Fall Property Taxes due for the last half of 2008

Residents can pay using King County’s efficient and secure online payment system

King County property owners have until October 31st to pay 2008 second-half property taxes. After that date, state-mandated interest charges and penalties will be added to the tax bill. To make the process easier, King County provides several ways for property owners to pay their taxes quickly and conveniently.

Tax payments can be made:

  1. By mail if postmarked no later than October 31, 2008. Taxpayers should include their tax statement and write the property tax account number on their check or money order. Cash should not be sent through the mail.
  2. In person at Room 600 - Treasury Operations, King County Administration Building, 500 4th Avenue, Seattle, 98104, Monday through Friday between 8:30 a.m. and 4:30 p.m.
  3. At community services centers if paid by check in the exact amount due. The address, phone numbers and operating hours of the King County Community Service Centers are online at http://www.kingcounty.gov/csc/.
  4. From a computer using King County’s online eTax application with a credit card or an electronic debit from a checking account called an “echeck.”

The online option provides an easy, secure and immediate payment confirmation for current year, non-delinquent property tax bills. Delinquent accounts are not payable through the online payment system.

To pay online or view property tax information, taxpayers can visit: http://www.kingcounty.gov/propertytax/.
