How it works
We send personal property forms for existing accounts at the beginning of each year. They must be returned by April 30. We don't grant filing extensions and apply a tax penalty of 5% per month to listings received after the deadline, up to 25% of the amount due. The assessor may waive the penalty if the late filing is due to reasonable cause.
The listing form includes instructions for completion. Have questions about how or what to report? Call the number on the first page of the document.
Download the personal property listing form (249KB) if you haven't filed before. You can also request the form by phone or email.
You can file online with eListing.
You don't need to sign the form but include the preparer's contact information.
Watch an overview of personal property tax.
We'll use the information you provide to calculate an assessed value. It's reflected on the valuation notice that we'll send to you.
To determine personal property taxes, we multiply this value by the levy rate for your business's location. The valuation notice also provides information about appealing the valuation.
Around mid-February of the following year, you should receive a tax bill from the King County Finance Division. It shows the assessed value from the Personal Property Valuation Notice and the amount of taxes due.
