Arizona doesn't call it "sales tax." It's a Transaction Privilege Tax (TPT), a tax on the seller rather than the buyer, but the exemptions work the same way in practice: certain purchases and sales don't get taxed, and you need the right paperwork to prove it. This article covers every major category of Arizona TPT exemption, the exact form for each one, and how to apply them correctly.

Key Takeaways

• Arizona has no single "tax exempt" status. Exemptions are tied to specific transaction types (resale, manufacturing equipment, healthcare purchases, and more), not to the buyer's identity alone.
• Form 5000 is the general exemption certificate, but it can't be used for resale purchases. Resale has its own form: 5000A.
• Nonprofits are not automatically exempt from Arizona TPT. A 501(c)(3) still needs to fit a specific exemption category and file the matching certificate.
• Manufacturing, mining, and R&D equipment exemptions are among the most valuable for Arizona businesses, but they only cover machinery "used directly" in production, not office equipment or vehicles.
• The purchaser fills out the exemption certificate, not the seller. Vendors keep it on file to document why they didn't collect tax.

What is exempt from Arizona sales tax?

Arizona's exemptions live in the statutes governing the retail classification (A.R.S. § 42-5061) and the parallel use tax exemptions (A.R.S. § 42-5159), which mirror each other so goods bought out of state aren't taxed differently than goods bought in state. The Arizona Department of Revenue's TPT Exemptions page organizes these by business classification, since exemptions and deductions differ depending on whether you're in retail, contracting, restaurant, or another classification. Here are the categories that come up most for Arizona businesses.

Sales for resale

If you buy tangible personal property specifically to resell it in the ordinary course of business, that purchase isn't subject to TPT. The seller isn't doing you a favor; the sale simply isn't taxed yet, because you're the one who will collect tax when the item reaches the end customer. This is documented with Form 5000A, the Arizona Resale Certificate, not the general Form 5000.

Manufacturing, mining, and R&D equipment

Machinery and equipment used directly in manufacturing, processing, fabricating, job printing, refining, metallurgical operations, mining, or research and development is exempt under A.R.S. § 42-5159(B). The Arizona Commerce Authority's manufacturing exemption program covers the same ground from the business-incentive side, along with a related exemption for electricity and natural gas sold to qualifying manufacturing or smelting businesses.

The boundary that trips people up is "used directly." Office equipment, janitorial supplies, hand tools, furniture, and vehicles used in a manufacturing facility generally don't qualify, even though the business itself is a manufacturer. The exemption follows the equipment and its role in production, not the industry the business is in.

Computer data centers get their own targeted version of this: equipment purchased for a data center certified by the Arizona Commerce Authority's Computer Data Center Program is exempt from TPT and use tax at the state, county, and local level for up to 10 years (20 for qualifying redevelopment projects).Changer aléatoirement pour

Nonprofits (the exemption most people get wrong)

You'll see this claim repeated all over the internet: "nonprofits are exempt from Arizona sales tax." It isn't true. Arizona ties its nonprofit exemptions to named categories under A.R.S. § 42-5159(A)(13) and (15): qualifying hospitals, qualifying health care organizations, qualifying community health centers, and a handful of others. A 501(c)(3) that doesn't fit one of those categories pays TPT like anyone else.

The University of Arizona's own tax office states this plainly: despite being a public university, "the University is not an exempt entity for Arizona sales and use tax purposes and generally pays sales tax on taxable purchases." If a state university isn't automatically exempt, a typical nonprofit isn't either. Organizations that do qualify document it with Form 5000 plus their IRS 501(c)(3) determination letter attached, and some qualifying categories don't even need to reapply annually, per ADOR's exemption letter guidance.

Healthcare and medical purchases

Hospitals organized for charitable purposes, licensed nursing care institutions, and qualifying health care organizations can purchase tangible personal property tax-exempt when it's used for their health-related mission, documented on Form 5000HC, the TPT Healthcare Exemption Certificate. Separately, everyday medical items are exempt regardless of who buys them: prescription drugs, prosthetic appliances, prescription eyeglasses and contact lenses, insulin and glucose test strips, and hearing aids each fall under their own paragraph of the exemption statute.

Food, groceries, and everyday items

Food purchased for home consumption is exempt from the state-level TPT, but this is one of the more misunderstood exemptions because many Arizona cities still tax grocery food locally even though the state doesn't. Check your city's code before assuming groceries are tax-free everywhere in Arizona. Textbooks required by a state university or community college and sold through a bookstore are also exempt.

Government sales, interstate commerce, and everyday deductions

Sales to the federal government, tangible personal property already taxed by another state at an equal or higher rate, and property that the U.S. Constitution prohibits Arizona from taxing (a category that covers most interstate commerce transactions) are all exempt or excluded from the tax base. Motor vehicle fuel is excluded from TPT because it's taxed separately under Arizona's fuel tax statutes, not because it's tax-free.

