Rituraj Saikia•10 September 2026

Everything small business owners and proprietors in Assam need to know about turnover limits, documentation, and biometric Aadhaar authentication.
Starting a business in Assam requires a solid foundation in regulatory compliance. Whether you are opening a retail store in Sivasagar, managing a tea trading venture in Jorhat, or offering engineering services in Dibrugarh, understanding your Goods and Services Tax (GST) obligations is essential.
### When is GST Registration Mandatory in Assam?
Under the current GST laws, registration is mandatory when:
1. **Turnover Threshold**: Your aggregate annual turnover exceeds ₹40 Lakhs for exclusive supply of goods (or ₹20 Lakhs in specific special category supply cases).
2. **Service Providers**: Turnover exceeds ₹20 Lakhs per annum.
3. **Interstate Supplies**: Any supply of goods outside the state of Assam requires compulsory GST registration, regardless of turnover.
4. **E-commerce Sellers**: Selling on platforms like Amazon, Flipkart, or Meesho requires GSTIN.
### Key Documents Required
