Q. What is the main advantage of a typical 529 plan?
A. Earnings are not subject to federal tax and generally not subject to state tax when used for the qualified education expenses of the designated beneficiary, such as tuition, fees, books, as well as room and board at an eligible education institution and tuition at elementary or secondary schools. Contributions to a 529 plan, however, are not deductible.
