A UTMA or UGMA account is a custodial account that holds property legally owned by a minor and managed by an adult custodian until the child reaches the age set by state law. UGMA stands for the Uniform Gifts to Minors Act. UTMA stands for the Uniform Transfers to Minors Act. Both are model laws that states adopt, and both let an adult give assets to a child without creating a formal trust or going through a court-appointed guardianship. The practical difference is the range of property each allows: UGMA accounts hold cash and securities, while UTMA accounts can also hold real estate, patents, royalties, fine art and other property.

How a UTMA or UGMA Account Works

A custodial account has three roles. The donor gives the property. The custodian controls the account, makes investment decisions and can spend money for the child’s benefit. The minor, sometimes called the beneficiary, is the legal owner. The donor can serve as custodian or name someone else, such as a parent, grandparent or other trusted adult.

Banks and brokerages typically open these accounts in the form “Custodian name, as custodian for Child name, under the [State] Uniform Transfers to Minors Act.” A state code is sometimes added to the acronym (for example, CUTMA for California), and “FBO” means “for the benefit of,” marking the minor as the owner.

Several rules follow from the minor’s ownership:

• The gift is irrevocable. Once property goes into the account, the donor cannot reclaim it, and the custodian cannot redirect it to another child.
• One owner per account. A custodial account has a single minor beneficiary. Siblings each need their own account.
• Spending must benefit the child. The custodian can withdraw money for expenses that serve the minor, such as education, camps or a computer. Using custodial funds to cover a parent’s basic support obligations, or for the custodian’s own purposes, breaches the fiduciary duty.
• Contributions are made with after-tax money. The donor gets no income tax deduction for putting money in.

Anyone can contribute once the account exists, and the money can be invested in the same assets as a regular brokerage account, so long-term growth through compound interest and reinvested returns accrues to the child.

UTMA vs. UGMA: What’s the Difference?

The UGMA came first. The National Conference of Commissioners on Uniform State Laws developed it in 1956 and revised it in 1966. It was limited to transfers of cash and securities. The UTMA, finalized in 1986, builds on the UGMA’s language and extends the definition of property a minor can receive. A UTMA account can hold:

• Cash
• Stocks and bonds
• Mutual funds and other investments
• Real estate
• Patents and other intellectual property
• Royalties
• Fine art

Most states have adopted the UTMA, and in those states it generally replaced the older UGMA statute. South Carolina has not adopted the UTMA. Because both are uniform laws rather than federal statutes, every state can modify its version, so the rules for an account depend on the state under whose law it was created.

The two acts also differ in timing. UGMA custodianship commonly ends at the age of majority, often 18, while UTMA statutes more often extend control to 21, which can give assets such as bonds more time to mature.

Taxes on UTMA and UGMA Accounts

Two separate tax regimes apply: gift tax on money going in, and income tax on what the account earns.

Gift tax

A contribution is a completed gift to the minor. For 2026, the IRS annual gift tax exclusion is $19,000 per recipient, unchanged from the previous year. A donor can give up to that amount to a child in a year without filing a gift tax return. A married couple can each give $19,000 to the same child, for $38,000 combined. Gifts above the exclusion do not automatically trigger tax due; they require a gift tax return and reduce the donor’s lifetime exemption. There is no separate contribution cap for custodial accounts.

Income tax and the kiddie tax

Interest, dividends and capital gains earned in the account are the child’s unearned income and are reported under the child’s Social Security number. To keep families from shifting large investment portfolios into a child’s lower bracket, the kiddie tax applies. The 2026 thresholds are:

1. The first $1,350 of the child’s unearned income is tax-free.
2. The next $1,350 is taxed at the child’s rate.
3. Unearned income above $2,700 is taxed at the parent’s marginal rate.

The kiddie tax generally applies to children under 19, and to full-time students under 24, subject to IRS conditions on earned income and support. Once the child ages out of those rules, account income is taxed entirely at the child’s own rates.

Worked example (hypothetical)

Assume a 12-year-old has no earned income and a UTMA account that generates $3,500 of dividends and interest in 2026. Under the thresholds above:

Only the last $800 is taxed at the parent’s rate. If the same $3,500 had been earned in the parent’s own taxable account, all of it would have been taxed at the parent’s rates. The saving shrinks as account income grows, because more of it falls into the parent-rate slice.

Selling appreciated assets inside the account creates capital gains for the child, and those gains count toward the same thresholds. Withdrawals by the custodian for the child’s benefit are not themselves taxable events; only the income and gains the investments produce are.

When the Child Takes Control

Custodianship ends when the minor reaches the termination age in the governing state statute, and the custodian must then transfer the assets to the young adult. The age is typically 18 or 21. Some states allow the donor to choose a later age when making the gift: Florida, for example, passed a statute in 2015 that allows UTMA property to remain with the custodian until the beneficiary turns 25 if the transfer specifies it. In some jurisdictions, the account can be released at 18 with the custodian’s agreement and transfers automatically at 21.

The account does not move by itself. The custodian, or the new adult owner, usually completes a transfer request with the bank or brokerage holding it, and the assets are moved into an account in the young adult’s own name. After that, the former minor can spend the money on anything. Neither the donor nor the custodian can impose conditions, such as requiring the money go to tuition, unless the assets were placed in a trust instead.

Estate Considerations

Although the property belongs to the minor, it can still affect the donor’s estate. If the donor names themself as custodian and dies before the custodianship ends, the value of the account is included in the donor’s taxable estate. Naming a different adult as custodian avoids that result.

If a custodian dies or can no longer serve, the account is not frozen indefinitely. State UTMA statutes provide for a successor custodian, who may be named in advance by the custodian, designated by the minor once they reach a certain age (often 14), or appointed by a court.

Limitations of a UTMA or UGMA Account

• Loss of control at the termination age. The biggest drawback for many families. A substantial balance becomes the young adult’s outright property, whatever their maturity or plans.
• Financial aid impact. On federal aid formulas, assets owned by the student are assessed at a higher rate than assets owned by parents. Because a custodial account belongs to the child, it can reduce eligibility for need-based aid and some scholarships.
• Limited tax benefit. Earnings are taxed every year, and the kiddie tax caps the advantage of the child’s lower rate.
• State variation. Termination ages, permitted property and successor rules differ, which matters when a family moves or a donor lives in a different state from the child.

UTMA/UGMA vs. 529 Plan vs. Trust

Families often weigh a custodial account against two alternatives.

A 529 plan is designed for education. Earnings grow tax-deferred and qualified education withdrawals are federally tax-free. The account owner, usually a parent, keeps control and can change the beneficiary to another family member. A parent-owned 529 is treated as a parent asset for federal aid, which is generally more favorable than a student-owned custodial account. For a child headed to college, a 529 is often the better fit. A custodial account is more flexible in what the money can be spent on, which suits goals beyond education.

A trust costs more to set up and administer, but it lets the grantor set conditions: distribution ages, permitted uses and what happens if the beneficiary dies. A trust fund is the usual choice when the amount is large or the donor wants control past age 21. A custodial account offers the simplicity of a standard brokerage or bank account in exchange for giving up that control.

It is also possible to move custodial assets into a 529 plan, but because the money already belongs to the child, it goes into a custodial 529 account that keeps the child as owner, and investments usually must be sold first, which can realize capital gains.

The Bottom Line

Custodial accounts suit parents and grandparents who want a simple way to give a child assets that can be spent on many goals, not just school. The tradeoff is that the young adult gets full control at the state's termination age, usually 18 or 21. Families focused on college often get better tax and aid treatment from a 529 plan, and donors who want lasting conditions generally need a trust.
