ACA Form 1095-B/C Reporting Deadline, Penalties, and Extension for 2026

According to section 6056, each year, applicable large employers are required to file Form 1095-C with the IRS and provide copies to employees before the deadline to avoid penalties for late filing. Employers must file ACA Form 1095-B/C to report employees’ health insurance coverage details to the IRS. It’s essential for employers to annually submit these forms to both the IRS and the states and provide copies to employees before the deadline to prevent potential IRS penalties.

1095-C filing for Applicable Large Employers

Firstly, the requirements apply to all Applicable Large Employers (ALEs). An ALE is generally an employer with at least 50 full-time employees, but you should verify your status with your Tax Advisor.

To satisfy the reporting requirements, fully insured and self-insured applicable large employers must complete Form 1095-C for all full-time employees. Employers with fully insured plans must complete Parts I and II of the 1095- C, while those with self-insured plans will complete Parts I, II, and III.

Part 1: Employee; Applicable Large Employer Member
Part 2: Employee Offer and Coverage (including Plan Start Month)
Part 3: Covered Individuals

To report the necessary information to the IRS and furnish a form to employees, employers will need to capture:

• Identification of full-time employees for each month
• Employee’s identifying information: name, address, Social Security number (SSN)
• Employer’s identifying information: name, address, Employer Identification Number (EIN)
• Details about health coverage offered each month, if applicable
• Employee’s share of the monthly premium for the lowest-cost, self-only minimum value coverage
• Months the employee was enrolled in coverage
• Months the employer met an affordability safe harbor for an employee and any other applicable relief for a month
• If the employer offers a self-insured plan:
  • Information about covered individuals’ enrollment in the plan by month (including spouses and dependents)
  • This information includes Social Security numbers or, if unavailable, date of birth.
