This book is designed for a clinical program or pro bono program that assists low income taxpayers with federal income tax controversies. It draws from four main areas: lawyering skills of interviewing and counseling; ethics; federal tax practice and procedure; and federal tax litigation. Appendices with examples of documents and letters are included to provide practical material. Basic information in the four areas is presented through a combination of commentary, cases, excerpts from federal tax law and procedure, and questions for discussion Appendices provide sample documents that compliment the topics. Unlike other law school case books, the cases have not been extensively edited because the book is meant to provide students and practitioners the opportunity to fully explore and understand the facts and holdings of the cases. Generally, footnotes in reprinted cases and other materials are numbered as in the original. The student who completes a course using this book should have a firm grounding in tax practice and procedure common to tax controversies of individual taxpayers. Practitioners who use this book will be prepared to assist low income taxpayers pro bono, be part of volunteer work with a low income taxpayer clinic or bar association program. While the organization of the book is based on an ideal of how material should be presented, professors can rearrange the reading based on the topics presented in current clinic cases. Practitioners can pick and choose the chapters applicable to their cases, but should not skip the chapters on lawyering skills. Future editions will add chapters on the holistic representation of low income taxpayers (including social and other legalissues that may arise in legal representation), tax issues of importance to immigrants and federal tax crime issues.
