If your Winter tax bill shows a summer amount due, please contact the Treasurer for verification before remitting. There was an import error at the County that may result in an incorrect calculation of taxes due from the Summer season. Some bills that were paid in full on the September 16 due date are showing interest due in error. Call the Treasurer at 989-743-4381, ext. 2, or email your question to treasurer@newhavenshiami.gov so we can resolve it.
