Deadline Approaching for Taxpayers Granted Extension for Tax Year 2020 Filing

October 8, 2021

The Arizona Department of Revenue (ADOR) reminds individual income and corporate taxpayers who received a 2020 calendar year tax filing extension--and have not yet filed--have until Friday, October 15 to submit their tax returns. Fiduciary Arizona returns were due September 30, 2021.

A filing extension provides additional time to file from the due date; five months to file individual returns, six months for corporate returns, and five and half months for fiduciary returns.  

The original due date for calendar year partnership and S corporation returns was March 15, 2021, and the extended due date for both the federal and the Arizona calendar year partnership and S corporation returns was September 15, 2021. 

The IRS extension provides additional time to file federal and Arizona returns. The calendar year, federal, and Arizona individual and corporate returns (except S Corporations) are due October 15, 2021, and calendar year fiduciary returns were due September 30, 2021. 

More than 178,000 individuals and 103,000 corporations received an extension for 2020 tax year returns from the state.


ADOR advises taxpayers to double-check their tax returns to ensure no information is missing and recommends e-filing the Arizona return when e-filing the federal return. Individual, corporate, and partnership e-filing is available and reduces the time to process and amount of paper needed to submit complex and lengthy returns.
