If your child earns investment income from savings accounts, stocks, mutual funds, or other investments, understanding the 2026 kiddie tax is an important part of family tax planning. Many parents assume that all of a child’s investment income is taxed at the child’s lower tax rate. But federal tax rules may require a portion of that income to be taxed at the parent’s higher marginal tax rate.

Whether you’re investing for your child’s future or helping them build wealth early in life, knowing how the kiddie tax works can help you avoid unexpected unexpected consequences.

What Is the 2026 Kiddie Tax?

The 2026 kiddie tax is a federal tax rule designed to prevent families from shifting investment income to children solely to reduce taxes. When a qualifying child has enough unearned income, the IRS taxes part of that income using the parent’s tax rate instead of the child’s lower rate.

Unearned income usually includes

• Taxable scholarships in some situations
• Certain trust distributions
• Capital gain distributions from mutual funds
• Dividend income
• Capital gains
• Interest income

The kiddie tax does not apply to earned income such as wages from a job.

2026 Kiddie Tax Thresholds

For the 2026 tax year:

• The first $1,350 of unearned income is generally tax-free, but the next $1,350 is generally taxed at the child’s tax rate.
• Unearned income over $2,700 is usually taxed at the parent’s marginal tax rate.

Although these thresholds remain unchanged from the prior tax year, families should review them annually because IRS inflation adjustments can affect other tax provisions.

Who Does the Kiddie Tax Apply To?

The kiddie tax generally applies if the child:

• Is under age 18 at the end of the tax year.
• Has more than $2,700 of unearned income.
• Is age 18 and does not provide more than half of their own support through earned income.
• Has at least one living parent and does not file a joint return.
• Is a full-time student between ages 19 and 23 and does not provide more than half of their own support through earned income.
• Files a federal income tax return.

Examples of Income Subject to the Kiddie Tax

Parents are often surprised by what qualifies as unearned income. Common examples include:

• Investment earnings in custodial accounts
• Capital gains from selling investments
• Mutual fund distributions
• Stock dividends
• Savings account interest

Income from self-employment, working a summer job, or part-time employment is generally not subject to the kiddie tax.

Planning Opportunities for Parents

The kiddie tax can increase your family’s overall tax bill when a child earns investment income. If this applies to your situation, it may be worthwhile to review the investments held in your child’s custodial account and carefully plan when investment gains are realized.

For example, investments focused on long-term growth rather than current income may help minimize exposure to the kiddie tax while your child is still subject to these rules. Once the kiddie tax no longer applies, selling appreciated investments may allow any taxable gains to be taxed at your child’s own rate. Oftentimes, this rate is lower than the parents’ rate.
