The sales tax in Tucson is 8.7 percent on most retail purchases. That combined rate is built from three separate pieces: Arizona’s state rate of 5.6 percent, Pima County’s 0.5 percent excise, and the City of Tucson’s local rate of 2.6 percent.1Arizona Department of Revenue. Arizona State, County and City Transaction Privilege and Other Tax Rate Tables2Arizona Department of Revenue. City of Tucson Arizona technically calls this a Transaction Privilege Tax, because the law taxes the business for the privilege of doing business rather than the buyer for the purchase. In practice it reaches your receipt the same way a sales tax does.
The Arizona Department of Revenue collects all three portions through a single return and distributes the county and city shares, so businesses file once rather than three times.3Arizona Department of Revenue. Transaction Privilege Tax
When the Rate Isn’t 8.7 Percent
Several common categories carry their own rates in Tucson, so the headline percentage won’t match what you actually pay or collect.
Groceries
Food for home consumption is exempt from the Arizona state portion and from Pima County’s share. Tucson still applies a city-level tax on groceries, but at 2.0 percent rather than the standard 2.6. That is the full rate on your grocery bill. The city grocery tax is politically contested; neighboring South Tucson voted to eliminate its own city grocery tax effective July 2026.4Arizona Department of Revenue. South Tucson
Hotels and Short-Term Rentals
Lodging is taxed at higher city rates. Effective March 1, 2026, the city rate on hotels is 9.0 percent, and the rate on non-hotel short-term rentals (stays under 30 days, including bookings through platforms like Airbnb) is 10.0 percent.2Arizona Department of Revenue. City of Tucson Those city rates stack on top of the state and county portions, so a guest’s total is well above 10 percent. Tucson’s per-night bed surtax dropped to zero as of March 2026.
Residential Rentals
Landlords renting residential property for 30 days or more owe no city TPT. Arizona eliminated all city-level tax on long-term residential rentals effective January 1, 2025, and neither the state nor county imposed one previously.5Arizona Department of Revenue.

What’s Exempt
Some purchases are outside the tax entirely. Prescription medications and prosthetic devices prescribed by a licensed health care provider are excluded from the tax base under state law.6Arizona Legislature. Arizona Revised Statutes Title 42-5159 – Exemptions Resale transactions are exempt when the buyer gives the seller a properly completed exemption certificate. Manufacturing equipment used directly in production can also qualify, though the requirements are specific and worth confirming with ADOR before you rely on them.
Exemption Certificates
If you sell to a buyer claiming an exemption, keep documentation. Most exempt purchases use ADOR Form 5000. Resale uses Form 5000A. Contractors not licensed for TPT use Form 5000M.7Arizona Department of Revenue. Transaction Privilege Tax Exemption Certificate The buyer completes the certificate at the time of sale and the vendor retains it. If ADOR audits you and you can’t produce the certificate, you owe the tax, penalties, and interest as though the sale were fully taxable.
If You’re the Business Collecting the Tax
You need a TPT license before your first taxable sale in Tucson. The state license costs $12 per business location, with a separate city license fee on top, and you apply through the Arizona Joint Tax Application (Form JT-1).8Arizona Department of Revenue. TPT License9Arizona Department of Revenue. Applying for a TPT License Licenses must be renewed by January 1 each year, and renewals received after January 31 trigger a late fee equal to 50 percent of the city renewal fee.10Arizona Department of Revenue. TPT Update If you close the business, cancel the license; an unrenewed active license still generates fees.
How Often You File
Filing frequency depends on your estimated annual combined TPT liability:
- Monthly if you owe more than $8,000 per year.
- Quarterly if you owe between $2,000 and $8,000.
- Annually if you owe less than $2,000.11Arizona Department of Revenue. TPT Update
If your annual TPT and use tax liability reached $500 or more during the prior calendar year, you must file and pay electronically through AZTaxes.gov. Only businesses with a single location and under $500 in annual liability can use the paper Form TPT-EZ.12Arizona Department of Revenue. E-Services for TPT
Due Dates and the Grace Period
The statutory due date is the 20th of the month after the reporting period. Arizona then provides a grace period: electronic returns are timely if received by the last business day of the month they’re due, and paper returns are timely if received by the second-to-last business day.13Arizona Department of Revenue. TPT Filing Frequency Watch the catch. If you file late, penalties and interest are calculated from the 20th, not from the end of the grace period. The grace window only protects you if you actually meet it.
What Late Costs
Two penalties can run at the same time: 4.5 percent of the tax due for each month or partial month the return is late, plus 0.5 percent of the unpaid tax for each month or partial month the balance remains outstanding.14Arizona Department of Revenue. Filing Notices of Penalties and Interest A business owing $5,000 that sits on the return for three months runs up $675 in late-filing penalties and another $75 in late-payment penalties before interest.
Interest compounds annually on the unpaid balance at the federal short-term rate plus three percentage points. For the first quarter of 2026 that is 7 percent; for the second quarter it drops to 6 percent.15Arizona Department of Revenue. Interest Rates On January 1 each year, ADOR adds outstanding interest to the principal, so the next year’s interest runs on the larger figure. A dishonored electronic payment or bounced check adds a flat $50 fee per occurrence.
Buying or Selling a Tucson Business
This is where buyers get hurt. Under Arizona law, if you buy a business or its inventory, you can become personally liable for the seller’s unpaid TPT. The statute requires the buyer to withhold enough from the purchase price to cover any taxes, interest, and penalties the seller owes.16Arizona Legislature. Arizona Revised Statutes Title 42-1110 – Successor Liability for Tax
Before closing, have the seller request a Tax Clearance Certificate from ADOR. The department has 15 business days to respond with either a certificate or a written explanation of why it can’t issue one. A buyer who obtains the certificate before closing is protected from liability for tax deficiencies the department discovers in a later audit. A buyer who skips it inherits whatever the seller owed.
The certificate application (Form 10523) must be signed by a principal corporate officer and submitted by email, fax, or mail. All liabilities must be paid in full before issuance; a payment plan is not enough.17Arizona Department of Revenue.
