Arizona Sales Tax (TPT) Guide (2026)

Arizona's transaction privilege tax (TPT) is the state's version of sales tax, with a state rate of 5.6%. County and city taxes push combined rates above 10% in some areas; Phoenix is 8.6%. TPT is legally a tax on the seller's privilege of doing business, though sellers pass it through to buyers.

Arizona economic nexus applies once your gross retail sales into the state exceed $100,000 in the current or prior calendar year. There is no transaction-count trigger, and SaaS revenue does not count toward the retail-classification threshold. Physical presence creates nexus immediately.

Arizona's marketplace-facilitator transaction privilege tax (TPT) collection requirement took effect October 1, 2019, under H.B. 2757, codified at A.R.S. § 42-5044. A marketplace facilitator must obtain a TPT license and collect and remit TPT once its Arizona gross sales — combining its own sales and sales made on behalf of marketplace sellers, before deductions, with affiliated persons aggregated — exceed $100,000 for the current or previous calendar year — the facilitator threshold has been $100,000 since the requirement took effect, while the general remote-seller threshold phased down from $200,000 in 2019 to $150,000 in 2020 to $100,000 for 2021 and later. Sales made through a marketplace facilitator that reports and remits TPT are excluded from an individual marketplace seller's own economic nexus calculation.[8]

Arizona assigns monthly, quarterly, or annual filing based on tax liability. Paper returns are due the 20th of the month following the reporting period; electronic returns are due the last business day of that month. Most remote sellers file and pay electronically.

Arizona exempts groceries from the state TPT, though many cities tax food. Prescription drugs and many medical devices are exempt. SaaS is taxable in Arizona under the personal property rental classification.

Arizona buyers use Form 5000A (resale certificate) for purchases bought to resell, and Form 5000 for other exemptions; the buyer gives the completed form to the seller rather than filing it with the state [5]. ADOR recommends limiting a certificate to a 12-month period, and a blanket certificate can cover up to 48 months when the buyer's TPT license is verified each year [5].

Late filing carries a penalty of 4.5% of the tax due per month, and late payment adds 0.5% per month, with the combined penalty capped at 25%. Interest accrues from the due date.

After an audit, ADOR issues a proposed assessment, and you have 45 days to file a written protest [6]. Unresolved protests move to an informal conference or a hearing before an administrative law judge, then to the ADOR Director, the State Board of Tax Appeals, and ultimately the Arizona Tax Court [6].
