This project developed four lessons that reflect the 1981 tax laws as they relate to the use of investment credit and depreciation in farm accounting systems. Project staff reviewed tax laws and related materials and identified four lessons in farm management and supervised occupational experience that needed revision. Materials were then organized and appropriate lesson plans were developed for use in the vocational agriculture program. The lesson plans, part of existing Missouri vocational agriculture curriculum, cover farm records, managing taxes to maximize income, using depreciation/cost recovery and investment credit in a farm business, and setting up depreciation/cost recovery schedules and inventories. Each lesson contains an objective, study questions, references, handouts, teaching procedures, information sheets, sample forms, exams, and exam answers. (KC)
