Wealthfront Expands Investment Access with New Custodial Account Offering
Wealthfront has officially launched custodial accounts, allowing parents and guardians to open investment portfolios on behalf of minors. The new offering, announced by the company in late 2024, enables users to automate investments in low-cost, diversified index funds while maintaining control of the assets until the beneficiary reaches the age of majority. This move targets the growing demand for automated wealth management tools designed to build long-term generational wealth.
How Wealthfront Custodial Accounts Work
A custodial account, often referred to as a UTMA (Uniform Transfers to Minors Act) or UGMA (Uniform Gifts to Minors Act) account, allows an adult to manage assets for a child. According to U.S. Securities and Exchange Commission (SEC) guidelines, these assets are legally owned by the minor, but the custodian manages the account until the child reaches the age of majority, which varies by state—typically between 18 and 25.

Wealthfront’s implementation automates the investment process by applying its signature robo-advisory strategy. Once funds are deposited, the platform allocates the capital into a diversified portfolio of exchange-traded funds (ETFs) based on the child’s age and the expected timeline for the funds. The company charges its standard annual advisory fee of 0.25% on these accounts, consistent with its existing Automated Index Investing service.
Key Differences Between Custodial Accounts and 529 Plans
Investors often weigh custodial accounts against 529 college savings plans. While both are vehicles for saving for a child’s future, they differ significantly in their tax treatment and usage flexibility.
| Feature | Custodial Account (UTMA/UGMA) | 529 Plan |
|---|---|---|
| Usage | Any purpose benefiting the minor | Education-related expenses only |
| Tax Treatment | Subject to “kiddie tax” rules | Tax-free growth for education |
| Ownership | Owned by the minor | Owned by the account holder |
As noted by Internal Revenue Service (IRS) regulations, income generated within a custodial account may be subject to the “kiddie tax,” where a portion of the earnings is taxed at the parent’s marginal rate rather than the child’s lower rate. Unlike 529 plans, which offer tax-free withdrawals for qualified education expenses, custodial accounts provide no specific tax advantages, but they offer greater flexibility regarding how the funds are ultimately spent.
Why Automated Investing for Minors Is Growing
The introduction of this product reflects a broader trend in fintech: simplifying the transition of wealth to the next generation. Wealthfront’s automated approach removes the need for manual stock picking or constant rebalancing, which historical data suggests can be a barrier for parents who lack deep financial expertise.
By integrating custodial accounts into its existing ecosystem, Wealthfront aims to capture long-term assets. When the minor reaches the age of majority, the assets are transferred to an individual account in their name. This strategy aligns with the company’s goal of becoming a primary financial hub for households, moving beyond simple retirement or individual brokerage accounts to cover the entire family’s financial lifecycle.
Frequently Asked Questions
Can I open a custodial account if I am not the parent?
Yes. According to FINRA, any adult can open a custodial account for a minor. The custodian does not need to be a parent, though they must manage the assets strictly for the benefit of the minor.

What happens to the account when the child turns 18?
At the age of majority, the custodian’s authority over the account terminates. The assets legally belong to the beneficiary, and they gain full control over the funds, including the ability to withdraw or reallocate them as they see fit.
Is there a minimum deposit required?
Wealthfront requires a minimum deposit of $500 to start an investment account, a threshold that applies to its new custodial offerings as well, according to the company’s official FAQ page.
