Saving and Investing for Grandchildren: Which Account Is Right?

Grandparents are often the single biggest source of a grandchild’s first real savings. A few thousand dollars given early — and left alone to compound for decades — can outgrow almost anything a busy young parent manages to set aside. The one decision that shapes how far that gift goes is which account it lands in, because that choice changes the taxes, who keeps control, and even the grandchild’s future college aid.

“Should I just open a savings account for my grandchild?”

It’s the most common instinct — and the most common question grandparents ask: can I open a savings account (or a bank account) for a grandchild? Yes, you can. A savings account is simple, safe, and familiar. But for money you’re setting aside to grow over 10 or 20 years, a plain savings account is usually the weakest option: its interest rarely keeps pace with inflation, so the money can quietly lose buying power while it sits.

The accounts below do the same “set money aside for a grandchild” job, but with decades of tax-advantaged growth instead of a low interest rate. The simple rule: a savings account is fine for money you’ll spend within a year or two; for anything longer-term, one of these will do far more with the same dollars. When you’re ready, here’s how to open an account for a grandchild, step by step.

The main options, side by side

The grandparent angles worth knowing

The FAFSA change that removed the “grandparent 529 penalty”

This is the big one. It used to be that money withdrawn from a grandparent-owned 529 counted as the student’s income on the FAFSA — which could cut aid sharply. Under the current FAFSA, that’s gone: grandparent-529 withdrawals are no longer reported as student income. That makes a grandparent-owned 529 one of the cleanest ways to help pay for college without denting aid. (See how custodial accounts affect financial aid for the full picture.)

Gifting limits — and “superfunding”

Contributions to any of these accounts are treated as gifts to the child. You can give up to the annual gift-tax exclusion per grandchild each year with no gift-tax paperwork — and a 529 has a unique “superfunding” move that lets you front-load several years of gifts at once. The exact figures change yearly, so confirm the current numbers with your tax advisor before a large gift. And if you’d rather give appreciated stock than cash, there’s a tax-smart way to do it.

Control: do you want a say in how it’s used?

If it matters to you that the money goes toward education rather than being handed over free and clear at 18, that points strongly to a 529 — you stay the owner indefinitely and can even change the beneficiary to another grandchild. A UTMA is the opposite trade: total flexibility on use, but the grandchild takes full control at the age of majority. If it really comes down to those two, we compare them head-to-head in Grandparent 529 vs. UTMA.

The part that makes a gift stick

Here’s the thing money in an account can’t do on its own: teach. A grandchild who can actually watch the account grow — see the balance, the holdings, the green days and red ones — connects the gift to you and to the whole idea of investing in a way a statement in a drawer never will. That visibility turns a generous deposit into a lesson they carry for decades. It’s the difference between giving a grandchild money and giving them a head start they understand.

Frequently asked questions

Can a grandparent open a savings account for a grandchild?

Yes. A grandparent can open a custodial savings account for a grandchild, or add money to one the parents opened. It's simple and safe, but for money meant to grow over many years, a 529, UTMA, or custodial Roth usually does far more with the same dollars than a savings account's interest rate.

Can a grandparent open a bank account for a grandchild?

Usually yes, though it varies by bank and many require a parent as joint owner or custodian. A bank account is fine for near-term money; for a long-term gift, a custodial investment account, a 529, or a custodial Roth typically builds far more over time.

How do I open an account for a grandchild?

You'll generally need the grandchild's Social Security number and, in some cases, a parent's involvement, plus a few minutes to open it online. Our step-by-step guide, How to Open an Account for a Grandchild, walks through the SSN wrinkle, who should be custodian, and funding.

What is the best account for a grandparent to invest for a grandchild?

It depends on the goal. A 529 is best for education because it grows tax-free and lets you keep control. A UTMA custodial account offers the most flexibility but transfers to the grandchild at 18 or 21. A custodial Roth IRA is powerful for long-term growth once the grandchild has earned income. Many grandparents use more than one.

Does a grandparent-owned 529 hurt financial aid?

Not anymore. Under the current FAFSA, withdrawals from a grandparent-owned 529 are no longer counted as the student's income, which removed the old 'grandparent 529 penalty.' That makes a grandparent-owned 529 one of the most aid-friendly ways to help.

How much can grandparents gift to a grandchild's account?

Contributions are treated as gifts to the child. You can give up to the annual gift-tax exclusion per grandchild each year with no gift-tax paperwork, and 529 plans allow 'superfunding' several years of gifts at once. The exact limits change yearly, so confirm current figures with a tax advisor.

Can a grandparent open a custodial Roth IRA for a grandchild?

Yes, if the grandchild has earned income from a job. The contribution is capped at what the child actually earned, and a grandparent can gift that contribution so the grandchild keeps their paycheck.

Can grandparents contribute to a grandchild's Trump Account?

Yes. For eligible children born 2025 through 2028, the federal program seeds $1,000, and grandparents and other family can contribute on top of it within the program's annual contribution cap once the contribution window opens.

The bottom line

There’s no single “right” account — there’s the one that fits your goal. Want it earmarked for college and kept under your control? A 529. Want maximum flexibility and don’t mind the handover at 18? A UTMA. Playing the longest possible game with a working teen? A custodial Roth. Whichever you choose, the gift does its best work when the grandchild can see it growing — which is exactly what MemoryBank shows them.
