Custodial Roth IRA for Kids: Tax-Free Retirement Wealth from Teenage Years

A custodial Roth IRA is one of the most powerful wealth-building tools available to families with teenagers. If your fourteen-year-old works a part-time job, you can open a Roth IRA in their name. They contribute a portion of their earnings, and the account grows tax-free for 50+ years. At retirement (age 65+), they withdraw tax-free. A teenager who invests $5,000/year for five years (ages 14–18) and does nothing else ends up with roughly $700,000+ in tax-free retirement wealth by age 65. The math is extraordinary. Yet most families don't take advantage of it because they don't know the option exists or don't understand the rules.

This article explains custodial Roth IRAs: how they work, why they're powerful, how to open one, what the rules are, and how to use them strategically to build massive tax-free wealth for your teenager.

Quick definition: A custodial Roth IRA is a retirement account for a minor who has earned income. The child (or parent) contributes earned income, it grows tax-free, and at retirement they withdraw tax-free. It requires real, documented earned income to work.

Key takeaways​

  • Only available if the child has earned income — they must have a real job and documented earned income to contribute
  • Contribution limit: $7,000 per year (2024) or 100% of earned income, whichever is less (meaning a kid earning $3,500 can contribute max $3,500)
  • Money grows tax-free for 50+ years — no capital gains tax, no dividend tax, no tax on withdrawal in retirement
  • Tax-free withdrawals in retirement — this is the key advantage over traditional IRAs
  • Early withdrawal rules are strict — withdrawing before retirement incurs penalties and taxes, but earned income contributions can be withdrawn penalty-free
  • Parent is custodian — you manage the account until age 18–21, then the child takes control
  • Most powerful for teenagers age 14–18 — five years of contributions compound for 50+ years to retirement
  • Works for any earned income — W-2 jobs, self-employment, modeling, influencer income, babysitting, lawn care

Why a Custodial Roth IRA is Extraordinarily Powerful​

The math is stunning. Let's compare three teenagers and their long-term wealth:

Teenager A: No Roth IRA

  • Works at age 14–18, earns $25,000 total
  • Spends all earnings
  • Invests nothing for retirement
  • At retirement (age 65): $0 in tax-free retirement wealth from these teenage years

Teenager B: Contributes $5,000/year ages 14–18 to a Roth IRA

  • Works, earns enough to contribute $5,000 × 5 years = $25,000 total contribution
  • Roth account grows at 7% per year for 47 years (age 18 to 65)
  • At retirement: approximately $724,000 in tax-free wealth

Teenager C: Waits until 25 to start retirement savings, then saves $10,000/year for 40 years

  • Contributes $400,000 total ($10,000 × 40 years)
  • Account grows at 7% per year for 40 years
  • At retirement: approximately $1,865,000

Notice: Teenager B contributed $25,000 (what they earned ages 14–18) and ended up with $724,000. Teenager C contributed $400,000 (16 times more!) and only had 2.6 times more wealth. The difference is time. Teenager B had 47 years of compound growth. Teenager C had 40 years. That seven-year advantage, starting in the teen years, is enormous.

This is the most powerful single action you can take for your teenager's retirement. Open a Roth IRA as soon as they have earned income. Encourage (or require) them to contribute a portion of earnings. Let compound growth do the rest.

Key Rules and Limitations​

A custodial Roth IRA has specific rules you must follow for it to work.

Rule 1: The Child Must Have Earned Income​

You cannot contribute to a Roth IRA without earned income. "Earned income" means:

  • W-2 income from a job (McDonald's, retail, babysitting)
  • Self-employment income (lawn care business, tutoring, modeling)
  • Income from an app or website they created
  • Acting, modeling, or influencer income (documented)

"Earned income" does not include:

  • Allowance (even if tied to chores)
  • Gifts from parents or grandparents
  • Investment earnings
  • Babysitting money if it's under-the-table (must be reported)
  • Gifts you disguise as "payment for work"

The rule is strict because the IRS wants evidence of real work. If you claim your ten-year-old worked and earned $20,000, and they actually did nothing, that's tax fraud.

