Tenn. Code Ann. § 67-3-502: Payment by bonded importer

Except as otherwise provided in this part, the taxes and fees imposed by part 2 of this chapter on taxable petroleum products measured by gallons imported from another state shall be paid by the licensed bonded importer who has imported such products. The taxes and fees shall be paid on or before the twentieth day of the month following the month of import, unless such day falls on a weekend or state or banking holiday, in which case the taxes and fees are due the next succeeding business day. However, if the supplier has made a blanket election to precollect tax under § 67-3-503 , the supplier is jointly and severally liable with the bonded importer for the taxes and fees, and shall remit to the department on behalf of the bonded importer under the same terms as a supplier payment under § 67-3-504 .
