GST – Calcutta High Court: Appellate Authority cannot enhance tax liability without notice; Enhancement beyond show cause violates Section 107(11) [Order attached]

In the case of Lakshmi Narayan Shah v. State of West Bengal & Ors., the Calcutta High Court addressed the issue of whether an Appellate Authority can enhance tax liability on grounds not included in the original show cause notice or adjudication order, without providing the taxpayer an opportunity to respond, as required under Section 107(11) of the GST Act. The petitioner had been issued a show cause notice under Section 73 of the CGST/WBGST Act due to alleged short payment of tax related to outward and inward supply, as well as reversible ITC. However, the petitioner was unable to respond effectively because the notice was only uploaded on the GST portal.
The Appellate Authority partially allowed the appeal but unexpectedly increased the petitioner's taxable turnover by classifying an alleged excess zero-rated supply as taxable at 18%, without prior notice. The High Court found this enhancement to be in violation of the second proviso to Section 107(11) of the GST Act, as the issue of taxable turnover enhancement was not part of the original adjudication proceedings. Consequently, the appellate order was set aside to the extent it increased taxable turnover and imposed additional tax.
The matter was remanded to the Appellate Authority for limited reconsideration, requiring them to provide the petitioner an opportunity for a hearing. Additionally, the court set aside the rectification rejection order, allowing the petitioner to submit an additional reply. This decision underscores the requirement for due process and the right to be heard in tax adjudication and appellate proceedings.
