Arizona Tax Extension
The Arizona Department of Revenue will follow the Internal Revenue Service (IRS) announcement regarding the start of the 2020 electronic filing season. Arizona’s electronic filing system for individual income tax returns is dependent upon the IRS' launch date because the state’s electronic income tax returns are processed and accepted through the IRS first.
The State of Arizona has announced it has moved the deadline for filing and paying state individual income taxes from April 15 to May 17, 2021. The deadline for first quarter tax year 2021 individual estimated tax payments remains April 15, 2021.
