What a custodial account does and why it matters for college
A custodial account is a savings or investment account held in a minor's name but controlled by an adult (the custodian) until the child reaches the age of majority—usually 18 or 21, depending on your state and the account type. The money belongs to the child, not the parent, which has real consequences for financial aid and taxes.
For college savings, custodial accounts let you invest money on behalf of a child and let it grow tax-deferred or tax-advantaged. The trade-off is that the money counts as the child's asset when you apply for federal financial aid, which can reduce aid may be able to access more than if the money were in a parent's name. You also lose control of the account once the child reaches the age of majority—they can withdraw it for any reason, not just college.
The two main types are UTMA/UGMA accounts (Uniform Transfers to Minors Act or Uniform Gifts to Minors Act) and 529 college savings plans. Both are custodial in structure, but they work differently and have different rules about what happens to unspent money.
Key Takeaways
- UTMA/UGMA accounts give the child full control at age 18 or 21, while 529 plans stay under your control and can be transferred to another family member if not used for college.
- Money in a custodial account counts as the child's asset on the FAFSA, which typically reduces federal financial aid more than money in a parent's account would.
- UTMA/UGMA accounts have lower contribution limits and simpler tax treatment, while 529 plans allow much larger contributions and offer state tax deductions in many states.
- If the child does not attend college, unspent money in a 529 can be rolled to a sibling or kept for graduate school, but UTMA/UGMA money becomes the child's to spend however they choose.
- The best choice depends on how much you plan to save, whether you want state tax benefits, and how comfortable you are with the child controlling the money at age 18 or 21.
UTMA and UGMA accounts: simpler but less control
An UTMA (Uniform Transfers to Minors Act) or UGMA (Uniform Gifts to Minors Act) account is a straightforward custodial brokerage or savings account. You open it at a bank or brokerage in the child's name with yourself as custodian. You can invest the money however you want—stocks, bonds, mutual funds, or keep it in cash. The child's Social Security number is on the account, and the earnings are taxed to the child each year.
The main limitation is the annual contribution limit. For 2024, you can give up to $18,000 per year per child without triggering federal gift tax (this amount changes yearly). If you give more, you have to file a gift tax return, though you likely will not owe tax unless you exceed your lifetime exemption. The account has no maximum balance—you can keep adding money year after year up to the annual limit.
The critical drawback is what happens at age 18 or 21 (depending on your state and whether it is UTMA or UGMA). The money becomes the child's property, and they can withdraw it for any reason—not just college. If they decide not to go to college or want to buy a car instead, you have no say. Some parents use this as motivation; others find it too risky.
529 college savings plans: more control and bigger tax breaks
A 529 plan is a state-sponsored investment account designed specifically for education savings. You open an account (usually through your state's plan, though you can use any state's plan regardless of where you live), name yourself as the account owner, and name the child as the beneficiary. You control the account for as long as you want—the child never takes control unless you transfer it to them.
Contributions to a 529 are not deductible at the federal level, but most states offer a state income tax deduction for contributions to their own plan. The amount varies by state—some states deduct up to $235,000 per beneficiary per year, while others deduct only $2,000 or $2,500. Check your state's plan to see what deduction you get. The money grows tax-free, and withdrawals for may have access to education expenses (tuition, fees, room and board, books, computers) are also tax-free.
You can contribute much more to a 529 than to an UTMA/UGMA. Most plans allow total contributions of $235,000 or more per beneficiary across all accounts. If the child does not use all the money for college, you have options: roll it to a sibling's 529, use it for graduate school, or (as of 2024) roll up to $35,000 of unused funds into the child's Roth IRA if certain conditions are met. The money does not automatically become the child's at any age.
How each account type affects financial aid
When you fill out the FAFSA (Free Application for Federal Student Aid), you report assets in the student's name separately from assets in the parent's name. Money in a custodial account—whether UTMA/UGMA or 529—counts as a student asset because the child's name is on it.
Student assets reduce financial aid may be able to access at a rate of roughly 20% of the asset value per year. So if a custodial account has $50,000, it reduces aid by about $10,000 per year. Parent assets reduce aid at roughly 5.64% per year, so the same $50,000 in a parent's name would reduce aid by about $2,820 per year. This is a significant difference, especially if the child will receive need-based aid.
