Property tax deadline extended to June

King County Executive Dow Constantine announced today that the first half of 2020 property taxes for individual residential and commercial taxpayers has been extended to June 1.

“Many homeowners are facing extraordinary financial challenges during this public health emergency,” Constantine said in a March 30 press release. “My order provides short-term relief for individual taxpayers who own residential or commercial property, while allowing the state, county, cities and special purpose districts to continue meeting community needs as we all pull together to get through this unprecedented crisis.”

This deadline extension only affects those who pay their property taxes themselves, as opposed to through a mortgage lender. Additionally, banks and other financial institutions that pay taxes for their clients must meet the original April 30 deadline.

Even though taxes are now due in the summer, King County encourages anyone who can do so to still adhere to the April 30 deadline, or as soon as possible; no interest will be charged for those who pay by June 1.

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)

You currently cannot pay in-person, as services at the King County Treasury office and at Community Service Centers are remain suspended.

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.
