Step-by-Step: How to File Form 1094 & 1095 Online
Steps to Amend ACA Forms (1095-C/1094-C):
Identify Errors: Determine if the error is in the employee's name, SSN, or the employer’s EIN, requiring a new Form 1095-C.
Prepare Corrected Forms:
Mark "Corrected": Check the "CORRECTED" checkbox at the top of the Form 1095-C.
Complete Form 1095-C: Create a new Form 1095-C with the corrected data for the employee.
Create Form 1094-C: Prepare a new, non-authoritative Form 1094-C transmittal, or an authoritative one if required, to submit with the corrected 1095-C.
File with the IRS: Submit the corrected forms to the IRS. If submitting electronically, mark the transmission as "Corrected" in the AIR system.
Notify Employees: Distribute the corrected Form 1095-C to the affected employee(s) immediately.

Key Considerations:
Authoritative Transmittal: If the original 1095-C was submitted with an authoritative transmittal (1094-C), the correction should be submitted with a new authoritative transmittal.
Deadlines: Ensure corrections are made as soon as possible after discovering the error to avoid penalties.
Third-Party Vendors: Services such as ACAwise or TaxBandits can assist with the correction and re-transmission process
