Form 1094-C is the federal Affordable Care Act form that an applicable large employer member uses to summarize its health coverage reporting and transmit Forms 1095-C to the IRS. An employer generally qualifies as an applicable large employer (ALE) if it averaged at least 50 full-time employees, including full-time equivalents, during the prior calendar year. Certain related employers are combined when the IRS determines whether the group meets that threshold. If the group qualifies, each ALE member generally reports separately for its own employees. Form 1094-C is an employer-level filing rather than an individual employee’s coverage statement. It accompanies and summarizes employee-level reporting but does not replace the Forms 1095-C. The form helps the IRS connect an ALE member’s summary information with the employee forms it submits.

Who Files Form 1094-C?
An employer that is an ALE or an ALE member generally has Form 1094-C reporting responsibilities. ALE status is determined each year using workforce information from the preceding calendar year. The calculation combines full-time employees with full-time equivalents derived from the hours of non-full-time employees. The IRS explanation of how to determine ALE status describes the calculation and the related-employer rules.
Some businesses with common ownership or other qualifying relationships are aggregated to determine whether the group reaches the threshold. If it does, each separate employer in the group is generally an ALE member. A member may therefore have filing responsibilities even if its own workforce is below the threshold. Group aggregation determines ALE status, but it does not mean that one member’s Form 1094-C automatically reports for the others. Each member generally files separately for its own employees.
Employers need to identify the correct legal entity and account for the applicable workforce when determining who files. The fact that businesses share ownership or administrative services does not by itself make one entity’s filing cover the others. The employer should apply the IRS aggregation rules to the relevant reporting year and confirm which entity is responsible for its forms.
The federal filing requirement is distinct from state or local health coverage requirements. Those rules may impose separate obligations depending on where an employer operates. Filing Form 1094-C does not by itself establish compliance with every applicable reporting rule. Employers with operations in multiple jurisdictions may need to review each jurisdiction’s requirements separately.
How Does It Differ from Form 1095-C?
The forms work together but serve different purposes. Form 1094-C provides the IRS with a summary for the ALE member and transmits the member’s Forms 1095-C. Form 1095-C reports information about an individual employee, including information about coverage offers. It also reports enrollment details when the employer has a self-insured plan and the reporting rules call for them.
Employees generally look to Form 1095-C for their own reported coverage information. Form 1094-C is not an employee’s personal coverage statement. Employers commonly treat both forms as part of their year-end tax forms process, but these forms concern health coverage reporting rather than wages or tax withholding.
The distinction matters when an employer reviews or corrects a filing. Form 1094-C carries employer-level information, while Form 1095-C contains information about a particular employee. A mistake in one form does not necessarily mean the other form is incorrect. Employers should identify where the inaccurate information appears and follow the relevant correction instructions.
Self-insured coverage does not by itself make an employer an ALE. A non-ALE employer that sponsors a self-insured plan may have separate reporting responsibilities as a coverage provider. That is distinct from an ALE member’s Form 1094-C filing obligation. The IRS overview of employer shared responsibility provisions explains how ALE reporting relates to coverage obligations.
What Information Does the Form Contain?
Form 1094-C identifies the ALE member that is filing and includes contact information. It indicates whether the member belonged to an aggregated ALE group and provides group-member information where required. It also reports the number of Forms 1095-C being transmitted and includes monthly employer-level information requested by the form.
The form has sections for annual summary information and for monthly details. Those details can include information about coverage offers and whether certain reporting conditions or relief provisions apply. The form’s codes and fields have specific meanings, so the employer should not select them based only on an informal interpretation. The instructions for the reporting year explain how to complete the fields.
Employers should compare the form with their underlying records and related employee forms. Relevant records may include information about employee status and coverage offers. A consistent review can help identify an incorrect employee count or a mismatch between the summary and the forms being transmitted. The specific information requested may vary by reporting year.
If an ALE member submits multiple Forms 1094-C, one may need to be identified as the “Authoritative Transmittal.” This filing provides the member’s authoritative annual summary. Submitting additional transmittals does not remove the need to follow the instructions for identifying the authoritative form. The member’s Tax Identification Number and legal-entity details should also be checked for accuracy.
How Does Filing Work?
For each reporting year, the ALE member identifies the applicable employees and prepares the required Forms 1095-C. It then completes Form 1094-C with the member’s identifying information and summary data. The member submits the transmittal with the employee forms to the IRS. Employers should reconcile the forms against records of employee status and coverage offers before filing.
Filing methods and deadlines depend on the reporting year. The IRS’s 2025 instructions state that Forms 1094-C and 1095-C for calendar year 2025 were due by March 2, 2026, for paper filing. The electronic filing deadline was March 31, 2026. These dates have passed and should not be assumed to apply to another reporting year. Check the IRS instructions for the applicable tax year for current filing requirements and any available extension process.
Before submission, the member should verify that its reported count of Forms 1095-C matches the forms being transmitted. It should also check that the forms identify the appropriate ALE member and contain consistent information. A review process can help catch missing forms or data that does not agree with payroll and benefits records.
If an error is discovered, consult the correction instructions to determine whether the issue affects Form 1094-C, one or more employee forms, or both. The appropriate correction depends on what information is wrong and where it appears. Accurate records help the employer identify discrepancies and prepare corrections. Employers should use the instructions that apply to the reporting year rather than relying on a prior year’s process.
What Should Contingent Workforce Programs Consider?
For organizations using a contingent workforce, the relevant question is which employer is responsible for the worker and the related ACA reporting. A worker’s presence at a client site does not alone determine who employs the worker or who must assess full-time status and report coverage offers. The answer depends on the actual employment relationship and applicable rules.
Program records may need to distinguish a client’s employees from people employed by a staffing or other service provider. A person’s label in a contract or workforce system does not by itself settle employment status. Clear processes help the responsible employer maintain information about the employee and any coverage offer. They also help separate the client’s records from those of a contingent worker employed by another entity.
For example, a client may receive services from workers employed by a staffing provider. The client’s records should make clear which entity employs each worker and which entity maintains the relevant benefits and employment information. The responsible entity can then assess its obligations using the applicable rules and records. These arrangements should not be treated as automatically assigning ACA reporting duties to the client or the provider.
Where TCWGlobal supports contingent workforce programs or related payroll processes, the practical connection is coordination of workforce information and responsibility boundaries. Organizations should establish which employer maintains the records needed for ACA status determinations and which entity prepares required forms. Those responsibilities should reflect the facts of the work arrangement. Appropriate tax or legal guidance can help resolve unclear situations.
