Electronic Filing for Telecommunications Tax

Those taxpayers that have an average monthly liability over $1,000 must file all returns and schedules electronically. Voluntary participation in the program is welcomed. We offer electronic direct transmission. The following returns and schedules are accepted: RT-2, RT-2-X, and RT-2-M.

To use this method of electronic filing, you can buy software from an accepted electronic filer (third party) or write your own software. Note: Telecommunications Tax returns can be filed online at MyTax Illinois. Participants using our free MyTax Illinois program do not complete Form IL-8633-B.

If you wish to create your own software for filing or create software to sell, please refer to the Implementation Guide for Direct Electronic Filing of Telecommunications Tax (below). To enroll, complete Form IL-8633-B, Business Electronic Filing Enrollment.

Note: Some taxpayers are required to pay their tax electronically using Electronic Funds Transfer.
