The Uniform Gifts to Minors Act lets you move cash or securities to a child through a custodial account without setting up a trust or hiring a lawyer. The account is registered in the child’s name, so the child legally owns every dollar from the moment you deposit it. An adult custodian manages the investments until the child reaches the age of majority under state law, and then the child takes full, unrestricted control. The structure is simple, but the tax treatment, financial aid impact, and that mandatory handover at adulthood all deserve a careful look before you fund one.
How a UGMA Account Is Structured
Three roles are involved: a donor who contributes the money, a custodian who manages it, and the minor who owns it. Most brokerages and banks will open the account with standard paperwork. The gift is irrevocable. Once the money lands in the account, the donor cannot pull it back, redirect it to another child, or reclaim it if circumstances change.
The custodian can be the donor, a parent, another trusted adult, or a financial institution. Whoever takes the role is legally responsible until the child reaches the termination age set by state law. Naming yourself as both donor and custodian creates an estate tax risk covered below, and it is easy to avoid by picking someone else.
The account title follows a specific format that signals the custodial relationship: “[Custodian Name] as Custodian for [Minor Name] under the [State] Uniform Gifts to Minors Act.”1FINRA. FINRA Reminds Member Firms of Their Responsibilities for Supervising UTMA and UGMA Accounts That titling keeps the assets legally separated from both the custodian’s personal property and the donor’s estate.
UGMA accounts are limited to financial assets: cash, bank deposits, publicly traded stocks and bonds, mutual funds, and insurance or annuity contracts. Real estate, fine art, patents, and other non-financial property cannot be held in a UGMA.
What the Custodian Can and Cannot Do
The custodian is a fiduciary. In plain terms, the law holds them to a “prudent person” standard: invest the child’s money with the same care a reasonable person would use managing someone else’s property. Parking everything in a single speculative stock would likely violate that duty. Age-appropriate diversification is the safer path.
Spending from the account is allowed only for the child’s direct benefit, such as tutoring, summer camp, a musical instrument, or similar enrichment. What the custodian cannot do is use the account to cover basic necessities like groceries, housing, or everyday clothing. Those fall under a parent’s existing legal obligation to support their child. Substituting custodial funds for expenses you already owe as a parent crosses the line, and the child can challenge those withdrawals after reaching adulthood.
Custodians are entitled to reasonable compensation, though most family custodians don’t charge anything. Keep records of every transaction, dividend, and expense. Those records feed into the child’s tax return and will matter if anyone later questions how the money was spent.
Taxes on a UGMA Account
UGMA accounts sit at the intersection of three federal tax rules: income tax on the account’s earnings, gift tax on the original contribution, and estate tax if the donor also serves as custodian.
Kiddie Tax on Investment Earnings
Every dollar of interest, dividends, and capital gains is legally the child’s income, reported under the child’s Social Security number. But children don’t get a free pass. The “kiddie tax” rules apply to unearned income of any child under 18, plus 18-year-olds and full-time students under 24 whose earned income doesn’t cover more than half their own support.2Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax)
For 2026, the math works in three tiers:3Internal Revenue Service. Rev. Proc. 2025-32
- The first $1,350 is tax-free, matching the standard deduction for a dependent with only unearned income.
- The next $1,350 is taxed at the child’s own rate, which is 10% for most children.
- Anything above $2,700 is taxed at the parents’ marginal rate, which can be substantially higher.
That third tier is where the kiddie tax actually bites. A child with $10,000 in UGMA dividends is not paying a child-sized tax bill on the amount above $2,700; the IRS treats it as if the parents earned it. The child files their own return using Form 8615 to calculate the tax.4Internal Revenue Service. 2025 Instructions for Form 8615 – Tax for Certain Children Who Have Unearned Income
If the child’s gross income is more than $1,350 but less than $13,500 for 2026, parents can elect to report the child’s unearned income on their own return using Form 8814 instead of filing a separate return for the child.3Internal Revenue Service. Rev. Proc. 2025-32 It simplifies paperwork and may slightly raise the parents’ tax bill by pushing adjusted gross income higher.
Gift Tax on Contributions
Funding a UGMA account is a completed gift the moment the money goes in. For 2026, the annual federal gift tax exclusion is $19,000 per donor per recipient.5Internal Revenue Service. Frequently Asked Questions on Gift Taxes A married couple can split gifts and contribute up to $38,000 to one child’s UGMA in a single year without any gift tax consequences.
