The Internal Revenue Service (IRS) has observed:
Payments an exempt organization receives from donors are nontaxable contributions where there is no expectation that the organization will provide a substantial return benefit. Mere recognition of a . . . contributor as a benefactor normally is incidental to the contribution and not of sufficient value to the contributor to [preclude a charitable contribution deduction]. Examples of mere recognition [that do not nullify a charitable contribution deduction] are naming a . . . building after a benefactor” (IRS News Release IR-92-4).
