529 Qualified Expenses: What Counts and What Triggers Penalties
Qualified 529 expenses include college tuition and fees, required books and supplies, computers and internet access, special needs equipment, and room and board for students enrolled at least half-time. Beyond college, up to $20,000 per year per beneficiary covers K-12 tuition and expanded K-12 expenses, up to $10,000 lifetime per borrower covers student loan repayment, and registered apprenticeship costs qualify. Spend the money on anything else and the earnings portion faces income tax plus a 10% federal penalty.
The tax-free treatment is the entire point of a 529, and it only applies when the money is spent on qualified education expenses. This guide lists what counts, what does not, and how the penalty works when you get it wrong. It is educational only, not tax advice.
College expenses that qualify
For higher education, the IRS defines qualified expenses broadly as costs required for enrollment or attendance at an eligible institution. An eligible institution is any accredited postsecondary school that participates in federal student aid programs, which covers nearly all public and private colleges, universities, community colleges, and vocational schools.
Tuition and mandatory fees are the core qualified expense, with no annual or lifetime dollar cap. Required books, supplies, and equipment qualify when they are tied to a course: the textbook on the syllabus counts, a decorative notebook does not. Computers, software, related equipment, and internet access qualify for college students. Special needs equipment and services qualify. Room and board qualify when the student is enrolled at least half-time; off-campus housing counts too, but the tax-free amount generally cannot exceed the school's cost-of-attendance allowance for room and board.
K-12 expenses: up to $20,000 per year
Tax-free 529 withdrawals for K-12 are capped at $20,000 per year per beneficiary, aggregated across all 529 accounts for that beneficiary. The One Big Beautiful Bill Act raised the cap from $10,000 and broadened the eligible expenses for distributions after July 4, 2025. Beyond tuition, eligible K-12 expenses now include curriculum materials, tutoring, online learning subscriptions, educational therapies for students with disabilities, standardized test fees, and dual-enrollment tuition. Note the K-12 benefit covers tuition plus these expanded categories, not books and supplies the way the college benefit does in every case, so check the current IRS guidance for the expense you have in mind.
Student loans: up to $10,000 lifetime per borrower
The SECURE Act of 2019 made up to $10,000 of 529 funds per borrower a qualified use for student loan principal and interest. The cap is per borrower, not per account, so a 529 can pay $10,000 toward the beneficiary's loans and $10,000 toward a sibling's loans. This is a useful release valve for families whose children graduate with modest debt and a surplus in the 529.
Apprenticeships and credentialing
Costs of registered apprenticeship programs qualify, which matters for families whose children choose skilled trades over a four-year degree. For distributions after July 4, 2025, credentialing, licensing, and continuing education programs also qualify, including exam fees, tuition, required books, and equipment. The 529 is no longer a college-only vehicle.
Coordinating with education tax credits
One coordination rule trips up many families: you cannot use the same expenses for both a tax-free 529 withdrawal and a federal education tax credit. If you claim the American Opportunity Tax Credit on $4,000 of tuition, those $4,000 are no longer qualified expenses for 529 purposes that year. The practical move is to pay at least $4,000 of tuition from non-529 money to capture the full credit, then use 529 funds for the remaining qualified costs. If you overlap by mistake, the 10% penalty is waived on the overlapping amount, though income tax on the earnings still applies. Plan withdrawals and credit claims together each tax year, not separately.
What does not qualify
Transportation costs (gas, airfare, car purchases), health insurance unless required by the school as a condition of enrollment, extracurricular and club fees, college application fees, and anything already used to generate the American Opportunity or Lifetime Learning tax credit are not qualified. Using 529 money for these triggers tax and the penalty on the earnings portion. Keep receipts and match withdrawals to qualified expenses in the same tax year.
How the 10% penalty works
When a withdrawal exceeds qualified expenses, the IRS prorates the earnings: the taxable earnings equal total earnings times the ratio of non-qualified expenses to the total distribution. Only that slice faces income tax plus the 10% federal penalty. Your original contributions always come out tax- and penalty-free because they were made with after-tax dollars. In practice, the penalty often amounts to just 1 to 3% of the total distribution, roughly the cost of having invested in a taxable account instead.
The penalty is waived in specific situations, though income tax on earnings still applies: the beneficiary dies or becomes disabled, the beneficiary receives a tax-free scholarship (up to the scholarship amount), the beneficiary attends a U.S. military academy, or the withdrawal offsets expenses used to claim the American Opportunity or Lifetime Learning credit. If your child earns a scholarship, you can withdraw an equal amount penalty-free and redirect it wherever the family needs it.
