The deadline for Thurston County residents to pay the first half of their property taxes is April 30, but because that is a Saturday the law allows the payment to be made on the next business day, May 2, without interest.
Property taxes can be paid through the Thurston County Treasurer’s website. There is no additional charge for the electronic check payment option online, but there is a 2.75 percent fee for the credit/debit card payment option. Payments also can be made at the Treasurer’s Office or the courthouse parking lot drop box at 2000 Lakeridge Drive SW, Building 1, Olympia.
Payments made by mail must be postmarked by the due date. Penalties and interest will be charged for payments not received on time.
