Amends TCA Title 6 and Title 67, Chapter 6.

Tennessee HB0079 enacts the "Courthouse Square Revitalization Act," allowing municipalities with populations under 30,000 to designate courthouse square revitalization zones and receive sales and use tax revenue for revitalization efforts. The bill affects incorporated towns or cities designated as county seats, excluding larger municipalities. Key provisions include the requirement for municipalities to apply for approval of revitalization zones, the allocation of tax revenue for maintaining and improving courthouse squares, and the removal of the expiration date for allocations under the existing Courthouse Square Revitalization Pilot Project Act of 2005, making it a permanent program.
