IRS oversight of charitable organisations helps to ensure they abide by the purposes that justify their tax exemption and protects the sector from potential abuses and loss of confidence by the donor community. In recent years, reductions in IRS's budget have raised concerns about the adequacy of IRS oversight. This book describes the charitable organisation sector; describes IRS oversight activities; determines how IRS assesses its oversight efforts; and determines how IRS collaborates with state charity regulators and U.S. Attorneys to identify and prosecute organisations suspected of engaging in fraudulent (or other criminal) activity. This book also provides an overview of recent changes affecting tax-exempt and charitable organisations, while also discussing issues that may be of legislative interest in the future.