Rule 2: Contribution Limits​

You can contribute up to the lesser of:

  • $7,000 per year (2024; adjusted annually for inflation), or
  • 100% of the child's earned income

Example calculations:

  • Child earns $3,000 from a summer job → can contribute max $3,000
  • Child earns $8,000 from part-time work → can contribute max $7,000 (not the full $8,000, due to the annual limit)
  • Child earns $15,000 from a year-round job → can contribute max $7,000

Rule 3: Who Controls the Contribution Source​

Here's an important rule: The child must contribute from their own earned income. You cannot contribute on their behalf using your own money.

If your child earns $5,000 and you want them to contribute $5,000 to their Roth IRA, the $5,000 must come from the child's earnings, not from your pocket.

However, there's a practical workaround: You can give the child money and have them gift it to the Roth IRA, as long as the amount doesn't exceed their earned income. For example:

  • Child earns $5,000 from a job
  • You give them $5,000 (as an allowance, gift, etc.)
  • They use their $5,000 earnings to pay for living expenses
  • They contribute the $5,000 you gave them to the Roth IRA

This is legal. The rule is about the contribution's source, not the literal dollars. As long as the child had earned income equal to the contribution, you can fund it.

Rule 4: Withdrawal Rules​

Roth IRAs have strict withdrawal rules. Understanding them prevents costly mistakes.

Contributions can be withdrawn anytime, penalty-free. If your child contributes $5,000 and later needs that money, they can withdraw the $5,000 contribution with no penalty or tax.

Earnings cannot be withdrawn before age 59½ without penalties, with limited exceptions (disability, certain educational uses, first-time home buying—limited to $10,000 lifetime). Withdrawals before 59½ incur a 10% penalty plus income tax on the earnings.

Example:

  • Child contributes $5,000 per year ages 14–18 = $25,000 total contribution
  • At 20, account grows to $30,000 ($25,000 contribution + $5,000 earnings)
  • They withdraw $10,000: They can withdraw all $10,000 as contributions; no penalty or tax
  • They withdraw $15,000: First $10,000 is contributions (no penalty); the remaining $5,000 is earnings, so they pay tax + 10% penalty on the $5,000

This rule matters less for teenagers who won't touch the account before retirement, but it's important to understand.

Exception: The 5-year rule. For tax-free withdrawals in retirement, the account must have been open for at least 5 years. If your child opens a Roth at 14, they can withdraw tax-free earnings at 19 (5 years later). Most importantly, if they open at 14 and retire at 65, they've satisfied the 5-year rule many times over.

How to Open a Custodial Roth IRA​

Step 1: Confirm Your Child Has Earned Income​

Your child must have a real job with documented income. W-2 jobs are simplest. Self-employment income (lawn care, tutoring, babysitting) must be reported on tax forms (Schedule C on their tax return).

Step 2: Choose a Brokerage​

Open the account at a major brokerage:

  • Fidelity — excellent for custodial accounts; good educational materials
  • Vanguard — strong investment options; investor-friendly
  • Charles Schwab — user-friendly; good for first-time investors
  • E*Trade — similar options to competitors

Step 3: Open the Account​

Go to the brokerage's website and choose "Open a Custodial Roth IRA" (or "Roth IRA for Minors"). You'll need:

  • Your ID
  • Your child's Social Security number
  • Your child's date of birth
  • Documentation of earned income (recent pay stubs, tax return, 1099 forms)
  • Initial funding source (check, transfer from your account)

Step 4: Fund the Account​

Contribute up to the limit based on earned income. The contribution should come from the child's earnings (or money you gift the child, which they then contribute).

Step 5: Choose Investments​

As custodian, you choose how the money is invested. For a teenager, you can:

  • Invest entirely in a target-date fund (e.g., "Vanguard Target Retirement 2060" for someone retiring around 2060). These funds automatically become more conservative as the child ages.
  • Use a diversified portfolio of index funds (70% stocks, 30% bonds; adjust as they age).
  • Let the child choose investments (if age 16+, they might understand stocks; if younger, you decide).

For teenagers, invest aggressively (80–90% stocks, 10–20% bonds). They have 50 years until retirement. They can weather market downturns. The long time horizon allows stock-market risk.

Step 6: Teach Your Child About It​

Explain the account: "This is your retirement account. You contribute money from your job. It grows tax-free. When you retire in 50 years, you withdraw it tax-free. This is how wealthy people become wealthy—they invest young and let time work for them."

