ACA 2026: Updated 1095-C Penalties & Reporting Requirements

Employers Ensuring ACA Compliance

If your business is an Applicable Large Employer (ALE), it’s time to prepare for updated Affordable Care Act (ACA) reporting rules for 2026. The IRS has released new penalty structures and clarified some of the reporting processes tied to Form 1095-C, and failing to stay compliant could cost you thousands per employee.

This guide provides everything you need to know about 1095-C updates, new fines, and the steps to take before Q1 2026.

Who Needs to File 1095-C?

Employers classified as ALEs (those with 50 or more full-time equivalent employees) are required to offer Minimum Essential Coverage (MEC) that is affordable and provides minimum value. They must also report this coverage annually using:

  • Form 1094-C (transmittal form)
  • Form 1095-C (individual offer of coverage form)

These forms help the IRS determine:

  • Whether the employer met ACA requirements
  • Whether employees are eligible for marketplace subsidies
  • Whether penalties apply

Key Changes to 1095-C Reporting in 2026

1. Penalty Amounts Have Increased

The IRS has raised the penalties for failure to file or furnish 1095-C forms:

  • Failure to file or furnish: $310 per form (up from $290 in 2024)
  • Intentional disregard: $630 per form

For a 200-employee company, this could mean:

$310 x 200 = $62,000 in potential penalties

And that’s just for one year of missing reports or furnishing late.

2. Tighter Deadlines

  • Recipient deadline (employee copy): Now January 31, 2026 (unchanged but being more strictly enforced)
  • IRS deadline (paper filing): February 28, 2026
  • IRS deadline (electronic filing): March 31, 2026

Important: If you have 10 or more forms, you must file electronically.

3. Electronic Filing System Overhaul

The IRS upgraded its Affordable Care Act Information Returns (AIR) system to improve validation, but it now:

  • Flags errors faster
  • Rejects inconsistent codes (Line 14/16 mismatches)
  • Requires updated user access for transmitters

If your vendor hasn’t updated their integration, rejections will increase.

4. Clarified Reporting for Conditional Offers

New IRS guidance clarifies how to report conditional spousal offers and COBRA offers.

  • Use Code 1J or 1K properly on Line 14
  • For COBRA offers due to termination, do not report the offer unless the employee was enrolled during employment

This is a major source of errors and potential fines.

Real-World Example: A Costly Oversight

A California tech firm with 125 employees used a payroll vendor that failed to file 1095-Cs for two years. They assumed the vendor was handling it.

Result:

  • $310 x 125 employees x 2 years = $77,500 in penalties
  • Plus legal fees to appeal, and hours of HR remediation

How to Stay Compliant in 2026

✅ Step 1: Confirm ALE Status Monthly

Track your full-time equivalents every month to avoid last-minute surprises.

✅ Step 2: Review Coverage Offers & Affordability

Make sure your group health plans meet the 2026 affordability threshold. For 2026, the employee contribution can’t exceed 8.39% of their household income (or safe harbor proxy).

✅ Step 3: Use the Correct Codes

1095-C Line 14 and 16 codes are not intuitive. Ensure you:

  • Use Code 1A only for full-year qualifying offers
  • Don’t use Code 2C unless the employee actually enrolled

✅ Step 4: Vet Your Vendor or Platform

Ask your ACA filing vendor:

  • Are you updated for the 2026 IRS AIR specs?
  • Do you offer error monitoring and real-time rejections?
  • Can I access my submission proof and acknowledgments?

✅ Step 5: Keep Records for 3–4 Years

IRS audits can go back several years. Keep:

  • Proof of offers made
  • Waivers declined
  • Affordability calculations

Frequently Asked Questions

The employer is ultimately responsible. Even if a vendor prepares or files the 1094-C and 1095-C forms, the IRS holds the employer accountable for accuracy and compliance. You should review all reports before submission, confirm that employee data and coverage codes are correct, and keep records of your review.

The IRS may impose fines for inaccurate or missing filings, with penalties increasing based on the number of employees affected. Staying accurate with reporting minimizes financial risk.

Most employers keep ACA reporting records for at least three to four years after the filing date. Maintaining these records for several years provides protection if the IRS reviews a company’s compliance or if employees question the information reported on their forms. These records should include payroll data, employee eligibility calculations, copies of filed forms, and health plan enrollment details. Organized documentation makes it easier to respond to any requests for verification.

Common mistakes include incorrect coverage codes, missing employee data, and mismatched payroll records. Many employers also misclassify affordability or forget to update monthly eligibility details. These errors can lead to IRS rejection or penalties, even if the coverage itself is compliant.
