Yes. A grandparent can open a 529 plan and both shrink a grandchild's future college bill and, since a 2024 rule change, stop costing that grandchild financial aid.
A 529 plan is a tax-advantaged savings account meant for education costs, and when a grandparent owns rather than merely contributes to one, the rules now work mostly in the family's favor. The savings come from three separate places: a federal financial-aid rule that used to penalize these accounts, a federal gift-tax allowance large enough to front-load years of contributions at once, and in some states, a state income-tax deduction on top of all of it. None of those benefits requires the grandparent to do anything unusual — just open an account in their own name and fund it.

Why the FAFSA Rule Change Matters
For years, the standard advice was for grandparents to avoid owning a 529 plan outright, because withdrawals counted as the student's untaxed income on the FAFSA, the federal aid application most colleges require. That income hit could cut need-based aid by as much as half of the amount withdrawn. Starting with the 2024-25 FAFSA cycle, that penalty disappeared: distributions from a grandparent-owned 529 plan are no longer reported as student income at all, under the FAFSA Simplification Act, according to SavingForCollege.
The account itself got easier to hold, too. A grandparent-owned 529 isn't reported as a student or parent asset on the FAFSA in the first place, unlike a custodial account or UTMA, because the grandparent — not the student — controls the money, SavingForCollege notes. That combination — invisible as an asset, and no longer penalized as income when spent — is what turned grandparent ownership from a liability into an advantage.
Where the Advantage Doesn't Apply
The FAFSA fix doesn't reach every school. More than 200 private colleges require the CSS Profile, a separate financial-aid application, and those schools can still ask about grandparent-owned 529 assets and distributions and count them against aid, according to Grown and Flown.
If a grandchild is applying to one of these schools, the FAFSA-only fix doesn't apply, and the grandparent-owned account can still reduce aid eligibility the old way. Before opening an account with aid in mind, it's worth checking whether the schools on the grandchild's list use the CSS Profile. A quick way to check: most CSS Profile schools are selective private colleges and universities, and each one lists the requirement on its own financial-aid page.
How Much Can a Grandparent Put In?
Beyond the aid rules, a 529 plan lets a grandparent move a large amount of money at once without triggering gift tax. The federal annual gift-tax exclusion for 2026 stays at $19,000 per recipient, the IRS confirmed in its 2026 inflation adjustments, while the lifetime estate-and-gift exemption rises to $15,000,000 per person under the One Big Beautiful Bill Act.
A 529 plan has a special rule, often called superfunding, that lets a grandparent elect on IRS Form 709 to treat one large gift as if it were spread over five years. That means a single grandparent can put up to $95,000 into one grandchild's 529 in a single year for 2026, or married grandparents up to $190,000, by using five years' worth of the $19,000 exclusion at once, SavingForCollege explains. The money still has to sit in the plan for the full five years to avoid gift-tax consequences if the grandparent later makes more gifts to the same grandchild.
- Deciding between a one-time large deposit and smaller yearly contributions depends mostly on timeline: superfunding suits a grandparent who wants the money invested and growing for a decade or more, not one covering costs for a grandchild starting college next year.
Does Opening the Account Bring a State Tax Break?
A state income-tax deduction for 529 contributions isn't automatic, and it isn't available everywhere. California, Hawaii, Kentucky, and North Carolina offer no state deduction at all for 529 contributions, and many states that do offer one restrict it to the account's legal owner rather than any contributor, SavingForCollege reports.
That ownership restriction matters directly for grandparents. In Massachusetts, only the account owner can claim the state deduction — up to $1,000 for a single filer or $2,000 for joint filers per year — so a grandparent who simply contributes to a parent-owned account gets nothing, and has to open a separate account in their own name to claim it, according to a SavingForCollege guide for Massachusetts grandparents. New York works differently: its state deduction, up to $5,000 for single filers or $10,000 for joint filers per year, has no restriction tied to the owner's or beneficiary's age or relationship, so a grandparent who owns the account qualifies just as a parent would, per the Office of the New York State Comptroller.
- Before contributing to an existing parent-owned account, check whether the state's deduction is tied to account ownership — if it is, a grandparent needs their own account to get the tax break at all.
What If the Money Isn't All Spent on College?
A long-standing objection to 529 plans — what happens if the grandchild gets a scholarship, skips college, or the account simply has money left over — has a newer answer. Since 2024, under SECURE 2.0, unused funds in a 529 account that has been open at least 15 years can be rolled over tax-free into the beneficiary's own Roth IRA, up to a $35,000 lifetime cap, TIAA explains.
The rollover is still capped by the beneficiary's annual Roth contribution limit each year, and the beneficiary needs earned income to qualify. For a grandparent weighing whether to open an account now, this removes much of the downside of overfunding it. Money that goes unused for tuition doesn't have to sit idle or trigger penalties — it can become a head start on the grandchild's retirement savings instead, as long as the account has been open long enough to qualify.
Frequently Asked Questions
Does a grandparent-owned 529 plan affect financial aid at every college?
No. It's excluded from FAFSA income and asset reporting starting with the 2024-25 cycle, but over 200 private colleges using the CSS Profile can still count it, per Grown and Flown.
Can a grandparent contribute to a 529 plan the parents already opened and still get a state tax deduction?
It depends on the state. Massachusetts limits the deduction to the account owner, so a contributing grandparent gets no deduction there unless they open their own account, according to SavingForCollege.
What if the grandchild doesn't use all the money for college?
Since 2024, up to $35,000 of unused funds in an account open 15+ years can roll over tax-free into the beneficiary's Roth IRA, per TIAA.
