What Is Use Tax in Arizona and Do I Owe It?

Arizona’s tax system includes a component known as use tax, which often complements the state’s Transaction Privilege Tax (TPT). It can apply to various purchases where the standard TPT was not collected. This tax exists to ensure fairness in commerce by leveling the playing field between purchases made within Arizona and those made from outside the state. Arizona Revised Statutes Section 42-5-2 outlines the legal framework for this obligation, which applies to the storage, use, or consumption of tangible personal property and certain services.

What Arizona Use Tax Is

Arizona’s use tax functions as a direct counterpart to the state’s Transaction Privilege Tax (TPT). While TPT, frequently referred to as sales tax, is a tax imposed on the vendor for the privilege of doing business in Arizona, use tax is levied on the consumer. Vendors holding an Arizona TPT license collect TPT from customers on taxable sales, but when TPT is not collected, the responsibility shifts to the purchaser in the form of use tax. This self-assessed tax applies to tangible personal property that is used, stored, or consumed within Arizona. Services are generally not subject to use tax in Arizona, though some specific services are subject to TPT and, by extension, could be subject to use tax if TPT was not collected.

When Arizona Use Tax Applies

Arizona use tax liability arises in specific situations where tangible personal property is acquired without the applicable Transaction Privilege Tax (TPT) being collected by the seller. A common scenario involves purchases made from out-of-state online retailers or mail-order companies that do not possess an Arizona TPT license and therefore do not charge Arizona tax. This also applies if a seller located outside Arizona ships items directly to an Arizona resident, and no tax is collected on the transaction.

Another instance where use tax applies is when goods are purchased in another state and subsequently brought into Arizona for use or consumption. For example, if a resident buys furniture or electronics while traveling out-of-state and then transports these items back to Arizona for their own use, use tax may be owed if the tax paid in the other state was less than Arizona’s rate. Businesses frequently encounter use tax when acquiring machinery, equipment, or office supplies from out-of-state vendors that do not collect Arizona TPT. Even purchases from in-state vendors who fail to properly collect TPT, such as a seller operating without a required license, can trigger a use tax liability for the buyer.

The tax applies to items that would typically be subject to TPT if purchased in Arizona. This includes items for both personal use, like household goods, and business use, such as specialized equipment. However, certain transactions are generally exempt from use tax, including casual sales between individuals and items specifically exempt from TPT, such as most food items purchased at a grocery store or prescription medicines. For vehicles, the Arizona Department of Transportation (ADOT) often verifies tax payment at the time of registration if the vehicle was purchased from an out-of-state dealer.

Calculating Arizona Use Tax

Determining the amount of Arizona use tax owed involves identifying the correct tax base and applying the appropriate rates. The tax is calculated on the purchase price of the tangible personal property or taxable service. This purchase price typically includes any shipping and handling charges associated with acquiring the item. If goods are acquired through an exchange, the fair market value of the property exchanged is considered the purchase price.

The applicable use tax rate mirrors the combined state, county, and city Transaction Privilege Tax (TPT) rates for the specific location where the item is used or consumed in Arizona. The state use tax rate is 5.6 percent. To find the precise combined rate for a particular Arizona location, individuals and businesses can utilize the Arizona Department of Revenue (AZDOR) website, which provides a tax rate lookup tool based on physical address or zip code.

A credit may be allowed against the Arizona use tax for any sales or use tax legally paid to another state on the same item. This provision prevents double taxation on a single purchase. If the tax paid in the other state was less than Arizona’s applicable use tax rate, the difference must be remitted to Arizona. For example, if 3% tax was paid in another state on an item subject to a combined 8% Arizona use tax, an additional 5% would be owed to Arizona.

Reporting and Paying Arizona Use Tax

Fulfilling Arizona use tax obligations requires specific procedural steps, which differ based on whether the taxpayer is an individual or a business. Individuals typically self-assess and report this tax directly to the Arizona Department of Revenue (AZDOR). This can often be done on their Arizona individual income tax return, such as Form 140. Alternatively, individuals can remit use tax directly to AZDOR by mail.

Businesses report and pay use tax as an integrated part of their regular Transaction Privilege Tax (TPT) return. This is typically done using Form TPT-2. The AZDOR encourages electronic filing and payment for businesses through its online portal, AZTaxes.gov.

Payment methods for both individuals and businesses include electronic funds transfer (EFT) directly from a bank account, which usually incurs no additional fees. Credit and debit card payments are also an option through AZTaxes.gov, though these typically involve a processing fee. Payments can also be made by check or money order sent through the mail. Filing and payment deadlines for businesses align with their assigned TPT filing frequency (monthly, quarterly, or annually), while individuals reporting use tax on their income tax return adhere to the standard income tax deadlines, generally April 15th of the following year.
