How do I correct a business name control code mismatch on my ACA e-filing forms?

If you receive an email from Zenefits that your ACA forms were rejected because of a name control code mismatch, you should:

  1. Log in to Zenefits and click on the ACA Compliance app.
  2. Click Filing in the orange navigation bar at the top.
  3. Click Fix Errors.
  4. Double check to make sure your Employer Identification Number (EIN) is correct on your e-filing.
  5. Review the rules and examples for valid business name control codes and confirm that the correct name control code was included in your e-filing. Click Edit to fix any incorrect control codes.
  6. If you can't determine the correct codes on your own, call the IRS Business Line at (800)829-4933 (choose option 1) for assistance.

The IRS Error Code for a mismatched business name control code is AIREX126.
