delinquent taxes 

PLEASE READ THIS NOTICE!!

House Bill 18 was recently passed by the Montana Legislature. This changes the way delinquent taxes are processed and also changes the tax lien process.  If delinquent taxes are not RECEIVED by 7-30-2021, (post mark is not accepted) a tax lien certificate will be filed in the Clerk and Recorder’s office for each tax bill. Once a delinquent tax is paid after 7-30-2021, a redemption document will also have to be filed in the Clerk and Recorder’s office for each tax bill to redeem the lien. This is costly and time consuming. A $25.00 service charge will be added to the delinquent tax bill to cover the extra costs of this process.

Please pay your delinquent taxes before 7-30-2021.

If you have any questions, please contact the Treasurers Office.
