Form 1095-C is an annual federal information return that an applicable large employer (ALE) uses to report health coverage it offered to certain employees and, when required, coverage under a self-insured health plan. An employer is generally an ALE if it averaged at least 50 full-time employees, including full-time equivalent employees, during the preceding calendar year. The form reports information by month, so entries can change when an employee’s work or coverage circumstances change during the year. Employers file the information with the IRS and provide statements to employees under the applicable furnishing rules. Employees can use the form to review what the employer reported, but they generally do not attach it to a federal income tax return. Form 1095-C describes an offer or enrollment for reporting purposes; it does not by itself prove that an employee enrolled in the offered coverage. It is useful to understand the distinction between an offer of coverage and actual enrollment when reviewing the form or asking an employer to correct it.

Who Receives a Form 1095-C?
An ALE generally files a Form 1095-C for each person who was its full-time employee for at least one month of the calendar year. For this purpose, the IRS generally defines full-time status as an average of at least 30 hours of service per week or 130 hours during a calendar month. The employer’s ALE status is determined separately for each year using workforce information from the preceding year. Part-time employees may also receive a form if they enrolled in coverage under the ALE’s self-insured health plan. As a result, receiving a form does not always mean that the recipient was a full-time employee for the entire year.
Reaching the 50-person threshold is not simply a matter of counting everyone on the current payroll. Full-time equivalent employees are included when the employer determines ALE status, and special rules can affect the calculation. The IRS explains the threshold and its exceptions in its guidance on how to determine applicable large employer status. An employer that falls below the threshold is generally not subject to the ACA employer information-reporting requirement for that year. Because the calculation uses prior-year workforce information, an employer’s status can change from one reporting year to the next.
What Information Does the Form Contain?
Part I identifies the employee and the ALE member reporting the information. It includes identifying details such as names, addresses and taxpayer identification information. Part II describes the employer’s offer of coverage for each month. Codes in this part indicate details such as whether coverage was offered and whether the employee met certain reporting conditions. The form may also show the employee’s required contribution for the lowest-cost self-only coverage that meets minimum value, when applicable. These entries are used for reporting purposes and may require reference to the IRS instructions to interpret correctly.
Part III is completed when the ALE member sponsors a self-insured plan and must report the individuals covered under it. It can identify the employee and covered family members along with the months of coverage. A code in Part II does not necessarily mean the employee enrolled. It may describe an offer rather than actual coverage. Since the form uses monthly entries, a change in employment, eligibility or an offer during the year can produce different codes from one month to another. The IRS instructions for Forms 1094-C and 1095-C explain the codes and how employers use them. Comparing those monthly entries with enrollment records can help clarify what the form reports.
How Do Employers Use and File the Form?
Employers use Form 1095-C to report information required under the ACA’s employer information-reporting rules. The IRS can use that information when administering the employer shared responsibility provisions. It can also help determine whether an employee may qualify for a premium tax credit. A form reports information; it does not, on its own, establish that an employer owes a payment or that an employee qualifies for a credit. Those determinations depend on the applicable rules and the relevant facts.
The employer files Forms 1095-C with the IRS and sends the related transmittal, Form 1094-C. For reporting year 2025, the IRS instructions set the filing deadline at March 2, 2026, for paper returns and March 31, 2026, for electronic returns. Filing and delivery requirements can change by reporting year, so employers should check the instructions for the specific year at issue. They should also ensure that monthly offer and coverage information is supported by accurate records.
For statements covering 2025, an employer may use an IRS-authorized alternative to automatically sending every employee a paper statement. It must provide a clear and accessible notice explaining how to request a copy, then furnish a requested copy by the applicable deadline. Rules for electronic delivery and consent are separate. Employees should follow the employer’s instructions for requesting or accessing a statement. Employers should confirm which furnishing rules apply for the reporting year rather than assume that a process used previously remains unchanged.
What Should an Employee Check?
Check that the identifying information is correct and that the form covers the right calendar year. Review the monthly entries to see whether the reported offer and coverage status match your understanding. If Part III is present, check the covered individuals and the months listed there. An offer code is not a confirmation of enrollment, so compare the reported offer with plan enrollment records if you need to verify whether you had coverage. A form may show different information across months because eligibility or an offer changed during the year.
Contact the employer or its designated benefits or payroll contact if information appears wrong or is missing. The employer can review the underlying records and determine whether it needs to issue a corrected form. Keep the form with your tax records. The IRS says taxpayers do not need to wait for a Form 1095-C to file a federal return and generally should not attach the form to that return. See the IRS’s answers about health coverage forms for individuals for more on how the document relates to filing a return. If you contact the employer, identify the month or entry you are asking about so it can review the issue efficiently.
How Is a 1095-C Different from Other Health Coverage Forms?
Form 1095-C is the employer reporting form used by ALE members. Form 1094-C is the employer’s transmittal and summary to the IRS. They work together in the employer’s reporting process, but they serve different purposes. Form 1095-C contains employee-specific information, while Form 1094-C summarizes the employer’s filing. Employees typically review the 1095-C statement rather than the transmittal form.
Form 1095-A comes from a Health Insurance Marketplace and reports Marketplace coverage. Form 1095-B is generally used by insurers and certain other coverage providers to report minimum essential coverage. The form a person receives depends on the source of coverage and the reporting rules that apply. Receiving a 1095-C does not necessarily mean a person also received a 1095-A or 1095-B. These forms are not interchangeable because they report different coverage information and come from different reporting entities. The IRS overview of Form 1095-C describes its employer-reporting purpose. If you receive more than one type of form, review each according to the coverage it reports.
Why Can Contingent Workforce Programs Need to Account for It?
In a contingent workforce program, the organization directing a project and the entity employing and paying a worker may not be the same. That distinction can matter when determining which employer has responsibility for benefit administration and ACA reporting. A client organization should not assume that a worker supplied by a staffing partner will appear on the client’s Form 1095-C, or that the staffing partner’s form will reflect the client’s own reporting obligations. The employer’s legal relationship with the worker and the applicable ACA rules determine the reporting responsibility. The reporting form itself does not resolve questions about which entity is the employer.
Programs that use contingent workers can make this operationally clearer by documenting which party handles payroll, benefits administration and the collection of employment and coverage records. This is especially useful when assignments start or end during the year or workers move between arrangements. Staffing and workforce-management processes may involve coordination of those records, but the existence of a program or vendor relationship does not by itself settle who is the reporting employer. When responsibility is uncertain, the relevant parties should review the facts and consult qualified tax or benefits counsel. Clear records can help the responsible employer report monthly employment and coverage information accurately.
