1095-B and 1094-B

Form 1095-B is used to meet the Section 6055 reporting requirement to confirm minimum essential coverage. Form 1095-B is used by insurers, plan sponsors of self-funded multiemployer plans, and plan sponsors of self-funded plans that have fewer than 50 employees to report on coverage in effect for the employee, union member, retiree, or COBRA participant, and their covered dependents, on a month-by-month basis.

Filers use Form 1094-B as the transmittal to submit the Form 1095-B return.

1095-B to IRS: February 28 for paper filers, or March 31 for electronic filers.
1095-B to employees: January 31 (IRS proposed regs with 30-day automatic extension)

1095-C and 1094-C

Form 1095-C is used to meet the ACA Section 6056 reporting requirement for Applicable Large Employers (employer shared responsibility/play-or-pay) and to determine whether an individual is eligible for a premium tax credit. Form 1095-C is also distributed to employees to verify coverage offering during the year.

Filers use Form 1094-C as the transmittal to submit the 1095-C return to the IRS.

1095-C to IRS: February 28 for paper filers, or March 31 for electronic filers.
1095-C to employees: January 31 (IRS proposed regs with 30-day automatic extension)


Form 5500 is the annual filing to DOL and IRS that plans with 100 participants or more use to report required information about the plan’s financial condition. Form 5500-SF can be filed for eligible plans with less than 100 participants. Form 5500-EZ can be filed for one-participant retirement plans or foreign plans. See the IRS Form 5500 Corner for information.

Due on the last day of the seventh month after the plan year end.


Employers may obtain an automatic extension to file Form 5500, Form 5500-SF, Form 5500-EZ, Form 8955-SSA, or Form 5330 by filing IRS Form 5558. The extension will allow return/reports to be filed up to the 15th day of the third month after the normal due date.

Due on or before the date the return/reports must be filed.


Employers use IRS Form 7004 to receive an automatic 6-month extension to file Form 8928 and other general business returns.

Generally, must be filed on or before the due date of the applicable tax return.


Employers use IRS Form 8809 to get an automatic 30-day extension of time to file Forms 1094-B or 1094-C.

Must be filed on or before the due date of the returns.


Employers and plan administrators should self-report any failure to comply with various group health plan requirements, including requirements related to the ACA, COBRA, HIPAA, Mental Health Parity, and the comparable contribution requirement for health savings accounts (HSAs), using IRS Form 8928.

Deadline to submit form and pay excise tax is plan sponsor’s federal income tax return filing deadline.

For MEWA, deadline is the last day of the seventh month following the close of the plan year.

Deadline for violating HSA comparable contributions requirements is April 15 following the calendar year in which the non-comparable contributions were made.


Multiple employer welfare arrangements (MEWAs) and Entities Claiming Exception (ECEs) are required to file Form M-1 with DOL to report required information about the MEWA’s custodial and financial condition (subject to certain exceptions).

Due by March 1 of the year following the calendar year for which reporting is required. An automatic 60-day extension is available if filed by the normal due date for Form M-1.


Employers must report the aggregate value of applicable employer-sponsored health coverage on Form W-2 for the prior calendar year. See the IRS page Form W-2 Reporting of Employer-Sponsored Health Coverage for information.

The deadline to file and furnish Form W-2 is January 31.

ICHRA – Individual Coverage Health Reimbursement Arrangement Notice

Employers that provide an ICHRA must furnish written notice to each participant containing specific information about the ICHRA. See the DOL model notice for information.

Notice must be provided at least 90 days before the start of the plan year.

For newly eligible employees, written notice must be provided no later than the date coverage may begin.

Medical Loss Ratio (MLR Rebates)

Issuers must spend a minimum percentage of their premium dollars, or MLR, on medical care and healthcare quality improvement. Issuers that do not meet the applicable MLR must pay rebates to consumers.

Sponsors of insured health plans may receive rebates if their issuers did not meet their MLR. Employers that receive rebates should consider their legal options for using the rebate. Any rebate amount that qualifies as a plan asset under ERISA must be used for the exclusive benefit of the plan’s participants and beneficiaries.

Rebates must be provided to plan sponsors by Sept. 30, following the end of the MLR reporting year.

Also, as a general rule, plan sponsors should use the rebate within three months of receiving it to avoid ERISA’s trust requirements. Plan sponsors that receive a rebate prior to Sept. 30 may need to adjust their deadline to use the rebate.

Medicare Part D Creditable Coverage Disclosure to CMS

Employers with group health plans that provide prescription drug coverage to individuals that are eligible for Medicare Part D must disclose to CMS whether the coverage is creditable prescription drug coverage. Employers must provide CMS with this information via the Disclosure to CMS Form completed and sent electronically through the CMS website.

See the CMS instruction guide with screenshots for completing the form online.

Form must be provided annually, within 60 days after the first day of the plan year for the reporting year. Also, within 30 days after the prescription drug plan’s termination or within 30 days after any change in the creditable coverage status of the prescription drug plan.

Medicare Part D Notice of Creditable Coverage to Plan Participants

The Medicare Modernization Act penalizes individuals for late enrollment in Medicare Part D if they do not maintain “creditable coverage” for a period of 63 days or longer following their initial enrollment period for drug benefits. Plan sponsors must disclose whether prescription drug coverage is creditable or non-creditable. CMS provides model notices for creditable coverage and non-creditable coverage disclosures in both English and Spanish.

Disclosures to individuals must be made:

  1. Prior to the Medicare Part D annual coordinated election period – October 15 through December 7 of each year
  2. Prior to an individual’s initial enrollment period for Medicare Part D
  3. Prior to the effective date of coverage for any Medicare-eligible individual that joins the plan
  4. Whenever prescription drug coverage ends or coverage changes so that it is no longer creditable or becomes creditable
  5. Upon request by a beneficiary

If the creditable coverage disclosure notice is provided to all plan participants annually, prior to October 15 of each year, CMS will consider items 1 and 2 above to be met.

QSEHRA – Qualified Small Employer Health Reimbursement Arrangement Notice

Employers that provide a QSEHRA must furnish written notice to eligible employees including a statement of the amount of each permitted benefit for which the employee might be eligible, a statement that the eligible employee must provide the amount of the permitted benefit to the marketplace if the employee applies for an advance premium tax credit, and a statement that the employee may be liable for any month in which they do not have minimum essential coverage.

Written notice to eligible employees at least 90 days before the beginning of each plan year.

For mid-year eligible employees, notice must be sent the date the employee becomes eligible.

Summary Annual Report (SAR)

Employers that are required to file a Form 5500 must provide participants with a summary of the information in Form 5500, called a summary annual report (SAR). Plans that are exempt from the annual 5500 filing requirement are not required to provide a SAR. Large, completely unfunded health plans are also generally exempt from the SAR requirement.


The plan administrator generally must provide the SAR within nine months of the close of the plan year. For calendar-year plans, this deadline is Sept. 30, 2023.

If an extension of time to file Form 5500 is obtained, the plan administrator must furnish the SAR within two months after the close of the extension period.
