The accounts in various bank branches in Uttar Pradesh were attached last night.
The provisional attachment action has been carried out to "recover outstanding tax demands", understood to be about Rs 85 crore, the officials said.
Three bank accounts of the group were attached in January last year by the department, they said.
The Kanpur-based group is being probed by the CBI and the Enforcement Directorate in connection with an alleged bank loan fraud of Rs 3,695 crore, given by a consortium of seven banks.
The CBI had registered a criminal case against Rotomac Global Pvt Limited, its Director Vikram Kothari, his wife Sadhana Kothari and son Rahul Kothari and unidentified bank officials on a complaint received from Bank of Baroda and conducted raids against them on Monday.
The principal amount involved was Rs 2,919 crore. The ED subsequently registered a money laundering case against them.
The ED will probe if the allegedly defrauded bank funds were laundered and these proceeds of crime subsequently used by the accused to create illegal assets and black money.
This is the second major financial scam to break out after the sensational Rs 11,400 crore fraud allegedly committed by billionaire jewellery designer Nirav Modi and his uncle Mehul Choksi, who is a promoter of Gitanjali group of companies.
Both left the country before the Punjab National Bank realised the seriousness of the alleged crime.
