How to reply against notice received U/s 143(1) in the new portal

Read 143 1 check what is a difference in your amounts and their amount, if there is an error in the TDS amount or TDS amount not considered, maybe an error in your feeding TAN number any other mistake, you will get suggestions in the same order what mismatch.

you have 2 days you can revise ITR under section 139 5 and submit.

in one case person got a refund, which means 143 1 received, he found the mistake, his saving bank income was more and he revised ITR, now he got Demand and he paid 

so no need for rectification under section154 you have 2 days you can revise ITR under section 139 5 and submit.
