529 plans aren't new, but three things about them have changed recently enough that a lot of circulating advice about them is now outdated -- especially around grandparents, and around what happens if the money isn't all used.

What a 529 plan actually is

A 529 is a state-sponsored, tax-advantaged education savings account: contributions grow tax-free, and withdrawals for qualified expenses come out tax-free too. There's no federal deduction for contributing, but most states with an income tax offer a state-level deduction or credit for contributions. The account owner controls the funds and can change the named beneficiary to another qualifying family member without penalty -- a real piece of flexibility if plans change.

What counts as a "qualified expense" just got a lot bigger

The traditional list -- tuition, fees, books, supplies, equipment, and room and board at eligible institutions (if enrolled at least half-time) -- is no longer the whole picture. For K-12 education, the annual limit was $10,000, but it's rising to $20,000 a year starting January 1, 2026, and as of July 4, 2025, the range of qualifying K-12 expenses expanded substantially to include curriculum materials, tutoring, AP/SAT/ACT exam fees, dual enrollment costs, and educational therapies -- not just tuition. Also new as of July 4, 2025: postsecondary credentialing expenses are now qualified, covering tuition, exam fees, books, supplies, and equipment for programs leading to professional licenses, certifications, and technical credentials, plus continuing education required to maintain an existing one -- meaningfully expanding what a 529 can pay for beyond a traditional four-year degree. And up to $10,000 lifetime per beneficiary (with a separate $10,000 allowance for each of that beneficiary's siblings) can go toward paying down existing student loans.

The newer, less-known option: rolling unused funds into a Roth IRA

Since January 1, 2024, unused 529 funds can be rolled directly into a Roth IRA for the same beneficiary -- a real answer to the long-standing "what if they don't end up needing it all" hesitation that's kept some families from funding a 529 aggressively. The conditions are real, not a blank check: a $35,000 lifetime cap; the 529 account must have been open for at least 15 years; the specific funds being rolled over must have sat in the account for at least 5 years; the rollover counts against that year's ordinary Roth IRA contribution limit ($7,500 for 2026); the beneficiary needs earned income at least equal to the amount rolled over that year; and it has to be a direct trustee-to-trustee transfer, not a withdrawal you take and redeposit yourself.

What actually changed for grandparents -- outdated advice is still circulating

This is the change most worth knowing if you've heard older advice about 529 strategy. Under the old FAFSA rules, a distribution from a grandparent-owned (or any non-parent-owned) 529 counted as untaxed student income, which could cut a student's aid eligibility by as much as 50% of the distribution amount -- a $10,000 withdrawal from Grandma's account could cost $5,000 in aid. Under the new rules, in effect since the 2024-25 FAFSA cycle (part of the FAFSA Simplification Act redesign), grandparent-owned 529 distributions no longer count as student income at all, and the account itself isn't reported as a parent or student asset either. The old workaround -- avoid grandparent ownership, or wait until the student's final year to tap it -- is no longer necessary. If you're still hearing that advice, it's outdated.

How parent-owned 529s are actually treated (still relevant, still favorable)

A parent-owned (or dependent-student-owned) 529 counts as a parent asset on the FAFSA, assessed at up to 5.64% in the Student Aid Index calculation -- meaningfully lighter than the roughly 20% rate applied to assets held directly in a student's own name outside a 529. A $10,000 balance might reduce aid eligibility by around $564, not $2,000. And regardless of who owns the account, qualified withdrawals are never counted as student income on the FAFSA, as long as the funds go toward qualified education expenses.

Contribution limits -- no small federal cap, but gift tax rules still apply

There's no federal 529 contribution limit as such, but contributions above the annual gift tax exclusion -- $19,000 per donor per recipient for 2026, or $38,000 for a married couple gift-splitting -- start counting against the donor's lifetime gift and estate tax exemption. "Superfunding" lets a donor contribute up to five years' worth of that exclusion at once ($95,000 individually, $190,000 for a couple, for 2026) and elect on IRS Form 709 to spread it evenly across five years for gift-tax purposes -- but doing that means no additional gifts to the same beneficiary during that five-year window without triggering gift-tax consequences. Separately, each state sets its own lifetime aggregate account limit (a balance ceiling above which no further contributions are accepted, though the account can keep growing) -- these vary widely by state, so check the specific plan's limit rather than assuming a figure.

State tax benefits are genuinely inconsistent -- check your own state

More than 30 states offer a state income tax deduction or credit for 529 contributions, but the rules vary in an important way: most require using that specific state's own plan to get the benefit, while nine states -- Arizona, Arkansas, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, and Pennsylvania -- offer "tax parity," allowing the deduction even for contributions to an out-of-state plan. A number of other states, including California, Texas, and Florida, offer no state tax incentive at all, whether because they have no state income tax or simply don't provide a 529-specific benefit. Check your own state's actual rules directly rather than assuming a deduction exists.

What this means for you

  • If you've been avoiding grandparent-owned 529 accounts specifically because of old FAFSA rules, that workaround is no longer necessary -- the rule that used to penalize it is gone as of the 2024-25 cycle.
  • Check your specific state's tax treatment before assuming a deduction exists, and check whether your state is one of the nine offering tax parity before assuming you have to use your own state's plan to get a benefit.
  • Don't let "what if they don't use it all" stop you from funding a 529. The Roth IRA rollover option (up to $35,000, with real conditions) is a genuine release valve that didn't exist before 2024.
  • If you're superfunding to front-load contributions, remember the tradeoff: no additional gifts to that same beneficiary for five years without gift-tax consequences.
