Leading industry body, Internet and Mobile Association of India (IAMAI), has shot off letters to the Finance Ministry as well as the GST Council, urging that only Gross Gaming Revenues (GGR) should be considered for levying GST, and that the rate should not be hiked for the online skill gaming sector. It has added that any increase in GST, which is currently at 18 per cent bracket, will adversely impact the growth of this sunrise sector.This submission comes at a time when a Group of Ministers recently arrived at a consensus that a flat 28 per cent GST rate should be levied on online gaming, besides casinos and race courses .
