S. 143(3): Assessment – Method of accounting -Undisclosed income – Admission by a letter without-prejudice offer cannot be treated as admission of non-disclosure or as an unconditional offer to pay tax. Also, the disclosure is by the USA Co and not by the assessee- It is not the case of the Dept that the amount has been received in the accounts of the assessee or spent for and on behalf of the assessee so as to be treated as undisclosed income of the assessee.
