Supplemental Security Income

Overview

Supplemental Security Income (SSI) is a federal means-tested cash assistance program administered by the Social Security Administration that provides monthly income support to aged (65+), blind, or disabled individuals with limited income and financial resources. Unlike Social Security Disability Insurance (SSDI), SSI requires no work history — eligibility is based entirely on categorical status (age, blindness, or disability) and financial need (income and asset tests). The federal benefit rate was approximately $698/month for an individual in 2012. SSI receipt categorically confers Medicaid eligibility in most states. The program serves two distinct populations: disabled adults without sufficient work history for SSDI, and children with disabling conditions from low-income families.

Key Contributions / Features

• No work history requirement: Workers who have never paid Social Security payroll taxes (or too little for insured status) qualify if they meet the disability and financial tests; this distinguishes SSI from SSDI's insurance structure
• Asset means-test: Federal limit of $2,000 for individuals ($3,000 for couples); excludes applicants with meaningful savings, rendering SSI inaccessible to workers with moderate assets even if severely impaired
• Categorical Medicaid link: SSI receipt automatically triggers Medicaid enrollment in most states, making health insurance a major benefit beyond cash — critical for beneficiaries with ongoing medical needs
• Children's SSI: Children under 18 with severe disabilities whose families meet income/asset tests qualify; the age-18 redetermination (applying adult eligibility criteria) is a major policy trigger. See SSI Children's Program
• SSDI-SSI concurrence: Workers with qualifying disabilities but insufficient earnings history may receive concurrent SSDI and SSI; SSI fills the gap between the SSDI benefit and the federal benefit rate
• Section 1619(b): Allows SSI beneficiaries to retain Medicaid eligibility even when earnings exceed the Substantial Gainful Activity threshold — a work incentive designed to avoid the "Medicaid cliff" that would otherwise trap beneficiaries in non-employment
