Investment Accounts for Kids: A Parent's Complete Guide (2026)

Starting an investment account for your child early may allow compound growth to work over a longer time horizon. Compound growth means earnings on an investment may themselves generate additional earnings over time. The SEC notes that even small, consistent contributions can grow meaningfully over decades when left invested. Investing always carries risk, including the possible loss of principal — past performance does not guarantee future results. See also: how many bank accounts you should have.

A custodial account is opened by an adult — typically a parent or guardian — on behalf of a minor under the Uniform Gifts to Minors Act (UGMA) or the Uniform Transfers to Minors Act (UTMA). The adult manages the account until the child reaches the age of majority, which is typically 18 or 21 depending on the state. At that point, the assets transfer fully to the child with no restrictions on how they are used. Custodial accounts can hold stocks, bonds, mutual funds, and ETFs, but contributions are irrevocable gifts — the money legally belongs to the child.

Custodial account earnings may be subject to the "kiddie tax," under which a portion of a child's unearned income above a threshold may be taxed at the parent's rate. The IRS publishes the kiddie tax thresholds annually, so confirm current figures at IRS.gov. Because ownership transfers at majority, custodial assets may reduce the child's eligibility for need-based college financial aid more than parent-owned assets would.

A 529 plan is a tax-advantaged savings account designed primarily for education expenses. Contributions to a 529 plan grow tax-deferred, and qualified withdrawals — used for tuition, fees, books, and certain room and board costs — are generally tax-free at the federal level. Many states also offer a state income tax deduction or credit for contributions to their own plan. The account owner (typically a parent) retains control of the funds and can change the beneficiary to another family member if needed.

As of 2026, federal law also allows up to $35,000 of unused 529 funds to be rolled into a Roth IRA for the beneficiary, subject to annual Roth IRA contribution limits and a 15-year account ownership requirement. Non-qualified withdrawals are subject to income tax and a 10% federal penalty on earnings. Investment options within 529 plans vary by state and typically include age-based portfolios and index funds. See also: how early saving impacts compound interest.

A teen who has earned income — from a part-time job, self-employment, or similar work — may be eligible to contribute to a Roth IRA. As of 2026, the annual Roth IRA contribution limit is the lesser of the individual's earned income or $7,000 (confirm the current-year limit at IRS.gov). A custodial Roth IRA is typically opened and managed by a parent until the child reaches the age of majority. Roth IRA contributions are made with after-tax dollars, meaning qualified withdrawals in retirement may be tax-free.

Because teens are typically in a low or zero tax bracket, contributing to a Roth IRA when young may offer long-term tax advantages. However, contributions must not exceed the teen's actual earned income for the year. The IRS defines earned income as wages, salaries, tips, and net self-employment income — investment income does not count. A teen with $3,000 in summer job earnings could contribute up to $3,000 to a Roth IRA for that tax year. See also: investing in the S&P 500.

Custodial brokerage accounts (UGMA/UTMA) offer the most flexibility — funds can be used for any purpose at any time, not just college or retirement. However, they lack the tax advantages of 529 plans or Roth IRAs. Retirement accounts like Roth IRAs have contribution limits and require earned income, but offer significant long-term tax benefits. The right choice depends on your family's goals, the child's situation, and your tax picture — a fiduciary financial advisor can help you compare options for your specific circumstances.

All investment accounts carry market risk — the value of investments can decline, and you may lose money. SIPC-member brokerages protect accounts up to $500,000 (including $250,000 in cash) against broker failure, but SIPC does not protect against investment losses. Custodial accounts are irrevocable, meaning you cannot reclaim assets transferred to the child's account. Tax rules around the kiddie tax, 529 withdrawals, and Roth IRA eligibility change periodically — always verify current rules at IRS.gov before acting.
