GST Registration Amendment in India – Complete 2026 Guide

GST Registration Amendment in India becomes necessary when information furnished at the time of GST registration changes after the GSTIN has been granted. Businesses may need to update their legal name, principal place of business, additional places of business, partners, directors, authorised signatories, mobile number, e-mail address, bank details or other registration particulars.

GST registration particulars should remain consistent with the actual business structure and supporting records. Rule 19 of the CGST Rules provides the statutory framework for amendment of registration and FORM GST REG-14 is the prescribed application for amendment in registration particulars.

The procedure differs depending upon whether the change relates to a core field requiring approval by the proper officer or a non-core field which is generally updated electronically without officer approval.

Businesses requiring professional assistance can refer to our GST Registration Services in India. If you are applying for GST for the first time, see our GST Registration Procedure in India.

Understanding GST Registration Amendment

What is GST registration amendment?

GST registration amendment is the process through which an existing registered taxpayer updates particulars previously furnished to the GST authorities.

The amendment ensures that the information appearing against the GSTIN reflects the taxpayer’s current legal name, constitution, business locations, stakeholders, authorised persons and other relevant particulars.

Rule 19 of the CGST Rules

Rule 19 of the CGST Rules governs amendment of registration. Where particulars furnished in the original registration application or subsequently amended particulars change, the registered person is required to submit the applicable amendment electronically through the common portal.

FORM GST REG-14 is prescribed for amendment of registration particulars. Where approval of a core amendment is granted, the proper officer issues the amendment order in FORM GST REG-15.

Why GST registration details should remain updated

Incorrect GST registration particulars may create inconsistencies between GST records, invoices, MCA records, bank accounts, premises documents and other statutory registrations.

Updating the GST registration promptly is particularly important after a change of office, corporate name, directors, partners or authorised signatory.

When Is GST Registration Amendment Required?

Change after obtaining GST registration

An amendment may be required whenever information originally provided in the GST registration application subsequently changes.

Common events include relocation of the office, opening or closing of an additional place of business, change in the company name, appointment or resignation of directors or partners, change of authorised signatory and modification of contact information.

Mismatch with other statutory registrations

A GST amendment may also become necessary where a corporate or regulatory change has already been completed before another authority.

For example, where the registered office of a company has changed in MCA records, the principal place of business appearing in GST should be reviewed separately and amended where required.

Businesses coordinating multiple registrations may also refer to our Business Licences & Statutory Registrations in India.

Amendment when registered particulars actually change

GST registration should represent the actual particulars of the taxpayer. Businesses should therefore review whether a reportable change falls within the GST amendment framework rather than leaving outdated information on the registration certificate.

Maintaining consistent statutory records can also reduce difficulties during GST audits, refunds, assessments and physical verification.

Core Fields vs Non-Core Fields in GST Registration

What are core fields?

Core fields are important registration particulars for which amendment generally requires examination and approval by the proper officer.

Rule 19 specifically covers changes such as legal name of the business, principal or additional place-of-business addresses and addition, deletion or retirement of specified persons responsible for the business, where the change does not itself require cancellation and fresh registration.

What are non-core fields?

Non-core fields are registration particulars that can generally be updated through the GST Portal without approval from the jurisdictional tax officer.

The GST Portal provides a separate facility under Services > Registration > Amendment of Registration Non-Core Fields.

Difference in approval process

Core-field amendments are subject to verification by the proper officer. Supporting documents should therefore clearly establish the change being requested.

Non-core amendments are generally auto-approved after successful submission and are updated electronically in the GST database.

Separate portal options are available

The GST Portal provides separate options for:

• Amendment of Registration Core Fields; and
• Amendment of Registration Non-Core Fields.

The taxpayer should select the correct route based on the particular information being changed.

Core Field Amendments under GST

Change in legal name of business

A change in the legal name of the business can generally be handled through a core-field amendment where the PAN of the registered person remains unchanged.

For a company, the revised legal name should normally correspond with the name approved by the Ministry of Corporate Affairs and reflected in the applicable corporate records.

Change in principal place of business

A change in the address of the principal place of business is a core-field amendment.

The taxpayer should update the address and provide appropriate documents establishing ownership, tenancy, lease, consent or other lawful occupation of the new premises.

Change in additional place of business

Addition, deletion or modification of an additional place of business may also require a core amendment where it affects the registered business locations.

Examples include opening or closing a branch, warehouse, godown, office, factory or other business premises within the State or Union Territory covered by the GST registration.

Addition, deletion or retirement of specified stakeholders

Rule 19 covers addition, deletion or retirement of partners, directors, Karta, members of the Managing Committee, Board of Trustees, Chief Executive Officer or equivalent persons responsible for the day-to-day affairs of the business.

The GST amendment should be supported with documents corresponding to the underlying corporate, partnership or organisational change.

Non-Core Field Amendments under GST

Trade name and other editable business particulars

Certain business particulars available as non-core fields may be modified directly through the non-core amendment facility on the GST Portal.

