The property tax for the second half of 2013 is due to the Whatcom County Treasurer's Office by Thursday, Oct. 31.
Those mailing their payment should make sure it is postmarked by Thursday, so put it in the mail before the due date, Treasurer Steve Oliver said.
Late payments result in an added interest charge and a late fee.
