Nonprofit organizations are subject to a complex set of regulations and law that reflect the diverse organizations that are covered under these rules: charitable organizations, social welfare organizations, memberships organizations, advocacy groups, and many more. These organizations face a special set of rules governing everything from how they charter their organization, to their methods of measuring unrelated business income, and how they lobby (and if, in fact, they should continue to be allowed to lobby). Nonprofit lawyers, accountants, and directors need an easy-to-use reference work in understandable language to help them comprehend the issues and make informed decisions.
