Avoid Interest & Penalties
Delinquent or late payment of taxes are subject to interest and/or penalties as designated by RCW 84.56.020 at a rate based on the property type from the month of delinquency until paid.
Delinquent fees are assessed on the first day of each month.
If the first half tax is not paid by April 30th, the full amount becomes delinquent. Interest and/or penalty is assessed on the full amount of taxes due for the year.
To avoid additional charges, view your account information and make a payment by visiting our Property Tax Inquiry online tool.