The precise fields available for editing should be checked on the live portal because the editable information may depend upon the taxpayer type and registration profile.

Modification of authorised signatory details

Details relating to an existing authorised signatory can generally be modified through the non-core amendment facility where the change does not fall within a core-field category.

The taxpayer should ensure that the person shown as the primary authorised signatory has appropriate authority to undertake GST compliance.

Mobile number and e-mail address

The mobile number and e-mail address of the authorised signatory can be changed through the applicable non-core amendment process.

The GST Portal requires online verification of the revised mobile number and e-mail address through OTP authentication.

Bank and State-specific details

Bank-account particulars and certain State-specific information can also be maintained through the applicable non-core amendment functionality.

Taxpayers should ensure that their updated bank information corresponds with the registered person and applicable PAN requirements.

Step-by-Step GST Registration Amendment through FORM GST REG-14

Step 1 – Login and select the amendment facility

Visit the official GST Portal and login using the registered taxpayer credentials.

Navigate to Services > Registration and select the applicable Core Fields or Non-Core Fields amendment option depending upon the information to be changed.

Step 2 – Enter amended details, date and reason

Open the relevant tab and enter the revised information carefully.

The taxpayer should provide the date of amendment and a concise but accurate reason for the change. The effective date should correspond with the underlying event and supporting documentation, subject to Rule 19.

Step 3 – Upload supporting documents

Upload the documents relevant to the amendment. For example, a change of business premises should be supported by proper address documents, while a company-name change should be supported by the applicable corporate document.

For a detailed premises and entity-document guide, refer to our Documents Required for GST Registration in India.

Step 4 – Verify and submit the application

Complete the verification section, select the authorised signatory and submit the amendment through DSC or EVC, as applicable.

After successful filing, an acknowledgement and ARN are generated or communicated through the GST system, enabling the taxpayer to track the amendment application.

Change of Address in GST Registration

Moving to an owned business premises

Where the business shifts to an owned property, the GST amendment should contain the complete new address and appropriate evidence establishing ownership.

Documents may include an applicable property tax receipt, municipal record, electricity bill, water bill or another acceptable ownership document depending upon the facts.

Moving to rented or leased premises

Where the new principal place of business is rented or leased, the taxpayer should keep the appropriate rent or lease agreement and supporting ownership evidence ready.

The name, premises address and occupancy arrangement appearing in the documents should correspond with the amendment application.

Consent or shared premises

Where a taxpayer operates from premises made available by a relative, group entity or another owner with consent, appropriate consent and ownership documentation should be maintained.

The principles applicable to GST address documents are explained in our GST Registration Documents Checklist.

Change from one State to another

A GSTIN is State or Union Territory specific. A business cannot ordinarily convert a GST registration of one State into the registration of another State merely through an address amendment.

Where business operations move to another State, the taxpayer should separately examine fresh GST registration requirements in the new State and cancellation or continuation of the existing registration, as applicable.

Amendment for Directors, Partners and Authorised Signatories

Addition or deletion of director or partner

Where a director or partner responsible for the business is appointed, resigns, retires or otherwise changes, the GST registration should be reviewed and amended through the applicable core-field process.

The amendment should be supported by appropriate company, LLP, partnership or other organisational documents.

Modification of existing promoter or stakeholder details

A distinction should be made between addition or deletion of a stakeholder and modification of information relating to an existing stakeholder.

The GST Portal classifies various editable particulars between core and non-core facilities. Taxpayers should use the portal option applicable to the particular field being modified.

Change of primary authorised signatory

Where the existing primary authorised signatory leaves the organisation or responsibility for GST compliance is transferred, the taxpayer should update the authorised-signatory details promptly.

If necessary, a new authorised signatory should first be added and made primary before the old authorised signatory is removed.

Keep MCA, LLP and GST records consistent

Companies and LLPs should ensure that changes in directors, designated partners, registered office or legal name completed with the Ministry of Corporate Affairs are also reviewed for consequential GST amendments.

For corporate compliance assistance, see our Company Registration Services in India.

Change in Legal Name, PAN or Constitution of Business

Legal name changes where PAN remains unchanged

Where only the legal name of the business changes and the PAN remains the same, the change can generally be handled through amendment of GST registration.

Rule 19 also provides that a qualifying change in legal name in one State or Union Territory applies to registrations of the person obtained on the same PAN, subject to the GST framework.

Change in PAN requires fresh GST registration

If a change in the constitution of the business results in a change of PAN, amendment of the existing GST registration is not sufficient.

Rule 19 specifically requires the person to apply for a fresh registration in FORM GST REG-01 where the change in constitution results in a change of PAN.

For the fresh-registration process, see our GST Registration Procedure in India.

Conversion, merger or restructuring should be examined carefully

Conversion of a proprietorship into a company, restructuring of a partnership, merger, demerger or another change in legal constitution may affect PAN and GST registration status.

