New Mexico Reverse Sales Tax Calculator
New Mexico uses a Gross Receipts Tax (GRT) rather than a traditional sales tax, but functionally it works the same way — the tax is passed through on receipts. The statewide base rate is 5%, and local additions bring the average to 7.71%. Santa Fe runs at 8.4375%, Albuquerque at 7.875%. Groceries are now exempt following a 2023 change to the law.
The calculator defaults to New Mexico's 7.71% average. For Santa Fe use 8.4375%, Albuquerque 7.875%, Las Cruces 8.3125%. Because it's a GRT rather than a pure sales tax, some services and transactions taxable in New Mexico might not be in other states. The calculator handles the math regardless.

What's Taxable in New Mexico
New Mexico's gross receipts tax (GRT) applies broadly, but groceries (unprepared food) are now exempt following a 2023 change to the law. Previously, food was taxable under the GRT. Prescription drugs were already exempt. Prepared food and restaurant meals are still taxable.
Worked Example
Purchase in Santa Fe totaling $136.75 at 8.4375%.
$136.75 ÷ 1.0844 = $126.11 (pre-tax price)
$136.75 − $126.11 = $10.64 (tax amount)
That's $10.64 in sales tax on a $126.11 purchase before tax. The main calculator handles this automatically — enter the total and rate and the breakdown appears instantly.
