In making such return, the retailer shall determine the market value of any consideration, other than money, received in connection with the sale of any tangible personal property in the course of the business and shall include such value in the return. Such value shall be subject to review and revision by the director as hereinafter provided.

The retailer shall, at the time of making such return, pay to the director the amount of tax herein imposed, except as otherwise provided in this section. The director may extend the time for making returns and paying the tax required by this act for any period not to exceed 60 days under such rules and regulations as the secretary of revenue may prescribe.
