When a UTMA account reaches the age of majority, the custodianship ends automatically and the beneficiary takes full, unrestricted control of every asset in the account.1Social Security Administration. POMS SI 01120.205 – Uniform Transfers to Minors Act That transfer happens as a matter of law on the triggering birthday, though the paperwork to re-title the account takes a few days of coordination with the financial institution. The bigger surprise for most new account owners is on the tax side: the Kiddie Tax can still apply, and the cost basis on gifted securities carries over from whoever contributed them, which can produce a much larger capital gains bill than expected the first time anything is sold.
When the Custodianship Actually Ends
The custodian must turn over all custodial property once the beneficiary reaches the termination age set by the state law governing the account. Under the model Uniform Transfers to Minors Act, that is the age of majority in the enacting state, usually 18 or 21.2Uniform Law Commission. Uniform Transfers to Minors Act (Revised) – Section 20 Termination of Custodianship About a dozen states let the original donor specify a later age, sometimes as late as 25, and at least one state allows deferral to 30. The age had to be set at the time of the gift. It cannot be changed later.
On that birthday, the custodian’s legal authority ends. No more trades, no more withdrawals, no more payments from the account. The beneficiary has an absolute right to every dollar and every security and can use the money for any purpose at all, including purposes the donor never intended. The financial institution restricts the custodian’s access once it confirms the beneficiary has hit the triggering age.
The applicable state is typically the one named when the account was first opened, so the original account agreement is the best place to confirm which termination age applies. If those documents are long gone, the brokerage or bank holding the account can usually tell you both the governing state and the age. Some firms notify beneficiaries automatically as the date approaches; others do not. If you think you are close, call the institution rather than waiting.
Moving the Account Into Your Own Name
The mechanics of converting a UTMA to an individual account are not complicated, but the institution will not do it on a phone call. You will need a government-issued photo ID, your Social Security number, and proof of age, usually a birth certificate. Having the original account number on hand helps.p>
The institution will provide a change-of-ownership or transfer-of-control form. You choose a new account type, typically a standard individual brokerage or savings account, and both the custodian and the beneficiary generally sign. For accounts holding securities, expect a Medallion Signature Guarantee rather than a regular notarization. That is a special stamp confirming the signer has authority to authorize a securities transfer, and it is only available through banks and brokerages that participate in a Medallion program. A standard notary will not do.
Many brokerages accept the paperwork through a secure online portal now, though some still want original documents by mail. Processing usually takes a few business days. Once it clears, the custodial account closes, the assets move to a new individual account in your name alone, and the former custodian’s access is permanently removed. Keep the closing statement or confirmation notice as your record of the transfer.
Taxes Do Not Reset on Your Birthday
After the transfer, you are solely responsible for reporting all dividends, interest, and capital gains the account generates. The institution will issue the usual forms under your Social Security number: 1099-INT for interest, 1099-DIV for dividends, 1099-B for sales.3Internal Revenue Service. Topic No. 553, Tax on a Childs Investment and Other Unearned Income In the year of the handoff, you may receive forms covering both the custodial period and the period after you took over.
The Kiddie Tax Can Outlast the Custodianship
This is where many families get caught. The Kiddie Tax under IRC §1(g) and the UTMA termination age are two separate rules that do not necessarily line up. You can take full control of a UTMA account at 18 or 21 and still be subject to the Kiddie Tax on unearned income above $2,700.3Internal Revenue Service. Topic No. 553, Tax on a Childs Investment and Other Unearned Income
The rule reaches three groups:4Office of the Law Revision Counsel. 26 USC 1(g) – Certain Unearned Income of Children Taxed as if Parents Income
- Anyone under 18, regardless of income or support.
- Anyone age 18 whose earned income does not exceed half of their own support for the year.
- Full-time students ages 19 through 23 whose earned income does not exceed half of their own support.
When the Kiddie Tax applies, unearned income above $2,700 is taxed at the parents’ marginal rate rather than yours. A 21-year-old college junior who just took over a UTMA account and sells appreciated stock can still owe taxes computed at a parent’s rate. The rule drops away once you turn 19 (if not a student) or 24 (if a full-time student), or whenever your earned income exceeds half your own support, whichever comes first.
Carryover Basis on Gifted Assets
Assets contributed to a UTMA are gifts, and gifts do not get a stepped-up basis the way inherited property does. Under IRC §1015, you inherit the donor’s original cost basis, meaning whatever they paid.5Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust If a parent bought stock for $5,000 fifteen years ago and put it in your UTMA, your basis is still $5,000 even if the shares are now worth $50,000.
That matters when you sell. On a $50,000 sale with a $5,000 carryover basis, you owe capital gains tax on $45,000 of gain. The 1099-B often arrives with a much bigger number than new owners are expecting. If records of the donor’s original purchase price are missing, the burden is on you as the taxpayer to substantiate basis, so track down any documentation the donor still has before you need it.
Financial Aid Still Treats It as Yours
UTMA assets land harder on the FAFSA than most families expect. The federal formula treats UTMA accounts as the student’s asset, not the parent’s, no matter who funded the account or whether the student is still claimed as a dependent.6Federal Student Aid. Current Net Worth of Investments, Including Real Estate Student assets are assessed at up to 20 percent in the expected family contribution formula, compared with roughly 5.6 percent for parent assets. A $100,000 UTMA balance can reduce aid eligibility by as much as $20,000 a year.
This treatment holds whether the account is still in custodial form or has already been moved into your individual name. Spending the account down right before applications can draw its own scrutiny, and there is no clean workaround. The money is yours and gets reported as yours.
If the Custodian Will Not Hand It Over
Custodians who stall or refuse are more common than you might think. Sometimes it is a parent who does not trust an 18-year-old with a six-figure balance. Sometimes the money is not there anymore. Either way, the law is on the beneficiary’s side: once you hit the termination age, the assets must be transferred.
You can petition a court to compel the transfer and to demand a formal accounting of every transaction the custodian made during the custodianship. If that accounting shows funds were spent on the custodian’s own expenses rather than for your benefit, that is a breach of fiduciary duty, and you can seek damages. Filing fees for these petitions generally run between $30 and $500 depending on the jurisdiction.
Timing matters. The statute of limitations for breach-of-fiduciary-duty claims varies by state, and it can be as short as two years from the wrongful act. If you suspect money was mismanaged, do not wait to talk to an attorney, especially where the balance was substantial.
If Someone Dies Before the Account Terminates
If the custodian dies first, a successor custodian takes over. Many account agreements let the original custodian name a successor in advance. If none was named, the surviving parent typically steps in; if neither route is available, a court appoints someone to serve until you reach the termination age.
If the beneficiary dies before the termination age, the account passes to the beneficiary’s estate, not back to the donor. The gift was irrevocable from day one. The assets are then distributed under the beneficiary’s will or, if there is none, under the state’s intestacy rules.
One estate wrinkle worth noting: when the donor is also serving as custodian and dies before the account terminates, the full value of the UTMA account may be pulled into the donor’s estate for federal estate tax purposes, because the donor retained effective control over the gifted assets. For large accounts, naming someone other than the donor as custodian avoids the problem.
