What Happens to Unused 529 Money?
Nothing happens automatically: a 529 balance simply keeps growing tax-deferred until the account owner acts, and federal law now provides at least seven exit paths that preserve some or all of the tax benefit. Ranked by tax treatment, the options run from fully tax-free moves, such as changing the beneficiary, rolling up to $35,000 into the beneficiary's Roth IRA, or spending on newly qualified credentialing expenses, down to a nonqualified withdrawal, which triggers income tax plus an additional 10 percent tax on the earnings portion, under the rules in IRS Topic No. 313. There is no deadline forcing a decision, accounts can stay open indefinitely, and the options can be combined, with part of a balance rolled to a Roth IRA while the rest waits for graduate school or a new beneficiary.
Which Options Keep the Money Fully Tax-Free?
Four paths preserve the complete tax benefit:
- Change the beneficiary. The owner can name another member of the beneficiary's family, including siblings, parents, first cousins, nieces and nephews, and the owner themselves, with no tax consequence, as described in IRS Publication 970.
- Hold the account. Funds waiting for graduate school, a career change, or a future grandchild continue compounding tax-deferred with no time limit.
- Spend on expanded qualified expenses. Legislation enacted in 2025 added postsecondary credentialing costs, including trade licenses, CPA and bar exam fees, and continuing education, for distributions after July 4, 2025, and raised the K-12 withdrawal cap to $20,000 per year beginning in tax year 2026, per Saving for College.
- Use apprenticeship and loan provisions. Registered apprenticeship costs qualify, and limited amounts can repay the beneficiary's qualified education loans, subject to a lifetime cap per borrower.
How Does the Roth IRA Rollover Work?
Under rules that took effect in 2024, unused 529 funds can move to a Roth IRA owned by the account beneficiary, up to a lifetime limit of $35,000. Conditions apply: the 529 account must have been open at least 15 years, annual rollover amounts count against the year's IRA contribution limit, and contributions made within the previous five years are excluded from rollover. The transfer converts education savings into retirement savings without income tax or penalty, which removed much of the historical worry about overfunding an account. For a beneficiary who finished school with money left over, the rollover ranks high on the list because it keeps every dollar in a tax-advantaged wrapper.
What About Beneficiaries With Disabilities?
A 529 balance can roll into an ABLE account for the same beneficiary or a family member with a disability, and 2025 legislation made this rollover authority permanent for tax years after December 31, 2025. ABLE accounts hold savings for disability-related expenses without jeopardizing means-tested benefits, within program limits. The rollover counts against the ABLE account's annual contribution limit, and the receiving beneficiary must meet ABLE eligibility rules tied to the onset of disability. For families whose education plans changed because of a disability, the permanent rollover provides a tax-free redirection of the funds toward housing, transportation, assistive technology, and other qualified disability expenses.
When Does Withdrawing the Money Make Financial Sense?
The remaining options involve taking the cash. A scholarship-based withdrawal occupies a middle rank: when a beneficiary receives a tax-free scholarship, the owner can withdraw up to the scholarship amount and pay income tax on the earnings portion but no 10 percent additional tax, an exception Publication 970 also extends to cases involving the beneficiary's death or disability. A nonqualified withdrawal ranks last: the earnings portion is subject to ordinary income tax plus the additional 10 percent tax, and states may claw back prior deductions. Contributions themselves are never taxed on the way out, since they were made with after-tax money; only earnings carry a tax cost, which shrinks the penalty for accounts with modest growth. The distribution is reported on Form 1099-Q, and the taxable earnings calculation follows the proportional method described in Publication 970, allocating each withdrawal between contributions and earnings based on the account's overall ratio.
Frequently Asked Questions About Unused 529 Funds
Is there a deadline to empty a 529 account?
No. Federal law sets no age or time limit on 529 accounts, and funds can remain invested across generations through successive beneficiary changes within the family.
Can leftover funds go to a future grandchild?
Yes. The beneficiary can be changed to a member of the current beneficiary's family, and accounts can be held until a new family member exists to name.
Does the $35,000 Roth rollover renew for each beneficiary?
The lifetime limit applies per beneficiary. Changing the account's beneficiary starts the analysis over for the new beneficiary, subject to the account age and contribution timing rules.
What taxes apply if the family simply cashes out?
The earnings portion of a nonqualified withdrawal is taxed as ordinary income to the recipient plus an additional 10 percent tax, while the contribution portion comes back tax-free.
