Health Insurance Premium Tax Credit - Clergy

Hello! I am working with a member of the clergy on their insurance and have a few questions regarding the Premium Tax Credit (Form 8962):

 

  1. The client receives a gross income of $50k. The client also receives a separate allowance for their mortgage of $30k.  Does the housing allowance count toward their estimated household income when calculating the amount of the credit? Or should only the $50k be used when calculating the credit?
  2. Currently, the church pays directly for their health insurance. In order to receive the PTC, would the client need to pay for insurance themselves?
  3. If the client receives the credit, but it was miscalculated, would they repay the balance on their tax return?

Thank you in advance!
