San Juan County Treasurer, Rhonda Pederson would like to remind county property owners that the first installment of property taxes and personal property taxes are due April 30.
Property tax payments must be federally post marked by April 30, or may be paid in person at the Treasurer's Office in the San Juan County Courthouse, 350 Court Street, 10:00 a.m. to 4 p.m., Monday through Friday or placed in our drop box at the Treasurer’s Office, 8 a.m. to 5 p.m., Monday through Friday.
Mail dropped off in a U.S. postal mailbox after the post office pick-up time could result in a postmark of May 1 and the payment would be considered delinquent.
Credit card or electronic checks may be used to make on-line payments at sanjuanco.com/treasurer or by phone, 877-816-9299. Instructions for both are on the back of the tax statement, and a 2.5% fee is charged by the service provider for credit card payments, or $3.95 for a debit card or $2.00 for an electronic check.
For taxpayers who signed up for autopay, your payment will be made automatically for the amount shown on your first half tax payment coupon on April 25.
Please call the Treasurer’s office at 360-378-2171 with any questions.
