Setting aside money for your child’s future is one of the most responsible things a parent can do—but it’s not always as simple as opening a savings account and letting it grow. Believe it or not, child savings can be hit with unexpected taxes that reduce the very funds you’ve worked hard to build. From interest income to gift limits and even scholarship-related tax rules, there are hidden costs parents don’t always see coming. Without a little planning and awareness, the IRS could end up claiming a bigger chunk of your child’s nest egg than you ever intended. Here are 11 tax surprises that can quietly erode child savings—and what you can do to protect them.
1. The Kiddie Tax Rule
One of the most well-known threats to child savings is the Kiddie Tax. This rule taxes a child’s unearned income—like interest, dividends, or capital gains—at the parent’s tax rate once it exceeds a certain threshold. For 2024, the first \$1,250 is tax-free, the next \$1,250 is taxed at the child’s rate, and anything above that is taxed at the parent’s rate. That can come as a big shock when your child’s savings begin to grow. It’s a clear reminder that even a kid’s investment income isn’t off-limits to the IRS.
2. Interest on Savings Accounts
That simple high-yield savings account might be quietly creating taxable income each year. Any interest your child earns—even just a few dollars—needs to be reported to the IRS. If the account is in the child’s name, the income is theirs, but it may still trigger the Kiddie Tax depending on the amount. These taxes can creep in and chip away at the total balance over time. Always review annual statements to know what’s being earned and reported.
3. UTMA/UGMA Account Taxation
Uniform Transfers to Minors Act (UTMA) and Uniform Gifts to Minors Act (UGMA) accounts are popular tools for child savings, but they’re not tax-free. While the first portions of unearned income are taxed at favorable rates, larger amounts can quickly get hit by the Kiddie Tax. Plus, once the child turns 18 or 21 (depending on the state), they gain full control of the account—including the tax responsibilities. These accounts are useful, but they come with strings attached.
4. Taxable Scholarships
Not all scholarship money is tax-free. If your child receives scholarship funds that go toward room, board, or travel expenses—not tuition or required fees—they may owe taxes on that portion. Many families assume scholarships are completely tax-exempt and don’t prepare for this twist. If those funds are deposited into savings or investment accounts, they may further complicate your child’s tax filing. It’s important to understand what scholarship dollars cover and how they’re reported.
5. Tax on Capital Gains
If your child’s savings include investments like stocks, ETFs, or mutual funds, selling those assets for a profit can trigger capital gains taxes. While long-term gains often benefit from lower rates, short-term gains are taxed as ordinary income. That means if you sell to rebalance or cash out part of the account, there could be a surprise tax bill. Teaching kids about investing is great—but managing taxes on those investments is part of the lesson.
6. 529 Plan Withdrawal Mistakes
529 plans offer tax-free growth if the funds are used for qualified education expenses. But if you withdraw more than needed or use the money for non-qualified expenses, the earnings portion becomes taxable and may also face a 10% penalty. Timing withdrawals and matching them to tuition or fees is key to avoiding this issue. A simple planning error can reduce the power of these popular child savings vehicles.
7. Gift Tax Reporting
If grandparents or relatives contribute more than the annual exclusion amount—\$18,000 per donor, per child in 2024—it may trigger a gift tax filing requirement. The giver, not the child, is responsible, but the IRS still takes note. While most won’t owe taxes thanks to the lifetime exemption, paperwork still needs to be filed. These gifts can still affect how much money your child has access to and how it’s taxed down the road.
8. Income from Freelance or Gig Work
As your child gets older, they may earn money through side gigs like tutoring, selling crafts online, or babysitting. Even small amounts can be subject to self-employment tax if they earn more than \$400 from a business-like activity. Many families overlook this when adding earnings to child savings accounts. If your child is working independently, a separate savings strategy with tax planning may be needed.
9. Inherited Accounts
If a child inherits a retirement account or brokerage fund, required minimum distributions (RMDs) and taxes can quickly complicate things. Inherited IRAs, in particular, have strict distribution rules and tax implications. These inherited funds may seem like a windfall but can easily shrink if not handled correctly. Always speak to a financial advisor when a child receives an inheritance involving investments.
10. Dividends from Stocks or Mutual Funds
Even if no money is withdrawn, mutual funds and some stocks pay dividends that are taxable each year. These are considered unearned income and can trigger Kiddie Tax thresholds or increase the child’s overall taxable income. If those dividends are automatically reinvested, you might miss the tax impact until it’s time to file. It’s a sneaky way child savings can lose value through taxation.
11. State-Level Taxes and Penalties
Federal taxes get most of the attention, but don’t forget about state-level rules. Some states tax 529 plan withdrawals, investment earnings, or savings interest differently than federal guidelines. Even if you follow all federal tax rules, your child’s account could be taxed locally. Checking both federal and state tax rules is a smart move for long-term savings protection.
Planning Now Prevents Panic Later
It’s easy to assume that child savings accounts are too small or innocent to face serious tax issues—but the truth is, even modest growth can trigger unexpected obligations. By staying informed about how these accounts are taxed, you can shield your child’s money from avoidable losses. Whether you’re using a traditional savings account, a 529 plan, or a UTMA, regular review and smart planning go a long way. Don’t let the IRS take a bite out of your child’s future without you realizing it.
