7 Pa. Code § 137b.81
If an owner of enrolled land changes the use of the land to something other than agricultural use, agricultural reserve or forest reserve, or changes the use of the enrolled land so that it otherwise fails to meet the requirements of section 3 of the act (72 P. S. § 5490.3), that landowner shall be responsible for the payment of roll-back taxes and interest, and preferential assessment shall end on that portion of the enrolled land which fails to meet the requirements of section 3 of the act. The owner of enrolled land will not be liable for any roll-back tax triggered as a result of a change to an ineligible use by the owner of a split-off tract. A transfer of enrolled land under a single application will not trigger liability for roll-back taxes unless there is a subsequent change of use so that it fails to meet the requirements of section 3 of the act, in which case the landowner changing the use shall be liable for payment of roll-back taxes on the enrolled land under that single application.
