What Is the Kiddie Tax?
The "kiddie tax" is a provision in the U.S. Internal Revenue Code designed to prevent parents from avoiding taxes by shifting investment income to their children, who typically face lower marginal tax rates. Under the kiddie tax rules, a child's unearned income above a specified threshold — for 2024, $2,500, with the first $1,250 being tax-free and the next $1,250 taxed at the child's rate — is taxed at the parents' marginal tax rate rather than the child's typically lower rate. The tax applies to children under age 18, full-time students under age 24 whose earned income does not exceed half of their support, and, in certain cases, children whose parents have elected specific filing options. The kiddie tax is a classic example of a tax anti-abuse rule: closing a loophole that would otherwise allow high-income families to significantly reduce their overall tax burden through income splitting with minor children.
How the Kiddie Tax Works
The mechanics are straightforward but require careful calculation. First, determine the child's gross unearned income — this includes interest, dividends, capital gains, rental income, royalties, and certain trust distributions. Earned income from wages or self-employment is not subject to the kiddie tax. Second, subtract the standard allowance. For 2024, the first $1,250 of unearned income is exempt from all tax (the standard deduction equivalent), and the next $1,250 is taxed at the child's own rate. Any unearned income exceeding $2,500 is taxed at the parents' top marginal rate. The tax is reported on Form 8615, attached to the child's tax return, or parents can elect to report the child's income on their own return using Form 8814 if certain conditions are met. Notably, changes introduced by the Tax Cuts and Jobs Act of 2017 briefly altered the kiddie tax to use trust and estate tax rates rather than the parents' rate — a change that inadvertently increased taxes for some families, including Gold Star families receiving military survivor benefits. Congress subsequently restored the parents' rate calculation in the SECURE Act of 2019, making the restoration retroactive and addressing the unintended hardship.
Strategies to Minimize Kiddie Tax Impact
While the kiddie tax limits straightforward income shifting, legitimate planning strategies remain. First, invest children's assets in growth-oriented investments that produce minimal current taxable income — such as growth stocks with low or no dividends, Series EE or I savings bonds whose interest can be deferred until redemption, or tax-managed mutual funds — rather than high-dividend stocks or taxable bonds. Second, utilize tax-advantaged accounts: 529 college savings plans grow tax-free when used for qualified education expenses, and Coverdell Education Savings Accounts offer similar benefits. Third, for teenagers with earned income, funding a Roth IRA — which grows tax-free — with their earnings provides long-term tax benefits without kiddie tax implications. Fourth, consider making gifts of appreciated assets to children after they reach the age where kiddie tax no longer applies — age 18 for non-students, or 24+ for full-time students — allowing them to realize capital gains at their own lower rate. Fifth, for larger family wealth transfers, explore trusts designed to accumulate income while the child is subject to the kiddie tax and distribute it later. Each strategy involves trade-offs between tax efficiency, control, and the child's access to funds.
Common Misconceptions
Many families mistakenly believe the kiddie tax applies to all children's income. In reality, earned income — wages from a part-time or summer job — is taxed entirely at the child's rate, not the parents' rate. A teenager earning $5,000 from a summer job pays tax on that $5,000 at their own marginal rate, typically 10-12%, regardless of their parents' tax bracket. Another misconception is that all unearned income above the threshold is taxed at the parents' rate. The tax applies at the margin, not retroactively to the first dollar of unearned income. The first $1,250 remains tax-free, the next $1,250 is at the child's rate, and only amounts above $2,500 are at the parent's rate. Also, the kiddie tax does not apply to children who are married and filing jointly, nor to children who provide more than half of their own support from earned income.
Why the Kiddie Tax Matters for Family Financial Planning
The kiddie tax fundamentally affects how families should structure their children's investment accounts and intergenerational wealth transfers. For grandparents or parents planning to gift appreciated stock to a child, the tax consequences depend heavily on the child's age: before the kiddie tax expires, selling the stock may trigger tax at the parents' rate, negating some of the benefit of the gift. For families with significant UGMA/UTMA custodial accounts established for children, managing those accounts to minimize current taxable income while the child is subject to the kiddie tax can materially improve after-tax returns over time. For tax professionals, the kiddie tax's legislative history — the 2017-2019 changes and retroactive fix — serves as a reminder that even seemingly settled tax rules can change with significant consequences, and that ongoing monitoring of tax law developments is essential.
FAQ
Does the kiddie tax apply to scholarship income?
Generally, no. Qualified scholarships used for tuition and required fees are tax-free and not considered unearned income subject to the kiddie tax. However, scholarship amounts used for room and board or other non-qualified expenses may be taxable and could potentially be classified as unearned income if they represent payment for services or if specific conditions apply. The rules are nuanced, and professional tax advice is recommended.
Can parents avoid the kiddie tax by not filing a return for the child?
No. The child has an independent filing obligation if their income exceeds the filing threshold. Failing to file does not avoid the tax — it creates a compliance problem that can result in penalties and interest. If the child owes kiddie tax, Form 8615 must be filed. Parents who elect to report the child's income on their own return using Form 8814 must meet all eligibility conditions.

Kiddie tax is a word used to refer to a tax provision that affects children with investment income in the United States. A child's investment income that exceeds a specific threshold is subject to the kiddie tax rule, which taxes it at the parent's higher rate rather than the child's lower rate.
The kiddie tax was enacted as a component of the Tax Reform Act of 1986 to stop wealthy families from moving money to their kids who were exempt from paying as much in taxes. Children under the age of 18, kids beyond the age of 18 whose earnings do not exceed half of their support, and full-time students between the ages of 19 and 23 whose earnings do not exceed half of their support, are all subject to the kiddie tax.
Every year, the child tax threshold is raised to account for inflation. The threshold is $2,400 in unearned income for the 2022 tax year. Earned income, such as salary from part-time employment, is exempt from the kiddie tax.
The kiddie tax rule has a few exceptions, including when a child gets married and files a joint tax return or when the child's investment income comes from a qualified disability trust. By making investments on behalf of their children in tax-exempt or tax-deferred accounts, parents may also be able to avoid the kiddie tax.
