Arizona does not have a sales tax in the strict sense. It has the Transaction Privilege Tax (TPT), which the Arizona Department of Revenue describes as a tax on a vendor for the privilege of doing business in the state. It is filed online in AZTaxes, at AZTaxes.gov, and the tax accrued is due on the 20th of the month after the end of the tax period. Electronic filers have a grace period to the last business day of that month, but penalties and interest run from the 20th. Even when you had no sales, you must file a $0 TPT return.
This guide covers who files and how often, how to file in AZTaxes, how to report no sales, how to amend a return, how to pay, and what to watch for on late filing.
This article is educational information, not tax advice. Filing rules, thresholds, and penalties can change, so confirm current requirements with the Arizona Department of Revenue before you file.

Who has to file, and how often
Businesses that sell taxable goods or services in Arizona need a TPT license and file TPT returns. Arizona TPT is levied on the seller, though sellers commonly pass it on to customers. Our Arizona sales tax guide covers registration and taxability in more detail. Selling software? Our post on Arizona SaaS sales tax explains how it is treated there, and our post on sales tax on clothes in Arizona covers a common retail question.
ADOR sets your filing frequency from your estimated annual combined state, county, and city tax liability, not your sales volume. When you apply for a license you estimate your projected liability, and ADOR uses it to set the initial frequency.
| Frequency | Estimated annual combined tax liability | Due date |
|---|---|---|
| Annual | Less than $2,000 | The 20th of the month after the period ends |
| Quarterly | $2,000 to $8,000 | The 20th of the month after the quarter ends |
| Monthly | More than $8,000 | The 20th of the following month |
| Seasonal | 8 months or less of business activity | Per your assigned periods |
To change your frequency, complete and mail the Business Account Update Form. Online changes are not available. The change takes effect at the beginning of the next filing period, and it cannot be made if your TPT account has delinquencies.
Before you start: get into AZTaxes
You need a TPT license before you can file; our sales tax permit overview explains how registration works in general. To use AZTaxes business services, you register an AZTaxes account by enrolling your email address at AZTaxes.gov. The primary user is the account administrator, and ADOR advises that this be an officer or owner of the business. The primary user can grant delegate users, such as a CPA or office manager, access to specific functions.
Before filing, gather your records for the period: gross receipts by business classification and location, and any deductions you claim. Businesses with more than one location, or with additional region or deduction codes, must file online at AZTaxes.gov. For sales to resellers, see our Arizona resale certificate guide for what to collect from buyers.
Step-by-step: filing a TPT return in AZTaxes
- Log in to AZTaxes.gov with your business account.
- Open your TPT account and start the return for the period you are filing.
- Enter sales by location and classification. Report receipts by business classification and the city or region where the sale is sourced.
- Claim deductions with the right code. Use the deduction code that matches your business classification.
- Review the calculated tax. Check the totals against your records before you submit.
- Submit and pay. File and pay before 11:59 p.m. on the electronic deadline.
Mismatched city and region codes, incorrect deduction codes for a business classification, and calculation errors are common reasons ADOR rejects TPT returns. If a return is rejected, file an amended return to correct it.

Local and rate pitfalls: state, county, and city
Arizona TPT rates combine state, county, and city rates, and they vary by business classification as well as by location. Cities and towns also change their rates: ADOR's June 2026 update lists rate changes effective July 1 and August 1, 2026 for several jurisdictions. Some jurisdictions use a tiered structure for single-item purchases above a set dollar amount, either applying the higher rate to the whole sale or only to the portion over the threshold.
ADOR publishes monthly rate tables as PDFs, downloadable CSV files of rates by business classification, and an address lookup tool at AZTaxes.gov that returns the state, county, and city rates for a physical address or zip code. Look up each location rather than reusing one rate. Our Arizona sales tax calculator shows current rates by location.
Due dates and the weekend rule
The statutory due date is the 20th of the month following the end of the period. ADOR's 2026 calendar shows three dates for a monthly return, using July activity as the example:
| Deadline | Date for July activity |
|---|---|
| Statutory due date | August 20 |
| Paper returns must be received | August 28 |
| Electronic returns and payments (11:59 p.m.) | August 31 |
Quarterly returns work the same way, with October 20, 2026 as a quarterly due date on the calendar. See the Arizona sales tax due dates page for a quick view, and ADOR's due date page for the official 2026 calendar.
Businesses with combined tax liability of $4,100,000 or more in the preceding calendar year must also make an annual estimated payment each June, electronically, with a statutory deadline of June 22 in 2026.
Filing a $0 return
You must file even if you had no sales or no tax due. ADOR states that for any filing period you must still file a $0 TPT return. File it in AZTaxes for each assigned period, as you would any other return.
Amending a return
To correct a filed return, log in to your TPT account on AZTaxes.gov, complete a new TPT return that includes your original entries plus the new adjustments, check the Amended Return box, and submit. Keep supporting documents for the adjustments, because an auditor may ask for them. An amended return must be filed within four years of the original due date or the filing date, whichever is later, and it cannot change how estimated tax payments were applied.
Payment methods
- ACH debit and e-check: Pay through AZTaxes.gov. Only registered users can pay by e-check.
- Credit card: Also available through AZTaxes.gov.
- Guest payment: You can make a TPT or use tax payment as a guest with your license number and business zip code, with no login.
ADOR moved its ACH debit payment services to a new bank in June 2026. If you pay by ACH debit, ask your bank to update the company ID, which ADOR lists in its June 2026 TPT update.
Penalties and interest
ADOR applies penalties and interest from the statutory 20th due date, even if you file within the electronic grace period. So file and pay by the 20th where you can. For current penalty and interest rates, check ADOR before you file.
Common mistakes to avoid
- Assuming the grace period stops penalties. Penalties and interest run from the 20th.
- Skipping $0 returns. Every assigned period needs a return.
- Using one rate for every sale. State, county, and city rates differ, so look up each location.
- Using the wrong deduction or region code. These are common causes of rejected returns.
- Waiting to change your frequency. Changes require a mailed form, and are blocked when the account has delinquencies.
