If you’ve saved for your child’s education using 529 plans but you don’t end up spending all the money in the account, what are the available options? First, you can leave the money in the account. Unlike Coverdell accounts, there is no requirement to liquidate the account by a certain age. Money can stay in the account and could eventually be used for graduate school — even if that is 10 or 15 years later. In fact, the money can remain in the plan indefinitely as long as there is a living beneficiary.
