1. Who Must Register for GST in Thoothukudi?

As per the GST Act, 2017, the following businesses in Thoothukudi must mandatorily register for GST:

• Turnover threshold: Annual turnover above ₹40 lakh for goods suppliers; above ₹20 lakh for service providers in Tamil Nadu
• Interstate suppliers: Thoothukudi businesses supplying goods or services to other states — regardless of turnover
• E-commerce sellers: All sellers on Amazon, Flipkart, Meesho, or any online marketplace — mandatory regardless of annual turnover
• Reverse Charge Mechanism (RCM): Businesses receiving specified supplies on which they must pay GST under RCM
• Importers and exporters: Any Thoothukudi business engaged in cross-border trade of goods or services
