What to Do with Leftover 529 Funds | 5 Smart Strategies

Wondering what to do with leftover 529 plan funds after college? A common financial problem I see is 529 plans with money left over once paying for college is finished. Sometimes it’s a couple thousand dollars, sometimes it’s $100,000, like in the case of a client of mine who had won a substantial scholarship. When withdrawn from the plan for non-college expenses, the growth portion of money will be taxed plus a 10% penalty, ouch!

Here are 5 strategies that I use to eliminate or minimize these taxes and penalties.

1.     Fund another family member’s education.

If one child bypasses college, or does not use all the funds, you can easily change the account beneficiary to another eligible family member with zero penalty or tax consequences. The IRS defines "family member" incredibly broadly. You can transfer the funds to:

• Siblings, or stepsons/stepdaughters
• First cousins, nieces, or nephews
• Yourself (the parent) or your spouse to fund continuing education or professional certifications

Because 529 plans have no expiration date, you can also leave the funds in the plan to compound tax-deferred for future grandchildren.

2.     Roll over leftover 529 money to a Roth IRA. ( SECURE Act 2.0)

Thanks to the SECURE Act 2.0, you can now transition leftover education funds directly into a tax-free retirement nest egg for your child. You can roll over up to a lifetime limit of $35,000 from a 529 plan into a Roth IRA owned by the beneficiary.

However, the IRS has strict guardrails to keep in mind:

• The 15-Year Rule: The 529 account must have been open for at least 15 years.
• The 5-Year Rule: Any contributions (and their earnings) made within the last 5 years cannot be rolled over.
• Annual Limits Apply: You can't move all $35,000 at once. The transfer is subject to annual Roth IRA contribution limits. For 2026, the annual limit is $7,500 (meaning a full $35,000 rollover will take about 5 years to complete).
• Earned Income Required: The beneficiary must have earned income at least equal to the amount being rolled over that year.

3.     Pay down student loan debt. ($10,000 Lifetime Limit)

Did your student finish school but graduate with some debt? Or perhaps a sibling took out loans? You can use a lifetime maximum of $10,000per individual from a 529 plan to pay down qualified student loans. This applies to both the primary beneficiary and any of their siblings, offering a clean way to wipe out a chunk of debt tax-free.

4.     Pay for other types of education.

A 529 plan isn't exclusively reserved for traditional four-year universities. It can also cover:

• Trade and Vocational Schools: Tuition and equipment for registered apprenticeship programs, technical training, or career credentials.
• K-12 Tuition: You can withdraw up to $20,000 per year, per beneficiary (federally) to cover elementary or secondary private or religious school tuition.
• Alternative Programs: Any post-secondary institution eligible for federal student aid (including many international universities and culinary schools) counts.

5.     Take a penalty free scholarship withdrawal.

If your child didn’t need the 529 money because they won a scholarship, you can withdraw cash up to the exact dollar amount of that scholarship.

While you will have to pay ordinary income tax on the earnings portion of that withdrawal, the IRS waives the usual 10% penalty for non-qualified distributions in this specific scenario. The original principal contributions you made are always withdrawn tax- and penalty-free.

Bonus: Take advantage of low tax brackets for an early graduate

In the case none of these options are a good fit for you, and you need to withdraw money normally, it may not be as painful as it sounds. A recent graduate is often in a low-income phase of life and may be able to withdraw from the plan in a very low tax bracket, although the 10% penalty on the earnings portion still applies. This can be done by sending the distribution directly to the beneficiary of the plan, so the income ends up on their tax return.

Conclusion

529 plans are the most commonly used investment account type for funding college due to the tax advantages they offer. While having unused funds left in a 529 account can initially feel like a tax headache, these options demonstrate that a 529 plan is more versatile than most people realize. Whether you choose to roll funds over into a Roth IRA, support another family member’s education, or strategically navigate low tax brackets, there are many options available to avoid paying penalties or taxes.

Before making a final decision on any of these strategies, be sure to consult with your financial advisor and CPA to review state-specific tax laws and ensure any planned moves strictly adhere to IRS timing requirements. Many of our Issaquah and Bellevue based clients will soon be subject to Washington’s new income tax, which will require state specific planning. However, with a clear strategy, leftover 529 funds can easily transition from a tax headache to a valuable start on your family's broader financial goals.

Frequently Asked Questions

Can I roll over leftover 529 funds into a Roth IRA without paying taxes?

Yes, under the SECURE Act 2.0, you can roll over up to a $35,000 lifetime limit of leftover 529 funds into a Roth IRA owned by the beneficiary without federal income taxes or penalties. To qualify, the 529account must have been open for at least 15 years, and contributions made within the last 5 years are ineligible. Rollovers are subject to annual Roth IRA contribution limits (e.g., $7,500 in 2026), meaning a full $35,000 transfer must be spread over several years.

What is the penalty for withdrawing unused 529 money for non-education expenses?

If you take a non-qualified withdrawal, you will pay ordinary federal income tax (plus applicable state income taxes) on the earnings portion of the account, along with a 10% IRS tax penalty. However, your original contributions are returned completely tax- and penalty-free, as that money was contributed with after-tax dollars.

Can I transfer a 529 plan to another child or family member?

Yes. You can change the beneficiary of a 529 plan at anytime to another eligible family member with zero tax consequences or penalties. The IRS defines eligible family members broadly, including siblings, stepchildren, first cousins, nieces, nephews, and even yourself (the parent).

Can I use leftover 529 money to pay off student loans?

Yes. You can use up to a $10,000 lifetime maximum perindividual from a 529 plan to pay down qualified federal or private studentloan principal and interest. This limit applies per beneficiary and can also beused for each of the primary beneficiary’s siblings.

How do scholarship withdrawals work for a 529 plan?

If the beneficiary receives a scholarship, the IRS waives the 10% penalty on non-qualified 529 withdrawals up to the exact dollar amount of the scholarship received. You will still owe ordinary income tax on the earnings portion of the withdrawal, but the principal is tax-free and the penalty is removed.
