Arizona SaaS Sales Tax: What You Need to Know

In Arizona, Software as a Service (SaaS) businesses must comply with particular sales tax obligations. SaaS companies are subject to a Transaction Privilege Tax (TPT), which differs from traditional sales taxes as the states consider these services as taxable tangible personal property.

The SaaS sales tax rate in Arizona is 5.6%, but when local taxes are included, the average rate reaches around 8.37%. The complexity of staying TPT compliant makes these services difficult to manage.

How Arizona Taxes SaaS and Software

You must be wondering: Is SaaS taxable in Arizona?  Before we answer the question, you should know that Arizona has its own unique rules on taxation.

The state uses the Transaction Privilege Tax system to charge SaaS or online software. Under this model, vendors have to pay a specific fee to the state for doing business within the state. 

Software and SaaS products generate a significant amount of revenue in the state of Arizona, and so these products fall under the TPT. This taxation system governs a broad range of business activities, including leasing or renting of tangible personal assets.

Understanding the Arizona Transaction Privilege Tax (TPT)

Arizona’s Transaction Privilege Tax (TPT) is a charge for the privilege of conducting business within the state. Unlike a sales tax, Arizona imposes tax on the seller and not the buyer. The business itself pays the tax to the Arizona Department of Revenue. Firms may raise prices of goods and services to transfer the tax burden to the final consumer.

A variety of business activities are subject to TPT, each being categorized under various classifications. For the software and digital products, it is placed under retail and personal property rental categories.

Prewritten and “canned” software delivered physically or electronically are also taxable. However, custom software created for a specific user is not subject to TPT.

Furthermore, like other digital services, SaaS is subject to tax under the personal property rental classification because in Arizona, access to digital services is considered renting personal tangible property. 

These distinctions for the different tax classifications are important for the businesses in Arizona to understand Software taxability in Arizona so operate according to the sales tax laws.

How Arizona Classifies Different Types of Software

Arizona taxes software and digital goods based on their classification. 

Canned (Prewritten) Software

“Canned” or pre-written software is subject to Arizona’s Transaction Privilege Tax (TPT) regardless of its means of delivery. This includes packaged software sold in stores or those that can be downloaded over the internet. The Arizona Department of Revenue considers these transactions taxable under retail sales.

Custom Software

Software designed for a specific client is not subjected to Transaction Privilege Tax (TPT), since the software is viewed as a professional service. If the software was prewritten and then modified or it has other physical components, it may incur taxes.

For example, a law firm gets a software developer to design and build a client management system tailored specifically for the law firm’s operations. The software gets developed from scratch to meet the firm’s requirements. Therefore, it would not incur TPT since it is considered a professional service.

On the other hand, a business that purchases a general accounting software and pays additional fees for modifications will likely have the pre written portion of the software taxable whereas the customization service will be exempt.

SaaS, Cloud Computing, and Digital Services

Software as a Service (SaaS) and cloud-based services are considered personal rental property in Arizona and they are taxable.

It is to be noted that Arizona is one of the few states that tax SaaS based on administrative reasoning rather than a specific statutory sanction. Moreover, custom software is exempt from tax, but proprietary software, which is intended to be used by multiple clients, is taxable.

When Does a SaaS Business Have Nexus in Arizona?

A SaaS company may create an economic nexus in Arizona that incurs a tax obligation if certain criteria are met. 

First, if the company reaches $100,000 or more in sales revenue during the current or preceding calendar year, they reach economic nexus in Arizona. With employees located in Arizona or working remotely, there may also be a tax liability due to having a physical business presence.

This sales threshold level applies to distant sellers who do not have any physical business in Arizona. When this limit is reached, SaaS companies must obtain a Transaction Privilege Tax (TPT) license (a kind of sales tax permit) and start collecting the appropriate tax from Arizona customers.

A seller should always check the legal requirements of tax laws in a specific region to avoid noncompliance.
