TCS Q4 Filing offline without using DSC

Yes, late fee u/s 234E (Rs.200/day or liability whichever is less) applicable, as no extension has been provided so far. Also check the possibility of filing the same in TIN-FC if you are unable to file it online.

Agree with poornima

In a state of lockdown its unlikely that a facilitation center will be open. also there is a fear of getting caught by police. cbdt must extend the due date, there is no other way. else we might have to show our protest by not filing late fee and raise dispute in appellate forums.
someone must file a writ in supreme court if cbdt does not extend the due date.
