For games of skill (Rummy, Fantasy sports): Previously 18% GST on platform fee. Now 28% on full deposit value. This massively increased the effective cost to players, many platforms saw volume drop significantly. As a player: You don't pay GST directly. The platform builds it into their pricing. But your effective cost per game is now 28% higher. When comparing platforms, check if the displayed amount is pre-GST or post-GST. For gaming companies (if you operate one): Mandatory GST registration regardless of turnover. Monthly GSTR-3B with 28% GST on all deposits.
