OPTIONS FOR PAYING YOUR TAXES
PAY BY MAIL
Return your tax payment coupon(s) along with your check made payable to the Island County Treasurer. We cannot accept post-dated checks. Please be sure that the postmark on your envelope is on or before the due date to avoid incurring interest and/or penalty. If you want a receipt, you must enclose a self-addressed, stamped envelope. Please mail to the following address:
Island County Treasurer
PO Box 699
Coupeville, WA 98239-0699
PAY IN PERSON
Stop by the Treasurer's office between 9:00 a.m. and 4:00 p.m. Monday through Thursday. For our location, see Contact Us.
After hours, you may also drop your payment in the secure outside drop box located behind the Administration Building off 6th Street. You may park in the customer parking lot. The drop box is next to the glass door. During office hours, you may also drop your payment in the inside drop box to avoid waiting in line during the busy tax season. NO CASH in drop boxes.
