An entity defined by USDA as being eligible to receive federal farm program benefits, subject to annual payment limitation constraints. A "person" may be an individual farmer, an individual member of a joint operation, a corporation, a joint stock company, an association, a limited partnership, a trust, an estate, or a charitable organization. A husband and wife are considered one person for payment limitation purposes. A joint operation is not a person; neither is a cooperative association of producers that markets commodities for producers.
