A per acre property tax model is proposed for taxing plantation-grown timber in western Washington State. The taxable assets consist of the bare land value plus the reforestation investment necessary to establish the timber stand. Under this system, an annual ad valorem property tax, or a harvest yield tax that substitutes for all, or part, of the annual ad valorem tax is levied on the full value of the tax base. Thus, unlike the traditional case where an annual property tax is levied on modified bare land and timber values to reduce the deferred yield bias associated with long-lived timber crops, the tax base under the proposed system requires no comparable modification. A variety of input scenarios are used to compare the numerical consequences of applying the proposed tax system with those of a land only, a land plus timber, and a harvest yield tax system; all levied at full value. Further comparisons with Washington's existing forest tax system, which is composed of an annual ad valorem property tax on a legislatively mandated statutory bare land value and a 5% harvest yield tax imposed in lieu of an annual ad valorem property tax on maturing timber, demonstrates how highly modified Washington's current system has become to accommodate forest owners and temper the deferred yield bias the property tax theoretically fosters.
