This book deals with the ethical issues and problems facing tax lawyers and tax professionals, which have become increasingly complex. It provides a useful complement to the general rules of professional responsibility, which do not always provide clear answers to the problems tax professionals face. It deals with the specific problems that often arise in the tax field and considers the model rules of professional conduct, discussing those rules in the context of tax cases. This text can be used in a seminar class or as a supplement in a basic tax class.
