Tax-Prep Software for Business Income Tax (BIT) Filers
Participation in the Illinois Electronic Filing Program for Corporate Income Tax returns is available to software developers, transmitters, Electronic Return Originators (EROs), and taxpayers. To use this method of filing, you can write your own software or buy software from an accepted electronic filer (third party).
If you wish to create your own software for filing or create software to sell, please refer to the BTR-36, Implementation Guide for Business Income Tax Federal/State Electronic Filing Program. To enroll, complete Form IL-8633-B, Business Electronic Filing Enrollment. Once we have received your enrollment form, you may begin testing.
If you choose to have a third party file your return, you may wish to choose from the following software vendors currently approved by the department to electronically file some or all Illinois business income tax returns and corresponding forms and schedules.
Note: Software vendors are deemed approved after they register and have their product approved through testing. These companies may be web-based companies or traditional software development companies that produce a product for the purpose of formatting and transmitting electronic returns.
