Under Section 48 of the CGST Act, 2017, you’re permitted to authorise qualified professionals, including chartered accountants, company secretaries, cost accountants, or advocates, to handle your GST matters.

Why Is a Letter of Authorisation Required Under GST?

Importance of LOA

The letter of authorisation for GST plays a crucial role in establishing legal accountability within the GST framework. When you authorise someone to handle your tax matters, you’re creating a formal chain of responsibility that’s recognised by tax authorities. This document ensures that only designated individuals can access sensitive tax information and make decisions that affect your compliance status.

Your business benefits from professional representation through proper authorisation in several ways. Expert guidance helps navigate complex GST regulations, reducing the risk of non-compliance penalties. The authorisation also creates a clear audit trail, documenting who performed specific actions on your behalf. This transparency becomes invaluable during assessments or investigations, as you can demonstrate that qualified professionals managed your tax affairs.

The GST department requires this authorisation to verify the legitimacy of individuals claiming to represent your business. Without proper documentation, tax authorities won’t engage with third parties regarding your confidential tax matters, potentially causing delays in critical compliance activities.

Situations Where LOA Is Mandatory

  • New GST registration
    • GST number amendment
    • Changing authorised signatory
    • Responding to GST notices
