SSI & SSDI
What Is the Difference Between SSI and SSDI?
By Ronnie Shaw, Social Security Disability Advocate · September 27, 2026
SSI (Supplemental Security Income) is a needs-based program with income and resource limits. SSDI (Social Security Disability Insurance) is based on your work history and Social Security credits. Both can involve disability standards, but the money rules and payment sources differ.
What this usually means
- SSDI looks at work credits; SSI looks at financial need
- Medicare and Medicaid connections often differ by program
- Some people receive one; some receive both
What to do next
- Check which program your notices name
- Do not mix SSI reporting rules with SSDI work rules
- Keep medical and financial documents organized separately when needed
- Ask before assuming advice for one program applies to the other
