529 Distribution allocation
My son moved from one state to another midyear. The contributions into his 529 plan were all made in the former state, but he received distribution in the new state. Filling out his Part Year resident forms for the former state, it asks what amount of the earnings was earned while a resident of it. One thought is all the money was contributed while living in his home state; another thought is all the actual earnings were obtained when he received the distribution while living in the new state. What is the proper state to declare the earnings in?
