GST Amendment Services — Correct and Update Your GST Registration Details
Section 28 compliance handled end to end — Form GST REG-14 filing, Aadhaar authentication, officer query response and downstream e-invoicing updates
What Is GST Amendment and When Is It Required?
GST Amendment is the formal legal process by which a registered taxpayer updates their Goods and Services Tax registration details on the official GST portal. Under Section 28 of the CGST Act, 2017, every registered person is obligated to apply for amendment of their GST registration within 15 days of any change in the particulars furnished at the time of original registration. Failing to do so exposes the business to compliance risk, audit findings, and penalties.
At N D Savla & Associates, our chartered accountants in Mumbai provide comprehensive GST amendment services — from identifying what needs to be amended, preparing all supporting documentation, filing Form GST REG-14, managing officer queries, and delivering the amended GST registration certificate. We serve businesses across Mumbai, Thane, Navi Mumbai, and across Maharashtra.
GST Amendment is distinct from GST Cancellation or Revocation — it keeps your GSTIN active while updating specific registration details. Whether you have changed your business address, onboarded a new director, opened a new bank account, or altered your business activity, a timely and accurate GST amendment keeps your compliance record clean.
What the Amendment Actually Modifies
The amendment modifies information recorded in your GST registration on the GSTIN database maintained by the Goods and Services Tax Network (GSTN). It is filed through Form GST REG-14 for changes to an existing registration, or through the relevant supplementary forms for specific categories — for example, NRTP amendments through modifications to Form GST REG-09.
| Particular Changed | Documentary Proof Typically Required |
|---|---|
| Legal name of the business | Amended MOA, board resolution, or updated partnership deed |
| Principal place of business address | New lease agreement or ownership document, a recent utility bill, and the owner's consent letter where premises are third-party owned |
| Partners, directors, Karta or promoters | DIN, PAN and Aadhaar of each new stakeholder; amended Partnership Deed or LLP Agreement |
| Bank account details used for GST | Cancelled cheque or bank statement in the name of the business |
| Mobile number or email of the authorised signatory | OTP verification on the GST portal |
| Nature of business activities or HSN/SAC codes | Updated activity declaration within Form GST REG-14 |
| Additional places of business within the state | Address proof for the additional premises |
Who Needs to File a GST Amendment?
Companies with Board-Level Changes
Any change in directors of a GST-registered private limited company — appointment of new directors, resignation of existing directors, or change of managing director — requires an amendment including the DIN, PAN and Aadhaar details of each new director.
LLPs and Partnerships with Partner Changes
Addition or retirement of partners in an LLP or traditional partnership firm requires an amendment. The new or outgoing partner's identity documents and the amended Partnership Deed or LLP Agreement must be submitted alongside.
Businesses Relocating Within the Same State
Any change in the principal place of business address within the same state requires an amendment, supported by the new lease agreement, rent receipt or ownership documents alongside the latest utility bill at the new address.
Businesses Expanding to New States
This is not an amendment but a new registration requirement. Expansion to a new state requires applying for a fresh GSTIN for that state through a new GST Registration application.
Businesses Changing Bank Accounts
When a business changes the primary bank account used for GST transactions, an amendment updating the bank details is required. The new account must be validated on the portal for GST refund purposes.
Composition to Regular GST Transition
When a GST Composition Scheme registrant transitions to the regular regime — voluntarily or on threshold breach — an amendment to the registration category is required alongside Form CMP-04 opt-out and Form ITC-01 stock declaration.
GST Amendment in the Indian Indirect Tax Framework
The amendment of indirect tax registrations in India has always been a necessary but administratively burdensome process. Under the pre-GST Service Tax regime, amendments to ST-1 registrations required physical visits to the Central Excise commissioner's office, submission of paper forms, and often multiple follow-ups to secure the amended certificate. State VAT registration amendments were even more fragmented — each state commercial tax department had its own amendment forms and procedures.
| Year | Development | What Changed for Taxpayers |
|---|---|---|
| 2017 | GST launched; GSTN created as the technology backbone | Registration amendments become an online, single-window process |
| 2017 | Core and non-core field distinction introduced — unique to GST | High-frequency, low-risk changes processed instantly; material changes routed through officer review |
| 2018 | New places of business added through the online amendment flow | Replaced paper applications for additional premises |
| 2020 | Aadhaar-based authentication for new partners and directors | Added a verification step for every new stakeholder on the registration |
| Phased | Automated cross-verification against Income Tax, MCA and UIDAI databases | Fewer document-based rejections; faster officer decisions |
Looking forward, the integration of GST registration data with the MCA21 V3 portal — which allows companies to update their registered address once and have it propagated across GST, Income Tax, and MCA databases — represents the next evolution in amendment efficiency.
