When And Why Your Child Should Open A Roth IRA

Imagine if you could hand your child a million-dollar gift — without winning the lottery, without inheritance, and without needing a high-paying job yourself.

Sounds impossible, right? But with just a few summers of babysitting, mowing lawns, or scooping ice cream, your child could set themselves up for millions in tax-free retirement savings.

That’s the magic of opening a custodial Roth IRA early in life.

Parents in the financial independence (FI) community already know the power of compounding returns. But most don’t realize you can harness that same force for your kids — and the earlier they start, the more exponential the results.

The Power of Compounding

If you’re on the FI path, you already know the magic of compounding. But let’s put some numbers on it:

$10,000 at 10% grows to $27,000 in 10 years
Leave it for 20 years, it’s $70,000
Leave it for 50 years, it’s nearly $1.5 million

👉 The lesson: The earlier you invest, the more exponential the results.

Now imagine giving your child the ability to let their money grow tax-free for 50+ years. That’s where the Roth IRA comes in.

Would you like me to take this even further and add a short parent-focused hook like: "The best financial gift isn’t a college fund or a car — it’s teaching your child to invest early" … right before diving into compounding? That could make the opening even sharper.

2025 Roth IRA Contribution Limits

For 2025, your child can contribute:

Up to $7,000 (the IRS Roth IRA limit), or
Their earned income for the year, whichever is lower.

(Once they hit age 50, there’s an extra $1,000 “catch-up” — but let’s focus on starting early!)

When Can a Child Open a Roth IRA?

Kids can’t open their own accounts, but parents can open a custodial Roth IRA on their behalf.

Rules to know:

The child must have earned income.
Earned income = wages (W-2 job), or self-employment income (babysitting, tutoring, lawn care, etc.) reported to the IRS.
Allowances or gifts don’t count.

👉 Parents who own businesses can employ their children, provided labor laws are followed. Bonus: if the business is 100% parent-owned, kids don’t owe FUTA (federal unemployment) taxes (IRS source).

Why a Roth IRA for Kids Is So Powerful

Let’s compare two kids who each invest $7,000/year for 20 years at 10% returns:

Kid A (starts at 15, invests until 35, then stops): Nearly $7 million by 65.
Kid B (starts at 25, invests until 45, then stops): Just $2.5 million by 65.

👉 Same contribution amount. One decade earlier = $4.5 million more wealth.

That’s the magic of combining time + compounding.

Additional Benefits

Low/zero tax cost: Most kids earn so little they pay no federal tax on contributions. Growth = tax-free forever.
Withdraw contributions anytime: Contributions (not earnings) can be withdrawn tax- and penalty-free.
Special exceptions: After 5 years, up to $10,000 can be used penalty-free for a first home, or funds can be tapped for disability, unreimbursed medical expenses, or health insurance during unemployment.

Documentation & Record-Keeping Tips for Parents

Since the IRS requires contributions to be backed by earned income, documentation matters. Here’s how parents can help:

Track income: Kids can keep a simple spreadsheet logging babysitting, lawn care, or tutoring jobs. Include date, client, hours, and pay.
Deposit earnings: Encourage kids to deposit cash into a bank account for a clear paper trail. Apps like Venmo or PayPal also create records.
Keep receipts or invoices: Even handwritten receipts signed by clients help.
File taxes: Even if no tax is owed, filing a return officially documents the income. (Required if net self-employment income > $400.)

Case Study: Ella’s Babysitting Roth IRA

Meet Ella, age 14. She babysits for neighbors a few evenings each week and makes about $1,200 per year.

Her parents want to help her start a Roth IRA, but they also know the IRS requires that contributions come from real earned income. Here’s how they make it work:

Step 1: Track the Income

Ella creates a simple Google Sheet where she logs each babysitting job: date, family, hours, and pay.
Families often pay by Venmo, which creates a digital record. When they pay in cash, Ella writes a receipt and deposits it into her checking account.

