Property Tax Payment Information
RETURNED ITEM FEE
A $40 returned item fee will be assessed on all payment types returned by the bank to the Treasurer's Office for any reason. Payments will be voided for each parcel's taxes paid by that payment type. Taxes are then subject to delinquent charges.
CERTIFIED FUNDS REQUIRED
Certified funds (bank certified, cashier's checks and cash) are required for payment on all delinquent accounts subject to personal property distraint or property tax foreclosure.
PROPERTY TAX DUE DATES
Taxes are due on April 30th each year. Taxes $50 or more can be paid in two installments, half being due on or before April 30th and the second half due on or before October 31st of each year. There is NO grace period. The postmark (US Post Office Cancellation) is the determining payment date for all mailed payments (RCW 1.12.070). To comply with state statute, all payments are reviewed by postmark date to determine if they are on time. NOTE: The date written on your check will not be considered the payment date. If you drop your payment into any mail receptacle, you must make certain the US Postal Service postmark will be appropriate for the legal payment date. We are not responsible for US Postal Service postmarks. This is between the taxpayer and the US Postal Service. Please check with your local US Postal Service office for pick up and mail delivery cut off times. We suggest mailing early three (3) to (5) days early.
If a due date falls on a Saturday or Sunday, the next Monday is the acceptable due date for payments to be considered on time.
All accounts accrue interest at 1% per month on the FULL amount owing until paid. A 3% penaly is added on June 1st and an 8% penalty is added on December 1st. Administrative costs are added during the personal property distraint and real property collection and foreclosure process.
Personal property is subject to distraint proceedings as soon as it becomes delinquent in the year it is billed.
Real Property is subject to foreclosure proceedings three years from its due date.
