529 Plans and Qualified Charitable Distributions: Today’s Slott Report Mailbag

QUESTION:

I have been funding a 529 account for over 15 years and no longer need to add deposits.

Could I change the beneficiary to myself and then convert to a Roth IRA, assuming I have met the 5-year deposit hurdle as well? Has the government ruled on when the clock starts for the 15 years? Meaning, is it from when you open the account or does it restart when you change the beneficiary?
