Comparing Savings Accounts for Children and Grandchildren

Key Takeaways

• The account that fits depends less on how much you contribute and more on three factors: who controls the money, how it is taxed, and when the beneficiary can use it. That first factor surprises many families, since a custodial account like a UTMA passes to the child outright at 18 to 21, while a 529 owner keeps control for life.
• Earned income opens options many families overlook. A child with wages from a summer job can fund a custodial Roth IRA, where even modest contributions may compound tax-free for decades, while the newer Trump Account offers tax-deferred growth for a child who has no earned income yet.
• For grandparents, these accounts can double as estate planning tools. Annual gifts of up to $19,000 per recipient, or up to $95,000 into a 529 through the five-year election, may move meaningful assets out of a taxable estate, and coordinating several accounts across two generations is where a holistic financial plan earns its place.

When a child or grandchild arrives, the question of what to set aside financially tends to follow quickly. Open a 529? A custodial account? Start with annual gifts? Each option looks reasonable until the rules come into focus: who controls the funds, how contributions and withdrawals are taxed, and when the money becomes available to the beneficiary. Those differences can shape the outcome as much as the amount you contribute.

The clearest way to work through it is to start with your goal rather than the account. Once you know what you want the money to do, the options tend to narrow quickly and coordinating them becomes far more manageable.

Three questions to start with

Three questions sit underneath almost every one of these decisions:

• Who should control the funds, and for how long? Some accounts hand full control to the child at the age of majority. Others let the adult who opened the account stay in charge indefinitely.
• How do you want contributions and growth to be taxed? Options range from taxable custodial accounts to tax-deferred and potentially tax-free vehicles, each with its own conditions.
• When and how should the beneficiary be able to use the money? A few accounts restrict funds to education or retirement. Others place no strings on how the money is eventually spent.

Hold those three questions in mind as you read the goals below. Each account answers them differently, and there is rarely a single right answer. The best fit depends on your circumstances, which is worth reviewing with your tax and legal professionals before you fund anything.

If the goal is education

When education is the clear priority, a 529 plan is designed for exactly that. Growth is tax-deferred, and withdrawals are tax-free when used for qualified education expenses. Just as important for many families, the account owner keeps control indefinitely, even after the beneficiary becomes an adult, so the money stays directed toward its purpose. A 529 plan for a grandchild works the same way, which is one reason grandparents often use one to contribute toward education while keeping control of the account.

There is no IRS annual contribution limit, though contributions above $19,000 per donor in 2026 may require a gift tax return. Funds can be used for qualified higher-education costs, or up to $20,000 per year for K–12 tuition. Non-qualified withdrawals are taxed and may carry a 10 percent penalty on earnings, so a 529 fits families who are reasonably confident the money will go toward education. If that confidence is not there, the more flexible options further down may fit better.

If the goal is a head start on retirement

Two accounts are often used to give a child decades of tax-advantaged growth, and they suit very different situations.

A Roth IRA is available to a child who has earned income for the year, such as wages from a summer job. Contributions are after-tax and limited to the lesser of $7,500 in 2026 or the child’s own earned income. Those contributions can be withdrawn at any time free of tax and penalty, while earnings are meant to stay invested until retirement. For a child who is already earning, even modest contributions to a Roth IRA can compound tax-free for decades.

The Trump Account is one option when a child has no earned income yet. This federal program lets a parent or guardian manage the account until the beneficiary turns 18, with several options at that point, including an IRA rollover or Roth conversion. Contributions are made with after-tax dollars, growth is tax-deferred, and earnings are taxed as ordinary income when withdrawn. No earned income is required to open one. Contributions are capped at $5,000 per year combined, with the employer portion limited to $2,500, and children born between 2025 and 2028 may receive a one-time $1,000 federal deposit. In exchange for that access, the funds are locked until age 18 and restricted to low-cost index funds and ETFs during the growth period. This is one way a Trump Account differs from a custodial account such as a UTMA, which the child controls outright at the age of majority and can use for any purpose.

The choice between them often comes down to a single fact: whether the child has earned income. When they do, a Roth IRA offers more flexibility. When they do not, the Trump Account opens the same long-horizon opportunity.

