Respected Sir,

I e-filed my return on the due date of Aug 5th for Prev year 2015-16 and am now realizing I missed putting in some income and may be liable to pay tax than receiving a refund as originally claimed.

In this situation, I am assuming the system should allow me to file a revision and paying up online. Am I right ?

However, I am repeatedly hearing,it can't be done if the assessment has already taken place. I also read somewhere on this forum that I can revise for almost 1 year. Is that correct ?

But what is the assessment tiumeframe then ? Is it a given that the assessment would not happen until Mar 31st anyhow ?

Confused, I am.

Regards
