2023 Property Taxes

In accordance with RCW 84.56.020(1), the San Juan County Treasurer is providing notification that the 2023 tax roll has been completed and tax statements are anticipated to begin arriving in mailboxes by the end of February 2023. All real and personal property taxes and assessments are due and payable to the County Treasurer on or before April 30, 2023.

In the event you do not receive a tax statement via mail or eNotices, please contact our office at 360-378-2171. Failure to receive a tax statement by mail will not forgive any taxpayer for timely payment per RCW 84.56. Tax information can also be located via the county property search.
