How to participate

New users are required to submit Form 4419, Application for Filing Information Returns Electronically , to IRS/ECC-MTB at least 15 days before the due date of the return(s) for current year processing. Form 4419 may be faxed to IRS/ECC-MTB at 877-477-0572 or mailed to: Internal Revenue Service
Enterprise Computing Center - MTB (ECC-MTB)
Information Reporting Program
230 Murall Drive
Kearneysville, WV 25430

Faxing is fast. Add a letter to the fax with all of your contact information, from address, phone, to e-mail and ask that someone from the IRS call or e-mail you with the TCC number.

Upon approval, a five-character alpha/numeric Transmitter Control Code (TCC) will be assigned. IRS/ECC0MTB uses the TCC to identify payers/transmitters and to track their files through the processing system.

Once a transmitter is approved to file electronically, it is not necessary to reapply unless the payer has discontinued filing electronically for two consecutive years. Payers who know that the assigned TCC will no longer be used, are requested to notify IRS/ECC-MTB so these numbers may be reassigned.

How many TCC number's do I need?
A single Form 4419 should be filed no matter how many types of returns the transmitter will be submitting electronically. For example, if the transmitter plans to file Forms 1099-INT, one Form 4419 should be submitted to attain a TCC number. If the transmitter also wants to file Forms 1098, 1099, 3921, 3922, 5498, 8935 and/or W-2G, the transmitter can use that same TCC number and does not have to submit a new Form 4419 to attain another TCC number.

An additional Form 4419 (and separate TCC) is required and for filing:

Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding and
Form 8027, Employer's Annual Information Return of Tip Income and Allocated Tips.
Form 8955-SSA, Annual Registration Statement Identifying Separated Participants with Deferred Vested Benefits.


If you are electronically filing 1042-S, 8027 and/or 8955-SSA, you need to submit Form 4419 again and apply for a separate TCC for 1042-S, 8027 and 8955-SSA.
