Your insurance company will send you a 1095 form, which will also be transmitted to the IRS. If you were covered by a plan purchased through your state's Health Insurance Marketplace or Healthcare.gov, you'll get a 1095-A form. This information will be entered into your taxes.
If you were covered by a plan purchased directly through a health insurance company, government plan, or if health insurance was offered to you through your employer, you will receive a 1095-B or 1095-C form. These forms do not need to be entered into your taxes. You simply need to review the form you receive for accuracy and keep for your records.
Here is some additional information on this topic:
You should receive a form either from your employer, government agency such as Medicare or Medicaid! Or if you bought insurance through The Market place! 1095 B or 1095 C, you don't have file but 1095 A shows you bought through the Market Place and has to be filed!
