Getting Social Security Disability Insurance (SSDI) is not easy. The Social Security Administration (SSA) rejects most initial applications, and many of them fail because the applicant does not meet one of the basic requirements of the program.
Unlike SSI, SSDI is an insurance: it is paid to workers who have contributed to Social Security through their payroll taxes. That is why the first requirement has nothing to do with health, but with work history.
Work requirements
- Total credits | generally 40 credits, 20 of them earned in the 10 years before the disability began.
- Younger workers | need fewer credits. A worker under 24 can qualify with 6 credits earned in the three years before the disability.
- Value of a credit | $1,890 in earnings in 2026 and $1,970 in 2027.
The “recent work” test is the one that surprises many applicants. A person who stopped working more than five years before becoming disabled may have lost their insured status, even if they worked for decades.
Medical requirements
The SSA uses a strict definition of disability. The applicant must have a medical condition that prevents substantial work and that has lasted, or is expected to last, at least 12 months or result in death. Partial or short-term disability is not covered.
Work is considered substantial when it exceeds the SGA limit: $1,690 a month in 2026, which will rise to $1,770 in 2027. Some serious illnesses are processed faster through the Compassionate Allowances program, which recently added 14 new conditions.
The five-month wait
Even after approval, SSDI does not pay for the first five full months of disability. And Medicare only begins after 24 months of entitlement to benefits. We explained both waits in our article about the SSDI waiting periods.
How much SSDI pays
The average SSDI check is $1,642 a month and will rise to $1,701 in January with the 3.6% COLA. Payments are made on Wednesdays depending on the beneficiary’s birthday. In October, the remaining dates are October 21 and October 28.
