Farmers Tax Deferral Act - Amends the Internal Revenue Code to: (1) allow individuals age 55 or older to exclude from gross income the gain or loss from an exchange of qualified agricultural property for U.S. real property; (2) treat such an exchange as a like-kind exchange for purposes of recognizing gain or loss; and (3) allow installment sales treatment of qualified agricultural property. Defines "qualified agricultural property" as any single purpose agricultural or horticultural structure placed in service more than 20 years before an exchange and any real property, equipment, or fixtures related in use to such structure.
