To make a payment on corporate Arizona income tax owed, taxpayers can either do so electronically or by mail.
Corporations are required to pay their tax liability by electronic funds transfer (EFT) if the corporation owes:
Corporations may use AZTaxes.gov or ACH Credit to make EFT payments.
To file an extension on a return, corporations use Arizona Form 120EXT to apply for a maximum six-month extension to file. The completed extension form must be filed by the original due date of the return, unless the original due date falls on Saturday, Sunday, or a legal holiday. In that case, the application must be postmarked on or before the business day following such Saturday, Sunday, or legal holiday.
Please note: This is not a request for extension to pay.
The taxpayer will be liable for the extension underpayment penalty if at least 90 percent of the tax liability disclosed by the return has not been paid by the original due date of the return. For proper application of payment and to avoid delays, corporations must submit payments together with the completed Arizona Form 120EXT.
The department will also accept a valid federal extension for the same period of time covered by the federal extension.
