GST Registration Amendment: How to Change Business Details on GST Portal

Need to Update GST Details? Understand the Amendment Process Before Making Changes

After obtaining GST registration, businesses often experience changes in their operations. A company may shift its office location, change contact details, add a new business activity, modify partner/director information, or update authorised signatory details.

Many taxpayers assume that once GST registration is approved, the details cannot be changed. However, GST law allows registered taxpayers to update certain information through the GST Registration Amendment Process.

The amendment facility helps businesses keep their GST records accurate and updated without applying for a fresh GST registration.

Some common situations where businesses need GST amendment include:

• Change in business address.
• Addition or removal of partners/directors.
• Change in mobile number or email ID.
• Change in authorised signatory.
• Addition of additional place of business.
• Change in bank account details.
• Modification of business activity details.

However, businesses should understand that the classification of these changes depends on the specific field being amended and the nature of the taxpayer’s registration details. Every change does not follow the same approval process.

For example, authorised signatory details are treated differently from changes affecting the principal place of business or constitution-related details.

Keeping GST registration details updated is important because incorrect information may create problems during:

• GST Return filing.
• Refund applications.
• Department verification.
• GST notices.
• Business transactions.

This complete guide explains GST registration amendment, types of changes, core and non-core field classification, documents required, step-by-step procedure, approval timeline, examples, and important compliance points.

What Is GST Registration Amendment?

GST Registration Amendment means updating or modifying the details provided in the GST registration application after registration has already been approved.

A registered taxpayer can modify specific information through the GST portal by submitting an amendment application.

The amendment process allows businesses to correct or update details without cancelling the existing GST registration.

For example:

A business registered in Delhi shifts its office to another location within the same state.

Instead of applying for a new GST registration, the taxpayer can submit an amendment application to update the principal place of business.

However, if the business shifts its operations to another State, it should not be treated as a routine amendment of the existing GST registration.

Since GST registration is State-specific, the taxpayer should evaluate registration requirements in the new State instead of simply modifying the existing registration.

Example:

ABC Private Limited is registered under GST in Delhi.

The company permanently shifts its business operations to Maharashtra.

In this situation, the company needs to evaluate GST registration requirements applicable in Maharashtra rather than treating it as only a Delhi GST amendment.

Why Is GST Registration Amendment Required?

GST registration details represent the legal identity of a business on the GST portal.

Any mismatch between actual business details and GST records can create compliance issues.

Businesses should update GST information because:

1. Maintains Accurate Government Records

GST authorities rely on registration details for communication, verification, and compliance monitoring.

If the registered address or authorised person changes but GST records remain outdated, it may create unnecessary confusion.

For example:

A company appoints a new person to manage GST compliance but does not update authorised signatory details.

The previous authorised person may continue appearing in GST records, creating difficulty in handling compliance activities.

2. Avoids GST Notice Issues

Incorrect GST details can result in questions from authorities.

For example:

If a business operates from a new address but GST registration still shows the old location, verification issues may arise.

Similarly, incorrect business activity details may create differences between actual operations and GST records.

3. Helps in Smooth Business Transactions

Customers and vendors often verify GST details before starting business relationships.

Updated GST information improves transparency and credibility.

For example:

A large company onboarding a supplier may verify GST registration details before approving the vendor.

If the business address or legal details do not match, it may delay the onboarding process.

4. Ensures Correct GST Communication

GST notices, alerts, and important communications are sent based on registered details.

Incorrect email or mobile number may result in missed compliance updates.

Therefore, businesses should ensure that communication details available on the GST portal remain updated.

Types of GST Registration Amendments

GST registration amendments are broadly classified into two categories:

1.    Core Field Amendments

2.    Non-Core Field Amendments

Understanding this difference is important because the approval process differs for both.

However, businesses should not rely on a fixed permanent list because GST amendment classification depends on the specific field being changed and the taxpayer’s registration details.

The GST portal categorises different fields based on their importance and verification requirements.

Some amendments require approval from the GST officer, while certain non-core changes are automatically updated after submission.

Core Field Amendments Under GST

Core field amendments generally relate to important registration details that may affect the identity, legal structure, or business location of the taxpayer.

These changes generally require verification and approval from the GST officer.

