I raised some invoice to my client and it is still pending for last three months. Meanwhile, my contract with client has been revoked and client has not yet paid my dues. I did not pay the GST amount related to the invoices, I thought that there is no more business from that client, so I just ignored gst payment & return filing.
Now I came to know that I have been charged penalty for non filing GST return and actual amount has been increasing every month. I wanted to surrender my GST no. but heard that it will not help me and I will be black listed in CIVIL and I wont be abale to open a new company with my PAN no.
Plz some one let me know the correct consequences if I default payment of GST in my case.
