Arizona Sales Tax and Invoicing Rules for 2026

State sales tax rate

Arizona does not technically have a "sales tax" — it levies a Transaction Privilege Tax (TPT) of 5.6% on the privilege of doing business in the state. The distinction matters: TPT is levied on the seller, not the buyer, though it is customarily passed through.

Cities and counties add their own TPT rates, with combined totals ranging from 7.5% to 11.2%. Phoenix has a combined rate around 8.6%. Tucson is approximately 8.7%. Scottsdale sits at about 7.95%.

Arizona uses origin-based sourcing — in-state sellers charge the rate where their business is located. Out-of-state remote sellers use the destination rate.

Nexus rules

Physical nexus applies through offices, employees, inventory, or property in Arizona.

Economic nexus triggers at $100,000 in gross proceeds from Arizona sales in the current or prior calendar year. There is no transaction count threshold.

Arizona combined its state and city TPT administration into a single filing system managed by the Arizona Department of Revenue (ADOR) in 2017, simplifying compliance significantly. Marketplace facilitators must collect and remit on behalf of third-party sellers.

Invoice requirements

Because TPT is technically a tax on the seller's privilege of conducting business, there is no legal requirement that the seller pass the tax to the buyer or show it on the invoice. However, most businesses do pass it through and show it separately.

The ADOR requires sellers to maintain records that support all reported transactions, including:

• Date of transaction
• Seller and buyer information
• Description of goods or services
• Gross receipts and deductions claimed
• Tax calculated

For exempt transactions, retain the applicable exemption certificate (Form 5000 series). Records should be maintained for four years.

Exemptions and special cases

Groceries (food for home consumption) are exempt from state TPT but may be subject to some city TPT in certain municipalities.

Prescription drugs are exempt. Manufacturing machinery and equipment used directly in manufacturing are exempt. Agricultural equipment and inputs are exempt for qualifying farmers. Clothing is fully taxable.

SaaS and digital goods have nuanced treatment — Arizona generally taxes tangible personal property transferred electronically. SaaS is generally treated as a nontaxable service unless it involves the transfer of tangible personal property.

Construction contracting has its own separate TPT classification with distinct rules.

Filing frequency and deadlines

Filing frequency depends on liability:

• Monthly — most businesses
• Quarterly — smaller sellers
• Annually — very small sellers

Monthly returns are due the 20th of the following month. Quarterly returns are due April 20, July 20, October 20, and January 20. Annual returns are due January 20.

Arizona's unified TPT return covers state, county, and city taxes in a single filing — a significant convenience. Electronic filing through AZTaxes.gov is required for most filers.

Penalties for non-compliance

Late filing incurs a penalty of 4.5% per month on unpaid tax (up to 25%). Interest accrues at the rate established by ADOR.

Failure to obtain a TPT license before conducting business is a class 3 misdemeanor. The ADOR conducts audits and participates in multi-state information sharing. Back-assessments apply from the date nexus was established.

FAQ

What is the difference between TPT and regular sales tax?

TPT is levied on the seller for the privilege of doing business, while traditional sales tax is levied on the buyer. In practice, most sellers pass TPT to buyers and itemize it on invoices. The legal distinction matters for exemptions and how deductions are calculated.

Does Arizona's origin-based sourcing mean I always charge my local rate?

For in-state sellers, yes — you charge the combined rate for your business location, regardless of where the buyer is. Out-of-state remote sellers use destination-based sourcing and charge the rate at the buyer's address.

Are food deliveries from restaurants taxable?

Yes. Prepared food and restaurant meals are subject to TPT at the full combined rate. Only unprepared food items sold for home consumption qualify for the food exemption from state TPT.

Step-by-step: register and start collecting in Arizona

1. Confirm nexus — physical presence in AZ (Phoenix-area warehouse, employees) creates immediate nexus. Economic nexus: $100,000 in gross sales to Arizona buyers in the previous or current calendar year.
2. Register via AZTaxes — apply for a Transaction Privilege Tax (TPT) license through the Arizona Department of Revenue's online portal. Note: AZ uses "TPT" rather than "sales tax" technically; functionally similar. License fee varies by city.
3. Configure state 5.6% + county/city — AZ state TPT is 5.6%, plus county (0.5%–1.1%) and city (0%–4.5%) rates. Combined rates run 5.6%–11.2%. Phoenix, Tucson, Flagstaff each have specific city TPT rates. ZIP-based rate lookup is essential.
4. Capture exemption certificates — Form 5000 (Transaction Privilege Tax Exemption Certificate) for resellers and other categories. Hold for 4 years. AZ also has unique "factored tax" calculations for some categories.
5. File via AZTaxes — frequency varies (monthly, quarterly, annual based on liability). Returns due the 20th of the following month. AZ requires electronic filing for almost all sellers as of recent rule changes.

Real Arizona compliance situations

• A Phoenix retailer charges 8.6% combined (5.6% state + 0.7% Maricopa County + 2.3% Phoenix). Each Arizona city sets its own TPT rate; Scottsdale is higher (8.05%), Glendale 9.2%, Tempe 8.1%. They use ZIP-based logic with monthly verification via the AZ DOR rate lookup.
• A Tucson-based SaaS company confirmed Arizona does NOT tax SaaS or pre-written software accessed electronically (a useful exemption). They charge no AZ TPT on SaaS subscriptions but do charge on bundled hardware deliveries.
• An Arizona e-commerce seller discovered the "factored tax" rule for retail sales — when the seller absorbs the tax in the listed price, AZ requires a specific factoring calculation rather than simple percentage extraction. Their accounting tool handles this automatically.

More Arizona FAQs

Is SaaS taxable in Arizona? No — Arizona does not tax SaaS or pre-written software accessed remotely. Software delivered on physical media may be taxable depending on the city. Custom software is exempt.

What's the difference between "sales tax" and "TPT"? Arizona technically imposes a Transaction Privilege Tax on the seller (not the buyer), though it functions like sales tax in practice. The seller is legally responsible for the tax even if not collected from the buyer. This is a meaningful legal distinction during disputes.

Does Arizona have sales tax holidays? No — Arizona does not currently have a state-level sales tax holiday. Some cities have considered local exemptions but no major holidays exist as of 2026.

How does AZ tax contractors and construction? Construction contractors in AZ are subject to a "prime contracting" tax of 5.6% state + applicable city/county rates on 65% of gross receipts (the "factored amount"). This is a unique AZ structure compared to most states' contractor sales-tax treatment.
