As the Wikimedia Foundation was formed on June 20, 2003, it is now possible for money to be sent to the accounts of Wikimedia. Please note that Wikimedia has not yet received an official determination of its 501(c)(3) tax exempt status under United States federal law, so these donations may be considered taxable income for Wikimedia and may not be deductible from the donor's income under the tax rules. Rest assured that they will be used for Wikimedia projects, including Wikipedia.

Legal status
Created under Florida law, the official corporate address for the Wikimedia Foundation Inc. is in St. Petersburg, Florida, see above address. Any donations (money, stuff, copyright assignments) can certainly be sent to the main address. Please note donations may not be tax deductible for U.S. residents and nationals; please direct any questions in this regard to your tax professional. For those outside the United States please contact local tax authorities to determine if there is any tax treaty that may allow you to deduct your donations to Wikimedia from your income.

Even though Wikimedia is still applying for official tax exempt status it has registered with the Florida Division of Consumer Services, a division of the Florida Department of Agriculture and Consumer Services and may lawfully solicit donations in Florida. Others outside Florida are free to make donations. If you are outside Florida and view this web page do not consider it a solicitation for a donation.

Therefore, anyone who wishes to make a donation, no matter their current residence or the laws of their country, can certainly do so. Wikimedia is a Florida not-for-profit corporation whose purpose is to establish and maintiain free wiki-based projects for world-wide distribution. While Wikimedia may not have a US federal tax-exempt status determination yet, under US Internal Revenue Code provisions if Wikimedia's first year's income is projected to be under $5,000, it has an automatic exemption.
