The pre-simplification treatment was punishing, and its retirement is what makes grandparent ownership straightforward again. Under the earlier FAFSA formula, a distribution from a grandparent-owned 529 was reported as untaxed income to the student on the following year's FAFSA, at an assessment rate up to 50 percent. Grandparents who wanted to help without hurting aid usually delayed distributions to the last year of college or beyond, or moved the account to the parent before drawing on it. Under the current formula neither workaround is needed: distributions do not appear on the FAFSA at all.
The current FAFSA treatment is one line; the CSS Profile treatment is not. Colleges that use the College Board's CSS Profile for institutional aid decisions have historically asked more expansive questions about family assets, and many still ask about non-parent 529 accounts. The federal financial-aid rule binds the FAFSA and the federal aid it drives; it does not bind a private college's institutional aid formula. Families whose students are targeting CSS-Profile schools should assume that a grandparent-owned 529 could still affect institutional aid at those schools, and confirm the treatment with each institution.
The estate-planning appeal is genuine, and the mechanics need to be right. A section 529 contribution is completed for gift tax purposes, so the amount is out of the grandparent's estate for federal estate tax purposes if the grandparent survives long enough. But the grandparent retains control: change of beneficiary, choice of investments, timing of distributions, and the option to take money back for a non-qualified reason, subject to tax on earnings and a 10 percent penalty on the earnings portion. That combination of removal from the estate with retention of control is unusual and is one of the reasons grandparent-owned 529s appear in more sophisticated estate plans.
The five-year spread election is the standard companion. A grandparent can superfund the 529 by contributing up to five years of annual gift-tax exclusions in a single year and filing a Form 709 to elect the section 529(c)(2)(B) treatment. That is up to five times $19,000 from a single grandparent, and up to ten times that amount from a married couple electing to split gifts. If the grandparent dies during the five-year period, the portion allocable to the years after the year of death is pulled back into the estate under section 529(c)(4)(C).
The direct-tuition-payment alternative is separate and worth knowing. Internal Revenue Code section 2503(e) treats a grandparent's tuition payment made directly to an eligible educational institution as not a gift at all: unlimited amount, no annual exclusion consumed, no Form 709 filing. But the carve-out is tuition only, so room and board, books, supplies, and fees are ordinary gifts. And the payment does not build a tax-advantaged pool the way a 529 does, so appreciation on money still in a 529 grows tax-deferred and comes out tax-free for qualifying expenses. The two techniques serve different jobs and combine well.
