Titled "Keep Away from Benami Transactions", it described black money as a "crime against humanity" and urged "conscientious citizens to help the government in eradicating it".

"Benamidar (in whose name benami proper is standing), beneficiary (who actually paid consideration) and persons who abet and induce benami transactions are prosecutable and may face rigorous imprisonment upto 7 years besides being liable to pay fine upto 25 per cent of fair market value of benami property," the I-T advertisement said.

The tax department attached benami assets worth Rs 1,833 crore across the country, issued 517 notices and made 541 attachments, from November 1, 2016 to October 2017.

The department started initiating action under the new Benami Transactions (Prohibition) Amendment Act, 2016 from November 1, 2016.

The advertisement added that "persons who furnish false information to authorities under Prohibition of Benami Property Transactions Act, 2016, are prosecutable and may be imprisoned upto 5 years besides being liable to pay fine upto 10 per cent of fair market value of benami property".

It added that benami property "may be attached and confiscated by the government" and that this action will be in in addition to prosecution under the Income Tax Act of 1961 for tax evasion charges.
