Overview
Goods and Services Tax (GST) registration gives a business its GSTIN, lets it collect GST and claim input tax credit, and is required to sell to many business customers and on most online marketplaces. Registration is applied for online on the GST portal in Form GST REG-01, with Aadhaar authentication of the promoters and authorised signatory.
Registration is compulsory once aggregate turnover crosses the threshold (generally ₹40 lakh for businesses supplying only goods in most states, ₹20 lakh for services, and lower limits in some special category states) and, regardless of turnover, in cases the law lists, such as most inter-state supplies of goods, casual taxable persons and many sellers on e-commerce platforms. Smaller businesses can also register voluntarily.
Our team checks which registration type fits (regular, composition or the simplified scheme), prepares the application and documents, helps you complete Aadhaar authentication, and answers any clarification the GST officer raises.
Who needs it
- Businesses whose turnover crosses the GST threshold for their state and type of supply
- Sellers supplying goods to other states or selling through e-commerce platforms
- Businesses that want to claim input tax credit or whose customers insist on a GST invoice
- Exporters of goods or services
Documents required

How it works
- 1
Check what you need
We look at your turnover, the places you supply to and how you sell, and tell you whether registration is mandatory and which scheme suits you.
- 2
Part A: verify PAN, mobile and email
The application starts on the GST portal with the business PAN and OTP verification of the authorised signatory's mobile and email; a temporary reference number is generated.
- 3
Part B: full application
We fill in business details, promoters, places of business, goods and services (HSN/SAC codes) and bank details, and upload the documents.
- 4
Aadhaar authentication
Promoters and the authorised signatory complete Aadhaar authentication through the link sent to them. Skipping it can mean a site visit and a longer wait.
- 5
Officer review and queries
The GST officer examines the application. If they issue a notice asking for clarification, we prepare the reply within the time allowed.
- 6
GSTIN issued
On approval the registration certificate (Form GST REG-06) is available on the portal with your GSTIN.
Typical timeline
Under the CGST Rules, the officer generally has 7 working days to approve a complete application or raise a query. Where Aadhaar authentication isn't done, or the department decides to verify the premises physically, this can extend to 30 days. A clarification notice must be answered within 7 working days. Since 1 November 2025, an optional simplified scheme grants registration within 3 working days after Aadhaar authentication to applicants who expect their monthly output tax on supplies to registered persons to stay within ₹2.5 lakh.
