New Mexico Sales Tax: Rates, Rules, and How to Calculate It (2026)
New Mexico doesn't levy a traditional sales tax—it charges a gross receipts tax (GRT) that legally falls on the seller, though it's almost always passed on to the buyer. The statewide GRT rate is 4.875 percent, and local governments add their own, so the combined rate runs from about 5 percent up to 10.875 percent. Sellers into New Mexico need the right local rate for each address just as they would with a sales tax.

How much is sales tax in New Mexico?
New Mexico's state gross receipts rate is 4.875 percent. Every county and municipality layers its own local GRT on top, which is why the combined rate ranges from around 5 percent in the lowest areas to 10.875 percent in places like Shiprock. Across the 450 taxing areas we track in New Mexico, the average combined rate is about 7.32 percent. Because GRT is imposed on the business's receipts, the location that matters is generally where the goods or services are delivered.
The gross-receipts structure changes the mechanics but not the practical need: you still have to resolve the correct combined rate for the delivery address. Local rates vary widely between neighboring jurisdictions, so an address lookup is the reliable way to find the rate that applies rather than estimating from the 4.875 percent state figure.
What's taxed and what's exempt in New Mexico
Food is a notable exemption in New Mexico: sales of groceries at a retail food store are deductible from gross receipts, so unprepared food is effectively exempt. Prepared and restaurant food remains taxable. Clothing is taxable at the combined local rate.
New Mexico's gross receipts tax reaches more than tangible goods—it applies broadly to services and to software as a service, so SaaS and many digital products are taxable here. Prescription medicine is exempt. Because GRT applies to categories that a conventional sales tax often skips, confirm how a specific service or digital product is treated before assuming it's untaxed.
Do you have to collect New Mexico sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, New Mexico requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into New Mexico per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm New Mexico's current threshold before you rely on it.
If you sell into New Mexico from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate New Mexico sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 7.307% means about $7.31 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
