The European for-profit subsidiaries (companies owned by OCLC) provide computer library services to libraries similar to OCLC. However, under European law they do not qualify as "charities" and no other nonprofit legal organization type is available. Only "charities" are exempt from taxes in Europe. OCLC is not a "charity" but a library membership organization. Australian offices are taxable as well.
In the United States, OCLC is tax-exempt under rules that state an organization must be organized and operated exclusively for exempt purposes and none of its earnings may be paid to any private shareholder or individual. The exempt purposes set forth in the U.S. IRS Code Section 501(c)(3) are charitable, religious, educational, scientific, literary and other public purpose organizations.
OCLC, Inc. has offices in Canada and Mexico and their operations are exempt from taxes due to OCLC's nonprofit status in the United States. The Beijing office is taxable under Chinese law.
