The second half of property taxes and personal property taxes are due Friday, October 31, 2025.


||| FROM SAN JUAN COUNTY COMMUNICATIONS |||


The second half of property and personal property taxes is due Friday, October 31, 2025, and the San Juan County Treasurer’s Office is making it easier than ever to pay quickly, securely, and on time!  Remember, the Treasurer’s Office is closed on Fridays – but don’t worry! There are many ways to pay taxes early, online, and in-person before the deadline.

Online Payments

Accessed via the Treasurer’s Office webpage, a new online portal allows you to pay for multiple properties at once (while avoiding multiple transaction fees!), schedule on-time payments, receive an instant receipt, and create an account to make future transactions even easier.  The online portal aims to make paying and processing taxes much faster, easier, and more cost-effective.

Use the online portal to pay your taxes:

  1. Visit the Treasurer’s Office website at: https://www.sanjuancountywa.gov/314/Treasurer
  2. Click the menu option on the left ‘Pay Taxes Online’ https://www.paydici.com/san-juan-county-treasurer-wa/search/property-tax-group
  3. Use the link to the online portal to begin creating an account

Other Payment Methods

Payments may also be made using our automated phone attendant by calling 877-816-9299.  These are contracted services and processing fees apply:

  • Credit Card processing fee 2.7%
  • Debit Card processing fee 0.95%
  • eCheck processing fee $2.00

Property tax payments received in-person, via our secure payment box or postmarked after the October 31 deadline are automatically charged 1% interest on outstanding balances. PLEASE plan ahead to avoid interest charges.

A secure payment drop box is located at the Court House entrance on the Sheriff side of the building.  If mailing your payment, the envelope must be federally postmarked on or before October 31 for the payment to be considered on time.  Keep in mind, although you place your payment in the mailbox, federal postmarks often happen the next business day. If mailing your payment less than a week prior to the deadline, we strongly recommend having your envelope hand canceled by the postal agent.

Mailed payments may be addressed to: 

San Juan County Treasurer

PO Box 639

Friday Harbor, WA 98250

Taxpayers enrolled in our autopay program should expect the second half payment for the amount listed on your second half tax payment coupon to debit your account on October 27, 2025.

Unsure what your property tax balance is or if you’ve already paid?
