Download the 2013 Supplement to Federal Income Tax at this link.
Federal Income Tax is organized around the four questions necessary to the construction of a tax system: what is the proper tax base; what is the proper rate; what is the proper time period; and who is the proper taxpayer. The book provides students with an introduction to the basic income taxing formula of the Internal Revenue Code and the methods applicable to working with complex statutory materials without overwhelming them with too many Code sections. The text adopts a learning approach that guides students through a systematic process of questioning, enabling them to learn the material in a step-by-step way, facilitating better understanding and synthesis.
