GST REG-14 explained: changing your registration details

Core and non-core fields

Rule 19 splits amendments into two types. Core fields need approval by the proper officer, who decides within 15 working days. Non-core fields are updated automatically on filing, without officer approval.

• Core: legal name of business where PAN does not change
• Core: address of the principal place of business or an additional place
• Core: addition or deletion of partners, directors, Karta or managing committee members
• Non-core: trade name, business activities, bank accounts, authorised signatories, contact details

Time limits

The amendment must be filed within 15 days of the change. For core fields, if the officer neither approves nor issues a REG-03 query within 15 working days, the amendment is treated as approved. If a query is raised, reply in REG-04 within 7 working days. Approval is communicated in REG-15; rejection is passed in REG-05.

What REG-14 cannot do

A change in PAN, for example when a proprietorship becomes a company or a partnership is converted into an LLP, needs a fresh registration, not an amendment. Similarly, a business moving its principal place to another state needs registration in the new state. Mobile number and email of the primary signatory are changed through a separate OTP-based process.

Practical tips

• Upload address proof that matches the new address exactly
• For a new partner, upload the amended deed and the partner's details
• Check that the effective date of change is entered correctly
• Update bank details promptly to stay compliant with Rule 10A

Help with amendments

Core amendments trigger the same document scrutiny as a new registration. A professional can prepare the application and respond to any officer query.
