UTMA vs. 529: Ownership, the Kiddie Tax, and Financial Aid for Physician Parents

A grandparent mails a check for your daughter's birthday with a note that says "for her future." A relative asks which account to send money to. Or you open an old statement and find a custodial account you set up years ago, back when you were still in training and a 529 felt like something for later. Each of these moments raises the same question: is this money better held in a UTMA or a 529?

The two accounts look similar on the surface. Both hold money for a child, and both can be invested. Underneath, they work differently. The biggest differences we'll cover are: who owns the account, how the earnings get taxed (including the kiddie tax), and how each account shows up when your child applies for federal financial aid. If you've already read our comparison of 529 plans, Roth IRAs, and taxable brokerage accounts for college savings, think of this article as the companion piece on the account that often gets left out of that conversation: the custodial account in your child's name.

Below we'll walk through how each account works, where the trade-offs show up for a physician household, when a UTMA can still fit, and what to think about if you're considering moving UTMA money into a 529.

What a UTMA and a 529 Actually Are

A UTMA account is a custodial account held for a minor. You, or another adult, act as the custodian, and the child is the legal owner. That ownership is the single most important feature of the account, because it affects how the money is treated for taxes and for financial aid.

A 529 plan is an education savings account named after the section of the tax code that created it (the tax code calls it a qualified tuition program). In a typical parent-owned 529, you're the account owner and your child is the beneficiary. According to IRS Publication 970, earnings in a 529 aren't taxed when they're withdrawn for qualified education expenses, which include tuition and fees, books, supplies, and required equipment, along with certain K-12 tuition and postsecondary credentialing costs. If you're still sorting out the K-12 side, our article on using a 529 for private K-12 tuition covers those rules in more detail.

That one structural difference, the child owning the UTMA while you own the 529, drives much of what follows.

Ownership: Who the Money Belongs To

With a UTMA, the child is the owner of the account and the custodian manages it on the child's behalf. Because the account belongs to your child, it isn't a good place for money you may want to redirect later, so it's worth thinking this through before you fund it.

A parent-owned 529 is structured differently, since you're the owner and your child is the beneficiary. The tax code allows the designated beneficiary to be changed to a member of the beneficiary's family, which gives a 529 a kind of flexibility the child-owned UTMA doesn't have. That flexibility is also why leftover 529 money is a planning question of its own.

How the Kiddie Tax Works on UTMA Earnings

UTMA earnings are generally the child's income, since the child owns the account. That can matter because of what's commonly called the kiddie tax, which limits how much of a child's investment income is taxed at the child's own rate.

Here's how it's structured. The IRS explains the kiddie tax in Tax Topic 553: when a child's interest, dividends, and other unearned income exceed $2,700, it may be subject to the kiddie tax. IRS Revenue Procedure 2025-32 sets the 2026 amount used to reduce a child's net unearned income at $1,350. In plain terms, that looks like this:

• The first $1,350 of a child's unearned income generally isn't taxed, because it's covered by the dependent's standard deduction.
• The next $1,350 is taxed at the child's own rate.
• Anything above $2,700 is taxed at the parent's tax rate if the parent's rate is higher than the child's.

The kiddie tax doesn't stop at 18. It applies to children under 18 at the end of the year, to 18-year-olds whose earned income doesn't cover more than half their support, and to full-time students ages 19 through 23 in the same situation. So a UTMA that's still invested while your child is in college can keep generating income that may be taxed at your rate for years.

For a physician household, your marginal rate is likely to be higher than your child's, which means unearned income above the threshold may be taxed at your rate. There's also some paperwork. Under the Form 8615 instructions, the child may need to file a return with Form 8615, or, in some cases, you can elect to report the child's interest and dividend income on your own return. It's a small task, but it's one more thing to track during tax season.

By comparison, a qualified tuition program is exempt from tax under section 529 of the tax code, and earnings come out tax-free when used for qualified expenses. If money comes out for something that isn't a qualified expense, the earnings portion is generally taxable and may face an additional 10% tax, with some exceptions (such as when the beneficiary receives a scholarship), as Publication 970 describes.

How Each Account Shows Up on the FAFSA

Financial aid can feel like a long shot for a physician family, and our article on whether a physician income disqualifies your kids from college aid walks through what to expect. Still, it helps to know how each account is reported if aid does come into play.

