Parents who want to give a teenager exposure to investing have more options than ever, but the labels on those options can mislead.

For example, Fidelity Youth Account and a Fidelity Custodial Account both hold a minor's investments, both can buy stocks and ETFs, and both market themselves to families. Yet they answer two different questions: who owns the money, and who controls it.

With Acorns Early, Greenlight Invest+, Schwab, E*TRADE, and a growing set of teen banking apps now offering some flavor of investment account, the labels have only grown more confusing.

Here's what to know about the difference between teen investing accounts and UGMA/UTMA accounts.

Teen Brokerages: The Minor Owns and Trades

A teen brokerage account, sometimes called a youth account, is opened in the minor's name with a parent's consent. The defining feature is operational control. The teen places trades, transfers money, and manages the account directly.

Fidelity launched the most prominent example, the Fidelity Youth Account, for teens ages 13 to 17. It carries no account fees, no minimums, and includes a debit card. A parent must hold a Fidelity account to open one, and parents receive monthly activity statements and can monitor trades, but they do not approve them. When the teen turns 18, the account converts automatically into a standard Fidelity brokerage account in the teen's name.

Step, an app aimed at teens, offers a similar structure with stock and crypto investing tied to a teen-owned banking account. These products are designed to teach money management through experience.

The trade-off is that the money in the account is the teen's money. Once a parent or grandparent contributes funds, they cannot reverse the transfer. The teen can spend it, invest it aggressively, or withdraw it at 18 without parental approval.

UGMA/UTMA: The Minor Owns but the Custodian Controls

Custodial accounts created under the Uniform Gifts to Minors Act or the Uniform Transfers to Minors Act work differently. The minor is still the legal owner, but a custodian (usually a parent or grandparent) controls every transaction until the child reaches the state's age of majority. That age is 18 in most states, 21 in others, and as high as 25 in a handful of states under specific UTMA provisions.

Acorns Early is a UGMA/UTMA wrapped in an automated investing app. Charles Schwab, E*TRADE, Vanguard, and Fidelity all offer traditional UGMA/UTMA custodial brokerage accounts. Greenlight Invest+ uses a parent-controlled structure where the parent approves every teen-initiated trade, functionally similar to a custodial setup even when not formally branded UGMA/UTMA.

Contributions to a UGMA or UTMA are irrevocable gifts. Once money goes in, it belongs to the child. The custodian must use the assets for the child's benefit and hand over full control on the day the child reaches the age of majority.

How Taxes Work

Both account types trigger the federal kiddie tax, which was designed to stop families from shifting investment income to a child's lower bracket. The 2026 thresholds, which adjust annually for inflation, work in three tiers for unearned income such as dividends and capital gains:

• The first $1,350 is offset by the child's standard deduction and is effectively tax-free.
• The next $1,350 is taxed at the child's rate.
• Anything above $2,700 is taxed at the parent's marginal rate.

Tax outcomes are similar across both account types because the IRS taxes the owner of the assets, and in both cases that owner is the child.

How These Accounts Impact FAFSA Reporting

Financial aid is where many families learn the hard way that "the kid's account" really means the kid's account. Under the FAFSA's Student Aid Index methodology, student-owned assets count toward expected family contribution at 20%. Parent-owned assets count at a maximum of 5.64%.

A $20,000 Fidelity Youth Account or a $20,000 UTMA brokerage can shrink a financial aid package by up to $4,000 a year. The same $20,000 sitting in a parent-owned 529 plan would reduce aid by no more than $1,128. For families relying on need-based aid, that gap compounds over four years.

What This Means For Families

A teen brokerage account is best understood as a teaching tool. The teen funds it, often from a part-time job or birthday gifts, and learns to invest with money they control. Parents who want their child to learn about markets without handing over a large gift may find a Fidelity Youth Account or Step account a better fit than a custodial structure.

A UGMA/UTMA is better understood as a transfer of wealth. It works for grandparents who want to lock in a gift, take advantage of the kiddie tax brackets at smaller balances, and pass control of the money on a fixed timeline. It is a poor fit for families who later wish they could redirect the money toward a sibling, repurpose it for a different goal, or shield it from financial aid formulas.

Neither product is interchangeable with a 529 plan, a Roth IRA for kids with earned income, or a parent-owned taxable brokerage. Each structure has different ownership, control, tax, and aid consequences.
