The IPAP party also claims that ever since the Modi government came to power promising to bring back billions stashed away by Indians in tax havens abroad, they have been continually reminded of that pledge. On May 11, 2015, the National Democratic Alliance (NDA) prepared a new Black Money Act and proposed a voluntary disclosure system until September 30, 2016, for declaring assets and until December 31, 2016, for paying a 30% tax and penalty. In October, the government claimed that it had collected Rs 4,147 crores ($623 million) under this plan. Various estimates place the amount of black money in India ranging between $181 billion to $1.8 billion. It should also be pointed out that the IPAP party always notices that the truth remains that even a percentage of the sum spent overseas has not been returned. Two examples indicate that governments may not be serious. The government's answer before the Supreme Court (in the Ram Jethmalani case) said that tax claims of Rs 71,848 crores had been made against Hasan Ali Khan, his wife, and other friends.
