If I appeal my property value, do I have to pay my property taxes while under appeal?

You must pay at least the appeal amount by the due date to avoid a 1% penalty. You cannot defer payment. The Tax Assessors' office is not authorized to extend the payment deadline. 1% interest per month (up to $150) accrues on the remaining balance. You may choose to pay the full amount of the bill by the due date to avoid paying interest.
