Mississippi Code Title 27. Taxation and Finance § 27-51-103

(3)(a) Except as otherwise provided in paragraph (b) of this subsection, from and after July 1, 1995, the amount of the credit that a taxpayer shall be allowed against motor vehicle ad valorem taxes due under Chapter 51, Title 27, Mississippi Code of 1972, shall be determined by the State Tax Commission for each fiscal year. The amount of the credit shall be promulgated by the commission on or before May 1 prior to each state fiscal year beginning with the state fiscal year beginning on July 1, 1995. In developing the credit, the commission shall establish credit amounts that provide for an equal percentage of dollar credit amounts for private carriers of passengers and light carriers of property in proportion to their assessed value, based on the projected amount of funds in the Motor Vehicle Ad Valorem Tax Reduction Fund that will be available for distribution in such state fiscal year. The commission may calculate the credit in such a manner so as to have surplus funds available in the Motor Vehicle Ad Valorem Tax Reduction Fund for cash-flow needs and monthly shortfalls that might be incurred as a result of unexpected revenue fluctuations; however, in the calculation of the credit in order to make such surplus funds available, the commission shall attempt to create a balance in the Motor Vehicle Ad Valorem Tax Reduction Fund that does not exceed, at the end of any state fiscal year, five percent (5%) of the projected amount of funds that will be available in the Motor Vehicle Ad Valorem Tax Reduction Fund for distribution during such state fiscal year.

(b) From and after July 1, 2009, through June 30, 2010, a taxpayer shall be allowed as a credit towards the tax liability imposed by Chapter 51, Title 27, Mississippi Code of 1972, on the amount of ad valorem taxes due during the taxable year on any private carrier of passengers and light carrier of property owned by him, an amount equal to four and twenty-five one-hundredths percent (4.25%) of the assessed value of the motor vehicle.
