The deadline for filing and paying state individual income taxes has moved from April 15 to May 17, 2021.
The Arizona Department of Revenue will follow the Internal Revenue Service (IRS) announcement regarding the start of the 2020 electronic filing season. Because Arizona electronic income tax returns are processed and accepted through the IRS first, Arizona’s electronic filing system for individual income tax returns is dependent upon the IRS' launch date. Remember, the starting point of the Arizona individual income tax return is the Federal Adjusted Gross Income.
Taxpayers can begin filing individual income tax returns through Free File partners and individual income tax returns will be sent to the IRS starting mid-February. Tax software companies also are accepting tax filings in advance of the IRS' launch date.
Please refer to the E-File Service page for details on the e-filing process.
