On real property, you may pay any delinquent year in full including interest and penalty without paying the current year.  You should note, however, that the property is subject to foreclosure when the taxes become three years delinquent (RCW 84.56.060).

When personal property has been delinquent for 30 days, it becomes subject to distraint and sale (foreclosure).

The Treasurer's Office does not provide information directly to credit reporting agencies.  However, credit reporting agencies may contact other companies with whom you have a financial relationship (e.g. banks, mortgage company, etc.) to acquire information.

Washington State law does not allow the Treasurer to accept partial payments.  (RCW 84.56.020)

Foreclosure on real property occurs when the taxes are three years delinquent.  Foreclosure proceedings begin the year following the third year.

Personal property becomes subject to distraint and sale any time after 30 days of delinquency.

Personal property is typically "mobile" and includes, but is not limited to, machinery, furniture, fixtures, and equipment.

Every business must complete a personal property affidavit by April 30 each year and file it with the Island County Assessor's office for taxes due the following year.  Personal property rates are the same as for real property.

Washington statutes strictly regulate the reasons the Treasurer can waive interest and penalties.  These are:  death of a spouse or guardian or an error made by the County.
