The receipts of an auctioneer selling property, on a commission or a fee basis, are subject to the gross receipts tax to the extent that the deduction provided by Section 7-9-66 NMSA 1978 does not apply. The receipts of a person selling property through an auctioneer who sells property on a commission or fee basis are subject to the gross receipts tax. However, the person's receipts from such a sale are exempted from the gross receipts tax if the sale is isolated or occasional and the other is neither regularly engaged nor holding out as engaged in the business of selling or leasing the same or similar property.
