E-File for Corporate

Corporations are now able to electronically file their income taxes to the Arizona Department of Revenue (ADOR). The corporate e-file solution starts with 2019 income tax returns and includes partnership tax returns.

Corporations that plan to use a tax professional to prepare electronic income tax returns should check with them early and ensure they are IRS Authorized e-file Providers.

Corporations that plan to prepare their own income tax returns should discuss electronic filing options and check our Approved Vendors List as vendors get verified and approved to e-file returns. 


Mandatory E-file and E-pay Requirements

For businesses, filing electronically is a requirement under certain circumstances: 

  • Corporate Estimated Tax - Any corporation with $500 prior tax year liability.
  • Mandatory e-file for corporations starting in 2021 for tax year 2020 returns (e-file option in 2020 for tax year 2019)
