SSDI Eligibility: Who May Qualify?
SSDI eligibility is based on two broad questions: whether Social Security considers your condition disabling under its rules, and whether your work history is sufficient for insured status. A diagnosis alone does not establish eligibility.
Last reviewed: July 13, 2026
The basic SSDI eligibility test
To qualify for Social Security Disability Insurance, you generally need a medically determinable physical or mental condition that prevents substantial work, is expected to last at least 12 continuous months or result in death, and enough recent work covered by Social Security. Social Security evaluates both medical and non-medical requirements.
How work history affects eligibility
Workers earn Social Security credits through covered earnings. The number of credits needed depends partly on age when disability begins. Many adults need 40 credits, including 20 earned during the 10 years ending with the year disability began, but younger workers may qualify with fewer credits.
The 2026 earnings limit
For 2026, Social Security lists substantial gainful activity at $1,690 per month for most non-blind applicants and $2,830 per month for statutorily blind applicants. Self-employment is evaluated under additional rules, so revenue alone may not determine the result.
Medical evidence matters
Social Security looks for objective medical evidence from acceptable medical sources. Records should show diagnoses, treatment, testing, symptoms, response to treatment, and—most importantly—how the condition limits work-related activities.
What eligibility does not mean
Meeting a medical listing is one route to approval, but it is not the only route. Social Security may also consider whether your condition medically equals a listing or whether your remaining functional capacity prevents past work and other work.

Check EligibilityFrequently asked questions
Can I qualify for SSDI while working?
Possibly. Earnings and the nature of the work matter. For 2026, earnings above the applicable SGA level may indicate that a person is performing substantial gainful activity, but special rules and deductions can apply.
Do assets affect SSDI eligibility?
SSDI is an insurance program based on work history, not a needs-based program. Asset limits generally apply to SSI rather than SSDI.
Does a diagnosis automatically qualify me?
No. Social Security evaluates severity, duration, evidence, and functional limitations—not the diagnosis alone.
