While estate planning for Maryland farm operators can be complicated, a conservation easement can be an effective tool to include in your plan. Conservation easements can help reduce the value of a farm estate and ensure the land will continue to be available for agricultural use. Donating a conservation easement is one way to reduce federal and state estate taxes when the value of your estate minus permitted deductions exceeds the current estate tax exemptions. Under current federal and Maryland tax laws, donating a conservation easement to a qualifying group can result in favorable tax deductions.
