(a) A marketplace facilitator shall be considered the retailer of each sale such facilitator facilitates on its forum for a marketplace seller. Each marketplace facilitator shall (1) be required to collect and remit for each such sale any tax imposed under chapter 64H and 64I of the general laws, (2) be responsible for all obligations imposed under chapters 64H and 64I of the general laws as if such marketplace facilitator was the retailer of such sale, and (3) keep such records and information as may be required by the Commissioner of Revenue to ensure proper collection and remittance of said tax.

(b) Any marketplace seller who is a retailer with a valid registration issued under section 7 of this chapter shall not be required to collect the tax imposed under chapters 64H and 64I of the general laws for a particular sale and shall not include the receipts from such sale in its taxable receipts for purposes of its return, if: (1) The marketplace seller can show that such sale was facilitated by a marketplace facilitator (A) with whom the marketplace seller has a contract that explicitly provides that the marketplace facilitator will collect and remit sales tax on all taxable sales such facilitator facilitates for such seller, or (B) from whom such seller requested and received in good faith a properly completed certificate of collection certifying that such facilitator is registered to collect sales tax and will collect sales tax on all taxable sales by such seller and facilitated by such facilitator; and (2) any failure of such facilitator to collect the proper amount of tax for such sale was not the result of such seller providing such facilitator with incorrect information. The commissioner of revenue shall administer the provisions of this subsection.

(c) Any purchaser of tangible personal property or taxable services who overpaid sales or use tax to a marketplace facilitator may submit a claim for refund with the commissioner of revenue in such form and manner as the commissioner prescribes.
