The state of Arizona charges a late payment penalty if you fail to file your return by the due date, you owe tax on your amended return, and you don't pay the tax due on your amended tax return. In the case that you do pay the tax due on your amended return, the Arizona Department of Revenue may charge you a late payment penalty if you are being audited, or that the Arizona Department of Revenue tells you to file an amendment to your tax return, or if the additional total tax you owe to the Department of Revenue is larger than 10% of the total tax liability or amounts to $2,000. Moreover, the Arizona Department of Revenue will charge a late filing penalty if the original tax return is not filed on time. In combination, late filing and late payment penalties can't exceed 25%.

The state of Arizona charges interest on tax payments due in all cases, including if one has obtained an extension.