Businesses should determine whether the transaction requires an amendment, fresh GST registration, cancellation of an existing GSTIN, transfer of unutilised input tax credit or other consequential GST compliance.

Updating Bank, Mobile and Other Business Details

Bank account amendment

Bank-account information can be added or updated through the applicable non-core amendment facility on the GST Portal.

The portal may undertake validation of bank and PAN information. Updated bank details are also important for GST refund processing and other portal functions.

Change of mobile number or e-mail

Where the contact information of the primary authorised signatory changes, the taxpayer should update the mobile number and e-mail through the non-core amendment facility.

The new mobile number and e-mail are subject to OTP verification through the GST Portal.

Changes in goods, services or business information

Where business activities evolve after registration, the taxpayer should review whether the corresponding registration particulars require amendment.

This may become relevant when a business introduces new goods or services, changes business activities or needs to update other editable registration information available on the portal.

Documents Required for GST Registration Amendment

Documents for company, LLP or partnership changes

Depending upon the amendment, supporting documents may include a revised Certificate of Incorporation, MCA approval, Board Resolution, LLP records, Partnership Deed, supplementary deed, appointment or resignation documents or other evidence establishing the change.

Only documents relevant to the particular amendment should normally be uploaded.

Documents for change of business address

Address amendments may require an ownership document, rent or lease agreement, consent letter, utility bill or other suitable evidence depending upon the nature of possession of the new premises.

The complete address appearing in the document should correspond with the information entered in the GST amendment application.

Authorisation and supporting explanation

Where the amendment involves a new authorised person or changes requiring corporate approval, an appropriate authorisation letter or Board Resolution may be required.

The reason for amendment entered on the GST Portal should also clearly explain the event giving rise to the change.

GST Amendment Time Limit and Effective Date

Application should generally be filed within 15 days

Rule 19 requires a registered person to submit the amendment application within 15 days of the change in the registration particulars.

Businesses should therefore incorporate GST amendment into their compliance checklist whenever a relevant corporate, address or management change takes place.

Core amendments are generally processed within 15 working days

For amendments requiring officer approval under Rule 19, the proper officer is required to examine the application and, where satisfied, approve the amendment within the prescribed period of 15 working days.

The approval order is issued electronically in FORM GST REG-15.

Retrospective effective date requires attention

Rule 19 contains restrictions on giving an amendment effect from a date earlier than submission of FORM GST REG-14. Such retrospective effect may require an order of the Commissioner, with reasons recorded in writing and subject to applicable conditions.

This is another reason why businesses should file registration amendments promptly rather than allowing changes to remain unreported for extended periods.

REG-03 Clarification, REG-04 Reply and Rejection

FORM GST REG-03 notice

Where the proper officer considers that a core amendment is not warranted or that the documents furnished are incomplete or incorrect, a notice may be issued electronically in FORM GST REG-03.

The notice should be reviewed against the actual amendment application and supporting documents before a reply is filed.

Reply through FORM GST REG-04

The registered person is required to furnish a reply in FORM GST REG-04 within the prescribed period, which under Rule 19 is generally seven working days from service of the notice.

The response should address each query directly and include corrected or additional documents where genuinely required.

Rejection through FORM GST REG-05

If the reply is not satisfactory or no reply is furnished within the prescribed time, the proper officer may reject the amendment application and pass an order in FORM GST REG-05.

Before refiling or taking further action, the taxpayer should understand the exact reason for rejection and correct the underlying issue.

Amendment where the officer takes no action

Rule 19 also contains a deemed-amendment mechanism. If the proper officer does not take prescribed action within fifteen working days of submission of the application, or within seven working days of receiving a reply to REG-03, as applicable, the certificate of registration stands amended to the extent applied for.

The amended registration certificate is then made available electronically on the common portal.

Frequently Asked Questions on GST Registration Amendment

Does GSTIN change when the business address changes?

Ordinarily, an address change within the same State or Union Territory does not by itself change the GSTIN. The registered person should file the applicable core amendment and update the principal or additional place of business.

A move to another State requires separate consideration because GST registration is State-specific.

Can I change the State in an existing GST registration?

A GSTIN is linked to the State or Union Territory of registration. A business generally cannot simply replace one State with another in the same GSTIN through an address amendment.

If operations move to a different State, fresh registration in that State and treatment of the old GST registration should be examined separately.

Can a company change its name without obtaining a new GSTIN?

Where the company’s legal name changes but its PAN remains unchanged, the GST registration can generally be amended through the core-field amendment process.

If the underlying restructuring changes the PAN, fresh GST registration is required instead of merely amending the existing GSTIN.

Can a non-core amendment be filed while another amendment is pending?

The GST Portal permits different workflows for core and non-core amendments, but system restrictions or warnings may arise where another amendment application is already pending.

The live portal status should therefore be checked before starting another amendment. The official GST Portal Non-Core Amendment Manual provides guidance on the portal process.
