The Internal Revenue Service (IRS) announced that interest rates will increase for the calendar quarter beginning
October 1, 2023.

The rates will be 8% for overpayments (7% in the case of a corporation), 5.5% for the portion of a corporate overpayment exceeding $10,000, 8% for underpayments, and 10% for large corporate underpayments.

ADOR applies interest, compounded annually, in the same manner and at the same time as prescribed by the U.S. Internal Revenue Code (IRC), Section 6621. See the ADOR interest rate page for details.



ADOR is using a new email delivery service to send out emails. We are letting you know as you may have noticed a different look. The emails will contain the same information you are accustomed to receiving. The company, Mailchimp, will be identified at the bottom of the email so you can be assured the email is from ADOR.

You do not need to do anything to keep receiving emails from ADOR. If you would like to update your preferences or unsubscribe, visit



Did your primary user leave the company or did you get rid of the email address that is used to log into AZTaxes? No problem. The Arizona Department of Revenue recommends that the primary user is an officer/owner of the business, then delegate access to others if needed. This reduces the chance of losing access to your account and rushing to update information before the due date.

A Primary User maintains the entire online account and provides access to delegate users. There can only be one Primary User for each account. For help authorizing access for delegates, view our tutorial.

A Delegate User is given specific authority for business account functions by the Primary User. This type of user can be a CPA, paid preparer, office manager, additional officer/owner of the company, etc. For help requesting delegate access, view our tutorial.

To change the Primary User, you will need to complete a Business Account Update Form; and you must enroll to file and pay on NOTE: DO NOT use the Business Account Update Form for delegates/additional users. Please contact the primary user for changes to delegate access.

  1. The company will need to register as a new user. See Account Setup for assistance.
  2. Once registered, you will need to complete a paper Business Account Update to change the primary user to the new user account.
  •   Section A, line 4 is for adding and removing AZTaxes Primary Users.
  •   Have Section C signed by an authorized officer/owner and submit to the address on the form.
  1. Once the primary is switched to an office/owner, they can grant delegate access to other registered users.


When taxpayers file electronically, they receive many benefits and are in compliance.

  • It’s EASIER, it’s FASTER, and it’s the LAW for businesses with $500 or more annual tax liability.
  • It is free to file a return; free for e-check payments (Fees apply with debit/credit card).
  • TPT filers are able to claim an accounting credit of 1.2 percent of the tax due, up to a maximum credit of $12,000, during a calendar year when filing all returns electronically.
  • After a payment or return is submitted, filers receive a confirmation number that can be provided to customer service when inquiring about the return or payment.
  • Reduced errors with automatic calculations. Input the figures and AZTaxes does the rest.
  • Access to electronic payment history and status as early as your first payment.
  • Make scheduled payments online so the return is done and the payment is withdrawn later. No need for paper checks.


If you are unable to pay online, follow these simple steps to ensure your payment is applied to your account.

  1. Address the payment to the Arizona Department of Revenue.
  2. In the memo, write your license number and filing period.
  3. Submit your paper check with the original return or a payment voucher. If you filed electronically, send a voucher, not a copy of the return.


Note: ADOR will process your check and withdraw the money from your account even if you do not properly indicate your business information. ADOR will research and attempt to connect the payment to the business. If not successful, the payment will be held in a general fund account until it is properly identified for your business and the time period. ADOR legally cannot mail the check back in case of incorrect address on check and prevent fraud.



  • Do not send duplicate returns as they create duplicate efforts and may delay processing.
  • Do not send confirmation returns. We do not process these.
  • If you’re sending a paper return, please include all information (Taxpayer Information Box).
