529 Plans and the New Rollover Rules: College Saving, Reconsidered

For years, 529 plans were golden until they weren't: save for college tax-free, but if your kid doesn't go, you're stuck with penalties and taxes on the earnings. Now that cage door just opened.

In 2024, the rules changed. Starting in 2026, leftover funds in a 529 plan can roll into a Roth IRA—without the traditional income limits—if certain conditions are met. This single change transforms how families should think about education savings. It removes one of the biggest objections to 529s: "What if they don't go to college?" Now there's an answer that doesn't involve paying Uncle Sam.

This doesn't mean 529 plans are suddenly a no-brainer for everyone. It means they're worth reconsidering if you've dismissed them before, and worth understanding if you're trying to design a savings strategy now.

How 529 Plans Work

A 529 plan is a tax-advantaged investment account specifically designed for education expenses. Here's the basic structure:

• You contribute after-tax money. There's no federal income tax deduction (though some states offer one). You're using money you've already paid taxes on.
• The money grows tax-free. Dividends, interest, capital gains—all compound without annual tax drag. This is the magic feature.
• Withdrawals for qualified education expenses are tax-free. Tuition, room and board, books, required equipment, even up to $35,000 of student loan repayment—all come out tax-free if used for these approved purposes.
• If you withdraw for non-qualified expenses, earnings are taxed plus a 10% penalty. This was the nightmare scenario: save diligently, then get hit with taxes and penalties if the plan doesn't go as expected.

The account can be opened in any state, regardless of where you live. Your child can attend school anywhere. And importantly, you (the parent) retain control—your child can't access the money without permission. This is different from UTMA/UGMA accounts where the child controls the funds at age of majority.

The New Rollover Rules

Starting in 2026, you can roll unused 529 funds into a Roth IRA under these conditions:

• The 529 account must have been open for at least 15 years.
• The rollover is limited to the annual Roth contribution limit (currently $7,000 for 2024, indexed annually).
• You can roll over only earnings, not contributions. The contributions stay in the 529 (they're post-tax anyway).
• The beneficiary's name must match between the 529 and the Roth IRA—you can't transfer to someone else's retirement account.
• The child can also use leftover funds for apprenticeships and certain military service benefits.
• There's a $35,000 aggregate lifetime limit on 529-to-Roth rollovers.

This is a genuine game-changer. Roth IRAs are one of the most powerful retirement vehicles available: you contribute after-tax money, it grows tax-free forever, and qualified withdrawals in retirement are completely tax-free. The ability to feed a Roth IRA via a 529 means unused education savings becomes genuine wealth-building.

Why This Matters

The biggest objection to 529 plans used to be: "What if my kid doesn't go to college, or gets a scholarship, or decides trade school is better?" The penalty structure meant you couldn't just walk away—you'd lose some of your own growth to taxes and the 10% penalty.

Now that scenario has a solution. If your child gets a full scholarship, the unused money can roll into a Roth. If they decide not to pursue higher education at all, the money doesn't evaporate—it becomes retirement savings. If they go to a cheap state school and finish early, the extra sits in a Roth growing tax-free for forty years.

This removes friction from the decision to open a 529. You're no longer betting everything on a college outcome.

How Much Should You Save?

That depends on three variables: how much college might cost, how much you think you can afford to save, and your comfort with uncertainty.

College cost reality: Public in-state universities run roughly $25,000–$35,000 per year (tuition + room and board). Private universities run $60,000–$80,000+. A four-year degree at a public in-state school might cost $100,000–$140,000 by the time your child reaches college age (accounting for inflation). A private university could easily exceed $250,000.

These are approximate and will vary by state and institution, but they give you a ballpark.

Savings options:

• Aggressive saver: If you start early (child is newborn), saving $500/month for 18 years gives you around $108,000–$150,000 depending on returns. This covers public in-state almost completely, with rollover buffer.
• Moderate saver: $200/month for 18 years gives you around $44,000–$60,000. This covers roughly half of public in-state, enough to meaningfully reduce student loans.
• Conservative saver: $50/month for 18 years gives you around $11,000–$15,000. This is enough to cover books and supplies, and provides a meaningful head start.

