- Updated April 17, 2021 - 8.00 AM by Admin, ExpressExtension

Does Arizona support tax extension for personal income tax returns?

  • Yes. The state of Arizona requires individuals to file a Federal Form 4868 rather than requesting a separate state tax extension.
  • State Tax extension Form can be filed only if the federal tax extension Form 4868 was rejected.

What Form does the state of Arizona require to apply for an extension?


Individuals in Arizona need to file Form 204 with the state to request a 6-month extension of time to file their personal income tax return with the state.

  • Form 204- Request For Extension Of Time For Filing Individual Tax Returns

Note: Make sure to pay any taxes due along with the extension Form to avoid penalties and interest.

When is the deadline to file Form 204 with the state of Arizona?


Arizona State individual tax extension Form 204 must be filed on or before the 17th day of the 5th month after the tax year ends (May 17 for calendar year filers).

How do I pay my balance due along with the extension Form?


If you owe Arizona state taxes, you must pay your tax due by the regular due date, or you will be charged with penalties and interest.

To avoid underpayment penalties, make a tax payment with your extension form using Form 204 on or before April 15, 2021.

You can pay tax due online using or mailing your Form.

Also, use Form 204 to remit an extension payment whether you are requesting an Arizona extension or using a valid federal extension.

However, if you are filing under a federal extension, but making an electronic extension payment or making an extension payment using a credit card, you do not need to mail in Form 204.

Arizona will accept your federal extension for the period covered by the federal extension.
