Non payment of gst by suppliers

Legally you cannot take the ITC as per clause c of sub-section 2 of section 16. Ask the supplier to make the payment or else it will be disallowed in future and you may have to make the payment along with interest.

just ask supplier to upload the invoice and file returns on time so that each and every input is reflected in gstr 2A so that you can see in them

make reconciliation of suppliers time to time who has uploaded and who has not file returns so that when govt comes out with single return after 6 months you would not have any problems

hope u got my point

thanks and regards
