Supplemental Security Income (SSI) is one of the most important supports for people with disabilities — and one of the most misunderstood. Here's a plain-language overview of how it works and where families most often get stuck.
What SSI is
SSI is a monthly, needs-based benefit for people who are disabled or blind and have limited income and resources. It's run by Social Security, but it is not the same as the retirement benefits people pay into — it's based on need.
Child rules vs adult rules
For a child, a portion of the parents' income and resources is counted toward eligibility. At 18, that changes — the young adult is evaluated on the adult standard, and a child who didn't qualify before sometimes qualifies now. This re-determination is a key moment.
The income and resource limits
SSI has strict limits on income and countable resources. This is exactly why the savings tools in the next article (ABLE accounts and special-needs trusts) matter so much — they let a person hold money without blowing past the limit.