Step 2: File Taxes (Even If Not Required)

Because Ella’s income is under the standard deduction (over $14,000 in 2025), she doesn’t owe any federal tax.
Still, her parents help her file a simple tax return to officially document her earned income with the IRS.

Step 3: Open a Custodial Roth IRA

Ella’s parents open a custodial Roth IRA in her name.
They contribute the full $1,200 she earned, even though technically the parents provide the money (since contributions can come from anyone — as long as the child had earned income).

Step 4: Let Compounding Do Its Work

Ella invests the $1,200 in a broad-market index fund.
If she keeps contributing $1,200 each year from age 14 to 18, she’ll have invested $6,000 total.

Now let’s let compounding take over:

At age 65, assuming a 10% annual return, that $6,000 contribution grows into over $500,000 — tax-free.
And that’s without a single contribution after high school!

👉 The Takeaway: By babysitting just a few nights a month and keeping good records, Ella has essentially set herself up with half a million dollars in retirement — tax-free.

Now imagine if she keeps contributing through her 20s or beyond. The numbers quickly become life-changing.

Things to Watch Out For

Income must be legitimate and reported. Don’t fudge numbers.
Self-employment taxes: Even kids must pay them if net earnings exceed $400.
College financial aid: Assets in the child’s name can impact aid eligibility.
Custodial accounts transfer: At 18–21 (depending on state), kids gain full control of the Roth.

FAQs: Roth IRAs for Kids

❓ Can my child still qualify me for the Child Tax Credit if they earn money and have a Roth IRA?✅ Yes. As long as they’re under 17, live at home, and you provide more than half their support, you can still claim them — even if they file taxes and contribute to a Roth IRA.

IRS Dependency Rules

To claim a child as a dependent, the IRS looks at a few tests (Pub. 501):

Age Test – The child must be under 19 (or under 24 if a full-time student).
Residency Test – The child must live with you for more than half the year.
Support Test – The child cannot provide more than half of their own support.
Relationship Test – Must be your son, daughter, stepchild, foster child, etc.

👉 Ella in our example clearly qualifies: she’s under 19, lives at home, and her babysitting income isn’t anywhere near enough to cover half of her support.

How Earned Income Affects the Child Tax Credit

The Child Tax Credit doesn’t phase out just because your child earns income.
As long as she’s under age 17 at year-end and meets the dependency tests, parents can still claim the up to $2,000 per child CTC.
Ella may need to file a tax return to report her babysitting income (especially if self-employed and over $400 net income), but that doesn’t stop parents from claiming her.

Key Distinction:

Her earned income only matters for the Roth IRA contribution rules, not for your ability to claim her as a dependent.

✅ Bottom line: Yes, parents can still claim the Child Tax Credit even if their child earns money, files a tax return, and contributes to a Roth IRA — as long as the dependency rules are met.

❓ Can my child contribute if they only earn $500?Yes. Contributions are capped at the lesser of their earned income or $7,000 (2025 limit). So $500 earned = max $500 contributed.

❓ Can parents or grandparents fund the Roth IRA?Yes — as long as the contribution doesn’t exceed the child’s earned income for the year.

❓ What counts as earned income?W-2 wages, 1099 income, or self-employment (babysitting, lawn mowing, etc.). Allowances and gifts don’t count.

❓ What happens when my child turns 18 (or 21)?The custodial Roth automatically transfers to them as a standard Roth IRA.

❓ What if my child withdraws money early?Contributions can always be withdrawn penalty-free. Earnings must generally stay in until 59½ unless an exception applies.

Final Thoughts

Opening a custodial Roth IRA may be the single best financial gift you can give your kids. With decades of compounding, tax-free growth, and the lessons of earning, saving, and investing early, it’s a foundation for lifelong financial independence.

Even small contributions — babysitting money, summer jobs, or side hustles — can snowball into millions over a lifetime.

All it takes: legitimate income, simple record-keeping, and the discipline to let compounding work its magic.
