How to Amend GST Registration Details

Core and non-core fields in GST registration, which changes need officer approval, and the step-by-step amendment process on the portal.

Written and reviewed by the GSTIN API team Last reviewed

A GST registration is a record, and records go stale. You move office, add a warehouse, bring in a new partner, switch banks, start selling a new product line. Each of those changes something you declared when you registered, and the law expects you to update it. The mechanism is a single form, GST REG-14, filed under Rule 19 of the CGST Rules. What differs is how the portal treats the change: some fields update the moment you submit, others wait for an officer, and a few cannot be amended at all. This post sorts them.

What Rule 19 and Form REG-14 cover

Rule 19(1) of the CGST Rules applies whenever there is a change in any particular you furnished in your registration application. The registered person files Form GST REG-14 on the common portal, with supporting documents, within 15 days of the change.

The rule then splits the changes into two groups, and that split drives everything else in this post.

  • Core fields, listed in Rule 19(1)(a): the legal name of the business where the PAN is unchanged; the address of the principal place of business or any additional place of business, other than a change of state; and the addition, deletion or retirement of partners, directors, karta, managing committee members, trustees, chief executive officer or equivalent persons responsible for day-to-day affairs. These go to the proper officer for approval.
  • Non-core fields: everything else in the application. For these, the registration stands amended as soon as you submit REG-14. No officer looks at it first.

If you are unsure what you declared in the first place, the online GST registration walkthrough goes through the REG-01 fields that REG-14 later edits.

Core and non-core fields, field by field

The table below is the practical version of Rule 19. The documents column lists what is typically asked for; the portal's upload prompts are the final word for your constitution of business.

Common GST registration amendments, whether they are core or non-core, and what approval and documents they need.

Two details are easy to miss. First, Rule 19 provides that an approved change to the legal name or to the persons in charge carries across to every registration you hold on the same PAN, so a company with GSTINs in several states does not amend the name state by state. The guide to multiple GST registrations on one PAN explains how those GSTINs relate. Second, addresses do not carry across: each state registration has its own places of business, and each is amended in its own registration.

The trade name deserves one caution. In law it sits outside the Rule 19(1)(a) list, so it is non-core, but the portal has moved fields between screens over the years. Check which amendment tab carries it on gst.gov.in when you file. If you are not sure how the two names differ, see legal name versus trade name on a GSTIN.

Changes that need a new registration instead

REG-14 edits an existing registration. It cannot turn one taxpayer into another, and the GSTIN itself encodes two things that define the taxpayer: the state code in its first two digits and the PAN in the next ten. Change either and you are no longer amending.

Change of PAN. A proprietor who incorporates a company, a partnership that converts to an LLP, a firm that becomes a private limited company: each ends up with a new PAN, and Rule 19 routes that case to a fresh application in REG-01. The old registration is then cancelled, and unutilised input tax credit can move across when the conditions for transfer on amalgamation, sale or change in constitution are met. The mechanics are in what happens to a GSTIN when the constitution changes.

Not every constitution change creates a new PAN. A partnership that admits or retires a partner usually keeps its PAN, and that is a core amendment rather than a new registration.

Change of state. GST registration is state-wise. If the principal place of business moves from one state to another, you register in the new state and cancel the old registration; the address field cannot be edited across a state boundary. Keeping business in both states means holding two registrations.

Filing REG-14 on the portal, step by step

Both amendment types start from the same menu. The screen labels below reflect the portal's long-running layout; the navigation has been adjusted before, so follow the nearest equivalent if a label differs.

  1. Log in to gst.gov.in with the registration's credentials.
  2. Go to Services → Registration and choose Amendment of Registration Core Fields or Amendment of Registration Non-Core Fields. If you are making both kinds of change, file them as separate applications.
  3. Open the tab for the section you are changing (business details, promoters or partners, principal place of business, additional places of business, authorised signatory, goods and services, bank accounts) and edit the field.
  4. For core fields, enter the date of the change and the reason. The date matters: it is the anchor for the 15-day filing window and for when the amendment takes effect.
  5. Upload the supporting documents the tab asks for.
  6. On the verification tab, tick the declaration, choose the authorised signatory, and sign with a digital signature certificate or EVC. Companies and LLPs must sign with a DSC.
  7. Note the ARN. Track it under Services → Registration → Track Application Status.