Contributions within the annual exclusion require no IRS paperwork. If you exceed it, file Form 709 to report the gift. The excess doesn’t necessarily trigger a tax bill right away; it chips away at your lifetime gift and estate tax exemption, which for 2026 is $15 million per person under recently enacted legislation. Only after you exhaust that lifetime amount would actual gift tax be owed.6Office of the Law Revision Counsel. 26 U.S.C. 2503 – Taxable Gifts
The Estate Tax Trap for Donor-Custodians
Because a UGMA contribution is irrevocable, the account’s value normally stays out of the donor’s taxable estate. The exception is when the donor is also the custodian. If a donor-custodian dies before the child reaches the age of majority, the IRS can pull the entire account balance back into the donor’s gross estate under Internal Revenue Code Section 2038.7Office of the Law Revision Counsel. 26 U.S.C. 2038 – Revocable Transfers A custodian’s power to decide how and when to spend the money on the child’s behalf is treated as a retained power to change who benefits from the gift.8eCFR. 26 CFR 20.2038-1 – Revocable Transfers
The fix is straightforward: name someone other than the donor as custodian. A spouse, grandparent, or other trusted adult eliminates this risk. For most families the $15 million exemption means estate tax won’t apply regardless, but anyone with a larger estate should take this step seriously.
How a UGMA Affects Financial Aid
This is where UGMA accounts catch many families off guard. On the FAFSA, a UGMA is reported as the student’s asset, not the parents’, because the child is the legal owner. The federal financial aid formula assesses student assets at 20% when calculating the Student Aid Index, so one-fifth of the account balance is treated as money available to pay for college each year.9Federal Student Aid. Student Aid Index (SAI) and Pell Grant Eligibility – 2025-2026 FSA Handbook
Parental assets, by contrast, are assessed at a maximum of 12% after protection allowances that shield a portion of parental savings entirely. The practical difference is real: a $50,000 UGMA account reduces financial aid eligibility by $10,000 per year, while $50,000 held in a parent’s name would reduce it by considerably less.
Any interest, dividends, or capital gains from the UGMA that show up on the student’s tax return also count as student income on the FAFSA, which is assessed at an even steeper rate. Families planning to apply for need-based aid should weigh this cost before funding a large custodial account. A 529 college savings plan, reported as a parental asset for dependent students even when owned by the student, often produces a better financial aid outcome.
When the Child Takes Over
UGMA accounts terminate automatically when the child reaches the age of majority set by their state’s statute, which is 18 in most states and 21 in others.10Social Security Administration. POMS SI 01120.205 – Uniform Transfers to Minors Act No grace period, no extension, no discretion. The custodian must retitle all securities and bank accounts into the adult’s name and hand over complete control.
The new adult can then spend the money on anything. If the account was meant for college but the 18-year-old wants a car or a gap year, that is their legal right. The donor and custodian have no mechanism to restrict, delay, or redirect the funds once the termination age arrives. This no-strings handover is the single biggest drawback of the UGMA structure, and it is the reason many families consider alternatives like 529 plans or formal trusts.
Creditor Protection
Because the child is the legal owner from the moment assets enter the account, the donor’s and custodian’s personal creditors generally cannot reach the money. If the custodian files for bankruptcy, the UGMA account should not be part of the bankruptcy estate, because the custodian never owned the assets.
Two limits apply. If a donor transferred money into a UGMA shortly before creditors came calling, a court could treat the transfer as fraudulent and claw it back. And the money is exposed to the child’s own creditors: if the minor, or the adult the minor becomes, incurs debts or legal judgments, the account is fair game.
UGMA vs. UTMA
The Uniform Transfers to Minors Act (UTMA) is the modern successor to the UGMA, adopted in some form by nearly every state. Two differences matter most: asset scope and termination flexibility.
A UGMA account can only hold financial assets like cash, stocks, bonds, mutual funds, and insurance contracts. A UTMA account can hold virtually any type of property, including real estate, fine art, royalties, and patents. If you want to gift something other than traditional investments, UTMA is the only custodial-account option that fits.11Legal Information Institute. Uniform Gifts to Minors Act (UGMA)
Termination age is the other major difference. UGMA accounts end at 18 or 21 depending on the state, with no option to extend. UTMA accounts in many states allow the donor to specify a later termination age, up to 25 in some jurisdictions.12Social Security Administration. POMS SI SEA01120.205 – The Legal Age of Majority for Uniform Transfer to Minors Act (UTMA) That extra time can matter for families worried about handing a large sum to an 18-year-old. If your state offers UTMA accounts and you haven’t opened a custodial account yet, UTMA is almost always the better choice. Existing UGMA accounts remain governed by the original act and cannot simply be converted.