The specific numbers depend on investment returns, but the pattern holds: even modest contributions compound significantly over 18 years.

529 vs. Other Options

How do 529s compare to other ways to save for education?

529 vs. Roth IRA (for education): A Roth IRA can be used for education without the early withdrawal penalty if you haven't taken other Roth distributions. But a 529 grows tax-free specifically for education. 529s also don't count against federal financial aid the same way a Roth does. The new rollover feature means they're now complementary—use the 529 first, roll unused funds into the Roth.

529 vs. 401(k): 401(k) plans at work can now receive up to $35,000 in education debt repayments, but this only helps after graduation. 529s are specifically for current education costs. They serve different purposes.

529 vs. taxable brokerage account: A 529 grows tax-free; a taxable brokerage account has annual capital gains taxes. Over 18 years, this tax drag can cost you 10–15% of your final amount. 529s win on taxes. The downside: less flexibility (you're locked into education-related uses without penalty, though the rollover rule now changes that).

529 vs. savings account: A high-yield savings account is liquid and guaranteed, but earns 4–5% annually. A 529 invested in index funds historically earns 7–10% annually (with some volatility). Over 18 years, that difference compounds to substantially more money. You trade guaranteed safety for likely higher returns.

529s are strongest when you expect to need the money for education and can tolerate moderate market volatility. The new rollover rule weakens the "what if we don't use it" objection, making them attractive even if college isn't certain.

Investment Strategy

A 529 can hold any securities your provider allows. Most popular providers offer age-based portfolios that automatically shift from stocks to bonds as your child approaches college age.

Age-based approach (simplest): When your child is born, your account holds 90% stocks and 10% bonds. Each year, it automatically rebalances toward more conservative allocations. By age 17, it's mostly bonds. This is set-it-and-forget-it.

Custom approach: If you're comfortable managing it yourself, you can pick your own allocation. Common strategies: 100% stock index funds while the child is young (leveraging time to recover from volatility), shifting to 50/50 around age 10, then to conservative around age 15.

Important note: The money you contribute (your basis) is never at risk of penalty—only earnings. If you invest $50,000 and it grows to $70,000, only the $20,000 in earnings get hit with tax and penalty if withdrawn for non-qualified expenses. Your $50,000 comes back tax-free no matter what.

FAQ

Does a 529 hurt my child's financial aid eligibility?

Yes, but it's complicated. A 529 in the parent's name affects FAFSA eligibility less than a 529 in the child's name (5% vs. 20% of assets expected to fund education). However, it does reduce need-based aid. The trade-off: 529s grow tax-free, and the new rollover rules mean unused funds don't go to waste. For many families, the tax savings exceed the aid reduction. Run the numbers for your situation.

What if my child gets a full scholarship?

Previously, this was a worst-case scenario. Now you have options: (1) use the funds for room and board, books, or other qualifying expenses; (2) roll unused funds into a Roth IRA for your child's retirement; (3) change the beneficiary to a sibling. The penalty scenario is much less likely to bite you.

Can I change the beneficiary if my first child doesn't go to college?

Yes, without tax or penalty. If you opened a 529 for your first child and later have another child, you can change the beneficiary to the sibling, and the money continues growing tax-free. This is especially powerful in multi-child families.

Which state's 529 should I use?

You can use any state's plan regardless of where you live. Some states offer income tax deductions for contributions to their own 529 (check your state's rules). Otherwise, compare plans on investment options, fees, and customer service. Many investors use Vanguard's or Fidelity's plans for low fees and broad fund selection.

Is the $35,000 aggregate rollover limit per child or per parent?

It's per beneficiary (per child). Each child can have up to $35,000 rolled from their 529 into their own Roth IRA over their lifetime. Parents don't share this limit across children.
