As per The scheme, but now if for eg, if I have some undisclosed creditors form the AY 2008-09(eg) and I have received notice (2014-15) in which I need to give explanation for such creditors (the info wrt such creditors is gathered by the IT department), and now if i wish to file declaration for such creditors than from which date should I consider such undisclosed cr. in my declaration ie. from the date they are standing undisclosed(here 2008-09) or the date of receipt of notice(2014-15)
