Tripura HC: CGST Authorities Cannot Probe Matters Already Under State GST Adjudication

The High Court of Tripura has strictly enforced the statutory bar against parallel tax investigations, ruling that Central GST authorities lack jurisdiction to initiate proceedings on subject matters already being adjudicated by State GST wings. In a significant intervention for taxpayer protection, the Court held that the formal commencement of adjudicatory proceedings by one administration serves as a jurisdictional embargo against the other, preventing double jeopardy in tax litigation.

A bench comprising Chief Justice M.S. Ramachandra Rao and Justice Biswajit Palit heard a challenge against a Demand-cum-Show Cause Notice and a subsequent Order-in-Original issued by the Joint Commissioner, Central GST Commissionerate, Agartala. The petitioner contended that the central authorities had overstepped their jurisdiction by initiating proceedings for financial years already scrutinized by State GST (SGST) authorities, while also challenging the initiation of proceedings for the 2017-18 period as being time-barred under Section 74(10) of the Central Goods and Services Tax Act, 2017.

The Jurisdictional Bar and Parallel Proceedings

The Court focused on the interplay between Central and State authorities under Section 6(2)(b) of the Central Goods and Services Tax Act, 2017. It observed that once SGST authorities had initiated proceedings regarding mismatches in Input Tax Credit (ITC), the CGST authorities were prohibited from probing the same specific infraction. However, the Court clarified that this bar only applies to the 'same subject matter' and does not prevent the CGST department from investigating distinct issues, such as short payment of GST, which were not part of the state-level proceedings.

Regarding the limitation period for the 2017-18 financial year, the Court rejected the Revenue's argument that extension notifications for filing returns also automatically extended the limitation for departments to initiate recovery proceedings. The Court, in its reasoning, observed: "In our opinion, this notification is intended for the benefit of assesses, if they had not already filed their annual return for 2017-18 financial year by 31.12.2018. This notification is not intended to benefit the respondent CGST department, and extend for their benefit the time limit prescribed in Section 74(10) of the Act of 2017 to initiate proceedings beyond the period of 5 years from the date of filing of the annual return for 2017-18 i.e., beyond 31.12.2023."

Court Directions

The Court has the following directions:

"we set aside the show cause notice dt.22.07.2024 to that extent and the Order-in-Original dt.03.02.2025 passed by the respondent No.5 in its entirety, and remit the matter back to the respondent No.5 to pass a fresh order within 3 months only on the aspects which he is entitled to do as per this Order after hearing the petitioner afresh. All consequential actions/orders of respondents are also set aside. The petitioner is granted liberty to contend before respondent No.5 that the conditions precedent for invoking Section 74 do not exist by filing additional reply to the show cause notice within 6 weeks from today."

Background:

The dispute arose when the Joint Commissioner of Central GST issued a Demand-cum-Show Cause Notice on July 22, 2024, covering financial years 2017-18 to 2020-21. The petitioner challenged this on two primary grounds. Firstly, for the year 2017-18, the five-year limitation period under Section 74(10) had expired. Secondly, for 2018-19 and 2019-20, the SGST authorities had already issued notices regarding ITC mismatches (proceedings that were later dropped), making the parallel CGST action illegal under Section 6(2)(b). The Revenue argued that COVID-19 related extensions and administrative notifications permitted their action. However, the Court relied on the precedent set in M/s Armour Security (India) Ltd. v. Commissioner, CGST, Delhi East Commissionerate & Another ( "Special Leave Petition (C) No.6092 of 2025 dt.14.08.2025": 2025 CaseBase(SC) 674) to define what constitutes 'initiation of proceedings' and 'same subject matter'.

Key Takeaways:

Limitation Protection for Taxpayers

Extensions granted for taxpayers to file returns cannot be weaponized by the Revenue to extend the statutory five-year limitation period for initiating fraud-based recovery actions.

Prohibition of Double Jeopardy

Section 6(2)(b) of the Central Goods and Services Tax Act, 2017 acts as a mandatory pre-condition; if one tax administration (Central or State) has issued a show cause notice on a specific tax liability, the other cannot initiate a parallel inquiry on that identical liability.

Defining 'Subject Matter'

While parallel proceedings are barred for the same infraction, different tax obligations (like 'short payment' vs 'ITC mismatch') for the same financial year may still be pursued by different authorities if they constitute distinct infractions.

Ratio Decidendi:

The formal commencement of adjudicatory proceedings through a show-cause notice by either the Central or State tax administration creates a jurisdictional bar under Section 6(2)(b) of the Central Goods and Services Tax Act, 2017 against the other administration regarding the same subject matter. Furthermore, the five-year limitation period under Section 74(10) must be calculated from the original due date of the annual return, and administrative extensions for taxpayer compliance do not automatically extend the department's window for initiating recovery proceedings.
