How to Update or Change GST Registration Details Online? – Complete Guide

Last Updated on July 3, 2026

GST registration is not a one-time compliance requirement. As a business grows, changes such as a new business address, an additional place of business, an updated bank account, a change in partners or directors or a modification in business activities may require amendments to the GST registration details. Keeping your GST information up to date is essential to ensure compliance with GST laws and to avoid unnecessary notices, penalties, or disruptions to business operations.

The Goods and Services Tax (GST) Portal allows various registered taxpayers to update or amend their registration details online. While some of the changes are approved automatically, others may require verification and approval by the tax authorities.

This detailed guide explains how to update GST registration details online, including eligibility, types of amendments, required documents, the step-by-step process, timelines, compliance requirements and the common mistakes to avoid.

What is a GST Registration Amendment?

A GST registration amendment is the process of updating or modifying the information submitted during GST registration.

Businesses may need to update details such as: –

• Business name
• Trade name
• Principal place of business
• Additional places of the business
• Bank account details
• Authorized signatory
• Email address
• Mobile number
• Nature of the business activities
• Partners or directors

The amendment ensures that the GST records maintained by the tax authorities accurately reflect the current business information.

Why is Updating GST Registration Details Important?

Updating GST registration details is an important compliance requirement for every registered business.

• Ensures Legal Compliance: GST laws require businesses to update the specified changes within the prescribed time limit. Failure to do so may result in compliance issues.
• Prevents Notices and Penalties: Outdated registration details may lead to notices from the GST authorities and create unnecessary legal complications.
• Smooth Business Operations: Accurate GST information helps businesses complete banking formalities, vendor onboarding, licensing procedures and government registrations without delays.
• Accurate Tax Records: Updated registration details ensure GST returns, invoices and tax records contain correct business information.
• Builds Business Credibility: Customers, suppliers and financial institutions are more likely to trust businesses that maintain accurate statutory records.

What is the Time Limit to Update GST Registration Details?

Under Rule 19 of the CGST Rules 2017, any change in GST registration details must be intimated to the GST authorities within 15 days of the occurrence of the change.

Missing this 15-day window doesn’t just create a technical lapse; it can attract penalties under Section 122 of the CGST Act for non-compliance with registration provisions. For something as routine as a change of address or addition of a director, many businesses discover this deadline only after receiving a notice.

Who Can Update GST Registration Details?

The following registered taxpayers can apply for GST registration amendments: –

• Sole Proprietorships
• Partnership Firms
• Limited Liability Partnerships (LLPs)
• Private Limited Companies
• Public Limited Companies
• One Person Companies (OPCs)
• Trusts
• Societies
• Other registered taxable persons

The amendment application is generally submitted by the authorised signatory through the GST Portal.

What Happens If You Don’t Update on Time?

Operating with outdated GST registration details isn’t just an administrative lapse. Under Section 122 of the CGST Act, issuing invoices with incorrect or outdated business details can attract a penalty of ₹10,000 or the tax amount involved, whichever is higher.

Additionally, continued non-compliance after a GST notice can lead to suspension or cancellation of GST registration, which directly disrupts your ability to collect tax, claim ITC, and operate legally.

Multiple GST Registration (Multi-State) Amendment

GST registration is state-specific. If your business has GSTINs in multiple states, any change to the business name, authorised signatory, or constitution must be updated separately for each state registration.

A common mistake: businesses update their home-state GSTIN but forget to amend the other state registrations. This creates mismatches in GSTR filings, e-way bills, and supplier records, and each missed amendment is a separate compliance violation.

Types of GST Registration Amendments

GST registration amendments are broadly divided into two categories.

1. Core Field Amendments

Core fields are important business details that generally require approval from the GST authorities.

Examples include: –

• Legal name of the business
• Principal place of business
• Additional places of business
• Addition or removal of partners or directors
• Change in authorised signatory
• Business constitution

2. Non-Core Field Amendments

Non-core fields generally do not require approval and are updated automatically after submission.

Examples include: –

• Email address
• Mobile number
• Bank account details
• Contact information

Businesses should review the latest GST provisions before applying for any amendment.

When Is Amendment Not Enough?

Not every business change can be handled through an amendment. Certain changes require cancelling the existing GSTIN and obtaining a fresh registration:

• Change from sole proprietorship to a company or LLP (since the legal entity itself changes)
• Transfer of business through sale or merger
• Death of a sole proprietor (successor must register afresh)

Filing an amendment in these situations instead of a fresh registration is a compliance error that can create ITC mismatches and legal complications later. When in doubt, consult a GST professional before choosing between amendment and fresh registration.

PAN-Linked Changes Cannot Be Amended on GST Portal

One Important Restriction — PAN-Based Details Cannot Be Amended

The legal name of the business, as it appears on GST registration, is linked to the PAN. If your PAN-registered legal name changes (for example, after a company name change with the ROC), you must first update the name with the Income Tax Department and the PAN database. The GST portal will only reflect the change after the PAN records are updated.

