Upon each sale of tangible personal property or services, the gross receipts from which are taxable under this title, the reim- bursement of tax to be collected by the vendor from the purchaser under the provisions of this title shall be stated and charged separately from the sales price and shown separately on any record thereof at the time the sale is made or evidence of sale issued or employed by the vendor. SEC. 130. It shall be presumed that all receipts from the sale of tangible personal property and services mentioned in this title are subject to tax until the contrary is established, and the burden of proving that a receipt is not taxable hereunder shall be upon the vendor or the purchaser as the case may be. Except as provided in section 128 (c) of this title, unless the vendor shall have taken from the purchaser a certificate signed by and bearing the name and address of the purchaser and the number of his registration certificate to the effect that the property or service was purchased for resale, the receipts from all sales shall be deemed taxable. The certificate herein required shall be in such form as the Assessor shall prescribe and, in case no certificate is furnished or obtained prior to the time the sale is consummated, the tax shall apply to the gross receipts therefrom as if the sale were made at retail. SEC. 131. The tax imposed by this title and interest and penalties thereon shall become, from the time due and payable, a personal debt of the person liable to pay the same to the District. An action may be brought at any time within three years from the time the tax shall be due and payable in the name of the District to recover the amount of any taxes, penalties, and interest due under the provisions of this title, but such actions shall be utterly barred after the expiration of the aforesaid three years.
