Island County Treasurer

2019 Property Taxes are certified and statements were mailed February 13.  Any unpaid balances remaining from prior periods are delinquent.  Balance information is also posted on this website (see the Make a Payment link, above).

If you do not receive a tax statement by mail, request that one be emailed to you by completing this online form.  Failure to receive a statement by mail does not absolve the taxpayer of the responsibility to make timely payment per RCW 84.56.050.  Checks received without appropriate interest and/or penalties included will be returned to the payer.
