The average four-year private college now costs over $250,000. Public in-state runs about $115,000. Two accounts dominate the college-savings conversation: the 529 plan, purpose-built for education, and the Roth IRA, designed for retirement but flexible enough to fund tuition. The right answer for most families is not one or the other, but both, in a specific ratio.

Key takeaways

• 529 plans offer tax-free growth and qualified withdrawals for education, plus a state income tax deduction in 34 states.
• Roth IRA contributions can be withdrawn any time tax- and penalty-free; earnings can be withdrawn penalty-free for qualified education expenses but remain taxable if under 59½.
• The Secure 2.0 Act allows up to $35,000 of leftover 529 funds to be rolled into a Roth IRA in the beneficiary's name, removing the main risk of overfunding.
• 529 assets owned by a parent count as 5.64% in the FAFSA asset calculation; Roth IRA assets are not reported at all on the FAFSA.
• For most families, the hybrid play is: max the state-deductible 529 contribution, then route additional savings into a Roth IRA for flexibility.

The two accounts at a glance

How the 529 plan actually works

A 529 is a state-sponsored investment account where contributions grow tax-free and withdrawals are tax-free if used for qualified education expenses. Each state runs its own plan, but residents can use any state's plan. The investment menu is usually a set of age-based portfolios that automatically shift from stocks to bonds as the beneficiary approaches college age, plus a handful of static index options.

State tax deduction is the biggest immediate benefit

Thirty-four states plus DC offer either a deduction or a credit for 529 contributions. The amount varies widely:

Most deduction states require residents to use that state's plan. Pennsylvania, Arizona, Kansas, Maine, Minnesota, Missouri, Montana, and Ohio allow the deduction on any state's plan.

What counts as a qualified withdrawal

• College tuition, fees, books, supplies, required equipment.
• Room and board for at-least-half-time students (up to the school's published cost of attendance allowance).
• K–12 tuition up to $10,000 per year per beneficiary.
• Apprenticeship program costs.
• Up to $10,000 lifetime in student loan repayments per beneficiary, plus $10,000 for each sibling.

How the Roth IRA fills the gap

A Roth IRA was built for retirement, but its rules make it a quietly excellent college backup. Contributions can be withdrawn at any age, for any reason, with no tax and no penalty — because the money was already taxed on the way in. Earnings can be withdrawn penalty-free for qualified education expenses at any age, although the earnings portion is still subject to income tax if the owner is under 59½.

What that means in practice

A parent who has contributed $7,000 per year to a Roth for ten years has $70,000 of contributions plus whatever earnings have accumulated. That $70,000 can come out tax-free and penalty-free to pay tuition, whether or not it is technically a qualified expense. If the parent does not need to use it for college — because a scholarship arrived, or the child chose a cheaper school — the money stays in the Roth and continues to compound tax-free for retirement.

The Secure 2.0 game-changer: $35,000 lifetime 529-to-Roth

Starting in 2024, the Secure 2.0 Act allows up to $35,000 of leftover 529 funds to be rolled over into a Roth IRA in the beneficiary's name. The rules:

• The 529 must have been open for at least 15 years.
• Contributions made in the past 5 years (and earnings on them) are not eligible.
• The Roth IRA must be in the name of the 529 beneficiary, not the account owner.
• Annual rollover is capped at the IRA contribution limit ($7,000 in 2026), counted against the beneficiary's total IRA contribution that year.
• The beneficiary must have earned income equal to or greater than the rollover amount.
• Lifetime cap is $35,000 per beneficiary.

This removes the historic risk of overfunding a 529. A child who receives a full scholarship, or who skips college entirely, can roll up to $35,000 into a Roth IRA as a giant head start on retirement savings.

Editor's pick: which 529 to open

Two plans dominate the no-residency-required rankings. Utah's my529 uses Vanguard and DFA funds with all-in expense ratios as low as 0.10% and is widely considered the highest-quality plan in the country. Nevada's Vanguard 529 is the simplest one-decision option: Vanguard Target Enrollment Portfolios at 0.12% all-in. Either is suitable if your state does not offer a deduction. If your state does offer a deduction, use your in-state plan to capture it — the deduction is usually worth more than the small expense ratio difference. A Roth IRA at Vanguard or Fidelity takes 10 minutes to open and pairs naturally with a 529 of either provider.

FAFSA treatment: the often-overlooked factor

Financial aid eligibility is calculated using the Student Aid Index (SAI). The key formulas treat the two accounts very differently.

529 plans

• Parent-owned 529s are reported as a parent asset on FAFSA, included at 5.64% of value.
• Grandparent-owned 529s used to count as student income (50% rate) when distributed; the FAFSA Simplification Act removed that question. As of the 2024–25 FAFSA, grandparent 529 distributions are no longer reported.

Roth IRAs

• Roth IRA balances are not reported as assets on the FAFSA. A parent with $200,000 in a Roth IRA is treated identically to a parent with $0.
• However, a Roth withdrawal does count as untaxed income on the FAFSA two years later, at up to 50%. This is the trap: pulling from a Roth to pay junior-year tuition can shrink senior-year aid.

