GST Registration in Guwahati — Complete Guide for Assam Businesses

The Gateway to Northeast India — Guwahati is the commercial hub for all seven northeastern states, a major tea trading centre, and home to India's oldest oil refinery. If you run a business in Guwahati, Assam — whether you are a trader in Fancy Bazar (Commercial), a professional near Ganeshguri, or a service provider anywhere in the city — GST Registration is the essential first step towards legal compliance, Input Tax Credit benefits, and business credibility. Our CA team at TaxAMC provides expert, fast, and affordable GST Registration services across Guwahati and surrounding areas.

1. Who Must Register for GST in Guwahati?

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

• Turnover threshold: Annual turnover above ₹40 lakh for goods suppliers; above ₹20 lakh for service providers in Assam
• Interstate suppliers: Guwahati 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 Guwahati business engaged in cross-border trade of goods or services
• Casual taxable persons: Those making occasional taxable supplies in or from Guwahati
• Agents of registered suppliers operating in Guwahati

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