What Is a Custodial Owned Annuity and How Does It Work?

A custodial-owned annuity is an insurance contract that an adult legally controls on behalf of a minor, who is the beneficial owner. The custodian signs the paperwork, directs the investments, and requests any withdrawals; the child’s Social Security number is tied to the account, and the child takes outright ownership when they reach the age of majority set by state law. These accounts are most often created through a gift under the Uniform Transfers to Minors Act, but they can also appear inside an IRA or 403(b) plan, and the tax rules differ depending on which track the annuity sits on.

The Three Parties and Who Controls What

A custodial annuity involves three distinct roles. The insurance company issues the contract. The custodian is the legal owner on the company’s books and makes every decision about the account. The minor is the beneficial owner and usually the annuitant, meaning the child’s life expectancy is what the contract’s payout math is built on.

That split between legal control and beneficial ownership is the entire point of the structure. The custodian manages the money so the child cannot squander it, but the custodian is not free to treat the funds as personal assets. Every dollar belongs to the child and must be used for the child’s benefit. When the child reaches the termination age, the custodian’s authority ends and the child becomes the direct owner of record.

How These Accounts Get Set Up

UTMA and UGMA Annuities

Most custodial annuities are opened under the Uniform Transfers to Minors Act or its older cousin, the Uniform Gifts to Minors Act. UTMA was written broadly enough to allow transfers of almost any kind of property, including annuity contracts, without creating a formal trust.¹ These are non-qualified annuities: the money going in is after-tax, and the account is not governed by retirement plan rules. The specific version of UTMA your state has adopted controls the details, including when the account must transfer to the child.

Custodial IRAs and 403(b) Annuities

A custodial annuity can also live inside a qualified retirement plan. A custodial IRA can be opened for a minor with earned income from a part-time job. A 403(b), available to employees of public schools and some tax-exempt employers, can hold annuity contracts or mutual-fund custodial accounts.² A child can also inherit a retirement annuity from a deceased parent, which triggers its own distribution timeline under federal law and sits outside the scope of a standard UTMA setup. Qualified accounts carry contribution limits, required distribution rules, and early-withdrawal penalties that differ from UTMA-based annuities, and the distinction matters most at tax time.

What the Custodian Can and Can’t Spend the Money On

The custodian is the only person who can act on the account while it is active. They choose the investment allocation, request withdrawals from the insurance company, and handle every form. The authority comes with a hard limit: it has to be spent for the child’s benefit.

Under UTMA, custodial property cannot be used for expenses that fall under a parent’s basic legal obligation of support.³ That restriction catches people off guard. A custodian can pay for a summer program, a car for the child, or college costs that go beyond basic support. The custodian cannot use withdrawals to cover groceries, rent, or the electric bill that the parent already owes the child as a matter of support. A custodian who dips into the account for personal use can be made to repay it, and courts have authority to impose additional remedies on top of reimbursement.

How It’s Taxed While the Money Stays Inside

Growth inside a custodial annuity is tax-deferred whether the account is qualified or non-qualified. No tax is owed on interest, dividends, or investment gains as long as the money stays in the contract. For non-qualified annuities, the deferral comes from IRC Section 72: amounts allocable to the investment in the contract are not included in gross income until withdrawn, and only the earnings portion is taxable at that point.⁴

One technical point is worth knowing. Section 72(u) strips tax deferral from annuities owned by entities rather than individuals, but it carves out trusts and other arrangements where someone holds title as an agent for a natural person. A custodial account qualifies for that carve-out because the custodian holds title on behalf of the child, so the deferral stays intact.⁴

How It’s Taxed When Money Comes Out

When money is pulled from a non-qualified custodial annuity, the IRS treats the withdrawal on a last-in, first-out basis. Every dollar of gain comes out before any of the original premium.⁴ Those earnings are taxed as ordinary income, not at capital gains rates. Once all of the earnings have been distributed, any remaining withdrawals of the original premium come out tax-free.

