Jaitley also said the government will soon make furnishing of PAN card details mandatory for cash transactions beyond a certain threshold to check flow of domestic black money.
Jaitley also said that loans given by banks under MUDRA Yojana to entrepreneurs can only be withdrawn from ATMs.
The Finance Minister blamed the "high taxation regime in the past" for encouraging tax evasion and said the present "government's policy is rationalisation of tax structures, taxing at reasonable rates, placing more money in the hands of small earners, encouraging and promoting the use of plastic money by all sections of society and creating deterrence against those who continue to use unaccounted money".

Referring to the declarations made under the compliance window, Jaitley said, "Those who chose to declare between this period would not be prosecuted under the new black money law... These declarants can now sleep well."
"This law will create a deterrent in future against the flight of capital from India," the minister said.
