What a children's tax-advantaged account actually is
A children's tax-advantaged account is a savings account that lets you set aside money for a child's future expenses while reducing the taxes you owe on the growth. The money you put in is not tax-deductible — you cannot write it off on your tax return — but the earnings (interest, dividends, or investment gains) grow without being taxed each year. When the money comes out to pay for the child's education or other allowed expenses, you do not pay tax on those earnings either.
The most common version is a 529 plan, which is specifically for education costs. A second option is a Coverdell Education Savings Account (ESA), which also covers education but with lower contribution limits. A third is the Uniform Transfers to Minors Act (UTMA) account or Uniform Gifts to Minors Act (UGMA) account, which are more flexible — the money can be used for anything once the child reaches adulthood, but the tax treatment is less favorable.
The account belongs to the child, not to you, though you control it until they reach the age of majority (usually 18 or 21, depending on your state and the account type). If the money is not used for the allowed purpose, you will owe income tax plus a 10 percent penalty on the earnings — the contributions themselves come out tax-free.
Key Takeaways
- A 529 plan lets earnings grow tax-free and come out tax-free when used for education, making it the most common choice for college savings.
- You cannot deduct your contributions on your tax return, but you avoid paying taxes on the growth year after year.
- Each state runs its own 529 plan, and you can use any state's plan regardless of where you live or where the child will go to school.
- If money is withdrawn for non-education purposes, you owe income tax plus a 10 percent penalty on the earnings only, not on what you contributed.
- Coverdell ESAs and UTMA/UGMA accounts offer different flexibility and tax treatment, and which one makes sense depends on how much you plan to save and what you might use the money for.
How 529 plans work and what they cover
A 529 plan is a state-sponsored investment account. You open it through your state's plan (or another state's plan if you prefer), name the child as the beneficiary, and contribute money. The account then invests that money in mutual funds, stocks, bonds, or other options you choose. As the account grows, you pay no federal income tax on the gains each year, and most states do not tax the growth either.
When the child is ready to use the money, you can withdraw it for may have access to education expenses. These include tuition and fees at any accredited college, university, trade school, or graduate program in the United States or abroad. They also include room and board if the student is enrolled at least half-time, books, supplies, equipment, and up to $35,000 per year in student loan repayment (as of 2024, though this rule may change). Some plans now allow you to roll unused 529 money into a Roth IRA for the child, subject to limits.
You can open a 529 plan in any state, regardless of where you live or where the child will attend school. Each state's plan has different investment options and fee structures, so it is worth comparing a few. You can also change the beneficiary to another child in the same family if the first child does not use all the money.
Coverdell Education Savings Accounts and their limits
A Coverdell ESA is similar to a 529 but smaller in scale. You can contribute up to $2,000 per child per year (as of 2024), and the money grows tax-free. When withdrawn for may have access to education expenses — which include K-12 private school tuition as well as college costs — the earnings are not taxed.
The main trade-off is the contribution limit. If you want to save more than $2,000 per year, a 529 plan allows much larger contributions (often $235,000 or more per beneficiary, depending on the state). Coverdell accounts also have an income phase-out: if your modified adjusted gross income exceeds a certain threshold, you cannot contribute. For 2024, that threshold is $110,000 for single filers and $220,000 for married couples filing jointly, though these numbers change annually.
Coverdell accounts do allow K-12 expenses, which 529 plans do not (except in limited cases). If you are saving for private elementary or middle school, a Coverdell might be worth considering alongside a 529.
UTMA and UGMA accounts: more flexibility, less tax advantage
A UTMA (Uniform Transfers to Minors Act) or UGMA (Uniform Gifts to Minors Act) account is a custodial account that holds money or investments for a child. Unlike a 529 or Coverdell, there is no restriction on what the money can be used for — once the child reaches adulthood, they can spend it on anything. This flexibility appeals to parents who are uncertain whether the child will go to college or who want to leave options open.
The tax treatment is less favorable. The first $1,300 of earnings per year (as of 2024) is tax-free. The next $1,300 is taxed at the child's rate, which is usually lower than yours. Earnings above $2,600 are taxed at the parent's rate. This is called the "kiddie tax" rule. A 529 or Coverdell avoids this tiered tax structure entirely by deferring all tax until withdrawal.
