Income-tax officials expect to unearth evasion worth several crores of rupees by promoters of Motia Group and its associates Subhash Mangat and Company due to unaccounted transactions and undervaluing of certain properties in their tax declarations.

I-T sleuths have already detected evasion worth Rs 10.50 crore from the promoters, even as two bank lockers of the construction group are yet to be looked into.

Documents recovered from about a dozen lockers have been scrutinized, said a senior functionary of the office of income-tax director general (investigation).

Officials said there were certain deals, which had no mention in the group?s account books. They added that there were some properties that the group?s officials had undervalued in their tax declarations. ?We have sent the documents to evaluation wing to find the exact amount of tax evasion,? the officer added.

The raids on 20 premises connected with Motia Group and its associates were conducted on February 27. About 100 I-T sleuths headed by deputy commissioner (income tax) Abhishek Garg carried them out.

Other than the residential premises of promoters Pawan Bansal, Krishan Goyal, Kewal Bansal, LC Mittal, HR Mittal, Ramesh Mittal and Sat Pal Goyal, the sleuths also raided business premises at Zirakpur, Baddi, Dhakoli and Nabha.

Premises connected with their business associates Subhash Chand Chopra, Mangat Rai Babuta, Surender Babuta and Yogesh Chopra were also raided.

The official stated that the final evaluation report of documents under the department?s scrutiny could set a new record of tax evasion detection in the region.
