Confirm the ALE member and reporting population
Use the employer's reviewed ALE determination and legal-entity map. ALE status generally depends on the prior year's average full-time employees plus full-time equivalents, with related-employer and other rules. The IRS ALE guidance explains that determination.
The 2025 C-series instructions generally require reporting for each employee who was full-time for any month, whether or not that employee enrolled. Self-insured coverage can create additional reporting work. Do not build the filing population solely from the active enrolled roster at year-end.
Collect a source package that can be reconciled
Identify the employer master record, employee history, approved offers, required-contribution data and applicable enrollment source. Give every delivery a year, effective-date definition and stable internal record key. List absent files and unresolved interpretations before starting form generation.
Combine same-employer records from multiple divisions into the appropriate annual employee record. Keep legitimate relationships with separate ALE members distinct. A duplicate name is a review signal; it does not by itself determine which source row should be removed.
Reconcile a fictional filing population
Fictional Oak Harbor expects 160 annual employee-employer records. Its generated draft contains 162 records. Review finds three repeated source records and one omitted approved employee. The repair is 162 - 3 + 1 = 160.
Changing a transmittal count to 160 would not repair the membership defect. The preparer fixes the generated population, repeats the comparison and then reconciles the accompanying count. The reviewer samples a corrected overlap and the restored employee to verify that each has complete annual history.
Approve the version and define the filing handoff
The release packet should identify the final data and form version, population reconciliation, field-review results, unresolved exceptions and actual approval. Match the 1094-C structure to the employer's complete batch plan under the authoritative-transmittal rules.
Electronic ACA returns go through IRS AIR. Agree which transmitter will deliver the approved records, retrieve the acknowledgment and return error details. Keep furnishing work separate, including any alternative-furnishing decision under Notice 2025-15. An approved draft does not establish either agency acceptance or statement delivery.
Prepare a correction from the actual original
Preserve the original filed version and outcome before assembling a changed record. Explain the affected employee, months, old values, supported new values and unchanged information. The correction instructions require the applicable complete corrected record; rejected files and accepted records needing changes follow different technical handling.
The preparer supplies source-backed changes. The transmitter selects the technical action using agency history. Track any corrected employee statement as its own deliverable.

Questions from reporting teams
Should we exclude employees who declined coverage?
No automatic exclusion follows from a waiver. Apply the reporting rules to the reviewed employment and offer history, including employees who were full-time for a relevant month.
Does ten mean ten 1095-C forms alone?
The general electronic-filing threshold uses 10 or more specified information returns in aggregate. Review the complete applicable return inventory and any approved waiver.
Can our provider approve the employer's source facts?
Agree who owns each decision. A provider can assist preparation, but the release should identify the actual evidence and authorized employer review for the reporting facts.
When can preparation close?
Close the identified preparation scope when the approved version and handoff are complete. Keep transmission outcomes, furnishing and unresolved correction work visible as separate downstream responsibilities.
