Setting your child up for financial success starts with a combination of smart account choices, early investing, and age-appropriate money lessons that build real habits over time. The earlier you begin, the more powerful compound growth becomes. A parent who invests $100 a month starting at their child’s birth, earning a 7% average annual return, would have roughly $48,000 by the time that child turns 18. The same investment started at age 10 yields less than half that amount. But money in accounts is only part of the equation. Teaching your child how to think about money matters just as much as the dollars you set aside.
Choose the Right Accounts
Three account types dominate when it comes to investing for a child: 529 education savings plans, UTMA/UGMA custodial accounts, and custodial Roth IRAs. Each has different tax treatment, flexibility, and implications for college financial aid, so the right choice depends on what you want the money to eventually do.
529 Plans
A 529 plan is the most tax-efficient way to save for education. Contributions grow tax-free at the federal level, and withdrawals are also tax-free as long as you use them for qualified education expenses like tuition, room and board, books, and required supplies. Many states offer a state income tax deduction or credit for contributions, which adds another layer of savings. The trade-off is that money withdrawn for non-education purposes gets hit with income taxes on the earnings plus a 10% penalty.
That restriction loosened significantly with the SECURE 2.0 Act. If your child doesn’t use all the 529 funds for school, you can now roll over up to $35,000 from the 529 into a Roth IRA in the child’s name over their lifetime. The 529 account must have been open for at least 15 years, the transferred amount must come from contributions made at least five years before the rollover, and each year’s rollover can’t exceed the annual Roth IRA contribution limit. This makes 529 plans far less risky than they used to be, since leftover funds no longer have to sit trapped or get penalized.
For financial aid purposes, a 529 plan owned by a parent (or a custodial 529 in the child’s name) is treated as a parental asset, which has a much smaller impact on aid eligibility than money held directly in a child’s name.
UTMA/UGMA Custodial Accounts
A custodial account under the Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA) lets you invest in stocks, bonds, mutual funds, or other assets on behalf of your child. The money can be used for any purpose that benefits the child, not just education, which makes these accounts more flexible than a 529. The child gains full control of the account when they reach the age of majority (18 or 21, depending on your state).
The downside is tax treatment. Your child owes income tax on any appreciation or earnings in the account. And in financial aid calculations, custodial accounts count as the child’s asset, which reduces aid eligibility more than a parent-owned 529. These accounts work best when you want to give your child a general-purpose financial head start and aren’t worried about the financial aid impact.
Custodial Roth IRA
If your child has earned income from a job, babysitting, lawn mowing, or any legitimate work, you can open a custodial Roth IRA in their name. Contributions are made with after-tax dollars, and then the money grows tax-free for decades. A teenager who puts even a few thousand dollars into a Roth IRA has an enormous runway for compound growth before retirement.
The key requirement is that your child must have actual earned income, and their contribution can’t exceed what they earned that year. You can fund the contribution yourself (it’s your money going in), as long as it doesn’t exceed the child’s earnings. This is one of the most powerful long-term wealth-building tools available because of how many decades that money has to compound.
Start Investing Early and Consistently
The specific investments you choose matter less than the habit of starting early and staying consistent. For long time horizons of 15 to 18 years or more, a diversified, low-cost index fund is hard to beat. Many 529 plans offer age-based portfolios that automatically shift from stocks toward bonds as your child approaches college age, which simplifies the decision.
For custodial accounts and custodial Roth IRAs, a total stock market index fund or a target-date fund provides broad diversification without requiring active management. The power of compounding over a child’s lifetime is staggering. Even modest, regular contributions of $50 or $100 a month can grow into significant sums over 18 years because the returns themselves generate returns year after year.
One practical approach: set up automatic monthly contributions so the investing happens without you having to remember. Treat it like any other recurring bill. If grandparents or other family members want to contribute to birthday or holiday gifts, direct them toward one of these accounts instead of toys or gift cards.
