Tennessee Code Title 67. Taxes and Licenses § 67-3-1110

(a) A dealer, on or before the twenty-fifth day of the month following the end of each calendar quarter, shall file a report and remit the tax due. A dealer who has made no taxable deliveries during the reporting period shall file a report.

(b) A user operating a vehicle used for commercial purposes shall be required to submit a report on or before July 25 of each year, for the previous permitted year and shall remit the tax due. The report must state the ending odometer reading, the number of miles traveled in Tennessee, the number of miles traveled outside Tennessee, and other information required by the commissioner. In the absence of an ending odometer reading, the previous year's mileage shall be presumed to be forty thousand (40,000) miles. A report shall be filed even if no tax is due. Failure to file this report shall result in the tax being assessed based upon the presumption that the vehicle traveled forty thousand (40,000) miles.
