Social Security Disability Insurance (SSDI) provides monthly income to individuals who can no longer work due to a qualifying disability. Unlike SSI, SSDI is based on your work history and the Social Security taxes you have paid — not on financial need.
35 steps across 8 sections
1. Verify Work Credit Eligibility
- You need 40 work credits total, with 20 earned in the last 10 years (for age 31+)
- Younger workers need fewer credits (as few as 6 credits for age 24 or under)
- Check your credits at ssa.gov/myaccount
- One credit = $1,810 in earnings (2026); max 4 credits/year
2. Confirm Your Condition Qualifies
- The disability must prevent you from performing "substantial gainful activity" (SGA)
- SGA threshold: $1,620/month in earnings for 2026 (non-blind); $2,700 for blind individuals
- The condition must last or be expected to last at least 12 months or result in death
- Review SSA's Listing of Impairments (Blue Book) for qualifying conditions
3. Gather Medical Documentation
- Names, addresses, phone numbers, and patient ID numbers for all doctors and hospitals
- Dates of all medical treatments and hospitalizations
- Names of all medications and who prescribed them
- Names and dates of all medical tests (MRIs, X-rays, lab work)
- Medical records, treatment notes, and any disability-related reports
4. Collect Additional Required Documents
- Social Security number and birth certificate
- Names, dates of birth, and SSNs of your spouse and minor children
- Workers' compensation or other disability benefit information
- Employment history for the last 15 years (job titles, duties, dates)
- Most recent W-2 or tax return
5. Submit the Application
- Online Apply at ssa.gov/applyfordisability (most convenient)
- Phone Call 1-800-772-1213 (Mon-Fri, 7am-7pm)
- In person Visit your local Social Security office (schedule appointment)
- The application takes 1-2 hours to complete
6. Cooperate with Disability Determination
- Your state's Disability Determination Services (DDS) reviews your medical evidence
- You may be required to attend a consultative examination (CE) with an SSA-approved doctor
- Respond promptly to all requests for additional information
- Processing typically takes 3-6 months for initial decision
7. Understand the Waiting Period
- SSDI benefits begin after a 5-month waiting period
- The waiting period starts from your "established onset date" (when disability began)
- If approved retroactively, you may receive back pay for months after the waiting period
- Medicare eligibility begins 24 months after SSDI eligibility
8. Appeal if Denied
- Reconsideration First level of appeal (60 days to file)
- ALJ Hearing Hearing before an Administrative Law Judge (highest approval rate ~50%)
- Appeals Council Review of ALJ decision
- Federal Court Final appeal option
- Consider hiring a disability attorney (they work on contingency, capped at 25% of back pay or $7,200)
Common Mistakes

- Not listing all medical conditions