The reporting runs through the child. Distributions appear on Form 1099-R, which the insurance company is required to issue for any distribution of $10 or more, and the income goes on the child’s return under the child’s Social Security number.⁵

The kiddie tax can also apply. For 2026, a child’s unearned income above $2,700 is taxed at the parent’s marginal rate. The first $1,350 is sheltered by the child’s standard deduction, the next $1,350 is taxed at the child’s own rate, and anything above $2,700 is taxed at the parent’s rate.⁶ The kiddie tax reaches children under 18, 18-year-olds who do not earn more than half their own support, and full-time students aged 19 through 23 who do not earn more than half their own support. If it applies, Form 8615 is filed with the child’s return.⁷ Because the annuity grows tax-deferred, the kiddie tax typically only matters in years when a distribution is actually taken.

The Early Withdrawal Penalty Problem

A 10% penalty applies to early distributions from a custodial annuity, but which code section controls depends on the type of account.

For non-qualified annuities, which covers most UTMA custodial annuities, the penalty comes from IRC Section 72(q) and applies to the taxable portion of any distribution taken before age 59½.⁴ Exceptions include distributions made after the holder’s death, distributions due to disability, and substantially equal periodic payments spread over life expectancy.

For custodial IRAs and 403(b) annuities, the penalty comes from IRC Section 72(t), with its own set of exceptions, including certain medical expenses and birth or adoption distributions up to $5,000 per child.⁸ The two penalty sections are mutually exclusive.

The practical issue for a custodial annuity is the age gap. A child who takes control at 18 or 21 is decades away from 59½. Any withdrawal of earnings before that age triggers the 10% penalty unless an exception applies, which is a long lock-in that families should weigh before funding the account.

Gift Tax on Funding

Putting money into a UTMA custodial annuity is an irrevocable gift. The donor cannot take it back. For 2026, a donor can give up to $19,000 per recipient without filing a gift tax return or using any lifetime exemption.⁹ Married couples who split gifts can contribute up to $38,000 per child per year. Contributions above the annual exclusion require Form 709 and count against the donor’s lifetime exemption, though no actual gift tax is owed until that lifetime cap runs out.

Families sometimes fund one of these annuities with a single large premium. If the premium exceeds $19,000, the overage is a taxable gift. Splitting the contribution across calendar years or between spouses avoids that for most families.

What Happens When the Child Reaches the Age of Majority

The custodial relationship ends by law when the beneficiary reaches the termination age. That age varies by state. Most states use 18 or 21, and several states, including Oregon, Washington, and Alaska, allow the original donor to extend the custodial period to age 25 if that election is made when the account is created.¹⁰ The termination age is fixed by state law and by the terms chosen at the start, not by the custodian’s later preference.

At termination, the custodian must transfer full ownership. The insurance company processes a change-of-ownership form, the custodian comes off the account, and the former minor has total control. From that moment, the new owner can surrender the contract, change beneficiary designations, or leave the annuity alone to keep growing tax-deferred.

This is the point many families underestimate. Once the child reaches the termination age, the money is theirs outright with no strings. An 18-year-old who takes over a $100,000 annuity can surrender it and spend the proceeds on anything. A donor who wants to maintain control past the age of majority needed a formal trust with discretionary distribution provisions, not a custodial account.

If the Custodian Dies or Steps Down

UTMA has a successor process. The original custodian can name a successor in advance by written designation or in their will. If no successor was named, most states let a minor who has reached 14 designate a successor from among adult family members, the minor’s guardian, or a trust company. If the minor is too young to act, the guardian steps in, and if there is no guardian, an interested person can petition a court.

The practical move is to name a successor in writing when the account is set up. Falling back on the statutory process means court involvement, delays, and legal fees that come out of the child’s assets.

FAFSA Treatment

Custodial annuities sit in an unusual spot for financial aid. The FAFSA excludes the value of annuities when calculating a family’s assets, grouping them with retirement plans and life insurance.¹¹ UTMA and UGMA accounts, meanwhile, are specifically listed as reportable investments and are counted as the student’s assets, which are assessed at a higher rate than parental assets.

The FAFSA instructions do not directly address the overlap when a UTMA account holds an annuity. In practice, if the general annuity exclusion applies, a custodial annuity may be more aid-friendly than a custodial brokerage account holding stocks or mutual funds. Families should run this past a financial aid advisor before filing, because misreporting assets can trigger verification and delay the award.
