How to Update GST Registration Details Online?

Keeping your business details up to date under GST is not just a formality, but a legal requirement. Whether you have changed your address, contact info, or business structure, updating your GST registration online is quick and easy through the official GST portal. This ensures smooth compliance, avoids penalties, and keeps your GSTIN active and accurate for seamless operations. In this article, you will learn how to update GST registration details online easily and hassle-free.

When Should You Update the GST Registration?

You should update your GST registration details whenever there is a change in your business information that was originally submitted during GST registration. This includes changes such as your business address, legal name, contact number, email ID, business structure (like sole proprietorship to partnership), addition or removal of partners/directors, principal place of business, or nature of business activities.

As per the GST Act, it is mandatory to update this information on the official GST portal within 15 days of the change. Failing to do so can lead to penalties or disruption in GST services like return filing or claiming Input Tax Credit (ITC). Keeping your GST registration updated ensures smooth communication with tax authorities and avoids legal issues. It also helps maintain your GST compliance rating and builds trust with clients and suppliers.

Who Can Update the GST Registration?

The responsibility to update GST registration details lies with the authorised signatory of the registered taxpayer. This could be the business owner, partner, director, proprietor, trustee, or any authorised person nominated while registering on the GST portal.

As per GST rules under the CGST Act, 2017, only the authorised person who has access to the GST account and a valid Digital Signature Certificate (DSC) or Electronic Verification Code (EVC) can make changes to the registration. This ensures that only verified and responsible individuals manage sensitive tax and business information.

The following registered persons can update their GST registration:

• Proprietors of sole proprietorship firms
• Partners of partnership or LLP firms
• Directors or Board Members of private or public limited companies
• Karta in the case of HUF (Hindu Undivided Family)
• Trustees of a trust
• Society or club managers

The GST portal allows them to log in securely, navigate to the amendment section, and file a change request online. Some changes require approval by a GST officer, while minor updates like mobile number or email ID (linked with Aadhaar) may be auto-approved. Keeping your registration updated ensures smooth operations, prevents legal penalties, and maintains your business credibility.

Types of Amendments in GST Registration

When your business details change, it is important to update your GST registration to stay compliant. The Goods and Services Tax (GST) Act allows registered taxpayers to amend their registration details online through the official GST portal. These amendments are classified into three main categories, based on the nature of the change.

Core Field Amendments

These are major changes that require approval from a GST officer. They include:

• Change in the legal name of the business (excluding change due to PAN update)
• Change in the principal place of business or additional places of business
• Change in partners, directors, Karta, managing committee members, etc.

It must be changed or updated within the 15 days of the change. Approval may take up to 15 working days after document verification.

Non-Core Field Amendments

These are minor changes that do not require approval and are auto-updated in the GST system. Examples include:

• Changing the email ID or mobile number of the authorised signatory (via Aadhaar OTP)
• Updating bank account details
• Modifying authorised signatory (without changing DSC holder)

These can be amended directly by logging in to the GST portal.

Amendments Requiring New Registration

Some changes are so significant that they require a fresh GST registration rather than an update. These include:

• Change in PAN, like from sole proprietorship to a private limited company
• Change in the constitution of the business, like a partnership to a company

In these cases, you must cancel the existing registration and apply for a new one.

How to Update GST Registration Details Online?

The following details include how to update GST registration online:

Step 1: Visit the GST Portal

Go to the official GST portal and Click on "Login" and enter your username, password, and captcha code.

Step 2: Navigate to the Amendment Section

After logging in, go to the “Services” tab on the top menu.

Click on "Registration" > “Amendment of Registration Non-Core Fields” or “Amendment of Registration Core Fields”, depending on what you want to change.

Step 3: Choose the Field to Update

The portal offers different options to update various fields:

• Core Fields (require approval): Business name, principal place of business, additional places, or key persons
• Non-Core Fields (auto-approved): Email ID, phone number, bank details, and minor changes

Choose the section that matches your update (e.g., “Principal Place of Business” for address change).

Step 4: Make the Necessary Changes

• Update the details carefully.
• Ensure that all entered information matches your official business records.

For example:

• If you are changing your business address, enter the new address and upload proof of address (like an electricity bill, rent agreement, or property tax receipt).
• If you are changing partners or directors, provide relevant documents and ID proofs.

Step 5: Upload Supporting Documents

You will be asked to upload supporting documents depending on the type of change. These must be in PDF or JPEG format (max file size: 1MB per document).

Common documents required include:

• PAN card
• Aadhaar card
• Board resolution or authorisation letter
• Address proof (utility bill, lease agreement)
• Proof of identity and address of the new signatory/director/partner

Step 6: Verification and Authentication

Once all details are entered and documents uploaded:

• Click "Submit"

If you are an individual, EVC via Aadhaar OTP is usually accepted. For companies or LLPs, DSC is mandatory.

Step 7: ARN Generation and Tracking

Once submitted, an Acknowledgement Reference Number (ARN) is generated. You can use this to track your application status:

• Go to “Services” > “Track Application Status” > Enter ARN

For core field amendments, a GST officer may take up to 15 working days to approve or reject the application. You may receive a notice if any clarification or document is missing.

Step 8: Approval and Certificate Update

• Once approved, the updated details will be reflected in your GST registration certificate.
• You can download your new certificate from “My Profile” > “View/Download Certificate.”

If the application is rejected, you will be informed of the reason, and you can file a fresh amendment with the correct details.

