Frequently asked questions

Everything you need to know before creating your document.

Is this GST Authorised Signatory Letter mandatory for every GST registration?+

While formats may vary, GST registration generally requires that the authorised signatory be clearly identified and supported by an appropriate letter of authorisation or resolution, especially for non-individual entities such as companies, LLPs, and firms.

Do I need a separate board resolution in addition to this letter for a company?+

In practice, companies usually pass a board resolution authorising the appointment of an authorised signatory and may either attach that resolution or incorporate its reference in the letter; this template allows you to capture the internal authorisation reference while keeping the external communication concise.

Can multiple authorised signatories be covered under one letter for GST purposes?+

Yes, the template supports both single and multiple signatories; where multiple signatories are appointed, you can record each signatory’s details in the dedicated section and state whether they can act singly or jointly.

How should I handle changes to the authorised signatory on the GST portal?+

You should issue a fresh or updated authorisation letter, ensure corresponding internal approvals are in place, and then update the authorised signatory details on the GST portal in line with prescribed procedures so that GST authorities rely on the latest information.
