Custodial Roth IRA for Minors: Earned Income Rules

A Roth IRA for minors can be opened and funded by a parent once the child has earned income—even a few hundred dollars from a summer job or babysitting. Contributions and growth are tax-free, and the minor controls the account at adulthood, making it a powerful long-term wealth-building tool.

The Earned Income Requirement

The IRS requires that any deposit into a Roth IRA come from earned income. A minor cannot fund an account with investment returns, an inheritance, or an allowance—there must be real W-2 wages or self-employment income behind it.

This is where many families miss an opportunity. A thirteen-year-old working a paper route, a sixteen-year-old at a fast-food restaurant, a college student freelancing as a social-media consultant—all have earned income and all qualify.

W-2 wages are straightforward: the child works for an employer, receives a W-2 form, and the income is documented. Self-employment income counts too. A teenager selling crafts on Etsy, mowing lawns, tutoring peers, or writing a freelance article has self-employment income and can fund a Roth, subject to the Schedule C deduction for business expenses.

One small note: a parent can employ their child in a family business and pay them a reasonable wage for real work. This is legal and common, and the child’s earnings qualify for a Roth contribution.

Contribution Limits and the Earned Income Cap

The IRS caps Roth contributions at either:

1. The annual IRA limit ($7,000 in 2025, though this typically rises with inflation), or
2. The minor’s total earned income that year

whichever is smaller.

A twelve-year-old who earns $2,000 from a summer job can contribute up to $2,000 to a Roth—not the full annual limit. A college student earning $15,000 part-time can contribute the full annual limit, capped at her total earned income.

This is where the power emerges. Even a modest early contribution grows tax-free for decades. A $2,000 Roth contribution at age fourteen, growing at 8% annually (a long-term stock market average), reaches roughly $115,000 by age sixty-five—all tax-free.

Who Opens and Manages the Account

A minor cannot legally open their own brokerage account or IRA. A parent or legal guardian must establish a custodial Roth IRA on the child’s behalf. The custodian holds legal title and makes investment decisions—though responsible parents involve their children in those choices.

Investment options inside the custodial Roth are the same as a regular Roth: stocks, bonds, mutual funds, ETFs, or target-date funds. Many families choose a low-cost, diversified index fund to avoid market-timing risk and teach the child a buy-and-hold mentality.

The custodian also handles administrative tasks: tracking contributions, filing tax forms, and managing the account until the child reaches the age of majority (eighteen or twenty-one, depending on state law). At that age, ownership transfers to the young adult.

Tax Treatment and Withdrawal Rules

Because Roth contributions are made with after-tax dollars, there’s no tax deduction in the year of contribution. The parent cannot offset earned income with the Roth deposit—this is different from a traditional IRA or 401k plan.

However, the trade-off is immense: all growth is tax-free. Dividends, capital gains, interest—none of it is taxed as long as money stays in the Roth. On withdrawal after age 59½ (and provided the account has been open at least five years), the entire balance comes out tax-free.

A unique advantage: contributions (not growth) can be withdrawn anytime, penalty-free. If a minor needs money for a genuine emergency before retirement, they can withdraw what they put in, though this should be a last resort since the tax-free growth is the real prize.

Catch-Up Contributions and Income Phase-Out

A minor with earned income has no income limits on Roth contributions—this is one advantage of age. Income phase-outs that affect adults don’t apply.

As the child grows and earns more, they can max out their Roth every year. A high-school student working full-time during summer could contribute $7,000. A college student with part-time wages could do the same. The earlier the contribution happens, the longer it compounds.

Practical Example

Imagine a sixteen-year-old earns $3,500 working retail during the school year. The parent opens a custodial Roth IRA and contributes $3,500 (the full earned income, below the annual limit). The parent invests it in a total-market index fund.

Ten years later, at age twenty-six, the account has grown to roughly $6,000 (assuming 5% annual returns). The young adult rolls the custodial Roth into their own Roth IRA and continues building wealth. By sixty-five, that $3,500 initial contribution could exceed $100,000—all tax-free.

Compare this to a teenager with earned income who doesn’t fund a Roth: that same $3,500, if invested in a taxable brokerage account, would owe taxes on dividends and gains every year, shrinking the final balance by 20–30% or more.

State Custodianship Laws and Transitions

Custodianship rules vary by state. Most end when the minor reaches eighteen; a few extend to twenty-one. Once the minor matures into an adult, the custodial Roth automatically becomes theirs. Some brokerages require paperwork to formalize the transition; others do it seamlessly.

If the custodian (parent) passes away, the account passes to the minor as a beneficiary—the estate tax is not triggered because custodial accounts are typically outside the parent’s taxable estate.

The Compound Interest Case for Early Savings

The most compelling argument for a custodial Roth is time. A dollar invested at age fourteen has fifty years to compound. A dollar invested at age twenty-four has forty years. Over decades, this difference is enormous.

Even families with limited discretionary income can teach their children the Roth habit by funding a small contribution each year. A fifteen-year-old who works and contributes $500 annually for five years ($2,500 total) locks in decades of tax-free growth—a habit that, reinforced, can reshape a lifetime of finances.
