Custodial IRAs for Minors: The Ultimate Parent's Guide to Building Your Child's Financial Future

The greatest inheritance you can leave your child isn't money—it's the compound growth from starting early. A custodial IRA transforms teenage earnings into retirement wealth that could reach seven figures.

Starting retirement savings for your child might seem premature when they're more concerned with video games than investment gains. However, a custodial IRA for minors represents one of the most powerful wealth-building tools available to families. By leveraging the extraordinary power of compound growth over decades, even modest contributions during childhood can create substantial retirement wealth.

This comprehensive guide reveals everything parents need to know about custodial IRAs, from eligibility requirements and setup procedures to advanced strategies that maximize your child's financial future.

What Is a Custodial IRA and How Does It Work?

A custodial IRA is a retirement account opened for a minor child who has earned income. While the child legally owns the account from day one, a parent or guardian serves as the custodian, managing all investment decisions and account administration until the child reaches the age of majority (typically 18 or 21, depending on state law).

Key Characteristics of Custodial IRAs

Legal Structure:

• The minor is the beneficial owner
• The custodian has fiduciary responsibility for account management
• Account transitions to child's control at age of majority
• Subject to the same IRS rules as adult IRAs

Types Available:

• Custodial Roth IRA: After-tax contributions, tax-free growth and withdrawals
• Custodial Traditional IRA: Potentially deductible contributions, tax-deferred growth

Fundamental Requirements:

• Child must have earned income from legitimate work
• Contributions cannot exceed child's annual earned income
• All standard IRA rules and restrictions apply

The custodial structure provides parents with control during the child's minor years while establishing a foundation for long-term wealth building that will benefit the child throughout their lifetime.

The Mathematical Magic: Why Starting Early Matters

The power of custodial IRAs lies in the extraordinary impact of compound growth over extended time periods. When children start investing in their teens, they gain a 40-50 year head start compared to adults who begin retirement savings in their twenties.

The 40-Year Advantage

Starting a custodial IRA at age 14 instead of age 25 provides:

• 40 additional years of compound growth
• Exponential returns on early contributions
• Lower contribution pressure in adulthood
• Financial discipline established early

This mathematical advantage makes custodial IRAs one of the most powerful wealth-building tools available to families.

Custodial Roth vs Traditional IRA: The Clear Winner for Most Kids

For the vast majority of minors, a custodial Roth IRA is the superior choice. This preference stems from the unique tax situation most children find themselves in and the long-term benefits of tax-free growth.

Why Roth IRAs Dominate for Minors

Tax Bracket Arbitrage:

• Most minors earn small amounts, placing them in the 0% or 10% tax bracket
• Standard deduction ($14,600 in 2025) often eliminates federal tax liability entirely
• Traditional IRA deductions provide minimal or no benefit
• Roth contributions use "cheap" after-tax dollars

Decades of Tax-Free Growth:

• All growth in a Roth IRA is permanently tax-free
• No required minimum distributions during the child's lifetime
• Tax-free inheritance potential for future generations
• Protection against higher future tax rates

Traditional IRA Considerations

A traditional IRA might make sense in rare circumstances:

• High-earning minor performers (actors, athletes, models)
• Significant self-employment income creating meaningful tax liability
• State tax considerations in high-tax jurisdictions

Earned Income Requirements: What Counts and What Doesn't

The IRS requires minors to have earned income before contributing to any IRA. Understanding what qualifies as earned income is crucial for custodial IRA eligibility.

Qualified Earned Income Sources

Traditional Employment:

• W-2 wages from part-time jobs
• Restaurant work, retail positions, summer jobs
• Internships with pay (unpaid internships don't count)
• Work-study programs through schools

Self-Employment Income:

• Babysitting services
• Lawn care and landscaping
• Pet sitting and dog walking
• Tutoring services
• Technology services (website design, social media management)
• Creative work (art commissions, photography)
• Online business income (Etsy shops, YouTube revenue)

Performance Income:

• Acting, modeling, or entertainment work
• Music performances with compensation
• Athletic endorsements or prize money
• Writing income from publications

Non-Qualified Income Sources

Investment Income:

• Interest from savings accounts
• Dividend payments
• Capital gains from investments
• Rental income (generally)

Gift and Transfer Income:

• Allowances from parents
• Gift money from relatives
• Inheritance distributions
• Trust fund distributions
