Form 1094-B, Transmittal of Health Coverage Information Returns, is purely a transmittal form — also known as a cover sheet or summary form. Form 1094-B must be filed to the IRS along with Forms 1095-B. Together, Forms 1094-B and 1095-B are used to report health coverage information to the IRS.

What is Form 1094-B?

Form 1094-B is a very simple form and only requires the filer’s name, contact information, address, and employer identification number (EIN), as well as the total number of Forms 1095-B included with the information return.

Before getting started with this filing, it’s important to be familiar with ACA terms and know what information needs to be reported.

It has the following boxes to report information:

  • Box 1 – Filer’s name
  • Box 2 – Employer identification number (EIN)
  • Box 3 – Name of the employer contact person
  • Box 4 – Contact telephone number
  • Box 5-8 – Employer address information
  • Box 9 – Total number of Forms 1095-B submitted with the transmittal

Why do I need Form 1094-B with Form 1095-B?

As a cover sheet, Form 1094-B contains a summary of the information being filed in Forms 1095-B. Together, these forms provide the IRS and Responsible Individuals with specific coverage information, such as dates of an individual’s or dependent’s coverage.

Form 1095-B, Health Coverage, is used to report information regarding individuals who are covered by minimum essential coverage (MEC) to the IRS. Check out our Essential Guide: Mastering Form 1095-B to get a more in-depth look at this form.

What’s the difference between Form 1094-B and 1094-C?

Both of these are transmittal forms for filings that provide health coverage information. They provide the IRS with some basic information about the filer, but that is where the similarities end.

Form 1094-B is purely a transmittal form that is included with a Form 1095-B filing. As stated above, it is a very simple form with minimal information required.

Form 1094-C is also a transmittal form, but it’s included with a Form 1095-C filing. Generally, employers with 50 or more full-time and full-time equivalent employees (Applicable Large Employers or ALEs) are subject to the employer shared responsibility provisions (ESRP). Employers subject to ESRP that sponsor self-insured health plans, including ICHRA, will generally use Part III of Form 1095-C instead of using Form 1095-B.

Form 1094-C requires the same basic data as 1094-B, such as the filer’s name, address, EIN, and so on. However, it also requires much more detailed information regarding the offer of coverage, monthly head-counts of employees, and information regarding other ALE Members of the Aggregated ALE Group (if applicable). Check out our Essential Guide: Mastering Form 1094-C to get a more in-depth understanding of this form type.

Who needs to file Forms 1094-B and 1095-B with the IRS?

Every entity that provides MEC to an individual during a calendar year must file an information return reporting the coverage. Forms 1094-B and 1095-B are typically completed by insurance companies and other coverage providers, such as small employers. When completing this filing type, filers must submit both Form 1094-B and Forms 1095-B.

Small employers that are not subject to ESRP and sponsor self-insured health plans should use Forms 1094-B and 1095-B to report information regarding covered individuals.

Who needs to file Forms 1094-B and 1095-B with the state?

Along with the federal filing and recipient furnishing requirements, some states have individual requirements as well.

How do I make a correction?

Form 1094-B is purely a transmittal document and does not require correction. You may have errors on your Forms 1095-B, though. That is why it’s important that you take the time to review the information you are reporting on your forms for accuracy before distributing and filing. This will minimize the risk of common errors which may result in your business incurring penalties and fines.

Even with careful reviewing, mistakes can happen! If your filing has errors, you can easily make corrections to your Forms 1095-B.

  • If you submitted your original filing electronically, then you should edit your filing accordingly with the original vendor.
  • If you submitted your original filing via mail, then you should complete a new form and include the updated information.
    •      Once this has been completed, simply check the ‘Corrected’ box at the top of the form. Always include a new transmittal Form 1094-B when mailing in corrections to the IRS.

Before you can consider your correction complete, an updated copy of the form must be provided to the recipient as well. This ensures that all parties have updated information.


Once you have submitted your Forms 1094-B and 1095-B to the IRS, either electronically or via mail, and have received your “Accepted” status, then you have met all of the IRS requirements for these forms.

It’s extremely important to ensure that you’re submitting the correct type of ACA filing. Learn more about the differences between Form 1094-B and Form 1094-C using the link below!
