Affordable Care Act Information Returns (AIR) Program

Affordable Care Act (ACA) information returns and transmittals are electronically filed through the ACA Information Return system, also known as AIR. 

Program Overview

Under the Affordable Care Act (ACA), insurance companies, self-insured companies, and large businesses and businesses that provide health insurance to their employees must submit information returns to the IRS reporting on individual’s health insurance coverage.  

Other non-ACA information returns, such as Forms 1099, can be electronically transmitted through the Filing Information Returns Electronically system, also known as FIRE.  The AIR system has different requirements than FIRE.You must follow the AIR procedures explained on this page even if you have previously used FIRE.

ACA information returns include:  

  • Form 1094-B, Transmittal of Health Coverage Information Returns
  • Form 1095-B, Health Coverage
  • Form 1094-C, Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Returns
  • Form 1095-C, Employer-Provided Health Insurance Offer and Coverage

Anyone required to file 250 or more information returns, must file them electronically. This requirement applies separately for each type of return and separately to each type of corrected return. All filers are encouraged to electronically file even if you have less than 250 returns.


Here’s what you need to know to get started with AIR:

In general, if you are a software developer, transmitter, or issuer required to file 250 or more returns or want to file electronically, you will need to register with e-Services and get a Transmitter Control Code (TCC). 

  • Software Developer: An organization writing either origination or transmission software according to IRS specifications.
  • Transmitter: A third-party sending the electronic information returns data directly to IRS on behalf of any business.
    • Note: If you are transmitting returns for your own company in addition to transmitting returns on behalf of another business, you do not need both the Transmitter and Issuer role. You can file all returns as a Transmitter.
  • Issuer: A business filing their own ACA Information Returns
    • Note: If you are an issuer using a third party to transmit your returns (that is, you are not transmitting information returns directly to the IRS), you should not apply for a TCC and do not need to follow the steps below.

Complete the steps below if you are a:  

  • Software developer who will develop software for use in creating electronic files for ACA Information Returns.
  • Transmitter who will transmit information returns to the IRS.
  • Issuer who will transmit information returns directly to the IRS.

Step 1: Register to use IRS e-Services Tools

Before using any IRS e-Services tools, all responsible officials and contacts in the business or organization must create an e-services account using a rigorous two-factor authentication process called Secure Access. Two-factor authentication means you must have your credentials (username and password) plus a security code sent to your mobile phone or generated by your IRS2Go app each time you log in. Responsible Officials and Contacts must create an account using the Secure Access two-factor authentication process before you can apply for your TCC.

Before starting the identity proofing process, review Secure Access: How to Register for Certain Online Self-Help Tools.

Step 2: Apply for your Information Return Transmitter Control Code - TCC

Software developers, transmitters, and issuers must have a TCC to electronically file AIR Forms 1094/1095-B and 1094/1095-C. After you create a Secure Access account (see Step 1) you will have access to the ACA Application for TCC. 

  1. Complete the ACA Application for TCC
  2. The Responsible Officials must sign the terms of agreement with the PIN created during the registration process.
  3. When the application is in completed status, the Transmitter Control Code(s) will be visible online and will be mailed to you via U.S. Postal mail.

Each role selected on the application - software developer, transmitter, and issuer - results in a separate TCC.

  • When conducting software testing with the IRS, use the software developer TCC
  • If you are transmitting information returns, use the transmitter or issuer TCC

Step 3: Test Communication with AIR System

Software developers, transmitters, and issuers must pass all applicable test scenarios. This will help ensure you can communicate with the IRS before you submit information returns through the AIR system.

  • Software Developers are required to annually pass Affordable Care Act Assurance Testing System (AATS) testing to transmit information returns to the IRS. You will need a new Software ID for each tax year and each ACA Information Return package they support.
  • Transmitters and Issuers must use approved software to perform the communications test. You are only required to successfully complete the communication test once.

Information for Tax Year 2017:

  • AIR TCCs for Transmitters and Issuers that are in Production status will remain in Production status. No additional testing is needed for Tax Year 2017.
  • Software Developers need to update their ACA Application for TCC each year to obtain a new software identification number for the new tax year
  • Software Developers who passed testing for Tax Year 2015 and/or Tax Year 2016 do not need to test for Tax Year 2017. Software IDs are scheduled to move to Production one week from the date the software IDs are assigned.
    • When the 2017 software packages are added, Responsible Officials will need to re-sign the ACA Application for TCC.
    • AIR Transmissions (both live and test) will reject If the ACA Application for TCC is not signed and in Completed status.
    • Allow 48 hours before transmitting to Production after passing any required testing.

Publication 5164, Test Package for Electronic Filers of Affordable Care Act (ACA) Information Returns (AIR), contains general and program specific testing information for use with AATS.

Affordable Care Act Information Returns (AIR) Assurance Testing System (AATS) page for testing information, including test scenarios.

Step 4: Electronically Filing through AIR

Transmissions to AIR must be comprised of only one type of ACA information return and you must include the appropriate transmittal form. For example, a transmission must only contain:

  • Forms 1095-B and Form 1094-B or 
  • Forms 1095-C and Form 1094-C

The form types cannot be combined. Additionally, original and corrected forms cannot be combined in the same transmission file.  

AIR will process each submission and provide a status with detailed acknowledgement for the transmitter. Issuers should retain a copy of information returns for at least three years from the reporting due date.
