You should receive Form 1095-A if you enrolled in a qualified health plan via the federal Health Insurance Marketplace or a state’s exchange.
The Form 1095-A provides consumers with certain information about their Marketplace health coverage during the prior year so they can file their federal income taxes, reconcile any advance payments of the premium tax credit (APTC) received, and claim the premium tax credit (PTC). Consumers need the information on Form 1095-A to complete Form 8962. Consumers must complete Form 8962 and file it with their federal income tax return if they want to claim the PTC or if they received APTC (consumers receiving APTC are required to file a federal income tax return).
If your actual income was lower than what you estimated, you are eligible for a larger premium tax credit and can claim the difference as a refund when you file your tax return. If your income was higher than what you estimated, you are eligible for less premium tax credit and might have to pay back some or all of the difference when you file your return.
