Bank account no

You should provide the Bank account number of the assessee. 

No.account must belong to the assessee whose return is being filed.

it is mandatory for providing assessee acount no ?

In case i shown in my ITR Any Other person (like Relatives or friends) bank Account No In My ITR, Then may i get refund From Dept? it's possible or not ? pls tell me sir its urgent....

When refund is sent to a bank account. The Name , PAN No  of assesse should match with account of  Bank - other wise the refund will be reversed. 

STRICTLY  ACCOUNT NO SHOULD BELONG TO ASSESSEE ONLY.

no, you have to provide bank account no of urs.

If the refund amount pertains to you, then why there is a need to show some other persons Bank Account details ? Isn't that money which the government has received in the form of TDS or otherwise, not belonging to you?