If you have the choice between saving in your own name and opening a custodial account, saving in your own name is usually better for financial aid purposes. However, custodial accounts offer tax advantages (especially 529 plans with state deductions) that may outweigh the aid reduction. Run the numbers for your situation: calculate the state tax savings against the estimated reduction in aid.
Comparing the two account types side by side
| Feature | UTMA/UGMA | 529 Plan |
|---|---|---|
| Who controls the account | You until age 18–21, then the child | You, for as long as you want |
| Annual contribution limit | $18,000 per year (2024) | No annual limit; total per beneficiary usually $235,000+ |
| State tax deduction | None | Yes, in most states (amount varies) |
| Tax on growth | Taxed to child each year | Tax-free if used for education |
| What happens if not used for college | Child can spend it on anything at age 18–21 | Can roll to sibling, use for grad school, or roll to Roth IRA |
| Impact on financial aid | Counts as student asset (~20% reduction per year) | Counts as student asset (~20% reduction per year) |
| Investment options | Any stocks, bonds, funds at your brokerage | Pre-set investment portfolios (usually age-based or risk-based) |
Which account type fits your situation
Choose a 529 plan if you want to save a significant amount (more than $18,000 per year), you live in a state with a generous tax deduction, you want to keep control of the money past age 18, or you are comfortable with the idea that unspent money can be rolled to a sibling or used for graduate school. A 529 is also the better choice if you are unsure whether the child will attend a four-year college—you have more flexibility with the money.
Choose a UTMA/UGMA account if you are saving a small amount (under $18,000 per year), you want the simplicity of a regular brokerage account with full investment flexibility, you live in a state with no or low 529 tax deduction, or you want to give the child control of the money at age 18 as a way to teach financial responsibility. UTMA/UGMA accounts are also useful if you want to save for a child who may not go to college and you are comfortable with them having full access to the money as a young adult.
In practice, many families use both: a 529 for the bulk of college savings (to get the tax deduction and keep control) and a UTMA/UGMA for smaller gifts from grandparents or other relatives who want to give money directly to the child.
Tax treatment and what you owe each year
In a UTMA/UGMA account, the child pays tax on earnings each year. For 2024, the first $1,450 of earnings is tax-free (the child's standard deduction), the next $1,450 is taxed at the child's rate (usually 10%), and anything above that is taxed at the parent's rate (the "kiddie tax" rule). This means small accounts generate little or no tax, but large accounts can create a significant tax bill.
In a 529 plan, you pay no tax on earnings while the money is in the account. When you withdraw money for may have access to education expenses, the earnings come out tax-free. If you withdraw money for non-education purposes, the earnings portion is taxed to the child plus a 10% penalty (though the penalty was waived for certain circumstances in recent years—check current rules). The principal (money you contributed) always comes out tax-free.
For state taxes, a 529 contribution may reduce your state income tax in the year you contribute. The deduction is usually taken on your state tax return, not the child's. UTMA/UGMA accounts offer no state tax deduction.
Frequently Asked Questions
Can I change my mind and move money from a UTMA to a 529?
No, not directly. Money in a UTMA/UGMA is the child's property, so you cannot transfer it to a 529 without the child's consent (and at age 18+, they may refuse). You can, however, make new contributions to a 529 going forward. If you are starting from scratch, open a 529 instead of a UTMA/UGMA.
What if I open a 529 and the child gets a scholarship?
You can withdraw an amount equal to the scholarship from the 529 without the 10% penalty on earnings (though you still pay income tax on the earnings portion). The principal always comes out tax-free. This makes 529 plans safer than UTMA/UGMA accounts if a scholarship is a possibility.
Can I use a 529 for private school before college?
Yes. As of 2024, you can withdraw up to $35,000 lifetime from a 529 to pay for K-12 private school tuition. This is a relatively new rule, so check your plan's rules to confirm it is available.
Do I have to use the same state's 529 plan as where I live?
No. You can open a 529 in any state's plan, regardless of where you live or where the child goes to school. However, you only get the state tax deduction for contributing to your own state's plan (in most cases). Compare your state's plan to others to see which offers the best combination of tax deduction, investment options, and fees.
What happens to a 529 if the child decides not to go to college?
You can roll the money to a sibling's 529 at no penalty. You can also use it for graduate school, trade school, or apprenticeship programs. As of 2024, you can roll up to $35,000 into the child's Roth IRA if the account has been open for at least 15 years. If none of these options work, you can withdraw the money, but you will owe income tax and a 10% penalty on the earnings portion.
