BLOOMINGTON, Ill. (WMBD) – The Family Farm Preservation Act is in the works with Illinois lawmakers who hope to protect the state’s main source of income. The “Family Farm Preservation Act” is to reevaluate the burden of estate taxes, by taxing farmers based on agricultural use, rather than what their land is worth if it were sold for development. The Internal Revenue Service set the original rules the new act will be updating in 1976. Those rules do not take inflation into account.
