Arizona State Business Tax Extension

To request Arizona business tax extension, use Arizona Form 120EXT (Application for Automatic Extension of Time to File Corporation, Partnership, and Exempt Organization Returns). To avoid late filing penalties from the State of Arizona, your filing of Form 120EXT must be postmarked by the original due date of your return.

The Business tax filing due by April 15, 2020 or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).

An Arizona extension offers an additional 6 months tax extension, which moves the filing deadline to October 15 (for calendar year taxpayers) and Arizona partnerships are given a 5-month tax extension.

An extension of time to file is not an extension of time to pay. The taxpayer must pay at least 90 percent of its tax liability by the original due date of the return. If the estimated tax payments reported on line 2 are less than 90 percent of the amount on line 1, the taxpayer must make an extension payment

Payments reported on line2 is less than 90 percent of the amount on line1.
