I am not an Indian citizen, but I have lived there long enough to have a good understanding of the system. Going against the law is very risky in India. The entire system is corrupt, and in case they catch you then be prepared to lose all of your life savings, reputation and current job (on top of a possible prison sentence). One thing I have noticed is that the punishment for white collar crime (such as tax evasion and concealment of income) is treated by the courts more severely when compared to blue collar crimes (rapes, murder, theft.etc). You may be able to get bail within 2-3 days if you commit rape, but if you do tax evasion then it is a non-bailable offense and you may undergo considerable prison time before you get parole.
