529 Ownership & Tax Planning: Who Should Own the Account?

"Who should own the 529?" is one of the questions we get asked most, and the honest answer is: it depends. The right owner comes down to three things — financial aid impact, state tax deductions, and plan quality. Let's take them one at a time.

How Ownership Affects Financial Aid

Parent-owned 529s are reported as a parental asset on the FAFSA. Parental assets are assessed at a maximum rate of 5.64% under the Student Aid Index (SAI) formula — meaning at most $564 of aid eligibility is affected for every $10,000 in the account. That's a modest impact, and it's often outweighed by the tax and control advantages of parents owning the account.

Grandparent-owned 529s are not reported as an asset on the FAFSA at all, since only the student's and parents' assets are counted. Under the old FAFSA rules (before 2024–25), this created a trap: even though the account wasn't counted, any distribution from a grandparent-owned 529 was reported as untaxed income to the student — and student income could reduce aid eligibility by as much as 50% of the amount distributed. That's what drove the old advice to hold off using grandparent-owned funds until the last two years of school, timed around FAFSA's prior-prior-year rule.

That trap no longer exists. Under the FAFSA Simplification Act, effective for the 2024–25 academic year forward, distributions from grandparent-owned (or any non-parent-owned) 529 plans are no longer reported as student income on the FAFSA. Timing no longer matters for federal aid purposes — grandparent-owned funds can be used in freshman year without any FAFSA consequence.

The one exception: roughly 200 private colleges use the CSS Profile in addition to (or instead of) the FAFSA for institutional aid, and the CSS Profile still asks about non-parent-owned 529 accounts and distributions.

What is the CSS Profile? It's a separate, more detailed financial aid application run by the College Board (not the federal government), used by a couple hundred mostly private colleges and universities — think Ivy League schools, many other selective private colleges, and some private scholarship programs — to award their own institutional aid dollars, on top of or instead of federal aid. It asks for more detail than the FAFSA does: home equity, retirement account balances, small business value, non-custodial parent finances in divorce situations, and — relevant here — 529 accounts owned by grandparents or other relatives. So a school can require both the FAFSA (for federal aid) and the CSS Profile (for the school's own aid), and a family filing the CSS Profile doesn't get the same protection the FAFSA now offers on grandparent-owned 529s.

If a client's family is targeting CSS Profile schools, the old grandparent-ownership caution and the "wait until later years" strategy can still be relevant — it's worth checking each target school's aid methodology before finalizing an ownership structure. (The College Board publishes a list of participating CSS Profile schools each year, which is worth checking early in the process.)

Who Should Get the State Tax Deduction?

Beyond financial aid, the other major consideration is the state income tax deduction — and this is where it gets state-specific.

Most states that offer a 529 deduction only allow it for contributions to their own state's plan. But nine states offer tax parity, meaning residents can deduct contributions to any state's 529 plan, not just their own:

Arizona, Arkansas, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, and Pennsylvania.

A few nuances within that group:

• Most parity states offer a straight deduction. Indiana, Oregon, Utah, and Vermont instead offer a state income tax credit for contributions (note: these four are not parity states — they only apply to in-state plans).
• Minnesota offers either a deduction or a credit, whichever is more favorable, depending on the taxpayer's adjusted gross income.
• Arkansas allows the parity deduction but caps it lower for out-of-state contributions ($6,000) versus in-state ($10,000 for joint filers).

On the other end, four states currently charge income tax but offer no 529 deduction at all: California, Hawaii, Kentucky, and North Carolina.

If a grandparent lives in a parity state and the parents live in a non-deduction state, it often makes sense for the grandparent to own the account — they can invest in whichever state's plan performs best and still claim their home-state deduction, while the family in the non-deduction state loses nothing by not owning it.

Plan Quality Still Matters

Tax deduction aside, 529 plans vary widely in investment performance and fees. Some state programs are excellent; others are mediocre with higher costs. Savingforcollege.com rates plans nationally and is a good independent reference point. If you live in a parity state, this decision is easy — you can pick the best-performing, lowest-cost plan in the country and still get your deduction.

The Decision Framework 

When helping a family think through ownership, I walk through:

1. Will the parents qualify for need-based aid at all? If household income is high enough that aid isn't realistic, ownership structure is a non-issue from an aid standpoint — optimize purely for tax deduction and plan quality instead.

2. Are you targeting CSS Profile schools? If yes, grandparent ownership (and distribution timing) still deserves the same careful treatment it did under the old FAFSA rules. If no CSS Profile schools are in play, this concern mostly falls away.

3. Who gets the better tax deduction — the parent or the grandparent? Compare home states, especially if one is a parity state and the other offers no deduction at all.

4. Will left over 529 money be given to other family members and/or used for the lifetime $35,000 Roth conversion application?

Example: A California family (no state 529 deduction) with a Pennsylvania-based grandparent (a parity state) is a natural fit for grandparent ownership — the grandparent gets a real deduction, can choose any high-quality plan nationally, and under current FAFSA rules, distributions won't touch the grandchild's federal aid eligibility regardless of when they're used. In addition, the 529 can be gifted to any grandchild if there is money left over in the plan or if that grandchild doesn’t use it.  A parent can do the same thing but would not be as likely to do so as a grandparent would, if the money would go to a niece or nephew. 

As you can see, this isn't a one-size-fits-all decision. It depends on the family's income level, their target schools' aid methodology, and where everyone involved lives and files taxes.
