Although Avaaz.org is a non-profit organization, donations made to Avaaz are not tax deductible. Avaaz is registered in the United States where there are two categories of non-profits. 501(c3)s are charitable organizations that work for the public good. 501(c4)s are also non-profits, however, they are allowed to engage in political campaigning, and for this reason donations are not tax deductible. Avaaz is currently only registered in the US.
