2005 Arizona Revised Statutes - Revised Statutes §43-327  Recomputation of tax or amended return due after federal adjustment

A. If the amount of taxable income for any year of any taxpayer as reported to the United States treasury department is changed or corrected by the commissioner of internal revenue or other officer of the United States or other competent authority, or if a renegotiation of a contract or subcontract with the United States results in a change in taxable income, such taxpayer shall within ninety days after the final determination of such change or correction or renegotiation either:

1. File with the department a copy of the final determination, concede the accuracy of the determination or state any errors and request the department to recompute the tax owed to this state. Recomputing the tax by the department is not considered to be an audit for purposes of section 42-2059.

2. File an amended return as required by the department of revenue.

B. The department may require an amended return if the department lacks the necessary information to recompute the tax owed to this state.

C. Any taxpayer filing an amended return with the United States treasury department shall also file within ninety days an amended return with the department of revenue which shall contain such information as it shall require.
