Assessee filed income tax return twice for the assessment year 2008-09,
The first one was physically filed and the second one was for the assessment year 2009-10, but while e-filing the return the assessee wrongly selected "A.Y. 2008-09" instead of "A.Y. 2009-10". The assessee received intimation u/s 143 (1)and while calculating the original return was not considered at all and the calculations were done on the basis of the second return resulting in tax liability.
What should be done?
