Should I pay my property taxes while appealing?
Yes—you must keep paying property taxes while an appeal is pending. Filing does not pause the bill or deadlines; late payment risks penalties, interest, and tax sale. If the appeal succeeds, you may get lower future bills or a refund of overpaid taxes. Escrow lenders typically keep paying during the appeal.
