Real and Personal Property Taxes Due April 30

San Juan County Treasurer, Rhonda Pederson, would like to remind county property owners that the first half of property taxes and personal property taxes are due April 30.

Payments received in person, via our secure payment box, 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:

By secure drop box: The box is located at the Court House entrance on the Sheriff side of the building.

By phone: Payments may be made using our automated phone attendant by calling 877-816-9299.

By mail: The envelope must be federally postmarked on or before April 30 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.
