- Nonqualified 529 withdrawals can trigger tax on earnings plus a 10% federal penalty.
- Families cannot use the same tuition dollars for both 529 benefits and education credits.
- Beginning in tax year 2026, K-12 withdrawals reach $20,000 per beneficiary annually.
A 529 plan can create a tax bill when a withdrawal falls outside the account’s qualified-use rules. The earnings portion may face ordinary income tax and a 10% federal penalty.
The account’s original contributions generally come out tax-free. Savers made those contributions with after-tax dollars, so the tax exposure generally applies to the investment growth connected to a nonqualified distribution.
Families can also run into trouble by assigning one tuition payment to two tax benefits. The same expense cannot support both a tax-free 529 distribution and the American Opportunity Tax Credit.

Timing adds another risk. A withdrawal made in a different tax year from the year the expense was paid can make the growth portion taxable and subject to the additional penalty.
The withdrawal must match both the bill and its tax year
A student-related expense is not automatically a qualified expense. The cost must fit the permitted categories, and the withdrawal must correspond to an expense paid in the applicable tax year.
| Expense or situation | Potential tax problem |
|---|---|
| Transportation | Generally treated as a nonqualified cost. |
| Health insurance | Typically does not qualify for tax-free treatment. |
| Most personal living costs | May produce a taxable distribution. |
| Debt repayment | Generally falls outside qualified expenses. |
| Many extracurricular costs | May not qualify under the account rules. |
| Expense paid in a different tax year | Can make the growth portion taxable and subject to the penalty. |
A bill can be closely connected to school and still fail the tax test. The educational setting alone does not make every cost eligible.
A foreign university does not automatically qualify
A 529 withdrawal for a foreign university is tax-free only when the school participates in U.S. federal student aid. Tuition-free foreign schools often do not meet that condition.
That can change the result of a planned tuition payment. The withdrawal may become a taxable distribution if the institution lacks the required participation.
The school’s location does not decide eligibility by itself. Families should confirm the institution’s status before taking money from the account.
Tax year 2026 gives families more ways to use leftover funds
The rules also provide several paths for using money that remains in a 529 plan. Starting in tax year 2026, the annual tax-free K-12 withdrawal cap is $20,000 per beneficiary per year.
Expanded K-12 qualified expenses now cover costs beyond tuition. The broader allowance does not make every school-related purchase eligible.
| Option | Treatment beginning in tax year 2026 |
|---|---|
| K-12 withdrawals | Up to $20,000 per beneficiary per year tax-free. |
| Leftover funds | Potential rollover to a Roth IRA under SECURE 2.0 rules. |
| Unused balance | Generally transferable to another qualifying family member. |
SECURE 2.0 offers a potential route for moving leftover funds into retirement savings through a Roth IRA rollover. A family may also change the beneficiary to another qualifying family member.
A 529 plan is not inherently a tax trap. Nonqualified withdrawals, overlapping tax benefits and poor timing create the exposure, while ordinary college saving remains within the account’s intended use.
For tax year 2026, families deciding how to use K-12 expenses, overseas tuition or leftover balances face different qualification tests. A qualified tax professional or CPA can assess the treatment of a specific withdrawal.
