Short answer
In Arizona, a business that sells tangible personal property at retail must hold an annual transaction privilege tax (TPT) license from the Arizona Department of Revenue before it engages in business. A.R.S. 42-5005 sets the application fee at $12, makes the license valid for one calendar year, and states there is no fee to renew it. A city or town that levies its own privilege tax can also require a separate municipal license. For a lab or clinic buyer, the useful point is who needs the license: the selling business, not the purchaser.
Definition and scope
The TPT license is the state-level license that goes with Arizona’s transaction privilege tax. Under A.R.S. 42-5061, the retail classification covers “the business of selling tangible personal property at retail,” and its tax base is the gross proceeds of sales or gross income from that business. A.R.S. 42-5001 defines “tangible personal property” as personal property that may be seen, weighed, measured, felt or touched, which is the category that medical and laboratory supplies, equipment and consumables fall into.
The statute defines “sale” broadly: any transfer of title or possession, or both, exchange, barter, lease or rental. A business that rents equipment is therefore not automatically outside the definition.
What the license rules say
The table below restates only what A.R.S. 42-5005 says on its face.
| Question | What the statute says | Subsection |
|---|---|---|
| Who applies, and when? | A person who desires to engage or continue in a taxable business applies to the department for an annual TPT license, and may not engage or continue in business until it is obtained. | 42-5005(A) |
| Application fee | $12, submitted with the application. | 42-5005(A) |
| How long is it valid? | Only for the calendar year in which it is issued; it may be renewed for the following calendar year. | 42-5005(C) |
| Renewal fee | “There is no fee for the renewal of the transaction privilege tax license.” | 42-5005(C) |
| Several locations or business names | A license is required for each location or business name, even when all are reported on one consolidated return. | 42-5005(I) |
Retail, wholesale and the license
The retail line is drawn in the definitions. “Selling at retail” means a sale for any purpose other than for resale in the regular course of business (A.R.S. 42-5061). A “wholesaler” is a person who sells tangible personal property for resale and not for consumption by the purchaser (A.R.S. 42-5001). When a business has both retail and wholesale sales, the tax applies only to the gross proceeds of sales made other than at wholesale, provided its books show each class separately; if the books do not, the tax applies to every sale (42-5061).
That distinction is why resale documentation matters in the medical supply trade. A reseller buying stock for resale and a clinic buying the same item for its own use are on different sides of the statutory line. For the paperwork side, see our guides on tax-exempt certificates for medical supplies and resale certificates versus seller’s permits, and for how supply businesses are classed, medical supply wholesaler, distributor and manufacturer.
City privilege tax licenses
The state license is not the only one. A person who wants to do business in a city or town that imposes a municipal privilege tax applies to the Department of Revenue for an annual municipal privilege tax license, with a fee of up to $50 set by that city or town’s ordinance (A.R.S. 42-5005(B)). The municipal license is also valid for the calendar year, and its renewal fee is due January 1 and is delinquent if not received by the last business day of January (42-5005(D)). The statute exempts a marketplace facilitator or remote seller that is required to hold only a TPT license under section 42-5043 from the municipal fee (42-5005(B), (D)). A “remote seller” is defined as a seller delivering into Arizona without a physical presence or other legal requirement to hold a license, other than exceeding the economic threshold in section 42-5044 (42-5001).
Medical items the retail classification excludes
Section 42-5061(A) lists categories of receipts to which the retail classification tax does not apply. Those that concern medical goods are:
- Drugs and medical oxygen, including delivery hose, mask or tent, regulator and tank, if prescribed by a member of the medical, dental or veterinary profession licensed by law to administer them.
- Prosthetic appliances as defined in A.R.S. 23-501, as prescribed or recommended by a licensed health professional of the types the statute names.
- Insulin, insulin syringes and glucose test strips.
- Prescription eyeglasses or contact lenses.
- Hearing aids as defined in A.R.S. 36-1901.
- Durable medical equipment that has a CMS common procedure code, is designated reimbursable by Medicare, is prescribed by a licensed professional of the types named, can withstand repeated use, is primarily and customarily used for a medical purpose, is generally not useful in the absence of illness or injury, and is appropriate for use in the home.
Each exclusion carries its own conditions, so a product is not excluded merely because it is “medical.” The list does not mention laboratory consumables or general lab equipment, so this page makes no statement on how those are treated.
Common misunderstandings
“The license costs $12 every year”
The $12 is the application fee in 42-5005(A). Subsection (C) says there is no fee to renew the state license. The municipal license is different and can carry a renewal fee of up to $50.
“One license covers every location”
The statute requires a license for each location or business name, even where a single consolidated return is filed.
“A TPT license and a city license are the same thing”
They are separate licenses under the same section. The city license applies only where the city or town imposes a municipal privilege tax.
“Medical supplies are all excluded”
Only the categories listed in 42-5061(A) are excluded, each under its own conditions.
FAQ
Who needs an Arizona transaction privilege tax license?
A person who wants to engage or continue in a business on which the transaction privilege tax is imposed, which includes the business of selling tangible personal property at retail (A.R.S. 42-5005(A), 42-5061(A)).
How much does the license cost?
The statute sets the state application fee at $12 and no renewal fee. A municipal license fee is up to $50, set by city or town ordinance.
Does the license expire?
Yes. It is valid only for the calendar year in which it is issued and may be renewed for the next calendar year.
Does a seller outside Arizona need one?
The statute defines “remote seller” and “marketplace facilitator” and refers to sections 42-5043 and 42-5044 for when a TPT license is required. Read those sections for the current threshold.
