Custodial Roth IRA for Kids: 2026 Rules, Limits, and the Case for Starting Early

A Roth IRA isn't just for adults. If your child has earned income — from a summer job, babysitting, lawn care, or acting — they qualify for a Roth IRA. You open and control the account as custodian, invest the money, and hand control over when they reach adulthood. The money compounds tax-free for 50+ years.

The math is hard to ignore: $7,500 invested at age 15 grows to roughly $206,000 by age 65 at a 7% average annual return — completely tax-free. That's one year's contribution becoming six figures with zero additional deposits. Starting early is the whole strategy.

What is a custodial Roth IRA?

A custodial Roth IRA is a standard Roth IRA held in a minor's name, with a parent or guardian named as custodian. The custodian controls all account decisions — what to invest in, whether to contribute each year — until the child reaches the age of majority (18–21, depending on state). At that point, the account transfers automatically to the child's sole control.

Structurally it works identically to an adult Roth IRA:

• Contributions are made with after-tax dollars
• Growth is completely tax-free inside the account
• Qualified withdrawals in retirement (age 59½+, account open 5+ years) are tax-free
• Contributions (not earnings) can be withdrawn anytime without tax or penalty

The earned income requirement — and what qualifies

The IRS requires that IRA contributions not exceed the account holder's earned income for the year. For a custodial Roth IRA, that means your child must have income that would appear on a W-2, 1099-NEC, or Schedule C. Common sources:

Key practical point: the money deposited into the Roth IRA doesn't have to be the child's paycheck. If your 16-year-old earns $4,000 lifeguarding and wants to keep their earnings, you can deposit $4,000 of your own money into their Roth IRA — as long as the contribution doesn't exceed their total earned income for the year. The IRS doesn't require the dollars to be the same dollars; it just requires the child to have earned at least that amount.

Custodial Roth IRA vs. 529 vs. UTMA

These three accounts serve different purposes. Many families use all three — but understanding where each fits helps you allocate correctly.

FAFSA advantage: Roth IRA is completely invisible

Under the current FAFSA formula, retirement account balances — including Roth IRAs — are entirely excluded from the Student Aid Index calculation. A $50,000 custodial Roth IRA balance has zero impact on financial aid eligibility.

Compare this to a UTMA account, where student-owned assets count at 20% in the SAI. A $50,000 UTMA account increases the family's expected contribution by $10,000 per year — potentially eliminating $10,000 of need-based aid annually across four years of college.

For families who may qualify for merit or need-based aid, building wealth in a custodial Roth IRA instead of a UTMA preserves financial aid eligibility while still building tax-advantaged assets for the child.

The 5-year rule and early withdrawal

Roth IRA accounts have a 5-year holding period that starts from January 1 of the first year a contribution is made. For a custodial Roth IRA opened when the child is 14, the 5-year clock starts immediately and is satisfied well before the child could access earnings.

Two things to know:

• Contributions can always be withdrawn first, tax-free and penalty-free, at any age. If your child contributes $5,000 and the account grows to $8,000, they can withdraw up to $5,000 anytime without tax or penalty. Earnings stay in the account to preserve tax-free growth.
• Earnings are locked until 59½ for penalty-free withdrawal (with exceptions for disability, first home, and higher education expenses). Building a habit of leaving earnings invested is the right approach — they're what make the account extraordinary over 40+ years.

How to open a custodial Roth IRA: step by step

1. Confirm your child has earned income. Check W-2, 1099-NEC, or documented self-employment records for the year. You cannot open the account or make contributions before the child has earned income.
2. Choose a custodian. Fidelity ("Roth IRA for Kids"), Schwab ("Custodial Roth IRA"), and Vanguard all offer no-fee custodial Roth IRAs with no minimum balance. Fidelity is often the easiest for online setup.
3. Open the account online. The parent or guardian signs as custodian. You'll need your child's Social Security number, your SSN, and basic household information.
4. Fund the account. Contribute up to the lesser of the child's earned income or $7,500 for 2026. You can contribute your own money — the limit is based on the child's earnings, not whose dollars you use.
5. Invest the money. Don't leave it in cash. A low-cost total market index fund (like FXAIX, SCHB, or VTSAX) is appropriate for a child's 50-year time horizon. The custodian makes all investment decisions until the account transfers to the child.
6. Document the child's earnings. Keep copies of W-2s, 1099s, or payment records. The IRS can question IRA contributions without documentation of earned income.

What happens when your child turns 18 (or 21)?

At the age of majority in your state — typically 18, or 21 in some states — the custodial Roth IRA converts to a standard Roth IRA in your child's name. The custodian loses control. The brokerage sends account transfer paperwork to your child.

This is why having a conversation about the account early matters. A teenager who grows up knowing "there's a Roth IRA in your name, here's what it is, here's why we leave it alone" is far less likely to cash it out at 22 than one who discovers the account unexpectedly. The educational component is part of the value.

Priority order: where does the custodial Roth fit?

For most families, this is the right sequence:

1. Max employer 401(k) match for both parents (free money first)
2. HSA family limit if you have an HDHP ($8,750 in 2026)
3. Roth IRA for each parent (up to $7,500/person in 2026)
4. 529 for college savings targets
5. Custodial Roth IRA for working-age children — as much as their earned income allows, up to $7,500
6. Additional 401(k) contributions to max

The custodial Roth IRA comes after parents' own retirement security — not because it's less valuable per dollar (the opposite is true — time horizon is longer), but because parents can't fund their own retirement on loans. Once the core retirement stack is funded, opening a custodial Roth for a working child is one of the highest-leverage moves available.