Examples may include:

• Principal place of business.
• Addition of additional place of business.
• Certain constitution-related changes.
• Legal name changes, subject to applicable conditions.

The exact classification depends on the field being amended and the taxpayer’s registration details.

Non-Core Field Amendments Under GST

Non-core fields generally relate to routine information changes that do not significantly alter the identity or registration status of the taxpayer.

These changes are generally processed automatically after successful submission.

Examples include:

• Authorised signatory details.
• Mobile number.
• Email address.
• Certain bank account details.
• Other permitted non-core information.

As per GST portal guidance, authorised signatory details are treated as non-core field amendments. Therefore, such changes generally do not require approval from the GST officer and are updated through the amendment process after submission.

Difference Between Core and Non-Core Amendments

Common Reasons for GST Registration Amendment

1. Change in Business Address

One of the most common reasons for GST amendment is a change in business location.

This may happen because:

• Business expands.
• Company shifts office.
• Rental agreement expires.
• Business moves to a larger premises.

The taxpayer needs to update:

• Principal place of business.
• Additional place of business.

A change in address within the same State can generally be updated through GST amendment.

However, movement of business operations from one State to another requires separate evaluation because GST registration is linked to the State where the taxpayer is registered.

2. Change in Legal Name of Business

A business name may change due to:

• Rebranding.
• Changes in business constitution.
• Conversion of business structure.
• Other legally recognised reasons.

Example:

A partnership firm changes its name after restructuring the business.

The GST registration details should be updated accordingly.

However, legal name amendment is subject to the corresponding change in PAN or legal constitution, wherever applicable, because GSTIN is PAN-based.

3. Change in Partners, Directors, or Proprietor Details

Businesses may need amendment when there is a change in:

• Partner.
• Director.
• Proprietor.
• Promoter details.

This is common in:

• LLPs.
• Partnership firms.
• Private limited companies.

However, businesses should review the exact GST amendment requirement because classification depends on the legal structure and the specific registration field being modified.

For example:

A partner change in an LLP and a director change in a private limited company may have different compliance implications.

4. Change in Authorised Signatory Details

Businesses often need to update authorised signatory details when:

• The existing authorised person leaves the organisation.
• Management responsibilities change.
• A new person is appointed to handle GST compliance.
• The authorised representative changes.

The authorised signatory is responsible for handling GST-related activities such as:

• Filing GST returns.
• Responding to notices.
• Managing GST portal activities.
• Completing online applications.

Under GST portal classification, authorised signatory details are treated as non-core field amendments.

Therefore, such amendments are generally processed without requiring approval from the GST officer.

Businesses should ensure that:

• The new authorised person's details are correctly entered.
• Required authorisation documents are available.
• The GST portal profile is updated properly.

5. Addition or Modification of Bank Account Details

Businesses may update bank details due to:

• Opening a new business bank account.
• Closing an old account.
• Changing banking arrangements.

Updated bank details help ensure smooth processing of:

• GST refunds.
• Financial transactions.
• Business verification.

The taxpayer should ensure that the bank account belongs to the registered business entity and all information entered matches official records.

6. Change in Business Activity Details

A business may expand or modify its activities after GST registration.

For example:

A trader registered under GST starts manufacturing products.

In such cases, the taxpayer should review whether the existing GST registration details accurately represent the current business activities.

Updating business activity details helps maintain consistency between:

• GST registration.
• GST returns.
• Invoices.
• Actual operations.

Documents Required for GST Registration Amendment

The documents required depend on the type of amendment being requested.

Businesses should keep relevant supporting documents ready before submitting the application.

1. Documents for Business Address Change

For updating principal or additional place of business, documents may include:

• Ownership proof of premises.
• Rent agreement.
• Electricity bill.
• Property tax receipt.
• Consent letter from owner (where applicable).
• NOC from owner (where applicable).

The exact document requirement depends on the nature of the premises.

2. Documents for Legal Name Change

Documents may include:

• Updated incorporation documents.
• Revised partnership deed.
• ROC approval documents (where applicable).
• Other legal documents supporting the change.

Since GSTIN is linked with PAN, businesses should ensure that the legal name change is properly reflected in relevant records wherever required.

