The Wikipedia project is currently trying to raise some money to assist project.
US charitable contributions by residents of Canada tax-deductibility of donations thereto by citizens of countries other than the USA -
In case you do not know about this project, you can find it at
www.wikipedia.org
and for the most part I have stopped using search engines because in nearly all cases
I find the information I am looking for in Wikipedia.
Anyway, the matter at hand concerns the following page:
http://wikimediafoundation.org/wiki/Deductibility_of_donations
which contains, in part, the following citation:
Other countries
Donations from individuals who are not U.S. residents or nationals may or may not be tax-deductible — questions about such donations should be directed to a tax professional. Donors living outside the United States should determine whether there is a tax treaty with the United States and their country or other law that would allow them to deduct a donation to Wikimedia from their income. Currently there are tax treaty provisions for deductibility in some cases for Canadian, Mexican and Israeli taxpayers. Again, ask a tax professional for specifics.
I invite comment on this, assuming that the Wikimedia Foundation has a valid 501(c)3 registration in the USA.
