Input credit

no, if seller charge GST in bill then seller is liable to pay GST. you claim such GST in your GSTR .

Its my personal opinion, if anybody have different view then views are welcome. thanks. Disclaimer: its not Professional Advice.

you can take claim provisionally if that is not showing in your GSTR 2A. however inform your supplier also that it is not showing.

Yes...
You can take ITC. Also your seller not file his GSTR 1 You ll consider with Your supplier and force to file his return and Payment...

yes act allow u to take input on self assess but if Ur supplier not deposit the gst means he has not file the return so in that case u have to reverse Ur ITC with interest .
so plz ask Ur supplier to deposit the gst file the return

U/s 38(7), registered person should be paid taxes to Government which is collected from customer. file the returns.
monthly he has to file GSTR 3B and upload outward supplies every omth. hence no liability on buyer. but make ensure I'm GSTR 2A such transaction.
In case of fails to pay taxes, he will get interest and huge penalties.

if anything wrong or different opinion. let it correct.
