The IRS website concerning non-profits and taxing information is also very helpful.  Unless you run a non-profit, it is unlikely that you know a lot about the tax regulations and benefits.  This guide by the IRS is both official and helpful when thinking about the business side of non-profits and the motivation or downfalls that taxes place on charitable organizations.  When writing a story about charities it is important to be skeptical and to look into the social and economic sides of all of the company's actions.
