IRA for Kids: Custodial Accounts for Minors Explained (2026 Guide)

I’ll never forget the look on my neighbor’s face when I told him his 12-year-old daughter could have a retirement account. “She’s in middle school,” he said. “She doesn’t even know what a 401(k) is.” But here’s the thing: by the time she’s my age—mid-40s—that $1,000 she earned babysitting last summer, invested in a Roth IRA, could be worth over $30,000 tax-free. Meanwhile, if I had waited until age 30 to invest the same amount, it would barely crack $7,000. That’s not magic. That’s compound growth with a 50-year head start. In this 2026 guide, I’ll walk you through exactly how to open and manage an IRA for kids—custodial accounts for minors explained from the ground up, with real-world steps, tax rules, and strategies that actually work.

Why Open an IRA for a Minor? The Real-World Benefits (Beyond the Tax Break)

Most parents think about college savings—529 plans, UGMAs, maybe a high-yield savings account. But a custodial IRA? That feels like overkill. Until you run the numbers. Let’s take a concrete example: Your 10-year-old earns $1,000 from a summer lawn-mowing gig. You open a Roth IRA for them and invest that $1,000 in a low-cost total stock market index fund averaging 8% annual returns. By age 65, that single contribution grows to about $46,000—tax-free. Compare that to the same $1,000 invested at age 30: it grows to roughly $7,000. The difference? 20 years of compounding. That’s not a tax break—it’s a wealth multiplier.

Beyond the math, there’s a behavioral benefit: kids who see their money growing in an IRA learn investing habits early. My own nephew, now 16, checks his custodial Roth balance every month. He’s stopped asking for video games and started asking about dividend yields. That’s the kind of financial literacy no school teaches.

And yes, the tax break matters. With a Roth IRA, contributions are made with after-tax dollars (at your child’s low or zero tax bracket), and all withdrawals in retirement are completely tax-free. For a kid earning $2,000 a year, that’s a permanent tax-free growth vehicle. No RMDs, no future tax bill. It’s hard to beat.

Eligibility Requirements: What Counts as 'Earned Income' for a Child?

This is the most common tripwire. You cannot just transfer birthday money or allowance into an IRA for your child. The IRS requires that the child have earned income—money received for actual work performed. That means wages from a job, self-employment income (babysitting, lawn mowing, dog walking, selling crafts online), or even pay from a family business—as long as it’s at a fair market rate and the work is legitimate.

Here’s a quick checklist of acceptable earned income sources for a minor:

• W-2 wages from a part-time job (e.g., grocery store, restaurant, summer camp)
• Self-employment income from chores like babysitting, lawn care, or tutoring (keep records of who paid what and when)
• Pay from a family-owned business for actual work (must be reasonable compensation, not a gift)
• Freelance work like graphic design, social media management, or YouTube content creation

What does not qualify: allowance (unless tied to specific chores at market rates—and even then, it’s risky), gifts, interest from savings, or investment income. The IRS is strict here. If you contribute more than the child’s earned income, you face a 6% penalty on the excess each year until corrected. I once helped a friend who had contributed $3,000 to his son’s IRA, but the son only earned $1,500 from his paper route. That $1,500 difference triggered a penalty—and we had to withdraw the excess plus earnings to fix it. Don’t let that happen to you.

Step-by-Step: How to Set Up a Custodial IRA for Your Child

Setting up a custodial IRA is surprisingly straightforward, but the paperwork matters. Here’s the exact process I followed when I opened one for my niece last year:

1. Choose a brokerage. I recommend Fidelity, Vanguard, or Schwab—they all offer custodial Roth IRAs with no minimums and low fees. I went with Fidelity because their app is intuitive and they have a dedicated custodial account page.
2. Gather documents. You’ll need your child’s Social Security number, birth date, and your own ID as custodian. The child is the owner; you’re the manager until they reach the age of majority (usually 18 or 21, depending on your state).
3. Complete the application online. The brokerage will ask for the account type—select “Custodial Roth IRA” (or Traditional if you prefer, but Roth is almost always better for kids). You’ll list yourself as custodian and your child as the beneficiary.
4. Link a bank account. You need a funding source. Use your own bank account to transfer the contribution. The brokerage will verify it via micro-deposits.
5. Fund the account. Transfer the amount equal to your child’s earned income (up to $7,000 in 2026). Remember: you can contribute from your own funds, but the total cannot exceed what the child earned that year.
6. Invest the money. Don’t just leave it in cash. Choose an investment—I’ll cover this in the next section.

