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.

If you wish to create your own software for filing or create software to sell, please refer to the RT-750, Electronic Filing - Telecommunication Returns. Once we have received your enrollment form, we will contact you regarding testing.
