Respected to all,
My Aggregate Turnover is below than 2 crore & I want to file my GSTR-9 for F.y. 17-18 & F.y. 18-19.

So is it mandatory for me to file GSTR-9 ?
Because there is some confusion in 37th Press Release of GST. Where mention some relaxation for MSME taxpayers but in Circular 124/2019 CGST Act no any MSME word used for relaxation.

Please clear this relief.
