Investment Accounts for Kids: How to Save for Their Future

Being a parent hands you endless opportunities to teach your kids something valuable, even when they don't seem to be listening. Investing is one of the best gifts you can give them, and it starts long before they're old enough to understand what a stock is.

There's no magic number you need to start with. What matters is starting, because the earlier money goes to work for your child, the more time compound growth has to do the heavy lifting. A modest amount invested consistently over 15 or 18 years can grow into something genuinely meaningful, and along the way, you have a built-in opportunity to teach your kids how money actually works.

The tricky part is that there isn't one single “kids investment account.” There are several, each designed for a different purpose, with different rules, tax treatment, and levels of control. Here's how to think through the options.

Types of Investment Accounts for Kids

529 Plans

If your primary goal is funding future education costs, a 529 plan is usually the first place to look. These accounts are specifically built for education savings, and they come with a few clear advantages.

• High contribution limits. Most state plans allow substantial lifetime contributions, and anyone, grandparents included, can contribute to a child's 529.

• Tax advantages. Contributions aren't deductible on your federal return, but the money grows tax-free, and withdrawals are tax-free when used for qualified education expenses. Contributions made as a gift are also removed from the contributor's estate for tax purposes.

• Flexibility. If one child doesn't use all the funds, the balance can be redirected to a sibling, another relative, or even yourself. Under current law, unused 529 funds can also be rolled into a Roth IRA for the beneficiary after the account has been open 15 years, subject to annual and lifetime limits, which gives what used to be a rigid account a genuine escape hatch.

Custodial Roth IRA

If your child has earned income, whether from a part-time job, babysitting, dog-walking, or helping out with your business, they may qualify for a custodial Roth IRA. You open and manage the account until your child reaches the age of majority in your state, typically 18 or 21.

Contribution limits are tied to earned income: your child can contribute up to the lesser of the annual IRA limit or what they actually earned that year. What makes this account special is the combination of decades of potential tax-free growth with real flexibility:

• Contributions (though not earnings) can be withdrawn tax-free at any time for any purpose, including a car or a home down payment.

• Earnings can be withdrawn tax-free and penalty-free when used for qualified education expenses.

• After the account has been open five years, your child can withdraw up to $10,000 in earnings toward a first home purchase, tax-free and penalty-free.

If your child can leave the money alone through their childhood and into their working years, the combination of an early start and decades of compounding can turn even modest contributions into a genuinely significant nest egg by the time they reach retirement age themselves.

Coverdell Education Savings Accounts

A Coverdell account functions similarly to a 529: contributions grow tax-free, and withdrawals are tax-free when used for qualifying education expenses, including K-12 costs in some cases, which 529 plans didn't always cover as flexibly.

The trade-off is that Coverdell accounts come with a much lower annual contribution cap, currently $2,000 per year per beneficiary, and the ability to contribute phases out at higher household incomes. For most families saving significant amounts for college, a 529 plan will do more of the work.

UGMA/UTMA Custodial Accounts

Accounts under the Uniform Gift to Minors Act or Uniform Transfer to Minors Act are custodial accounts that hold assets on a child's behalf, with a parent or other relative acting as custodian until the child reaches the age of majority in their state, which can range from 18 to 25 depending on where you live.

The custodian can invest contributions into stocks, bonds, or mutual funds, and other family members can contribute as well. The key difference from a 529 or Coverdell is flexibility of use: withdrawals from a UGMA/UTMA can go toward anything that benefits the child, not just education. The trade-off is fewer tax advantages, and once your child reaches the age of majority, the account and everything in it becomes fully theirs to use as they choose, whether or not that aligns with what you had in mind.

Brokerage Accounts for Teens

Several major brokers now offer accounts designed specifically for teenagers, allowing them to buy stocks, ETFs, and mutual funds directly. Unlike custodial accounts, some of these give ownership to the child from the start rather than requiring a custodian, though parental oversight is still worth maintaining.

These accounts can be a genuinely fun way to get kids interested in investing early, letting them pick a company or two they recognize and watch it move over time. The investment amounts don't need to be large to make the lesson land.

530(A) Trump Accounts: a Brand New Option

Trump Accounts are new tax-deferred investment accounts designed to give children an early start on retirement savings. Parents, grandparents, employers, and others can generally contribute up to a combined $5,000 per year. Eligible children born from 2025 through 2028 may also receive a one-time $1,000 federal contribution. During childhood, the money must be invested in qualifying low-cost U.S. stock index funds and generally can't be withdrawn.

These accounts may appeal to families who want to take advantage of the federal or an employer contribution and give the money decades to grow. However, they are less flexible than 529 plans or custodial brokerage accounts because the account becomes a traditional IRA under the child’s control at age 18. Early withdrawals may be subject to taxes and a penalty. For that reason, a Trump Account is best considered alongside other ways to save for a child rather than as an automatic first choice.

At What Age Should You Start?

There's no universal right answer here, and it depends on your child's attention span as much as anything else. Some experts suggest starting conversations about investing as early as age eight, but the honest answer is that it's rarely too early or too late to begin. What matters more than the exact starting age is making it engaging: picking a stock together, checking in on it periodically, and letting your child see the connection between patience and growth.

Competing with video games and social media for a teenager's attention around money is a real challenge, but framing investing as something you're building together, rather than a lecture, tends to land better than any spreadsheet.

What You're Probably Wondering

Which account should I open first: a 529 or a custodial account?

If your primary goal is covering future education costs, start with a 529 for its tax advantages and high contribution limits. If your child has earned income and you want to introduce them to long-term, tax-free investing beyond just education, a custodial Roth IRA is worth adding alongside it. Many families end up using both.

What happens to a UGMA/UTMA account if my child doesn't use it for college?

Nothing forces them to. Unlike a 529, funds in a UGMA/UTMA can be used for anything that benefits the child. The account simply transfers fully to your child's control once they reach the age of majority in your state, and from that point forward, the decision about how to use it is theirs.

Can grandparents or other relatives contribute to these accounts?

Yes, in most cases. 529 plans in particular are designed to accept contributions from anyone, which makes them a popular choice for birthday and holiday gifts. UGMA/UTMA accounts can also accept contributions from other family members, though the custodian remains the one managing the assets.

Does my child need earned income to have any investment account at all?

No. Earned income is only required for a custodial Roth IRA, since IRA contributions are tied to income by law. 529 plans, Coverdell accounts, UGMA/UTMA accounts, and teen brokerage accounts don't require your child to have a job.

How much should I start with?

Whatever you can contribute consistently matters more than the size of any single contribution. A modest, regular amount invested over 10 to 18 years benefits enormously from compound growth. Starting small and staying consistent will usually outperform waiting until you can contribute a larger amount all at once.

The Bottom Line

Investment accounts for kids do double duty: they build real, tax-advantaged wealth over time, and they give you a natural, ongoing way to teach your children how money grows. You don't need to get every detail perfect on the first try. Pick the account that fits your immediate goal, whether that's education, a broader head start, or simply sparking curiosity, and let time do a lot of the rest.

At Life Story Financial, I help families think through which combination of accounts fits their goals, their budget, and their timeline, whether that's a 529 for college, a custodial Roth IRA to jump-start retirement savings decades early, or both. If you'd like help building that plan for your family, I'd be glad to talk it through with you.
