FIRE All transmitters who file information returns electronically through the Filing Information Returns Electronically (FIRE) system are required to request authorization to file electronically by requesting a Transmitter Control Code (TCC) via the online Information Returns Application for TCC. Submit the request by November 1st of the year before information returns are due and allow 45 days for processing. If your application is approved, a five-character alphanumeric TCC is assigned to your business. To transmit files electronically through FIRE, you must have software, a service provider, or an in-house programmer that will create the file in the proper format per the requirements and record layouts. A scanned or PDF copy will not be accepted. The IRS encourages transmitters who file for multiple payers to submit one application and use the assigned Transmitter Control Code (TCC) for all payers. The purpose of the TCC is to identify the transmitter of the file. You may transmit files for as many companies as you need under the one TCC. Only submit a paper Form 4419 when you have an existing Transmitter Control Code (TCC) issued prior to September 26, 2021 to: Revise current TCC legal business/company name, mailing address or contact information Request an additional TCC via the IR Application for TCC For more information, refer to FIRE or Publication 1220, Specifications for Electronic Filing of Forms 1097, 1098, 1099, 3921, 3922, 5498, and W-2G PDF.
