Custodial Accounts vs 529 Plans For College
Compare custodial accounts and 529 college savings plans to choose the best way to invest for your child’s education and future.
An Overview of Custodial Accounts and 529 College Savings Plans
Saving for a child’s future can feel overwhelming, especially when you are trying to balance today’s expenses with long-term goals like college, first-car money, or a down payment on a home. Two of the most common tools families use are custodial accounts and 529 college savings plans. Understanding how each works, their tax treatment, and their pros and cons will help you decide which option (or combination of options) is best for your family.
What is a custodial account?
A custodial account is a financial account that an adult manages for a child until the child reaches the legal age of majority in their state. These accounts are usually created under state laws known as the Uniform Gifts to Minors Act (UGMA) or the Uniform Transfers to Minors Act (UTMA).
In a custodial account:
- The child (minor) is the legal owner of the assets.
- An adult (often a parent or guardian) acts as the custodian who manages the money or investments.
- The custodian controls the account until the child reaches the age of majority (often 18 or 21, depending on state law).
Custodial accounts can be opened at banks, credit unions, or brokerage firms, and they can hold cash, stocks, bonds, mutual funds, and other investments.
UGMA vs UTMA: the two main types
Most custodial accounts are either UGMA or UTMA accounts, depending on your state.
- UGMA (Uniform Gifts to Minors Act) accounts typically allow financial assets like cash, stocks, bonds, and mutual funds.
- UTMA (Uniform Transfers to Minors Act) accounts can hold everything UGMA accounts can hold, plus some additional property such as certain real estate or other assets, depending on state law.
Each state sets its own rules for UGMA/UTMA, including the age at which the child gains full control of the account.
How custodial accounts work
Once a custodial account is opened, the process is relatively straightforward.
Who owns and controls the money?
- Ownership: The child is the beneficial owner of the assets from day one. The money is considered an irrevocable gift to the child and cannot be taken back by the donor.
- Control: The custodian manages contributions, investments, and withdrawals until the child reaches the age of majority set by state law.
What can the money be used for?
Unlike education-specific accounts, custodial account funds can be used for almost any expense that benefits the child, such as:
- Extracurricular activities and camps
- Private school or tutoring
- Technology or equipment the child needs
- College costs and other education expenses
- Major purchases like a first car or moving costs
The key rule is that withdrawals must be used for the child’s benefit, not for the custodian’s personal use.
When does the child get full control?
Once the child reaches the age of majority (commonly 18 or 21, and in some states 19 or even up to 25), the account must be turned over to them. At that point, they can use the money for any purpose at all, even if the original intent was to fund college.
Tax treatment of custodial accounts
Custodial accounts can offer some tax advantages compared with investing in the parent’s name, but they are not as tax-favored as dedicated education accounts like 529 plans.
How investment income is taxed
- Income (interest, dividends, capital gains) in a custodial account is generally taxed to the child, not the parent.
- Under the so-called “kiddie tax” rules, a portion of a child’s unearned income may be taxed at the child’s lower rate, while income above a set threshold is taxed at the parents’ rate.
- Contributions are not tax-deductible for the person funding the account.
Gift and estate tax considerations
Money or property transferred into a custodial account is considered a completed gift to the child. This means:
- Gifts at or below the IRS annual gift tax exclusion amount per donor, per child, generally do not trigger gift tax.
- Larger gifts may require filing a gift tax return and could reduce the donor’s lifetime gift and estate tax exemption.
Pros and cons of custodial accounts
Custodial accounts are flexible, but they also come with trade-offs. Here are some key advantages and disadvantages.
| Pros of Custodial Accounts | Cons of Custodial Accounts |
|---|---|
| Easy to open and maintain, similar to a regular bank or brokerage account. | Assets legally belong to the child and are irrevocable; you cannot take them back or change beneficiaries. |
| Very flexible use of funds: can be used for any expense that benefits the child, not just education. | Once the child reaches the age of majority, they gain full control and can spend the money however they choose. |
| No specific income limits or contribution caps; anyone can contribute. | Investment income is subject to kiddie tax rules and is not tax-free or tax-deferred like a 529 for qualified education expenses. |
| Potential income tax savings because some unearned income may be taxed at the child’s lower rate. | Because the assets are in the child’s name, they may reduce eligibility for need-based financial aid more than some parent-owned accounts. |
What is a 529 college savings plan?
A 529 plan is a tax-advantaged savings plan designed to help families save for education costs. These plans are sponsored by states or educational institutions and are authorized under Section 529 of the Internal Revenue Code. Most common are 529 college savings plans, which work similarly to investment accounts and offer tax benefits when the money is used for qualified education expenses.
How 529 plans work
- You open a 529 account and name a child (or another individual) as the beneficiary.
- You choose an investment option (often age-based portfolios or static portfolios) offered by the plan.
- The account grows tax-deferred, and withdrawals for qualified education expenses are generally tax-free at the federal level and often at the state level when state rules are met.
- The account owner (often a parent) keeps control of the account, even after the beneficiary becomes an adult.
What can 529 money be used for?
