The Kids' Account Stack: 529s, Custodial Roths, UTMAs, and Trump Accounts

The 529 Plan: The Education Workhorse

A 529 plan is a state-sponsored investment account for education costs. Contributions go in after tax, growth is tax-deferred, and withdrawals are tax-free when used for qualified education expenses such as tuition.

Contributions count as gifts, and the annual gift tax exclusion is $19,000 per recipient per giver in 2026, or $38,000 for a married couple splitting gifts, before any gift tax paperwork enters the picture. Grandparents can contribute to the same child's plan under their own exclusions.

The old fear, that unused 529 money gets trapped, has softened. Since 2024, up to $35,000 of leftover 529 funds can roll into the beneficiary's Roth IRA over time. The conditions are real: the account must be at least 15 years old, contributions from the last 5 years cannot move, each year's rollover is capped at that year's Roth IRA limit, $7,500 in 2026, and the child needs earned income to match. The IRS has not yet settled whether changing the 529 beneficiary restarts the 15-year clock, so treat that question as open.

The Custodial Roth IRA: The Best Deal With a Catch

A custodial Roth IRA is a retirement account an adult opens and manages for a minor. Contributions go in after tax, and qualified withdrawals in retirement are tax-free, which makes decades of compounding for a teenager unusually valuable.

The catch is the entry requirement. The child must have real earned income, wages from a job or legitimate self-employment, and the contribution is limited to the lesser of that income or the annual limit, $7,500 in 2026. Allowance does not count.

When a teenager does have a summer job, this account usually deserves the first dollars. A parent can even gift the contribution amount while the child keeps their paycheck, as long as the contribution does not exceed what the child actually earned.

The UTMA: Flexible Money, Fixed Handoff

A UTMA account, named for the Uniform Transfers to Minors Act, is a custodial investment account holding money that already belongs to the child. There are no contribution limits and no restrictions on what the money is eventually used for.

Two features deserve clear eyes. First, every contribution is an irrevocable gift; you cannot take it back or redirect it to a sibling. Second, the child gains full control at the age of majority or the transfer age set by state law, often 18 to 21 depending on the state, whether or not they are ready for it.

UTMA assets also count as the student's own in financial aid formulas, which typically reduces aid eligibility more than the same dollars held in a parent-owned 529.

Trump Accounts: The New Arrival

Trump Accounts, created under Internal Revenue Code section 530A, open for contributions on July 4, 2026. The account is a tax-deferred investment account for children under 18 that works roughly like a traditional IRA for kids who have no earned income, with funds generally locked until age 18.

Children who are U.S. citizens with a Social Security number and born between January 1, 2025 and December 31, 2028 qualify for a one-time $1,000 federal pilot-program deposit, which parents claim by election on IRS Form 4547. That seed money is the clearest reason to open one if your child qualifies.

Contributions are after-tax and not deductible, capped at $5,000 per year per child across all contributors combined, with the cap indexed for inflation after 2027. An employer can contribute up to $2,500 per year, excluded from the employee's income but counted inside the $5,000 cap. The $1,000 federal seed does not count against the cap.

For a qualifying child, the $1,000 federal seed is the rare account-opening decision with no real downside.

Which Account First?

The right order depends on your family, but a common framework runs like this:

• Claim free money first: the $1,000 Trump Account seed for a qualifying child, and any employer contribution offered.
• Fund a custodial Roth IRA up to the child's earned income once they have a real job, since tax-free growth usually beats tax-deferred.
• Direct education savings to a 529, sized to realistic school costs, knowing the Roth rollover path softens the overfunding risk.
• Use a UTMA last, for gifts meant to be unrestricted, and only if you accept the fixed handoff at the state's transfer age.
