What are Core and Non-core fields in GST Registration details?

The fields of a GST registration application are classified as core and non-core fields. Through this, the taxpayer can identify and know whether or not a particular field being amended requires the jurisdictional tax official’s approval for amendment, if it happens to be a core field. Whereas, amendment of non-core fields are automatically approved once the amendment application is filed. However, in the case of core fields, if the tax officer does not approve within a stipulated time period, then it is considered automatically approved.

Core fields are as follows:

  • Business name, (Legal Name) if there is no change in PAN
  • Principal and additional places of business (other than any change in the State)
  • Addition or deletion of stakeholders such as promoters or partners or Karta or Managing Committee or CEO

Non-core fields are as follows:

The rest of the fields other than the core fields, mentioned above, will be called the non-core fields under GST. These include:

  • Addition or deletion or modification of bank details
  • Business details
  • Description of goods and services
  • Editing state-specific information (Not being any change of State)
  • Authorised signatories or representatives
  • Modifying details of existing stakeholders such as promoters or partners or Karta
  • Minor modifications in existing principal and additional places of business

Note that for change to the mobile number or e-mail address of the authorized signatory, simply submit the form GST REG-14 and verifying online through the GST portal.

The difference between the core fields and non-core fields is as follows:

Core FieldsNon-core Fields
Requires Tax official’s verification and approvalDo not require Tax official’s approval

Can the PAN number and State be changed or updated?

No, the PAN number cannot be changed for a particular GST registration. In this case, there is any mistake in the PAN number or a change in the PAN due to a change in the constitution of business (like proprietor to partnership). Then, the applicant will have no other choice except to file for a fresh registration using the form GST REG-01.

It is because the GSTIN number is based on the PAN and GSTIN gets changed. Likewise, if there is a change in the principal place of business from one State to another, GSTIN gets modified. Therefore, it also requires the cancellation of existing registration and application for a new GST registration.

What is the process of changing or updating the GST registration details?
