Wealthfront Launches Tax-Efficient Custodial Account with $100 Seed Funding

PALO ALTO, Calif. — Wealthfront Corporation (Nasdaq: WLTH) has expanded its family wealth management lineup with a Custodial Account designed for parents saving for their children. The fintech announced the launch on June 23, 2026, alongside a promotion that gives clients $100 in seed funding when they open and fund a new Custodial Account or 529 Education Savings Plan by July 23, 2026.

CEO David Fortunato said the product aims to give children up to 18 additional years of market compounding and helps Wealthfront support clients as they start families. The account requires a $500 minimum and a 0.25% annual advisory fee. It is fully automated, handling portfolio construction, rebalancing and tax optimization within a globally diversified portfolio.

Tax-Gain Harvesting

The key differentiator is an automated Tax-Gain Harvesting strategy designed to take advantage of favorable federal tax treatment available to children. Wealthfront says it automatically sells appreciated exchange-traded funds each year while the child is in a low or 0% federal tax bracket, then buys replacement ETFs to maintain the portfolio's risk profile. The higher cost basis is intended to reduce future taxable gains when the child eventually withdraws the funds. Under the 2026 Kiddie Tax rules, the first $1,350 of a child's unearned income is tax-free; the strategy aims to realize up to that amount each year without requiring a federal tax return. Wealthfront notes the benefit depends on the beneficiary's total unearned income and state tax rules.

Custodial funds can be used for nearly anything that benefits the child, excluding basics such as food and housing, and there are no contribution caps or early withdrawal penalties. Control passes to the child at the age of transfer, typically 18 to 25 depending on the state. Wealthfront also positions the account as an option for parents who are ineligible for federal Section 530A 'Trump Accounts,' which Wealthfront does not offer, and for families saving for expenses beyond education or retirement. The company cautions that contributions are irrevocable gifts and that the accounts may reduce a child's eligibility for need-based financial aid.

Client data cited by Wealthfront shows parents are already active investors: those identified as parents hold an average of $91,000 across investment accounts, versus about $27,000 for clients without children. Clients who held a 529 account between June 1, 2021 and June 1, 2026 more than doubled their average balance to $60,000 from $30,000.

Dave Myszewski, VP of Product, said the Custodial Account gives families an automated, tax-efficient option for goals such as a down payment or a nest egg. The product complements Wealthfront's 529 plans and Joint and Trust Cash and Investing Accounts. The company said it plans to keep expanding, including its home-lending business and goal-based saving features in its Cash Account, which currently earns up to 4.20% APY through incentives.
