HB 2510 extends deadlines for counties bordering distressed rural counties to retain sales tax from commercial development projects. Specifically, it pushes back the application deadline from December 31, 2026, to December 31, 2040, and delays the commissioner's approval deadline from June 30, 2031, to June 30, 2041. The bill amends Tennessee Code Annotated, Title 67, Chapter 6, affecting local governments seeking to maintain tax revenue from designated commercial districts. These changes provide additional time for eligible counties to secure tax retention under existing law.
