The University of Washington is a governmental tax exempt entity under Internal Revenue Code section 115. The University's activities are generally free from federal tax unless they are unrelated to the mission of the UW. See Unrelated Business Income

The UW is not a 501(c)3, although for tax purposes it is quite similar. On various occasions, grantors, donors and others request proof of our tax exempt status. The most recent correspondence with the IRS along with a cover letter may be viewed here. A letter with respect to our Canadian donors is also available here.
