As introduced, this bill provides for the comprehensive revision of the distribution of state and local TAVT proceeds. First, during a four-year phase in period, counties (and other local governments) first receive proceeds based upon the 2012 tax year ad valorem collections minus the amount of ad valorem tax collected in the current month. During that phase-in period, the remaining amount is split between the state and local governments on a graduated scale that shifts more money to the local governments. Following the phase in period, all vehicle ad valorem taxes and TAVT proceeds are split 30 percent to the state and 70 percent to local government. During the phase in period, the distribution of local TAVT proceeds among counties, schools, and cities remains the same as at present. Under a proposed substitute to the original bill, beginning in 2022 the county/schools/cities split would be at the average percentages those entities received from 2018 through 2021. More information is available here. 

As passed by the Senate Finance Committee, the above changes to the state/local distribution of TAVT was removed from the bill. As ultimately approved by both the Senate and House, HB 340 only changes the formula for calculation of TAVT on leased vehicles.