Use Gift Tax Rules to Your Advantage
The IRS allows you to give up to $19,000 per recipient per year (for both 2025 and 2026) without triggering any gift tax or needing to file a gift tax return. For a married couple, that’s $38,000 per child per year. This means both parents can fund a child’s 529, custodial account, or Roth IRA generously without any tax complications.
529 plans also offer a special provision called superfunding, which lets you front-load up to five years’ worth of the annual gift exclusion in a single year. For one parent, that’s up to $95,000 at once. This gets more money working in the market sooner, which amplifies the compounding effect. You simply elect to spread the gift over five years on your tax return, and you can’t make additional gifts to that beneficiary during that period.
Build Their Credit Before They Need It
Adding your child as an authorized user on one of your credit cards can give them a credit history before they ever apply for their own card. Once they’re added (or once they turn 18, depending on the card issuer’s reporting policy), the account’s entire payment history gets added to their credit reports. If you’ve maintained that card with on-time payments and low balances, your child could start adulthood with an established credit profile instead of a blank one.
Some issuers allow authorized users as young as 13 or 15, though policies vary. Before adding your child, contact the issuer to confirm they’ll report the authorized user status to the credit bureaus while the child is still a minor. Some issuers won’t report until the user turns 18, which reduces the head start. And be careful: if you carry a high balance or miss a payment on that account, it could hurt your child’s credit rather than help it. Only use this strategy with a card you manage responsibly.
You don’t need to give your child the physical card. The credit-building benefit comes from being listed on the account, not from making purchases.
Teach Money Skills by Age
Accounts and investments build wealth, but financial literacy builds the judgment your child needs to manage that wealth. The Consumer Financial Protection Bureau identifies core money skills that develop in stages during childhood, starting with patience, persistence, and the ability to recognize trade-offs. These are the building blocks of every financial decision an adult makes.
For young children (ages 3 to 6), focus on the basics: counting coins, understanding that things cost money, and practicing patience when they want something. A clear jar where they can see savings grow is more effective than an abstract piggy bank. Let them make small choices, like picking between two treats at the store, so they start experiencing trade-offs firsthand.
For elementary-age kids (7 to 12), introduce an allowance tied to saving, spending, and giving categories. This is the age when children can grasp that money is finite and that spending it on one thing means not having it for something else. Open a savings account in their name and let them see the balance grow. Talk about prices when you shop together. Let them make mistakes with small amounts now so the lessons are cheap.
For teenagers (13 to 18), shift toward real-world financial skills. Help them open a checking account and debit card. Walk them through how a paycheck works if they get a part-time job, including the surprise of seeing taxes withheld for the first time. Introduce the concept of investing by showing them a real brokerage or Roth IRA account and explaining what the numbers mean. Talk about how credit cards work, what interest costs in real dollars, and what a credit score is before they leave for college and start getting card offers in the mail.
Match Their Earnings to Supercharge Saving
Once your teenager starts earning money, consider matching their savings dollar for dollar, the same way an employer match works in a 401(k). If they earn $3,000 from a summer job and save $1,500, you contribute another $1,500 to their Roth IRA or savings account. This teaches them that saving has immediate rewards, and it accelerates the growth of their accounts during the years when compound interest has the longest runway.
The matching approach also gives your child skin in the game. Research consistently shows that people value money more and spend it more carefully when they earned or contributed to it themselves. A teenager who watches their own earnings grow in an investment account develops a relationship with saving that lasts well beyond childhood.
Protect What You’ve Built
Setting your child up financially also means making sure your own financial foundation is secure. If something happened to you, would your child still have access to the resources you’ve been building? Life insurance, particularly a term policy during your child’s growing-up years, ensures that your family’s financial plan survives even a worst-case scenario. Name a guardian in your will who shares your values around money, and make sure that person knows about the accounts you’ve set up.
For custodial accounts and 529 plans, designate a successor custodian or account owner so the assets transfer smoothly. These are small administrative steps that take minutes to set up but prevent months of legal complications if they’re ever needed.
