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 tax online (A convenience fee will be charged for credit card and eCheck payments.)
    • Pay current and/or delinquent real property tax
    • Pay current year (non-delinquent) personal property tax
  • 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!

2012 property tax bills will be mailed in mid-February.  Until that time, we will not know the 2012 tax amounts.  2012 first half property taxes are due or must be postmarked by April 30, 2012, to avoid deliquency charges.

It may take up to two weeks for your property tax payment to be reflected in our records after receiving your payment. If you pay by electronic check, you should see this reduction in your bank account within three business days even though our system may not yet reflect the payment.