GST Amendment Process: Step-by-Step Guide
Change Documentation
We collect all documents evidencing the change: updated partnership deed, board resolution, new lease agreement, updated MOA, bank statements, or utility bills. Document quality is checked against portal requirements before filing.
Core vs Non-Core Classification
We classify the change. Non-core changes — bank account, contact details — are filed for immediate auto-approval. Core changes — legal name, address, partners and directors — go through officer review within 15 working days.
Form GST REG-14 Filing
We access the GST portal using the registered taxpayer's credentials, navigate to the Amendment of Registration section, and make the required changes with document uploads. Every entry is double-checked against the current GST certificate before submission.
Aadhaar Authentication for New Stakeholders
New partners or directors being added to the registration must complete Aadhaar-based authentication. We coordinate this with the new stakeholder, ensuring authentication is completed within the portal's session window.
Officer Clarification Response
For core amendments, the officer may issue Form GST REG-03 seeking clarification or additional documents within 15 working days. We file the response through Form GST REG-04 within 7 working days of receiving the notice.
Amended Certificate Download
Once approved, we download the updated Form GST REG-06 certificate and deliver it with a comparison table showing old versus new details for your records and compliance files.
Downstream Compliance Updates
After amendment, we update your e-invoicing system with the new details, revise invoice templates, inform key vendors and customers, and update e-way bill configurations if the place of business address changed.
GST Amendment for Specific Industries in Mumbai
Real Estate and Builders
Real estate developers in Mumbai frequently require amendments when new projects are launched at different addresses, new project-specific bank accounts are opened, or new directors are inducted into the project SPV. Our team handles builder GST amendments with awareness of Mumbai's real estate regulatory environment.
Manufacturing and Trading
Manufacturers in the Mumbai Metropolitan Region who relocate factories from Andheri to Bhiwandi or Vasai require careful coordination of GST address amendments with factory licence and pollution control certificate updates.
Professional Firms
CA firms, law firms, and management consulting practices that onboard new partners must file GST amendments alongside their partnership deed amendments. Freelancers transitioning to partnerships should also consult our GST Registration for Freelancers page for the restructuring implications.
NRI-Owned Businesses
NRIs managing Indian businesses often require amendments when they change their Indian correspondence address, appoint new local directors, or restructure ownership. Our integrated FEMA and GST advisory ensures amendments align with FEMA-mandated disclosures. See our Estate Planning page for succession-related amendment scenarios.

For businesses with multiple GSTINs across states, we manage coordinated amendment filings ensuring consistency across all state registrations — critical where billing systems are centralised.

Frequently Asked Questions — GST Amendment
What is the difference between GST Amendment and GST Cancellation?
GST Amendment updates specific details of an active GSTIN without affecting its validity. GST Cancellation terminates the GSTIN entirely. If your GST has been cancelled and you want to restart, you need Revocation of GST Cancellation rather than an amendment.
Can a GST amendment be filed after the 15-day limit has passed?
Yes. You can file a GST amendment even after 15 days — there is no cut-off after which amendment becomes impossible. However, the amendment will be effective from the date of filing rather than the date of the change, and the period of discrepancy may be flagged during audit. We always recommend filing within 7 days to prevent compliance gaps.
How many times can GST registration be amended?
There is no statutory limit on the number of times a GST registration can be amended. Businesses can file amendments as frequently as their circumstances require, subject to the 15-day timeline after each change.
Does a GST amendment require fresh Aadhaar authentication?
Aadhaar authentication is required specifically when new partners, directors, or authorised signatories are added to the GST registration. For other core changes such as address or business name, Aadhaar authentication of the existing authorised signatory may be required to submit the amendment. Non-core changes do not require fresh Aadhaar authentication.
What documents are needed to amend the principal place of business address?
Required documents include the new lease agreement or ownership document, a recent utility bill (electricity or water, not older than 2 months) at the new address, and the owner's consent letter if the premises are owned by a third party. For registered offices of companies, the board resolution authorising the address change is also required.
