How to apply for Supplemental Security Income (SSI)

Social Security Administration

Who it's for

SSI is a federal monthly cash benefit for people 65 and older (or blind / disabled at any age) with very limited income and resources. It's a separate program from Social Security retirement — you can qualify for SSI even if you never worked enough to get Social Security, and many people qualify for both. In California, SSI recipients also get the State Supplementary Payment (SSP) on top, which adds several thousand dollars a year to the federal benefit. SSI is also a gateway: it can automatically open the door to Medi-Cal, CalFresh, and Extra Help.

What you'll need

  • Social Security card
  • Birth certificate or proof of age
  • Proof of U.S. residency
  • Bank statements for the last 3 months
  • Proof of all income (Social Security, pensions, wages)
  • Information about any property you own
