In the event that any part of the moneys in the Transportation Fund shall, at any time, be applied to a purpose or purposes other than one set forth in this act, every taxpayer who shall have been subject to the tax imposed by this act and who shall have paid the same, shall thereupon be entitled to a refund, or to a credit against taxes subsequently accruing, equal to his pro rata share of the amount so applied, disregarding any amounts less than $1.00. Upon application made within 1 year after it shall be determined that any such moneys have been so applied, in such form and by such procedure as may be provided by regulation, the division shall determine the pro rata share of each taxpayer according to the following formula:
(a) multiply the total amount of taxes paid by the taxpayer for all taxable years from the enactment hereof to July 1 of the year in which the right to refund arises under this section, by the dollar amount of the moneys determined to have been applied to a purpose other than one set forth in this act; then(b) divide the product by the total amount paid by all taxpayers during the same period; then(c) from the quotient strike off any amount less than $1.00 to obtain the sum to be refunded or credited. If the amount so applied to another purpose shall have been determined by a court of competent jurisdiction, the amount so determined shall be used in the computation, otherwise, the division shall make determination of the amount.L.1961, c.32, p.136, s.22, eff. 5/29/1961.
