Social Security Disability Insurance (SSD or SSDI) is a payroll tax-funded, federal insurance program of the United States government. It is managed by the Social Security Administration and is designed to provide income supplements to people who are physically restricted in their ability to be employed because of a notable disability, usually a physical disability.
According to the Social Security Administration (SSA), a person qualifies for SSDI if they:
have a physical or mental condition that prevents them from engaging in any "substantial gainful activity" ("SGA"), and
the condition is expected to last at least 12 months or result in death, and
they are under the age of 65, and
generally, have worked 5 out of the last 10 years[1] as of the determined date of onset of disability
The work requirement is waived for applicants who can prove that they became disabled at or before the age of 22, as these individuals may be allowed to collect on their parent's or parents' work credits.
