Custodial Account
Quick Definition
A financial account managed by an adult on behalf of a minor, with assets transferring to the child at the age of majority.
Key Takeaways
- Assets in custodial accounts are irrevocable gifts — they belong to the child
- The child gains full control at age of majority (18 or 21 by state)
- Custodial accounts count as student assets for FAFSA, reducing financial aid by up to 20%
- Unlike 529 plans, custodial accounts have no restrictions on how funds are spent
What Is Custodial Account?
A custodial account is a savings or investment account established by an adult (custodian) for the benefit of a minor child. The two main types are UGMA (Uniform Gifts to Minors Act) and UTMA (Uniform Transfers to Minors Act) accounts. The custodian manages the account and makes investment decisions until the minor reaches the age of majority (18 or 21, depending on the state), at which point the assets transfer irrevocably to the child. Custodial accounts offer flexibility in how funds can be used (not limited to education like 529 plans), but they can affect financial aid eligibility and the child gains full control regardless of maturity level.
Custodial Account Example
- 1A grandparent opens a UTMA account and invests $5,000 in index funds for a newborn, potentially growing to $40,000+ by age 18.
- 2The first $1,350 of unearned income in a custodial account is tax-free for the child (2026), with the next $1,350 taxed at the child's rate.
- 3A parent uses custodial account funds to pay for a teenager's car, which is permitted since UTMA allows any expenditure benefiting the minor.
