Comptroller, State - As enacted, adds to the list of companies for which the comptroller of the treasury may assess for taxation, and for state, county, and municipal purposes, all of the properties within the state owned, and all personal property used or leased, motor bus or truck companies, excluding towing companies, that meet certain criteria. - Amends TCA Title 4; Title 8; Title 9; Title 66 and Title 67.

SB 1673 extends the deadline for property owners or entities to file objections to state property tax assessments. It changes the filing window from 20 to 25 days after the first Monday in September, giving affected parties more time to challenge assessments with the state board of equalization. This procedural change directly impacts individuals and businesses receiving property tax assessments from Tennessee's comptroller of the treasury. The bill amends specific sections of Tennessee law related to state property assessments (TCA Titles 4, 8, 9, 66, and 67).
