GST (Goods and Services Tax) registration is mandatory if your annual turnover exceeds Rs 40 lakh (Rs 20 lakh for services, Rs 10 lakh for special category states like Manipur, Mizoram, Nagaland, and Tripura). Even if you're below the threshold, voluntary registration unlocks benefits like input tax credit and credibility with larger clients.
Thresholds as per GST Council's 32nd meeting (Jan 2019), confirmed unchanged as of Feb 2026. Official portal: gst.gov.in
Who Needs GST Registration?
Key takeaway
Goods sellers
Service providers
E-commerce sellers
Interstate sellers
E-Commerce Exception (Narrow)
Since October 2023, small sellers making only intra-state supplies through platforms may be exempt if below the threshold (Notification 34/2023-CT). But most e-commerce sellers ship nationally and still need registration. Even below the threshold, voluntary registration unlocks input tax credit and credibility with larger clients.