The hybrid strategy most families should run

1. Open the in-state 529 if your state offers a tax deduction or credit. Contribute up to the deduction limit each year. This is essentially a 4% to 8% guaranteed annual return depending on your state tax rate.
2. If your state has no deduction, open Utah's my529 or Nevada's Vanguard 529 instead.
3. Once you have hit the state deduction cap, route additional college savings into a Roth IRA in your own name. The Roth is hidden from FAFSA and useful for any purpose.
4. Open a Roth IRA for the child as soon as they have earned income. Match what they earn, up to the annual limit. This funds future flexibility and can later receive a 529 rollover under the Secure 2.0 rules.
5. Withdraw from the 529 first during college, then from the Roth contributions only if needed. Avoid pulling Roth earnings before 59½ if possible.

A worked example

Married couple in Illinois, two kids ages 8 and 10, can deduct up to $20,000 per year of 529 contributions on Illinois taxes (combined, both kids). Their state marginal rate is 4.95%, so the deduction is worth $990 per year.

If one child gets a scholarship and the 529 is overfunded, up to $35,000 per child can roll into their Roth IRAs once they have earned income.

What about prepaid tuition plans?

Some states offer prepaid 529 plans that lock in today's tuition rates at in-state public colleges. Florida, Texas, and a handful of others run these. They work for families certain their child will attend an in-state public university. For everyone else, the investment-based 529 is more flexible and historically has had better returns.

Common mistakes

• Front-loading too aggressively. Putting $80,000 into a 529 at birth using the 5-year gift-tax election is great if everything goes to plan, but it removes flexibility. A blend of 529 and Roth keeps options open.
• Using a high-fee state 529. Some states' plans charge 0.5% to 1% all-in. If your state offers a deduction worth less than the fee drag, use Utah or Nevada instead.
• Withdrawing Roth earnings for college without checking the tax cost. Earnings are taxable as ordinary income if the owner is under 59½, even when the 10% penalty is waived for education.
• Forgetting the 15-year rule for Secure 2.0 rollovers. Open the 529 early, even with a small contribution, to start the clock.

FAQ

Is a 529 or a Roth IRA better for college?

A 529 wins on tax efficiency for actual college costs, especially in states with a deduction. A Roth IRA wins on flexibility because the money can be used for anything if college plans change. Most families should fund both, prioritizing the 529 up to the state tax deduction limit and then routing additional dollars to a Roth.

Can I roll a 529 into a Roth IRA?

Yes, up to $35,000 lifetime per beneficiary under the Secure 2.0 Act, provided the 529 has been open at least 15 years and the contributions are at least 5 years old. The annual rollover is capped at the IRA contribution limit and requires the beneficiary to have earned income.

Does a 529 hurt financial aid?

Only mildly. A parent-owned 529 is reported as a parent asset on the FAFSA at 5.64%. A $100,000 529 reduces aid eligibility by roughly $5,640. Grandparent-owned 529s no longer hurt aid at all under the simplified FAFSA.

What if my child does not go to college?

You have several options. Change the beneficiary to a different family member (sibling, cousin, even yourself). Use up to $10,000 for K–12 tuition. Use up to $10,000 to pay student loans. Roll up to $35,000 into the beneficiary's Roth IRA. Or take a non-qualified withdrawal and pay tax plus a 10% penalty on the earnings portion only.

Which 529 plan is the best?

Utah's my529 and Nevada's Vanguard 529 routinely top the independent rankings for low fees and high-quality investments. If your state offers a tax deduction tied to using its own plan, take the deduction unless the plan's fees are very high.

Can grandparents open a 529?

Yes, and as of the 2024–25 FAFSA, grandparent-owned 529s no longer affect financial aid. This makes grandparent 529s significantly more attractive than they were a few years ago.

How much can I contribute to a 529 per year?

There is no formal annual limit, but contributions above the federal gift tax exclusion ($19,000 in 2026 per donor per beneficiary) count against the lifetime gift tax exemption. A 5-year election allows front-loading $95,000 at once per donor.

Can I use a 529 for graduate school?

Yes. Qualified education expenses include accredited graduate and professional school programs.

What is the income limit for a Roth IRA?

For 2026, the Roth IRA contribution phases out between $150,000 and $165,000 of MAGI for single filers and between $236,000 and $246,000 for married filing jointly. Higher earners can use the backdoor Roth strategy.

Should I contribute to a 529 for myself?

Yes, if you plan to take graduate classes or simply want a place to compound tax-free with the option to change the beneficiary to a future child or grandchild. You can be both the account owner and the beneficiary.

Bottom line

Stop framing this as 529 versus Roth IRA. Use the 529 to capture your state tax deduction and tax-free growth on dollars certain to fund college. Use a Roth IRA for the rest, because flexibility has real value and the Roth disappears from the FAFSA. The Secure 2.0 Act's $35,000 rollover turns leftover 529 money into a retirement head start, removing the historic downside. The two accounts are partners, not alternatives.
