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! 2008 second half property taxes are due or must be postmarked by October 31, 2008 to avoid delinquency charges

It may take up to two weeks for your property tax payment to be reflected in our records after receiving your payment.
