529 Plans and Grandchildren: The SECURE 2.0 Roth Rollover Changes Everything

Two changes — one regulatory, one legislative — have made grandparent-owned 529 plans substantially more attractive than they were before 2024. The first: the 2024–25 FAFSA reform eliminated the longstanding financial aid penalty that made grandparent-owned 529 distributions count as student income and reduce need-based aid eligibility. The second: SECURE Act 2.0 (effective January 1, 2024) added a provision allowing unused 529 funds to roll directly into a Roth IRA for the beneficiary, tax-free and penalty-free, up to a $35,000 lifetime limit.

Together, these changes resolve the two objections that historically made grandparents hesitant to use 529 plans: the fear that distributions would hurt the grandchild's financial aid, and the fear that unused funds would be trapped and subject to a 10% penalty on earnings. Neither concern applies under the current rules.

For grandparents with meaningful assets to transfer, the 529 plan now combines three things in a single structure: tax-free education funding, estate planning with retained control, and a retirement savings head start for the grandchild if education funds go unused.

How 529 Plans Work

A 529 plan is a tax-advantaged savings account established under Section 529 of the Internal Revenue Code and administered at the state level. Each state operates its own plan (or plans), but you can contribute to any state's plan regardless of where you or the beneficiary lives — the grandchild doesn't need to attend college in the state whose plan you use.

The account owner — the grandparent — retains full control over the account at all times. The owner names a beneficiary (the grandchild), makes contribution and investment decisions, and can change the beneficiary to another eligible family member at any time. Contributions are made with after-tax dollars and grow tax-deferred. Withdrawals used for qualified education expenses — tuition, room and board, books, computers, registered apprenticeship programs, and K–12 tuition up to $10,000/year — are entirely tax-free at the federal level.

There are no income limits to contribute, no annual deadlines, and no age restrictions on the beneficiary. The only federal limitation is that contributions cannot exceed the account balance needed to pay for the beneficiary's anticipated qualified education expenses — a threshold that in practice is rarely reached given contribution limits.

The FAFSA Reform: The Grandparent Loophole Is Now Official Policy

Before the 2024–25 academic year, grandparent-owned 529 plan distributions created a significant financial aid problem. Under the old FAFSA formula, distributions from grandparent-owned plans were counted as untaxed student income — assessed at 50% toward the Expected Family Contribution. A $20,000 distribution from a grandparent's 529 could reduce need-based aid eligibility by up to $10,000. This pushed many grandparents to use workaround strategies: waiting until the student's final year, transferring ownership to the parent, or simply not using a 529.

Starting with the 2024–25 FAFSA, the Department of Education revised the Student Aid Index formula to remove this treatment entirely. Distributions from grandparent-owned 529s are no longer reported on the FAFSA at all — they are not counted as student income, and grandparent assets are not reportable on the FAFSA. A grandparent can distribute funds from their 529 to pay for a grandchild's tuition in any year without any effect on FAFSA-based financial aid eligibility.

One exception worth noting: the CSS Profile, used by approximately 400 private colleges and universities for institutional aid, may still ask about grandparent 529s and treat distributions differently. The FAFSA reform does not govern CSS Profile treatment. Families applying to selective private colleges should check each school's CSS Profile treatment before assuming the grandparent ownership advantage is fully portable.

Superfunding: Removing Up to $190,000 from Your Estate Per Grandchild in Year One

The annual gift tax exclusion in 2026 is $19,000 per donor per recipient — meaning a grandparent can contribute $19,000 per year per grandchild to a 529 without any gift tax filing requirement. For a couple with four grandchildren, that's $152,000 per year in estate removal with no reporting requirement.

But 529 plans offer an additional mechanism: superfunding, or 5-year gift tax averaging. Under IRC Section 529(c)(2)(B), a donor can make a lump-sum contribution of up to five times the annual exclusion — $95,000 per grandchild from a single grandparent, or $190,000 from a couple — in a single year and elect to spread the gift over five years for gift tax purposes. The full amount is treated as a completed gift and is removed from the taxable estate immediately, but no gift tax is owed because the five-year averaging keeps the annual equivalent at or below the exclusion amount.

