Any further action necessary after filing rectification?

If you have received mail about rectification being processed, no need to do any thing.

Otherwise check the status..

Dear sir,

Thank you for the answer. Just one more question sir, if after reprocessing my return if CPC again makes a demand, will I get another 30 days to respond or is the demand "final" at that point?

If there is any change in tax demand, you will get time extended, otherwise this will be the final.

Generally demand will disappear in the new website ,once you file rectification.So wait till you get rectification order u/s 154.You can take time no issue if you disagree for demand. If rectification is doesn't work then try for revised return.

Since challans are updated in 26AS there won't be any issue.The demand may get nullified

Dear sir,

Thank you for the response, it means a lot to me.

If I revise the return now (even though rectification is in process) will that cancel the demand and give me a fresh 30 days?

The thing is, I have paid all my taxes but the challan is not matching due to a software issue.

Dear Eswar sir,

Yes you are 100% correct, The demand has disappeared after filing for rectification. I was very confused.

If I am understanding you correctly,

1. I wait for rectification order u/s 154. If no demand there, then no issue

2. but if there is more demand in rectification order u/s 154 then I can still disagree to the demand within 30 days of this rectification order. Is this correct?

My problem is that even though my challan have appeared on 26AS the problem is the software has changed my challan number during return filing. It has removed the first number from the challan number if the first number is a 0.

You have to wait till you get order u/s154 & you may revise afterwards..

Even in rectification there will be an option of, rectification for tax credit mismatch only .You may get options to add challans.

Try to do the online rectification .You can also update the challan number in your software & do rectification through e filing portal
