It never ceases to amaze me when people not only encourage one another but provide hints on how to cheat paying their taxes. There may be some of those terrible Europeans posting, they do seem to have a far more casual attitude to tax collectors, possibly stemming from a long tradition of hanging them in trees and firing arrows at them if they got too rapacious. Nowadays we take inspiration from the examples or Apple, Google,and Amazon (not to mention ebay) who avoid the European tax collectors on a truly impressive scale.
Look into "private treaty sales" ie: the only ones who know the details are you/buyer. You aren't required to fork over every cent you make to big brother YET so keep it to yourself and hide the proceeds. I will when I sell mine....
