Yes, he will use your 1095-A form.
Please see this response from ShawnaD. It is written for the "child" point of view, but it still applies.
How you enter the information depends on if your parents are claiming you as a dependent on their tax return.
Please see the information below from Superuser TaxGuyBill:
- If your parents told the Healthcare Marketplace (usually when they applied for health insurance) that you were not going to be their dependent, you will probably receive a 1095-A of your own, and you will need to enter that into TurboTax. (instructions included further down below)
- If your parents did NOT tell the Healthcare Marketplace (usually when they applied for health insurance) that you were not going to be their dependent, you will NOT receive a 1095-A of your own.
-
- You will need to get a copy of your parents' 1095-A and enter it on your tax return. On the screen after entering the 1095-A, you will check the box indicating that the policy was shared by somebody that is not on your tax return. It will then prompt you with further questions to determine how much of it is "allocated" to you (even if it is 0%). Your parents would follow this same procedure.
-
- If there was Advance credit received (column C of the 1095-A), your parents have the option to claim 100% of the 1095-A on their tax return, or to "allocate" part (or all) of it to you. If you both agree, the allocation can be anywhere from 0% to 100%. If you can not agree and Advance credit was received (column C on the 1095-A), then it is divided by the number of people on the insurance policy. For example, if the insurance policy covers 4 people, each person is allocated 25%.
