Current Use is fair taxation. In order to encourage the use of land for agricultural production or forest management, the state of Vermont has adopted policy that allows farmers and forestors to enroll their land in Current Use and then the land is taxed at the use value rather than the fair market value - so the land is appraised as what it is used for rather than what it could be sold for at the highest market value. Farmers and forestors then pay taxes based on this appraisal rate, which is calculated through a statutory formula.
The state created Current Use "to encourage and assist the maintenance of Vermont's productive agricultural and forest land; to encourage and assist in their conservation and preservation for future productive use and for the protection of natural ecological systems; to prevent the accelerated conversion of these lands to more intensive use by the pressure of property taxation at values incompatible with the productive capacity of the land; to achieve more equitable taxation for undeveloped lands; to encourage and assist in the preservation and enhancement of Vermont's scenic natural resources; and to enable the citizens of Vermont to plan its orderly growth in the face of increasing development pressures in the interests of the public health, safety and welfare." - 10 VSA 3751
