Form 1095-C: This form is not entered into the tax return, but it should be kept with your tax records. You will answer the question in the Health Insurance section that you had health insurance all year. The insurance company will provide the IRS with the needed information. Form 1099-HC is for Massachusetts (MA) residents only and shows proof of minimum essential coverage.
Only the Form 1095-A, received by the Health Insurance Marketplace is entered into the federal tax return.
