The practical answer
Before approving Part II, confirm that the form is the authoritative transmittal, reconcile line 20 to all of the employer's 1095-Cs, verify line 21 against the entity timeline, and substantiate every line 22 method selected.
Part II is short, but its entries depend on information held by several teams. The total can span multiple preparers, the group question depends on entity history, and eligibility selections require more than a favorable-looking percentage.
This guide follows the final 2025 Part II instructions and the 2025 Form 1094-C. It is a reviewer checklist for the transmittal's fields, not a general ACA project plan or an electronic filing walkthrough.
Reconcile line 20 to the entire employer's forms
Line 20 concerns the total Forms 1095-C filed by or on behalf of the ALE member. It can include forms transmitted with other batches. The line 20 instructions explain the employer-wide scope.
Obtain the reviewed batch register and reconcile its complete annual records. Keep the line 18 count for this transmittal separate. Investigate records appearing in two provider files and records not assigned to any batch before using the total.
Record whether a later update changes the employer population or merely reallocates records between batches. Moving 20 records from provider A to provider B should not automatically change the employer total; discovering previously omitted required records may.
Review line 21 against dated entity facts
Compare the year-level group response with the reviewed membership timeline. The 2025 line 21 instructions connect a “Yes” response to the monthly group indicator and the list of other members. A current organization chart may omit a relationship that existed earlier in the reporting year.
Use the same approved source for Part II, Part III column (d), and Part IV. Record the actual effective dates behind midyear changes. If the facts are unresolved, send the question to the responsible tax or legal reviewer rather than allowing the form preparer to infer the answer from payroll labels.
The related aggregated-group worksheet can hold the evidence behind the selection without turning Part II into a separate, conflicting entity register.
Substantiate line 22 method selections
For 2025, line 22 provides the Qualifying Offer Method in box A and the 98% Offer Method in box D; boxes B and C are reserved. Eligibility and actual use of the method matter. See the line 22 instructions.
| Selection | Evidence to request | Shortcut to avoid |
|---|---|---|
| A, Qualifying Offer Method | Applicable offer, period, affordability, and method-use analysis | Checking the box solely because a plan was offered |
| D, 98% Offer Method | Reviewed reporting population, offer conditions, applicable months, and method use | Using enrollment percentage as the eligibility test |
| B and C | Current form edition showing reserved status | Copying an obsolete selection from a prior template |
Do not treat a checked box as the evidence for itself. The reviewer should be able to find the underlying analysis and explain how the choice affects the other applicable fields.
Fictional example: a concise annotated Part II
Fictional Pine Strand Company has a reviewed annual reporting population of 200 records split into batches of 150 and 50. Its authoritative transmittal accompanies the first batch. A completed entity review finds group membership during part of the year.
| Field | Reviewed example | Supporting check |
|---|---|---|
| Line 20 | 200 | 150 + 50 across both batches |
| Line 21 | Yes | Approved membership timeline and related fields |
| Line 22 D | Selected | Documented eligibility and actual use |
| Other line 22 selections | Not selected in this example | No unsupported or reserved selections |
For the fictional method review, 196 of 200 records satisfy the reviewed offer conditions throughout the applicable periods: 196 ÷ 200 = 98%. The reviewer also confirms every other requirement. That arithmetic alone, or a 98% enrollment rate, would not establish eligibility.
Approve the dependent fields together
Compare the final Part II to its source register and inspect related fields affected by the selections. For example, actual use of the 98% Offer Method affects the obligation to complete the Part III full-time count. Keep that field review tied to the documented method decision.
Record the output version, actual reviewer, count reconciliation, entity determination, and method evidence. If a supporting population or method changes, revisit the affected selections before release.
Use the downloadable checklist to make approval concrete. Each field should have a source reference and a clear reviewer conclusion. An unexplained checkbox is an open question even when the software accepts it.

Should Part II appear on every 1094-C batch?
The 2025 instructions reserve lines 20 through 22 for the authoritative transmittal. Confirm the designation before reviewing the entries.
Why is line 20 larger than line 18?
Other batches may contain additional forms for the same employer. Reconcile the employer-wide count separately from the forms accompanying this transmittal.
Does a 98% enrollment rate justify box D?
No. The method concerns specified offer conditions and other requirements, not a simple enrollment percentage. Obtain the actual eligibility analysis.
Should we copy last year's boxes?
Use the prior form only as a comparison. Verify the current reporting-year form, actual facts, and methods the employer is using.
What should approval evidence include?
Identify the authoritative output version, batch count bridge, group determination, method analyses, and actual reviewer. Keep unresolved conditions visible.
