Terms & Conditions

Time limit

GST registration application will be approved within a time limit of 7–21 working days, and in rare situations it may take up to 50 days when the application is not authenticated using Aadhaar validation.

Generation of ARN number

Time limit for approval of GST registration is counted from the date of generation of the ARN number, which is generated on selection of verification procedures.

Previous defaults

Where a previous GST registration number is not closed properly with the same PAN or associated enterprises, the GST registration will be approved only after clearing the pending defaults. In case of non-disclosure of these facts, refund of professional fees will not be granted after submission of the GST registration application.

Additional documents

Although the GST act specifies a list of documents for GST registration, in some cases the GST officer may require additional documents for approval; it is the responsibility of the client to arrange the same.

Additional fees and other charges

In rare cases where there is a requirement to visit the department, visiting charges and other charges are applicable in addition to the professional fees to apply for GST registration.

Steps in GST registration

1

GST registration consultation

As a commitment towards reliability, a discussion with the client is held to confirm whether GST registration is really required legally or in practical terms — saving clients from unnecessary compliance.

2

Documentation

Clients are advised on the documents required for their application, with suggestions for preparing valid, appropriate documents for fast approval.

3

Online application filing

The GST registration application is submitted with the necessary documents and relevant details on the online GST portal.

4

Aadhaar authentication

For fast approval without physical verification of the business premises, the application should be verified using an OTP sent to the Aadhaar-linked number.

5

ARN number generation

The Application Reference Number tracks the status of the application. The approval time limit is counted from the date the ARN is generated.

6

Tracking and approval

After the ARN is generated, the application status is tracked. Once approved, the GST certificate and further guidance are provided.

What Should I Know Before Getting GST Registration?

Mandatory if turnover exceeds the threshold

Mandatory once turnover exceeds ₹40 lakhs for traders, or ₹20 lakhs for service providers. Apply within 30 days in Form GST REG-01 via the online portal.

No turnover limit for certain businesses

Required for interstate sales, imports and exports, or trading under someone else's brand name, regardless of turnover.

All rules apply to voluntary registration

Once approved, a voluntary registrant follows every rule a regular dealer does — all returns and forms by their due dates.

GST composition scheme

For small dealers up to ₹1.5 crore (goods) or ₹50 lakh (services): a fixed tax rate, no input credit. Must be opted for at registration, not after.

Cancellation on the taxpayer's application

When a GST number is no longer required, apply for cancellation and file Form GSTR-10 in time to avoid issues with any future registration.

Automatic or manual approval

Eligible applicants may use the simplified route under Rule 14A, Form GST REG-01, with electronic approval within three working days when portal checks succeed and Aadhaar is authenticated. GST Council reference.

GST Registration FAQs

Select a question to read the answer.

What is the validity of a GST registration certificate?
A GST registration certificate is valid as long as it is not cancelled by the GST officer or on an application by the taxpayer.
Can I open a branch with the existing GST number of my head office?
Yes. An additional place of business, such as a branch within the same state, should be added to the existing registration through an amendment application.
Is physical verification mandatory for GST registration?
Not for every application. If Aadhaar validation fails or is not chosen, an inspection of the business premises may be assigned, and the GST number allotted only after verification.
Do I need a GST number for exempted goods or services?
GST registration is based on the value of taxable supply on an all-India basis. It can still apply even when a particular state only trades exempted goods.
Can I use a single GST number all over India?
No. A separate registration is needed in each state with a principal place of business. One state's registration covers its head office and branches only.
