There are a number of books available to help you better understand the U.S. federal taxation system and file your individual tax returns. For the most part, however, only tax professionals read them, so they're not exactly made for the tax layman. However, here's a list of tax books available at cch.com, "a leading provider of research products and software solutions for tax, accounting, legal, and business professionals."
"CCH's 2009 Federal Taxation: Comprehensive Topics is a popular teacher-created combination first- and second-level tax course that offers comprehensive one-volume coverage of all the most important tax concepts and principles for a solid grounding in federal taxation. It offers clear and concise explanation of fundamental tax concepts in the framework of today's tax practice. Covering both planning and compliance, the book strikes an effective balance between AICPA model curriculum demands and the favored approaches of the majority of today's top tax teachers."
"CCH's Federal Taxation: Basic Principles (2010) is a popular first-level tax course textbook that provides a clear concise explanation of the fundamental tax concepts covering both tax planning and compliance. Basic Principles strikes a perfect balance between the AICPA model curriculum (focusing on business tax) and the demands favored by most teachers (covering the fundamentals and building toward the complex). The book is also a favorite in distant learning, because of its clarity and direct approach--and it is also used in special programs like CFP courses."
"The CCH Principles of Business Taxation course (formerly Federal Tax Course) approaches the study of taxation from the perspective of the student who will become a business person faced with business decisions that are inevitably affected by tax considerations. This perspective leads to a very different coverage in this textbook -- coverage that is useful for accounting, finance and general business majors. The new edition focuses on the central concepts that build our tax framework and avoids small exceptions and details to ensure that the student can confidently master the critical underpinnings of federal taxation. It abandons minutia that not only affects a very small number of taxpayers, but also tends to change often. In this way, there are no wasted motions and students gain a stronger, more solid understanding of federal tax principles."
