Snohomish County Assessor, Personal Property Division Services
Advance Tax Request

It is the duty of a seller or its agent to advise Snohomish County in advance of a business sale, closure, relocation in or out of the county to ensure the Personal Property Advance Tax is billed and paid. 

Failure to inform Snohomish County may result in a real property sale transaction being rejected at the County recording office because the Advance Tax research has not been conducted and duly noted on the property being sold. This is particularly true on commercial real estate or any real property parcel that may have a business or personal property account associated with it. 

 Please ensure that you are in possession of all relevant real property parcel numbers and business personal property account numbers prior to all personal property submissions. 

Look for the following numbers on your assessment notices or tax statements 

  • Real property accounts are 14 digits in length.
  • Business personal property are a 7 digits number or an 11 character identifier beginning with "BPP".
  • Real Property and Business Sale/Refinance- File when reporting the sale of a Real Property AND a business or a Refinance.  Please have both the real property parcel number and the personal property account number available for completion of the form. 
  • Closure/Relocated in County/Relocated out of County/Bankruptcy-File when reporting a closure, relocated in county, relocated out of county or a bankruptcy of a business. Please have your business personal property account number available for completion of form
