Leftover 529 Money: The Roth Rollover Is Real but Slower Than the Headlines
Leftover 529 money has four exits. The Roth rollover moves one IRA limit a year, so $20,000 takes three years, and cashing out costs 6.6% to 10.2%.
The fall semester bill cleared and there is money left in the 529. The short answer as of August 21, 2026: you have four ways out, none of them a trap, and the one everybody recommends is the slowest of the four. The Roth rollover moves at most one year's IRA contribution limit per year, so a $20,000 balance is a three-year project rather than a form you sign once.
The four are that rollover, a beneficiary change, up to $10,000 of student loan payments, and a plain withdrawal that taxes the earnings. The withdrawal everyone treats as the punishment costs 6.6% to 10.2% of the balance in federal tax. Neither figure appears on the pages that rank for this question.
Two claims are circulating. One says the leftover money is trapped. The other says SECURE 2.0 set it free. A non-qualified withdrawal taxes only the earnings and returns your contributions untouched, so nothing was ever locked in, and the rollover did not free anything either, because it runs through three eligibility tests and the beneficiary's paycheck.
The $35,000 headline is the rule least likely to bind on you
The lifetime cap almost never decides anything. The annual limit does.
Section 529(c)(3)(E)(ii)(II), added by section 126 of the SECURE 2.0 Act, caps these rollovers at $35,000 across the beneficiary's lifetime. It carries no inflation adjustment and applies per beneficiary rather than per account, so a second 529 does not buy a second $35,000. The annual limitation, one clause earlier, meters the money: each year's rollover is capped at the amount applicable under section 408A(c)(2), reduced by her own contributions that year to any IRA. For 2026 the IRA limit is $7,500, set in IR-2025-111 on November 13, 2025, and the transfer has to be direct, trustee to trustee.
Run both rules against a $20,000 balance held by an employed beneficiary with no IRA of her own, and assume every dollar went in more than five years ago. That assumption is doing real work, and the next section takes it away.
Three calendar years, and $15,000 of the $35,000 cap goes unused. Change one input and it stretches: if the beneficiary puts $3,000 a year into her own Roth, annual room drops to $4,500 and the same $20,000 takes five years. That room is not an extra allowance. The rollover eats the space she would have filled herself, which is why the Roth and traditional 401(k) comparison runs on the same limit.
How much of the balance is actually eligible right now?
The 15-year test asks how old the account is. The 5-year test asks how old each contribution is, and only the second one decides how much can move this year.
Section 529(c)(3)(E)(i) requires the program to have been maintained for the 15-year period ending on the distribution date, and separately caps the rollover at contributions made, plus their earnings, before the 5-year period ending on that date. Take a second account, shaped differently: opened in September 2009 with $2,000, left dormant, then funded with $3,000 each September from 2022 through 2025. Contributions total $14,000, and at 6% growth the account holds about $19,300 by September 2026.
At 17 years old it clears the age test easily. The 5-year window runs back to September 2021, so the only seasoned contribution is that original $2,000, now worth $5,385.55 with $3,385.55 of attributable earnings. That $5,385.55, not the balance and not the $7,500 annual limit, is all that can move in 2026, which is 27.9% of the account. The remaining $13,900 or so seasons one deposit at a time: the 2022 contribution in September 2027, the 2023 in 2028, and so on.
Which is what the three-year queue in the last section was quietly assuming away. Nothing here reaches the $7,500 annual limit, so seasoning binds instead of the cap, and clearing this account runs from 2026 to 2030. Five years, with wages needed in every one.
The growth rate and funding pattern are illustrative, and one piece is genuinely unknown: no IRS guidance prescribes how a plan computes "earnings attributable." Ask your administrator for it.
The earned-income rule that IRS Publication 970 never mentions
The beneficiary can never roll over more in a year than she was paid that year. That rule is real, and you cannot learn it from the IRS publications. Publication 970, chapter 7, describes the Roth route in one sentence covering the 15-year account, the 5-year seasoning and the annual limit, and mentions neither the $35,000 cap nor compensation. Publication 590-A states the cap and also omits compensation.
