Comparing Investment Accounts for Kids: 529 vs. UTMA vs. Roth IRA vs. 530A Trump Account

Parents saving for a child in 2026 have four main accounts to choose from: a 529 plan, a custodial account (UTMA or UGMA), a custodial Roth IRA, and the new Trump Account created under Section 530A of the tax code. All four can hold investments that grow for years. But each is built for a different job, and picking the wrong one can mean paying tax you didn’t need to pay, losing control of money you meant for college, or leaving free money unclaimed.

This guide compares them side by side on the four questions that matter most: how each account is taxed, what the money can be spent on, how much can go in, and when your child takes control. It’s the hub for our section on account types, part of The Ultimate Guide to Building a Generational Nest Egg for Your Child, and every section points to a deeper guide on the account it covers.

Meet the four accounts

Before comparing them, here’s what each account is in a sentence or two.

529 plan. A state-sponsored education savings account. You own it, your child is the beneficiary, and you invest through the plan’s menu of options, which often includes age-based portfolios that shift toward more conservative investments as college approaches, according to the SEC’s Investor.gov. The Complete Guide to 529 College Savings Plans covers it in depth.

UTMA or UGMA custodial account. A regular investment account held in your child’s name and managed by an adult custodian, usually a parent, until your child reaches a handoff age set by state law. The money belongs to your child from the moment it’s deposited. UTMA vs. UGMA: What’s the Difference? explains the two versions.

Custodial Roth IRA. A Roth IRA that a parent or other adult opens and manages for a minor with earned income, whether from a job or from self-employment such as babysitting or lawn care, Vanguard explains. It’s the same Roth IRA adults use, with a custodian in charge until your child comes of age. The Custodial Roth IRA has the details.

Trump Account (Section 530A). A new type of traditional IRA for children under 18, created by the 2025 law known as the One Big Beautiful Bill Act, which the IRS calls the Working Families Tax Cuts. Contributions couldn’t be made before July 4, 2026, according to IRS news release IR-2025-117. The account is owned by your child and run by an adult until your child reaches 18, and each child can have only one funded Trump Account, Fidelity explains. The 530A Trump Account Explained goes deeper.

529 vs. UTMA vs. Roth IRA vs. Trump Account at a glance

The table sums up how the four accounts compare on taxes, spending flexibility, contribution limits, and age of transfer, plus a few other differences worth knowing. The sections that follow explain each row and the rules behind it.

Swipe the table sideways to see all four accounts.

Federal rules for 2026. States set 529 tax breaks and account maximums, and the age a custodial account transfers. Several Trump Account rules are still being finalized.

Investment choices differ, too. A 529 plan limits you to the plan’s menu, and its age-based portfolios shift gradually toward safer investments as college approaches, the kind of de-risking described in Building a Target-Date Glide Path. Custodial Roth IRAs come with broad investment menus, Fidelity notes, as do custodial brokerage accounts. A Trump Account is the most restricted: until the end of the year your child turns 17, it can hold only mutual funds or exchange-traded funds that track an index of mostly U.S. stocks, such as the S&P 500, don’t use leverage, and charge annual fees of 0.1% or less, according to IRS news release IR-2026-96. Index Funds vs. Stock Picking for Minors explains why a simple index fund is a strong choice in any of these accounts.

Tax advantages compared

All four accounts get some kind of tax help, but the kind of help differs, and it decides how much of your child’s money ends up going to taxes.

529 plan: tax-free for education

Money in a 529 plan grows without yearly tax, and withdrawals are tax-free when they pay for qualified education expenses, Saving for College explains. Many families get a break going in, too: nearly 40 states offer a state income tax deduction or credit for 529 contributions, usually up to a yearly cap, and most require you to use your own state’s plan to claim it, according to Saving for College’s 2026 limits guide.

