About GST Registration

GST registration gives your business a 15-digit GSTIN, allowing you to collect GST, claim input tax credit and supply to other states and e-commerce platforms. It is mandatory once your aggregate turnover crosses the threshold for your state and activity, and from the first sale for inter-state suppliers of goods, e-commerce sellers and certain other categories. We file Form GST REG-01, handle Aadhaar authentication and respond to any officer queries.

Frequently Asked Questions

When is GST registration mandatory?↓

When aggregate turnover crosses ₹40 lakh for suppliers of goods or ₹20 lakh for suppliers of services in most states (lower limits apply in some special category states). It is also mandatory, regardless of turnover, for inter-state supply of goods, sellers on e-commerce platforms and those liable under reverse charge.

Can I register voluntarily below the threshold?↓

Yes. Many businesses register voluntarily to claim input tax credit or to work with clients who insist on a GSTIN. Once registered, you must file returns even if there are no sales.

Can I get GST registration at my home address?↓

Yes, a residential address can be the principal place of business if you provide valid ownership or rent proof and a utility bill.

Why might the officer ask for clarification?↓

Officers commonly query unclear address proofs, mismatched names or missing authorisations. We reply within the time allowed, but the final approval is at the officer's discretion.

What happens after registration?↓

You must issue GST-compliant invoices and file GSTR-1 and GSTR-3B monthly, or quarterly under QRMP if eligible, along with an annual return where applicable.

What is biometric authentication in GST registration?↓

In some states, applicants flagged by the system must visit a GST Suvidha Kendra for biometric and photo verification before the application is processed. We tell you if this applies to you.
