition, with dates, phone numbers and patient ID numbers.
- Test results (MRI, X-rays, blood work, mental health evaluations) and a full medication list with doses and side effects.
- Your jobs in the last five years: titles, dates, duties, and how much you lifted, stood or sat.
- A doctor's statement of your specific limits (how long you can sit, stand, lift, concentrate) — this often carries more weight than a diagnosis.
- Workers' compensation or other disability payments you receive.
How long the process takes
A Social Security disability application can go through up to four levels:
| Stage | Typical time |
|---|---|
| Initial decision | 188 days on average (August 2026) |
| Reconsideration | Several months; request within 60 days of denial |
| Hearing before an administrative law judge | 276 days on average to a decision (August 2026) |
| Appeals Council, then federal court | Often a year or more each |

When payments start and what you get
- Five-month waiting period: benefits start with the sixth full month after SSA says your disability began (no wait for ALS).
- Back pay: you can be paid for up to 12 months before the application date, after the waiting period, so apply as soon as you stop working.
- Amount: based on your earnings record, like a retirement benefit at full retirement age. All disabled workers averaged $1,630 a month in January 2026 (SSA 2026 COLA fact sheet).
- Medicare: starts after 24 months of SSDI payments (sooner for ALS and kidney failure) — see Medicare eligibility.
- At full retirement age SSDI converts to retirement benefits at the same amount.
Do you need a lawyer?
Not to apply, but many people hire a representative for appeals and hearings. Fees are regulated: in most cases 25% of past-due benefits, capped at $9,200, and paid only if you win. Free help is also available from legal aid offices.
Frequently asked questions
How do I apply for Social Security disability?
Apply online at ssa.gov/disability, call 1-800-772-1213 or make an appointment at a Social Security office. You'll complete the Adult Disability Report (SSA-3368) and sign Form SSA-827 to release your medical records.
How long does a Social Security disability application take?
Initial decisions took 188 days on average in August 2026. If you're denied and appeal to a hearing, add roughly another 9 months or more.
Can I work while applying for disability?
You can earn a little, but earning more than $1,690 a month in 2026 ($2,830 if blind) generally means SSA will find you're not disabled.
What is the most common reason SSDI is denied?
Insufficient medical evidence, earning above the substantial gainful activity limit, not having enough work credits, or missing a consultative exam or form.
How much back pay will I get from SSDI?
Up to 12 months before your application date, counted after the five-month waiting period, plus all months while your claim was pending.
