Sir
I provide service of renting immovable property to bank. My turnover is 15lakh and in pre-gst period I was registered under service tax.

I migrated and taken provisional registration in GST, but as turnover limit in GST is 20 lakh for registration, now I want to surrender my GST Reg.No.

Whats the procedure to surrender the no. and where to get form GST-REG-16?

Dear Experts,

Should we deposit GST under RCM u/s 9(4) in the m/o Sep-2017 also.

One more query is that we are depositing IGST today by 2 days late. So in which
head we have to deposit these 2 days interest i.e. in IGST or CGST & SGST.

Please advise.

I am trying to submit GSTR1 for August and also for September but there is "Counterparty Error" for both. In news I am reading that all are filing GSTR3B but I am stuck at GSTR1. Please help me to understand the entire process.

I can't file GSTR 3B for August, because of error showing "cash ledger not having sufficient balance to set off" even if cash ledger sufficient balance to set off the penalty and input tax credit. For this reason I'm also not able to file GSTR 3B for the month of September And my penalty goes up everyday What can I do. Please suggest me.
