The deadline to pay 2026 second half property taxes is Oct. 31, a news release from the Thurston County Auditor’s Office stated.
Because Oct. 31 falls on a Saturday this year, taxpayers have until Monday, Nov. 2, to pay without incurring late fees.
Options to pay property taxes include:
• Online: Pay online at www.thurstoncountywa.gov/departments/treasurer. There is no additional charge for an electronic check payment, but there is a 1.0% transaction fee for a debit card payment and a 2.3% transaction fee for a credit card payment. Thurston County does not receive any of the fees charged.
• Mail: Checks or money orders may be mailed to the Thurston County treasurer at the address below. Payments must be postmarked by Nov. 2. The U.S. Postal Service no longer guarantees same-day postmarks. Residents are advised to mail payment early.
• Drop off: Payments may be dropped in the green drop box located near the flag poles outside the Thurston County Atrium building at the address below.
• In person: Payments may be made in person at the Thurston County Treasurer’s Office during business hours at the address below. The same credit/debit card fees apply as with online payments.
The Treasurer’s Office location and mailing address are 3000 Pacific Ave. SE, Olympia, WA 98501.