Custodial account: a small break, then the kiddie tax

A UTMA or UGMA account has no tax shelter of its own. Its investment income is your child’s income, taxed each year. In 2026, the first $1,350 of a child’s investment income is tax-free, the next $1,350 is taxed at the child’s rate, and income above $2,700 is generally taxed at the parents’ rate, under IRS Revenue Procedure 2025-32. Navigating the 2026 Kiddie Tax Thresholds shows how to keep that tax small.

Custodial Roth IRA: tax-free for life

Roth contributions go in after tax, but the growth is never taxed if withdrawals are qualified, which generally means your child is at least 59½ and the account has been open five years. Contributions themselves can come out at any time, tax- and penalty-free, Fidelity notes. The “after tax” part often costs a teen nothing. In 2026, a dependent’s standard deduction covers earned income up to $16,100, so a teen whose only income is $6,000 from a summer job owes no federal income tax on it, under Revenue Procedure 2025-32, though Social Security and Medicare taxes can still apply. That makes a Roth one of the few places where money can go in untaxed and come out untaxed. At a hypothetical 7% average annual return, $2,000 of summer-job pay invested at 16 could grow to about $39,257 by age 60.

Trump Account: tax-deferred, not tax-free

A Trump Account works like a traditional IRA. Contributions from parents, relatives, and friends aren’t deductible, but because that money was already taxed, it comes back out tax-free later. Everything else is taxed as ordinary income when it’s withdrawn: the growth, the $1,000 federal deposit, and any employer contributions, which went in tax-free, according to Fidelity. Withdrawals before 59½ can also owe a 10% penalty unless an exception applies. There’s a wrinkle, too: withdrawals count as unearned income, so part of a withdrawal by a young adult who is still a dependent student can be taxed at the parents’ rate under the kiddie tax, Fidelity notes. Even so, the seed money is hard to beat. At a hypothetical 7% average annual return, the $1,000 federal deposit alone could grow to about $3,380 by age 18.

In short, the 529 plan and the Roth IRA offer tax-free growth, the Trump Account defers tax until the money comes out, and a custodial account offers only a small break on its first dollars of income each year.

Spending flexibility compared

Tax breaks come with strings. As a rule, the more a tax break is worth, the more rules there are about how the money can be spent.

Custodial account: anything that benefits your child

While your child is a minor, a UTMA or UGMA account is the most flexible of the four. The custodian can spend it on anything “for the use and benefit of the minor,” though custodians shouldn’t use it for everyday living expenses, according to Schwab MoneyWise. The catch comes after the handoff: once the custodianship ends, your child can spend the money on anything at all.

529 plan: education, broadly defined

A 529 plan pays for education, and the definition keeps widening. Tax-free withdrawals can cover college tuition, fees, and books; room and board for students enrolled at least half-time; up to $20,000 a year of K-12 expenses; registered apprenticeships and professional credentials; and up to $10,000 of student loan payments over a lifetime, according to Saving for College. Since July 4, 2025, K-12 expenses have included more than tuition, such as books, tutoring, and standardized test fees. The earnings on money spent for anything else are taxed, plus a 10% penalty, and some states don’t follow every federal rule.

If plans change, a 529 has more escape hatches than it used to. You can switch the beneficiary to another member of your child’s family, according to Saving for College’s guide to 529 ownership. And once an account has been open 15 years, up to $35,000 over a lifetime can move into the beneficiary’s own Roth IRA, within the yearly Roth limit and only if the beneficiary has earned income, as Saving for College’s rollover guide explains. The SECURE 2.0 Act: Rolling 529 Funds into a Roth IRA walks through the rules.

Custodial Roth IRA: reachable, but best left alone

Because contributions can be withdrawn at any time, a Roth is more flexible than it looks. Earnings are another matter: taking them out early generally means income tax plus a 10% penalty, though the IRS waives the penalty for certain uses, including qualified higher education expenses and up to $10,000 toward a first home. The real value of a child’s Roth is decades of untaxed growth, so most families treat it as off-limits.

