1. Who Must Register for GST in Nagapattinam?

As per the GST Act, 2017, the following businesses in Nagapattinam 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: Nagapattinam 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

Even below the threshold, voluntary GST registration is advisable for B2B businesses in Nagapattinam — unregistered suppliers cannot issue tax invoices, which blocks buyers' ITC claims and frequently costs businesses their largest client contracts.
