Change Trade Name or Legal Name Under GST

Businesses often need to update the name shown on their GST registration, whether because of a rebranding, a change in constitution, or a correction to the legal name recorded against the PAN. Under the GST law, both the trade name and the legal name are treated as core fields, and any change to them must be made through an amendment application in Form GST REG-14 on the common portal. This article explains what qualifies as a core field amendment, how the process works in 2026, the documents involved, and the timelines you can expect.

Trade name and legal name: understanding the difference

The legal name of the business is the name registered against the Permanent Account Number (PAN) with the Income Tax Department. The trade name, by contrast, is the brand or business name under which you actually carry on operations, and it may differ from the legal name. Both appear on the GST registration certificate, and both are classified as core fields under the amendment provisions of the GST rules.

This distinction matters because the two names are governed differently. The trade name can be changed freely through an amendment, since it is not linked to the PAN. The legal name, however, follows the PAN, and this places an important condition on how it can be revised.

Why the legal name is tied to your PAN

GST registration is PAN-based. The legal name captured in your GST record is pulled from the PAN database, so it must match the name held by the Income Tax Department. Because of this linkage, two situations arise:

1. If the legal name is being corrected or updated but the PAN itself does not change, you can file a core field amendment in Form REG-14, and the revised name will be approved by the officer.
2. If the change to the legal name is accompanied by a change in PAN, an amendment is not permitted. A change in PAN requires a fresh GST registration altogether, because the GSTIN is itself built around the PAN.

Where the name recorded on the PAN needs correction first, that update should be completed with the Income Tax Department before the GST amendment is filed, so that the two records stay consistent.

What counts as a core field amendment

Core fields are those changes that require verification and approval by the jurisdictional tax officer. They include the legal name of business (where there is no change in PAN), the addition or deletion of stakeholders such as partners, directors or the karta, and changes to the principal place of business or additional places of business within the same state. The trade name is also a core field. Amendments to non-core fields, by contrast, are processed automatically without officer intervention.

Step-by-step process to change the name in Form REG-14

The application is filed online through the GST portal. The broad sequence is as follows:

1. Log in to the GST portal with your credentials and navigate to Services, then Registration, and select Amendment of Registration Core Fields.
2. Open the relevant tab. For a legal name change, use the Business Details section; the trade name is also updated within the same section.
3. Enter the new legal name or trade name as it should appear on the registration certificate, and select the date from which the change is effective.
4. State the reason for the amendment in the field provided, as this supports the officer’s review.
5. Upload the supporting documents that justify the change, such as a board resolution, an amended partnership deed, or a revised constitution document, depending on your entity type.
6. Move to the verification tab, select the authorised signatory, enter the place, and submit the application using a Digital Signature Certificate (DSC), e-Sign, or Electronic Verification Code (EVC).
7. On successful submission, an Application Reference Number (ARN) is generated and can be used to track the status.

Documents commonly required

The exact documents depend on the constitution of the business and the nature of the change. For a name change driven by a change in constitution or an internal decision, the following are typically relevant:

1. Board resolution, in the case of a company.
2. Amended partnership deed, in the case of a partnership firm or LLP.
3. Proof of the corrected name on the PAN, where the legal name is being aligned with an updated PAN record.
4. Any certificate or order supporting the change of name, such as a fresh incorporation or name-change certificate issued by the relevant authority.

Officer approval and timeline

Because the trade name and legal name are core fields, the application does not update automatically. The jurisdictional officer examines the request and the supporting documents. If satisfied, the officer approves the amendment and an order in Form GST REG-15 is issued, after which the registration certificate is updated to reflect the new name. The GSTIN itself does not change; only the certificate is revised.

The officer is generally expected to act within fifteen working days of submission. If the officer neither approves the application nor issues a notice seeking clarification within the prescribed period, the amendment is treated as deemed approved and the certificate is updated accordingly. Where the officer needs further information, a notice in Form GST REG-03 may be issued, and you must respond in Form GST REG-04 within the time allowed. It is also worth noting that the amendment application should be filed within fifteen days of the event that caused the change.

Practical points to keep in mind

Ensure the new name matches your supporting documents exactly, since discrepancies are a common reason for queries. Keep your ongoing GST compliance in order while the amendment is pending, because filing obligations continue during this period. Once the certificate is updated, revise your invoices, letterheads, and other statutory records so that the name used across your documents remains consistent.

Frequently asked questions

Can I change both the trade name and the legal name in a single application?

Yes. Both are core fields within the Business Details section, so they can be updated together in the same Form REG-14 application, provided there is no change in PAN.

Does my GSTIN change when I change the name?

No. The GSTIN remains the same. Only the registration certificate is reissued with the updated name after the officer approves the amendment.

What happens if my legal name change involves a new PAN?

An amendment cannot be filed in that case. A change in PAN requires a fresh GST registration, since the GSTIN is derived from the PAN.

How long does approval take?

The officer is generally expected to act within fifteen working days. If no action is taken and no clarification is sought within the prescribed time, the amendment is deemed approved.

Do I need to file the amendment within a specific period?

Yes. The application should ordinarily be submitted within fifteen days of the change that gave rise to it.
