Unlike SSI, SSDI is an earned insurance benefit. To qualify, you must have accumulated enough work credits by paying Social Security taxes. In 2026, you earn one credit for every $1,730 in covered earnings, with a maximum of four credits per year.

How Many Credits Do You Need?

The number of credits required depends on your age when you became disabled. Workers who become disabled before age 24 may qualify with as few as 6 credits earned in the 3 years before disability. Workers aged 24โ€“31 need credits for half the time between age 21 and the onset of disability. Workers aged 31 and older generally need 40 credits total, with 20 earned in the 10 years immediately before disability.

The "Recent Work" Requirement

Beyond total credits, most workers must also meet a "recent work" test โ€” demonstrating that they worked recently enough to still be "insured" under SSDI. If you stopped working years ago and have been out of the workforce, you may have lost your SSDI insured status even if you previously had enough credits. This is called your Date Last Insured (DLI), and applying before your DLI expires is critical.

Checking Your Credits

The easiest way to check your work credits and insured status is to create a my Social Security account at ssa.gov. Your Social Security Statement shows your earnings history year by year and estimates your benefit amount if you became disabled today. This is the single most valuable document for planning your disability claim.

What If You Don't Have Enough Credits?

If you don't meet the SSDI work credit requirement, you may still qualify for Supplemental Security Income (SSI), which is need-based rather than earnings-based. SSI has no work history requirement but imposes strict income and resource limits ($2,000 for individuals). See our SSDI vs SSI guide for a full comparison of the two programs.
