For years, families who oversaved in a 529 plan faced an uncomfortable set of options: pay for something that didn’t qualify and absorb a 10% federal penalty plus income tax on earnings, change the beneficiary and hope another family member could use the funds, or simply let the balance sit. That changed when Congress passed the SECURE 2.0 Act in late 2022. Starting with distributions made after December 31, 2023, leftover 529 money can roll directly into a Roth IRA belonging to the account’s beneficiary, up to $35,000 over a lifetime, free of federal income tax and the early-withdrawal penalty.
By mid-2026, accounts opened in the late 2000s are crossing the eligibility threshold for the first time, and families are beginning to navigate the process. The core rules are confirmed. The operational details, in some cases, are not. Here is what you need to know before moving a dollar.
The core rules, confirmed by the IRS
The IRS lays out the mechanics across two publications. Publication 590-A confirms the $35,000 lifetime cap per beneficiary and specifies that each year’s rollover counts against the standard annual Roth IRA contribution limit. For 2025, that limit is $7,000 for people under 50 (per IRS Notice 2024-80). The IRS has not yet published the 2026 figure, though it may adjust upward for inflation. Even at the maximum annual pace, with no competing Roth contributions in those years, a family would need at least five years of transfers to move the full $35,000.
Two timing requirements act as gatekeepers:
- 15-year holding period. The 529 account must have been open for at least 15 years before any rollover can occur.
- Five-year contribution lookback. Contributions made within the most recent five years, along with any earnings attributable to those contributions, are not eligible for rollover.
Both rules appear in the IRS discussion of qualified tuition programs in Publication 970, which now incorporates the SECURE 2.0 rollover language. Several additional requirements are equally important:
- Trustee-to-trustee transfer only. The money must move directly from the 529 plan to the Roth IRA custodian. Withdrawing cash and redepositing it does not qualify.
- Same beneficiary. The Roth IRA must belong to the person listed as the 529 beneficiary. A parent cannot redirect a child’s leftover balance into the parent’s own retirement account.
- Earned income requirement. Because the rollover counts as a Roth IRA contribution, the beneficiary must have earned income at least equal to the amount rolled over in that tax year. A recent graduate who earned $4,500 from a part-time job, for instance, could only roll over $4,500, not the full $7,000.
- Roth income limits do not apply. Unlike regular Roth IRA contributions, the 529-to-Roth rollover is exempt from the modified adjusted gross income (MAGI) phase-out. High earners who are otherwise locked out of direct Roth contributions can still receive these rollovers.
To see how this plays out, consider a practical example: A 529 opened in 2008 for a child who graduated college in 2024 with $28,000 remaining. The account clears the 15-year rule. If no contributions were made after 2019, the five-year lookback is also satisfied. The graduate, now 23 and earning $45,000 a year, could roll $7,000 into a Roth IRA each year for four years, completing the transfer by 2029. That $28,000, invested inside a Roth for four decades, would have decades of tax-free compounding ahead of it.
Where the rules get murky
Congress wrote the statute. The IRS has confirmed the broad framework. But several operational details still lack final administrative guidance, and the gaps are creating real friction for families trying to act.
Beneficiary changes and the 15-year clock. The law refers to how long “the account” has been maintained, but it does not clearly address what happens when a family switches the beneficiary from one child to another partway through. Some 529 plan custodians may treat the original opening date as controlling; others could reset the 15-year clock when a new beneficiary is named. Until the IRS issues specific guidance, families considering a beneficiary change primarily to unlock a rollover should proceed carefully and keep thorough records of all plan correspondence.
Verification by plan administrators. The IRS has referenced forthcoming administrative documents, but detailed procedures telling plan custodians exactly how to verify the 15-year holding period and the five-year contribution lookback have not been finalized. This is especially relevant for account holders who opened plans under a different state program, merged accounts, or transferred between providers over the years. Some custodians may be slower to process rollovers while they wait for clearer instructions.
State tax recapture. Many states offer income tax deductions or credits for 529 contributions. Whether a rollover to a Roth IRA triggers recapture of those prior state tax benefits is not addressed in federal guidance, and states have been slow to clarify their positions. In states with generous 529 deductions, such as New York (up to $10,000 deductible for married filers), Illinois, or Indiana, recapture could meaningfully reduce the net benefit of converting leftover funds. Families in those states should check with their state revenue department or a tax professional before initiating a transfer.
The Roth rollover is not the only option for leftover 529 money
Before committing to the rollover, families should weigh it against other ways to use surplus 529 funds without penalty. The beneficiary could apply the balance toward graduate school, professional certifications, or apprenticeship programs, all of which are qualified 529 expenses. SECURE 2.0 also created a separate provision allowing up to $10,000 in 529 funds to be used for student loan repayment (a lifetime limit per beneficiary). And the account owner can always change the beneficiary to another qualifying family member, such as a sibling, who still has education expenses ahead.
The Roth rollover is most compelling when the beneficiary has genuinely exhausted their education spending, has no student loans (or has already used the $10,000 loan repayment allowance), and no other family member needs the funds. In that scenario, converting leftover savings into a tax-free retirement account is hard to beat.
Why the timing matters in 2026
Accounts opened between 2009 and 2011 are just now crossing the 15-year eligibility threshold, which means the first substantial group of families can begin rollovers in 2025 and 2026. No public data tracks how many 529 accounts satisfy both the 15-year and five-year requirements, but the College Savings Plans Network reported more than 16 million open 529 accounts nationwide as of late 2024, with total assets exceeding $500 billion. Even a small fraction of those accounts holding surplus balances represents a significant pool of potential Roth conversions.
The annual contribution limit creates a built-in pacing constraint. Each year a family delays is a year of Roth contribution space that cannot be recaptured. For a young adult beneficiary, starting the process early also means more decades of tax-free compounding inside the Roth. A 23-year-old who rolls over $7,000 this year and lets it grow at a hypothetical 7% annual return would see that single contribution reach roughly $105,000 by age 65, entirely tax-free on withdrawal.
What to do before you move a dollar
The statutory rules are settled, but the practical experience of using this provision is still new. Before initiating a rollover, families should take these steps:
- Confirm the account’s opening date with the 529 plan administrator, especially if the plan was transferred between states or providers.
- Review contribution history to ensure no deposits were made in the last five years. Request a detailed transaction history if records are unclear.
- Verify the beneficiary’s earned income for the year. The rollover amount cannot exceed what the beneficiary earned, and it must be coordinated with any direct Roth IRA contributions the beneficiary is also making. The combined total cannot exceed the annual limit.
- Check state tax rules. Contact your state’s revenue department or a local tax advisor to find out whether the rollover could trigger recapture of prior deductions or credits.
- Request a direct trustee-to-trustee transfer. Do not take a distribution and attempt to redeposit it. Ask both the 529 plan and the Roth IRA custodian about their specific procedures and processing timelines.
Expect more clarity from the IRS, but don’t wait for it to plan
Congress opened a narrow, tax-favored bridge from long-standing 529 accounts into Roth IRAs. The structural rules are clear and codified. The remaining questions, around beneficiary changes, plan administrator verification procedures, and state tax treatment, are operational rather than existential. The IRS has signaled that additional guidance is forthcoming, but no timeline has been published.
Families with older, overfunded 529 accounts are positioned to benefit the most. The key is to verify every requirement before the money moves, start early enough to use the full $35,000 allowance across multiple years, and stay alert for updated IRS guidance as it arrives. For a young adult who doesn’t need the money for school, converting leftover college savings into a Roth IRA may be the single most valuable financial move their parents’ planning made possible.
