Closing Date Prorations in Washington
In Washington, closing date prorations for property taxes are governed by RCW § 84.56.020, which establishes that the seller is responsible for taxes up to and including the day of closing, and the buyer assumes responsibility thereafter. The statute treats the tax year as an annual cycle, with taxes levied in one year payable the following year. Proration is calculated based on the precise number of days each party holds ownership during the tax period. The official source at myticor.com details this annual cycle, and the calculator below provides a step-by-step worked example showing how the proration is computed. For an estimate tailored to a specific closing date, use the DocketMath proration calculator.
