Do I need to pay sales tax on online purchases in Arizona?

In Arizona, sales tax generally applies to most transactions, whether they occur in physical retail locations or online. The Arizona Department of Revenue requires online retailers with a presence in the state, known as nexus, to collect and remit sales tax on behalf of their customers. This applies to retailers with a physical location, employees, or significant sales volume within Arizona. For consumers, if the online retailer does not collect sales tax, it is the buyer's responsibility to report and pay use tax on the purchase amount. The use tax rate is the same as the sales tax rate. Certain items may be exempt from sales tax, such as specific groceries or prescription medications, which are not subject to tax payment. Consequently, when shopping online in Arizona, it is advisable to check if the retailer collects sales tax at the time of purchase. You may also want to consult the latest information available on the Arizona Department of Revenue's website for further details on tax rates, exemptions, and other related inquiries.
