For the financial year 2018-19, there is no turnover limit for filing the GSTR 9 annual return. However, the GSTR 9C, which is a reconciliation statement, has a turnover threshold of Rs. 5 crores for the same period. Therefore, if your taxable turnover was below Rs. 5 crores, you are required to file GSTR 9 but not GSTR 9C.
