GST Registration Overview
The registration of an assessee or "taxable person" is the first step in any tax law. It is a key requirement for identifying the business for tax purposes and ensuring compliance with regulations.
The CGST Act mandates that every supplier making taxable supplies must register. Any supplier whose total turnover exceeds ₹20 lakh in a financial year is required to register. However, for businesses operating in certain states—namely Himachal Pradesh, Uttarakhand, Manipur, Arunachal Pradesh, Assam, Jammu & Kashmir, Meghalaya, Mizoram, Nagaland, Sikkim, and Tripura—the registration threshold is reduced to ₹10 lakh.
When calculating the turnover for registration, the supply of goods by a registered job-worker, after completing job-work, is treated as the supply of goods by the "principal" and should not be included in the job-worker’s aggregate turnover for registration purposes.

- Under GST, businesses must register in each state where they make taxable sales. If a person sells taxable goods or services in multiple states, they need to register separately in each state once their total earnings exceed the threshold limit, taking into account sales from all states.
- If a person makes taxable sales from different locations within the same state, only one registration is needed for that state. However, if they have different business verticals, they can register multiple times within that state.
- When registering, a taxpayer must choose one location as the principal place of business and list all other locations as additional places of business.
- The registration application must be filed within 30 days from when the requirement to register arises.
- A business vertical is a specific part of a business that provides different goods or services. Each vertical has its own risks and returns compared to others. To identify a business vertical, factors such as the type of goods or services, production methods, customer types, distribution channels, and the regulatory environment (like banking, insurance, or public utilities) are taken into account.
- Businesses that are already registered under Excise, VAT, or Service Tax cannot claim exemptions from the threshold limit. They must switch to GST and obtain provisional registration from GSTN before the set date, even if their earnings are below the threshold limit.
- These businesses can choose not to get provisional registration if their sales do not fall under GST or if they are below the threshold limit.

Aggregate turnover refers to the total value of all taxable supplies, exempt supplies, exports of goods or services, and inter-state supplies made by a person with the same Permanent Account Number (PAN), calculated on an all-India basis. However, the following are excluded from this calculation:
- Central Tax (CGST)
- State Tax (SGST)
- Union Territory Tax (UTGST)
- Integrated Tax (IGST)
- Cess
Additionally, the value of inward supplies on which tax is payable under reverse charge is also excluded from the aggregate turnover.
A Special Economic Zone (SEZ) unit or developer must apply for registration separately, treating it as a distinct business vertical from other units located outside the SEZ.


A casual taxable person or a non-resident taxable person must apply for registration at least 5 days before starting their business activities. A casual taxable person refers to someone who occasionally makes taxable supplies of goods or services (or both) in a state or Union Territory where they do not have a fixed place of business. A non-resident taxable person is someone who occasionally conducts taxable transactions involving the supply of goods or services (or both) for business purposes but does not have a fixed place of business or residence in India.

Amendment to Registration
There are several situations where the registration issued by the competent authority needs to be amended to reflect real-time changes. In such cases, every registered taxable person must inform any changes in the information provided at the time of registration within 15 days of such changes.
The proper officer cannot reject the request for amendment without giving a reasonable opportunity to be heard, following the principles of natural justice.
Cancellation of Registration
A granted registration can be cancelled by the proper officer either on their own initiative or at the request of the registered person under the following circumstances:
- If the business is discontinued, fully transferred for any reason (including the death of the proprietor), amalgamated with another legal entity, demerged, or otherwise disposed of.
- If there is any change in the constitution of the business.
- If the taxable person is no longer liable to be registered.
Registration may be cancelled retrospectively if the proper officer deems it appropriate in certain situations, such as:
- If the registered person has violated provisions of the Act or Rules.
- If a person paying tax under the Composition Scheme has not filed returns for three consecutive tax periods.
- If any taxable person has not filed returns for a continuous period of six months.
- If a person who has voluntarily registered has not commenced business within six months from the date of registration.
- If registration has been obtained through fraud, willful misstatement, or suppression of facts.
The cancellation of registration does not affect the taxable person's liability to pay tax and other dues under the Act for any period prior to the date of cancellation, regardless of whether such tax and dues are determined before or after the date of cancellation.
Upon cancellation of registration, the registered taxable person must pay an amount equivalent to the input tax credit for inputs held in stock and inputs contained in semi-finished or finished goods held in stock on the day immediately preceding the date of cancellation, or the output tax payable on such goods, whichever is higher. This payment can be made by debiting the electronic credit or electronic cash ledger.
In the case of capital goods, the taxable person must pay an amount equal to the input tax credit taken on the capital goods, reduced by a prescribed percentage, or the tax on the transaction value of such capital goods, whichever is higher.
Revocation of Cancellation of Registration
- Registered taxable persons whose registration has been cancelled can apply to the proper officer for revocation of the cancellation within thirty days from the date of service of the cancellation order.
- The proper officer must provide a show cause notice and give the person a reasonable opportunity to be heard before rejecting the application for revocation.