Make it concrete: "You contributed $3,000 this year. Over 50 years at 7% growth, that $3,000 becomes $100,000. And you do this every year you work. By 65, you'll have massive retirement savings without paying taxes."

Step 7: Repeat Every Year​

Every year your child works, contribute to the Roth. Make it a ritual: "You got your paycheck, great! Let's contribute $500–5,000 to your retirement account."

If they're earning a lot (say, $10,000/year) and you want to maximize, you could contribute the full $7,000 limit.

Strategic Uses and Scenarios​

Scenario 1: Part-Time Job Teenager​

Your fourteen-year-old works at a grocery store earning $200/week ($10,400/year). You encourage them to save and contribute $5,000 to a Roth IRA. They fund it from their earnings (or you gift them the $5,000 and they direct their paycheck to living expenses). By age 18, they've contributed $20,000. The account grows to ~$28,000 by age 18. By age 65, that grows to roughly $500,000–600,000 depending on market performance.

Scenario 2: High-Earning Teen​

Your sixteen-year-old is a YouTuber with documented income of $30,000/year. You open a Roth IRA and contribute the full $7,000/year. By age 18, they've contributed $14,000. The account grows to ~$20,000 by age 18. By retirement, that becomes $350,000–400,000.

Scenario 3: Multiple Working Kids​

You have three teenagers, all with jobs. You open Roth IRAs for each. Over time, you contribute for all three. At retirement, you've set up each child with hundreds of thousands in tax-free retirement wealth, starting from their teenage years. This is one of the most powerful wealth transfers you can make.

Scenario 4: Family Business​

Your child works in your family business and earns a documented salary. You open a Roth IRA and contribute up to their salary. They own the business, build personal wealth, and save for retirement—simultaneously. By the time they fully take over the business at 30, they have $100,000+ in their personal Roth from their teenage years alone.

Diagrams and Decision Tree​

Common Mistakes Parents Make​

Mistake 1: Waiting too long to open a Roth IRA. Your child works starting at sixteen. You wait until they're twenty to open a Roth. By then, they've lost four years of compound growth. Opening at fourteen (when they first earn) captures those early, high-growth years. Open immediately when they start earning.

Mistake 2: Contributing your money instead of theirs. You want to maximize contributions, so you put $7,000 of your own money in the account. The IRS flags this—the contribution must come from the child's earned income or money you gift the child (which they then contribute). Avoid this by having the child's earnings feed the contribution.

Mistake 3: Not documenting the earned income. Your child babysits and you want to contribute $5,000 to a Roth. But there's no documentation: no tax return, no W-2, nothing. If audited, the IRS won't allow the contribution. Ensure earned income is documented: W-2 jobs are automatic; self-employment income should be reported on Schedule C (even if they don't owe taxes, they should file).

Mistake 4: Investing too conservatively. Your child has 50 years until retirement. You invest their Roth IRA in bonds earning 2%/year. The account barely grows. At retirement, they have far less than they could have. Invest aggressively (80%+ stocks) for long-term accounts.

Mistake 5: Using the Roth for short-term needs. Your child needs money for a car down payment at age twenty. They withdraw from the Roth IRA. They pay tax and penalty on the earnings portion and lose decades of growth. Roth IRAs should be sacred—not touched until retirement. If they need money, they should get a personal loan or save separately.

Mistake 6: Forgetting to file taxes. Your child earns $3,000 from self-employment babysitting and contributes to a Roth. If they don't file a tax return that year, the IRS might disallow the contribution. Even if the child has no tax liability, they should file to document the income. Have them file annually (or ensure a W-2 is issued if they're an employee).

FAQ​

What if my child doesn't earn money?​

They can't have a Roth IRA. A Roth IRA requires earned income. If your child doesn't work, focus on other vehicles: custodial taxable accounts (UTMA/UGMA), 529 plans for education, or a savings account. Once they start working (babysitting, lawn care, part-time job), then open a Roth.

Can I contribute to my child's Roth IRA if they don't want to?​

Technically yes, but ethically no. A Roth IRA is the child's account. They should understand what it is and agree to contribute. If you force contributions against their will, you're removing money from their control (they can't access it before age 59½ without penalty). Explain the benefit and let them choose.

What if my child earns $3,000 but I want to contribute $7,000?​

You can't. The contribution limit is 100% of earned income. If they earned $3,000, the max contribution is $3,000. You could gift them additional money (so they have $10,000), but only $3,000 can go into the Roth IRA (limited by earned income).

