There is a version of the 529-to-Roth rollover that circulates at dinner parties and in comment sections: the government now lets you turn a college fund into a retirement account, tax free, so overfund the 529 and beat the system. Then there is the version written into the SECURE 2.0 Act, which is real, useful, and hedged with enough conditions that most families will touch it later and more slowly than they expect. For parents in their fifties looking at an account their child no longer needs, the difference between the two versions is worth an hour of attention, because the rule rewards people who plan around its clocks and quietly penalizes people who rush it.
What the rule actually says
Since 2024, money left over in a 529 plan can be moved into a Roth IRA belonging to the account's beneficiary without the 10 percent penalty or the income tax that normally hit nonqualified withdrawals. The ceiling is $35,000 per beneficiary over a lifetime, and the account has to satisfy two waiting periods, as Schwab's plain-language summary of the rollover rules lays out: the 529 must have existed for that beneficiary for at least 15 years, and any contributions made in the five years before the rollover, along with the earnings on them, are ineligible.
The destination matters as much as the source. The money goes into the beneficiary's Roth IRA, owned by the beneficiary. A parent cannot route leftover college savings into their own retirement account, at least not without changing the account's beneficiary to themselves, and the prevailing professional reading is that a beneficiary change may restart the 15-year clock. The IRS has not issued definitive guidance on that point, which is itself a reason for caution: anyone building a plan on the aggressive interpretation is building on an unanswered question.
The three clocks
It helps to picture the rule as three separate timers, all of which have to agree before a dollar moves.
The first is the 15-year account age. Families who opened the 529 when the child was small clear this without noticing. Families who started saving in the high school years may find the money locked into education-only status until the beneficiary is pushing thirty, which is a real consideration if the child has already decided against a degree.
The second is the five-year lookback. Because recent contributions and their earnings cannot be rolled, a family hoping to move money soon after graduation needs to stop contributing well before graduation. A reasonable checkpoint is the student's second year: look at the balance, project the remaining bills, and if a surplus is likely, let the account coast from there.
The third is the annual drip. Rollovers count against the beneficiary's regular IRA contribution limit for the year, which the IRS sets at $7,500 for 2026 for people under 50. Moving the full $35,000 therefore takes at least five calendar years of steady transfers. Whatever the word loophole suggests, this is a slow faucet rather than an open drain.
The earned income catch
The condition that surprises the most families is buried in ordinary IRA law: contributions cannot exceed the account owner's taxable compensation for the year. Since a rollover counts as a contribution, the beneficiary needs wages or self-employment income at least equal to the amount moved. A graduate who takes a gap year to travel, or who spends eight months hunting for a first job, has zero rollover capacity that year no matter how old the account is. A daughter earning $5,000 from part-time work can receive a $5,000 rollover, and no more. The parent's income is irrelevant; it is her account, her compensation, her limit.
One piece of genuinely good news hides here. The usual income ceilings that stop high earners from contributing to a Roth IRA do not apply to these rollovers, so a beneficiary who lands a lucrative job remains eligible. And for a young adult, the arithmetic of an early Roth balance is striking: $35,000 compounding untaxed at an assumed 7 percent annual return grows to roughly half a million dollars over forty years, without another dollar added. Parents who work the timers correctly are effectively handing their child a retirement head start that costs the child none of their early-career take-home pay.
Your state may want its money back
The federal government treats a compliant rollover as tax free. Your state may see it differently, and this is where the plan's shine dulls for some households. States that gave you a deduction or credit for 529 contributions sometimes classify a Roth rollover as a nonqualified withdrawal, which can trigger recapture of those old tax breaks. Indiana's credit clawback works this way, New York has recapture rules of its own, and California, which never offered a deduction, applies an additional 2.5 percent state tax to the earnings portion of withdrawals it deems nonqualified. On an account with decades of growth, that is not a rounding error.
The practical move is unglamorous: before initiating anything, read your own plan's disclosure booklet on nonqualified withdrawals and, if the numbers are large, spend a modest fee on a session with a tax professional who knows your state. This article is general information; state rules shift year to year, and a strategy that is clean in one zip code can carry a four-figure cost in another.
The other 2026 change, and when it beats the rollover
The Roth rollover is no longer the only exit for surplus college money. Federal law has allowed 529 withdrawals for elementary and secondary tuition since 2018, historically capped at $10,000 per year, a figure the IRS's own 529 guidance still describes. Legislation enacted in 2025 raises that cap to $20,000 beginning with the 2026 tax year. For a family with an overfunded account and a younger child in private school, redirecting the surplus toward tuition that would otherwise come from current income or loans can be worth more, sooner, than a five-year drip into a Roth. Grandparents doing legacy planning have a similar menu: change the beneficiary to a grandchild for future education, spend it on K-12 tuition, or run the rollover for a grandchild with earned income, mindful of the clock questions above.
A short honesty check before you optimize
The quiet truth underneath all of this is that genuinely overfunded 529s are less common than the coverage implies. Typical balances sit far below the full cost of a degree, and most surpluses exist because a student won scholarships, chose a cheaper path, or finished early. If that is your situation, the sequence that works looks like this:
- Confirm the account has been open for the beneficiary for 15 years, and treat any beneficiary change as a question for a professional first.
- Stop new contributions at least five years before you expect to start rollovers.
- Make sure the beneficiary has earned income in each year money moves, and size each transfer to the smaller of their compensation or the annual IRA limit.
- Check your state's recapture rules before the first dollar leaves the plan.
- Track the lifetime total across years so the family stays under $35,000.
Handled this way, the provision does exactly what Congress apparently intended: it removes the old fear that money saved for an education which never happens is trapped behind a penalty. What it does not do is turn a college account into a fast lane for retirement wealth. Families who accept the slow faucet get a real gift out of it. Families who fight the timers mostly get correspondence from tax authorities.
