Are memberships tax-deductible?

Basic and Ultimate memberships levels are not considered tax-deductible for federal income tax purposes. Memberships at the donor levels (Patron Society, Scholars Society, Explorers Society, Leadership Society, and Visionary Society) are considered partially tax-deductible. The amount of membership dues that is deductible is the amount paid minus the fair market value of benefits.

Please note that prices and fair market values are subject to change. COSI recommends you consult a tax advisor with further tax-related questions.
