§ 24-405.   Computation of Volume of Business.
   1.   Every person subject to the payment of the tax hereby imposed who has commenced his business at least 13 full months prior to the beginning of the license year shall compute his annual gross volume of business upon the actual gross amount of business transacted by him during the preceding calendar year.
   2.   Every person subject to the payment of the tax hereby imposed who has commenced or who commences his business less than 13 full months prior to the beginning of the license year, shall compute his annual gross volume of business for such license year by multiplying by twelve the monthly average of the actual gross amount of business transacted by him during the months in the preceding calendar year he was engaged in business.
   3.   Every person subject to the payment of the tax hereby imposed who commences his business less than 1 full month prior to the end of the preceding calendar year or prior to the beginning of any license years shall compute his annual gross volume of business for such license year upon the gross volume of business transacted by him during the first month of his engaging in business multiplied by the number of months, or fractions thereof, he engages in business in the present calendar year.
   4.   Every person subject to the payment of the tax hereby imposed who engages in a business temporary, seasonal or itinerant by its nature, shall compute his annual gross volume of business upon the actual gross amount of business transacted by him during the license year.
   5.   The Tax Collector is hereby authorized to accept payment under protest of the amount of mercantile tax claimed by the Township in any case where the taxpayer disputes the validity or amount of the Township's claim for tax. If it is thereafter judicially determined by a court of competent jurisdiction that the Township has been overpaid, the amount of the overpayment shall be refunded to the taxpayer. The provisions of this Section shall be applicable to cases in which the facts are similar to those in a case litigated in a court of competent jurisdiction.
