A listener wrote in saying their family funded a 529 for their daughter starting when she was born, and that their daughter ended up receiving a significant scholarship that left more in the account than they ever expected to need. They were asking how the SECURE 2.0 529-to-Roth rollover actually works in practice, because the headlines around the provision have made it sound like a clean escape hatch for over-funded 529 accounts. It is a useful tool, but the fine print is more restrictive than the marketing language suggested. Here is what families should actually expect.
Why This Provision Got So Much Attention
SECURE 2.0, signed at the end of 2022 and taking effect in 2024, gave families a brand new option for leftover 529 dollars. Before the law passed, the realistic choices for over-funded 529s were limited. You could change the beneficiary to a different family member. You could withdraw the money and pay both ordinary income tax on the earnings and a 10% penalty on top, unless a specific exception applied. Or you could leave the money in the account and hope to use it later. The Roth rollover provision opened a clean path for families with high-achieving kids on scholarship and for anyone who, in hindsight, simply put more money in than the education ultimately required. The headlines read like a complete escape hatch. The actual rules are tighter.
The Five Rules That Cap the Real Benefit
There are five constraints that, in combination, shape how much of any given 529 can actually move into a Roth. First, the 529 must have been open for at least 15 years before any rollover can happen. Second, the amount you can roll over in any year is subject to that year’s annual Roth contribution limit, currently $7,000 for those under 50. Third, the lifetime cap on rollovers is $35,000 per beneficiary. Fourth, the beneficiary must have earned income in the year of the rollover, and the rollover amount cannot exceed that earned income. Fifth, contributions made to the 529 in the last five years, and any earnings on those contributions, are ineligible to be rolled. Each rule on its own is reasonable. Stacked together, they meaningfully shrink what families can move.
Working Through the Math on a Real Example
Take the scholarship scenario from the listener. Suppose $80,000 is sitting in the 529 after the daughter wraps up undergraduate study. At best, the family rolls $7,000 per year, in years when the daughter has at least that much earned income, for five consecutive years. That gets the cumulative rollover to $35,000 and triggers the lifetime cap. The remaining $45,000 is still inside the 529 and needs another solution. The math gets tighter if the daughter’s earned income in some of those years is below the contribution limit, or if she contributes separately to her own Roth, which tightens the rollover ceiling further. The provision is genuinely useful, but it is not an answer for the full leftover balance in most cases.
What Else You Can Do With Leftover 529 Funds
The good news is the rollover is not the only tool. The beneficiary on a 529 can be changed at any time to another qualifying family member: a sibling, a niece or nephew, a future grandchild, or even one of the parents who might be eyeing a graduate program down the road. That flexibility alone makes a 529 a multi-generational asset rather than a single-child savings vehicle. There is also a specific scholarship exception that surprises families when we walk them through it. If your child received a scholarship, you can withdraw up to the scholarship amount from the 529 without the 10% penalty. You still owe ordinary income tax on the earnings portion, but the IRS effectively does not penalize you for your child outperforming expectations. That carve-out alone can rescue a meaningful chunk of an over-funded 529.
Why the Roth Rollover Is Still Worth Doing First
Even with the caps, the rollover is usually the best first move. Think about what $35,000 sitting in a Roth IRA at age 22 or 23 actually becomes. At a 7% average annual return, that money roughly doubles every ten years. Over forty years of compounding it becomes north of half a million dollars, tax-free, in the beneficiary’s hands at retirement. That is a meaningful head start for someone who has barely begun their working career. The full leftover may not all move through the Roth, but starting the rollover process early in the right years can set up the next generation in a way that almost nothing else in the planning toolkit replicates. The rollover is not the whole solution to an over-funded 529. It is just usually the first piece worth using.
