Does one have to file by April 15 or can one file an extension?
H & R Block advises to file a return and reconcile your credit by April 18, or request an extension so you have more time to file your taxes. An extension will give you until October 17 to file your return and reconcile any credit you received through the Marketplace.
Will I have to file a federal income tax return to get the premium tax credit?
Yes. For any tax year, if you have APTC in any amount or you do not have APTC but you plan to claim the premium tax credit, you must file a Form 8962, and attach it to your federal income tax return for that year. If you have any APTC, you will use Form 8962 to reconcile the difference between the APTC made on your behalf and the actual amount of the credit that you may claim on your return. This filing requirement applies whether or not you would otherwise be required to file a return.
If APTC is made on behalf of you or an individual in your family, and you do not file a tax return, you will not be eligible for APTC or cost-sharing reductions to help pay for your Marketplace health insurance coverage in future years. This means that you will be responsible for the full cost of your monthly premiums. IRS.gov