Timeline and Processing of GST Amendments

As per GST rules, any changes in your business details must be updated on the GST portal within 15 days of the change. Once you submit the amendment application, a unique ARN (Acknowledgement Reference Number) is generated for tracking.

• Non-core field amendments (like contact details or bank info) are usually auto-approved.
• Core field amendments (like business address, legal name, or authorised signatory) are reviewed by a GST officer and processed within 15 working days.

If the officer needs more information, you will receive a notice via email/SMS. You must respond within 7 working days. Once approved, the changes reflect in your updated GST registration certificate, available for download on the portal. Keeping your GST records updated on time helps avoid penalties and ensures smooth compliance.

Benefits of Updating GST Registration Details

The details below include the benefits of updating GST registration details:

• Ensures Legal Compliance

As per Section 25 of the CGST Act, 2017, a taxpayer must update any changes in business details within 15 days of such changes. This includes amendments in name, address, partners, directors, and nature of business. Timely updates protect your business from penalties, notices, or suspension of your GSTIN.

• Keeps the Input Tax Credit (ITC) Flow Smooth

If your GST details (like business name, GSTIN, or address) are outdated or incorrect, your buyers may face difficulty claiming Input Tax Credit. Any mismatch in invoice details could lead to rejection or delay in ITC. Keeping your registration updated helps you and your clients maintain a clean and uninterrupted ITC chain, which is crucial for GST returns.

• Avoids Delays in GST Filings and Refunds

When your business details don’t match your registration data, it can lead to errors while filing GST return (GSTR-1, GSTR-3B, etc.) or applying for refunds. For example, an outdated authorised signatory may not receive OTPs, or a wrong bank account may delay GST refunds. Correct details ensure that returns are filed on time and refunds are credited smoothly.

• Supports Seamless Communication with Tax Authorities

Updating your mobile number, email address, or authorised signatory ensures that you receive important alerts, OTPs, return reminders, and government notices without delay. Missed communication can lead to missed deadlines, show cause notices, or penalties.

• Reflects Real-Time Business Changes

Businesses grow and change with time, new branches are opened, addresses shift, and ownership structures evolve. Updating these details in your GST registration keeps your documents current and aligned with actual operations. Updated records help you stay audit-ready and increase your credibility with clients, suppliers, and the government.

• Required for Expanding Business Operations

When you plan to open a new branch or warehouse, add new products or services, change your business location, and you must first update your GST registration. Timely updates help avoid issues during inspections, e-way bill generation, or while applying for licenses.

• Builds Business Credibility and Trust

A business that maintains accurate and updated GST records is seen as trustworthy and professional. It enhances your image in the eyes of vendors, partners, banks, and government bodies. Updated GST details help in better client onboarding, tenders, and loan approvals.

• Prevents GSTIN Suspension or Cancellation

If you fail to update your GST details, especially major ones like business structure or address, your GST officer may flag the registration. Continued non-compliance can lead to GSTIN suspension or cancellation, severely affecting your operations. A valid, updated GSTIN keeps your business running smoothly and legally.

Common Mistakes to Avoid While Updating

Here are some common mistakes to avoid while updating GST registration details:

Entering Incorrect Legal Name or PAN Details

One of the most frequent errors is mismatching the legal name with the PAN database. The name entered during the amendment must exactly match the one linked to your Permanent Account Number (PAN). Always cross-check your PAN card and ensure the business name is spelt the same.

Missing the 15-Day Deadline

As per GST rules, you must update any changes in your business details within 15 days of the change. Delaying the amendment can result in:

• Rejection of the application
• Inactive GSTIN
• Legal notices or penalties

Keep a reminder system to initiate updates promptly.

Uploading Blurred or Invalid Documents

Many amendment applications are rejected due to unclear, incorrect, or incomplete documents. For example:

• Uploading a rent agreement without signatures
• Using expired utility bills as address proof
• Submitting bank statements without IFSC details

Ensure documents are recent, legible, and properly signed before uploading.

Wrongly Selecting Core or Non-Core Fields

Confusion between core and non-core field amendments often leads to incorrect submissions. For instance:

• Address changes are a core field (requires officer approval)
• Updating phone number is a non-core field (auto-approved)

Choose the correct amendment category while initiating the process on the GST portal.

Not Authorising the Amendment with DSC/EVC

Your amendment must be digitally signed to be valid. Many users submit applications but skip authentication using:

• DSC (Digital Signature Certificate) – for companies and LLPs
• EVC (Electronic Verification Code) – for individuals and sole proprietors

Incomplete authentication leads to rejection or non-submission.

Wrong Bank Details or Missing Cancelled Cheque

Updating bank account details? Avoid these common errors:

• Entering incorrect IFSC codes
• Uploading blank cheques without the business name
• Forgetting to add all account holders (for joint accounts)

Submit a cancelled cheque with printed business name or a valid bank certificate.

Not Updating Authorised Signatory

If there is a change in business ownership, directors, or partners, the authorised signatory must be updated. Failing to do so means:

• You won’t receive OTPs or alerts
• You cannot file returns or reply to notices

Update the signatory details along with Aadhaar-linked mobile/email.

Skipping Application Tracking or Response to Notices

After submitting an amendment, many businesses forget to:

• Track the Acknowledgement Reference Number (ARN)
• Respond to GST officer notices within 7 working days

Monitor your registered email/SMS and portal inbox for updates.

Updating your GST registration is not just a rule, but a smart move to keep your business running legally and smoothly.
