There is hereby levied and there shall be paid by every person storing, using or otherwise consuming within the city tangible personal property purchased or brought into the city, an excise tax on the storage, use or other consumption within the city of such property at the same total percentage rate, at all times, as provided by section 4-2-3 of this title, of the purchase price of such property. Such tax shall be paid by every person storing, using or otherwise consuming, within the city, tangible personal property purchased or brought into the city. The additional tax levied hereunder shall be paid at the time of importation or storage of the property within the city and shall be assessed to only property purchased outside the state; provided, that the tax levied herein shall not be levied against tangible personal property intended solely for use outside the city, but which is stored in the city pending shipment outside the city, or which is temporarily retained in the city for the purpose of fabrication, repair, testing, alteration, maintenance or other service. Any person liable for payment of the tax authorized herein may deduct from such tax any local or municipal sales tax previously paid on such goods or services; provided, that the amount deducted shall not exceed the amount that would have been due if the taxes imposed by the city had been levied on the sale of such goods or services.
