Arizona Sales Tax Calculator (2026) — Add or Reverse Tax
Arizona's combined sales tax rate is 8.52% (5.60% state + 2.92% average local). Use the calculator below to add Arizona sales tax to a price, or reverse a tax-included total to find the pre-tax price and exact tax amount.
How to use this calculator:
- Adding tax — enter a pre-tax price, pick "Add tax to price," and the calculator applies the Arizona rate to show the tax amount and final total.
- Reversing (extracting) tax — enter a total that already includes tax, pick "Extract tax from total," and the calculator divides by 1 + the rate to isolate the pre-tax price and the exact tax paid.
- Pick the rate that matches your situation: the average combined rate is a good statewide estimate, but the state-only or maximum-local rate is more precise if you know the exact city or county.
Understanding Arizona Sales Tax
Arizona's state sales tax rate is 5.60%, and local jurisdictions add an average of 2.92% on top, bringing the typical combined rate to 8.52%. Rates vary by city and county — the highest combined rate in Arizona can reach 10.90%.
Arizona also levies a state income tax, which shapes how much the state relies on sales tax revenue relative to other funding sources.

Why Reverse Sales Tax Calculation Matters
Receipts, invoices, and marketplace payouts usually show only the tax-included total — not the pre-tax price. Reversing the calculation matters for bookkeeping (separating revenue from tax collected), expense reports (reimbursing only the pre-tax cost), and price comparisons (checking what an item actually costs before Arizona's tax is applied). Because dividing by (1 + rate) is not the same as simply subtracting the rate from the total, doing this by hand is a common source of errors — the calculator above handles it exactly.

History & Rate Breakdown
Arizona's transaction privilege tax (TPT) was created in 1935. Legally it isn't a traditional sales tax at all — it's a tax on the privilege of doing business in Arizona, levied on the seller rather than the buyer, even though most businesses pass the cost to customers at checkout.
Arizona's 8.52% average combined rate layers a 5.6% state TPT rate with county excise taxes and city TPT rates that each municipality sets independently. Because every city and county can set its own rate and its own rules on what's taxable, Arizona is one of the more complex states for multi-location retailers to administer.
Where the Money Goes
Arizona TPT revenue funds general state operations and is shared with cities and counties under state-set distribution formulas, alongside the state's individual and corporate income tax revenue.
Business Use Case: Registering & Collecting Arizona Sales Tax
An out-of-state online retailer whose Arizona sales exceed $100,000 in a year must register for a TPT license with the Arizona Department of Revenue — not a standard sales tax permit — and then determine the correct combined state, county, and city TPT rate for every delivery address, since Arizona doesn't offer a single simplified flat remote-seller rate.
Sales Tax Terms Glossary
Combined rate
The state sales tax rate plus any applicable local (city, county, or special district) rates — the actual rate charged at checkout in a given location.
Reverse sales tax
The process of working backward from a tax-included total to find the pre-tax price and the exact tax amount, using total ÷ (1 + rate) = pre-tax price.
Economic nexus
A sales threshold (in dollars, transaction count, or both) that obligates an out-of-state seller to collect and remit sales tax even without a physical presence in the state.
Marketplace facilitator
A platform (e.g. Amazon, Etsy, eBay) that collects and remits sales tax on behalf of third-party sellers under most states’ marketplace facilitator laws.
Real-World Example
A $500.00 purchase in Arizona at the average combined rate of 8.52%:
- Tax amount: $500.00 × 8.52% = $42.60
- Total price: $500.00 + $42.60 = $542.60
Arizona Sales Tax Compliance for Sellers
Remote and online sellers establish economic nexus in Arizona once they exceed $100,000.00 in annual sales (no separate transaction-count test). Once nexus is established, a seller must register with the state, collect Arizona sales tax at checkout, and file returns on the state's required schedule. Marketplace facilitators (Amazon, Etsy, eBay, Walmart) generally collect and remit on behalf of third-party sellers automatically.