The mechanics require filing IRS Form 709 (Gift Tax Return) in the year of the contribution to make the five-year election. No gift tax is owed, but the form is required. One important caveat: if the grandparent dies before the five-year period expires, the unelapsed pro-rated portion of the superfunding contribution is included back in the gross estate. A grandparent who superfunds $190,000 and dies two years later has three-fifths of the contribution — $114,000 — re-included in their estate.

The strategic advantage of front-loading is significant. A $95,000 contribution in year one, growing at 6% annually, reaches approximately $127,000 by year five. Spreading $19,000/year over five years with the same growth rate reaches approximately $107,000 — a $20,000 difference from earlier compounding. With a 13–18 year horizon before college, the superfunding advantage compounds substantially.

The SECURE 2.0 Roth Rollover

Section 126 of the SECURE Act 2.0 added a new qualified distribution type for 529 plans: a direct rollover to a Roth IRA for the account's designated beneficiary, effective January 1, 2024. This provision directly addresses the "trapped money" objection — the fear that if a grandchild doesn't use all the 529 funds for education, the earnings are stuck and subject to income tax plus a 10% penalty on non-qualified withdrawals.

The Roth rollover eliminates that penalty entirely for up to $35,000 per beneficiary, subject to five specific conditions.

The Five Conditions

Condition 1 — 15-year account age: The 529 plan must have been maintained for the designated beneficiary for at least 15 years. The clock runs from the account's original opening date for that beneficiary. Whether changing a beneficiary resets the clock is an unresolved IRS question — most practitioners assume it does, so plan accordingly.

Condition 2 — Roth IRA in the beneficiary's name: The rollover goes into a Roth IRA owned by the 529's designated beneficiary — not the grandparent. The rollover must be made as a direct custodian-to-custodian transfer; the grandparent cannot receive a check and deposit it into a Roth.

Condition 3 — Annual rollover limited to Roth IRA contribution limit: The amount rolled in any year cannot exceed the annual Roth IRA contribution limit applicable to the beneficiary — $7,500 in 2026 for those under 50, $8,600 for those 50 or older. Any other Roth IRA contributions for the year count toward this limit. At $7,500/year, reaching the $35,000 lifetime cap takes a minimum of five years.

Condition 4 — Five-year contribution seasoning: Only contributions (and their earnings) that have been in the 529 for at least five years prior to the rollover date are eligible. Contributions made in the last five years cannot be rolled over even if the account is 20 years old.

Condition 5 — $35,000 lifetime cap per beneficiary: The total lifetime rollover across all years cannot exceed $35,000 per beneficiary. Importantly, the Roth IRA income limits that normally bar high earners from contributing to a Roth — $165,000+ for single filers in 2026 — do not apply to 529-to-Roth rollovers. A grandchild earning $300,000 can still receive this rollover. This makes the provision especially valuable for high-earning grandchildren who otherwise have no path to Roth contributions.

The beneficiary must also have earned income in the year of the rollover at least equal to the rollover amount — the same earned income requirement that applies to all Roth IRA contributions.

The Long-Run Value of $35,000 in a Roth at Age 22

The lifetime $35,000 cap sounds modest, but its long-run value is not. $35,000 in a Roth IRA at age 22, growing at 6% annually with no additional contributions, reaches approximately $360,000 in tax-free assets by age 62. That is entirely tax-free — no RMDs, no income tax on withdrawals — from what might otherwise have been unused 529 funds subject to a 10% penalty on earnings. The conversion from "trapped education savings" to "retirement head start" is one of the most tax-efficient financial moves now available to families.

What to Do with Leftover 529 Funds

In order of tax efficiency:

1. Use for remaining qualified education expenses — tuition, room and board, books, registered apprenticeship, K–12 tuition up to $10,000/year, or student loan repayment up to $10,000 lifetime
2. Change beneficiary to another eligible family member — sibling, cousin, parent, even the grandparent themselves — eligible family members are broadly defined under Section 529
3. Roll over to the beneficiary's Roth IRA — up to $35,000 lifetime, subject to the five conditions above
4. Leave in the account for the next generation — redirect to a grandchild's child when the time comes; the 529 can serve multiple generations
5. Non-qualified withdrawal — last resort; earnings subject to ordinary income tax plus 10% federal penalty (the principal can always be withdrawn penalty-free since it was contributed after-tax)

The scholarship exception provides one additional option: if the beneficiary receives a scholarship, the grandparent can withdraw an amount up to the scholarship value as a non-qualified distribution — the 10% penalty is waived, though income tax on the earnings still applies.

