Form 1095-C is an employer reporting task. This resource helps HR, payroll and benefits teams determine which employees require a return, prepare the correct monthly information, and review the output before filing.
Determine the employer's filing population
An applicable large employer member generally files Form 1095-C for each employee who was full-time for any month of the calendar year. ALE status generally considers the prior-year average of full-time employees and full-time equivalents, including applicable aggregation rules. A small subsidiary can still be an ALE member because of its group relationship.
An ALE member sponsoring self-insured coverage also reviews enrolled employees who were never full-time. Keep those population rules separate from a year-end enrollment filter. Employees who waive coverage can still require offer reporting. The 2025 employer instructions describe the specific populations, exceptions and nonemployee reporting options.
Prepare the actual Form 1095-C fields
| Form area | Reporting task | Source to review |
|---|---|---|
| Part I | Identify the employee and ALE member | Approved HR identity records and employer EIN details |
| Line 14 | Report the applicable monthly offer | Plan terms, eligibility and offer dates |
| Line 15 | Report the required contribution when applicable | Correct offer-rate schedule and effective dates |
| Line 16 | Apply a supported status or relief code | Enrollment, employment and applicable safe-harbor evidence |
| Part III | Report applicable self-insured covered individuals | Administrator enrollment and identifying records |
Part II does not contain a separate full-time checkbox. Line 15 is not automatically the employee's elected-plan payroll deduction, and a waiver alone does not supply a line 16 code. Review the actual field instructions before filling a default value.
Separate offers from self-insured enrollment
For insured group-plan coverage, the ALE member prepares its applicable offer reporting and does not complete Part III for that insured enrollment. For applicable self-insured coverage, Part III identifies enrolled people and their coverage months. An offer of family coverage is not evidence that every family member enrolled.
Employers with mixed funding arrangements, HRAs, employee spouses or nonemployee coverage should record the applicable treatment before importing the population. Use source dates for each covered person and do not apply one monthly rule indiscriminately across offer codes, line 16 and Part III.
Review and file under the correct employer identity
Combine same-ALE-member division records into the appropriate single annual employee return. Preserve separate ALE-member EINs and review employees who worked for more than one member. Reconcile the approved employee population with the related Form 1094-C structure.
For calendar year 2025, the employer instructions specify March 2, 2026 for paper filing and March 31, 2026 for electronic filing. Employers meeting the aggregate electronic-filing threshold generally must e-file, subject to applicable waivers. ACA electronic returns use AIR, with its applicable schemas and business rules. Retain the acknowledgment and resolve reported errors; generating a statement is not filing.
Assign furnishing and correction work
Plan the employee-statement process separately from IRS filing. The regular 2025 furnishing date is March 2, 2026. The alternative manner of furnishing permits a compliant notice-and-request approach when its requirements are met, including timely requested copies. It does not eliminate the agency filing obligation.
Give employees a clear employer contact for factual questions. Verify disputed fields against the business records, establish the original filing status and use the applicable correction procedure. Track any required agency change and corrected-statement furnishing separately.
Business filing FAQs
Do we file for full-time employees who declined coverage?
Generally yes when the ALE-member reporting rules apply. Review them in the employer population and report the actual offer and applicable status. Do not omit them simply because no premiums were deducted.
Can line 15 come from the employee's family-plan deduction?
Not automatically. When required, line 15 uses the contribution determined under the applicable offer rules. Review the lowest-cost qualifying self-only option and the relevant form instructions.
Does the carrier file the employer's 1095-C?
A carrier's coverage reporting does not replace the ALE member's employer offer reporting. Confirm the actual service assignment if another organization prepares or transmits the employer's records.
Is a corrected PDF enough after we filed?
No. Determine whether the agency record also needs correction, follow the relevant procedure and document the employee furnishing outcome. Preserve the original record and approved change.
