1. Aggregate Turnover Framework
Under the Central Goods and Services Tax (CGST) Act, 2017, the requirement to register for GST is primarily anchored in the concept of 'Aggregate Turnover'. Aggregate turnover is computed on an all-India basis across all entities registered under the same Permanent Account Number (PAN).
Aggregate turnover includes taxable supplies, exempt supplies, exports of goods and services, and inter-state supplies, but excludes inward supplies liable to Reverse Charge Mechanism (RCM) and taxes paid under GST law.
2. State-Wise Threshold Matrix
| Category of State | Goods Only Supplier | Services / Mixed Supplier |
|---|---|---|
| Standard States (e.g. Maharashtra, Delhi, Karnataka, Tamil Nadu, UP) | ₹40 Lakhs | ₹20 Lakhs |
| Special Category States - Tier 1 (Manipur, Mizoram, Nagaland, Tripura) | ₹10 Lakhs | ₹10 Lakhs |
| Special Category States - Tier 2 (Arunachal, Meghalaya, Sikkim, Uttarakhand, Puducherry, Telangana) | ₹20 Lakhs | ₹20 Lakhs |
3. Compulsory Registration Scenarios (Section 24)
Section 24 of the CGST Act prescribes specific situations where registration is legally mandatory regardless of whether turnover reaches the threshold limit:
- Inter-state suppliers of goods (supplying from one Indian state to another)
- Casual taxable persons making taxable supplies
- Persons liable to pay tax under Reverse Charge Mechanism (RCM)
- E-commerce operators and electronic marketplace sellers
- Non-Resident Taxable Persons making supplies in India
- Input Service Distributors (ISD)
- Persons supplying online information and database access or retrieval (OIDAR) services from outside India to non-taxable online recipients in India
4. Required Documentation Checklist
Preparing clean, legible PDF/JPEG documents is the most effective safeguard against verification queries (Form GST REG-03) from tax officers:
- PAN Card of the applicant entity and all authorized promoters
- Proof of Business Constitution (Partnership deed, Certificate of Incorporation, MOA & AOA)
- Principal Place of Business proof (Electricity bill not older than 2 months + Rent Agreement + Landlord NOC)
- Bank account documentation (Cancelled bank cheque bearing entity/promoter name, or updated bank statement)
- Aadhaar card of authorized signatory for digital biometric / OTP authentication
