529 plan distributions used to pay for nonqualified expenses are subject to income tax and a 10% penalty on the earnings portion of the withdrawal. This includes 529 distributions for airfare and other travel costs, college application or testing fees, health insurance, or room and board costs beyond the college’s cost of attendance (COA) allowance.
If the student’s parent qualifies for the AOTC or LLTC, they must adjust their total qualified higher education expenses to avoid double-dipping. To determine the amount of a qualified 529 plan distribution, subtract any amount used to generate the federal education tax credit from the total qualified expenses.

Suppose the beneficiary receives a tax-free scholarship, fellowship grant, Veteran’s educational assistance, employer-provided assistance, or other tax-free educational assistance. In that case, the payment amount must also be subtracted from the total qualified expenses.
For example, parents who claim the AOTC and spend $10,000 on qualified higher education expenses in a given tax year may withdraw $6,000 from a 529 plan without tax consequences:
$10,000 – $4,000 (used to generate the AOTC) = $6,000 Adjusted Qualified Education Expenses (AQEE)
If the student receives a $2,000 tax-free scholarship, the AQEE for the student in this example is reduced further to $4,000.
When the total 529 plan distribution exceeds the AQEE, the excess amount will be subject to income tax on the earnings portion of the withdrawal. However, the 10% penalty is waived when the nonqualified distribution occurs due to the tax credit adjustment up to the amount of the qualified expenses that justified the tax credit.
Similar exceptions to the 10% tax penalty apply when the beneficiary receives a tax-free scholarship, veterans’ educational assistance, employer-paid educational assistance, and other tax-free educational assistance (other than gifts or inheritances). As with the AOTC and LLTC, the tax penalty is waived only to the extent of the qualified expenses that justified the tax-free educational assistance. There are also exceptions when the beneficiary dies, is disabled, or attends a U.S. military academy.
Reporting
The earnings portion of a taxable 529 plan distribution must be reported on the beneficiary’s or the 529 plan account owner’s tax returns. To calculate the taxable portion of the 529 plan distribution:
Divide the AQEE by the total 529 plan distribution (Form 1099-Q, Box 1)
Multiply the answer by the earnings portion of the total distribution (Form 1099-Q, Box 2).
Subtract this amount from the total distributed earnings.
The result must be reported as income on the beneficiary’s or the account owner’s federal income tax return, Schedule 1 Form 1040, line 8. If the distribution is subject to the 10% penalty tax, the additional tax must be reported on Schedule 2 (Form 1040), line 6.
