The Affordable Care Act (ACA) requires organizations that employ more than 50 full-time employees to provide Form 1095-C to its full-time employees by March 31. This requirement goes into effect in 2016. Form 1095-C provides information regarding any employer-provided health insurance coverage or offers of coverage. It may also detail the months of coverage you and any spouse and/or eligible dependents had during each month. You will use the information on this form as proof of coverage for yourself and your enrolled family members. This information is proof to the IRS that you do not owe a penalty tax due to being uninsured.
