In fiscal year 2020, ADOR stopped more than $19 million from fraudulent tax returns, which is three times the amount compared to last year.


The Arizona Department of Revenue (ADOR) is aware that on September 15, 2020, an unexpected outage concerning systemic tax preparation software prevented some Arizona taxpayers from timely e-filing their returns by the due date of September 15, 2020.


The Arizona Department of Revenue (ADOR) is sending renewal letters to businesses next month to renew their Arizona Transaction Privilege Tax (TPT) License. You must renew on or before January 1 every year. Penalties will apply to renewals received after Jan 31.


Taxpayers can file now and schedule payments up until the deadline.

The Arizona Department of Revenue (ADOR) reminds transaction privilege tax filers that monthly and quarterly returns are due.  Filing before the deadline is highly encouraged in the event assistance is required.


The Arizona Department of Revenue has taken another step to deliver faster and more cost-effective tax service for Arizonans.


The due dates for the 2019 calendar year returns filed with extensions is almost here.  Individual income taxpayers who received a calendar year filing extension, and have not yet filed a return, have until the IRS shutdown to submit their e-filed individual income tax returns.



Beginning January 1, 2021, the transaction privilege tax electronic (TPT) filing and paying threshold lowers to $500.
