Hi,
ITR 1 sahaj is meant for salaried and pensioners. If you show some details in other revenue, like bank interest, you have to fill the page 2 of the form with bank details in which you have account.
The provision is there for only two bank accounts. It is not surprise, that one has FD, on more than 2 banks. If it is not furnished, then there is concealment of information clause to penalize. But there is no provision to enter more than 2 banks in the Return. Could you kindly say how to do
