A Charles Schwab custodial account (UGMA/UTMA) lets parents and guardians invest on behalf of a minor child. Schwab offers these accounts with no minimum balance, $0 stock and ETF commissions, and access to its full range of investments — including Schwab’s own low-cost ETFs like SCHB (0.03%) and SCHD (0.06%).

What Is a Schwab Custodial Account?

A Schwab custodial account is a brokerage account opened under the Uniform Gifts to Minors Act (UGMA) or Uniform Transfers to Minors Act (UTMA). The adult custodian manages the account until the child reaches the age of majority — typically 18 in most states, up to 21 in some states under UTMA — at which point assets transfer outright to the child.

Key features:

  • Mutual funds — thousands of no-transaction-fee mutual funds

  • Options — subject to custodian approval and appropriate account permissions

Best Schwab ETFs for a Custodial Account

A simple two-fund portfolio for a child: SCHB (US stocks) + SCHF (international stocks) at a combined cost of 0.03%–0.06% per year.

Tax Rules for Schwab Custodial Accounts

Custodial accounts are taxable. The Kiddie Tax applies to unearned income (dividends, capital gains) for children who are dependents under 19 (or under 24 if a full-time student):

Income tier (2026) Tax rate
First $1,300 unearned income 0% (tax-free)
Next $1,300 Child’s marginal rate (usually low)
Above $2,600 Parent’s marginal tax rate

Practical impact: For small accounts generating limited dividends, Kiddie Tax is minimal. For large accounts or high-yield strategies, it can be significant.

Schwab Custodial Account vs. Schwab 529 Plan

Feature Custodial account 529 Plan
Tax on growth Taxable (Kiddie Tax) Tax-free if used for education
Use of funds Any purpose Education (or 10% penalty)
Control after majority Child owns outright Parent retains control
FAFSA impact Up to 20%/year Up to 5.64%/year
Investment flexibility Unrestricted Plan options only

For college savings, a 529 plan is usually more tax-efficient. For general wealth transfer to a child (not specifically for education), a custodial account offers more flexibility.

FAFSA Impact

Custodial account assets count as the student’s assets on the FAFSA, reducing financial aid eligibility by up to 20% of the account value per year. This is more impactful than a parent-owned 529 plan (5.64% per year). Families expecting to need financial aid should weigh this carefully.

Worked Example: Starting a Custodial Account at Birth

A grandparent opens a Schwab custodial account for a newborn and contributes a one-time $5,000, then $100/month in SCHB (US Total Market, 0.03%):

Age Total contributions Estimated value at 7% annualised
5 $11,000 ~$16,500
10 $17,000 ~$32,000
18 $26,600 ~$72,000

At 18, $72,000 transfers to the child — an 18-year head start on wealth building.

How to Open a Schwab Custodial Account

  1. Log in to Schwab (or create an account at schwab.com)
  2. Navigate to “Open an Account” → “Custodial Account”
  3. Provide your information as custodian and the minor’s Social Security Number
  4. Fund the account via bank transfer, check, or transfer from another account
  5. Select investments — SCHB is a simple, low-cost starting point

Bottom Line

A Charles Schwab custodial account is an excellent vehicle for investing on behalf of a child. With $0 minimums, $0 commissions, and access to Schwab’s own ultra-low-cost ETF lineup, you can build a well-diversified portfolio at minimal cost. The main considerations are the FAFSA impact (counts as student asset) and the irrevocability — once assets are contributed, they belong to the child. For families focused on long-term wealth building rather than financial aid optimisation, Schwab’s custodial account is a compelling choice.
