Unlocking the Hidden Power of Unused 529 Plans: How They Can Now Boost Retirement Through Roth IRA Transfers

For decades, 529 plans have been a go-to vehicle for families seeking tax-advantaged ways to save for a child’s education. However, a common concern has lingered in the background: what if the beneficiary doesn’t need all—or any—of the money?

A child may decide not to attend college. Or they might get a full-ride scholarship, qualify for employer assistance, or simply choose a less expensive route, like community college or vocational training. In these cases, families are left wondering: What happens to the leftover 529 funds?

Thanks to the SECURE 2.0 Act, passed at the end of 2022, a new and powerful solution has emerged. Under certain conditions, families can now transfer unused 529 assets—tax- and penalty-free—into a Roth IRA for the same beneficiary, potentially giving their child a significant head start on retirement savings.

Let’s dive deeper into how this rule works, why it matters, and how you can use it to your advantage as part of a long-term financial and retirement plan.

The 529 Plan: A Quick Overview

529 plans were created to help families save for education in a tax-advantaged way. Contributions grow tax-deferred, and withdrawals are tax-free when used for qualified education expenses.

Additional benefits include:

• Gift tax exemptions: In 2025, individuals can contribute up to $19,000 per year (or $38,000 per couple) without triggering federal gift taxes. Donors can also front-load five years’ worth of contributions—up to $95,000 per person, per beneficiary.
• State tax advantages: While federal deductions aren’t available, many states offer tax deductions or credits for 529 contributions.

But if 529 funds are withdrawn for non-qualified purposes, earnings are subject to ordinary income tax and a 10% federal penalty. That’s where the Roth IRA rollover option shines.

Roth IRA Transfers: A Game-Changer from SECURE 2.0

The SECURE 2.0 Act introduced a new provision that allows certain 529 assets to be rolled over to a Roth IRA in the name of the 529 plan’s beneficiary. This opens a tax-smart pathway for unused education funds to continue compounding tax-free—this time, for retirement.

Key Rules to Know

To qualify for a 529-to-Roth rollover, several criteria must be met:

1. 15-Year Rule: The 529 plan must have been open for at least 15 years.
2. Contribution Age: Funds being transferred must have been contributed to the 529 at least five years before the rollover.
3. Annual Contribution Limits Apply: Transfers count toward the beneficiary’s annual Roth IRA contribution limit ($7,000 in 2025, or $8,000 if age 50+).
4. Lifetime Cap: A maximum of $35,000 per beneficiary can be rolled over.
5. Earned Income Requirement: The beneficiary must have earned income in the calendar year the rollover occurs, equal to or greater than the amount transferred.
6. Beneficiary Ownership: The Roth IRA must be in the name of the 529 plan’s beneficiary—not the parent or account owner.
   These requirements ensure the tax benefit is used thoughtfully, mirroring the same income and contribution limits that typically apply to Roth IRAs.

Meet Carol: A Hypothetical Success Story

To better understand how this strategy works in real life, let’s consider the case of Carol.

Carol is 22, and her parents opened a 529 account for her years ago. The account has grown to $30,000—composed of $20,000 in contributions and $10,000 in gains. However, Carol decides to skip college and pursue a career as a freelance graphic designer.

Without the SECURE 2.0 Act, her parents would face the unpleasant choice of withdrawing the funds for non-qualified use and paying income taxes plus a 10% penalty on the $10,000 in earnings—adding up to $3,500 in taxes and penalties at a 25% tax rate.

Instead, Carol’s parents now have a smarter choice: roll over the funds into a Roth IRA in Carol’s name.

Given the $7,000 annual contribution limit for 2025, the rollover would look like this:

Over the course of five years, Carol can transition all $30,000 into her Roth IRA.

The Long-Term Power of Early Roth Contributions

Roth IRAs grow tax-free and withdrawals in retirement are not taxed—making them one of the most valuable vehicles for long-term savings.

Assume Carol doesn’t touch the Roth funds and earns a 7% annual return. By the time she reaches retirement age at 67, her $30,000 rollover could grow to $449,234—all tax-free.

That’s the magic of compounding over 40+ years.

Income Considerations and Potential IRS Guidance

One question that still lingers: how will the IRS interpret the income requirements for Roth IRA rollovers from 529s?

As of now, Roth contributions require the individual to have earned income equal to or greater than the amount contributed. However, SECURE 2.0’s text does not explicitly address this requirement for 529 rollovers. While many financial professionals assume earned income will still be required, official IRS guidance is expected to clarify this.

Other potential complications include:

• The beneficiary earning too little to contribute the full $7,000.
• The beneficiary already contributing the maximum to a traditional or Roth IRA through other sources.
• The beneficiary exceeding income limits for regular Roth contributions—though this doesn’t currently appear to disqualify 529 rollovers.

Until further clarification is available, it’s wise to proceed cautiously and consult with a tax advisor to ensure compliance.

Strategic Planning Tips

This new rollover opportunity doesn’t just resolve the “what-if” of unused 529s—it opens the door to new strategies:

1. Start a 529 Early: Even if your child is young, opening a 529 now can help you meet the 15-year requirement down the road.
2. Overfund with Intention: Consider overfunding a 529 plan slightly with the understanding that unused funds can become a retirement asset.
3. Think Multi-Generational: If one child doesn’t use the funds, you can change the beneficiary to another family member or use it for a Roth IRA rollover.
4. Watch the 5-Year Rule: Make sure contributions earmarked for future Roth conversions are at least five years old at the time of transfer.

Final Thoughts: A Bridge Between Education and Retirement

The ability to convert unused 529 funds into Roth IRA assets is more than just a workaround for leftover education money—it’s a powerful, strategic link between two pillars of financial planning: education and retirement.

Whether you’re a parent looking to help your child start life with a financial cushion, or a grandparent hoping to create a legacy of smart savings, this rule creates new flexibility and new possibilities.

As always, planning ahead—especially with long-dated tools like 529 plans and Roth IRAs—is key. And as the IRS continues to issue clarifying guidance on this provision, staying informed and working with a knowledgeable financial advisor will ensure you’re making the most of these new opportunities.

In a world where college plans may change, but retirement always comes, the 529-to-Roth rollover may just be the smartest Plan B you’ll ever make.
