I have received a notification under section 139 saying that the income tax office has information through AIR that I have entered into a high value financial transaction without quoting my PAN. They have asked me to furnish my PAN. That is not an issue as I can easily do that. However, the letter has my name spelt wrong and even the address is wrong and differs from what I have on my PAN and on the income tax records. It reached me because the postman knows my name. Also the letter is dated December 2012 and it has got to me now. So I am a little suspicious of the letter. How can I ascertain whether its a genuine letter because I have quoted my PAN in all my transactions and filed my return accordingly.
