Matilda Havelock September 11, 2021 Form
The AZ form-140X is a legal document formally produced by the Arizona Department of Revenue. There are official instructions issued by the relevant departments separately. It is therefore recommended that you check and study the instructions before starting to fill out the form and submit it.
This form is required when you wish to make amend or changes to the Arizona State Income Tax Return that you have received, for either the current or previous tax year.
For this purpose, you are required to complete the form 140X. Don’t use Form 1040X, as it is a document for the IRS Amendment.
To submit the completed ADOR10573 form, print the form and send it to the Arizona Department of Revenue, PO Box 52016, Phoenix, AZ 85072-2016.
