Surprising Expenses That Aren’t Eligible

Not all college-related expenses are eligible, even if they seem necessary. For example, you can’t use 529 funds for transportation expenses like traveling to campus or going home during school breaks.

Here are some other expenses that don’t qualify:

• School-sponsored health insurance
• College entrance and application fees
• Fraternity or sorority fees (you can use 529 funds to pay for meals at a fraternity or sorority, but dues are considered ineligible expenses)
• Fees for activities and clubs
• Other living expenses
