An estimation of assessed value will be applied to businesses that fail to complete the filing process by April 30 or within 30 days of the date of the filing notice, whichever is later. Estimated values do not depreciate and are subject to change annually. Failure to provide the detailed asset listing may result in an on-site audit.
By law, property owners are responsible for filing the personal property listing every year. This is true even if the property owner does not receive the personal property listing information. The penalty for failing to file a personal property listing is 5% per month of the total assessed tax due the following year, up to a maximum penalty of 25%. (Washington State Law RCW 84.40.130)
