Can a Grandparent Open a 529 for a Grandchild?

Yes, a grandparent can open a 529 plan for a grandchild. There’s no age, income, or employment requirement on the account owner, and starting with the 2024–2025 academic year, money paid out of a grandparent-owned 529 no longer reduces the grandchild’s federal financial aid. You can put in up to $19,000 per grandchild each year without any gift tax paperwork, or as much as $95,000 in a single year using a special five-year election.

Who Controls the Account

In a grandparent-owned 529, you are the account owner and your grandchild is the beneficiary. You choose the investments, decide when withdrawals happen, and decide who receives the money.¹ The grandchild has no legal claim to the funds at any point. That is the main structural difference between a 529 and, say, a custodial account: the child never takes over.

You can also name a successor owner during enrollment. If you pass away, the successor takes control without the account going through probate. The grandchild’s parent is the common choice, but any adult can serve.

What the Money Can Pay For

A 529 is broader than tuition. Withdrawals are tax-free when used for:

Tuition and fees at any college, university, vocational school, or other postsecondary institution that participates in federal student aid programs.
Room and board for students enrolled at least half-time, capped at the greater of the school’s cost-of-attendance housing allowance or the actual charge for on-campus housing.²
Books and supplies required for enrollment.
Computers, software, and internet access used by the student during enrollment, as long as the equipment is not primarily for entertainment.³
K–12 tuition, up to $10,000 per year, at public, private, or religious elementary and secondary schools.³
Student loan repayment, up to $10,000 in lifetime repayments per beneficiary, and the same amount for each of the beneficiary’s siblings.

Anything outside this list is a non-qualified withdrawal. The earnings portion is subject to income tax plus an additional 10% tax. Transportation, health insurance, and optional activity fees feel educational but do not qualify.

How Much You Can Contribute

Contributions to a 529 are treated as completed gifts for federal tax purposes.⁴ For 2026, the annual gift tax exclusion is $19,000 per recipient.⁵ A married couple can give $38,000 per grandchild per year with no gift tax return and no use of the lifetime exemption.

If you want to front-load the account so investment growth has more time to compound, the five-year election lets you contribute up to $95,000 per grandchild in a single year, or $190,000 as a married couple. You file IRS Form 709 and treat the gift as if it were spread evenly across five calendar years.⁴ Any additional gifts to the same grandchild during those five years count against your lifetime exemption.

Every state also sets a total balance cap that applies across all 529 accounts held for a single beneficiary. The caps run from roughly $235,000 to over $620,000 depending on the state. Once combined balances reach that ceiling, no new contributions are accepted, though the existing balance can keep growing through investment returns.

The Financial Aid Question

This is the piece that changed most recently, and it changed in favor of grandparents. Under the older FAFSA, the balance in a grandparent-owned 529 did not count as a student asset, but any distribution the student received had to be reported as untaxed income. That income could reduce federal aid eligibility by up to 50 cents on the dollar. A $20,000 distribution could cost $10,000 in lost grants or subsidized loans.

The FAFSA Simplification Act removed that reporting requirement. The redesigned FAFSA no longer asks about cash support from anyone other than the student’s parents, and it no longer asks students to report distributions from grandparent-owned 529 accounts. The account balance is also excluded from the asset calculation because the grandparent, not the parent, owns it. For federal aid purposes, distributions from a grandparent-owned 529 now have zero effect.

One Exception: CSS Profile Schools

About 200 private colleges use the CSS Profile, a separate aid application, to hand out their own institutional grants and scholarships. The CSS Profile still asks about 529 accounts owned by non-parents and may factor those balances or distributions into its formula. This is a school-by-school issue that affects only institutional aid, never federal Pell Grants or federal subsidized loans. If your grandchild is applying to a private college that uses the CSS Profile, ask that specific school how it treats grandparent-owned accounts before making a large distribution.

Opening the Account

You’ll need a Social Security number, date of birth, and mailing address for both yourself and your grandchild. Most state plans let you enroll online in under 20 minutes, and you don’t have to live in the state whose plan you choose. A grandparent in Florida can open a plan run by Utah or Nevada if the investment lineup or fees look better. Weigh that against any state income tax deduction your home state offers for using its own plan.

Once the account is open, you’ll link a bank account for contributions. Minimum initial deposits range from as little as $25 to a few hundred dollars depending on the plan, and most plans accept recurring automatic contributions on whatever schedule works for you.

Age-Based or Static Portfolios

Most plans offer two approaches. Age-based portfolios start stock-heavy when the grandchild is young and shift toward bonds as college approaches, so market swings do less damage near tuition time. Static portfolios lock in a fixed allocation (aggressive, moderate, or conservative) that only changes if you change it. Age-based options suit grandparents who don’t want to actively manage the account.

If Plans Change

Life shifts. A 529 has more flexibility than most grandparents expect.

You can change the beneficiary to another qualifying family member of the current beneficiary without tax consequences. Federal law defines “family member” broadly enough to include siblings, parents, first cousins, aunts, uncles, in-laws, and their spouses. A 529 opened for one grandchild can be redirected to another grandchild, or even a great-grandchild.

You can also withdraw the money for yourself. The contribution portion comes back with no penalty because it was made with after-tax dollars, but the earnings portion is subject to income tax and the 10% additional tax.¹ Treat this as a last resort rather than a plan.

If the grandchild wins a scholarship or picks a less expensive school and money is left over, the SECURE 2.0 Act allows a rollover from the 529 into a Roth IRA in the beneficiary’s name. The conditions:

The 529 must have been open at least 15 years for the current beneficiary.
Any funds being rolled over must have been in the account at least five years.
Rollovers in a given year can’t exceed the Roth IRA annual contribution limit, which is $7,500 for 2026.⁶
Total lifetime rollovers per beneficiary are capped at $35,000.
The beneficiary must have earned income in the year of the rollover.

The 15-year clock is a good reason to open the account early, even with a small initial deposit. Starting it at birth gives the most flexibility later.

Two Cautions Before You Fund It

If you ever apply for Medicaid to cover nursing home or long-term care costs, the full balance of any 529 you own counts as your personal asset. You would need to liquidate the account, pay income tax and the 10% penalty on earnings, and spend down the proceeds before qualifying. Transferring ownership to someone else doesn’t fix this, because Medicaid treats the transfer as a gift that triggers a penalty period. If long-term care exposure is on your radar, talk to an elder law attorney, or consider contributing to a parent-owned 529 instead of owning the account yourself.

The five-year election has its own catch for older grandparents. If you die before the five years are up, the portion allocated to the remaining years is pulled back into your gross estate.⁷ Contribute $95,000 and die in year three, and $38,000 comes back into your estate. Investment earnings inside the account stay out regardless. For estates comfortably under the federal exemption ($13,990,000 per person for 2025, adjusted annually), this triggers no actual tax. For larger estates, timing matters and a series of annual contributions may be safer than a single lump sum.

Grandparent-Owned or Contribute to a Parent-Owned Plan?

With the FAFSA change, the federal aid penalty that used to argue against grandparent ownership is gone. You can also skip owning an account entirely and just contribute to one the parent already owns. You still get the money out of your taxable estate, the parent keeps the reins, and there’s only one account to coordinate if several relatives are chipping in.

Owning the account yourself makes the most sense when you want direct control over investments and withdrawal timing, when you’re using the 529 as an estate planning vehicle, or when the parent’s finances make a parent-owned account less practical. And if the grandchild might apply to a CSS Profile school, contributing to a parent-owned 529 sidesteps the institutional aid question, since parent-owned assets are already reported on the FAFSA at the lower parental rate.
