Social Security Disability FAQs

How many work credits do I need to qualify for SSDI?

Quick Answer

Most adults under 62 need 40 work credits — 20 of which must be earned in the 10 years before disability onset. In 2026, one credit equals $1,810 in covered earnings; you can earn up to 4 credits per year. Younger workers need fewer credits under a sliding scale in 42 U.S.C. §423(c).

What you need to know

Work credits are the currency of SSDI eligibility. Every year you work and pay Social Security taxes, you earn up to 4 credits. In 2026 you earn one credit for every $1,810 in wages or self-employment income, so $7,240 in annual earnings maxes out your credits for the year.

The number of credits you need depends on your age when you become disabled:

Age 31 or older: You generally need 40 total credits, with 20 earned in the 10 years immediately before your disability began. This is the ’20/40 rule.’
Age 24–30: You need credits for half the time between age 21 and the onset of your disability.
Under age 24: You only need 6 credits earned in the 3-year period before your disability.

Your work credit history is tracked on your Social Security earnings record. You can check it at ssa.gov or request a copy from our office. If you did not earn enough credits, you may still qualify for SSI, which has no work requirement.

Under 42 U.S.C. §423(c), SSA also looks at your ‘date last insured’ (DLI). If you stopped working years ago, your insured status may have expired. Acting quickly matters. Call us today — no fee unless we win, with a federal fee cap of 25% of back-pay up to $7,200.
