Payments towards a house

Flathead County does not send an additional statement for the May 31st 2nd installment of Real Estate Taxes.

Interest of 5/6 of 1% per month plus 2% penalty must accompany delinquent taxes paid after due dates.  This amount must be obtained by contacting the Treasurer's office PRIOR to payment.


OWNERSHIP INTEREST

Tax notices must be issued in the name of the owner of record as the property stood on January 1 of the taxing year.  Therefore, properties that changed hands, were re-recorded, split or subdivided during the current year may not be reflected until the following year. If you have further questions regarding any of the services the Flathead County Tax Department provides to the Community please call us at (406) 758-5680.
