Tenn. Code § 67-4-2807
Notwithstanding any other law, an assessment against a merchant under this part on which a stamp has not been affixed as required by this part shall be made as provided in this section. The commissioner shall assess the tax, applicable penalty, and interest based on any information brought to the attention of the commissioner, or the commissioner's duly authorized assistants, that a merchant is liable for unpaid tax pursuant to this part. The tax shall be assessed in the same manner as any other tax assessment, except when this part specifies otherwise. The commissioner shall notify the merchant in writing of the amount of the tax, penalty, and interest due. The notice of assessment shall be either mailed to the merchant at the merchant's last known address or served on the merchant in person. If the merchant does not pay the tax, penalty, and interest upon receipt of the notice of assessment, the commissioner shall collect the assessment, including penalty and interest, pursuant to the procedures set forth in chapter 1, parts 14 and 18, of this title. The merchant may seek review of the assessment as provided in chapter 1, part 18, of this title. Section 67-1-1802 is applicable to the tax levied by this part.
