A UGMA account is a custodial account under the Uniform Gifts to Minors Act that lets an adult gift cash and securities to a child without setting up a trust. An adult custodian manages the money as a fiduciary until the child reaches the age of majority set by state law, at which point the child gets full, unrestricted control. The gift is irrevocable from the moment it hits the account, investment income is taxed to the child under Kiddie Tax rules, and the balance counts as the student’s asset on the FAFSA. Those four points drive almost every rule that follows.
What a UGMA Account Can Hold
UGMA accounts are limited to financial assets: cash, stocks, bonds, and mutual funds. They cannot hold real estate, art, patents, royalties, or other tangible or intangible property.1Social Security Administration. POMS SI 01120.205 – Uniform Transfers to Minors Act
Most states have replaced the UGMA framework with the broader Uniform Transfers to Minors Act, which accepts virtually any kind of property. A handful of states still operate under the older UGMA rules. Which statute governs an account depends on the state law designated in the transfer, generally the state where the donor, custodian, minor, or property resides. If your state has moved to UTMA, that is what you will actually open at a brokerage; the tax and control rules discussed below apply to both.
Setting Up the Account
Two people define the account. The donor makes the gift. The custodian manages the account until the child comes of age. They can be the same person, but making them the same person creates an estate tax problem covered further down.
Each account has exactly one minor beneficiary. You cannot set up a single custodial account for multiple children, and you cannot change the beneficiary later.2HelpWithMyBank.gov. What Is a UGMA or UTMA Account Three grandchildren means three accounts.
The account is opened at a brokerage or bank using the minor’s Social Security number and the custodian’s identifying information, and titled in a form like “Jane Doe, as Custodian for John Doe under the [State] Uniform Gifts to Minors Act.” Once assets are transferred in, the gift is legally irrevocable. The donor cannot take the money back, redirect it to someone else, or attach conditions after the fact.2HelpWithMyBank.gov. What Is a UGMA or UTMA Account
How the Custodian Must Manage the Money
The custodian is a fiduciary. Every decision has to be made in the child’s interest, not the custodian’s, and state law generally imposes a prudent-person standard: manage the money the way a reasonable person would manage their own. Speculative trades that might be fine in a personal account are not appropriate here. The custodian also cannot commingle custodial assets with personal funds or use the account for personal benefit under any circumstances.
Spending is where families get into trouble. The custodian can spend the money on anything that benefits the child, but a tax trap sits inside that flexibility. Under most state statutes, custodial funds can be spent without regard to whether a parent could also afford to pay. If custodial income is actually used to cover something a parent is legally obligated to provide, such as basic food, shelter, or clothing, the IRS can treat that income as taxable to the parent rather than the child.
The safer path is to use custodial funds for expenses clearly beyond basic support: private school tuition, enrichment programs, a laptop for school, travel for academic competitions, or college application fees. Where “support” ends and “beyond support” begins varies by state, so records matter. The custodian should document every deposit, withdrawal, and investment decision. When the child reaches majority, they have the legal right to demand a full accounting, and a custodian who cannot produce satisfactory records can be held personally liable.
How Custodial Income Is Taxed
Interest, dividends, and capital gains earned in the account are taxed to the child, not the donor or custodian. The child reports the unearned income on their own return. The IRS limits the benefit of shifting that income to a child’s low bracket through what is commonly called the Kiddie Tax.
The Kiddie Tax applies to children under 18, to 18-year-olds who do not earn more than half their own support, and to full-time students between 19 and 23 who do not earn more than half their own support.3Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax) For 2026, the thresholds work like this:
- The first $1,350 of unearned income is covered by the child’s standard deduction and is tax-free.
- The next $1,350 is taxed at the child’s own marginal rate, which is usually low.
- Anything above $2,700 is taxed at the parent’s marginal rate, wiping out most of the tax advantage.4Internal Revenue Service. Instructions for Form 8615
The child calculates this on Form 8615, attached to their own return. Capital gains follow the same tiers. Short-term gains on assets held a year or less are taxed as ordinary income.5Internal Revenue Service. Topic No. 409, Capital Gains and Losses Long-term gains get preferential rates, but the portion above $2,700 is taxed at the parent’s long-term capital gains rate rather than the child’s.