How do I apply for a sales tax exemption in Arizona?

Unlike an income tax credit you claim on a return, most Arizona TPT exemptions are handled at the point of sale using an exemption certificate. The process runs through the buyer, not ADOR directly:

1. Identify which exemption category applies using the ADOR Deduction Codes list, which maps each exemption to the business classification it applies under.
2. Choose the correct form. Form 5000 covers most general exemptions (leasing, contracting materials, manufacturing equipment, government sales). Form 5000A is exclusively for resale. Form 5000HC covers healthcare purchases. Form 5000M covers non-TPT-licensed contractors buying exempt materials for a specific project.
3. Fill out the certificate completely as the purchaser and provide it to the vendor at the time of sale, not after. Only one exemption category can be claimed per certificate.
4. Attach supporting documentation where required, such as an IRS 501(c)(3) determination letter for nonprofit exemptions.
5. Keep a copy. The vendor retains the certificate to document why they didn't collect tax; if it's ever questioned in an audit, the paperwork is what protects both sides. Organized bookkeeping is what makes this possible years later, since an exemption certificate you can't produce isn't much of a defense.

Certificates can cover a single transaction or a blanket period of up to 48 months, though ADOR generally recommends limiting a blanket certificate to 12 months so it stays tied to a currently valid TPT license.

Who is eligible for tax exemptions in Arizona?

Eligibility depends on matching your purchase to a specific exemption category, not on being a certain type of business or organization in general. In practice, the businesses and buyers who most often qualify include:

• Retailers and wholesalers purchasing inventory for resale
• Manufacturers, processors, refiners, and miners buying equipment used directly in production
• Businesses conducting qualifying research and development
• Hospitals and qualifying health care organizations
• Government agencies and their direct purchases
• Buyers of specific medical items (prescriptions, prosthetics, hearing aids) regardless of business type
• Certified computer data center operators and qualified colocation tenants

Real estate investors and landlords should note that commercial lease income is taxed differently than retail sales, and the state-level TPT rate on commercial leases has been 0% since 1998 (cities may still tax commercial rentals separately). That's a distinct topic from the exemptions covered here, but it's worth knowing the two aren't the same question, especially if how you've structured your rental entities affects which classification your income falls under.

Moving forward with confidence

Arizona's exemption system rewards precision. Every category has its own form, its own statute, and its own boundary on what qualifies, and claiming the wrong one (or claiming a real exemption on the wrong form) creates the kind of paperwork gap that shows up in an audit years later. Getting the certificate right at the time of sale is far easier than reconstructing the justification after the fact. K&R's CPAs and Enrolled Agents work through exemption questions like these with Arizona businesses across manufacturing, healthcare, real estate, and retail.

Talk to K&R about which TPT exemptions actually apply to your business so your exemption certificates hold up if ADOR ever asks. If a past exemption claim has already triggered a notice or an audit, IRS and state representation can help you respond before it becomes a bigger liability. Book a consultation and we'll walk through your specific purchases and sales.

Frequently asked questions

What is exempt from Arizona sales tax? Major categories include sales for resale, manufacturing and mining equipment used directly in production, qualifying nonprofit and healthcare purchases, prescription drugs and specific medical items, food for home consumption, government sales, and property already taxed at an equal or higher rate in another state. Each category has its own statutory citation and exemption certificate.

How do I apply for a sales tax exemption in Arizona? Complete the correct exemption certificate (Form 5000 for general exemptions, 5000A for resale, 5000HC for healthcare) as the purchaser and give it to the vendor at the time of sale. The vendor keeps it on file instead of collecting tax on that transaction. There's no separate application filed with ADOR for most exemptions.

Who is eligible for tax exemptions in Arizona? Eligibility is based on the type of purchase, not a blanket status. Resellers, manufacturers using equipment directly in production, qualifying hospitals and health organizations, government buyers, and purchasers of certain medical items can all qualify, but only for the transactions that fit their exemption category.

What items are eligible for a sales tax deduction in Arizona? Tangible personal property used directly in manufacturing, mining, or R&D; property purchased for resale; prescription drugs, prosthetics, and hearing aids; food for home consumption; textbooks required by Arizona universities or community colleges; and property already taxed in another state are among the most commonly claimed deductions.

Are nonprofits automatically exempt from Arizona sales tax? No. A 501(c)(3) designation alone doesn't create a TPT exemption. Arizona limits nonprofit exemptions to specific categories such as qualifying hospitals, qualifying health care organizations, and a handful of other named categories. Most nonprofits pay TPT on their purchases the same as any other buyer unless a specific statutory exemption applies.

Does Form 5000 cover resale purchases? No. Form 5000 explicitly excludes sale-for-resale transactions. Resale purchases require Form 5000A, the Arizona Resale Certificate, which requires the purchaser's active TPT license number.