Adding a new promoter or partner may also trigger Aadhaar authentication for that person, in the same way it does at registration. Make sure the person is reachable on the mobile number and email you enter, because the authentication link goes there.

After you file: REG-03, REG-15 and deemed approval

For a non-core amendment, there is nothing more to wait for. The registration stands amended on submission.

For a core amendment, Rule 19 gives the proper officer 15 working days from receipt of the application to act. Three outcomes are possible.

  • Approval. The officer approves the amendment and issues an order in Form GST REG-15 on the portal.
  • A query. If the officer thinks the amendment is not warranted or the documents are incomplete or incorrect, a notice in Form GST REG-03 is issued within the same 15 working days. You reply in Form GST REG-04 within 7 working days of the notice. The officer then approves, or rejects the application with reasons in REG-05.
  • No action. If the officer does nothing within 15 working days of the application, or within 15 working days of your reply to a query, the rule provides that the registration stands amended to the extent applied for.

Most rejections come from the same small set of document problems that sink fresh applications: an unsigned rent agreement, a utility bill in a different name, an address proof that does not match the address typed on the form. The list of common GST registration rejection reasons applies almost unchanged to core amendments.

The amended certificate and your counterparties

Once a core amendment is approved, the portal makes an amended registration certificate in Form GST REG-06 available. It sits alongside earlier versions under Services → User Services → View/Download Certificates. The certificate download guide covers the page and how to tell the current version from older ones.

Replace the certificate displayed at each place of business with the amended one; Rule 18 of the CGST Rules requires the certificate and GSTIN to be displayed there. Then work outward:

  • Update the name and address on your invoice templates, because recipients match on them.
  • Send customers and suppliers the amended certificate so their vendor master reflects the new details.
  • Pull the corrected details into the e-way bill and e-invoice systems where they do not refresh automatically.

The same applies in reverse when a supplier amends. A vendor master built from a PDF certificate collected at onboarding does not update itself. Re-verifying the GSTIN against the live record is the only way to catch a changed legal name or address. The GSTIN API returns the current registration details and the GSTR filing history in one call, at ₹0.50 per verification, so a periodic check on your vendor list costs very little next to a mismatched invoice.

Frequently asked questions

Rule 19 of the CGST Rules requires the application in Form GST REG-14 to be filed within 15 days of the change. The clock runs from the date the change happened in the real world, such as the date a new director was appointed or the date you moved premises, not from the date you noticed the registration was out of date.
The rule gives the proper officer 15 working days from receipt of the REG-14 application to approve it or raise a query in Form REG-03. If the officer does neither within that window, Rule 19 provides that the registration stands amended to the extent applied for. A query restarts the practical timeline, because the officer then has a fresh window after your reply.
No. The GSTIN is built on the PAN, so a different PAN means a different taxpayer. If a proprietorship becomes a company or a partnership becomes an LLP, you apply for a new registration under the new PAN and cancel the old one; you do not amend.
Under Rule 19 the core fields are the legal name, places of business and the persons responsible for day-to-day affairs, so a trade name change falls outside that list and is treated as non-core. The portal screens have changed over time, so confirm on gst.gov.in which tab currently carries the trade name field before you file.
Through a non-core amendment of the authorised signatory details, and the change goes through only after the new mobile number and email are verified by OTP on the portal. If you have lost access to the registered contacts and cannot log in, approach your jurisdictional officer, who can update them on your application.
Generally no. A cancelled registration cannot be amended, and a suspended one usually needs the underlying issue resolved first. If the registration has been cancelled, the route back is revocation of cancellation, not REG-14.
