Taxpayers receiving Form 1099-G, which serves as a confirmation of the previous year’s state tax refund, can go online to search, download, and print the form. They can go to www.AZTaxes.gov, click the “View My 1099-G,” provide the necessary information and download the forms. In addition to Form 1099-G, taxpayers can confirm the previous year’s state tax refund by reviewing their previous year’s Arizona individual income tax return.

If an individual did not receive a W-2 from an employer, that person should contact the IRS at 800-829-1040 for further instructions. Individuals who lose a W-2, or find their W-2 is incorrect, can request a new one from their employer.
Individuals needing a copy of previously filed and processed tax returns and/or attachments, including Form W-2, can file Arizona Form 450, Request for Certified Copies of Documents. The fee for copies, which taxpayers can find on the form, must be submitted with the completed document.
Please note that processed tax returns consist of the current tax year and prior four years. Jointly filed individual income tax returns may be requested by either spouse and require only one signature on the request form. For transaction privilege, withholding, or corporate tax, the requestor must be the owner of the business or officer of the corporation. Otherwise, an Arizona POA Form 285 is required.
If an Arizona return has mistakes, individuals must complete and submit an amended tax return using Arizona Form 140X.
