What is Age 18 Redetermination?
When a young person receiving Supplemental Security Income (SSI) turns 18, the Social Security Administration (SSA) reviews their case to determine whether they still qualify—this time using adult disability rules.
These adult rules are different and place more emphasis on whether the person can work and earn above Substantial Gainful Activity (SGA). Because of this shift, some young people may lose their SSI benefits at age 18, even if they qualified as a child.
Understanding this process early can help families prepare, gather documentation, and explore supports to maintain stability during the transition to adulthood.
