ACA Reporting Reminder: Electronic Filing Deadline

Employers subject to the Affordable Care Act (ACA) reporting requirements should prepare to meet the electronic filing deadline for 2025 calendar year reporting. In recent years, the IRS significantly expanded the electronic filing requirement, and most employers are now required to submit their ACA forms electronically. Employers that previously filed paper returns will find that electronic filing is now mandatory.

Employers Subject to ACA Reporting

Applicable Large Employers (ALEs)—generally employers with 50 or more full-time and full-time equivalent employees in the prior calendar year— must report offers of health coverage to the IRS and provide statements to employees using the following forms:

  • Form 1095-C – Provided to full-time employees and filed with the IRS
  • Form 1094-C – Transmittal form summarizing the employer’s reporting

These forms are used by the IRS to determine whether the employer complied with the ACA employer shared responsibility provisions and whether employees may be eligible for premium tax credits through the Marketplace.


Additionally, all employer-sponsors of self-insured health coverage, regardless of size, must report months of enrollment in coverage to the IRS and provide statements to covered individuals using the following forms:

  • Form 1095-B – Provided to covered individuals and filed with the IRS
  • Form 1094-B – Transmittal form summarizing the employer’s reporting

Electronic Filing Requirement

Under IRS regulations finalized in recent years, employers that file 10 or more information returns in aggregate during the year must submit those forms electronically. This threshold applies to the total number of information returns filed with the IRS, including forms such as:

  • Forms W-2
  • Forms 1099
  • ACA reporting forms (Forms 1095-C and 1094-C)

Because the threshold is calculated in aggregate, most employers—including those with relatively small workforces—will now be required to file ACA forms electronically.

Deadline for 2025 Reporting

The deadline to electronically file Forms 1094-B/C and Forms 1095-B/C with the IRS is March 31, 2026. Employers can request an automatic 30-day extension of time to file using Form 8809, which must be submitted to the IRS no later than March 31.

Errors in reporting or failures to file the required forms can result in IRS penalties under Internal Revenue Code §6721 and §6722 for failure to file correct information returns and failure to furnish correct statements to employees.
