Payment plans
Payment plans are available for current year taxes and also for delinquent prior years. Read important details below.
Payment plans may be an option for paying 2023 property taxes
First-half 2023 property taxes are due April 30, 2023. The second-half 2023 property taxes are due October 31, 2023. Monthly payment plans are available if you cannot make payments by these due dates. Taxpayers must still pay the monthly interest charge when enrolled in a payment plan agreement.
Note: 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 a taxpayer wants 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 (RCW 84.56.020). 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 defaulting on a payment plan agreement will have all penalties added back to their tax obligation as required by state law. Payment plans can be established with monthly payments for up to 12 months.
- To participate in a payment plan a taxpayer must first sign agreements with King County Treasury and then with Evergreen Notes Servicing (ENS). ENS is the company that will receive and process your monthly payments. Taxpayers must pay a $15 monthly processing fee and a one-time $75 setup fee.
- Monthly payments must be sent directly to ENS. Monthly payments will not be accepted if sent to King County Treasury.
What is an 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, which are due by April 30, 2023
- The homeowner establishes a 12 month payment plan agreement on May 1, 2023, and choses to begin payments early in the same month. All monthly interest charges are factored into the payment plan as per State law.
- The one percent monthly interest charge and the monthly $15 processing charge is factored into the monthly payment plan. Also, please note, there is a one-time $75 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.