Trying to amend the legal name directly on the GST portal without first updating PAN will result in an error or rejection.

Documents Required for GST Registration Amendment

The required documents depend on the type of amendment.

Identity Documents

• PAN Card
• Aadhaar Card
• Identity proof of the authorised signatory

Address Proof

For address changes: –

• Electricity bill
• Property tax receipt
• Rent agreement
• No Objection Certificate (NOC)

Business Documents

Depending on the amendment: –

• Certificate of Incorporation
• Partnership Deed
• LLP Agreement
• Board Resolution (where applicable)

Bank Documents

• Cancelled cheque
• Bank statement
• Passbook copy

Supporting Documents

Additional supporting documents may be required depending on the nature of the amendment.

Step-by-Step Procedure to Update or Change GST Registration Details Online

Step 1: Log in to the GST Portal

Visit the GST Portal and log in using your GST username and password.

Step 2: Navigate to Amendment of Registration

Select Services > Registration > Amendment of Registration from the dashboard.

Note: The GST amendment application is formally filed through Form GST REG-14 on the portal. For core field amendments, the GST officer processes this using Form GST REG-15 (approval order). Knowing these form names matters when tracking your application status or responding to professional advisors. The portal and official notices reference these form numbers directly.

Step 3: Choose the Details to be Updated

Select the information you wish to amend, such as:

• Business address
• Trade name
• Authorized signatory
• Bank account
• Business constitution
• Partner or director details

Step 4: Enter the Updated Information

Fill in the revised details carefully and verify all the information before proceeding.

Step 5: Upload Supporting Documents

Upload the relevant supporting documents in the prescribed format for the requested amendment.

Step 6: Verify and Submit the Application

Authenticate the application using:

• Digital Signature Certificate (DSC), where applicable
• Electronic Verification Code (EVC)
• Aadhaar authentication, where permitted

Submit the application after successful verification.

Timeline for GST Registration Amendment

The time required to process a GST registration amendment depends on the type of amendment requested.

Specific Processing Timelines Under GST Law

Amendment Type	Processing Time
Non-core fields (auto-approved)	Immediately upon submission
Core fields — officer approval	Within 15 working days
If clarification is sought by the officer	An additional 7 working days after your response
If no action by the officer within 15 days	Amendment deemed approved automatically

The “deemed approval” provision is important if the GST officer doesn’t act within 15 working days, your core field amendment is automatically approved. Many businesses don’t know this and keep waiting unnecessarily.

Compliance Requirements After Updating GST Registration Details

Updating GST registration is only one aspect of compliance.

1. Update Business Documents

Reflect the amended information in:

• GST invoices
• Letterheads
• Purchase orders
• Business agreements
• Company website

2. Inform Customers and Vendors

Communicate important changes, such as business name or address, to customers, suppliers and financial institutions.

3. Update Other Registrations

Where applicable, update the revised details in: –

• PAN
• TAN
• Import Export Code (IEC)
• Shops and Establishments Registration
• Professional Tax Registration
• Other statutory registrations

4. Continue GST Compliance

Continue filing GST returns, maintaining books of account and complying with GST laws.

Benefits of Updating GST Registration Details

• Ensures Legal Compliance: Maintains compliance with GST regulations.
• Avoids Legal Issues: Reduces the likelihood of notices, penalties and disputes.
• Smooth Business Operations: Supports uninterrupted banking, licensing, vendor onboarding and business transactions.
• Improved Business Credibility: Accurate and proper registration details strengthen confidence among stakeholders.
• Better Communication: Ensures receipt of important notices and communications from the GST authorities.
• Accurate Tax Records: Support proper GST return filing and record keeping.

Practical Example

A Partnership Firm shifts its office to a new commercial location after business expansion. Since the principal place of business changes, the partners log in to the GST Portal and submit an amendment application. They upload the rent agreement, electricity bill and No Objection Certificate (NOC) as supporting documents.

After the process of verification, the GST authorities approve the amendment and the updated address appears in the GST registration records. The firm also updates its invoices, website, bank records and other statutory documents to ensure consistency and compliance.

How Professional Assistance Can Help

Professional GST consultants can assist businesses in identifying the appropriate amendment, preparing supporting documents, filing online applications, responding to departmental notices, and ensuring timely approval. Expert assistance minimises the errors, reduces delays and helps businesses remain fully compliant with GST regulations.

Conclusion

Updating GST registration details is an important compliance requirement for every registered business. Whether the change relates to the business address, trade name, partners, directors, bank account or authorised signatory, a timely amendment helps to maintain accurate and proper government records and ensures uninterrupted business operations.

Understanding the amendment process, submitting the correct documents and complying with post-amendment requirements can help businesses to avoid penalties and administrative challenges. Professional guidance can further simplify the process and ensure complete compliance with GST laws.
