Turnover Limits, Documents & GSTIN Issuance Answers

Clear answers regarding mandatory turnover thresholds, virtual office registrations, Aadhaar biometric verification, and bank linking rules.

For suppliers of goods, GST registration is mandatory when annual aggregate turnover exceeds ₹40 Lakhs (or ₹20 Lakhs in Special Category States). For service providers, the threshold is ₹20 Lakhs (or ₹10 Lakhs in Special Category States). However, registration is mandatory regardless of turnover for businesses engaged in interstate sales or e-commerce.

You will need the PAN card of the entity and directors/partners, Certificate of Incorporation or Partnership Deed, Aadhaar cards of authorized signatories, passport-size photographs, proof of principal place of business (electricity bill or municipal property tax receipt not older than 2 months, rent agreement, and landlord NOC), and a cancelled cheque or bank statement.

Yes. A residential address can be registered as the Principal Place of Business, provided you have a valid electricity bill not older than 2 months, a No-Objection Certificate (NOC) signed by the property owner, and a formal rent agreement if the premises are rented.

If the applicant opts for biometric Aadhaar authentication and the officer raises no clarification queries, the registration certificate (Form GST REG-06) is typically approved and issued within 3 to 5 business days. If a clarification notice (REG-03) is issued, it takes approximately 7 business days following submission of the defense reply.

Aadhaar authentication is an automated biometric identity verification mechanism on the GST portal. When promoters authenticate their Aadhaar via OTP or at a designated GST Suvidha Kendra, the application is processed on a fast-track basis without requiring physical site verification by a tax officer prior to registration grant.

No. Under the GST structure, registration is state-specific. The first two digits of your 15-digit GSTIN represent the state code (e.g., 33 for Tamil Nadu, 27 for Maharashtra). If your business operates physical offices, warehouses, or fulfillment centers across multiple states, you must obtain a separate GSTIN for each state.

Rule 10A of the CGST Rules mandates that every newly registered taxpayer must submit their corporate bank account details (account number, IFSC, and cancelled cheque) on the GST portal within 30 days of registration grant or before filing the first GSTR-1/IFF, whichever is earlier. Failing to do so triggers automatic suspension of the GSTIN.

Form REG-03 is issued when an officer seeks additional evidence—such as clearer address proof, municipal tax receipts, or specific HSN descriptions. You have 7 working days to reply in Form REG-04. Our Chartered Accountants draft and submit the legal clarification dossier within 24 hours to secure swift approval.

Yes. Any business can apply for voluntary GST registration. Voluntary registration allows you to issue valid tax invoices, claim Input Tax Credit on capital goods and business expenditures, register on corporate vendor portals, and sell products through national e-commerce platforms.

Submit an inquiry through our consultation desk. Our tax team will review your business address documentation, verify promoter KYC credentials, map your primary HSN/SAC codes, and submit your Form GST REG-01 application within 24 hours.
