Due April 30: Real and personal property taxes
Published 1:30 am Saturday, April 18, 2026
Submitted by San Juan County.
The first half of property taxes and personal property taxes are due and payable to the San Juan County Treasurer on or before April 30. Find information regarding the 2026 tax season on the San Juan County Treasurer’s website: http://www.sanjuancountywa.gov/314/Treasurer.
Payments received in person, via our secure payment box, online or postmarked after the April 30 deadline, are automatically charged interest on outstanding balances. Please plan ahead to avoid interest charges.
How to pay your property taxes
Pay taxes online via the payment portal. This option allows you to pay for multiple properties at once (while avoiding multiple transaction fees!), receive an instant receipt and create an account to make future transactions even easier.
