Under the Goods and Services Tax (GST) law in India, businesses exceeding specific aggregate turnover limits must register within 30 days. For normal category states, the threshold for exclusive suppliers of goods is ₹40 Lakhs, while for service providers and mixed suppliers it is ₹20 Lakhs. In designated Special Category States (such as Manipur, Mizoram, Nagaland, and Tripura), the threshold is ₹10 Lakhs. Crucially, Section 24 of the CGST Act mandates compulsory registration irrespective of turnover for inter-state suppliers, e-commerce sellers, and reverse charge payers.
Key Statutory Takeaways
- Standard threshold is ₹40 Lakhs for exclusive suppliers of goods in normal states (Notification No. 10/2019-Central Tax).
- Threshold for service providers is uniformly ₹20 Lakhs across all normal states, and ₹10 Lakhs in specified special category states.
- Aggregate turnover encompasses all taxable, exempt, export, and inter-state supplies across all business verticals sharing the same PAN.
- Section 24 overrides Section 22: inter-state suppliers of goods and e-commerce operators must obtain GST registration with ₹0 turnover.
- Operating without mandatory registration invites penalty of 100% of tax due or ₹10,000, whichever is higher, under Section 122.

1. State-Wise GST Registration Thresholds
GST registration limits are determined by two legal dimensions: the nature of commercial supply (goods vs services) and the statutory state classification (Normal vs Special Category):
| Category of States | Suppliers of Goods Only | Suppliers of Services & Mixed |
|---|---|---|
| Normal States (Maharashtra, Delhi, Karnataka, Gujarat, UP, etc.) | ₹40 Lakhs | ₹20 Lakhs |
| Special States - Tier 1 (Manipur, Mizoram, Nagaland, Tripura) | ₹10 Lakhs | ₹10 Lakhs |
| Special States - Tier 2 (Arunachal, Meghalaya, Sikkim, Uttarakhand, Puducherry, Telangana) | ₹20 Lakhs | ₹20 Lakhs |
| Jammu & Kashmir, Himachal Pradesh, Assam | ₹40 Lakhs (Goods) | ₹20 Lakhs (Services) |

2. How Aggregate Turnover is Calculated
Under Section 2(6) of the CGST Act, aggregate turnover is calculated on an all-India PAN basis. It includes all outward supplies made by the business entity across all branches:
- Included: All taxable supplies of goods and services.
- Included: Exempt supplies, nil-rated supplies, and non-taxable supplies.
- Included: Export of goods and export of services.
- Included: Inter-state supplies between distinct persons (branches with same PAN).
- Excluded: Value of inward supplies on which tax is payable under Reverse Charge Mechanism (RCM).
- Excluded: Central Tax (CGST), State Tax (SGST), Integrated Tax (IGST), and Compensation Cess.
3. Section 24 Compulsory Registration Triggers
Under Section 24 of the CGST Act, certain categories of commercial operators are statutorily required to obtain GST registration irrespective of their annual aggregate turnover:
- Persons making any inter-state taxable supply of goods.
- Casual taxable persons making taxable supply in an exhibition or temporary trade fair.
- Persons required to pay tax under Reverse Charge Mechanism (RCM) under Section 9(3) or 9(4).
- Non-resident taxable persons making taxable supply in India.
- E-commerce operators required to collect TCS under Section 52.
- Suppliers of goods through an e-commerce platform (subject to intra-state threshold exemptions).
- Input Service Distributors (ISD) distributing common input tax credits across multi-state branches.

- Seamless Input Tax Credit (ITC): Enables passing input tax credit to B2B enterprise clients, preventing your invoices from becoming an unrecoverable cost component for buyers.
- Inter-State B2B Expansion: Permits inter-state sale of goods and seamless participation in corporate and government procurement tenders.
- Enhanced Banking Credibility: A verified GSTIN strengthens business credit profile for securing working capital lines, letters of credit, and merchant payment gateways.
