Your 529 Plan Now Covers Twice as Much K-12 Spending — But Check Your State First

What Actually Changed

If you've got a 529 college savings plan and a kid in K-12 school, two federal rule changes are worth a second look as back-to-school bills start arriving. Both came from the One Big Beautiful Bill Act (OBBBA), signed into law July 4, 2025.

The annual K-12 withdrawal cap doubled. Since 2018, families could withdraw up to $10,000 per student per year from a 529 plan tax-free for K-12 tuition. As of January 1, 2026, that limit is $20,000 per student per year.

The list of qualifying expenses got longer. Previously, K-12 withdrawals were tuition-only. For distributions made on or after July 4–5, 2025, the qualifying list expanded to include:

• Curriculum and curricular materials
• Books and other instructional materials
• Online educational materials
• Tutoring or educational classes outside the home (the tutor generally can't be a relative, and must be a licensed teacher or a subject-matter expert)
• Fees for standardized achievement tests, AP exams, or college entrance exams like the SAT or ACT
• Dual-enrollment fees for college coursework taken while still in high school
• Educational therapies for students with disabilities, provided by a licensed practitioner

That's a meaningfully broader definition than "tuition," and it lines up well with the kinds of costs that show up every August and September: registration fees, test prep, tutoring packages, and required course materials.

The Catch: Federal and State Rules Don't Always Match

Here's the part that's easy to miss. A 529 withdrawal being federally tax-free doesn't automatically make it state tax-free. Each state decides independently whether to conform to federal 529 rules, and plenty haven't fully caught up. As of early 2026, more than a dozen states — including California, New York, Illinois, and Colorado, among others — don't recognize K-12 tuition and expenses as qualified for state income tax purposes, even though the withdrawal is fine at the federal level.

The newly expanded expense categories — tutoring, test fees, curriculum materials — are more recent than the K-12 tuition rule itself, so states may take longer to formally conform to them, even in states that already treat K-12 tuition as qualified. In a non-conforming state, the federal tax treatment still stands, but the earnings portion of the withdrawal could be subject to state income tax, and a previously claimed state deduction could face recapture — the state clawing back a tax break you already used.

Before assuming a withdrawal is fully tax-free, it's worth checking your specific state 529 plan's current guidance — not just the federal rule — especially if you're using the newly expanded categories for the first time this school year.

A Note on Contribution Timing

If you're planning to add money before using it, remember that most states tie any state tax deduction to the calendar year the contribution is made — typically by December 31 — rather than to a special back-to-school deadline. A 529 contribution doesn't get the same extension to the following spring's tax-filing deadline that an IRA contribution does in most states.

For grandparents or other family members looking to contribute larger sums at once, the federal annual gift-tax exclusion for 2026 is $19,000 per recipient (unchanged from 2025). 529 plans also allow "superfunding": electing to spread a lump-sum gift of up to five times that annual exclusion ($95,000 from one person, or $190,000 if a married couple each contributes and elects to split gifts) over five years on a gift tax return, without touching the separate lifetime gift-tax exemption. That's a mechanical tax rule, not a recommendation to make a gift of any particular size — the right amount depends entirely on your own financial picture.

The Takeaway

The federal rules around 529 plans just got more generous for K-12 families, both in dollar amount and in what counts as a qualifying expense. Whether that generosity fully carries through to your state tax return depends on where you live, so the practical first step this back-to-school season is the boring one: pull up your specific state plan's current published guidance before you count on tax-free treatment for a tutoring bill or test-prep fee.
