Your Kid Probably Qualifies for a Roth IRA — And Starting One Now Could Be Worth Over $1 Million

Here's a number that stops most parents in their tracks: a single $6,500 contribution to a Roth IRA for a 15-year-old, invested in a broad stock index fund earning a historical 10% average annual return, grows to approximately $488,000 by age 65 — completely tax-free. Contribute the maximum every year from age 15 to 18, and the account can clear $2 million before your child ever makes their own contribution as an adult.

No other account available to minors offers this combination of tax-free growth, tax-free withdrawals, and total flexibility. Not a 529 plan (restricted to education). Not a custodial brokerage account (taxable gains). Not a savings bond (capped returns). A Roth IRA is the single most powerful financial gift you can give a working child — and most families don't know it's available to them.

The catch? Your child needs earned income. But the definition of "earned income" is broader than most parents realize, and the strategy is simpler to execute than you might think.

Key Takeaways

• Any minor with earned income can have a Roth IRA — there is no minimum age requirement. If your 12-year-old earns $2,000 mowing lawns, they can contribute up to $2,000.
• The 2026 contribution limit is $7,000 (or total earned income, whichever is less). Your child doesn't need to contribute their own earnings — you can fund the account with your money as long as they earned at least that much.
• Contributions (not earnings) can be withdrawn anytime penalty-free and tax-free, making this less risky than parents fear.
• The compound growth advantage is staggering — a teenager's Roth IRA has 45-50+ years of tax-free compounding ahead of it, dwarfing what a 35-year-old starting fresh can accumulate.
• Custodial Roth IRAs convert to regular Roth IRAs at the age of majority (18 or 21, depending on your state), giving your child full control.

What Is a Custodial Roth IRA?

A custodial Roth IRA is a standard Roth IRA opened on behalf of a minor, with a parent or guardian acting as the custodian who manages the account until the child reaches the age of majority. The child is the account owner — it's their money, their Social Security number, their tax situation. The custodian simply has authority to make investment decisions and manage the account until the child is old enough to take over.

The IRS doesn't have a special "custodial Roth IRA" category. It's just a regular Roth IRA with a custodial arrangement required by the brokerage because the account owner is a minor. The same contribution limits, withdrawal rules, and tax treatment apply as any other Roth IRA.

Custodial Roth IRA vs. Custodial Brokerage Account (UGMA/UTMA)

Parents sometimes confuse custodial Roth IRAs with UGMA/UTMA custodial accounts. They're fundamentally different:

| Feature | Custodial Roth IRA | UGMA/UTMA Account | |---|---|---| | Tax treatment | Tax-free growth, tax-free qualified withdrawals | Subject to kiddie tax (unearned income over $2,500 taxed at parent's rate) | | Income requirement | Child must have earned income | No income requirement | | Contribution limit | $7,000 or earned income (whichever is less) in 2026 | No limit | | Withdrawal flexibility | Contributions out anytime tax-free; earnings subject to rules | No restrictions once child reaches majority | | Financial aid impact | Not reported as student asset on FAFSA | Counted as student asset (hurts aid eligibility) | | Control after majority | Child controls a retirement account (strong behavioral guardrails) | Child gets unrestricted access to cash |

For most families, a custodial Roth IRA is the superior long-term wealth-building vehicle — as long as the child has earned income.

The Earned Income Requirement: What Counts (and What Doesn't)

This is where most parents get stuck. The IRS requires that the child have "earned income" — compensation for work performed. The contribution limit for the year is the lesser of $7,000 (the 2026 limit) or the child's total earned income.

Income That Qualifies

• W-2 employment: Part-time jobs, summer jobs, restaurant work, retail, lifeguarding, camp counselor positions — anything where the employer issues a W-2.
• Self-employment income: Babysitting, lawn mowing, tutoring, pet sitting, selling crafts on Etsy, freelance graphic design, social media content creation, acting/modeling. This is reported on Schedule C.
• Family business employment: Your child can work for your business and receive reasonable compensation for legitimate work performed. This is one of the most common and powerful strategies (more on this below).