Choosing the Right Strategy by Grandchild's Age

The right 529 approach depends primarily on how much time exists before college and whether the 15-year Roth rollover clock has already started.

Newborn to age 5 — The Long-Horizon Superfund: Open immediately and superfund up to $190,000 per couple. The estate planning benefit is maximized; the compounding period is longest; and the 15-year Roth rollover clock starts now, expiring when the grandchild is around 15–20 — right at the start or completion of college, when the Roth rollover is most useful.

Age 6–12 — Annual Contributions with Roth Prep: Annual contributions of $19,000/year capture state tax deductions while building the account. If the account was opened at birth, the 15-year clock is already running and will reach eligibility when the grandchild is in their early twenties — ideal timing for Roth contributions in their first post-college working years.

Age 13–17 — College-First, Roth-Later Hybrid: The investment horizon to college is short — shift to lower-risk allocations. Contribute enough to cover projected education costs. If the account was opened early, the 15-year clock is already satisfied or nearly so. Deliberately retain at least $35,000 in the account after college for Roth rollover use — this is far more valuable than a non-qualified withdrawal.

College-age and beyond — The Roth Conversion Safety Valve: If the account has been open 15+ years and education costs are fully covered, begin the annual Roth rollover immediately. Coordinate with the grandchild to ensure they have a Roth IRA open and sufficient earned income in each rollover year.

Estate Planning Considerations

For grandparents with taxable estates, 529 plans offer a uniquely flexible estate-reduction tool. A superfunding contribution of $190,000 per grandchild removes that amount from the taxable estate immediately — as a completed gift — while the grandparent retains full ownership and can change the beneficiary or redirect the funds if circumstances change. This combination of immediate estate removal and retained control is available through very few other planning structures; an irrevocable trust achieves estate removal but surrenders control permanently.

For a couple with four grandchildren, superfunding all four removes $760,000 from the taxable estate in a single year, all growing tax-free and eventually distributable for education or via Roth rollover — without any loss of grandparent control during their lifetimes.

A successor owner should always be named on every grandparent-owned 529. If the grandparent dies without naming a successor owner, account control and ownership becomes a probate matter — the estate planning benefit is preserved for the assets, but the grandparent's intent around beneficiary and distribution control is lost.

Important Notes

• State deduction optimization: In states that offer a deduction only for in-state plan contributions (about 27 states), residents must weigh the deduction value against the investment quality of their state's plan. For states with no income tax (including Florida, Texas, Washington, Nevada) or no 529 deduction (including California), residents should comparison-shop all state plans and choose the one with the best investment options and lowest expense ratios — Nevada, Utah, and New York plans are consistently highly rated.
• The income limit exception is significant and real: The Roth IRA income phaseout does not apply to 529-to-Roth rollovers. This is explicitly provided in the statute. High-earning grandchildren who are otherwise completely ineligible for Roth contributions have a backdoor path via this rollover.
• Earned income requirement: The beneficiary must have earned income in the rollover year at least equal to the rollover amount. Passive income, investment income, and Social Security do not qualify — the beneficiary must have wages or self-employment income.
• The $35,000 cap is per beneficiary across all 529 accounts: If a grandchild has two 529 accounts — one from each set of grandparents — the $35,000 lifetime Roth rollover cap applies to the combined total across both accounts, not $35,000 per account.
• CSS Profile schools: The 2024 FAFSA reform that eliminated the grandparent 529 financial aid penalty applies only to FAFSA. The CSS Profile, used by about 400 selective private colleges, may still ask about grandparent-owned 529s and assess them differently. Families with grandchildren applying to CSS Profile schools should research each school's treatment.
• Beneficiary changes and the 15-year clock: If the 529 beneficiary is changed to a younger-generation relative, the gift tax rules may treat the change as a new gift, and some practitioners believe the 15-year clock restarts. This is not definitively resolved in IRS guidance — treat a beneficiary change as potentially resetting the clock for rollover planning purposes.
• 529 plans cannot be directly rolled into a traditional IRA — only a Roth IRA. The Roth rollover provision is specific to Roth accounts.
