DID YOU KNOW?

Personal property used in a business on January 1 must be reported in that year to the assessor if your business is physically located in King County. The location of the owner's residence is not relevant unless that is also the location of the business.

Reports must be filed by April 30 or the taxpayer will incur a monthly penalty of 5 percent of the tax due, not to exceed 25 percent.

We use information taxpayers provide on their Personal Property Listings to assess personal property used in businesses as of January 1 of the reporting year. Please see the links below for information to help you accurately report your business assets.