Another consideration: when the child reaches the age of majority (18 or 21, depending on your state), the account becomes theirs to control. They can withdraw the money and use it however they want. With a 529 or Coverdell, you retain control and can prevent withdrawals for non-education purposes.
How contributions and withdrawals affect financial aid
If you are saving for college, the account type matters for financial aid calculations. Money in a 529 plan owned by a parent is counted as a parental asset and reduces financial aid may be able to access by about 5 percent of the account value per year. Money in a 529 owned by the student (or a grandparent) is treated differently and may reduce aid more significantly.
A Coverdell ESA is treated similarly to a 529 when owned by a parent. A UTMA or UGMA account, however, is counted as a student asset, which reduces aid may be able to access by up to 20 percent of the account value per year — a much steeper penalty. If you expect the child to receive need-based financial aid, a parent-owned 529 is usually the best choice.
Withdrawals from a 529 for education do not count as income to the child in the year of withdrawal, so they do not reduce aid in future years. This is another advantage over UTMA/UGMA accounts, where withdrawals are treated as the child's income.
Comparing the four account types side by side
| Account Type | Annual Contribution Limit | Tax on Growth | Allowed Uses | Who Controls the Money |
|---|---|---|---|---|
| 529 Plan | $235,000+ total per beneficiary (varies by state) | Tax-free if used for education | College, trade school, K-12 private school (limited), student loan repayment, Roth IRA rollover | You, until beneficiary reaches adulthood |
| Coverdell ESA | $2,000 per child per year | Tax-free if used for education | College, K-12 private school, may have access to education expenses | You, until beneficiary reaches adulthood |
| UTMA/UGMA | No limit (but gifts over $18,000 per year may trigger gift tax) | First $1,300 tax-free; next $1,300 at child's rate; above that at parent's rate | Anything, once child reaches adulthood | Child, once they reach age of majority |
When to use each account type
Use a 529 plan if you are saving for college or other post-secondary education and want the maximum tax benefit. It has the highest contribution limits, the best tax treatment, and the most control. If your state offers a tax deduction for 529 contributions (about 30 states do), that is an additional benefit. Open the account in your state's plan unless another state's plan has significantly lower fees or better investment options.
Use a Coverdell ESA if you are saving less than $2,000 per year and want to include K-12 private school tuition in your plan. If your income is above the phase-out threshold, you cannot use a Coverdell at all.
Use a UTMA or UGMA account if you want maximum flexibility and do not mind the less favorable tax treatment. This makes sense if you are uncertain whether the child will go to college, or if you want to leave the money to them to use as they see fit after they turn 18 or 21. Be aware that the child will have control of the account at that point.
Many families use a combination: a 529 for the bulk of college savings, and a UTMA or UGMA for smaller gifts from grandparents or other relatives who want to give the child flexibility.
Frequently Asked Questions
Can I change the beneficiary of a 529 plan if the child does not go to college?
Yes. You can change the beneficiary to another family member — a sibling, cousin, niece, or even yourself. If you change the beneficiary, no penalty applies. You can also roll unused 529 money into a Roth IRA for the original beneficiary, up to $35,000 lifetime, if the account has been open for at least 15 years.
What happens if I withdraw money from a 529 for something other than education?
You will owe income tax on the earnings portion of the withdrawal, plus a 10 percent penalty on those earnings. The contributions themselves come out tax-free. For example, if you contributed $10,000 and the account grew to $12,000, you would owe tax and penalty only on the $2,000 in earnings.
Do I have to use my state's 529 plan?
No. You can open a 529 plan in any state, regardless of where you live. However, some states offer a state income tax deduction for contributions to their own plan. Check whether your state offers this benefit before choosing a plan.
Can grandparents open a 529 for a grandchild?
Yes. Grandparents can open and contribute to a 529 plan for a grandchild. Be aware that a grandparent-owned 529 may have a larger impact on financial aid than a parent-owned one, so discuss this with a financial advisor if the child is likely to receive need-based aid.
What is the difference between a UTMA and a UGMA account?
UGMA accounts hold only cash, securities, and insurance. UTMA accounts can hold a wider range of assets, including real estate and artwork. UTMA is the newer standard and is available in all states; UGMA is older and available in most states. For most families saving for a child, the difference does not matter much.
