Closing Date Prorations in Oregon
Oregon law, under Or. Rev. Stat. § 311.505, establishes the closing date as the day the buyer becomes responsible for property taxes, with the seller responsible for taxes through the day before closing. The statute provides that the seller’s share of annual taxes is computed from July 1 through the day before closing, while the buyer’s share runs from the closing date through June 30 of the following year. No statutory rate or percentage is set for the proration itself; instead, the calculation relies on the annual tax amount and the number of days each party holds title. The official source from the Oregon Department of Revenue details the rule’s application. For an estimate of a specific transaction, the calculator below uses these statutory parameters.
