The need to submit corrected forms.
A few reasons that might prompt the need for a correction include an incorrect name, social security number, or employer identification number. However, there may be other reasons that might be completely out of the employer’s control, such as an employee’s decision to terminate coverage later in the year.
In fact, the rules for reporting have gotten so complicated that it’s entirely possible that some employers may have to submit corrected forms even if the information they originally sent was accurate at the time the form was completed. For example, if an employee chooses COBRA and coverage must be restored retroactively.
The forms required are the 1095-B for employers who provide health benefits through an insurer and the 1095-C for those who use a self-insured group health plan.
These forms should be provided to employees and other insureds by February 1, 2016. The employer must then submit them all to the IRS, along with a 1094-B or 1094-C summary sheet, by February 29, 2016 if filing on paper or by March 31, 2016 if filing electronically.
