Since the enactment of the Virginia Land Preservation Tax Credit legislation, Moyes & Associates has concentrated on the drafting of conservation and open space easements and the filing for various tax forms related to the easements. During the period from 2007 through 2010 the firm has participated in the preparation and qualification of easements in excess of $200 million in Federal charitable gifts and $75 million in Virginia tax credits.