Trump Account: locked until 18, then IRA rules

While your child is young, a Trump Account is the least flexible of the four. Money generally can’t be withdrawn before January 1 of the year your child turns 18, according to IR-2025-117. After that, the account is generally treated like a traditional IRA: your child can withdraw for any reason, but withdrawals before 59½ face a 10% penalty unless an exception applies, such as certain education expenses, a first-home purchase (up to $10,000), or birth or adoption costs (up to $5,000), Fidelity explains. Income tax is due on the taxable part either way.

If flexibility is your priority, a custodial account wins while your child is young and loses once they come of age. A 529 now covers far more than college, and the Roth and the Trump Account are built for the long haul.

Contribution limits for 2026

Here’s how much can go into each account this year, and from whom.

• 529 plan. There’s no federal annual limit, though each state caps the total you can contribute per child, at amounts ranging from about $269,000 to more than $600,000, according to Saving for College’s 2026 limits guide. What matters most years is the gift tax: in 2026, each person can give a child up to $19,000 without filing a gift tax return, and a 529 plan uniquely lets one giver contribute up to $95,000 at once, or $190,000 for a married couple, by electing to spread it over five years.
• Custodial account. No limit, but the same $19,000 gift tax exclusion applies to each giver.
• Custodial Roth IRA. In 2026, up to $7,500 or your child’s taxable compensation for the year, whichever is less, according to the IRS. The money doesn’t have to come from your child’s paycheck: a parent or grandparent can fund the contribution, as long as the total doesn’t exceed what your child earned, Bankrate notes. What Qualifies as “Earned Income” for a Minor’s Roth IRA? explains which jobs count.
• Trump Account. Family, friends, and employers together can contribute up to $5,000 a year, and an employer can put in up to $2,500 of that per employee without it counting as the employee’s taxable income, according to IR-2025-117. Both limits rise with inflation after 2027. The $1,000 federal deposit and contributions from governments and charities don’t count toward the cap, according to Fidelity.

Employer contributions are just getting started. The IRS proposed rules for employer Trump Account programs in August 2026, in news release IR-2026-90, and some employers may also let parents send part of their own pay into a child’s account before income tax, Fidelity explains. An employer’s $2,500 is per employee, not per child, so a parent with two children may see it divided between them. Navigating 530A Employer Contributions covers how these programs work.

Gifts to different accounts can also interact. Under a safe harbor announced in IRS news release IR-2026-80, many relatives who give to a Trump Account won’t need to file a gift tax return for it. But the safe harbor applies only if the giver’s gifts to the child stay within $19,000 for the year and the giver doesn’t file a gift tax return that year for another reason, such as superfunding a 529 plan, according to accounting firm Yeo & Yeo. The Impact of the 2026 Gift Tax Exclusion explains the rules for larger gifts.

Age of transfer: when your child takes control

This is the difference parents most often overlook, and it’s the hardest one to undo. It answers a simple question: at what point is the money legally your child’s to spend?

• You or another adult
• Handoff age, set by state law
• Your child

Custodial account ages are each state’s UTMA default: 21 in 41 states, 18 in eight states and the District of Columbia, and 22 in Louisiana. About 10 states let the person opening the account choose a later age, typically up to 25, and Wyoming allows up to 30. A custodial Roth IRA transfers at the state’s age of majority.

529 plan: you stay in control

A 529 plan never transfers to your child automatically. As the account owner, you decide how it’s invested and when money comes out, and you can change the beneficiary, according to Saving for College’s guide to 529 ownership. That’s why it’s worth naming a successor owner to take over if something happens to you, as Naming Successor Custodians explains. The exception is a custodial 529 funded with UTMA or UGMA money. There, your child is the owner and takes control at the age of majority, which is 18, 19, or 21 depending on the state.

