Undisclosed income transfer to other person's AO triggers block assessment and fixes abatement reference to receipt date.
When an Assessing Officer is satisfied that seized money, assets, books, documents or any information therein pertain to a person other than the person searched, those materials must be handed to the Assessing Officer having jurisdiction over that other person, who shall proceed under section 294 and apply the block assessment provisions; for abatement under section 292 the reference date for the other person is the date the receiving AO obtains the seized materials or information.
