Miss. Code § 27-51-35
Any municipality in the state electing not to adopt the motor vehicle assessment schedule for the assessment and collection of its ad valorem taxes on motor vehicles, provided for by Section 27-51-19, shall order its tax assessor to prepare and file with the municipal board of such municipality an assessment schedule for such purposes, excepting motor vehicles owned by public utilities and railroads, which, under the authority of Section 27-35-301, Mississippi Code of 1972, are assessed by the state tax commission. The said order shall be made of minute record and a certified copy shall be furnished the municipal tax assessor.
In preparing the assessment schedule, the municipal tax assessor shall comply in general with the provisions of Section 27-51-19, excepting that he shall equalize the assessed value of motor vehicle with the assessed value of other property located within his jurisdiction rather than with the assessed value of property throughout the state.
