|Can more than one account be opened for the same child?|
Yes. You (or anyone else) can open multiple 529 accounts for the same beneficiary, as long as you do so under different 529 plans (college savings plan or prepaid tuition plan). For instance, you could open college savings plan accounts with State A and State B for the same beneficiary, or you could open a college savings plan account and a prepaid tuition plan account with State A for the same beneficiary. But you can't open two college savings plan accounts in State A for the same beneficiary.
Also, keep in mind that if you do open multiple 529 accounts for the same beneficiary, each plan has a limit, and contributions can't be made after the limit is reached. Some states consider the accounts in other states to determine if the limit has been reached. For these states, the total balance of all plans (in all states) cannot exceed the current year's maximum contribution amount.