If the goal is flexible gifting or transferring wealth

Some families are less focused on a single purpose and more on moving money to the next generation with room to adapt. A UTMA custodial account, one of the more flexible investment accounts available for a child, is one option for that goal. It can hold gifts for any purpose, not only education, and a custodian, often a parent, manages it until the child reaches the state-defined age of majority, generally 18 to 21. At that point the child gains full, unrestricted control of the assets, so a UTMA suits families comfortable with that handoff.

For families who want to keep control past that age, one alternative is a joint account the parents own and earmark for the child. They retain full authority and decide when to hand the money over. The trade-off comes later: transferring a large account to the child counts as a gift, which can raise gift or estate tax questions if the family has already used much of its lifetime exemption, the roughly $15 million per person that can be given away or left behind before those taxes apply. Keeping yearly gifts within the annual exclusion, $19,000 per donor in 2026 with no gift tax return required, helps manage that exposure.

For grandparents opening savings or investment accounts for grandchildren, gifting also opens a planning lens tied to legacy. In 2026, each donor can give up to $19,000 per recipient, or $38,000 per couple, before any gift tax return or use of the lifetime exemption comes into play. A grandparent with three grandchildren could give up to $19,000 to each in the same year, moving meaningful assets out of the taxable estate while funding the next generation. A 529 adds a further option here: a five-year election can allow up to $95,000 in a single year to be treated as spread across five years for gift-tax purposes, which can help seed an education fund and support an estate plan at the same time.

If the goal is insurance-based transfer

Of the five options, only variable universal life, or VUL, is built on a life insurance policy, which lets it do two things at once: provide a death benefit for heirs and build cash value the family can tap during life. A single policy can do both, though how it is funded shifts the emphasis. Funded to build cash value, it leans toward accumulation, with the death benefit remaining in place as a backstop. That cash value grows tax-deferred, and loans or withdrawals for the child may be income-tax-free while the policy stays in force, within IRS limits that keep it from being overfunded, known as modified endowment contract (MEC) testing. The owner, typically a parent or grandparent, keeps control of the policy and can gift it at any time, which is useful for passing wealth to the next generation. Because a VUL carries investment risk, including possible loss of principal, any purchase calls for a separate suitability review.

The options at a glance

Bringing it together

Few families are working toward only one of these goals, which is why these accounts are often used together. A 529 can carry the education plan while a Roth IRA compounds a working teenager’s earnings, and annual gifting can move assets to grandchildren while a UTMA or VUL handles what is left. The real work is fitting the pieces together so they reinforce your broader estate and tax plan, which is where a holistic financial planning process earns its place.

Frequently Asked Questions about Savings/Investment Accounts for Children or Grandchildren

What is a Trump Account?

 A Trump Account is a federal, tax-advantaged savings account for a child under 18, created under the One Big Beautiful Bill Act. A parent or guardian manages it until the child turns 18. Contributions are made with after-tax dollars, growth is tax-deferred, and no earned income is required to open one. Final Treasury regulations are still being issued.

Who is eligible for a Trump Account?

 A child under 18 with a valid Social Security number is eligible. Children born between 2025 and 2028 may also receive a one-time $1,000 federal deposit to help start the account.

How is a Trump Account different from a custodial account?

The main differences are control and access. A custodial account such as a UTMA passes to the child outright at the state age of majority and can be used for any purpose, while a Trump Account keeps funds locked until 18 and restricts them to low-cost index funds and ETFs during the growth period.

What can 529 funds be used for?

Qualified education expenses. That covers higher-education costs such as tuition, fees, books, and room and board, plus up to $20,000 per year for K–12 tuition in 2026. Non-qualified withdrawals are taxed and may carry a 10 percent penalty on earnings.

Can I open a Roth IRA for a grandchild?

Yes, as long as the grandchild has earned income for the year. The account is held as a custodial Roth IRA, and a grandparent can provide the funds, provided total contributions do not exceed the child’s earned income or the annual limit of $7,500 in 2026.

What is the best account to open for a grandchild?

It depends on your goal. A 529 plan fits education, a custodial Roth IRA suits a grandchild with earned income, and a UTMA places the fewest restrictions on how the money is used. Our advisors can help you match the account to your goal and coordinate it with the rest of your plan.
