The Nogales, AZ sales tax rate is 8.6% on most retail purchases. Arizona calls it a Transaction Privilege Tax rather than a sales tax, and technically charges the seller, but almost every business passes it through on the receipt. The 8.6% total stacks three layers: 5.6% to the state, 1% to Santa Cruz County, and 2% to the City of Nogales. A few categories — hotels most notably — run considerably higher.
How the 8.6% Breaks Down
Arizona’s base TPT on retail sales is 5% under A.R.S. § 42-5010.1Arizona Legislature. Arizona Code 42-5010 – Rates; Distribution Base An additional 0.6% rides on top, earmarked for education under Proposition 301 and extended through June 30, 2041 by A.R.S. § 42-5010.01.2Arizona Legislature. Arizona Code 42-5010.01 – Transaction Privilege Tax; Additional Rate Increment That is the 5.6% state portion.
Santa Cruz County adds 1%, and the City of Nogales adds 2% for most business classifications. Together, that is the 8.6% that appears on standard retail receipts in town.3Arizona Department of Revenue. Nogales Transaction Privilege Tax Rates
Rates by What You’re Buying
Not every purchase in Nogales is taxed at 8.6%. The city sets different rates for different business activities under Arizona’s Model City Tax Code.4Arizona Department of Revenue. Model City Tax Code Most sit at the standard 2% city rate; lodging is the big exception.
- Retail sales: 2% city, 8.6% combined
- Restaurants and bars: 2% city, 8.6% combined
- Hotels and short-term rentals: 2% base plus a 4% transient lodging tax, so 6% from the city alone5Arizona Office of Tourism. Transient Lodging Tax Rates: Arizona Communities
- Commercial rental and leasing: 2% city
- Residential rental: 2% city
- Prime contracting (construction): 2% city
A hotel night in Nogales ends up at roughly 12.6% once the state and county portions are added in. Worth building into your budget if you are staying near the border.
Professional services — legal advice, accounting, medical care — are generally not subject to TPT. Arizona taxes the sale of tangible goods and specific listed business activities, and most pure service providers fall outside those categories.
Groceries Are Not Fully Exempt
This is where Nogales differs from many Arizona cities. The state exempts food purchased for home consumption from its 5.6% portion.6Arizona Department of Revenue. Tax Exempt Food The City of Nogales, however, taxes groceries at its 2% municipal rate, and the county portion may apply as well.3Arizona Department of Revenue. Nogales Transaction Privilege Tax Rates So your grocery receipt will show a tax line even though shoppers in many other Arizona cities pay nothing.
Shopping Across the Border
Nogales sits on the U.S.-Mexico border, and that shapes a few questions the standard rate chart doesn’t answer.
Retailers in Nogales owe TPT on all sales to customers from Mexico and other foreign countries.3Arizona Department of Revenue. Nogales Transaction Privilege Tax Rates A visitor crossing north to shop pays the same 8.6% embedded in the price as a local resident. There is no tourist or diplomatic exemption on ordinary retail purchases.
Going the other direction, Arizona imposes a use tax on goods bought outside the state and brought back for use here. The use tax rate mirrors the TPT rate, so buying in Mexico to dodge the 8.6% does not actually save you anything if you are following the law. The Department of Revenue does not collect at the port of entry, but the obligation exists.
If You’re the Seller: License, Filing, and Penalties
Any business making taxable sales in Nogales needs a Transaction Privilege Tax license before collecting the first dollar. You apply through the Arizona Department of Revenue on Form JT-1, the Joint Tax Application, which also handles employer withholding and unemployment insurance registration.7Arizona Department of Revenue.

Online Sellers Shipping Into Nogales
Out-of-state sellers with no physical presence in Arizona still owe TPT on sales shipped to Nogales once they cross the state’s economic nexus threshold: $100,000 in gross retail sales into Arizona during the current or previous calendar year.14Arizona Department of Revenue. Out-of-State Sellers Arizona uses the dollar test only; there is no separate transaction-count trigger. Sellers whose Arizona sales all go through a marketplace facilitator like Amazon or Etsy generally do not need their own license, because the facilitator collects and remits on their behalf, and those sales don’t count toward the $100,000 threshold for direct sales.
