SSDI work credits — the recent-work test and the duration test

SSA measures covered work in credits, also called quarters of coverage. In 2026 you earn one credit for each $1,890 of earnings in covered work, and you can earn at most 4 credits in a year — so $7,560 of covered earnings in 2026 earns all 4 credits. (In 2025 the figure was $1,810 per credit.) You do not need to earn credits in separate calendar quarters any more, despite the old name: it is the annual total that counts.

There are two work tests, and younger workers face easier versions of both. The recent work test asks whether you worked recently enough. The duration of work test asks whether you worked long enough in total.

The recent work test

Age when disability began	Rule
Before age 24	6 credits in the 3 years before onset.
Ages 24 to 30	Credit for half the time between age 21 and onset. Example: disabled at 27, half of the 6 years from 21 to 27 is 3 years of work, or 12 credits.
Age 31 and older	Generally 20 credits in the 10 years immediately before onset.
Statutory blindness	No recent work test — only the duration test applies.

Read the table with care. The age-24-to-30 rule is the one people most often misread: it is half the time between 21 and your onset age, not half of your total working life. If your birthday falls near a boundary, confirm your exact requirement on SSA's Benefits Planner credits page or in your my Social Security statement.

The duration of work test (estimated years of work needed)

Age when disability began	Years of work (estimate)
Before 28	1.5
30	2
34	3
38	4
42	5
46	6
50	7
54	8
58	9
60	9.5
62 and older	40 credits maximum (10 years of work)

These are SSA's published estimates. The exact credit count for your age is on the same SSA credits page, and your own record may differ if some of your work was not covered (for example, some state and local government jobs, or work abroad).

How to check your own record

Open a my Social Security account at ssa.gov and read your Social Security Statement. It shows your earnings year by year and your estimated disability benefit. If earnings are missing — a common problem with old jobs or name changes — gather pay stubs, W-2 forms, or tax returns before you apply, because correcting an earnings record during a claim slows it down.
