What SSI is
Supplemental Security Income (SSI) is a federal Social Security program that may provide monthly payments to people with disabilities who meet the applicable disability, income and resource requirements.
SSI is administered by the Social Security Administration (SSA), not by DDD and not by Vicabell.
Why age 18 matters
When someone turns 18, Social Security generally evaluates disability eligibility using the adult disability rules. Parental income and resources are generally no longer counted the same way they are for a child living with parents.
This means a young adult's outcome at 18 can be different from an earlier childhood decision. Payment amounts and individual outcomes vary, so no amount is listed here.
When should we start learning about SSI?
Many families begin reading about SSI in the year before the individual turns 18, so there is time to gather records and understand the process. Contact SSA for current timing, requirements and how to apply.
