Your charitable contribution to RRI are tax deductible for federal income tax purposes!
RRI is a tax-exempt public charity under section 501(c)(3) of the Internal Revenue Code, meaning it is not taxed for income by the U.S. government. Moreover, donors to RRI may deduct the value of their contributions from their own income tax calculations, according to published IRS rules. Many state governments have similar tax provisions.
Naturally, the applicable rules are complex and sometimes confusing, so donors should seek the advice of their tax professionals before making a donation.
