Custodial Roth IRA

A custodial Roth IRA lets a minor with earned income build retirement savings, with a parent or guardian as custodian. Contributions are capped at the lesser of $7,500 (the 2026 Roth limit) or the minor's earned income for the year. The minor owns the account; control transfers at the state's age of majority (18 or 21). Decades of tax-free compounding can turn modest teen contributions into seven figures.

What Is a Custodial Roth IRA?

A custodial Roth IRA is a standard Roth IRA opened in a minor's name, with a parent, guardian, or other adult as the legal custodian until the child reaches the age of majority. The account itself is no different from an adult's Roth IRA—same rules, same tax treatment, same investments available. The only distinction is legal: the minor owns the account, but the custodian has control until the account transitions to the minor at the age of majority.

After the age of majority (age 18 in most states, age 21 in some states like Alabama and Nebraska), the custodian's role typically ends. The account becomes the young adult's to control, though some custodians allow for UTMA/UGMA (Uniform Transfers to Minors Act) provisions that allow the custodian to retain control until age 25. You'll want to clarify this when opening the account.

Earned Income Requirement

The minor must have legitimate earned income. This includes W-2 wages from an employer, net self-employment income, or modeling/acting income reported on Schedule C or as 1099 compensation. It does NOT include allowance, gifts, investment income, or parental support.

Common sources of earned income for minors: summer jobs, part-time employment (mowing lawns, babysitting, tutoring), newspaper routes, self-employment (selling crafts online, freelance writing), family business employment (paid by parents' business for actual work), and entertainment/modeling income.

The IRS requires documentation of earned income. Keep your minor's W-2s, 1099s, Schedule C (for self-employment), or other proof of income. If audited, the IRS will verify that the minor actually earned the amount claimed and that the contribution doesn't exceed that earned income.

Contribution Limits for Custodial Roth IRAs

The annual contribution limit for a custodial Roth IRA is the lesser of $7,500 (for 2026) or the minor's earned income for that year. If a 14-year-old earned $4,000 babysitting, they can contribute $4,000 to their Roth—not the full $7,500.

The contribution comes from the minor's earned income, not from parental funds. However, parents can gift the money to the child to fund the contribution, and the child then deposits it into their account. This is common: a parent might say, "I'll match your summer job earnings dollar-for-dollar into your Roth," which effectively doubles the annual contribution through parental gifts.

The Compound Growth Advantage of Starting Early

The real advantage of a custodial Roth IRA is starting the 5-year clock and the compound growth clock decades before traditional retirement savings begin. Consider the math: from age 16 to 22 (7 years), consistent $7,500/year contributions total $52,500. From age 22 onward, assume no additional contributions and 7% annual growth (a reasonable long-term market average).

At age 65, that $52,500 has grown to approximately $1.19 million (FV of 7 annual $7,500 contributions compounded at 7% through age 65). This is entirely from investments made before age 23. Compare this to starting a Roth at age 30 with the same discipline ($7,500/year from 30-36, totaling $52,500), which grows to only about $462,000 by age 65. Starting at 22 rather than 30 creates an additional ~$728,000 in wealth through nothing but the passage of time and compound interest. (If you assume an 8% long-run return instead of 7%, the age-22 figure rises to roughly $1.83 million; results are highly sensitive to the assumed return.)

This is why custodial Roths are often called the greatest wealth-building tool for families. The minor gets a head start that their peers won't match until decades into their careers.

The 5-Year Rule Advantage: Starting Early

For a custodial Roth IRA, the 5-year rule clock starts on January 1 of the tax year of the first contribution. This means a contribution made by a 16-year-old in 2026 starts the clock on January 1, 2026. By the time that person turns 65 (age 49 later), the 5-year rule will have been satisfied for decades.

This is unique to Roth IRAs opened in youth. Someone opening their first Roth at age 50 doesn't fully satisfy the 5-year rule until age 55. A minor opening a custodial Roth at 16 satisfies it by age 21. All subsequent Roth growth and withdrawals after age 59½ will be completely tax-free with no 5-year restriction complications.

Parental Control, Transition at Age of Majority

The parent or guardian serves as the legal custodian until the age of majority. This means the custodian typically approves contributions, controls investment directions, and manages the account. The minor cannot unilaterally withdraw funds (though some custodians allow minor-directed accounts with parental oversight).

At the age of majority (18 or 21, depending on state, or in some cases 25 if the account is under UTMA/UGMA), the account transitions to the young adult's control. The parent loses custodial rights. From that point forward, the young adult can invest, direct, and withdraw from their account according to standard Roth IRA rules.

This transition is automatic with most custodians. The young adult receives login credentials and can take full control. There's no tax event upon transition—it's purely a legal change of control.

Tax Filing and Reporting

When a minor has earned income and contributes to a custodial Roth IRA, both the income and the Roth contribution must be reported on the minor's tax return (if required by their income level). A minor can typically be claimed as a dependent on their parent's return if they meet the dependency test, even if they file their own return for Roth contribution purposes.

The parent should file Form 5498 (IRA Contribution Information) and/or coordinate with the custodian to ensure the contribution is properly reported. Some custodians handle this automatically; others require the parent to provide the minor's Social Security number and address.

If the minor has other types of income (W-2 wages from a job), they may need to file a full Form 1040 even if their income is below the standard deduction. Consult a tax professional if the minor has multiple income sources.

