529 Plan vs. Custodial Account (UTMA/UGMA): Which Is Better for Your Child?

Short answer: In the 529 vs. custodial account choice, a 529 plan is usually the better fit when the money is meant for education. Its earnings aren't subject to federal income tax when used for qualified education expenses, and a parent-owned 529 counts as a parent asset on the FAFSA. A UTMA or UGMA custodial account is more flexible, since the money can be used for anything that benefits the child. But the gift is typically irrevocable, the child takes control at 18 or 21 depending on the state, and it counts as the student's asset for financial aid.

Both accounts let you set money aside for a child. They work very differently once you look at taxes, who's in control and what the money can pay for. This guide compares them side by side, using rules from the SEC, IRS, the OCC and the U.S. Department of Education.

How Does a 529 Plan Work?

Investor.gov, the SEC's investor education site, says there are two types of 529 plans: education savings plans and prepaid tuition plans. The person who opens the account is the account holder, and the person it's opened for is the beneficiary.

The tax benefit is the main draw. Investor.gov says earnings in a 529 account are not subject to federal income tax, and in many cases state income tax, when you use the money for qualified education expenses. The IRS says contributions to a 529 (which it calls a qualified tuition program, or QTP) aren't deductible on your federal return, though Investor.gov notes that many states offer tax benefits for contributions.

Qualified uses go beyond college tuition. Investor.gov lists:

• K–12 tuition: up to $20,000 per year per beneficiary for tuition and certain expenses at public, private or religious elementary and secondary schools. IRS Topic 313 notes the limit was $10,000 before the end of 2025.
• Student loans: qualified education loan repayments up to $10,000 total per beneficiary.
• Apprenticeships: the IRS includes fees, books, supplies and equipment required for participation in an apprenticeship program.

If you withdraw money for something else, Investor.gov says the earnings will be subject to state and federal income taxes and an additional 10% federal tax penalty.

Investment risk applies too. Investor.gov says state governments do not guarantee investments in education savings plans, and you can lose money. Fees, such as enrollment, annual maintenance and program management fees, also lower your returns. Our guide to mutual funds vs. index funds explains how fund costs add up.

What Is a UTMA Account (or UGMA Account)?

A Uniform Gifts to Minors Act (UGMA) or Uniform Transfers to Minors Act (UTMA) account is an account into which property is set aside for a minor's benefit, according to HelpWithMyBank.gov, a site run by the Office of the Comptroller of the Currency (OCC). Which one you use depends on the law of the state where the account is opened.

Three features matter most:

1. The gift is permanent. Transfers to a UGMA or UTMA account are typically irrevocable and belong to the child in whose name the account is registered.
2. The custodian controls it for now. The account is controlled by the custodian until the child reaches a certain age, which varies by state (usually 18 or 21).
3. State rules vary. The rules governing these accounts differ from state to state, so check yours.

FINRA adds that UGMA and UTMA accounts have no withdrawal penalties, contribution limits or use restrictions, but the funds must be used solely for the benefit of the minor. The assets transfer to the child at the age of majority, which differs by state, and can then be used for any purpose.

How Are Custodial Accounts Taxed?

A custodial account doesn't get the 529's education tax break. Its investment income is the child's unearned income, which is where the kiddie tax comes in.

IRS Topic 553, which links to the 2025 versions of Forms 8615 and 8814, says the kiddie tax rules apply if a child's interest, dividends and other unearned income total more than $2,700 and the child meets one of these age tests at the end of the tax year:

• Under age 18
• Age 18 and didn't have earned income that was more than half of the child's support
• A full-time student at least age 19 and under age 24 who didn't have earned income that was more than half of the child's support

The IRS also describes an option to report a child's income on the parent's return using Form 8814, which is available only in certain cases, including when the child's gross income was less than $13,500. These thresholds can change each year, so check IRS Topic 553 and the current form instructions for your tax year.

Which Is Better for Financial Aid?

The U.S. Department of Education's 2026–27 FAFSA guidance treats the two accounts differently:

• 529 plans. For a dependent student, a 529 college savings plan designated for the student is reported as a parent investment. Its value is the current balance of the account. If the student is the beneficiary but not the owner, the value is not reported as a student asset.
• UTMA/UGMA accounts. These count as the minor's asset on the FAFSA form, not the asset of the custodian.

Investor.gov adds that investing in a 529 plan will generally affect a student's eligibility for need-based financial aid.

What If Your Child Doesn't Go to College?

This is where the two accounts split the most.

With a 529, you have a few paths:

• Change the beneficiary. IRS Publication 970 says there are no income tax consequences if the beneficiary is changed to a member of the beneficiary's family.
• Roll some into a Roth IRA. Investor.gov says you can roll 529 money into a Roth IRA for the same beneficiary. The total rollover is limited to $35,000, the 529 account must have been open at least 15 years, and the money you roll over must have been in the account at least five years. The IRS adds that each rollover is subject to the Roth IRA annual contribution limit.
• Take a non-qualified withdrawal. You'll owe income tax and the additional 10% federal tax on the earnings.

With a custodial account, the money already belongs to your child. When they reach the age set by your state, they can use it for anything.

Can You Have Both?

Yes. The two accounts aren't either-or: a family can save for education in a 529 and for other goals in a custodial account. Before you put money into either one, make sure your own foundation is solid. An emergency fund covers surprise bills, and your own retirement savings matter too.

The Bottom Line

If the goal is education, a 529 plan usually offers more. Earnings aren't subject to federal income tax when used for qualified expenses, and a parent-owned 529 counts as a parent asset on the FAFSA. A UTMA or UGMA custodial account trades those advantages for flexibility: the money can pay for anything that benefits the child, but the gift is permanent and your child takes control at 18 or 21, depending on your state.

Frequently asked questions

What is the difference between a 529 plan and a custodial account?

A 529 plan is an education savings or prepaid tuition plan sponsored by a state, state agency or educational institution, with federal tax benefits for qualified education expenses. A UTMA or UGMA custodial account holds property for a minor's benefit. The money belongs to the child and can be used for things other than school, but it doesn't get the 529's education tax break.

At what age does a child get control of a UTMA or UGMA account?

It depends on your state. HelpWithMyBank.gov, run by the OCC, says the custodian controls the account until the child reaches an age that varies by state, usually 18 or 21.

Can I move money from a custodial account back to myself?

Generally not. HelpWithMyBank.gov says transfers to a UGMA or UTMA account are typically irrevocable and belong to the child in whose name the account is registered.

What happens if my child doesn't use the 529 for college?

You have options. IRS Publication 970 says changing the beneficiary to a member of the beneficiary's family has no income tax consequences, and Investor.gov says a 529 that has been open at least 15 years can roll up to $35,000 over a lifetime into a Roth IRA for the same beneficiary, subject to the Roth IRA annual limit. Non-qualified withdrawals face income tax and an additional 10% federal tax on earnings.

Which is better for financial aid, a 529 or a UTMA?

Under the 2026–27 FAFSA guidance, a 529 owned by a parent for a dependent student is reported as a parent investment, while a UTMA or UGMA account counts as the student's asset. Investor.gov notes that a 529 plan will generally affect a student's eligibility for need-based aid.
