How to open a Vanguard custodial account

Opening a Vanguard custodial account is a quick and easy process. You'll need some basic documentation, as well as a source of funds for the account.

Required documentation for a Vanguard custodial account

Before you open a Vanguard custodial account, you'll need to gather some basic information:

  • Date of birth
  • Legal name
  • Physical address
  • Social Security number
  • Successor custodian information
  • Trustee certification form (if naming a trust as the custody agent)

It's also worth noting that you'll need information for both the custodial (the person opening the account), as well as the account owner (the minor).

Setting up a Vanguard custodial account

Setting up a Vanguard custodial account for a child is a quick process, and involves three basic steps:

  • Enter information about you as the custodian. If you don't already have a Vanguard account, you'll also need to set up a Vanguard login.
  • Enter information about the minor and choose the state whose rules will govern the account. This can be where the custodian or minor lives, or the residence of someone else contributing money to the account.
  • Sign agreements and link a bank account to contribute money to the custodial account.

Investment strategies for custodial accounts

Money in a custodial account can be invested in virtually any stocks, bonds, mutual funds, ETFs, money market funds, or CDs offered by a particular broker. Without getting into specific investments to buy in a UGMA or UTMA custodial account, there are some general strategies to keep in mind:

  • Focus on the long term: The main goal of custodial account investing is to give a minor a head start on growing a nest egg, so it would be wise to focus on investments to hold for years to come (as opposed to trying to invest in what is going to do well this year).
  • Diversify: There are several ways to create a diversified portfolio in a custodial account. This can mean buying a few dozen stocks, or it can be as simple as investing the money in broad-based index funds.
  • Tax efficiency: Any gains or income generated within a custodial account can be considered taxable income to the minor, not to you. Since minors generally have a low tax rate (often 0%), investing in a UGMA/UTMA account can be a tax-efficient place to hold income investments.

What is a Vanguard custodial account?

A Vanguard custodial account can be opened under the Uniform Gifts to Minors Act (UGMA) or Uniform Transfers to Minors Act (UTMA). The account can be opened under the rules of any of the 50 states, and the age of majority or age at which the custodianship ends depends on the state's rules.

Accounts may be opened as:

  • UGMA (Uniform Gifts to Minors Act)
  • UTMA (Uniform Transfers to Minors Act)

For most purposes, these account types are identical. The biggest difference between the two is that UGMA accounts are designed to hold cash, stocks, bonds, and mutual funds, while UTMA accounts can hold a wider range of assets, including things like real estate, patents, royalties, and more. But for those opening a custodial account through a broker like Vanguard, they are essentially the same thing.

FAQs

  • Yes, Vanguard offers both UGMA and UTMA custodial accounts to allow adults to invest on behalf of minors. Vanguard also offers 529 plans to allow parents and other adults to save and invest for the specific purpose of paying for education.

  • Once the account owner (child) turns 18, or whatever the age of majority is in their state, the custodianship of the account terminates. In some situations, the custodian can choose between certain ages for the custodianship to terminate (18 and 21 are common choices). Once this happens, the account simply becomes an ordinary brokerage account controlled by the named account owner.

  • There are two major differences between Vanguard custodial accounts and 529 plans. First, 529 plans are used to save and invest for a specific purpose (education), while investments in a custodial account can be used for any purpose. Second, assets in a 529 plan are the legal property of the parent, or whomever opens the account. Assets in a custodial account are the legal property of the minor.
