Mr Chidambaram has launch VDIS in 1997 for voluntry disclosure of Income scheme. In which people who have unaccounted money get the opportunity to disclose. Now we have seen that big drama in parliament ( Cash case). No body bothered from where this cash come from. what if this type of cash utilize for infrastructure purpose. The people who have this will invest In Infrastructure fund and they will may get some saving bank interest rate and after 7 or ten year they will get all money tax free. But this should be once for all, and person will be prosecuted if not investing in it and caught in future. This is just an idea and can be explore by ICAI or Min of Finance. But definatly it will help infrastructure.
