Sales Tax in Arizona: A Complete Guide for Ecommerce Sellers

Arizona levies a Transaction Privilege Tax (TPT) rather than a traditional sales tax, it’s technically a tax on the privilege of doing business in Arizona, assessed on the seller rather than the buyer. For remote sellers, the practical compliance steps are similar to other states. Arizona’s combined rates vary widely by city and county, and shipping is generally not taxable when separately stated, one of the few major states with this rule.

Quick reference

Economic nexus

Arizona uses a sales-only threshold: $100,000 in gross sales into Arizona in the current or prior calendar year. There is no separate transaction count threshold.

Arizona enacted its economic nexus rules effective October 1, 2019.

Physical nexus

Physical presence in Arizona creates nexus without any threshold:

• Warehouse, office, or storage facility in Arizona
• Amazon FBA inventory in Arizona fulfillment centers
• Employees, agents, or independent contractors in Arizona
• Sales representatives in Arizona

Registration

Register through AZTaxes.gov, the Arizona Department of Revenue’s online portal. There is a $12 one-time TPT license fee, unlike most states, Arizona charges a nominal registration fee.

Arizona issues a TPT license. Sellers must list the business classification(s) applicable to their activities, retail is the most common for ecommerce sellers.

Tax rates

State TPT rate (retail): 5.6%

County rates: Arizona counties levy an additional county rate. Maricopa County (Phoenix metro) adds 0.7%; Pima County (Tucson) adds 0.5%.

City rates: Arizona cities levy their own rates, which vary significantly. City rates range from 1.5% to 4%+ depending on the municipality.

Combined rate examples:

• Phoenix: 8.6% combined (5.6% state + 0.7% county + 2.3% city)
• Scottsdale: 8.05% combined
• Tucson: 8.7% combined
• Mesa: 8.3% combined
• Chandler: 7.8% combined

Arizona’s rate structure requires address-level calculation because city boundaries and rates vary significantly across the Phoenix metro area.

What’s taxable

Generally taxable: Electronics, furniture, sporting goods, toys, most tangible personal property.

Generally exempt:

• Prescription medications
• Food for home consumption (groceries — Arizona broadly exempts food for home consumption from TPT)
• Agricultural products and equipment
• Residential rental

Notable Arizona rules:

• Clothing: Taxable in Arizona, no clothing exemption
• Digital products: Arizona taxes specified digital products, including downloaded software and digital audio/audiovisual works
• SaaS: Arizona has guidance indicating that remotely accessed software (SaaS) may be taxable under TPT in certain circumstances, sellers of SaaS into Arizona should confirm taxability for their specific product
• Food: Arizona broadly exempts food for home consumption from state TPT. Prepared food and restaurant meals are taxable at higher rates. Candy and soft drinks are taxable

Shipping taxability

Arizona does not impose TPT on separately stated delivery charges. When delivery charges are listed as a separate line item on the invoice, they are not subject to TPT.

When shipping is included in the sale price (not separately stated), it becomes part of the taxable selling price and is taxable if the goods are taxable.

Practical implication: Always separately state shipping on Arizona invoices to exclude delivery charges from TPT. This preserves the exemption on every shipment.

Marketplace facilitator rules

Arizona enacted marketplace facilitator legislation effective October 1, 2019. Qualifying marketplace facilitators collect and remit Arizona TPT on marketplace-facilitated sales.

Remote sellers with no Arizona physical nexus whose only Arizona sales are through marketplace facilitators may not need to separately register. Sellers with Arizona physical nexus must register regardless.

State-specific notes

TPT is a seller-side tax: Arizona’s Transaction Privilege Tax is structurally a tax on the seller’s privilege of doing business in Arizona, not a tax collected from the buyer. In practice, sellers pass the cost to buyers, making it function like a sales tax. But this distinction means Arizona’s rules, forms, and audit procedures are organized around TPT rather than “sales tax” — terminology in Arizona’s guidance and forms reflects this.

$12 registration fee: Arizona is one of the few states that charges a nominal registration fee. The $12 TPT license fee is a one-time cost and covers all business locations.

Shipping exemption: Arizona’s treatment of separately stated shipping charges as non-taxable is a seller-favorable rule. Ecommerce sellers should configure their checkout to display shipping as a separate line item rather than bundling it into product prices.

City boundary complexity: Arizona’s municipalities are tightly integrated in metro areas, and city boundaries can cross county lines. Phoenix, Mesa, Tempe, Chandler, Gilbert, and Scottsdale all have different rates, sellers with high Arizona volume need rooftop-level address assignment.
