If you own or operate a business in San Juan County, the assessed value of the equipment you use to run your business is taxed. This tax is called a personal property tax and it applies to businesses in every county in Washington State and most states across the nation. State law requires every business to report their personal property each year to the Assessor for assessment purposes. Our goal is to assess equipment your business owns at a fair value. 

Below is a brief description of the Personal Property Appraisal Process:

2020 Personal Property Timeline

The primary characteristic of Personal Property is its mobility. It includes most machinery, equipment, furniture and fixtures associated with commercial, industrial, short-term rental or agricultural enterprises. Business inventories are exempt from property tax. However, supplies consumed in the operation of a business are taxable. The Assessor uses the Listing provided by the business owner to value property for taxes due the following year. Personal Property tax rates are the same as for real property. An example of real property is your home.
