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 www.certifiedpayments.net tax online code: 8334605

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 to pursue an action.
