First half of 2020 property taxes due June 1

Individual residential and commercial taxpayers who pay property taxes themselves, rather than through their mortgage lender, have until June 1 to pay the first half of their 2020 property taxes. King County Executive Dow Constantine issued an order in March giving these taxpayers an extension due to the COVID-19 (coronavirus) pandemic.

The county will not add interest charges or penalties to the tax bill for individual taxpayers who pay the first half amount due by June 1. The deadline will not be extended further, as taxing districts rely on these revenues to support critical operations and to make June debt service payments.

Banks and other financial institutions that pay property taxes on behalf of their lending customers were required to meet the original April 30 payment deadline, and they have done so.

Property tax payments can be made:

  • Online at kingcounty.gov/PropertyTax using a credit or debit card or by eCheck (a processing fee applies to these options)
  • By mail using a check or money order addressed to Treasury Operations, King County Administration Building, 500 Fourth Ave., Suite 600, Seattle, WA 98104 (cash should not be sent through the mail)
  • Via check or money order using the specially marked secure dropbox at the King County Administration Building in Seattle (cash payments may not be deposited in the dropbox)

Because of the ongoing pandemic, in-person payments at the King County Treasury office and at Community Service Centers are still suspended until further notice.

Taxpayers with questions about their property tax bill or payment options can contact King County Treasury at propertytax.customerservice@kingcounty.gov or 206-263-2890.
