How to Avoid the "Kiddie Tax" on Your Child’s Investment Income

This means if your child's brokerage account generates $5,000 in dividends, the excess $2,300 could cost you thousands extra at your rate—far more than if it stayed in your portfolio.

Who Does the Kiddie Tax Apply To in 2026?

Not every kid with a savings account triggers it. The kiddie tax hits:

• Children under 18 at year-end.
• 18-year-olds who didn't provide more than half their own support.
• Full-time students ages 19-23 who also didn't cover over half their support.

Your child must file a return (if unearned income tops $1,350), not file jointly, and at least one parent must be alive. Use IRS Form 8615 to calculate it on their return—or in some cases, report it on yours via Form 8814.

Why the Kiddie Tax Matters for American Families

With rising college costs and the push for early financial education, many parents open UGMA/UTMA custodial accounts or brokerage accounts for kids. But if those investments spit out more than $2,700 in unearned income, you're hit with your 32%, 35%, or even 37% bracket on the excess.

Take this example: Your 16-year-old has $4,000 in dividends. The first $2,700 is lightly taxed, but the remaining $1,300? If you're in the 24% bracket, that's $312 extra—multiplied across years, it adds up fast. Plus, high earners might owe the 3.8% Net Investment Income Tax (NIIT) on top via Form 8960.

How to Avoid the Kiddie Tax: Proven Strategies

The good news? You can structure investments to stay under thresholds or use tax-advantaged vehicles. Here's actionable advice tailored for U.S. families.

1. Keep Unearned Income Under $2,700

Simple math: Limit investments generating interest, dividends, or gains.

• Opt for low-yield savings or growth stocks with minimal distributions.
• Time sales to realize gains under the limit—e.g., hold long-term for lower 0-15% capital gains rates at the child's level.
• Shift to tax-efficient ETFs or index funds that rarely distribute taxable gains.

Pro tip: A $20,000 portfolio in high-dividend funds could easily exceed limits; aim for total return via appreciation instead.

2. Use 529 Plans—They're Kiddie Tax-Free

College savers rejoice: Earnings in 529 plans grow tax-deferred and are tax-free for qualified education expenses, dodging the kiddie tax entirely—even in custodial accounts. Contribute after-tax dollars, and Uncle Sam rewards qualified withdrawals (tuition, books, even some K-12 up to $10,000/year).

In 2026, no income phaseouts apply, and you can front-load up to $18,000 per parent ($36,000 couple) gift-tax-free, or superfund $90,000 over five years. Bonus: Rollovers to Roth IRAs are now allowed tax-free after 15 years.

3. Leverage Roth IRAs for Kids with Earned Income

If your teen has a job (W-2 wages count as earned income), open a Roth IRA. Contribute up to $7,000 (2026 limit, or their earned income, whichever is less). All growth is tax-free on qualified withdrawals after age 59½—and it sidesteps kiddie tax since it's not current unearned income.

Assets in Roths also get favorable treatment in FAFSA financial aid formulas. Example: Babysitting earnings fund a Roth invested in stocks; dividends compound tax-free.

4. Employ Parent Election with Form 8814

For modest income ($12,000 or less total, under $2,700 unearned), elect to report it on your return via Form 8814. No separate child filing needed, but special rates apply—handy if your bracket isn't much higher.

5. Shift to Earned Income or Trusts

Encourage jobs: Wages up to the standard deduction ($15,000 max for dependents) are taxed lightly at kid rates. For larger portfolios, consider trusts where income stays with parents or qualifies for exceptions.

Long-term capital gains under kiddie rules often blend child/parent rates, so hold investments over a year.

Common Mistakes to Avoid

• Forgetting NIIT: Kids with net investment income over thresholds owe 3.8% if MAGI exceeds limits.
• Ignoring state taxes: Some states mirror federal kiddie rules—check your state's revenue department.
• Over-gifting without planning: UGMA/UTMA assets become child's at majority (18-21), but tax hits earlier.
