Hi Dhanwanti ,
Please do not reply to this Letter without verifying that whether such Officer is present at the given address or not.
As this is the Fake letter sent by the some fraudsters. If you see carefully, This letter is printout letter and does not bear any original stamp and second when you verify the office address of income tax office and place of dispatch of letter is different.
Also you can see that the letter does not provide the PAN number of assessee. simple question here is how did the person sending letter come to know that client has not filed ITR , these fraudsters are trying to extract details.
As with this details , person can reset the password of Income Tax.
