What if the monthly premium is $0 on my 1095-A?
You aren't allowed a monthly credit amount for any month that the enrollment premiums for the month were not paid by the due date of your return (not including extensions) unless the amount of the premium paid for
the month is sufficient to avoid termination of the coverage
for that month. If a 0 appears in Column A of your 1095-A for any month, you may not have paid your enrollment premium for the month by the due date of the premium.
If not paid by the due date of your return, enter 0 for the month.
If the enrollment premium for the month is paid by the due date of your return (not including extensions), enter the enrollment premium for the month even if your form shows 0.
