Yes, kiddie tax makes it infeasible for most to withdraw until they are supporting themselves. This can be the year they graduate if they have a job for the rest of the year. But if they don’t earn more than half of their expenses then you may have to wait to the year after graduation (and are not a full time student in 5 months of the year) or the year they turn 24 (whichever is earlier). The exception is a kid with a near full ride scholarship (so minimal parental support) who gets a well paid summer job during college (and doesn’t live at home where you have to calculate imputed rent as parental support).
