1. Introduction

For software companies, SaaS providers, and technology firms conducting business in Arizona, understanding the state's Transaction Privilege Tax (TPT) rules is essential. Unlike many states that use a traditional sales tax system, Arizona's TPT is a tax on the vendor for the privilege of doing business in the state. This distinction is important, as it means the vendor—not the customer—bears the legal responsibility for the tax, even though the tax may be passed on to customers.

Arizona has developed specific regulations regarding the taxation of software, digital goods, and technology services under Arizona Revised Statutes § 42-5001 and related provisions. The state makes important distinctions between prewritten (canned) software, custom software, and cloud- based services, with tax treatment varying based on delivery methods and customization levels. Most critically for technology companies, Arizona takes the position that electronically delivered software and SaaS offerings are taxable under the retail and personal property rental classifications, respectively—a significant contrast to states like Florida that exempt these digital products.

Purpose of This Guide

This guide helps businesses navigate Arizona's TPT rules related to software and technology
services, focusing on:

• Nexus Considerations: Understanding when businesses must register and collect Arizona
  TPT due to physical or economic presence.
• Taxability of Software & Services: Clarifying the tax treatment of prewritten vs. custom
  software, cloud computing services, and related technology offerings.
• Sourcing Rules: Determining how and where transactions are taxed based on customer
  location and method of software delivery.
• Audit Considerations: Identifying common tax audit triggers and best practices for
  compliance.
• Voluntary Disclosure Agreements (VDAs): Explaining the process for businesses to
  rectify past noncompliance while mitigating penalties.

Why This Matters for Technology Companies

Arizona's TPT laws impact software companies, SaaS providers, and technology firms in
multiple ways:

• TPT Obligations: Businesses selling software or related services to Arizona customers
  may have a duty to collect and remit Arizona TPT, depending on how the product is
  classified.
• SaaS Complexity: Arizona treats SaaS as taxable under the personal property rental
  classification, despite no explicit statutory language addressing digital services.
• Compliance Risks: Failure to correctly assess and collect TPT can result in significant
  penalties, interest, and extended audit exposure.

This guide walks through Arizona's specific TPT rules governing software, SaaS, and
technology-related services while referencing applicable statutes, administrative rules, and
Arizona Department of Revenue (ADOR) guidance.
