The excise tax is imposed on the first sale or use of Diesel motor fuel to occur which is not exempt from tax under this article. Provided, however, if the tax has not been imposed prior thereto, it shall be imposed on the removal of highway Diesel motor fuel from a terminal, other than by pipeline, barge, tanker or other vessel, or the delivery of Diesel motor fuel to a filling station or into the fuel tank connecting with the engine of a motor vehicle for use in the operation thereof whichever event shall be first to occur. The tax shall be computed based upon the number of gallons of Diesel motor fuel sold, removed or used or the number of gallons of Diesel fuel delivered into the fuel tank of a motor vehicle, as the case may be. Nothing in this article shall be construed to require the payment of such excise tax more than once upon the same Diesel motor fuel. Nor shall the collection of such tax be made applicable to the sale or use of Diesel motor fuel under circumstances which preclude the collection of such tax by reason of the United States constitution and of laws of the United States enacted pursuant thereto. Provided, further, no Diesel motor fuel shall be included in the measure of the tax unless it shall have previously come to rest within the meaning of federal decisional law interpreting the United States constitution. All tax for the period for which a return is required to be filed shall be due on the date limited for the filing of the return for such period, regardless of whether a return is filed as required by this article or whether the return which is filed correctly shows the amount of tax due.
