Q. What is the difference between Social Security and SSI?

A. Both Social Security Disability (SSD) and Supplemental Security Income (SSI) are programs of the Social Security Administration. Both SSD and SSI require the same basic requirement for coverage- an inability to work at any job for a period of twelve (12) months or more. SSD benefits are based on the taxes you have paid into the system before you became disabled. SSI benefits are based on financial need.
