Payment plans

Information about how to pay delinquent property taxes and set up payment plans

To help taxpayers impacted by economic hardship, King County has a property tax payment plan program available for real property homes, commercial businesses, land, and mobile homes.

To participate in a payment plan, property owners must sign an agreement with King County Treasury. Payment plans are calculated using tax, interest, and statutory penalties through the end of the plan and then broken down into monthly payments for six or 12 months. Payment plans are available for delinquent prior year(s) taxes only, and cannot go beyond the status of subject to foreclosure.

If participating owners also have a mortgage, they need to notify their lender about the payment plan.

The program is administered through a third-party vendor, Evergreen Notes Servicing (ENS). Monthly payments are credited to the property tax account once the terms of the payment plan are met. All payments must be made to ENS by the 5th of each month in order to ensure payments are received by Treasury without additional interest owing.

If you are inquiring about a commercial business or have a mobile home, please call 206-263-2844 to inquire about payment plan options.

How does a payment plan work?

Spreading out your tax obligation into monthly payments can be easier to manage for some taxpayers. However, there are important factors to consider if you want to participate in a payment plan.

  • Payment plans do not reduce or eliminate your obligation to pay applicable late charges as specified in state law. The extent to which late charges are applicable depends on the date you start your payment plan.
  • Payment plans must factor in monthly interest charges throughout the duration of the payment plan, as required under state law.
  • Taxpayers who default on their payment plan will have their plan canceled. Depending on when or which year defaults, a new plan may be established.
  • To participate in a payment plan a taxpayer must first sign agreements with King County Treasury and with Evergreen Notes Servicing (ENS). ENS is the company that will receive and process your monthly payments. Taxpayers must pay a one-time $100 setup fee and a monthly $17 processing fee.
  • Monthly payments must be sent directly to ENS. Monthly payments will not be accepted if sent to King County Treasury.

Example of a typical payment plan

The below example will help to understand how a monthly payment plan is structured.

  • A homeowner has a tax bill for the year 2023, totaling $5,000. However, the homeowner does not expect to have funds to pay the first half taxes of $2,500.
  • The homeowner establishes a 12-month payment plan agreement on May 1, 2024. All monthly interest charges are factored into the payment plan as per state law.
  • The one percent (1%) monthly interest charge and the monthly $17 processing fee is factored into the monthly payment plan. There is also a one-time $100 setup fee.
  • In this scenario, the homeowner will make 12 monthly payments of roughly $480, which includes the monthly interest and monthly processing fee. When the terms are met after 12 months, the homeowner will have paid roughly $780 in interest and processing fees.
