Chelan County Assessor

Tax Bills and Payments

The Assessor’s Office is not responsible for mailing or collecting your taxes.  The Treasurer’s Office mails out all tax statements and collects the tax payments in Chelan County.

Tax Statements are mailed out to property owners in February by the Treasurer’s Office and the statement will show the amount of taxes due for that year.  If you do not receive a statement by March 1st, please call the Treasurer’s office at (509) 667-6405.

First half payments must be paid or postmarked by April 30th or the entire billing becomes delinquent and will accrue interest and penalty. Interest is 1% a month on delinquent taxes. A 3% penalty is charged on June 1st.  Second half taxes become delinquent after October 31st. An 8% penalty is charged on December 1st.

You can pay your taxes in person or by mail at the Chelan County Treasurer’s Office which is located in the Courthouse at 350 Orondo Avenue, Wenatchee.  If paying by mail, make sure to include the tax parcel number on your check and mail to PO Box 1441, Wenatchee, WA  98807-1441 .  You can pay your taxes by credit card or check over the phone by calling 1-877-673-6058 or online through Official Payments Corp.  For more information about this option visit the Chelan County Treasurer’s website.
