Two obligations, often confused
The reporting rules and the penalty rules are separate parts of the statute that happen to use the same data. Understanding which is which makes the whole area considerably less alarming.
§6055 — who actually had coverage
Reports minimum essential coverage, month by month, for every covered individual including dependants. For a fully insured plan the carrier does this. For a self-funded plan it is the employer's job, reported in Part III of Form 1095-C, or on Forms 1094-B and 1095-B by an employer that is not an applicable large employer.
§6056 — what was offered
Applies to applicable large employers regardless of funding. Reports, for each full-time employee and each month, what coverage was offered, what the employee's share of the lowest-cost self-only option was, and which safe harbour applies. Forms 1094-C and 1095-C.
