GST Registration Amendment: What to Update and How

Goods and Services Tax (GST) registration amendment is the process of updating business details, such as trade name, business location, authorised signatory or submitting a consent letter for GST, after registration. These changes directly affect invoices, return filings and compliance records.

If the information on the GST portal does not match actual business details, it can lead to validation issues during return filing or while claiming input tax credit (ITC). GST law requires these updates to be recorded through a formal amendment process, with specific requirements depending on the nature of the change.

Who can file a GST amendment application?

The GST amendment is not limited to normal taxpayers. The following registered entities can file amendments:

• Normal taxpayers and new registrants who need to correct or update registration details
• Tax deducted at source (TDS) and tax collected at source (TCS) deductors or collectors registered under GST
• Non-resident taxable persons operating in India
• GST practitioners authorised to act on behalf of taxpayers
• Online information and database access or retrieval (OIDAR) service providers and notified persons with a unique identification number (UIN)

Types of GST Registration Amendments

GST amendments are classified into two groups based on approval requirements.

• Core field amendments

Core fields are important business details that require GST officer approval. These include:

• Trade name of the business
• Principal place of business
• Additional place of business
• Details of partners, directors or authorised signatories

The main rules for core amendments are:

• Must be submitted using Form GST REG-14
• Requires uploading documents and specifying the reason for the change
• Approval is issued in Form GST REG-15
• Processing time is typically within 15 working days

Note: If the officer takes no action within the prescribed time, the amendment is deemed approved and the certificate is updated.

• Non-core field amendments

Non-core fields are minor details and do not require officer approval. These include:

• Email ID and mobile number
• Bank account details
• Minor profile updates

The key rules for non-core amendments are:

• Changes are updated immediately after submission
• No approval is required
• Authentication using a digital signature certificate (DSC) or electronic verification code (EVC) is mandatory

Changes take effect from the date of the event, not the submission date.

Note: If the GST officer does not act on a core amendment within the prescribed time, it is treated as deemed approval.

Trade name change under GST

A trade name is the name under which a business operates and may differ from its legal name. Changing the trade name is a core amendment and results in the issuance of a revised GST registration certificate.

Key rules for trade name change:

• File Form GST REG-14 within 15 days
• Provide supporting documents such as a board resolution or partnership deed
• GSTIN does not change upon approval
• A new registration certificate is issued after approval

Up to nine additional trade names can be added, provided they are declared and supported by valid documentation.

Address update in GST registration

An address change, especially for the principal place of business, is treated as a core amendment. The conditions include:

• File the amendment using Form GST REG-14
• Upload valid address proof (electricity bill, rent agreement or property documents)
• GST officer verification is required
• Approval updates the GST registration certificate

For special economic zone (SEZ) units or developers, government-issued certificates must be submitted. If a rent agreement is not available, an affidavit along with utility bills can be submitted.

Addresses must match the PIN code and system mapping to avoid validation issues.

If the business shifts to another state:

• Cancel the existing GST registration
• Obtain a new registration in the new state
• Amendment is not allowed in this case

Process to make amendments in GST registration details

Follow these steps to file a GST amendment:

1. Log in to the GST portal using valid credentials
2. Navigate to Services > Registration > Amendment
3. Select the field type (core or non-core)
4. Update details carefully to avoid mismatches
5. Upload supporting documents
6. Authenticate using DSC, e-sign or EVC

Enter the reason and date of amendment before submission.

A GST officer may issue a notice within 15 days if documents are incomplete. An ARN is generated upon submission and serves as proof of application. An acknowledgement is typically sent within 15 minutes to the registered contact details.

Compliance rules and restrictions regarding amendments to GST

GST law defines what can and cannot be amended.

Key restrictions include:

• PAN cannot be changed; a new registration is required
• State change is not permitted as GST registration is state-specific

Other compliance conditions include:

• Clearly state the reason for the amendment
• Only one amendment application can be active at a time
• Digital verification is mandatory before submission

Note: If an amendment is under processing (ARN generated), a new application cannot be filed. Amendments are also not allowed if cancellation or withdrawal is pending.

Conclusion

GST registration amendment is a compliance requirement whenever business details change. It must be filed within the prescribed timeline with accurate classification and supporting documents.

Businesses should ensure that updates are complete and consistent with records to avoid rejection or follow-up notices. Using TallyPrime helps maintain updated records, track changes and generate accurate GST compliance reports, reducing the risk of errors and notices.
