If you are an applicable large employer or self-insured employer, the deadline to electronically file ACA information returns with the IRS was midnight ET on June 30, 2016. However, the IRS just announced that the ACA Information Returns (AIR) system will remain up and running after the deadline. In addition, you can still complete required system testing after June 30, 2016.
If any of your transmissions or submissions was rejected by the AIR system, you have 60 days from the date of rejection to submit a replacement and have the rejected submission treated as timely filed. If you submitted and received “Accepted with Errors” messages, you may continue to submit corrections after June 30, 2016.
