Grandparent 529 vs. UTMA: Which Is Better for a Grandchild?
529 or UTMA for a grandchild? Control vs. flexibility, the tax and financial-aid differences, and a simple rule for choosing between them.
For a grandparent investing for a grandchild, the choice usually comes down to two accounts: a 529 plan or a custodial account (UTMA). They look similar from the outside but behave very differently.
The core difference
A 529 is built for education, grows tax-free for school costs, and lets you keep control. A UTMA is flexible — usable for anything that benefits the child — but it becomes the child's money at adulthood.
| 529 plan | UTMA (custodial) | |
|---|---|---|
| Use of funds | Education (non-education use is taxed + penalized on earnings) | Anything that benefits the child |
| Who controls it | You (the grandparent) keep control | Custodian, until the child reaches the age of majority |
| Whose money | Yours, with the grandchild as beneficiary (changeable) | The child's — an irrevocable gift |
| Tax on growth | Tax-free for qualified education | Taxed in the child's name (watch the kiddie tax) |
| Financial aid | Grandparent-owned 529 distributions no longer count against aid (newer FAFSA) | Counts as the student's own asset (weighs more) |
The financial-aid update that changed the math
Financial aid used to be the big knock against grandparent 529s. Not anymore: under the newer FAFSA rules, distributions from a grandparent-owned 529 no longer count as student income against aid. A UTMA, by contrast, is treated as the student's own asset. See custodial accounts & financial aid for the details.
Aid and tax rules change and vary by state — MemoryBank is an education and display tool, not a financial advisor. Confirm the current rules with a professional.
A simple way to choose
- Goal is education + you want control? The 529 is usually the cleaner fit.
- Want maximum flexibility and fine handing over control at adulthood? The UTMA fits.
- Want both? Many grandparents use a 529 as the core and a smaller UTMA for flexibility.
What to do this week
- Decide whether education-only (529) or full flexibility (UTMA) matters more to you.
- Check your state's 529 for any tax deduction on contributions.
- Open the account and coordinate the SSN with the parents.
