First-time electronic filers are encouraged, but not required, to submit a test file. A test file is only required when applying to participate in the Combined Federal/State Filing Program.

Separate reporting to those states is not required. The information returns that may be filed under the Combined Federal/State Filing Program are:
A test file, coded for our program, must be submitted in order to participate in the Combined Federal/State Filing Program. The test file may be submitted from November 1st through February 15th. A test file is only required for the first year, but is highly recommended that a test file be sent every year you participate in the Combined Federal/State Filing program. Combined Federal/State records must be coded using the two-digit codes assigned to the participating states from the table in Publication 1220, Specifications for Filing Forms 1097-BTC, 1098, 1099, 3921, 3922, 5498, 8935, and W-2G Electronically. If the Combined Federal/State test file is acceptable, the IRS will send the filer a letter of approval.
Form 4419, Application for Filing Information Returns Electronically, must be filed no later than 30 days before the due date of your information returns. IRS/IRB will issue a Transmitter Control Code (TCC). The TCC is required on all files and correspondence.
