GST Registration Change & Amendment Services — Update Your GSTIN Details
Address, legal name, partners and directors, bank account, business activity and succession transfers — filed on Form GST REG-14 inside the statutory window
What GST Registration Details Can Be Amended?
Every GST-registered business in India is legally required to keep its GST registration details current and accurate. Business circumstances change — you may move to a new office, add a new partner or director, change your bank account, expand to a new state, or alter your core business activities. When any of these changes occur, a GST amendment must be filed promptly on the GST portal to update your GSTIN records.
At N D Savla & Associates, our chartered accountants in Mumbai provide prompt, accurate GST registration amendment services for businesses of all sizes. We handle everything from simple address changes to complex amendments involving change in constitution of business, transfer of GST registration upon death of a proprietor, and addition of new places of business in multiple states.
Failure to update GST registration details is an offence under the CGST Act. Our team ensures that every amendment is filed correctly and within the prescribed time limit to protect you from penalties and business disruptions.
| Field Type | What It Covers | Approval Route |
|---|---|---|
| Core fields | Legal name of the business (where PAN remains the same), principal place of business address, addition or deletion of partners, directors and promoters, change in constitution of business (for example, proprietorship converting to LLP) | Requires GST officer approval with supporting documents — approved within 15 working days |
| Non-core fields | Bank account details, email address, mobile number of the authorised signatory, addition of authorised signatories, changes to existing places of business within the same state | Auto-approved on the GST portal without officer intervention |
| Requires fresh registration | Expansion to a new state (each state needs its own GSTIN), change of PAN caused by a change in business entity, transfer of business as a going concern to a new entity | Not an amendment — a new GSTIN must be obtained |
When Must You File a GST Amendment?
Change of Business Address
Whether you are relocating within the same city or shifting to a new state, your GST registration must reflect your current principal place of business. For within-state shifts an amendment is filed; for inter-state shifts, a new GST registration for the new state is required alongside deregistration or suspension in the old state.
Addition of New Partners or Directors
When a new partner joins an LLP, or a new director is appointed in a private limited company, the registration must be updated to reflect the new stakeholder's details. This matters particularly because the GST portal requires Aadhaar authentication of all partners and directors on file.
Change of Bank Account
If your business changes its primary bank account, the registration must be updated with the new details. The portal requires a cancelled cheque or bank statement as documentary proof. Failure to update bank details can delay GST refund processing.
Business Name Change
If your business legally changes its name — following a change in the Memorandum of Association, Partnership Deed, or LLP Agreement — the registration must be amended to reflect the new legal name, supported by the amended MOA, board resolution, or updated partnership deed.
Death of Proprietor / Business Succession
When a sole proprietor passes away, the legal heir must apply to transfer the GST registration by filing an amendment with succession documents. Our Estate Planning service works alongside this amendment process so the succession is managed holistically.
Composition to Regular Transition
Businesses leaving the GST Composition Scheme for Goods for the regular regime must file an amendment to update their GST registration category from composition to regular.
How the GST Amendment Framework Developed
Under the pre-GST regime, amendment of indirect tax registrations was a fragmented process. A business changing its registered address had to coordinate amendments across multiple tax departments simultaneously, each with its own form, timeline, and documentation requirement.
| Period | Position | Effect on Business |
|---|---|---|
| Pre-GST — Service Tax | Amendments filed with the Central Excise officer | Separate form, timeline and documentation from every other registration |
| Pre-GST — State VAT | Amendments filed with each state commercial tax department | Multi-state businesses ran parallel amendment processes in every state |
| 2017 | Unified amendment through the common GST portal | Form GST REG-14 for amendment of registration; GST REG-13 for an additional GSTIN in a new state |
| 2017 onward | Core versus non-core field split introduced | Balances speed (auto-approval for non-core) with oversight (officer approval for material changes) |
| 2020 | Aadhaar-based authentication for authorised signatories | Created initial friction but strengthened the integrity of the registration database |
Initial implementation saw significant teething problems: the portal frequently failed during amendment filings, the definition of core versus non-core fields was unclear, and many amendments were rejected for technical rather than substantive reasons. Over successive GST Council decisions and portal upgrades, the amendment process has become considerably more reliable.
Our GST Amendment Process, Step by Step
Change Identification and Documentation
We identify the exact nature of the change and the GST portal fields that need updating, then prepare the required supporting documents — updated lease agreement, incorporation certificate with name change, board resolution, bank statement, and so on.
Form GST REG-14 Preparation
We prepare Form GST REG-14 on the GST portal, entering the amended details in the correct fields and uploading supporting documents. Our team double-checks every field against your GST certificate and master data to prevent errors.