The Form 8814 Election
If the child’s only income is interest, dividends, and capital gain distributions totaling less than $13,500, parents can elect to report it on their own return using Form 8814 instead of filing a separate return for the child.3Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax) The election simplifies paperwork but raises the parents’ adjusted gross income, which can reduce eligibility for income-based credits and deductions. The convenience is not always worth the trade-off.
Gift Tax Rules for Contributors
Every contribution to a custodial account is a completed gift for federal tax purposes. For 2026, an individual can give up to $19,000 per recipient per year without any gift tax reporting.6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A married couple can combine exclusions to give up to $38,000 per child per year through gift splitting.
Contributions above $19,000 to a single child in one year have to be reported on Form 709. That does not necessarily mean tax is owed. It reduces the donor’s lifetime gift and estate tax exemption, which for 2026 is $15,000,000.7Internal Revenue Service. What’s New – Estate and Gift Tax Very few families ever owe federal gift tax, but the reporting requirement still applies.
When the Child Takes Control
The custodial relationship ends by law when the child reaches the age of majority set by the governing state statute. The default termination age is 18 in some states and 21 in others. Several states allow the donor to specify a later termination age at the time of the original transfer, commonly up to 25.2HelpWithMyBank.gov. What Is a UGMA or UTMA Account
Whether or not the custodian believes the young adult is financially mature, the transfer has to happen. The custodian has no legal authority to withhold the assets, convert them into a trust, or impose conditions. The custodian instructs the financial institution to re-register the account in the beneficiary’s name alone, and from that point the young adult can spend the money on anything.
If a beneficiary reaches the termination age and the custodian refuses to hand over the assets, the beneficiary can petition the court to compel the transfer, remove the custodian, and demand a formal accounting.
If the minor dies before reaching the age of majority, the custodial property transfers to the minor’s estate. It does not revert to the donor.
The Financial Aid Cost
UGMA balances are reported as the student’s assets on the FAFSA, not the parent’s.8Federal Student Aid. Net Worth of Your Investments The federal aid formula assesses student assets at 20%, meaning one-fifth of the balance is expected to go toward college costs each year. Parent-owned assets like a regular brokerage account are assessed at no more than 5.64%. A $50,000 custodial account reduces aid eligibility by roughly $10,000 per year; $50,000 in a parent’s name reduces it by about $2,820. Schools that use the CSS Profile for institutional aid go further, assessing student assets at 25%.
For a family that expects to qualify for need-based aid, the aid hit can easily exceed the lifetime tax savings the account produced. That is worth running the numbers on before making a large contribution.
The Estate Tax Trap for Donor-Custodians
If the person who makes the gift also serves as custodian and dies before the child reaches the termination age, the full value of the custodial account is pulled into the donor’s taxable estate.9Office of the Law Revision Counsel. 26 US Code 2038 – Revocable Transfers The IRS treats the custodian’s management powers as a retained ability to alter the transfer.
The 2026 federal estate tax exemption is $15,000,000, so this matters only for larger estates at the federal level.7Internal Revenue Service. What’s New – Estate and Gift Tax State estate tax thresholds are often much lower. The fix is simple: if you are the donor, name someone else as custodian. A spouse, a grandparent, or a trusted sibling can serve and eliminate the risk.
Naming a Successor Custodian
A custodian can resign or become unable to serve because of death or incapacity. State statutes generally allow a custodian to designate a successor at any time by written instrument. If no successor has been named and the custodian dies or becomes incapacitated, most states follow a sequence: a minor who is at least 14 can designate a successor from among adult family members or a trust company; if the minor is younger than 14 or does not act, the minor’s legal guardian typically becomes the successor; if no guardian exists, an interested party can petition the court to appoint one.
Name a successor custodian when you open the account, and keep the designation current. Dying without one forces a family into court, and those costs come out of the child’s assets.