The federal treatment is clear. The Federal Student Aid Handbook's guidance on filling out the FAFSA states that because the minor owns a UTMA or UGMA account, it counts as the student's asset, not the custodian's. A parent-owned 529 designated for a dependent student is reported as a parental asset.

The formula then treats the two differently. Under the Student Aid Index formula, a dependent student's net worth is multiplied by a 20% conversion rate to get the student's contribution from assets. Parental assets first get reduced by an asset protection allowance, then multiplied by a 12% conversion rate, and the result is then run through assessment rates that range from 22% to 47%.

UTMA vs. 529 Side by Side

Here's how the two accounts line up against each other:

When a UTMA Can Still Make Sense

None of this means a UTMA is a mistake. It's a different tool with a different job. Here are a few situations where custodial accounts tend to come up in planning conversations with physician families:

• Goals that aren't education. If college is already funded through 529s and you'd like to set money aside for something else, such as your child's first car or help with a first home, a 529 isn't built for those uses, since earnings withdrawn for non-qualified expenses may be taxed and face an additional 10% tax.
• Staying in the lower kiddie tax tiers. A modest UTMA that generates unearned income under the $2,700 threshold stays outside the kiddie tax. Some families keep custodial balances in that range deliberately, though the benefit is small at a physician income and the account may outgrow it.
• Teaching your kids about money. An account with your child's name on it can be a useful way to talk with a teenager about investing, saving, and the long view.
• Gifts from relatives who want the child to own it. Grandparents sometimes prefer to give directly to a grandchild. For reference, Revenue Procedure 2025-32 sets the 2026 annual gift tax exclusion at $19,000 per recipient, and how a relative's gift is structured is often a conversation between them and their own advisor.

The common thread is that a UTMA fits best when you're comfortable with your child owning the account, and when you've thought through how the balance may affect financial aid.

Moving UTMA Money Into a 529: What to Think About

Once you see the aid and ownership differences, a natural thought is to move the UTMA money into a 529. A few mechanics are worth understanding first.

Here are the mechanics that bear on the question:

• 529 contributions have to be cash. Section 529 provides that purchases or contributions to a qualified tuition program may only be made in cash, so any investments held in the UTMA would have to be sold first.
• Sales can have tax consequences. A sale of investments that have gained value may produce taxable income for the child, and the kiddie tax rules above may apply to it.
• The tax treatment of future earnings shifts. Once inside the 529, earnings are exempt from tax under section 529 and come out tax-free for qualified education expenses, instead of being reported as the child's income each year.

The trade-offs in this decision include the tax cost of selling appreciated investments now and whether the money is likely to be spent on education at all, since earnings from a 529 used for non-qualified expenses are generally taxable and may face an additional 10% tax.

This is a good point to bring in a CFP® professional or your tax professional, because the right sequence depends on the cost basis, the size of the account, and how many years remain before college.

How Physician Parents Typically Weigh the Two

When this comes up in planning conversations, the questions tend to look something like this:

• Is this money meant for education, or for your child's life more broadly?
• How comfortable are you with your child owning the account outright?
• Is need-based or institutional aid a realistic possibility for your family, now or if your circumstances change?
• Does your state offer a tax benefit for 529 contributions, and does it apply to the plan you'd use?
• If there's an existing UTMA, what's the cost basis, and what would selling it cost in taxes?

For families leaning toward the 529 side, the next question is often how much to put in and when. If you have the cash flow, front-loading contributions is one option, which we cover in our article on the 529 superfund strategy. Another approach is steady monthly contributions that fit around retirement savings, student loans, and everything else a physician paycheck is already doing.

It also doesn't have to be one or the other. Some households keep a 529 as the main education account and a smaller UTMA for non-education goals, with each account doing the job it was designed for. What matters is knowing why each account exists and how it fits with the rest of your plan.

Talking Through Your Family's Version of This

The UTMA vs. 529 decision usually doesn't feel urgent, which is why it can sit untouched for years. But the choice of account shapes who owns the money, how it's taxed, and how it's counted when your child applies for federal aid.

Questions like these come up often in our twenty-five years of working with physician families, usually as kids grow up and plans change. If you'd like to talk through how college savings fit with the rest of your family's goals, you can tell us a little about your family.