Income That Does NOT Qualify

• Allowance — this is a gift, not compensation for services
• Investment income — dividends, interest, capital gains
• Gifts or inheritances
• Scholarship or grant income
• Chore payments without a legitimate work arrangement

The Family Business Strategy

If you own a business (sole proprietorship, partnership, or LLC taxed as either), hiring your child is one of the cleanest ways to establish earned income. The IRS allows this as long as three conditions are met:

1. The work is legitimate — filing, data entry, cleaning, inventory, social media management, product photography, website testing. It must be real work the business actually needs done.
2. The compensation is reasonable — you can't pay your 13-year-old $50,000 for answering phones. Pay what you'd pay any other worker for the same task. $12-20/hour for age-appropriate work is generally defensible.
3. You keep records — timesheets, job descriptions, and payment records. Treat it like any other employment relationship.

Bonus for sole proprietors and spousal partnerships: If your child is under 18 and employed by a parent's sole proprietorship (or a partnership where both partners are the child's parents), the wages are exempt from Social Security and Medicare taxes (FICA). This means your child keeps more of their pay, and you deduct the wages as a business expense. It's a rare case where both sides benefit from the same transaction.

How to Open a Custodial Roth IRA: Step by Step

Step 1: Confirm Your Child Has Earned Income

Before opening the account, make sure your child has earned (or will earn) income this calendar year. You don't need to wait until they've earned the full amount — you can contribute throughout the year as long as total contributions don't exceed their total earned income for the year by December 31.

Step 2: Choose a Brokerage

Not every brokerage offers custodial Roth IRAs. Here are the major platforms that do as of 2026:

• Fidelity — No minimums, no account fees, strong selection of zero-expense-ratio index funds. Fidelity's Youth Account (for ages 13-17) even gives teens limited self-directed access.
• Charles Schwab — No minimums, custodial IRA available, solid index fund lineup.
• Vanguard — Offers custodial IRAs but historically requires phone setup rather than fully online enrollment.
• Interactive Brokers — Available for minors, strong platform for families who want broader investment options.

Fidelity and Schwab are the most streamlined for opening custodial Roth IRAs entirely online.

Step 3: Open the Account

You'll need:

• Your child's Social Security number
• Your identification (driver's license, SSN)
• The child's date of birth
• Your relationship to the child

The process takes about 10-15 minutes online. The account will be titled in the child's name with you listed as the custodian.

Step 4: Fund the Account

You can fund the account via bank transfer, check, or transfer from another account. Remember: you can contribute your own money. As long as your child earned at least as much as the contribution amount during the year, the IRS doesn't care whose dollars actually go into the account. Many parents fund the entire Roth IRA themselves and let the child keep their earnings for spending money.

Step 5: Invest the Money

Don't let the contribution sit in a money market fund. For a minor with decades of compounding ahead, a simple, aggressive allocation makes sense:

• Single-fund approach: 100% total U.S. stock market index fund (like VTI, FSKAX, or SWTSX)
• Two-fund approach: 80% total U.S. stock market + 20% total international stock market (like VXUS or FTIHX)
• Target-date fund: Select a target-date fund for the year your child turns 65 (e.g., a 2075 or 2080 target-date fund)

At this time horizon, bonds and conservative allocations actively hurt long-term growth. A 100% equity allocation is appropriate for money that won't be touched for 45+ years.

The Math: Why Starting Young Is So Powerful

The real magic of a custodial Roth IRA is time. Here's how the numbers play out assuming a 10% average annual return (the S&P 500's historical average including dividends):

Scenario 1: Four Years of Maximum Contributions (Ages 15-18)

• Total contributed: $28,000 ($7,000 × 4 years)
• Value at age 65: approximately $2.1 million
• Tax savings vs. taxable account: roughly $400,000+ in avoided capital gains taxes

Scenario 2: One Year of Maximum Contribution (Age 16)

• Total contributed: $7,000
• Value at age 65: approximately $545,000
• Tax paid on that growth: $0

Scenario 3: Modest Contributions (Ages 13-17, $3,000/year)

• Total contributed: $15,000
• Value at age 65: approximately $1.4 million

Compare this to an adult who starts contributing $7,000/year at age 30 and continues for 35 years until age 65:

• Total contributed: $245,000
• Value at age 65: approximately $1.9 million

The teenager invested $28,000 and ended up with $2.1 million. The adult invested $245,000 — nearly nine times more cash — and ended up with a comparable amount. That's the power of a head start.

