Remember, to get the discount for early payment of your Campbell County property taxes, we must receive your payment postmarked or made in person by end of business on November 30th. Remember, payments can be made at any Unity Bank in Campbell County as well. Postmarked means that the US Post Office has processed it for delivery. Simply getting it in the mailbox or metering it through a postage machine is not enough. It must be processed via the post office by December 1st. Processed is when the Post Office labels your postage paid as shown here.
