GST registration enforcement for service-sector traders through data-based identification, turnover estimation, and suo motu registration action. Increase in GST registrations among service-sector traders by identifying unregistered persons liable to registration, including earlier service-tax registrants whose registrations were cancelled. Officers must organise workshops, collect information from electricity, labour, municipal and online sources, estimate turnover of restaurants, beauty parlours, gyms, coaching institutes, hotels and similar businesses, and take action for registration where turnover exceeds the prescribed threshold under section 25(8) and rule 16. Weekly reporting of newly registered traders is required.