Within federal and plan rules, 529 funds can be used for a wide range of qualified education expenses, such as:
- Tuition and required fees for college, university, or eligible postsecondary programs
- Books, supplies, and certain equipment
- Room and board (for students enrolled at least half-time)
- Some K–12 tuition costs, subject to federal and state limits
- Approved apprenticeship program expenses
Using 529 funds for non-qualified expenses generally triggers income tax on earnings plus an additional federal penalty tax on the earnings portion of the withdrawal.
Tax benefits of 529 plans
529 plans are popular largely because of their tax treatment.
- Tax-deferred growth: Investment earnings in a 529 plan grow tax-deferred.
- Tax-free withdrawals: When used for qualified education expenses, withdrawals are generally tax-free at the federal level and may be tax-free at the state level, depending on your state of residence and its rules.
- State tax benefits: Many states offer tax deductions or credits on contributions to their own 529 plans.
- Estate planning advantages: Contributions are treated as completed gifts to the beneficiary, and special rules allow you to front-load up to five years’ worth of annual gift tax exclusions in one year for 529 contributions, subject to IRS limits.
Custodial accounts vs 529 plans: key differences
Both custodial accounts and 529 plans can be used to invest for a child’s future, but they’re structured very differently. Here is a side-by-side comparison:
| Feature | Custodial Account (UGMA/UTMA) | 529 College Savings Plan |
|---|---|---|
| Ownership | Assets legally belong to the child; custodian manages until majority. | Account owned by the parent (or other adult); beneficiary is the child. |
| Use of funds | Can be used for any expense that benefits the child, education or otherwise. | Must be used for qualified education expenses to maintain tax benefits. |
| Tax advantages | Some unearned income may be taxed at the child’s rate; no special tax-free withdrawal for education. | Tax-deferred growth and generally tax-free withdrawals for qualified education expenses. |
| Control at adulthood | Child gains full control at age of majority; donor cannot change beneficiary. | Account owner maintains control and can change beneficiaries in many cases. |
| Financial aid impact | Treated as the child’s asset and may reduce need-based aid more. | Typically treated as a parent asset (when parent-owned), which generally has a smaller impact on aid. |
| Contribution limits | No formal contribution cap, but gifts are subject to gift tax rules. | Plans have high aggregate limits; contributions subject to gift tax rules but can use 5-year front-loading. |
How to choose between a custodial account and a 529 plan
Your decision will depend on your priorities, your child’s goals, and your comfort with giving up control of the assets at a certain age.
When a custodial account might make sense
You might lean toward a custodial account if:
- You want maximum flexibility for how the money can be used (education, business start-up funds, down payment, etc.).
- You are comfortable with the child gaining full control at the age of majority.
- You want family and friends to be able to contribute easily without worrying about specific plan rules.
When a 529 plan might be a better fit
A 529 plan may be more appropriate if:
- Your primary goal is to save for education costs.
- You want to maximize tax advantages, especially tax-free withdrawals for qualified education expenses.
- You prefer to retain long-term control over how and when the money is used.
- You want the option to change the beneficiary if one child does not need the funds.
Using both together
Many families choose to use both a custodial account and a 529 plan:
- Use the 529 plan for expected education costs where tax-free withdrawals can provide significant savings.
- Use the custodial account for non-education goals or as a way to give your child more flexible funds for adulthood.
Steps to open a custodial account
If you decide a custodial account fits your goals, the process is typically simple.
- Choose a financial institution (bank, credit union, or brokerage) that offers UGMA/UTMA accounts and investment options you like.
- Gather required information, such as the child’s legal name, date of birth, and Social Security Number or Taxpayer Identification Number.
- Complete the account application, naming yourself (or another adult) as custodian and the child as beneficiary.
- Fund the account with an initial deposit and set up recurring contributions if desired.
- Select appropriate investments based on your time horizon and risk tolerance.
FAQs about custodial accounts and 529 plans
Q: Can I change the beneficiary on a custodial account?
A: No. Once you establish a custodial account for a specific child, the assets legally belong to that child and you generally cannot change the beneficiary to someone else.
Q: What happens to a custodial account when my child becomes an adult?
A: When the child reaches the age of majority under state law, you must transfer control of the account to them. At that point, they can use the money for any purpose, not just education.
Q: Can custodial account money be used for college?
A: Yes. Custodial account funds can absolutely be used for college and other educational expenses, as long as the spending benefits the child. The main difference is that there is no special tax break for education-related withdrawals, unlike a 529 plan.
Q: What if my child doesn’t go to college and I have money in a 529 plan?
A: If your child does not use the 529 funds for qualified education expenses, you can typically change the beneficiary to another eligible family member. If you choose to withdraw the money for non-qualified purposes, you will owe taxes on the earnings plus an additional federal penalty tax on the earnings portion.
Q: Can grandparents contribute to either type of account?
A: Yes. Grandparents and other relatives can contribute to both custodial accounts and 529 plans, subject to general gift tax rules. In a custodial account, their contributions become irrevocable gifts to the child. In a 529 plan, they can either open their own account or contribute to one owned by a parent.
Q: Do I have to choose just one type of account?
A: No. Many families use a combination strategy—funding a 529 plan to cover anticipated education expenses and using a custodial account for broader goals or additional flexibility.
