If one had any questions as to the complex nature of our tax system, all one has to do is read the link posted at the top by k-semler
Our tax system is a farce, an abomination, ridiculous, oppressive, nonsensical, psychotic, retarded, nuts, bonkers, overbearing, a sham, counter productive and … phew … the ultimate ‘great money grab’ !!
