Property Taxes

Tax Payments
Your property taxes can be paid using cash, check, or credit card. We will need your Tax ID number or we can search by owner’s name.  Checks should be made payable to Blaine County Treasurer and mailed to PO Box 547 Chinook, MT 59523.  Call our office to pay with a credit card or use jurisdiction code: 3630

Tax Protest
To pay taxes under protest, your payment must be received by the due date.  You are required to submit a Letter of Protest for each tax bill at the time of payment.  Your payment is processed immediately, but the funds are not distributed until the protest is settled.  Paying under protest allows the taxpayer 90 days to take further action and it is the responsibility of the taxpayer pursue an action.

Delinquent Taxes
A list of Delinquent Taxes is available for inspection at the Treasurer’s Office.  Blaine County attaches a tax lien to all real estate properties with delinquent taxes on the first working day of August.  If you have delinquent taxes and need more information, please call (406) 357-3280.  Anyone interested in tax lien assignments and tax deeds should consult an attorney.
