Can You Use a 529 Plan for K-12 Tuition? The 2026 Rules

Yes, you can use a 529 plan for K-12 tuition, and the rules got more generous in 2026. What started in 2018 as a narrow allowance for private school tuition has grown into a bigger annual amount covering a wider set of expenses. The catch is that these are federal rules, and your state may not follow them, which can turn a federally tax-free K-12 withdrawal into a taxable event on your state return. Before you tap a 529 for grade school, it is worth understanding the new $20,000 limit, exactly what qualifies, the state tax trap, and whether spending college money on K-12 is a good idea in the first place.

The Short Answer

Federally, a 529 plan can pay for K-12 costs, and the withdrawal is free of federal income tax on the earnings as long as it stays within the annual limit and covers qualified expenses (IRS Publication 970). This is the same account most families open for college; the K-12 use is simply another qualified purpose the money can serve. You do not need a special K-12 account, and you do not lose the option to use the rest for college later.

The two things to get right are the dollar limit and your state's position. The federal limit caps how much of a 529 you can spend on K-12 each year, and your state decides whether it honors the federal treatment or taxes the withdrawal. Miss either and a move that looked tax-free can cost you.

The 2026 Limit: $20,000 a Year

The One Big Beautiful Bill Act, signed on July 4, 2025, doubled the annual K-12 limit. Starting in tax year 2026, you can withdraw up to $20,000 per beneficiary per year for K-12 expenses, up from the previous $10,000 cap (IRS). The limit is per beneficiary, not per account, so if a child has more than one 529 (say one from a parent and one from a grandparent), the $20,000 ceiling applies across all of them combined for that child.

A few details make the limit workable in practice:

• It is annual, not lifetime. The cap resets each year, so a family can use up to $20,000 for each year the child is in K-12.
• It is per beneficiary. Two children in private school can each draw up to $20,000 from their own 529 balances.
• Amounts above the cap are not qualified. Withdraw more than $20,000 for one child's K-12 costs in a year and the excess earnings become taxable, with a 10% penalty on that earnings portion.

Because $20,000 covers a large share of many private school tuitions, the higher limit makes the 529 a more realistic tool for K-12 than the old $10,000 cap did.

What K-12 Expenses Qualify

The 2018 rules limited K-12 use to tuition at a public, private, or religious school. The 2025 law widened the definition of qualified K-12 expenses for distributions taken after July 4, 2025, to include more than tuition (IRS). The expanded list covers a broader set of education costs:

• Tuition at a public, private, or religious elementary or secondary school
• Curriculum and curricular materials, books, and other instructional materials
• Tutoring and educational classes outside the home
• Fees for standardized tests, advanced placement exams, and college admission exams
• Dual-enrollment fees for postsecondary courses
• Educational therapies for students with disabilities

This is a real expansion, since it reaches costs that families of homeschooled and privately schooled children were already paying out of pocket. As with college, keep records showing that each withdrawal matched a qualified expense in the same year, because the burden is on you to document it if asked. This is educational information, not tax advice; the precise list and any later guidance should be confirmed against IRS Publication 970 and your plan.

The State Tax Catch

Here is the part that catches families off guard. The $20,000 limit and the expanded expense list are federal. States write their own 529 tax rules, and not every state has adopted the federal K-12 treatment. In a state that does not conform, a K-12 withdrawal that is perfectly tax-free on your federal return can still be taxed as income on your state return, and some states will also "recapture" any state tax deduction you previously claimed on the contributions.

That creates two distinct risks in a non-conforming state:

• State income tax on the earnings of the K-12 withdrawal, even though it is federally tax-free.
• Recapture of prior state deductions, meaning the state adds back deductions you took in earlier years for putting the money in.

The practical rule: never assume your state follows the federal K-12 rules. Check your own state's 529 program guidance before making a K-12 withdrawal, since the same move can be tax-free in one state and costly in the next (Saving for College). If you contributed specifically to get a state deduction and now plan a K-12 withdrawal, the recapture risk deserves a close look.

Should You Do It?

Just because you can use a 529 for K-12 does not always mean you should. The core trade-off is time. Money spent on grade school is money that stops compounding for college. A dollar withdrawn when a child is eight has lost the ten years of potential tax-free growth it would have had if left until college. For families whose 529 is earmarked for higher education, pulling from it early can shrink the college fund more than the tuition bill suggests.

A few situations where K-12 use can still make sense:

• Your state conforms and offers a deduction. In some states, contributing and then withdrawing for K-12 in the same year can effectively run tuition through the account for a state tax break, with no recapture. This only works where the state allows it.
• You have more than enough for college. If the 529 is already ahead of the college target, using some for K-12 spends a genuine surplus rather than raiding the goal.
• You would pay the tuition anyway. If private school is already in the budget, routing eligible costs through a conforming 529 can add a tax benefit to spending you are committed to.

Work a quick example to see the cost of pulling early. Suppose a 529 holds $30,000 when a child is eight, and the family withdraws $10,000 for private middle school. That $10,000 is gone from the college fund, but so is roughly a decade of potential tax-free growth on it. At a long-run return in the range many age-based portfolios target, the amount left to compound is what builds the college balance, so an early K-12 withdrawal can cost the fund noticeably more than the sticker amount by the time college arrives. The tuition is paid either way; the question is whether it comes from the invested college pot or from current income.

For families still building toward college, the safer default is to leave the 529 invested for the long horizon and pay K-12 costs from current income.

Frequently asked questions

Can you use a 529 plan for K-12 private school tuition?

Yes. Federal rules let a 529 pay K-12 tuition at a public, private, or religious school, with the earnings free of federal income tax up to the annual limit. For 2026, that limit is $20,000 per beneficiary per year. State tax treatment varies, so confirm your state conforms before making a K-12 withdrawal.

How much can a 529 pay for K-12 per year in 2026?

Up to $20,000 per beneficiary per year for tax year 2026, doubled from the previous $10,000 cap by the One Big Beautiful Bill Act. The limit is per child across all of that child's 529 accounts combined, and it resets annually. Withdrawing more than $20,000 for one child's K-12 costs in a year makes the excess earnings taxable with a 10% penalty.

What K-12 expenses qualify for a 529 in 2026?

Beyond tuition, the expanded federal list includes curriculum and instructional materials, books, tutoring and educational classes, fees for standardized and AP exams, dual-enrollment fees, and educational therapies for students with disabilities. Keep documentation matching each withdrawal to a qualified expense, and confirm details against IRS Publication 970.

Will my state tax a 529 withdrawal for K-12?

It might. The $20,000 limit and expanded expenses are federal rules, and not all states conform. In a non-conforming state, a K-12 withdrawal that is federally tax-free can still be taxed on your state return, and some states recapture prior state deductions. Always check your state's 529 rules before a K-12 withdrawal.
