Custodial Roth IRAs for Minors: An Underused Retirement Tool

The Opportunity

If your child has earned income — from a summer job, babysitting, lifeguarding, modeling, lawn mowing, or any work — you can open a Roth IRA in their name and start them on what may be one of the most powerful long-term wealth-building strategies available. A dollar contributed to a Roth IRA at age 15 has roughly 50 years of tax-free compounding ahead of it before traditional retirement age. The math is remarkable, and the strategy is dramatically underused.

For parents who think long-term about their family’s financial future, a custodial Roth IRA can quietly set up a child for retirement decades before they would otherwise have started. This article focuses on the Roth IRA as a long-term retirement account, not as a college savings vehicle (529 plans are better suited for education).

How a Custodial Roth IRA Works

A custodial Roth IRA is a Roth IRA opened in a minor’s name and managed by an adult custodian (typically a parent or grandparent) until the child reaches the age of majority in their state (18 or 21, depending on the state). Once the child reaches that age, control of the account transfers to them. They become the legal owner with full authority over investments and withdrawals.

The rules are essentially the same as for any Roth IRA:

• Contributions are made with after-tax dollars (no tax deduction)
• Growth is tax-free
• Qualified withdrawals in retirement (age 59½, after the 5-year holding requirement) are tax-free
• Contributions (but not earnings) can be withdrawn at any time without taxes or penalties

The critical requirement: the minor must have earned income for the year a contribution is made.

The Earned Income Requirement

A Roth IRA contribution requires earned income — wages, self-employment income, or similar compensation for services. Investment income, gifts, and allowances do NOT count. Eligible sources for minors include:

• W-2 jobs (summer employment, after-school jobs, retail work)
• Self-employment income (babysitting, lawn mowing, dog walking, tutoring)
• Gig work or contract work
• Modeling, acting, or content creation income
• Wages from a family business (if structured properly)

Documentation matters. For W-2 work, the employer documentation is sufficient. For self-employment income — especially cash work like babysitting or lawn mowing — keep a written log of jobs performed, dates, and amounts. The IRS may request this if questioned.

How Much Can You Contribute?

The 2026 contribution limit for a custodial Roth IRA is the lesser of:

• $7,500 (the standard Roth IRA contribution limit), or
• The child’s total earned income for the year

For example:

• If your child earns $2,000 babysitting, you can contribute up to $2,000 to their Roth IRA
• If your child earns $4,500 from a summer job, you can contribute up to $4,500
• If your child earns $10,000 doing seasonal work, you can contribute up to the $7,500 annual limit

Who Funds the Account

A common misconception is that the child must use their own money. They don’t. Anyone can fund the Roth IRA on the child’s behalf — parents, grandparents, or other family members — as long as the total contribution doesn’t exceed the child’s earned income for the year.

In practice, this is how most custodial Roth IRAs are funded. The child earns the income from their job, but parents contribute the equivalent amount to the Roth IRA on their behalf. The child keeps their earnings; the parents seed the retirement account.

This is especially useful for matching arrangements. A parent might say: “If you earn $2,000 this summer, I’ll contribute $2,000 to your Roth IRA.” The child gets to keep their wages, and the parent funds the retirement account separately. Both sides win.

Why the Math Is So Powerful

The power of a custodial Roth IRA comes from compounding over an unusually long time horizon. Consider a hypothetical scenario:

A parent contributes $3,000 to their 15-year-old’s custodial Roth IRA each year for four summers (ages 15, 16, 17, 18), funded by the child’s part-time job earnings. Total contributions: $12,000.

That $12,000, invested in a diversified portfolio earning an average 7% annual return, compounds untouched until age 65. At retirement, that balance would be approximately $360,000 — all tax-free.

If the child continues to contribute throughout their working years, the numbers become much larger. Even a single $7,500 contribution at age 16, left untouched until age 65, would grow to roughly $215,000 at 7% returns.

The combination of decades of tax-free growth and decades of additional time the money has to compound is what makes this strategy uniquely powerful.

Considerations and Trade-Offs

Income taxes. Most minors have low or zero federal income tax liability because their earnings fall below the standard deduction (which is $16,100 for 2026). This means Roth contributions don’t lose meaningful tax savings — there’s nothing significant to deduct anyway. The Roth approach is particularly well-suited for this reason.

No tax filing required for low earners. If your child earns less than the standard deduction, they typically aren’t required to file a tax return. They can still make Roth IRA contributions; documentation of the earnings is what matters.

Access for non-retirement uses. While the account is intended for retirement, contributions can be withdrawn at any time without taxes or penalties (only earnings are restricted). For a first-time home purchase, up to $10,000 in earnings can also be withdrawn tax- and penalty-free after the 5-year holding period. This gives the strategy some flexibility for major life events.

Loss of control at age of majority. When the child reaches the age of majority (18 or 21, depending on state), the account becomes theirs entirely. They can make their own decisions — including withdrawing contributions to fund non-retirement purchases. Parents who want to maximize the long-term retirement benefit should think about how to instill the discipline to leave the money invested.

Financial aid implications. Retirement accounts generally don’t count as assets on the FAFSA, so a custodial Roth IRA won’t directly hurt financial aid eligibility — a meaningful advantage over UTMA/UGMA accounts.

The Takeaway

A custodial Roth IRA may be one of the most powerful long-term wealth-building tools available, but it’s dramatically underused. If your child has earned income from any source — a summer job, self-employment, modeling, or gig work — you can contribute up to the lesser of the child’s earned income or $7,500 in 2026. Parents can fund the account on the child’s behalf, allowing the child to keep their wages while still seeding decades of tax-free compounding. The strategy is particularly potent because minors typically pay little or no income tax, so the Roth structure costs almost nothing upfront. With 50+ years of tax-free growth ahead, even modest contributions can become significant retirement balances. Good documentation of the child’s earned income is essential, especially for self-employment income from informal work.
