Dear Sir!!
You have indeed posted a very interesting question!
As per the explanation brought into force by the Finance Act, 2007 below Section 9 of the Income Tax Act, 1961, any income by way of interest, royalty or fees for technical services would be deemed to accrue or arise in India, irespective of the fact that whether there is any territorial nexus for such income with India or whether the services are rendered and utilised in a business in India.
The above amendment has nullify a few contrary court judgements. The source rule applicable for income deemed to accrue or arise in India and provided in Section 9(v), (vi) and (vii) are suffixed by the above explanation.
Thus in the instant case, the income received by the Indian branch of the foregn bank, is in no doubt, an indian income liable for tax in India.
As far as TDS is concerned, the services availed by the client being of a professional nature involving proper financial appraisal, verifying the credit worthiness, asset particulars, securities provided, etc, it qualifies to be a professional service liable for TDS under Section 194J of the Income Tax Act, 1961.
It is hoped that the opinion provided by me, is correct.
Do post your comments!
Good bye!! Cheers!!
