GST Registration Amendment Services in India
Core & Non-Core Field Changes via Form GST REG-14

A GST registration amendment is the formal correction or update of the information held against a GSTIN, carried out on the common GST portal under Section 28 of the CGST Act 2017. It is the legal route to keep registration particulars accurate after the original enrolment. The amendment is filed in Form GST REG-14, and depending on the field being changed, the update is either auto-approved or approved by a GST officer.

Every amendment combines a few defined elements — the change must relate to a particular that the law permits to be amended, the application is filed in Form GST REG-14 within the prescribed time, and the field being changed decides the route. A core field needs officer approval, while a non-core field is auto-approved. Correct classification of the change is the foundation of a clean amendment.

Section 28 of the CGST Act 2017, read with Rule 19 of the CGST Rules 2017, governs the amendment of registration. For a core field, the officer examines the request and, if satisfied, issues an approval order in Form GST REG-15. For a non-core field, the portal updates the record without officer intervention. This route is distinct from fresh GST registration and from cancellation of registration. Our service also connects with the wider indirect tax framework and ongoing GST return filing — so every client receives one structured GST compliance engagement.

Every GST registration amendment falls into one of two categories. Identifying the category correctly decides whether the change is auto-approved or sent to a GST officer for approval.

Core Field Amendments

Core fields are the particulars that materially identify the business. A change to the legal name of the business, the principal place of business, an additional place of business, or the promoters, partners, and authorised signatory is treated as a core field amendment. The officer examines the application and, if satisfied, issues an approval order — so supporting documents must be accurate, because the request is reviewed before approval.

Non-Core Field Amendments

Non-core fields are particulars that can change without affecting the legal identity of the business. A change to the trade name, bank account details, business activity, or HSN and SAC details is treated as a non-core field amendment. These updates are auto-approved on the portal without officer intervention — a non-core amendment is faster, although the details must still be entered correctly.

Amendments to Email and Mobile Number

A change to the email address or mobile number of the authorised signatory follows a separate route — it is updated directly on the portal through OTP verification rather than through the standard core or non-core amendment. This is the simplest change, but it should be done promptly because every departmental alert is sent to the registered contact.

A GST registration amendment is not optional once a registered detail changes. The law requires the business to report the change within a fixed window from the date the event occurs.

Events That Trigger a Mandatory Amendment

The Time Limit for Filing an Amendment

Section 28 of the CGST Act 2017, read with Rule 19 of the CGST Rules 2017, requires the amendment application to be filed within fifteen days of the change. The fifteen-day clock starts from the date the event occurs, not from the date the business decides to act — so prompt filing is essential to stay compliant and avoid a mismatch between the GST records and the business.

Changes That Cannot Be Made Through an Amendment

Some changes are outside the scope of a GST registration amendment. A change in the PAN of the business cannot be amended — it requires fresh GST registration. Similarly, shifting the business to a different State requires a new registration in that State and cancellation of the old one. A conversion of constitution that changes the PAN, such as a proprietorship becoming a company, also needs fresh registration rather than an amendment.

A change of business address is one of the most common reasons for a GST registration amendment. It deserves careful handling, because the treatment depends entirely on whether the new address is within the same State.

Change of Principal Place of Business Within a State

Where the business shifts its principal place of business within the same State, the change is handled as a core field amendment. The application carries fresh address proof for the new premises and is approved by the officer — so the existing GSTIN continues, and only the registered address is updated.

Shifting the Business to Another State

Where the business moves to a different State, an amendment is not enough. The business must obtain a new GST registration in the new State, because a GSTIN is State-specific, and then apply for cancellation of the old registration. An inter-State shift is a registration-plus-cancellation exercise, not a simple amendment.

Changes in the people behind a business are core field amendments. The addition, retirement, or replacement of a partner, director, or authorised signatory must be reported through Form GST REG-14 within the prescribed time.

Adding or Removing Partners and Directors

When a partnership admits or retires a partner, or a company changes its directors managing day-to-day affairs, the registration must be amended. The application carries the PAN, Aadhaar, photograph, and consent of the incoming person — so the GST records continue to reflect the people actually responsible for the business.

Changing the Authorised Signatory

The authorised signatory is the person who acts for the business on the GST portal. When this person changes, a core field amendment is filed with a board resolution or authorisation letter and the identity documents of the new signatory — so the new signatory can validly file returns and applications without portal errors.
