Tennessee Code Title 6. Cities and Towns § 6-22-106

(a) As soon as practicable in each year after the assessment books for the state and county are complete, which shall be after boards of equalization provided for by general laws shall have finished their work, it is the duty of the finance director to prepare or cause to be prepared, from the assessment books of the county and of the comptroller of the treasury, a tax book similar in form to that required by laws of the state to be made out for the county trustee, embracing, however, only such property and persons as are liable for taxes within the city.

(b) Such tax books, when certified to be true, correct and complete by the finance director, shall be the assessment for taxes in the city for all municipal purposes; provided, that there may be an assessment by the finance director at any time, of any property subject to taxation found to have been omitted, and such assessment shall be duly noted and entered on the assessment books of the city. Instead of the assessment made by county and state officials as provided in this section, the city may, by ordinance insofar as not prohibited by general laws, provide for and regulate an assessment to be made by its own assessor of property.
