In an effort to preserve agricultural and forest land, Pennsylvania passed The Pennsylvania Farmland and Forest Land Assessment Act of 1974, also known as Clean and Green. Clean and Green provides qualified parcels of land with preferential assessment values, resulting in lower property taxes for the landowner. A Clean and Green qualified parcel generally must be more than 10 acres in size and devoted to agricultural use, agricultural reserve (i.e. open spaces used for outdoor recreation), or forest reserve. Rather than appraising the parcel based off of its Fair Market Value, Clean and Green allows the Department of Agriculture (DOA) to value parcels based on their use. The DOA provides county assessment offices with a list of use values annually. Each county’s assessment office is allowed to provide for lower assessment values for Clean and Green qualified parcels, but may not assess a parcel higher than the use values provided by the DOA. Currently, Pennsylvania has more than 9.3 million of its total 29 million (~32%) acres of land enrolled in Clean and Green.
While Clean and Green assists many Pennsylvania farmers that may otherwise face financial struggles, the program also disincentivizes those landowners from changing the use of their land or selling it for non-agricultural purposes. In the event a landowner violates the Clean and Green covenants or elects to remove the parcel from the program, the landowner is subject to up to seven years of rollback taxes at a 6 % interest rate per year (or, if the parcel was enrolled in Clean and Green for less than seven years, rollback taxes for the number of years the parcel was enrolled). Rollback taxes generally means the amount of taxes that would have been paid had the parcel not been enrolled in Clean and Green, less the taxes due by virtue of the program. In the event the parcel is sold to a third party, rollback taxes will not become automatically due because of the sale itself. If, however, a third party purchases the parcel and changes its use, the parcel—thus, the third-party purchaser—can become subject to the rollback tax penalty.
