title_body: Anonymous publishing
upvoted_answer: If your work is going to be successful enough to make it cost effective to set up all the legal niceties of staying hidden.  There is no possible way to guarantee you will keep your anonymity.  The recent article JK Rowling lawyer fined over Robert Galbraith leak(BBC 2 January 2014) is but one example of failure.
  
  If you are already an established author, your risk of exposure increases. 
  
  If you are not already an established author, your potential for recouping expenses is doubtful at best.  
  
  If anonymity is a significant concern, do not publish.  
  
  If anonymity is passing concern, then money is probably not a significant concern.  Publish all your works for free, or direct all incoming funds to a charitable concern without ever coming to you.
  
  There is no anonymity on the internet, there is only presence or lack of common knowledge (assuming anyone cares enough to look).  As of this minute there are 277,316 published works on Smashwords Many of them published with pseudonyms.  The majority of them make such a little splash, that no one is drawn to search out the authors.  But if the right people, care enough to look hard enough, there no possibility of sure anonymity.
