SSI and SSDI Compared
The Social Security Administration (SSA) has 2 different pathways for those who are eligible for disability benefits. These are the Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) schemes that have some similar and some different requirements in order to qualify.
The major difference between the two disability benefits is that SSI eligibility is based on age/disability and the amount of income and assets the claimant has, while eligibility for SSDI is determined by extent of the disability and accumulated work credits.
