Taxes - As enacted, increases, by 15 cents over a 10-year period, and subject to a two-thirds vote of the county legislative body, the maximum mineral severance tax rate that may be levied by a county on all sand, gravel, sandstone, chert, and limestone severed from the ground within its jurisdiction; removes the authorization for Smith County to allocate its mineral severance tax to the county general fund or a fund other than its county road fund. - Amends TCA Title 67, Chapter 7, Part 2.

SB 889 increases Tennessee counties' maximum tax rate for minerals like sand, gravel, and limestone from 15 cents to 30 cents per ton over a 10-year period (phased at 20¢ by 2030 and 30¢ by 2035). Counties must approve any rate increase with a two-thirds vote of their legislative body, and Smith County can no longer use mineral tax revenue for general funds - it must go exclusively to road funding. The bill also requires counties to report annually on how mineral tax revenue is spent for road construction and maintenance. This law, effective upon enactment, directly affects mineral extraction businesses and county budgets across Tennessee.
