Transparency of the Wikimedia Foundation
Wikipedia is operated and supported by the Wikimedia Foundation, a 501(c)(3) tax exempt charitable corporation based in San Francisco, California. In the United States, you may deduct donations from your federally-taxable income.
As a non-profit organization with a core guiding principle of transparency, the Wikimedia Foundation is committed to communicating with our volunteers, donors, and stakeholders in an open, accountable, and timely manner.
Mission Statement of the Wikimedia Foundation
The mission of the Wikimedia Foundation is to empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally.
In collaboration with a network of chapters, the Foundation provides the essential infrastructure and an organizational framework for the support and development of multilingual wiki projects and other endeavors which serve this mission. The Foundation will make and keep useful information from its projects available on the Internet free of charge, in perpetuity.
Beginning in the fiscal year 2007-2008 (July 1, 2007 to June 30, 2008), the Wikimedia Foundation publishes an Annual Report about its goals, accomplishments, and objectives. View past Annual Reports.
We also publish detailed financial reports, such as audited financial statements and our annual plan for each fiscal year.
Since 2014 we have also published Transparency reports, about requests from governments, individuals, and organizations to disclose information about our users or to delete or alter content on our projects
Some local chapters publish their own reports; please view the respective chapter webpages for more information.
