Why the rate here is not the whole story
New Mexico has no sales tax in the strict sense. It levies a gross receipts tax, or GRT, on the seller for the privilege of doing business, and the seller normally passes it on at the register, so it works like a sales tax for a buyer. The state charges 4.875 percent and municipalities add their own on top, but San Miguel County's own levy is not one number either: it is 1.7083 percent in the unincorporated remainder of the county and 1.2083 percent inside a municipality, because part of the county levy applies only outside city limits. The floor of 6.5833 percent is the remainder of the county, outside any municipality. The ceiling of 8.1458 percent is at Las Vegas. Food for home consumption sold by a retail food store is deductible from gross receipts under Section 7-9-92 NMSA 1978, so groceries are generally not taxed at the till, while prepared food and restaurant meals are. Confirm an address on the department's own rate map before charging it.
