Welcome to the Property Tax Information System
Information As a King County taxpayer, you have online access to the same information about your property taxes as is available through our customer service staff.  You can:
  • View your tax and assessed value information
  • Pay the current year (non-delinquent) tax amount due online (A convenience fee will be charged for credit card and eCheck payments.)
  • Request a copy of your tax statement to be mailed to you
  • Read the Frequently Asked Questions page
  • View a demonstration of the payment process
Important!

2010 property tax bills will be mailed in mid-February.  Until that time, we will not know the 2010 tax amounts.  2010 first half property taxes are due or must be postmarked by April 30, 2010, to avoid deliquency charges.

Treasury Operations office will be closed and email will be unanswered on certain furlough days.
