Unique in its structure, Federal Income Taxation presents core materials that cover the basics of tax law and also offers “cells” at the end of each chapter that are self-contained units with more in-depth discussion of certain topics. This flexible structure allows professors to customize their tax course by selecting only the additional in-depth materials they want to use. The stellar author team, with years of scholarship and teaching experience, presents a core text that covers the leading cases and explains the substantive tax law that is essential to a basic understanding of federal income tax law and principles. The self-contained, optional units at the end of the book — “cells” —supplement the core text by providing additional material and treat a limited number of topics in greater detail. Notes and questions provide background information and place the cases and statutes in context. More than 150 problems are interspersed throughout the core text and the cells that challenge students to apply the Code, regulations, and income tax theory to specific situations. A detailed Teacher’s Manual provides comments and suggestions for teaching both the core and the cell material as well as answers to all of the questions and problems in the casebook.
