(1) The department may adopt by rule vendor compensation for sellers collecting and remitting sales and use taxes. The vendor compensation may include a base rate or a percentage of tax revenue collected by the seller, and may vary by type of seller. The department may be guided by the findings of the cost of collection study performed under the agreement, by cost of collection studies performed by the department, and by vendor compensation provided by other states, to determine reasonable vendor compensation for sellers for the costs to collect and remit sales and use taxes. Vendor compensation will be funded solely from state sales and use taxes.
(2) A seller is not entitled to vendor compensation while the seller or its certified service provider receives a monetary allowance under RCW 82.32.715.