Custodial account: an age set by state law

A UTMA or UGMA account belongs to your child from day one, and the custodianship ends at an age set by your state. For a UTMA account, that age is 21 in 41 states and 18 in a handful, and several states let the person opening the account choose a later age, typically up to 25, according to FinAid. Wyoming allows as late as 30. If your state offers a later age, choose it when you open the account, since you can’t change it afterward, Schwab MoneyWise notes. At the handoff, your child gets complete control and can sell the investments or close the account. What Happens at the Age of Majority? covers what to expect.

Custodial Roth IRA: the age of majority

The custodian manages a custodial Roth IRA until your child reaches the age of majority, between 18 and 21 depending on the state, when your child can transfer it into an account in their own name, according to Vanguard. From then on it’s an ordinary Roth IRA, and the tax rules, rather than you, are what encourage your child to leave it alone.

Trump Account: 18

A parent or guardian acts for your child until 18, and after that the account is your child’s to manage under traditional IRA rules, according to Fidelity. Fidelity adds that converting it to a Roth IRA may become an option for your child, though the IRS hasn’t spelled out the details. The Hand-Off: Safely Withdrawing and Transitioning Wealth and The “Wealth Transfer” Conversation cover how to prepare a teen for the day the money becomes theirs.

How each account affects financial aid

If your child might qualify for need-based aid, ownership matters. On the FAFSA, a dependent student’s assets are assessed at up to 20%, compared with up to 5.64% for parents’ assets, and a 529 plan a parent sets up for the student counts as a parent asset, according to CollegeData. In practice, $10,000 in a custodial account could reduce aid eligibility by up to $2,000 in each year it’s reported, compared with up to $564 for the same money in a parent-owned 529.

Retirement accounts, including Roth IRAs, aren’t reported as assets on the FAFSA, though withdrawals from them count as income on later applications, CollegeData notes. The FAFSA also leaves out 529 plans owned by grandparents, and families with a combined income of $60,000 or less don’t have their assets counted at all.

Trump Accounts are the open question. As of July 2026, the Education Department hadn’t said how to report them, and experts disagreed: Mark Kantrowitz expects them to count as student assets, while Kalman Chany notes that IRAs generally aren’t reportable assets and that the accounts could be treated more like retirement accounts once a child turns 18, Benzinga reported. By September, The College Investor reported that college planners generally assume the accounts will be assessed as student assets, at up to 20%, so that’s the safer way to plan until official guidance arrives. Chany still recommends claiming the $1,000 deposit, reasoning that in the worst case a family wouldn’t lose more aid than the seed-funded account is worth. How 529s and UTMAs Impact the FAFSA goes deeper.

Which account fits which goal

You don’t need to master every rule to choose well. Start with what the money is for.

Many families use more than one account for the same child. Federal rules for 2026.

If you’re not sure how to divide savings between school and everything else, Setting Realistic Goals: Balancing College vs. General Wealth walks through it.

Using more than one account

These accounts aren’t rivals, and nothing stops you from using several for the same child. Fidelity describes Trump Accounts as a possible complement to 529 plans, Roth IRAs, and custodial accounts rather than a replacement for them. A layered plan for a young child might look like this:

1. Claim the free money first. If your child is eligible, elect the $1,000 federal deposit on IRS Form 4547, which you can complete through your IRS Individual Online Account, according to IR-2026-96. Ask whether your employer contributes, too. How to Claim the Federal Seed Money Pilot has the steps.
2. Make a 529 plan the core of education savings. It has the best tax treatment for school costs, keeps you in control, and counts lightly for financial aid.
3. Add flexible money if you want it. A custodial account suits gifts meant for your child to use someday on anything. If you’d rather keep control, an account in your own name can do a similar job; Custodial Brokerage Accounts vs. Parent-Owned Taxable Accounts compares the two, and Understanding Trust Funds for the Middle Class covers larger sums.
4. Open a Roth when the first paycheck arrives. A teen job unlocks the most tax-efficient account on this list. Teen Brokerage Accounts vs. Custodial Accounts covers accounts that let teens place their own trades.

