Although all qualified nonprofit corporations are eligible for exemption from federal income taxes, only those qualified under Section 501(c)3 of the Internal Revenue Code, which are organized for religious, charitable, educational, scientific or literary purposes, enjoy the distinction of giving their donors a tax deduction for contributions to them.  Organizations that receive the 501(c)3 determination from the IRS are commonly referred to as "charities."  There are currently 734,000 charities in the United States, up from 422,000 in 1987.
