Applicable Large Employers (ALEs) must understand ACA rules in 2025 to avoid costly penalties. Rules now include new thresholds and reporting requirements. Staying compliant remains critical.


What Are the “A” and “B” Penalties?

A‑Penalty (Section 4980H(a))
ALEs face this penalty if they don’t offer Minimum Essential Coverage (MEC) to at least 95% of full‑time employees and one receives a subsidy.
For 2025, the penalty totals $2,900 per full‑time employee (after the first 30).

How Employers Can Stay Compliant

1. Verify ALE Status
Ensure you are classified correctly based on the average of 50 full-time equivalents or more.

2. Offer MEC to 95%+ Full‑Time Employees
Or risk the A‑Penalty if a subsidized exchange participant exists.

3. Confirm Affordability & Minimum Value
Plans must meet IRS affordability safe harbors and cover at least 60% of plan costs.

4. File Accurate IRS Forms
Submit Forms 1094‑C and 1095‑C correctly and on time to avoid late-filing fines.

5. Monitor Plan Design Regularly
Adjust premiums or coverage annually to meet evolving affordability criteria.