One rule comes before all of these: make sure your own retirement savings are on track, as The “Oxygen Mask” Rule of Parental Finance explains. And when the money is finally needed, Liquidating Safely covers how to draw it down in the right order.

Where family gifts fit in

Every account on this list can take money from grandparents, aunts, uncles, and friends, which turns birthdays and holidays into a real source of savings. GoodNest helps with that part: loved ones can give toward your child’s future from your child’s GoodNest page, often alongside a small keepsake like a book. GoodNest doesn’t hold or invest the money. Family send gifts straight to you by Zelle, Venmo, or PayPal, and you move them into whichever account fits. Set that account on the page, and it tells givers where their gift is going.

A few account rules are worth keeping in mind as gifts arrive:

• Trump Account. The $5,000 yearly cap covers everyone combined, employers included, so keep a running total if several people give.
• Custodial Roth IRA. Gifts can fund it only up to what your teen earned that year.
• Custodial account. Every dollar becomes your child’s at the handoff age, so it suits gifts meant for your child’s future, not money you might need back.
• 529 plan. The natural home for gifts meant for school, and the one you keep control of.

The bottom line

There’s no single best investment account for kids, only the best account for a particular goal. A 529 plan is the strongest tool for education and keeps you in charge. A custodial account is the most flexible, at the cost of handing your child the money at an age your state sets. A custodial Roth IRA is the best deal of all once your teen has a paycheck. And if your child qualifies for the $1,000 deposit, a Trump Account is worth opening for the free money alone, even if most of your savings go elsewhere. Choose by purpose, use more than one account if it helps, and send family gifts wherever they’ll do the most good.

Frequently asked questions

What is the best investment account for a child?

It depends on the goal. For education, a 529 plan usually comes out ahead: growth is tax-free when it’s spent on qualified costs, you keep control, and a parent-owned 529 counts lightly for financial aid. For money your child can use on anything, a UTMA or UGMA custodial account is the most flexible, though it becomes your child’s at an age set by state law. If your child has a job, a custodial Roth IRA offers decades of tax-free growth. And if your child is a U.S. citizen born from 2025 through 2028, a Trump Account lets you claim a $1,000 federal deposit.

Is a Trump Account better than a 529 plan?

They do different jobs. A 529 plan offers tax-free withdrawals for qualified education expenses, stays under your control, and counts as a parent asset for financial aid. A Trump Account needs no earned income and may come with a $1,000 federal deposit, but money generally can’t come out before the year your child turns 18, everything beyond the family’s after-tax contributions is taxed as ordinary income when withdrawn, and its financial aid treatment isn’t settled. Many families claim the Trump Account seed money and keep college savings in a 529.

At what age does my child get control of the account?

It depends on the account. A 529 plan never transfers automatically; the owner keeps control. A UTMA custodial account transfers at an age set by state law, which is 21 in most states and 18 in some, with several states allowing later ages such as 25. A custodial Roth IRA transfers at the age of majority, between 18 and 21 depending on the state. A Trump Account is managed by a parent or guardian until your child turns 18.

Which account is best for financial aid?

A parent-owned 529 plan. On the FAFSA it counts as a parent asset, assessed at up to 5.64%, while a custodial account counts as the student’s asset, assessed at up to 20%. Roth IRAs aren’t reported as assets, though withdrawals count as income, and 529 plans owned by grandparents aren’t reported at all. The Education Department hadn’t issued guidance on Trump Accounts as of mid-2026, and many planners assume they’ll count as student assets.

How much can I put into each account in 2026?

A 529 plan has no federal annual limit, though a giver who puts in more than $19,000 for one child generally has to file a gift tax return, and each state caps the total per child. A custodial account has no limit, subject to the same gift tax rules. A custodial Roth IRA can take up to $7,500 or your child’s earnings for the year, whichever is less. A Trump Account can take up to $5,000 a year from family, friends, and employers combined, plus the $1,000 federal deposit and any government or charity contributions, which don’t count toward the cap.
