Custodial Accounts (UGMA/UTMA): Investing for Your Child's Future

UGMA vs UTMA: What's the Difference?

UGMA accounts can hold cash, stocks, bonds, mutual funds, insurance policies, and annuities. They are simpler and available in all 50 states. UTMA accounts can hold everything UGMA can, plus additional asset types including real estate, art, patents, and royalties. UTMA is more flexible but not available in all states -- South Carolina and Vermont only offer UGMA accounts. For most families investing in stocks, bonds, and ETFs, UGMA is sufficient. UTMA becomes relevant if you plan to transfer physical assets like real estate or intellectual property to a minor. In both cases, the custodian manages the assets until the child reaches the age of majority. Understand the tax implications →

Tax Treatment of Custodial Accounts

Custodial account income is taxed under "kiddie tax" rules. For 2024: unearned income up to $1,250 is tax-free (covered by the child's standard deduction). The next $1,250 is taxed at the child's tax rate (typically 10% for most children). Unearned income above $2,500 is taxed at the parent's marginal tax rate. These rules apply until the child turns 19 (or 24 if a full-time student). Once the child is past these ages, all income is taxed at the child's rate. This means custodial accounts have limited tax advantages compared to 529 plans or Roth IRAs. The first $1,250 of gains is free, but beyond that, tax efficiency drops quickly.

Financial Aid Impact

Custodial accounts are treated as student assets on the FAFSA, assessed at a rate of 20%. This means if a custodial account has $100,000, the expected family contribution from that account is $20,000 per year. By comparison, parent-owned assets (including 529 plans) are assessed at a maximum rate of 5.64%. Parent-owned accounts in the parent's name are also sheltered by an asset protection allowance. This makes custodial accounts significantly less favorable than 529 plans for families expecting to qualify for need-based financial aid. If financial aid is a concern, consider funding a 529 plan instead of a custodial account, or limit custodial account contributions. Learn more about 529 plans →

What happens to a custodial account when the child turns 18?

At the age of majority (18 in most states, 21 in some), the custodian's control ends and the account legally belongs to the child. The child gains full access to all assets with absolutely no restrictions. They can spend the money on college, a car, a business, travel, or anything else -- including things you might not approve of. There is no legal mechanism to restrict how the child uses the money once they reach the age of majority. This is the biggest risk of custodial accounts. If you want more control, consider a trust with specific distribution terms (e.g., funds released at age 25 or for specific purposes like education or a home purchase).

Are custodial accounts better than 529 plans?

Custodial accounts offer more flexibility because the money can be used for any purpose, not just education. However, 529 plans have significant advantages: tax-free growth and withdrawals for qualified education expenses, parent-controlled (child cannot access the funds), and more favorable financial aid treatment (assessed at 5.64% vs 20%). If you are saving for education specifically, a 529 plan is almost always better. If you want to give the child money for any purpose (first car, wedding, down payment, business startup), a custodial account provides that flexibility. Many families fund both: a 529 plan for education and a smaller custodial account for other expenses.

How are custodial accounts taxed?

Custodial accounts are subject to the kiddie tax. In 2024, the first $1,250 of unearned income is tax-free (child's standard deduction). The next $1,250 is taxed at the child's rate (usually 10%). Any unearned income above $2,500 is taxed at the parent's marginal rate. This applies until the child turns 19 (or 24 if a full-time student). After that age, all income is taxed at the child's rate. This structure means custodial accounts offer limited tax sheltering. For significant savings, consider strategies that shift income to the child's bracket more efficiently, or use tax-advantaged accounts like 529 plans or Roth IRAs.

Can I use custodial account money for anything other than education?

Yes, custodial account money can be used for any purpose that benefits the child. There are no restrictions on how the funds are spent. Common uses include college tuition, a first car, a down payment on a home, starting a business, medical expenses, or travel. Unlike a 529 plan, there are no penalties for non-education withdrawals. However, the custodian must act in the child's best interest -- using custodial funds for your own expenses (like a family vacation or home renovation) would be considered a breach of fiduciary duty and could have legal consequences. Once the child reaches the age of majority, they can use the money for any purpose without restriction. Explore estate planning basics →
