<h1>GST System Update: Taxpayers Can Now Change Authorized Signatory's Contact Details with Help from Jurisdictional Tax Officers.</h1> Taxpayers have reported issues with intermediaries using their own contact details during GST registration, withholding user credentials from the taxpayers. To resolve this, the GST system now allows taxpayers to update their authorized signatory's email and mobile number with assistance from jurisdictional tax officers. Taxpayers must approach their jurisdictional tax officer with valid identity and business documents. The officer will verify and update the contact details in the GST system, reset the password, and provide new login credentials to the taxpayer. This enables taxpayers to regain control over their GST accounts.
