By: Krista J. Maschinot, Esq. If you are an applicable large employer (ALE), the Internal Revenue Service (IRS) could possibly be sending a Letter 226J notice your way. Will you be ready to respond accurately within 30 days of receipt if needed? We discussed in a recent blog post that IRS enforcement of the Employer Shared Responsibility Provision of the Affordable Care Act (ACA) is very real and ALEs should be prepared as such. There are two types of ESRP penalties that the IRS will assess based upon the information the ALE provided on Forms 1094-C and 1095-C: §4980H(A) – Assessed when an employer fails to offer minimum essential coverage to enough of its full time employees §4980H(B) – Assessed when an employee enrolls in the Marketplace and qualifies for the premium tax credit because the employer failed to offer affordable coverage We recommend comprehensively reading and reviewing the information provided in the Letter 226J as to the reasoning for ESRP penalties and ensuring that this matches up with your internal documentation. This review is particularly significant because it will help you determine whether you have made an administrative/filing oversight or if there are larger compliance issues to deal with. There are common mistakes to be aware of based on how Forms 1094-C and 1095-C were filled out that could trigger a Letter 226J. An ALE could, for instance, forget to check the “Section 4980H Transition Relief” box (Box C of line 22) on Form 1094-C . It may also fail to correctly code Line 14 of Form 1095-C regarding offer of coverage based on months offered coverage, as opposed to months of actual coverage. These types of errors are easy enough to make, but it is important to identify that they have been made prior to responding to the IRS. The monetary penalties will be assessed much differently based on filing mistake rather than actual ESRP non-compliance.
