Who Qualifies for Social Security Disability?

Social Security's definition of disability

For adults, Social Security considers you disabled if a medical condition keeps you from doing substantial work, and it's expected to last at least 12 months or result in death. There's no benefit for short-term or partial disability.

The earnings limit (substantial gainful activity)

If you're working and earning more than a set amount, Social Security generally won't find you disabled. That amount is called substantial gainful activity (SGA). In 2027 it's $1,770 a month, or $2,950 a month if you're blind. (In 2026 it was $1,690 and $2,830.)

Work credits (SSDI only)

You earn work credits by working and paying Social Security taxes. In 2027, you earn one credit for each $1,970 in earnings, up to four credits a year.

Most people need 40 credits, 20 of them earned in the 10 years before becoming disabled. Younger workers can qualify with fewer credits. SSI doesn't require work credits.

The 5 questions Social Security asks

Social Security reviews every disability claim with the same five questions, in order:

• Are you working above the earnings limit? If yes, you generally won't qualify.
• Is your condition severe enough to limit basic work activities?
• Is your condition on Social Security's list of impairments (the 'Blue Book'), or as severe as one that is?
• Can you still do the kind of work you did before?
• If not, can you do any other kind of work, considering your age, education, and skills?

That last question is why age matters. It's often easier for people 50 and older to qualify, because Social Security considers how hard it is to switch to a new kind of work.