A beneficiary with $5,200 of wages can roll over $5,200, not $7,500, and a full-time graduate student with no wages rolls over nothing. The rule sits three sections deep: section 529(c)(3)(E)(ii)(I) caps the annual rollover at the amount allowed under section 408A(c)(2), which sets that amount as the maximum deductible under section 219. Section 219(b)(1)(B) limits that deduction to the compensation includible in her gross income for the year.
This is why the top of the search results contradicts itself. Fidelity's page, dated May 5, 2026, says "At this time it is unclear if sufficient earned income would be applicable for 529 conversions," while Savingforcollege, updated August 6, 2026, states it flatly as a requirement. Both rank in the top three, so an AI answer here is roughly a coin flip. Check the rule, not the summary you are handed.
The chain runs the beneficiary's way twice. A 401(k) at work does not shrink the rollover, because section 408A(c)(2) ignores section 219(g). And section 408A(c)(3)(E) raises her limit by the rollover amount instead of applying the Roth income phase-out, so a beneficiary earning $200,000, barred from putting a dollar of her own into a Roth, can still receive the full transfer.
Nobody has ruled on whether changing the beneficiary restarts the clock
This one is open, and the evidence that it will stay open is a document nobody reads.
The statute says a distribution from a program "of a designated beneficiary which has been maintained for the 15-year period," and the word "which" can attach to the program or to the beneficiary's account. Practitioners generally assume a beneficiary change resets the clock and advise treating it that way, which is what they agree on and not what Treasury has said. Treasury's 2025-2026 Priority Guidance Plan, released September 30, 2025, lists eight SECURE 2.0 projects by section number and section 126 is not among them. The plan's only 529 item targets the OBBBA expansions instead. A cautious filer picks one route: keep the clock and roll to the Roth over several years, or change the beneficiary and give up the rollover.
Beneficiary changes, student loans, scholarships
The remaining routes are a beneficiary change, student loan payments and the scholarship exception. The K-12 allowance sitting inside the first one doubled in 2026.
Changing the beneficiary carries no income tax if the new one is family, and Publication 970 draws that wide enough to reach in-laws, nieces, nephews, aunts, uncles and first cousins. Moving down a generation raises gift and generation-skipping questions against the $19,000 annual exclusion, which belongs with a preparer. If the new beneficiary is a younger sibling in private school, the OBBBA K-12 cap is $20,000 a year from 2026, up from $10,000, with no age or earned-income test. That clears a five-figure balance in one tax year, but only if there is genuinely that much qualifying tuition to pay in it. Publication 970's 2025 edition still prints the old $10,000.
The student-loan exit pays up to $10,000 of principal and interest over the beneficiary's lifetime, plus a separate $10,000 for each sibling, and interest paid with tax-free 529 earnings is not also deductible. Refinancing student loans under RAP and the RAP plan-change check start where this exit ends.
The scholarship exception is smaller than its reputation: it waives the 10% additional tax up to the scholarship amount and nothing else. On a $12,000 scholarship with a 30% earnings ratio, the waiver saves $360 while income tax on the same $3,600 of earnings still costs $432. Coverage calling this a penalty-free withdrawal has left out the $432.
What the exit toll actually costs
A non-qualified withdrawal of the whole $20,000 costs between $1,320 and $2,040 in federal tax, depending on whose return it lands on.
Your contributions come out tax-free and penalty-free. Only the earnings are taxed, at ordinary rates, plus a 10% additional tax on the same earnings.
| Who receives the check | Marginal rate | Income tax | 10% additional tax | Total | Share of $20,000 |
|---|---|---|---|---|---|
| Graduate, $45,000 salary | 12% | $720 | $600 | $1,320 | 6.6% |
| Parent in the 22% bracket | 22% | $1,320 | $600 | $1,920 | 9.6% |
| Parent in the 24% bracket | 24% | $1,440 | $600 | $2,040 | 10.2% |
Federal tax only, on an illustrative $20,000 carrying $6,000 of earnings against $14,000 of basis, at 2026 rates as of August 21, 2026. Three rows, one withdrawal, three different returns.
