Section 4 of the IRS Data Book presents information on collections, penalties, and criminal prosecutions resulting from individuals’ or entities’ failure to comply with the tax code. Failure to comply with filing, reporting, and payment requirements may result in civil penalties or, in some cases, criminal investigation, which may in turn lead to prosecution, fines, and imprisonment. IRS’s Collection function collects Federal taxes that have been reported or assessed but not paid and secures tax returns that have not been filed. IRS’s Criminal Investigation function conducts investigations of alleged criminal violations of the tax code and related financial statutes.
