Report health insurance information Minimum Essential Coverage Information Reporting (MEC IR)

Insurance providers are required to report health coverage information to us annually by March 31 or face a penalty. However, no penalty will apply if the return is filed on or before May 31. Employers are similarly required to report insurance information to us by March 31, but only if their insurance providers do not report to FTB. This requirement comes from the Individual Shared Responsibility Penalty that was enacted at the same time as the health care mandate. The penalty for not reporting is $50 per individual who was provided health coverage.

The deadline for reporters to provide information returns to individuals is January 31, and no extensions are available. FTB does not impose a penalty for a failure to provide returns to individuals by this deadline.

For information on reporting instructions, review Publications.
