This is a great read

Perfectly Legal: The Covert Campaign to Rig our Tax System to Benefit the Super Rich- and Cheat Everyone Else, by David Cay Johnston:

"This book is about the reality of how our tax system actually operates after the politicians pass the laws. The news media do a good job of telling you the official version of events and what politicians in Washington say about taxes. But I spent a lot of my career covering Washington without being there by paying attention to what actually government does, as opposed to what the politicians say that it does. And I show in this book that our tax system is not what most people think."
