Singhvi meanwhile remained unavailable for comments.
"The Income Tax Settlement Commission has come up with shocking revelations. This is a classic expression of how black money is being generated in India, and that too by non-other than tall leaders of the Congress," BJP spokesperson Sambit Patra said.
"The settlement commission has added about Rs.92 crore to the professional income of Singhvi over a period of three years. Why was he not declaring this income?" he questioned.
"He has no document to back these expenses. He says that the documents were eaten away by termites. Sadly those who destroyed the economy of the country acting as corrupt termites are trying to shift the blame to the poor real termites," he said.
According to a media report, the settlement commission has added over Rs.91.95 crore to Singhvi's declared professional income over a three-year period and slapped a penalty of Rs.56.67 crore.
Singhvi, according to the report, told the commission that a termite attack on the premises of his chartered accountant in December 2012 destroyed all records and expense vouchers.
