Arizona has announced that the tax filing deadline for individual returns is April 15th.
Arizona Filing Due Date: Individual income tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Arizona Tax Extension: Arizona offers a 6-month tax extension, which moves the state filing deadline to October 15 (for calendar year filers).
Arizona Tax Extension Form: To request an Arizona extension, file Form 204 by the original due date of your return.
Arizona Extension Payment Requirement: An extension of time to file is not an extension of time to pay your Arizona income tax. All state tax payments are due by the original deadline of the return. Any tax not paid by the proper due date will be subject to penalties and interest. You can use Form 204 to submit an Arizona extension payment, or pay electronically through the AZTaxes system: www.aztaxes.gov/MakePayment
Arizona Tax Extension Tip: If you have a valid Federal tax extension (IRS Form 4868), you will automatically receive a corresponding Arizona tax extension for the same period of time. In this case, Form 204 does not need to be filed unless you’re making an Arizona extension payment.
