Dear Experts
1. The Turnover in Financial Year 2017-2018 is less than Rs. 2.00 Cr as per Audited Balance sheet. Whether I should file GSTR 9 for the financial year 2017-2018?
2. If Inocme from Interest on FDR (it was not included in Trading or Profit and loss account in f/y 2017-2018 but included in capital account for income tax purpose) should be added in total turnover for the purpose of filling of GSTR 9. If yes then my total turnover in f/y 2017-18 exceeds Rs. 2.00 Cr and I have to file GSTR 9
Please guide me with a better solution
