Assessment & Taxation - Property Tax Prepayments

Washington County is unable to accept any prepayments on taxes for the 2019/2020 tax year. Per Oregon Revised Statutes, pre-collection of funds may not be allowed, unless under specific situations such as omitted property which adds taxes to the roll; prepayment to the Oregon Department of Revenue for senior deferral balances; partition and plats of parcels or making a subdivision; and other situations outlined in ORS 311.370. According to the Oregon Administrative Rules (OAR 150-311-0260) unless authorized by law, no prepayments of property taxes which have not been certified by a taxing district, shall be collected or accepted.
