What is the marketplace facilitator law in Wyoming?

Wyoming's marketplace-facilitator statute, W.S. 39-15-502, treats a marketplace facilitator as the vendor for each sale it makes for itself or facilitates for a marketplace seller for delivery into Wyoming, and requires it to collect and remit Wyoming sales tax once it meets Wyoming's economic or physical nexus standard — regardless of whether the marketplace seller independently holds a Wyoming sales-tax permit. A facilitator that fails to collect or remit because of incorrect or insufficient seller information has limited relief capped at 5% of the total tax due from its Wyoming sales, with the seller or purchaser remaining liable for the uncollected amount.[6]
