SSDI application

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)

  • 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)