Withdrawal Rules: More Flexible Than You Think

One reason parents hesitate is the fear of locking money away until age 59½. But Roth IRA withdrawal rules are more permissive than most realize:

Contributions Can Be Withdrawn Anytime

Roth IRA contributions (the money you put in, not the growth) can be withdrawn at any age, for any reason, with no taxes and no penalties. If your child contributes $28,000 over four years and later needs $10,000 for a car or emergency, they can pull out $10,000 without any consequences.

First-Time Home Purchase Exception

Up to $10,000 in earnings can be withdrawn penalty-free for a first-time home purchase (the account must be at least 5 years old). For a child who opened a Roth IRA at 15, the 5-year clock is already satisfied by age 20.

Education Expenses Exception

Earnings can be withdrawn penalty-free (but not tax-free) for qualified higher education expenses. However, this is rarely the best strategy — a 529 plan is more tax-efficient for education. The Roth IRA is better preserved for its original purpose: tax-free retirement wealth.

The Real Safety Net

Because contributions come out first (before earnings) under Roth ordering rules, a custodial Roth IRA funded with $28,000 gives your child a $28,000 emergency fund they can access at any time — while the growth continues compounding tax-free for decades. This makes the "what if they need the money" concern largely moot.

Tax Filing and Record-Keeping

Does Your Child Need to File a Tax Return?

If your child's only income is from W-2 employment and they earned less than the standard deduction ($15,000 in 2026), they don't owe any federal income tax and may not need to file a return. However, if they had self-employment income exceeding $400, they'll need to file Schedule SE for self-employment taxes.

Regardless of filing requirements, it's wise to file a return anyway. A filed tax return establishes an official record of earned income, which is useful documentation if the IRS ever questions the Roth IRA contribution.

Keep These Records

• Pay stubs or payment records showing the child's earned income
• Timesheets if the child works for a family business
• 1099 forms or a simple income log for self-employment income like babysitting
• Bank statements showing deposits of earned income

You don't need to submit these with a tax return, but having them on file protects you in case of an audit.

Common Mistakes to Avoid

1. Contributing More Than Earned Income

If your child earns $4,000 this year, the maximum Roth IRA contribution is $4,000 — not $7,000. Excess contributions trigger a 6% penalty for every year the excess remains in the account.

2. Paying an Unreasonable Wage Through a Family Business

The IRS expects wages to be reasonable for the work performed. Paying a 10-year-old $25/hour for sweeping floors invites scrutiny. Document the work, pay a market rate, and make sure the tasks are age-appropriate and genuine.

3. Counting Allowance or Chore Money as Earned Income

Paying your child to do household chores doesn't create earned income. There's no employer-employee relationship for tasks that family members normally do. The income needs to come from a legitimate work arrangement — ideally with a third party, or through a formal family business employment setup.

4. Leaving the Money in Cash

A surprising number of custodial Roth IRA accounts are opened, funded, and then left sitting in a money market sweep account earning minimal returns. Always invest the contribution into an age-appropriate growth fund.

5. Not Having a Conversation About the Account

When the account converts to your child's control at 18 or 21, they can do whatever they want with it — including cashing it out. The most important "investment" is educating your child about why this money exists and the extraordinary advantage of leaving it alone. Families who involve their children in the investment process report better outcomes.

What Happens When Your Child Turns 18 (or 21)?

At the age of majority in your state — 18 in most states, 19 in Alabama and Nebraska, 21 in Mississippi — the custodial Roth IRA converts to a standard Roth IRA in your child's name. You're removed as custodian, and your child gains full control.

This is irrevocable. You cannot prevent your child from withdrawing the money. This is why financial education alongside the account is critical. But here's the practical reality: most young adults who understand what's in their Roth IRA — and what it will become — leave it alone. A 20-year-old looking at a $35,000 account that's projected to become $1.5 million tax-free has a powerful incentive to keep it growing.

Your child can also continue contributing to the same Roth IRA throughout their adult life, subject to normal income limits and contribution caps. The account seamlessly becomes their primary retirement savings vehicle.

The Bottom Line

A custodial Roth IRA is the most tax-efficient wealth transfer available to families with working children. It requires no complex trust structures, no estate planning attorneys, and no sophisticated investment strategies. Open an account at a no-fee brokerage, contribute up to your child's earned income, invest in a low-cost index fund, and let time do the rest.

The hardest part isn't the mechanics — it's starting. Every year you wait is a year of tax-free compounding your child doesn't get back. If your teenager earned money this summer, the best time to open their Roth IRA is now.
