Answer:
The accounts belong to the beneficiary whether or not he or she is ready to close them. Interest earned through the date of death should be reported under the deceased owner's SSN. From the date of death forward, it should be reported under the SSN of the new owner. If the beneficiary wants the account to roll over, rather than withdraw the funds, I assume you'd accommodate him or her.
