Arizona — nexus note

Economic nexus in Arizona triggers at $100,000 in gross sales delivered into Arizona in the current or prior calendar year. No transaction count threshold.

New Mexico — nexus note

New Mexico gross receipts tax nexus and economic nexus threshold: New Mexico levies a gross receipts tax (GRT) rather than a conventional sales tax. Beginning July 1, 2019, a person lacking physical presence in New Mexico — including a marketplace provider — has economic nexus if, in the previous calendar year, it had at least $100,000 in total taxable gross receipts from sales, leases, and licenses of tangible personal property, sales of licenses, and sales of services and licenses for use of real property sourced to New Mexico (HB 6, 2019). New Mexico uses a sales-only threshold — no transaction-count test. Marketplace providers with at least $100,000 of New Mexico gross revenue collect and remit GRT on sales they make or facilitate. New Mexico uses destination-based sourcing for most GRT, with a statewide rate around 4.875% plus local increments that vary by location.

Frequently asked questions

Which state has the lower sales tax nexus threshold, Arizona or New Mexico?
Both Arizona and New Mexico publish the same economic nexus dollar threshold of $100,000, so a remote seller would reach each state's published threshold at the same level of in-state sales. These are the thresholds published by each state's tax authority as of 2026-06-14; confirm against the official source before registering.
Do both Arizona and New Mexico have marketplace facilitator laws?
Yes. Both Arizona and New Mexico have marketplace facilitator laws, so marketplaces such as Amazon, Etsy, and eBay collect and remit sales tax on the sales they facilitate in both states. Direct-to-consumer sales you make outside a marketplace remain your own responsibility once you cross each state's threshold. Verified 2026-06-14.
Which has the lower sales tax rate, Arizona or New Mexico?
New Mexico has the lower combined state and local sales tax rate at 7.66%, compared with 8.52% in Arizona. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-06-14.
Do I need to register for sales tax in both Arizona and New Mexico?
It depends on where you cross each state's economic nexus threshold (or have physical presence there). Arizona's published threshold is $100,000, and New Mexico's is $100,000. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither. Run the nexus calculator with your actual sales and confirm with each state's official source. Thresholds as of 2026-06-14.
When did economic nexus take effect in Arizona and New Mexico?
Arizona's economic nexus rule took effect on 2021-01-01, and New Mexico's took effect on 2019-07-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
