Tenn. Code Ann. § 4-17-301

The general assembly finds and declares that property tax incentives, resulting from legal ownership of valuable business or commercial properties by local governments or their agencies under various statutory programs, has served to promote economic development, but confusion and nonuniformity in structuring such incentives have led to uncertainty in determining property tax liability of new investment prospects. It is the intent of this part to provide for state and local review of property tax incentives for economic development. It is not the intent of this part to authorize new property tax incentives beyond those authorized by law on January 1, 1993.
