Why a 529 Plan Is the Best Way to Invest for Your Child’s Future

Most parents want their kids to start adult life without the crushing weight of student debt. A 529 plan lets you fund your child’s education while potentially setting them up to become retirement millionaires before age 60, all through one powerful account.

Here’s how this strategy works and why 529 plans beat other options like custodial brokerages.

What Makes a 529 Plan Different

A 529 plan is a tax-advantaged education savings account that grows your money without federal taxes on earnings when used for qualified education expenses. You contribute after-tax dollars, those dollars grow tax-free, and withdrawals for education come out tax-free.

College costs keep climbing. For the 2024-2025 school year, average published tuition, fees, room, and board at a public four-year school for out-of-state students hit $44,090. Private nonprofit four-year schools cost $58,600. That’s a lot of potential debt your kid won’t have to carry if you save strategically.

Beyond just paying for college, 529 plans now offer something game-changing: the ability to roll over unused funds to a Roth IRA in your child’s name.

The 529 Plan to Roth IRA Rollover Changes Everything

Starting in 2024, the SECURE 2.0 Act allows you to roll over unused 529 funds to a Roth IRA in the beneficiary’s name. This is tax-free and penalty-free up to a $35,000 lifetime limit.

The requirements are straightforward. The 529 account must have been open for at least 15 years. Annual Roth IRA contribution limits apply, which is $7,000 for 2025. Any contributions made in the last five years aren’t eligible for rollover, but earnings on older contributions are.

This means leftover 529 money doesn’t go to waste. Instead, it jumpstarts your child’s retirement savings with decades of tax-advantaged compound growth ahead.

How to Overload a 529 Plan for Maximum Benefit

Here’s the strategy: contribute heavily to your child’s 529 plan early, let compound growth do its work over 18+ years, pay for college, then roll remaining funds to a Roth IRA.

You can contribute up to $19,000 per year per beneficiary without gift tax reporting requirements in 2025. Married couples can contribute $38,000 combined. But there’s an even better option called superfunding.

Superfunding lets you contribute five years’ worth at once. That’s $95,000 for an individual or $190,000 for married couples in 2025. This front-loads the account for maximum compound growth over time.

Most states set aggregate contribution limits between $235,000 and $600,000 per beneficiary. You won’t hit these limits unless you’re funding multiple degrees or significantly overfunding for the rollover strategy.

The Math Behind Creating Retirement Millionaires

Let’s say you superfund a 529 with $95,000 when your child is born. Over 18 years at a 7% average annual return, that grows to roughly $307,000. You spend $240,000 on four years of college. You have $67,000 left over.

You roll $35,000 of that into your child’s Roth IRA between ages 22 and 27 following annual contribution limits. Your child never adds another dollar. That $35,000 compounds at 7% for 33 more years until age 60.

The result: approximately $350,000 in their Roth IRA at retirement, entirely tax-free. And that’s without your child contributing a single dollar beyond what you gifted.

Now teach your child to max out their Roth IRA contributions each year once they start earning income. The $7,000 annual limit for 2025 means they could contribute consistently throughout their career. Combined with your $35,000 head start, they’re set up to become actual millionaires by traditional retirement age.

Why the 529 Plan Beats Custodial Brokerages

Custodial accounts like UTMA/UGMA seem appealing, but they have serious drawbacks that make 529 plans the better choice.

Control matters: UTMA/UGMA accounts legally transfer to your child at age 18 or 21 depending on your state. At that point, the money is theirs to do whatever they want with it. Most 18-year-olds aren’t equipped to handle a six-figure brokerage account responsibly.

With a 529 plan, you maintain control as the account owner. If your child makes poor choices or doesn’t pursue education, you can change the beneficiary to another family member or even yourself. The money stays protected.

Tax treatment makes a difference: Custodial accounts get taxed annually on earnings and gains. This creates a tax drag that reduces long-term growth. 529 plans grow completely tax-free when used for qualified expenses.

Financial aid treatment varies: UTMA/UGMA accounts are considered student assets for FAFSA purposes, which reduces financial aid eligibility more than parent-owned 529 plans. This can cost you thousands in lost aid.

Flexibility for multiple children: You can’t transfer custodial account funds from one child to another. Each account is permanently tied to one beneficiary. 529 plans let you change beneficiaries among family members without penalty, giving you more strategic options.

What Counts as a Qualified Education Expense

529 plans cover more than just college tuition. Qualified expenses include:

  • College tuition and fees
  • Room and board for students enrolled at least half-time
  • Books, supplies, and equipment required for enrollment
  • K-12 tuition up to $10,000 per year
  • Apprenticeship programs registered with the Department of Labor
  • Student loan repayment up to $10,000 lifetime per beneficiary

This flexibility means your child can use the funds for trade school, vocational training, or other education paths beyond traditional four-year colleges.

State Tax Benefits Add Extra Savings

Many states offer income tax deductions or credits for 529 contributions. The amount varies by state, typically ranging from a few thousand to unlimited deductions.

Seven states allow deductions regardless of which state’s plan you use: Arizona, Arkansas, Kansas, Minnesota, Missouri, Montana, and Pennsylvania. Most other states require you to use their home state plan to get the tax benefit.

These state tax benefits are annual, not lifetime, so they reward consistent contributions over time rather than lump-sum superfunding. You can structure your contribution strategy to maximize both state tax benefits and long-term growth.

How to Implement This Strategy

Start by opening a 529 plan as soon as possible after your child is born. The earlier you start, the more time compound growth has to work in your favor.

If you have the funds available, consider superfunding with five years’ worth of contributions upfront. This gives your money maximum time in the market. If superfunding isn’t realistic, contribute as much as you can consistently each month or year.

Choose low-cost index fund investment options within your 529 plan. High fees eat into returns over 18+ years. Target-date funds that automatically adjust as your child approaches college age can simplify the process.

When your child reaches college age, use 529 funds for qualified expenses first. Save taxable accounts for last since those don’t have the same tax benefits.

After college, if you have money left over, wait until the 529 has been open for 15 years and then begin rolling funds to a Roth IRA following annual contribution limits.

Throughout all of this, teach your child about money management, investing, and the power of compound growth. The financial head start you’re giving them only works if they develop good money habits themselves.

The Bottom Line

A 529 plan is the most powerful tool available for funding your child’s education while avoiding student debt. The ability to roll unused funds to a Roth IRA transforms these accounts from education-only savings into wealth-building machines.

By overloading a 529 plan early, you can pay for college and give your child a retirement foundation that could be worth hundreds of thousands of dollars by age 60, even without additional contributions. This beats the alternative of custodial accounts that offer less control, worse tax treatment, and no strategic flexibility.

The prepaid lifestyle means saving for what matters, then making strategic choices with that saved money. A 529 plan is one of the smartest strategic choices you can make for your child’s financial future.
