Why does Turbotax allow a 19 year old who is not a full-time student be claimed as a dependent on a parent's return?

[Hal_Al · Accepted solution]

There are two types of dependents, "Qualifying Children"(QC) and standard ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit, a relationship test and residence test. Only a QC qualifies a taxpayer for the Earned Income Credit and the Child Tax Credit. They are interrelated but the rules are different for each.

A 19 year old can still be a qualifying relative if his income is under $4050.

Otherwise, you've answered something wrong in the interview.
