Mandatory e-payment of non-GST taxes shifts to the department portal as bank portal payment options are discontinued. Mandatory e-payment of taxes other than GST must be made through the department's portal integrated with GRAS. Registered taxpayers are required to use the Assam taxation portal for electronic payment, with access through existing credentials, an online dealer profile, or the jurisdictional officer. The earlier facility of payment through the banks' portals of specified banks is discontinued from 1 October 2020, and taxpayers must shift to the department's portal. A helpdesk is available for guidance and payment-related issues.