Core / Non-Core Classification
We classify the amendment. Non-core amendments are submitted and auto-approved, with the amended GSTIN certificate available for download within hours. Core amendments move to the GST officer's queue for review and approval within 15 working days.
Officer Response Handling
If the officer raises a query through Form GST REG-03 requesting additional information or documents, we respond through Form GST REG-04 promptly and comprehensively to secure approval without further delay.
Amended GST Certificate Download
Once approved, the amended GST Registration Certificate (Form GST REG-06) is available on the portal. We download and deliver it, confirming that all amended details are correctly reflected.
Downstream Updates
After the amendment, we advise on downstream updates — revising invoice templates with the new GST details, informing key vendors and customers, updating e-invoicing configurations, and amending the address in your e-way bill profile.
GST Amendment for NRIs and Foreign Entities
NRIs and foreign entities registered under GST Registration for Foreigners face additional complexity when amending registrations. Changes to the authorised representative, updates to the Indian bank account, or changes in the nature of supply — for example, switching from NRTP to regular registration — require careful handling to maintain compliance continuity.
Amendment, Revocation or Final Return — Which Applies?
GST Amendment updates the details of an active GSTIN. Two adjacent processes are frequently confused with it, and choosing the wrong one costs weeks.
| Your Situation | Correct Process | Form |
|---|---|---|
| GSTIN is active; registration details have changed | GST Amendment | Form GST REG-14 |
| GSTIN was cancelled by the officer and you want it back | Revocation of GST Cancellation | Form GST REG-21 |
| Business permanently closed | GSTR-10 Final Return — the last compliance step before deregistration is complete | Form GSTR-10 |
| Moving from the composition scheme to the regular regime | Amendment of registration category, alongside opt-out and stock declaration | REG-14 with CMP-04 and ITC-01 |

Why Choose N D Savla & Associates for GST Amendment in Mumbai?
Same-Day Filing for Non-Core Changes
Non-core amendments — bank account, email, mobile, authorised signatory — are filed on the same day you provide the updated information and documents. You receive your amended GSTIN certificate within 24 to 48 hours.
Core Amendment Tracking
For core amendments requiring officer approval, we track the portal status daily and follow up proactively if the timeline exceeds 10 working days — before the mandatory 15-day period expires.
Error-Free Documentation
Our CA team verifies all amendment documents against your existing GST certificate before filing. This eliminates the most common reason for rejection — a discrepancy between submitted documents and current portal records.
Multi-State Amendment Coordination
For businesses requiring coordinated amendments across states — a head-office address change that affects GST registration in five states, for instance — our team manages all state GSTINs simultaneously.
Integrated Compliance View
We maintain a compliance calendar for all your GST registrations and proactively remind you when amendments are required — when a director's term expires, a lease is renewed at a new address, or a new bank account is opened.
Succession-Aware Handling
Transfers on the death of a proprietor are handled jointly with our estate practice, so the GST amendment, the succession documents, and the heir's registration position all move together rather than in sequence.
Frequently Asked Questions — GST Registration Amendment
What is the deadline to file a GST amendment after a business change?
The GST amendment must be filed within 15 days of the change in facts under Section 28 of the CGST Act. Failure to file within 15 days does not automatically void the amendment, but it can attract scrutiny and penalties during audit. N D Savla & Associates advises filing amendments within 7 days of the change to build in a buffer.
Does a GST amendment change the GSTIN number?
No. An amendment updates the details within an existing GSTIN — the 15-digit GST number itself does not change. A new GSTIN is issued only when a business registers in a new state, when the business entity changes (for example, proprietorship to company), or when a fresh registration is obtained after cancellation.
Can I add a new business activity (HSN/SAC code) through a GST amendment?
Yes. Adding a new business activity or changing the primary nature of business is done through the GST amendment process. The new HSN/SAC codes are added in the business activity section of Form GST REG-14.
What if I disagree with an officer's rejection of my GST amendment?
If the GST officer rejects your amendment application through Form GST REG-05, you can file a fresh amendment application after addressing the rejection reason. For improper rejections, an appeal can be filed before the appropriate authority under Section 107 of the CGST Act. Our team assists with both resubmission and appeals.
Is it mandatory to update bank account details within a specific time after the change?
While the law requires amendment within 15 days of any change, the GST portal specifically prompts for bank account validation when you log in after changing accounts. Non-updated bank accounts can delay GST refunds, including ITC refunds, as refunds are credited to the bank account on record. We recommend filing the bank account amendment on the same day the new account is operational.
