Q. I get SSI. I am eligible for a Disabled Adult Child’s benefit on my dad’s Social Security retirement check since I was disabled before the age of 22. Will the dependent child benefit affect my SSI?

A. Supplementary Security Income (SSI) is an assistance benefit based on need. Its purpose is to “supplement” any other income the applicant may have.

If you become eligible for a Disabled Adult Child Social Security benefit when your father retires, your SSI must be re-determined. SSI allows a disregard of $65 of earned income plus $20 of income from any source. All other income counts in determining whether any SSI is payable.
