What Is a Custodial IRA? Rules, Limits, and Contributions

A custodial IRA is a retirement account an adult opens and manages for a minor who has earned income. The child owns the money from the moment it lands in the account, but a parent, grandparent, or other adult acts as custodian and makes the investment decisions until the child reaches the age of majority under state law. Because the account follows the same federal tax rules as any other IRA, it gives a young earner decades of tax-advantaged growth on money they might otherwise spend or park in a checking account.

How the Account Is Structured

Two people are named on a custodial IRA. The minor is the owner; the adult is the custodian authorized to manage it. Federal tax law treats the custodian as the trustee for tax purposes, so the arrangement carries the same legal weight as a standard IRA.¹

The custodian has a fiduciary duty. Every investment choice has to serve the child’s interest, not the adult’s. Contributions are irrevocable: once money enters the account, the adult cannot take it back for personal use. The structure draws on state-level Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA) frameworks, which let adults hold property on behalf of a minor without setting up a formal trust.

The Earned Income Requirement

Nothing else about a custodial IRA matters if this rule isn’t met. The minor must have earned income during the tax year a contribution is made, and the contribution cannot exceed that income.² If your child earns $2,000 from a summer job, the ceiling for the year is $2,000. If they earn $10,000, the annual contribution limit kicks in as the ceiling instead.

Wages, salary, tips, and net self-employment earnings all count. A teenager working retail, mowing lawns for pay, or freelancing as a graphic designer qualifies. Allowances, gifts, and investment returns do not.²

Documenting the Income

A W-2 from a formal employer settles the question. Informal work needs more care. Keep a log of dates worked, hours, tasks, who paid the child, and how much. The IRS has no special form for a minor’s earned income, but detailed records protect the contribution if it’s ever questioned. Depositing payments into the child’s bank account creates a paper trail worth having.

2026 Contribution Limits and Deadlines

For the 2026 tax year, the maximum IRA contribution for anyone under 50 is $7,500. The actual limit for a custodial account is the lesser of $7,500 or the child’s total earned income for the year.³

Contributions for the 2026 tax year can be made any time from January 1, 2026 through the federal filing deadline of April 15, 2027. That window lets you wait until the child’s earnings are finalized before making the deposit.

An over-contribution triggers a 6% excise tax on the excess for every year it stays in the account. To avoid the penalty, withdraw the excess plus any earnings it produced before the filing deadline, including extensions.³

Who Can Put the Money In

The dollars deposited don’t have to come from the child. A parent, grandparent, or anyone else can write the check. The only requirement is that the child earned at least as much as the contribution amount during the tax year.³

So if your 15-year-old earns $4,000 at a part-time job, you can deposit $4,000 of your own money into their custodial IRA and let them keep their paycheck for spending. The statutory requirement is compensation, not the specific dollars earned.²

Roth or Traditional

Most custodial IRAs are opened as Roths, and the math is why. A Traditional IRA gives you a deduction now and taxes withdrawals later. A Roth takes after-tax money now, grows tax-free, and pays out tax-free in retirement.

Working minors usually earn modestly enough that their income falls under the federal standard deduction, so they owe little or no income tax. A deduction is worth almost nothing when the tax bill is already zero. A Roth locks in that zero rate and lets decades of growth compound tax-free. Roth IRAs also carry no required minimum distributions, so the account can keep growing untouched for the child’s whole life. Roth income limits start at $153,000 in modified adjusted gross income for single filers in 2026, a threshold no working minor is going to hit.

Opening and Funding the Account

Most major brokerages and banks offer custodial IRAs online. The application looks like any IRA application with fields added for the minor.

You’ll need the minor’s Social Security number, since the child is the account owner for tax purposes; a government-issued ID for the custodian; and documentation of the child’s earnings (a W-2, a 1099, or your own detailed records for self-employment). The application asks whether the account will be a Roth or a Traditional. Once it’s approved, the custodian funds it by electronic transfer from a linked bank account, up to the child’s earned income for the year, and picks investments through the brokerage’s platform.

Getting Money Out

Money in the account is meant for retirement, and federal rules push it that way, but a Roth’s ordering rule gives families more flexibility than most retirement accounts do.

Contributions Come Out First

When a Roth IRA pays out, the IRS treats the withdrawal as coming from contributions first, then conversions, then earnings.⁴ Because contributions were made with after-tax money, withdrawals up to the total contributed are always tax-free and penalty-free, at any age, no matter how long the account has been open. That’s a real safety net if the child ever needs the cash.

Earnings are the harder part. Take them out before age 59½ or before the account has been open five years, and they’re subject to income tax plus a 10% additional tax.⁵

Exceptions to the 10% Penalty

Several situations waive the additional tax on early distributions of earnings:

Qualified higher education expenses, including tuition, fees, books, and room and board.⁶
A first-time home purchase, up to $10,000 in earnings.⁷
Disability of the account holder.
A series of substantially equal periodic payments over the account holder’s life expectancy.

These waive the 10% additional tax only. Income tax on the earnings portion still applies unless the withdrawal meets both the age and five-year rules for a qualified distribution.

Financial Aid Treatment

The FAFSA excludes retirement plan balances, including IRAs, from its asset calculations, so a custodial IRA’s value doesn’t count against your child on the federal form. That’s a real advantage over a regular UTMA or UGMA brokerage account, which the FAFSA counts as the student’s asset and which can reduce aid eligibility.⁸

Some private colleges use the CSS Profile alongside or instead of the FAFSA. The CSS Profile does require reporting retirement account balances, and schools that use it may weigh those assets differently. If your child is applying to CSS Profile schools, check how each one treats retirement accounts.

When Control Transfers to the Child

The custodial arrangement ends when the minor reaches the age of majority under state law. The most common termination age is 21, though it ranges from 18 to 25 across states, and a few states allow extensions beyond that. The exact age depends on how the original transfer was structured and whether the state follows the UTMA or the UGMA.⁹

At that point, the custodian has to transfer full control. The brokerage provides paperwork to remove the custodian’s name and re-register the account in the former minor’s name alone. From then on, it’s a standard IRA. The new adult owner makes their own investment decisions, keeps contributing if they have earned income, or takes distributions under the same withdrawal rules that applied before. If the custodian doesn’t initiate the transfer on time, the now-adult beneficiary can request it directly through the financial institution’s compliance department.
