The LibreOffice and Document Foundation websites each have a donation page. I think they should mention if money contributions from US sources qualify as tax deductions. This would be most useful in the English language version of the websites. I am guessing that the following methods would not currently qualify: PayPal donations to donations@documentfoundation.org Donations sent to Freies Office Deutschland e.V. and marked “The Document Foundation” Another method is contributions to Software in the Public Interest (SPI) that are marked for use by The Document Foundation. This seems more likely to qualify, but should be confirmed. The LibreOffice website lists SPI as a channel for contributions. The Document Foundation website does not list SPI, and it should be added there. Here is the US Internal Revenue Service (IRS) search page for organizations eligible to receive tax-deductible charitable contributions: http://www.irs.gov/app/pub-78/ -- Unsubscribe instructions: E-mail to website+help@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/website/ All messages sent to this list will be publicly archived and cannot be deleted