The "Legitimate Services Actually Performed" Standard: What the IRS Actually Checks

The IRS's bar for child earned income is that services were actually performed, were age-appropriate, and were compensated at a reasonable rate. This standard comes from a line of Tax Court cases most notably Eller v. Commissioner, 77 T.C. 934 (1981), and Denman v. Commissioner, T.C. Memo 1992-586. The IRS position has been further articulated in audit guides that examine family business employment of children with unusual scrutiny.

The three failure modes that trigger disallowance:

1. Age-inappropriate work. A 4-year-old "earning" $7,500 as a "model" for the family business Instagram account has been repeatedly rejected by the Tax Court. A 10-year-old doing legitimate filing, shredding, or running simple errands for a home-based business is typically accepted. A 14-year-old doing actual bookkeeping or graphic design is generally unquestioned. The rule of thumb: a stranger's child at the same age could do the same work.

2. Unreasonable compensation. Paying a 10-year-old $50/hour to stuff envelopes fails the "reasonable rate" test. The IRS uses Bureau of Labor Statistics wage data for comparable work performed by adults as a benchmark. A child doing genuine work at federal minimum wage ($7.25) or slightly above is usually defensible. A child paid triple the market rate is not.

3. No time records. Without contemporaneous records showing hours worked, tasks performed, and amounts paid, the IRS presumption (in audit) is that the income wasn't earned. A simple spreadsheet kept throughout the year, supplemented by check stubs or W-2/1099 filings, is usually sufficient.

For parents paying their own children from a family business: if the business is a sole proprietorship or a partnership where only the child's parents are partners, wages paid to a child under 18 are exempt from FICA and FUTA under IRC §3121(b)(3)(A) and 3306(c)(5). This means the business owes no payroll tax, and the child pays no payroll tax either—they keep the full amount. For S-corporations, no such exemption; payroll tax applies.

The Kiddie Tax and Roth Earnings: Why Roth Is the Perfect Shelter

IRC §1(g) (the "kiddie tax") taxes unearned income of a child under 18 (or under 24 if a student) at the parent's marginal rate, once it exceeds $2,700 in 2026 (2 × $1,350 per Rev. Proc. 2025-32 §4.02: first $1,350 is offset by the child's standard deduction under §63(c)(5)(A); next $1,350 is taxed at the child's rate; amounts above $2,700 are taxed at the parent's marginal rate). A child earning $10,000 in dividends from a taxable brokerage account could see the top $7,300 taxed at the parent's 32% rate instead of the child's 10%. For affluent families saving for children outside a tax-advantaged account, the kiddie tax is a major drag.

Roth IRAs sidestep the kiddie tax entirely. Earnings inside the Roth are never taxed—not to the child, not to the parent. When the child eventually withdraws earnings (after meeting the 5-year rule and age 59½ for qualification, or via an exception), the withdrawal is tax-free. For dividend-heavy or high-growth investing aimed at a child's long-term wealth, a custodial Roth is strictly superior to a UTMA/UGMA account on tax grounds. UTMA/UGMA remain useful for funds the child will need before age 59½ for non-exception purposes, but for retirement-horizon investing the custodial Roth wins on every dimension.

UTMA/UGMA Conversion to Custodial Roth: a Nuanced Path

Money held in a UTMA (Uniform Transfers to Minors Act) or UGMA (Uniform Gifts to Minors Act) account is legally the child's property. If the child has earned income, the parent can direct funds from the UTMA to the child's custodial Roth IRA contribution, up to the child's earned income (and the $7,500 annual cap). This shifts money from a kiddie-tax-exposed account to a fully tax-advantaged account without gift tax implications (the money was already the child's).

Practical constraint: UTMA/UGMA accounts are typically held at brokerages that treat the child as the account owner. Funding a separate custodial Roth IRA may require a distribution from the UTMA and a transfer to the Roth. Some custodians (Fidelity, Schwab) permit in-kind transfers between UTMA and custodial Roth without liquidating positions—particularly valuable if the UTMA holds long-term appreciated equities.

FAFSA and Financial Aid: Custodial Roth Is Treated Favorably

The Free Application for Federal Student Aid (FAFSA) asks about student and parent assets. Retirement accounts (including Roth IRAs, 401(k)s, etc.) are excluded from assessable assets—they are not reported as student or parent assets on the FAFSA (since the 2023-24 simplified FAFSA took effect under the FAFSA Simplification Act of 2020). This is a critical advantage over UTMA/UGMA accounts, which count as student assets at a 20% rate for financial aid purposes. A $50,000 UTMA reduces need-based aid by $10,000; a $50,000 custodial Roth reduces need-based aid by $0.

There is a narrow caveat: withdrawals from a Roth IRA during college years (e.g., to fund tuition under the education exception) are counted as student income on the subsequent FAFSA, with a 50% assessment rate. This is why the recommendation for college funding is usually: don't touch the Roth during college years if need-based aid is in play. Withdrawals can wait until after the last FAFSA filing (generally the student's final undergraduate year). Or use 529 funds for college and let the Roth compound for retirement.

Documenting Earned Income

The IRS takes the earned income requirement seriously. For W-2 employment, the W-2 itself is sufficient proof. For self-employment (babysitting, lawn mowing), keep records of customers paid, dates of service, and amounts received. For family business employment, keep timesheets and documentation that the minor actually performed the work (the IRS watches for "sham" employment where parents claim their children earned income they didn't).

If audited, you'll need to prove: (1) the minor had earned income, (2) the amount was as claimed, (3) the contribution didn't exceed the earned income, and (4) the account was properly established as a custodial Roth IRA. Keeping organized records of income documentation prevents IRS trouble.
