The Uniform Transfers to Minors Act is a state law that lets an adult give money or property to a child through a custodial account, with an adult custodian managing the assets until the child reaches the age set by state law. At that point, the entire balance passes to the child outright, with no conditions on how it’s spent. The gift is irrevocable the moment it funds the account: the donor cannot pull it back, change the beneficiary, or dictate how the money is eventually used.
Every state except South Carolina has adopted UTMA. It replaced and expanded an older law, the Uniform Gifts to Minors Act, and the two still coexist in practice.
UTMA Compared to UGMA
UGMA came first and limits custodial property to financial assets: cash, stocks, bonds, and mutual funds. UTMA covers nearly any kind of property, including real estate, life insurance policies, royalties, patents, and fine art. South Carolina still operates under UGMA rules, so transfers there are limited to traditional financial instruments. In UTMA states, UGMA accounts are still available and commonly used for straightforward gifts of cash and securities.
Opening and Titling a Custodial Account
You open a custodial account through a bank, brokerage, or similar institution. You provide identifying information for the donor, the custodian, and the child, and then fund the account. The donor picks the initial custodian, who can be the donor personally, though doing so creates an estate-tax issue discussed below.
The title has to reflect the custodial relationship, usually something like “[Custodian’s Name], as Custodian for [Minor’s Name] under the [State Name] Uniform Transfers to Minors Act.” That wording legally separates the custodial property from the custodian’s own assets. For deposit insurance, the FDIC treats a properly titled UTMA or UGMA account as the minor’s account, not the custodian’s.1Federal Deposit Insurance Corporation.

The child’s Social Security number goes on the account because the child is the legal owner. All tax reporting runs through the child’s SSN. Once the transfer is complete, the gift is done.
What the Custodian Can and Cannot Do
A custodian holds the property in a fiduciary capacity, meaning the law requires managing it solely for the child’s benefit. The governing standard is the “prudent person” rule: handle the child’s assets with the same care and judgment a reasonable person would use when managing someone else’s property. In practice, that favors diversified, age-appropriate investments and rules out speculative bets. Loading a ten-year-old’s account with leveraged options is almost certainly a violation.
Custodians have to keep custodial property completely separate from their own finances and maintain clear transaction records, which also feed the child’s annual tax return. The money can be spent on things that benefit the child, such as education, extracurricular activities, or medical care. It generally should not be used for basic necessities like food and shelter that a parent is already legally obligated to provide. If custodial money is used for those expenses, the Social Security Administration may treat the spending as in-kind support income to the child, which can affect benefit eligibility.2Social Security Administration.

A custodian who mismanages the account, makes unsuitable investments, or dips into the funds personally can be sued by the beneficiary for breach of fiduciary duty. A court can order the custodian to repay losses, step down, and cover the beneficiary’s legal fees. Borrowing from the account with plans to repay it later counts as a violation.
When the Child Takes Control
The custodianship ends automatically when the child reaches the termination age set by state law. That age varies. Most states set it at 21, some use 18, and a number of states let the donor pick an age as late as 25. At termination, the custodian has to transfer full title and control of every remaining asset to the now-adult beneficiary.
The transfer is unconditional. The former minor can spend the money on tuition, a car, a trip, or nothing productive at all. The donor has no legal mechanism to prevent this, which is why people transferring large sums often prefer formal trusts that allow spending restrictions. Financial institutions typically flag the account as the beneficiary approaches the specified age and may restrict the custodian’s access until the handover is completed.
One detail donors often miss: the termination age cannot be extended after the account is created. It has to be chosen at the time of the initial transfer, within whatever range state law allows. If you set it at 18 and later wish you had chosen 21, the only option is to move the assets into a formal trust before termination, and that raises its own legal complications because the property already belongs to the child.
Taxes on a UTMA Account
Gift Tax
Contributions count against the federal gift tax annual exclusion. For 2026, you can give up to $19,000 per recipient without filing a gift tax return or using any lifetime exemption.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Married couples can combine their exclusions for up to $38,000 per child per year. Gifts above the limit require filing Form 709, though no actual tax is owed until the lifetime exemption is used up, which stands above $13 million for 2026.4Internal Revenue Service.

Kiddie Tax
Interest, dividends, and capital gains inside the account are taxed under the child’s SSN, and the “kiddie tax” rules apply. For 2026, the first $1,350 of a child’s unearned income is tax-free. The next $1,350 is taxed at the child’s own rate, usually low. Anything above $2,700 is taxed at the parent’s marginal rate, which erases most of the benefit of shifting income to a lower bracket.5Internal Revenue Service. Instructions for Form 8615
The Donor-as-Custodian Estate Trap
If you fund a custodial account and name yourself as custodian, the IRS can pull those assets back into your taxable estate if you die before the custodianship ends. The theory is that, as custodian, you kept the power to decide how and when the property is distributed, which the tax code treats as a power to alter or terminate the transfer.6Office of the Law Revision Counsel. 26 USC 2038 – Revocable Transfers For most families, this won’t actually trigger estate tax because the federal exemption is so high. For high-net-worth donors, the safer approach is to name someone else as custodian.
Effect on College Financial Aid and Benefits
Because UTMA and UGMA assets belong to the child, the FAFSA counts them as student assets, which are assessed at 20% when calculating the Student Aid Index. Parent-held assets like a 529 plan are assessed at a much lower rate, capped around 5.64%. Withdrawals from a custodial account can also count as student income on the following year’s FAFSA, further reducing need-based aid, while qualified 529 withdrawals do not. If the goal is specifically education savings, a 529 is usually the better choice. Custodial accounts fit better when you want to give a child flexible assets that aren’t restricted to education expenses.
Means-tested government benefits are another concern. Because the assets belong to the child, they count toward eligibility limits for programs like Supplemental Security Income. A child with a sizable custodial balance can lose benefits they would otherwise qualify for.
If the Custodian Dies or Cannot Serve
A custodian can name a successor at any time with a written designation, and many states allow this to be done by will. The designation does not take effect while the current custodian is alive and able to serve. It kicks in only on death, incapacity, resignation, or removal. If you’re the custodian and haven’t named a successor, it’s simple paperwork that heads off a court proceeding later.
When a custodian dies or becomes incapacitated without naming a successor, most state statutes provide a fallback sequence. In many states, a minor who has reached age 14 can designate a successor from among adult family members, a guardian, or a trust company. If the child is younger than 14 or doesn’t act within a set time frame (often 60 days), the child’s legal guardian becomes successor custodian. If there is no guardian or the guardian declines, an interested party can petition a court to appoint one. The assets remain protected throughout, since they belong to the minor regardless of who manages them.
Before You Open One
The limitation most donors underestimate is irrevocability combined with unconditional termination. Once the money is in the account, it belongs to the child, and at the termination age it is theirs to spend however they want. You cannot attach conditions, delay the payout, or redirect the funds to a sibling. If you want the money tied to a specific purpose or released on your terms, a 529 plan or a formal trust gives you far more control than UTMA does.
