Your Father will file the form 8962 on his return with the information for his and your mother's policy. It seems that this season the IRS is double checking the information form policies issued by the Market-Place. There have been quite a few customers who have received requests from the IRS to provide Copies of form 1095-A to be faxed or mailed to them. Your father will file with 8962, and at worst the IRS will request that he send a copy of form 1095-A.
On another note, please keep in mind that Social Security Benefits are not considered income to determine if an elderly parent is a dependent.
