Resolving IRS Notice AIRTN500: Missing Transmitter Control Code on 1094-C

Resolving IRS Notice AIRTN500 Missing Transmitter Control Code on 1094-CIRS Notice AIRTN500 is issued when the Transmitter Control Code (TCC) is missing from Form 1094-C submissions. The TCC is essential for electronic filing, serving as a unique identifier for the transmitter of the tax information to the IRS.

Importance of the Transmitter Control Code

The Transmitter Control Code (TCC) is critical because it:

  • Ensures that the electronic submission is recognized and processed by the IRS’s e-filing system.
  • Helps maintain the security and tracking of the transmitted data.

Consequences of a Missing TCC

Submitting Form 1094-C without a TCC can lead to:

  • Rejection of the form by the IRS’s electronic filing system.
  • Delays in processing and potential penalties for late or incorrect submissions.

How to Address a Missing TCC Issue

To resolve a notice related to a missing TCC:

  • Obtain a TCC by applying through the IRS e-Services – Application for TCC.
  • Update the Form 1094-C submission with the correct TCC and resubmit electronically as soon as possible.
  • Verify the TCC is correctly entered in future submissions to avoid similar issues.

Preventing TCC Errors

To prevent future issues with missing TCC on submissions:

  • Ensure the TCC is securely stored and readily available for use during the submission process.
  • Implement a checklist for electronic submissions to verify that all required codes and identifiers, like the TCC, are included before filing.
  • Consider using compliance software such as ACA-Track, which can automate and safeguard the inclusion of necessary identifiers in all electronic filings.