Her $45,000 salary minus the $16,100 standard deduction leaves $28,900 taxable, and the $6,000 keeps her at $34,900, inside the 12% band that runs to $50,400. Which return it lands on is a lever you control: the 1099-Q instructions name the beneficiary as recipient when the money goes directly to her, the account owner otherwise. Same account, same $20,000, and $600 of difference that comes entirely from the gap between her 12% bracket and a parent's 22% on the same $6,000 of earnings. The caveat is the kiddie tax, which can pull a student's unearned income onto the parent's rate if she is under 24 and does not support herself. The deciding figure for 2026 is $1,350 under Rev. Proc. 2025-32, which is both the kiddie-tax amount and the floor under a dependent's standard deduction, so the two stack and the trigger usually sits near $2,700. That stacking is my arithmetic, not a figure the revenue procedure prints.
Federal arithmetic is not the whole bill. California treats a 529-to-Roth transfer as non-qualified, taxing the earnings and adding 2.5% on top, and seven other states plus DC recapture deductions or credits you already took, per Ed Slott and Company's survey of October 13, 2025. Positions move, so search your plan's website for "recapture" and "non-qualified" first.
A prompt to sort your own account
Paste this into a chat model with your own figures swapped in. It sorts your numbers into the right tests. It settles nothing, and the grading list under it is the part that matters.
My child graduated and there is $X left in her 529. The account was
opened in [month, year]. Contributions by year: [list them]. She is
[age], [single/married], works [full time/part time] earning $Y, and
contributes $Z a year to her own Roth IRA. We live in [state].
Work through these in order and show the arithmetic for each:
1. Does the account pass the 15-year test as of today?
2. How much of the balance was contributed more than 5 years ago,
and what is the rollover-eligible amount right now?
3. What is my daughter's annual rollover room after subtracting her
own IRA contributions, and how many years to move the whole
balance at that rate?
4. What would a non-qualified withdrawal of the full balance cost in
federal tax, split into income tax and the 10% additional tax?
5. Does my state recapture prior deductions or tax the rollover?
Cite the IRA contribution limit you used and the year it applies to.
Grade the answer in this order. Does it use the 2026 IRA limit of $7,500, or hand back $7,000 from older training data? Does it invent a 2027 limit, when none exists as of August 21, 2026? Does it subtract her own Roth contributions, the step that turns three years into five? Does it test the seasoning separately from the account age? Whatever it says about your state needs checking twice.
Where I land on this
I would price the exit toll before joining the queue, and on these figures the queue still wins. Three years of transfers cost $0 in federal tax against $1,320 for the same $20,000 taken out this month, and the graduate ends up holding a Roth balance instead of a 1099-Q. What flips it is the paycheck. The rollover needs wages in all three years, and none of the numbers above tell you whether she will still be earning in year three. If the money is needed now, 6.6% is a defensible price for the door, and the $600 lever is worth ten minutes first.
The W-4 audit covers withholding on the salary that funds the rollover, the HSA and FSA run shows AI answers going stale at the newest published figure, a mid-year 401(k) checkup works the other contribution limit, and the back-to-school audit covers the smaller end of the budget.
Disclaimer
This is an educational explainer about federal 529 rules, not tax or investment advice, and none of it is specific to your account. The $20,000 balance, the second account's deposit schedule and roughly $19,300 value, the 30% earnings ratio, the 6% growth rate, the salaries and the contribution timelines above are illustrative inputs you replace with your own. The verified figures are the statutory rules, the 2026 IRA limit, the 2026 brackets and standard deduction, and the state survey cited below, each stated as of August 21, 2026 and each subject to change. No IRA limit past 2026 has been published, so the three-year example assumes the 2026 figure holds for two further years and the five-year variants assume it for four, and both say so where they appear. Ask your plan administrator for the seasoning arithmetic on your own account, and take the kiddie tax, generation-skipping questions and state recapture to a tax professional.
