SSI vs SSDI: What's the Difference and How to Apply
Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) both support people with disabilities but work differently. This guide explains who qualifies, how much you may receive, how to apply, and how the programs interact with Medicaid and Medicare.
Key Points
- SSI is needs-based; SSDI is insurance-based (work credits).
- SSI often links to Medicaid; SSDI is tied to Medicare after a waiting period.
- You can qualify for both (concurrent benefits).
- Report life changes promptly to avoid overpayments.
SSI at a Glance
- What it is: A means-tested cash benefit for people with limited income/resources.
- Eligibility basics: disability standard + financial limits.
- Healthcare linkage: In many states, SSI → Medicaid eligibility (state rules vary).
- Payment amount: Federal base rate plus possible state supplements.
SSDI at a Glance
- What it is: Insurance benefit based on your work history and payroll contributions.
- Eligibility basics: meet disability definition + sufficient work credits.
- Healthcare linkage: Medicare eligibility after qualifying waiting period.
- Payment amount: Based on average lifetime covered earnings.
