How Arizona sales tax works
The state of Arizona is setup to collect revenue from businesses who are considered retailers in the state.

The idea is to provide you with a clear, practical reference so that helping you stay compliant and avoiding penalties will be easier.
How rates are structured
In Arizona, sales tax is a combination of state level rates and additional local taxes from cities, towns, and counties. The full amount that the customer pays at the point of sale is the rate for where seller’s location or buyer’s destination, as determined by applicable sourcing rules. That combined rate is the amount that businesses have to collect from customers.
Since localities can add their own tax on all of these same things as well, it's important to know the actual arizona sales and the combined Everywhere in arizona other than the indian reservation has a 301 sales tax rate. In some places you only see the base state rate, while in others there are also several local taxes. It would be up to each seller to determine the actual combined rate at each location they are making a taxable sale and collect that rate.
What transactions are taxable
In general, sales of tangible personal property at retail are taxable, unless a specific exemption applies. Most states also tax services to some extent; Arizona's treatment of services as taxable or exempt depends on statutory references and administrative interpretation. Standard taxable sales include retail sales of tangible merchandise, certain repairs and rental receipts from admissions with local tax levies.
Exemptions and special categories
Not all sales are taxable. Common exemptions include sales for resale, certain types of machinery and equipment used in manufacturing, sales to qualifying nonprofit organizations (for example,a.orgWS_facebook.com" target="_blank">a volunteer fire department) and groceries or prescription medicines that are specifically exempted under the law. Most sales tax exemptions are claimed by the buyer, who typically gives the seller a completed exemption or resale certificate. Sellers are to obtain and keep those certificates as evidence thereof.
Remote sales and out-of-state sellers rules
Online retailers with significant economic activity in the state must abide by sales ax regulations. So if you make sales — regular or significant sales — into Arizona, then chances are you need to register and collect tax on those taxable sales. If the reporting is applicable based on rules, the marketplace facilitator that facilitates a sale through an online platform may also assume collection responsibilities even though it does not take part in contracting with customers on such sales. Sellers will want to examine their sales history to see if they are obligated to register and collect.
Registration and who must collect
All employers in Arizona who miscarry sales for a gross proceeds of over 500 USD from offers taxable must register with the state tax department and to have tax permission. Upon registration, an account for filing making returns and paying liabilities is established. Businesses that satisfy a threshold requirement for nexus or activity (whether physical presence, number of employees or agency scope, sales volume) must register. After registering, the seller must collect in addition to the correct state rate, the applicable combined rate from buyers and pay over such tax on a filing schedule assigned."
Filing frequency and remittance

Returns should claims taxable sales, exempt sales, deductions and the tax collected. A payment is due with each return, and there are interest charges and penalties for failure to file or to pay on time.
Use tax and customer obligations
When sellers do not charge tax — due to reasons including the seller’s lack of registration, a sale by an out-of state seller with no nexus or another issue — customers may still owe use tax on taxable purchases. 'Use tax is a means of making certain that local communities receive tax on purchases which are put to use locally even if no tax was collected at the point of purchase..
Recordkeeping and documentation
Comprehensive records facilitate compliance and easy filing. Keep accurate records of each sale, exemption and resale including receipts, invoices or other proof-of-purchases; and shipping information to establish the out-of-state residency of your customer. The skill of documentation is important in the case of an audit as it substantiates relief claimed on exempt sales. Keep records for as long as required by law and ease of retrieval from supporting documentation.
