2021 property tax statements coming soon

Property tax statements for 2021 will be mailed to King County taxpayers on or around February 15. If a mortgage lender pays your taxes, tax statement details are forwarded to them. If you pay your property taxes yourself and you have not received a statement by March 1, request a tax statement online at, contact King County Treasury Operations at, or call 206-263-2890.

The first half of your 2021 property taxes are due by April 30. This deadline will not be extended, unlike in 2020 when a one-time extension was implemented due to the then-emerging COVID-19 pandemic. The Pierce and Snohomish county treasurers are also maintaining this deadline in their jurisdictions.

To help taxpayers facing economic hardship, King County continues to offer a payment plan program first launched in 2020. This program is available for real property homes, commercial businesses, land, and mobile homes in King County. To participate, property owners must sign an agreement with King County Treasury. If participating owners also have a mortgage, they need to notify their lender about the payment plan agreement. The program is administered through a third-party vendor and monthly payments are credited to the property tax account once the terms of the payment plan are met.

For taxpayers participating in a 2021 payment plan, King County is currently waiving the $75 program setup fee for qualified taxpayers, but participants will need to pay a monthly processing fee charged by the vendor. Those taking part in the program will also need to pay interest of one percent (1%) each month on the outstanding amount of their tax bill, as required by Washington state law. However, the three percent (3%) penalty applied annually on June 1 for outstanding property taxes is waived for those enrolled in a payment plan. A payment plan for 2021 taxes can be made for a term of up to 18 months. For more information on the program, visit or email

King County's in-person services are still suspended due to COVID-19, but the Treasury website at lists other ways residents can access services. Taxpayers can also use that link to sign up for text and email reminders about their property taxes.
