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

How each account actually works

A Trump Account is a new federal savings account for kids. The program went live July 4, 2026. Every U.S.-citizen child born between 2025 and 2028 can get a $1,000 federal seed deposited for them. Families can add up to $5,000 a year combined. An employer can chip in up to $2,500, but that counts inside the same $5,000 cap. The seed does not count toward it.

The money must go into an S&P 500 or U.S.-equity index fund. You cannot pick other investments. Growth is tax-deferred, and your contributions are after-tax (non-deductible). The account stays locked until January 1 of the year the child turns 18. After that, it works like a traditional IRA, so withdrawals are taxed as ordinary income.

A custodial account (UTMA/UGMA) works differently. An adult custodian manages the money for a minor. The assets are irrevocably the child's from day one. You can invest in almost anything. There is no contribution cap, though gifts above the annual exclusion (~$19,000 in 2025) may trigger gift-tax rules. You can use the funds anytime, as long as it benefits the child.

Taxes: tax-deferred growth vs the kiddie tax

This is the biggest difference. A Trump Account grows tax-deferred. You pay no tax each year on gains. But when the child withdraws after 18, the money is taxed as ordinary income, just like a traditional IRA.

A custodial account is taxed each year under the kiddie tax. Per the IRS, a set amount of the child's unearned income is tax-free. The next slice is taxed at the child's low rate. Anything above the threshold is taxed at the parents' marginal rate. In 2025 the kiddie tax kicks in once unearned income tops $2,700.

So the Trump Account defers all tax until withdrawal. The custodial account can create a small tax bill every year if it earns a lot. For a heavily funded custodial account, that yearly drag adds up. For a small one, the kiddie tax rarely bites.

Control, flexibility, and the FAFSA trap

The real trade is control and flexibility versus a free head start. A custodial account lets you invest in anything and spend on the child anytime — braces, a laptop, summer camp, a first car. Control transfers to the child at the age of majority, which ranges from 18 to 25 depending on your state and whether it is UTMA or UGMA.

A Trump Account is far more rigid. It is index-only, locked until 18, and taxed like an IRA. In exchange, you get the free $1,000 and simple, hands-off compounding.

Here is the non-obvious catch: on the FAFSA, a custodial account is the student's asset. Federal Student Aid assesses student assets at 20% — a much bigger aid hit than parental assets. A Trump Account gets lighter, retirement-style treatment. If college aid matters, that gap can outweigh the custodial account's flexibility. See how the numbers play out in are Trump Accounts worth it.

Which should you choose (or use both)?

Pick a Trump Account if your child qualifies for the free seed and you want a simple, long-term account you won't touch before 18. Our Trump Account calculator shows the payoff. The $1,000 seed alone at 7% grows to about $3,513 by age 18. Add $200 a month and it reaches roughly $89,657. Max the $5,000 a year and it hits about $182,980.

Pick a custodial account if you want investment freedom, no contribution cap, or money you can spend on the child before 18. It is also the better fit if you plan to invest in individual stocks or funds the Trump Account bans.

Many families use both. Grab the free Trump seed for the locked, tax-deferred bucket. Use a custodial account for goals before 18. If your child has a job, a custodial Roth IRA is a third option — but it requires the child to have earned income.
