The Department of Revenue is responsible for the administration of state tax laws established by the legislature and the collection of taxes and fees associated with those laws. Within each tax type, you will find the definition of the tax, tax rates and due dates for returns. The department also assists with the collection of certain local taxes. Information about those taxes is available as well as forms needed. The information contained in all these pages constitutes “published guidance,” as defined in Tenn. Code Ann. § 67-1-108.
