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

Key Takeaways

  1. UGMA holds financial assets; UTMA adds real estate and other assets — UTMA is more flexible
  2. Contributions are irrevocable gifts — the child gets full control at age 18-25 depending on state
  3. The kiddie tax shelters the first $2,600 of earnings — above that, earnings are taxed at the parent’s rate
  4. UGMA/UTMA assets reduce financial aid eligibility by 20% vs. 5.64% for parent-owned 529 plans
  5. Best for non-education goals or flexible savings — choose 529 if money is specifically for college
  6. Learn about 529 plans for dedicated education savings with better tax treatment

How to Open a UGMA/UTMA Account

Opening a custodial account takes about 10-15 minutes at most online brokerages:

  1. Choose a brokerage — Fidelity, Schwab, and Vanguard all offer custodial accounts with no minimums and no management fees
  2. Provide your information — As the custodian, you’ll provide your SSN and personal details
  3. Provide the child’s information — Child’s name, date of birth, and Social Security number
  4. Fund the account — Link a bank account and make an initial deposit (as low as $1 at most brokers)
  5. Start investing — Index funds and ETFs are the most common choice for long-term growth

The child’s SSN is required — if they don’t have one, apply with the Social Security Administration first.

Brokerage Account Minimum Annual Fees Best Feature
Fidelity $0 $0 Fractional shares, no fees
Charles Schwab $0 $0 Strong research tools
Vanguard $0 $0 Index fund specialists
E*TRADE $0 $0 Easy interface
TD Ameritrade (Schwab) $0 $0 Education resources

What to Invest in a UGMA/UTMA Account

Because the account is long-term (typically 15-20 years until transfer), growth-oriented investments make the most sense:

Investment Type Annual Return (hist. avg) Tax Efficiency Best For
Total stock market index fund ~10% High (low dividends) Maximum long-term growth
S&P 500 ETF (VOO, SPY) ~10% High Simple, diversified growth
Growth ETFs ~11% High Higher risk, higher reward
Dividend stocks/ETFs ~8-9% Lower (kiddie tax issue) Income-focused (less ideal)
Bonds ~4-5% Medium Reduce volatility (rarely appropriate)

Tax efficiency tip: Favor growth-oriented investments with low dividends. Dividends are taxed annually under the kiddie tax rules. Capital gains are only taxed when you sell, giving you more control over the timing.

Growth Projection: $10,000 Invested at Birth

Child’s Age Balance at 8% Annual Return
1 year $10,800
5 years $14,693
10 years $21,589
15 years $31,722
18 years $39,960
21 years $50,338

Monthly contributions amplify this dramatically. $100/month from birth to age 18 = ~$45,000 at 8% returns.

UGMA/UTMA Tax Strategy

Use the annual gift tax exclusion. In 2026, you can contribute up to $19,000 per child without filing a gift tax return. Married couples can give $38,000 per year per child. Contributions above this use your lifetime exemption ($13.99 million).

Harvest losses when possible. If investments are down, selling and immediately reinvesting resets your cost basis and books a capital loss — reducing the child’s taxable income.

Consider the transfer age. If your state allows UTMA termination at 21 (not 18), the child has 3 extra years before gaining control — potentially useful if you’re worried about financial maturity.

No conversion to 529. Unlike some other account types, you cannot directly roll a UGMA/UTMA into a 529 plan. To change, you’d need to liquidate the custodial account (triggering taxes), then contribute the proceeds to a 529. This may still be worthwhile if the FAFSA timing makes it beneficial.