However, here's the workaround: If the child will work again next year and earn $7,000, you can max out the current year and then catch up next year. Or, if they've earned $15,000 total over multiple years and haven't contributed yet, they can contribute up to $7,000 in a single year (not exceeding the annual limit).

Does the child control the Roth at 18?​

Not completely. You're the custodian. You manage the account, make investment decisions, and handle transactions. At age 18–21 (varies by state), the account transfers to the child. From that point, they have full control—though ideally, you've taught them not to withdraw it until retirement.

Can my child have both a Roth IRA and a 401(k)?​

If they work for an employer that offers a 401(k) (unlikely for teenagers), they could have both. But most teenagers only have Roth IRAs. Once they're older and employed by a company with a 401(k), they can contribute to both (up to annual limits combined across accounts).

What happens if they stop working?​

If your child's job ends, they can stop contributing. The money in the Roth keeps growing tax-free. When they get another job, they can contribute again. The account is persistent—it doesn't close or penalize if they take a year off from working.

Can I deduct contributions from my taxes?​

No. Roth IRA contributions are made with after-tax money. You don't get a tax deduction. (This is why Roth is valuable—no deduction, but tax-free growth and withdrawals, which is a great trade-off over 50 years.)

However, there's a Dependent Care FSA or Flexible Spending Account (HSA if the child is on a high-deductible health plan) that could provide tax savings. But that's a separate account, not the Roth.

What if my child wants to withdraw at 25?​

They can withdraw contributions (the money they personally contributed) with no penalty. They cannot withdraw earnings without a 10% penalty and taxes (with limited exceptions like disability or first-time home buying). This is by design—the account is meant for retirement, and the government penalizes early access to earnings.

Real-world examples​

Example 1: The early-start teenager. Marcus is fourteen when he starts working at a grocery store, earning $200/week ($10,400/year). His parents open a Roth IRA and contribute $5,000 of his earnings in year one. They do the same each year for four more years (through age 18). Total contribution: $25,000. He doesn't contribute anymore after 18 (he goes to college, needs money). The $25,000 sits in the account, growing at 7%/year for 47 years (to age 65). By retirement, it's approximately $724,000 in tax-free wealth. He never contributed another dollar after 18, but those five early years set him up for life.

Example 2: The influencer teen. Sofia is sixteen and makes $30,000/year as a TikTok creator (well-documented income, reported on taxes). Her parents max out her Roth IRA contribution at $7,000/year for ages 16–20 (she stops at 20 to focus on college). Total contribution: $35,000. By age 65, that grows to approximately $800,000+ tax-free. She's built massive retirement wealth before most people even graduate college.

Example 3: The self-employment teen. James is fifteen and starts a lawn care business, earning $400/month ($4,800/year). His parents help him open a Roth and contribute $4,000/year from his business income (he keeps the rest for personal spending). Over five years, he contributes $20,000. By retirement, it's approximately $500,000 tax-free. The business taught him entrepreneurship; the Roth taught him wealth-building.

Example 4: The missed opportunity. Sarah's parents could have opened a Roth when she was fourteen and working, but they didn't. She didn't learn about Roth IRAs until age 25, when she was out of college and earning $45,000/year. She opened a Roth and started contributing $7,000/year. By 65, she has about $1.2 million (40 years of contributions and growth). Compare this to Marcus (above), who started at fourteen with just $25,000 contributed and ended up with $724,000. Sarah contributed 40 times more and only has 1.7 times more wealth. The eleven-year head start (Marcus at 14 vs. Sarah at 25) makes an enormous difference.

Summary​

A custodial Roth IRA is the single most powerful wealth-building tool available to families with working teenagers. It requires earned income (a real job), has a $7,000/year contribution limit (or 100% of earned income, whichever is less), and grows tax-free. A teenager who contributes $5,000/year from ages 14–18 ($25,000 total) will have $700,000+ by retirement without contributing another dollar. This is the power of time and compound growth. Most families don't take advantage of this because they don't know it exists or understand the rules. Opening a Roth IRA the moment your child starts working is one of the highest-return actions you can take for their long-term financial security. Combined with teaching them about work, saving, and investing, a custodial Roth IRA sets them on a trajectory toward financial independence and generational wealth.
