UGMA and UTMA custodial accounts are one of the most flexible ways to invest for a child — but they come with unique tax rules and financial aid implications. Here’s everything you need to know.

UGMA vs. UTMA: Key Differences
| Feature | UGMA | UTMA |
|---|---|---|
| Stands for | Uniform Gifts to Minors Act | Uniform Transfers to Minors Act |
| Asset types | Cash, stocks, bonds, mutual funds, CDs | All UGMA assets + real estate, patents, art |
| Availability | All 50 states | All states except SC and VT |
| Age of termination | 18 in most states | 18 or 21 (varies by state) |
| Irrevocable? | Yes — gift cannot be taken back | Yes |
| Contribution limit | No limit (gift tax applies over $18,000/year) | No limit |
How Custodial Accounts Work
| Step | Details |
|---|---|
| Open | Adult (custodian) opens account at a brokerage in child’s name |
| Fund | Anyone can contribute — parents, grandparents, friends |
| Invest | Custodian manages investments on behalf of the child |
| Transfer | Ownership transfers to child at age of termination (18-25) |
| Spend | Child has full control and can use funds for anything |
Critical point: Once you contribute to a custodial account, it’s an irrevocable gift. You cannot take the money back, even if the child plans to spend it on something you disagree with.
Tax Rules (Kiddie Tax)
Earnings in a custodial account are taxed under the “kiddie tax” rules:
| Unearned Income (2026) | Tax Rate |
|---|---|
| First $1,300 | Tax-free |
| $1,301-$2,600 | Child’s tax rate (10%) |
| Over $2,600 | Parent’s marginal tax rate |
Tax Examples
| Account Balance | Investment Return (7%) | Annual Earnings | Tax Owed |
|---|---|---|---|
| $10,000 | $700 | $700 | $0 |
| $25,000 | $1,750 | $1,750 | ~$45 |
| $50,000 | $3,500 | $3,500 | ~$235-$500 |
| $100,000 | $7,000 | $7,000 | ~$860-$1,500 |
Tax depends on parent’s marginal rate for amounts above $2,600.
UGMA/UTMA vs. 529 Plan
| Feature | UGMA/UTMA | 529 Plan |
|---|---|---|
| Use of funds | Anything | Education only (or 35% penalty on earnings) |
| Tax on growth | Kiddie tax (partial) | Tax-free for education |
| Financial aid impact | Counted as student asset (20%) | Counted as parent asset (5.64%) |
| Contribution limits | No limit | $18,000/year gift tax exclusion (superfund 5 years) |
| Account maximum | No limit | $300K-$500K+ (varies by state) |
| State tax deduction | No | Yes (in ~34 states) |
| Rollover to Roth IRA | No | Yes (up to $35,000, starting 2024) |
| Age of transfer | 18-25 (irrevocable) | No age limit (parent controls) |
| Investment options | Any security | Limited plan options |
Choose UGMA/UTMA when: You want flexibility beyond education, or you’re investing for a child’s general use.
Choose 529 when: The money is specifically for college — better tax treatment and lower financial aid impact.
Impact on Financial Aid (FAFSA)
This is the biggest drawback of custodial accounts:
| Asset Type | FAFSA Treatment | Expected Family Contribution |
|---|---|---|
| Parent-owned assets (savings, 529) | 5.64% of value assessed | $5,640 per $100K |
| Student-owned assets (UGMA/UTMA) | 20% of value assessed | $20,000 per $100K |
| Student income (from account) | 50% of income assessed | Varies |
A $50,000 UGMA reduces financial aid eligibility by ~$10,000 (20% × $50K). The same $50K in a 529 only reduces aid by ~$2,820.
Termination Ages by State
| Termination Age | UGMA States | UTMA States |
|---|---|---|
| Age 18 | All states | CA, FL, GA, IL, IN, MA, MI, MN, MO, NC, OH, TX, VA, WI |
| Age 21 | N/A | AK, AZ, CO, CT, DE, DC, HI, ID, IA, KS, KY, LA, MD, MT, NE, NV, NH, NJ, NM, NY, ND, OK, OR, PA, RI, SD, TN, UT, WA, WV, WY |
| Age 25 | N/A | AL, AR, ME, MS |
Strategies and Best Practices
| Strategy | Details |
|---|---|
| Keep balances modest | $30K-$50K avoids significant kiddie tax and FAFSA impact |
| Invest in growth stocks (low dividends) | Minimize annual taxable distributions |
| Use for the child’s benefit first | Education, car, first apartment are common uses |
| Consider converting to 529 | Sell UGMA assets, contribute to 529 to reduce FAFSA impact |
| Open at birth for maximum growth | 18 years of compounding at 8% turns $10K into $40K |
