SSDI and SSI
Social Security has two programs that provide cash benefits to people with disabilities or who are blind:
Social Security Disability Insurance
SSDI provides benefits to disabled or blind individuals who are “insured” by workers’ contributions to the Social Security trust fund. These contributions are based on your earnings (or those of your spouse or parents) as required by the Federal Insurance Contributions Act (FICA).

Supplemental Security Income Program
The SSI program makes cash assistance to aged, blind, and disabled individuals (including children under age 18) who have limited income and resources. The Federal Government funds SSI from federal tax revenues. In addition, Massachusetts provides a supplement to the monthly Federal amount and rolls it into one monthly check.
