How do I pay my property taxes?
In Office: We can accept checks or cash in office. During closed or busy office hours, you can use the drop box located outside of the Treasurer's Office doors.

By Mail: Send a check in to:
Cowlitz County Treasurer
207 N 4th Ave
Kelso, WA 98626

By Credit Card: Please visit or call 1-855-857-3624. Credit/debit card payments are also acceptable in the Treasurer's Office.

All checks must be made payable to Cowlitz County Treasurer. If the payment coupon is not included please be sure to include the parcel number or account number.

Your payment must be postmarked by the due date to be considered timely, otherwise interest and/or penalty will apply RCW 01.12.070.
