Children under 18 can receive Supplemental Security Income (SSI) benefits only. The standards for winning a child’s benefits are much harder than winning an adult case. Children can also receive benefits if an eligible parent is disabled, retired or deceased. They can receive benefits until they graduate high school or until age 18, whichever is later. The amount they receive though depends on how much the adult receives. Certain adults who never earned very much money may find that the children do not receive benefits.
