Supplemental Security Income is a federally administered disability program authorized under Title XVI of the Social Security Act. Supplemental Security Income gives monthly cash assistance to claimants who are determined aged, blind or disabled and have limited income and resources. Children may also be eligible for SSI payments. The Supplemental Security Income program is funded through general tax revenues. A set benefit payment amount has been authorized by the federal government for all Social Security Disability claimants, but many states provide an additional benefit amount. State supplements may be added to the federal rate for one monthly payment to the claimant or paid separately.
