Arizona Sales Tax and SaaS: What Businesses Need to Know

In Arizona, businesses that sell and deliver SaaS (Software as a Service) products must generally charge and remit sales tax on those transactions, subject to the state’s Sales and Use Tax (SUT) regulations. The current Arizona SUT rate is 5.6%, which applies to most taxable goods and services within the state. This includes electronic services like SaaS, unless specifically exempted by law.

How-To Guides: Arizona SaaS Sales Tax

Step: 1 Threshold

Arizona is the first state to use a graduated approach to its economic nexus threshold, effective October 1, 2019. In 2019, it was $200,000/year in gross revenue in current or previous calendar year’s sales. The threshold for 2020 was $150,000, and $100,000 in 2021 and thereafter.

According to state law, sellers who exceed the gross sales threshold are required to register for an Arizona sales tax permit to collect transaction privilege tax (TPT) on sales that ship to Arizona and remit the sales tax to the state. Read more about TPT here.

Arizona does not use a VAT/GST regime; instead it uses a Transaction Privilege Tax (TPT) on vendors.
Arizona is the first state to use a graduated approach to its economic nexus threshold, effective October 1, 2019. In 2019, it was $200,000/year in gross revenue in current or previous calendar year’s sales. The threshold for 2020 was $150,000, and $100,000 in 2021 and thereafter.

There is no explicit threshold like VAT — registration is required if you are “engaged in business” in Arizona, which may include economic presence (e.g., sales into the state) and remote sales following economic nexus rules (post-Wayfair).

Step: 2 Business Registration

Register with the Arizona Department of Revenue (ADOR) for a TPT License and any applicable local licenses where you conduct business. Registration is done through ADOR’s AZTaxes.gov portal.

Step: 3 TIN/VAT Number

You receive a TPT License Number from ADOR used for reporting and remittance of TPT on taxable activities.

Step: 1 Standard Rate

Arizona’s state TPT rate is 5.6 % for retail sales; local jurisdictions (cities/counties) may add additional TPT components meaning total rates vary (often ~8 % combined).

Step: 2 Sales Tax Formula

To calculate your tax amount, use the following formula:

 

Tax Amount = Gross Receipts × TPT Rate

Step: 3 Economic Nexus

Out-of-state sellers making sufficient sales into Arizona may trigger nexus obligations and must register and collect/ remit TPT under economic nexus guidance (post-Wayfair). Economic nexus is established when a remote seller exceeds $100,000 in gross sales into Arizona in the current or previous calendar year; nexus is evaluated based on economic activity and engagement in business within the state

Step: 1 Selling B2C

SaaS and digital services delivered to Arizona consumers are generally taxable under TPT, and vendors must collect TPT on these gross receipts at the applicable combined state and local rate.

Step: 2 Selling B2B

SaaS sold to business customers in Arizona is likewise taxable under TPT; there is no reverse charge mechanism like VAT — the seller must collect/ remit the tax where taxable.

Step: 3 Invoice Requirements

Arizona does not prescribe strict TPT invoice formats in statute, but invoices should typically include:
• Seller name and TPT license number
• Invoice date and sequential invoice number
• Customer name and address
• Description of services (SaaS/digital services)
• Gross amount charged
• TPT collected (separately stated if collected)

Step: 1 Filing Interval

Most TPT taxpayers file monthly returns; some qualifying smaller taxpayers may file quarterly with ADOR approval.

Step: 2 Filing Deadline

Generally, the filing deadline is the 20th of the month following the reporting period (for monthly filers).

Step: 3 Submission

Returns and payments are submitted electronically via AZTaxes.gov. Accepted payment methods include ACH debit, credit card (with fees via third-party processor), or direct debit authorization.

Step: 4 Record Keeping

Vendors must retain accurate books, invoices and receipts supporting gross receipts and tax remittances for at least four years (standard bookkeeping period for ADOR audits).
