Learn the Difference Between Social Security Disability Insurance and Supplemental Security Income

Two very important public benefit programs are available that people often confuse for one another. Here’s a primer on the features of and differences between Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI).

Social Security Disability Insurance (SSDI)

The program is financed with Social Security taxes paid by workers, employers, and self employed persons.

  • The worker will get Medicare coverage automatically after receiving disability benefits for two years.
  • To be eligible for a Social Security benefit, the worker must earn sufficient credits based on taxable work to be “insured” for Social Security purposes.
  • Disability benefits are payable to:
    • blind or disabled workers
    • their children
    • widow(er)s
    • adults disabled since childhood
  • The amount of the monthly disability benefit is based on the Social Security earnings record of the insured worker.

See Understanding the Benefits for a complete explanation SSDI.

Supplemental Security Income (SSI)

This program is financed through general revenues from taxes, meaning benefits are not based on your prior work history.

  • In most states, beneficiaries will automatically be eligible for Medicaid.
  • SSI benefits are payable to:
    • individuals age 65 or older
    • adults who are disabled or blind
    • children who are disabled or blind
  • Eligibility requirements:
    • have limited income and resources
    • meet the living arrangement requirements
    • a U.S. citizen or national, or in one of certain categories of aliens
  • The monthly payment varies up to the maximum federal benefit rate, which may be supplemented by the state.
