How do I handle Arizona sales tax collection?
Arizona uses the Transaction Privilege Tax system rather than traditional sales tax. The practical difference is minimal for most businesses. You still collect from customers and remit to the state. But the terminology matters when you’re registering and filing, and the rules work differently than what you might expect from other states.
Start by getting a TPT license through the Arizona Department of Revenue at AZTaxes.gov. The application asks about your business type, location, and activities. Different business activities have different tax classifications, so select the categories that match your operations. A retail store has different classifications than a restaurant or a contractor.
Arizona’s system is origin-based for most in-person transactions. You charge the combined rate for your business location, not where your customer lives. If your store is in Scottsdale, you charge the Scottsdale rate even when your customer drove over from Phoenix. This is the opposite of how many states handle it, so don’t assume your experience elsewhere applies here.
The rate you collect combines three levels. State tax is 5.6%. Maricopa County adds 0.7%. Then each city has its own rate. Scottsdale is 1.75%, Phoenix is 2.3%, Tempe is 1.8%, Mesa is 1.75%. Your combined rate depends entirely on your exact location and could range from around 7.8% to over 10% in some areas.
Configure your point of sale system or invoicing software with the correct combined rate for your location. If you have multiple locations, each needs its own rate. Getting this wrong means either overcharging customers or undercollecting and covering the difference yourself at filing time.
E-commerce complicates things because Arizona treats remote sales differently. Selling online to customers across Arizona may require collecting based on the customer’s location rather than yours. Many online sellers use automated sales tax management software to handle the jurisdiction lookups and rate calculations.
File and pay according to your assigned schedule based on expected tax liability. Most small businesses file monthly with payments due by the 20th of the following month. Lower-volume businesses may qualify for quarterly or annual filing, which reduces the administrative burden.
Cities occasionally adjust their rates, so check the ADOR rate tables periodically. Using an outdated rate puts you out of compliance even if you set everything up correctly initially. Small business bookkeeping should include periodic rate verification, especially if you’re in a city that’s made recent changes.
Some businesses have special rules. Construction contractors face unique treatment where tax calculations differ from standard retail. Certain services aren’t taxable. Food for home consumption gets taxed at lower rates in most cities. If your business doesn’t fit a standard retail model, verify your specific obligations before you start collecting.

More Questions
What's the difference between an employee and contractor?
Employees work under your direction and you handle their tax withholdings. Contractors control how they complete the work and manage their own taxes. The classification determines your payroll obligations and tax filing requirements.
Read answerHow do I track product costs and landed costs for e-commerce?
Track every cost required to get inventory to your warehouse, not just the supplier invoice. Calculate landed cost per unit by totaling freight, duties, broker fees, and insurance, then dividing by units received.
Read answerHow do I catch up on months of bookkeeping?
Gather all your statements, find the last month that reconciled correctly, and work forward from there. For each month, enter and categorize transactions, then reconcile every account before moving on. Chronological order matters because transactions often reference each other.
Read answerHow do I account for markdowns and clearance sales?
Record revenue at the actual selling price, not the original price. Your cost of goods sold stays the same, which means your margin shrinks on marked-down items. Track markdowns separately to analyze which products and categories underperform.
Read answerWhat records do I need to keep for my small business?
Keep financial records like bank statements, receipts, and invoices for at least seven years. Also retain tax returns, employee records, contracts, and business formation documents for varying periods depending on the type.