3. Documents for Partner/Director Changes

Depending on business structure, documents may include:

• Updated partnership deed.
• LLP agreement.
• Board resolution.
• Director-related documents.
• Authorisation documents.

Businesses should verify the applicable requirement based on whether the entity is a:

• Partnership firm.
• LLP.
• Private limited company.
• Other registered entity.

4. Documents for Authorised Signatory Change

Documents may include:

• Authorisation letter.
• Board resolution.
• Partner approval.
• Identity details of authorised person.

Since authorised signatory is a non-core amendment, businesses should ensure that the updated details are correctly submitted through the GST portal.

Step-by-Step Process for GST Registration Amendment on GST Portal

The GST amendment application is submitted online through the GST portal.

Step 1: Login to GST Portal

The taxpayer needs to login using:

• GST username.
• Password.

After successful login, navigate to:

Services → Registration → Amendment of Registration Core Fields / Non-Core Fields

The taxpayer should select the appropriate amendment option based on the details that need modification.

Step 2: Select the Required Amendment Section

The GST portal provides different sections for updating registration details.

The taxpayer should select the relevant section such as:

• Business details.
• Principal place of business.
• Additional place of business.
• Promoter/partner details.
• Authorised signatory.
• Bank details.

Selecting the correct section helps avoid unnecessary rejection or delays.

Step 3: Modify Required Information

The taxpayer updates the required details carefully.

Before submission, verify:

• Spelling of business name.
• Address details.
• Contact information.
• Partner/director details.
• Supporting documents.

Incorrect information may result in:

• Clarification requests.
• Rejection.
• Additional compliance steps.

Step 4: Upload Supporting Documents

Where required, upload supporting documents.

Documents should:

• Be clear and readable.
• Match the updated information.
• Follow GST portal file requirements.

Poor-quality or unrelated documents may delay approval.

Step 5: Submit Application Through DSC/EVC

After completing the amendment form, the taxpayer submits the application using:

• Digital Signature Certificate (DSC), or
• Electronic Verification Code (EVC), as applicable.

After successful submission, an Application Reference Number (ARN) is generated.

Businesses should save the ARN for tracking purposes.

GST Registration Amendment Approval Process

The approval process depends on the type of amendment submitted.

Non-Core Amendment Approval

Non-core amendments are generally processed automatically after submission.

Examples:

• Authorised signatory details.
• Mobile number.
• Email address.

No separate approval from the GST officer is generally required.

Core Amendment Approval

Core amendments may require review by the GST officer.

The officer may:

• Approve the application.
• Raise clarification.
• Reject the application with reasons.

Businesses should respond to clarification requests within the prescribed timeline.

GST Registration Amendment Timeline

The time required depends on:

• Type of amendment.
• Documents submitted.
• Department verification.

Non-core changes are generally faster because they are automatically processed.

Core amendments may take longer due to officer review.

Reasons Why GST Amendment Application May Be Rejected

Businesses should avoid common mistakes that lead to rejection.

1. Incorrect Information Provided

Mismatch between submitted information and supporting documents can result in rejection.

Example:

The address entered in the application does not match the uploaded electricity bill.

2. Missing Supporting Documents

If required documents are not attached, the officer may reject the application or request clarification.

3. Invalid Documents

Documents that are:

• Expired.
• Unclear.
• Unrelated.

may not be accepted.

4. Wrong Amendment Category Selected

Selecting the incorrect amendment type may create processing issues.

Businesses should carefully identify whether the change relates to:

• Core field.
• Non-core field.

Practical Example: GST Address Amendment

ABC Traders operates from Delhi and shifts its office to another location within Delhi.

The business updates:

• Principal place of business.
• New address proof.
• Supporting documents.

After verification, the GST registration details are updated.

However, if ABC Traders shifts its entire business to another State, it should evaluate fresh GST registration requirements instead of simply modifying the Delhi registration.

Practical Example: Authorised Signatory Update

XYZ Private Limited had its finance manager handling GST compliance.

After the finance manager resigned, the company appointed a new authorised person.

The company updated authorised signatory details on the GST portal.

Since authorised signatory is treated as a non-core field amendment, the update was processed without requiring GST officer approval.
