Can High-Income U.S. Parents Avoid Higher Taxes by Investing Through Their Children's Accounts?

Many high-income U.S. taxpayers wonder whether they can reduce their overall tax burden by transferring investment assets to their children. For example, if stocks are held in a child's account instead of a parent's, can the dividend income be taxed at the child's lower tax rate rather than the parent's higher rate?

The answer is: not necessarily.

To prevent this type of income-shifting strategy, the Internal Revenue Service (IRS) has established the Kiddie Tax rules. Contrary to what the name suggests, Kiddie Tax is not a special tax imposed on children. Instead, its primary purpose is to prevent high-income families from reducing their overall tax liability by transferring investment assets to children who are subject to lower income tax rates.

The Tax Logic Behind Kiddie Tax

The United States uses a progressive income tax system, meaning that higher levels of taxable income are generally subject to higher marginal tax rates, with the highest federal rate currently reaching 37%. By contrast, children often fall into much lower tax brackets because they have little or no earned income.

Consider the following example. Suppose a parent is in the 37% federal income tax bracket and transfers a portfolio of dividend-paying stocks to a minor child. Without the Kiddie Tax rules, future dividend income could potentially be taxed at the child's much lower tax rate instead of the parent's. Although the family's total wealth has not changed, the family would have significantly reduced its overall federal income tax liability simply by shifting the ownership of the investment.

To address this loophole, Congress enacted the Kiddie Tax provisions. The underlying principle is straightforward: parents are free to make legitimate gifts of investment assets to their children, but transferring ownership alone should not automatically allow investment income that would otherwise be taxed at the parents' higher tax rate to qualify for the child's lower tax rate.

What Types of Income Trigger Kiddie Tax?

Whether Kiddie Tax applies does not depend on whether a child has income. Instead, it depends on the type of income the child receives.

Generally, earned income, such as wages from part-time jobs, internships, or campus employment, is not subject to Kiddie Tax because it is compensation earned through the child's own labor.

By contrast, unearned income may be subject to Kiddie Tax. This includes interest earned on bank accounts, dividends, mutual fund distributions, ETF distributions, capital gains, and other investment income. When a child's net unearned income exceeds the annual IRS threshold, the excess amount may be taxed under the Kiddie Tax rules.

Are All of the Child's Income Taxed at the Parents' Tax Rate?

No. One of the most common misconceptions about Kiddie Tax is that once it applies, all of the child's income becomes taxable at the parents' tax rate. That is not how the law works.

Kiddie Tax affects only the portion of the child's net unearned income that exceeds the applicable statutory threshold. The child's earned income, such as wages from a summer job or part-time employment, continues to be taxed under the child's own tax rules and tax rates. Therefore, triggering Kiddie Tax does not cause all of the child's income to be taxed at the parents' higher marginal rate.

Can Parents Still Claim the Child as a Dependent?

Yes. Whether a child is subject to Kiddie Tax and whether the parents may claim the child as a dependent are two separate tax concepts.

As long as the child continues to satisfy the IRS requirements for a Qualifying Child, including the applicable age, relationship, residency, and support tests, the parents may still claim the child as a dependent even if the child is subject to Kiddie Tax.

Can the Child Still File an Independent Tax Return?

Yes. If the child is otherwise required to file an individual income tax return, the application of Kiddie Tax does not change that filing obligation.

The child remains a separate taxpayer and generally files his or her own Form 1040. If the Kiddie Tax rules apply, the child simply includes Form 8615 (Tax for Certain Children Who Have Unearned Income) with the tax return to calculate the tax on the applicable portion of the investment income.

In other words, Kiddie Tax changes how part of the child's investment income is taxed, not the child's status as an independent taxpayer.

Helping Your Children Invest Early While Staying Tax Compliant

Many families begin investing for their children's future at an early age by opening custodial accounts or purchasing ETFs, mutual funds, or individual stocks as part of long-term education or wealth-building plans. These strategies are entirely legitimate, and owning investment assets in a child's name does not, by itself, violate any IRS rules. However, as investment income grows, parents should monitor whether the child has become subject to the Kiddie Tax rules and whether Form 8615 is required.

Families with international investments should exercise additional caution. If a child owns foreign mutual funds or other non-U.S. investment products, additional U.S. international reporting requirements may apply, including the Passive Foreign Investment Company (PFIC) rules (Form 8621), FBAR (FinCEN Form 114) for foreign financial accounts, and Form 8938 (Statement of Specified Foreign Financial Assets).

Proper planning can help families build wealth for the next generation while remaining fully compliant with U.S. tax law. Understanding the Kiddie Tax rules is an important part of that planning, particularly for families with significant investment portfolios or cross-border assets.
