529 to Roth rollovers: What advisors and families are still getting wrong

Back-to-school season is here, and for high-net-worth families sending a child to college for the first time, the financial planning conversations have changed materially since the SECURE 2.0 Act of 2022 took effect. Section 126 of SECURE 2.0 allows beneficiaries to roll unused 529 plan assets into a Roth IRA — subject to a $35,000 lifetime cap per beneficiary, annual Roth IRA contribution limits (currently $7,000 in 2026, or $8,000 for those age 50 and older), a 15-year account seasoning requirement, a five-year contribution aging requirement, and an earned income requirement equal to the amount being rolled over. The provision does not limit the total 529 balance — only the rollover. It also does not eliminate income limits on Roth IRA contributions, since the rollover is treated as a direct 529-to-Roth transfer rather than a standard contribution.

Three advisors who work with HNW families heading into college-funding season explain what the rule actually does, where families and their advisors keep getting it wrong, and how it changes the strategic calculus for 529 planning from day one.

Start the clock early — beneficiary changes reset the 15-year timer

Michelle Riiska, senior financial planning product and research consultant at eMoney Advisor, says the 529-to-Roth rollover has done something structurally important for families who were previously hesitant to fund 529 plans: it has reduced the perceived risk of overfunding an account for a child who might not pursue traditional higher education.

The most important planning implication of that shift, in Riiska's view, is timing. The 15-year seasoning requirement means that families who want access to the rollover option as early as possible need to establish the 529 account and begin contributing — even in small amounts — as early as possible. A family that opens a 529 at the child's birth can potentially begin rolling funds into a Roth IRA as early as age 15, whereas a family that waits until the child is 10 to open the account faces a 25-year delay before full rollover eligibility.

"The availability of Roth conversions allows 529 accounts to be used with more confidence that the funds will benefit the beneficiary, regardless of future education choices. For students heading into freshman year with a generously funded 529, there is additional incentive to seek out scholarships and grants since any funds left, up to $35,000 per individual, can be rolled over and used as a jump start on retirement savings," Riiska said.

Riiska also flags a mistake that is easy to make inadvertently: changing the beneficiary on an existing 529 resets the 15-year clock to zero. Under current IRS guidance, the seasoning period runs from the date the account is established for the current beneficiary — not from the account's original opening date. A family that consolidates two 529 accounts by changing the beneficiary on one of them may unknowingly forfeit years of seasoning history. Her recommendation is to establish a separate 529 for each child from the outset and to be deliberate about any beneficiary change before making it. 

Most sophisticated investors still don't know this opportunity exists

Jason Stephens, founder and managing partner of Evertern Wealth, says the most common misconception among advisors and families is simply that many of them have never heard of the rollover provision at all.

The rule has been in effect since January 2024, yet Stephens regularly encounters highly sophisticated investors who have no awareness of it or who misunderstand its mechanics in one of several predictable ways. The most common misunderstanding is that any unused 529 balance can be transferred to a Roth IRA immediately and without restriction. In practice, the five-year contribution aging requirement means that contributions made within the most recent five years — and earnings on those contributions — are not eligible for rollover. The beneficiary must also have earned income equal to the amount being rolled over in the applicable tax year, meaning a college freshman without a job cannot roll over funds regardless of the account's seasoning status.

"We increasingly view a 529 plan not simply as an education funding vehicle, but as part of a family's broader tax, retirement, and wealth transfer strategy. Rather than viewing excess education savings as a potential problem, families can now help launch their children's retirement savings decades earlier than most young adults ever would on their own," Stephens said.

Stephens also notes that the rollover is not always the best first option when a 529 has funds left over after college. Changing the beneficiary to another child, grandchild, or future family member remains a viable and often preferable alternative — particularly for families where a younger sibling or grandchild is likely to use the funds for education expenses. The $35,000 lifetime rollover cap is per beneficiary, which means families who plan ahead can stack rollover eligibility across multiple beneficiaries by establishing separate accounts early. 

The FAFSA impact and the five-year aging rule are the two most missed details

Kathy Costas, vice president, financial advisor, and partner at EP Wealth Advisors, brings two specific mechanics to the conversation that advisors frequently overlook when presenting the 529-to-Roth rollover to families.

The first is the FAFSA impact. Under the current FAFSA methodology, a 529 plan owned by a parent counts as a parental asset, and the formula assumes that 5.64% of parental assets will be available for educational expenses in each academic year. The FAFSA treatment does not change because of the Roth rollover option — families considering whether to fund a 529 aggressively still need to weigh the potential effect on financial aid eligibility against the tax advantages and rollover flexibility the account provides. For families with meaningful financial aid potential, the calculation is not straightforward.

"There is no doubt that this is a beneficial change to the use of a 529 as a planning tool since it broadens the scope from just education planning to long-term retirement planning as well. But the devil is in the details, so it's important to have a solid plan that maximizes the benefit of these accounts," Costas said.

The second detail Costas highlights is the five-year contribution aging requirement, which she says is consistently misread by both families and their advisors. Parents frequently assume that any funds sitting in a 529 account can be rolled over once the 15-year seasoning period is met. The five-year rule operates independently: only contributions that have been in the account for at least five years — and earnings on those specific contributions — are eligible. Contributions made within the most recent five years are excluded from rollover eligibility regardless of how long the account itself has been open. The combined effect is that a family cannot backload contributions into a 529 the year before a child graduates and expect to roll those funds into a Roth IRA immediately. The legislation was deliberately designed to reward sustained, incremental savings behavior rather than last-minute funding. 

Taken together, the three advisors describe a provision that is genuinely valuable — but whose value depends almost entirely on understanding the timing requirements before making decisions that cannot be easily reversed. Families who open 529 accounts early, make consistent contributions, avoid unnecessary beneficiary changes, and plan the rollover strategy in coordination with their financial, tax, and estate planning advisors are the ones most likely to maximize what SECURE 2.0 actually makes available. Those who assume the headlines have told them everything they need to know will encounter the rules at an inconvenient moment.