One thing I learned the hard way: double-check the contribution deadline. For 2026, the deadline is April 15, 2027, same as your own IRA. And if your child earns income mid-year, you can contribute immediately—you don’t have to wait until year-end.

Contribution Limits, Tax Rules, and Penalties You Must Know

The 2026 contribution limit for an IRA is $7,000—but for a child, it’s the lesser of $7,000 or their total earned income. So if your 14-year-old earns $2,500 from a part-time job, you can contribute up to $2,500. Not a penny more.

Tax-wise, here’s the key distinction:

• Roth IRA: Contributions are after-tax (no deduction). Withdrawals in retirement are tax-free. For a child with little to no tax liability, this is a no-brainer. No current benefit, but massive future value.
• Traditional IRA: Contributions are pre-tax (you get a deduction on your child’s tax return, if they file). But withdrawals in retirement are taxed as ordinary income. For a child earning under the standard deduction ($14,600 in 2026), the deduction is useless—they pay zero tax anyway. Plus, they lose the tax-free growth of a Roth. Stick with Roth.

Penalties to watch: If you contribute more than earned income, the excess is subject to a 6% penalty each year until removed. Also, if your child withdraws earnings (not contributions) before age 59½, they pay income tax plus a 10% penalty—unless it’s for a qualified exception (like a first-time home purchase or education). But honestly, kids should never touch this money until retirement.

Tax reporting: You don’t file a separate return for the IRA itself. But if the child’s total income (including from the IRA’s investments) exceeds $1,150 in unearned income or $14,600 in earned income, you may need to file a tax return for them. The brokerage will issue Form 5498 each year showing contributions—keep it for your records.

Investment Options for a Child's IRA: Growth-Focused Strategies

Here’s where many parents go wrong: they play it too safe. I’ve seen custodial IRAs stuffed with CDs or money market funds. That’s a mistake. A child has 50+ years until retirement—their time horizon is the ultimate advantage. They can stomach volatility and reap the rewards of equity growth.

My recommendation for a child’s Roth IRA is a simple, low-cost portfolio:

• Total stock market index fund (like VTSAX or FSKAX): 80-100% allocation. This gives exposure to thousands of U.S. companies. Over long periods, it’s hard to beat.
• Target-date fund (e.g., Vanguard 2070 fund): If you want a set-it-and-forget-it option, pick a target-date fund with a far-off date. It automatically adjusts from stocks to bonds as retirement nears—but for a kid, it’ll be nearly all stocks for decades.
• A single S&P 500 ETF (like VOO): Even simpler. One ETF, total market tracking, low expense ratio.

I personally opted for a three-fund portfolio for my niece: 80% total U.S. stock market, 15% total international stock, and 5% bonds (just for a tiny buffer). But honestly, for a kid, you could go 100% equities and sleep fine. The key is to avoid fees—stick with index funds, not actively managed funds with high expense ratios.

One caution: don’t get cute with individual stocks. I know a dad who bought Tesla shares for his son’s IRA—it worked out, but it’s gambling. For a retirement account, diversification is your friend. Let the market do the work.

Practical takeaway: Opening a custodial IRA for your child is one of the smartest financial moves you can make. It teaches them investing, locks in decades of tax-free growth, and costs nothing to set up. Start with a Roth, invest in low-cost index funds, and contribute only up to your child’s earned income. The hardest part? Remembering to do it every year. But trust me—your future 65-year-old child will thank you.
