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 and marketplace payouts usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping, expense reports, or checking what an item costs before Arizona's tax is applied — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why the calculator above handles it exactly.

How Arizona Fits Into the US Sales Tax System
The United States has no federal sales tax — unlike VAT/GST countries where a national rate applies everywhere, US sales tax is set entirely at the state level, and each of the 50 states (plus DC) independently decides whether to levy one, what the rate is, and what's exempt. Arizona is one of the 45 states (plus DC) that levies a general sales tax. States can also authorize cities, counties, and special districts to add their own local rate on top of the state rate — which is why the "combined rate" shown on this page is a blend, not a single fixed number, and why it can differ from the state rate alone by several percentage points depending on the exact delivery address.
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.
Key terms: combined rate — state rate plus applicable local add-ons; reverse sales tax — working backward from a tax-included total via total ÷ (1 + rate); economic nexus — a sales threshold that obligates an out-of-state seller to collect tax without a physical presence; marketplace facilitator — a platform that remits tax on behalf of third-party sellers.
Real-World Example: Adding Tax to a Price
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
Real-World Example: Extracting Tax From a Receipt Total
A receipt shows a $749.99 tax-included total in Arizona at the average combined rate of 8.52%:
- Pre-tax price: $749.99 ÷ (1 + 8.52%) = $691.11
- Tax amount: $749.99 − $691.11 = $58.88
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.
