As of March 2015, Arizona sales tax rates are available on the official website for the State of Arizona Department of Revenue. Individuals can view rates for program cities, counties and nonprogram citizens. Sales tax rates also vary depending on what type of establishment a business is considered.
Arizona charges a transaction privilege tax that is commonly referred to as a sales tax. It is a required charge for a business to be able to operate in Arizona. The transaction privilege tax is actually paid by the vendor, but the cost is normally passed on to the vendor's customers. Some cities also charge a privilege tax. The two tax rates are combined to form a city or county's final tax rate.
