A Procedural Question with High-Stakes Consequences
The Gauhati High Court judgment in M/s Tata Projects Limited, Assam v. Union of India and 4 Others, 2026-VIL-568-GAU, dated 08.06.2026, is an important ruling on a recurring procedural issue under GST law. The judgment was delivered in a batch of three writ petitions, namely Tata Projects Limited, Assam; Quantum Infratech Assam; and Bitchem Asphalt Technologies Limited. The common question was whether the proper officer can issue a consolidated show-cause notice covering more than one financial year under Section 73 or Section 74 of the CGST Act, 2017, and thereafter pass a consolidated order.
This question is not merely technical. In GST proceedings, show-cause notices often span long audit or investigation periods. Taxpayers generally argue that each financial year has its own annual return, its own limitation date, its own factual defence, and its own set of records. Revenue authorities, on the other hand, often prefer consolidated notices in which the same pattern of alleged short payment, incorrect availment of input tax credit, or suppression spans several years. The judgment therefore has practical significance for both taxpayers and officers.
The Gauhati High Court held that there is no express bar in the CGST Act to a consolidated show-cause notice covering multiple financial years. It also held that a consolidated order can be passed, provided the limitation requirements for each period are independently satisfied. At the same time, the Court did not say that the limitation becomes irrelevant. On the contrary, it protected the financial-year-wise limitation principle by applying the doctrine of severability. In simple terms, a consolidated notice may survive, but a time-barred year within it may still fall.
The Core Dispute: One Notice or Year-Wise Proceedings
The petitioners argued that the GST law is built around separate tax periods and financial years. Returns are filed under Section 39, and annual returns under Section 44. Books and records are maintained year-wise. The limitation under Sections 73(10) and 74(10) also refers to the due date of the annual return for the financial year to which the unpaid, short-paid tax, wrongly availed ITC, or erroneous refund relates. On that basis, it was argued that proceedings under Sections 73 and 74 must be initiated financial year-wise, and not through a single notice covering several years.
The Revenue took the opposite view. It relied on the language of Sections 73 and 74, particularly the expressions “for any period” and “for such periods”. According to the Revenue, if the law intended to prohibit consolidated proceedings, it would have said so expressly. The Revenue relied on Sections 73(3), 73(4), 74(3) and 74(4), which allow statements for other periods, to show that the statute itself contemplates proceedings extending beyond a single financial year.
The Court accepted the Revenue’s broad statutory reading. It held that the jurisdiction to issue a notice arises when the proper officer forms the required opinion under Section 73(1) or Section 74(1). Section 73 applies where the case does not involve fraud, wilful misstatement, or suppression of facts to evade tax. Section 74 applies where those serious ingredients are alleged. However, neither Section 73(1) nor Section 74(1) requires a separate notice for each financial year.
Statutory Language Favours Consolidation, Not Fragmentation
A key reason behind the decision lies in the language of the statute. Section 73(3) provides that where a notice has been issued for any period under Section 73(1), the proper officer may serve a statement containing details for such periods other than those covered by the notice. Section 73(4) then provides that such statement shall be deemed to be service of notice, subject to the condition that the grounds are the same. The corresponding structure appears in Sections 74(3) and 74(4), though Section 74(4) has its own language because fraud, wilful misstatement, and suppression are of particular relevance there.
The Court considered this language important. The terms ‘for any period’ and ‘for such periods’ do not clearly mean that notice must be limited to a single financial year. Instead, they imply a broader procedural structure. If notices can cover other periods, the law does not clearly require a separate, full show-cause notice for each financial year in every situation.
This does not imply that the department can group years informally or without proper care. The notice must remain clear and understandable. It should specify the demand, the reason behind it, the relevant timeframe, the applicable legal provisions, and the grounds for proposing tax, interest, and penalties. Consolidating multiple years should not lead to confusion. However, simply including more than one financial year does not, on its own, eliminate jurisdiction.
Limitation Remains the Guardrail for Every Financial Year
The most balanced aspect of the judgment is its treatment of limitation. The Court did not permit consolidation to override statutory timelines. It noted that Section 73(2) requires the notice to be issued at least three months before the time limit for passing the order under Section 73(10). Section 74(2) requires the notice to be issued at least six months before the time limit for passing the order under Section 74(10). Section 73(10) allows an order within three years from the due date for furnishing the annual return for the relevant financial year, whereas Section 74(10) allows five years.
These limitation provisions are specific to each financial year. If a consolidated notice spans multiple years, each year must individually meet the applicable limitation criteria. The department cannot include a year that is otherwise barred by time in a consolidated notice and claim the notice is valid just because later years are within the deadline.
Severability Protects Valid Years Without Saving Time-Barred Demands
The Court explained this through the doctrine of severability. Each financial year constitutes a separate cause of action. If one year is barred, that part can be severed from the rest. The entire consolidated notice need not automatically fail, just as a civil claim involving recurring dues may survive periods of limitation even though earlier periods are barred. This reasoning is practically useful because it avoids two extremes. It neither invalidates every consolidated notice nor allows a time-barred demand to ride on the back of a valid year.
Demand Adjudication Is Different from Assessment
Another important issue was whether proceedings under Sections 73 and 74 should be treated as assessment proceedings. The petitioners argued that, because Section 2(11) defines assessment as the determination of tax liability, proceedings under Sections 73 and 74 also form part of assessment. If that argument were accepted, the financial-year-specific structure of assessment and returns could support the conclusion that demand notices must also be year-wise.
The Court rejected this approach. It drew a distinction between assessment proceedings under Chapter XII and demand and recovery proceedings under Chapter XV. Self-assessment, scrutiny assessment, provisional assessment, best judgment assessment, and summary assessment operate within their respective statutory fields. Proceedings under Sections 73 and 74 are different. They are adversarial and adjudicatory. They begin when the proper officer believes that tax has not been paid or has been short-paid, that a refund has been erroneously granted, or that input tax credit has been wrongly availed or utilised.
Once such proceedings begin, the person chargeable with tax is given notice, an opportunity to reply, and a hearing as contemplated under Section 75. Thereafter, an adjudication order determining tax, interest and penalty is passed. This process is not the same as an ordinary assessment. It is a demand adjudication. Therefore, the financial-year-wise nature of returns and assessment provisions cannot be converted into an implied prohibition against consolidated demand notices.
Conflicting High Court Views and the Emerging Judicial Line
The issue of consolidated show-cause notices has led to differing views across the High Courts. The petitioners relied on judgments such as M/s Tharayil Medicals v. Deputy Commissioner, 2025-TIOL-828-HC-KERALA-GST = 2025-VIL-356-KER; Dhanlaxmi Bank Limited v. Union of India, 2026-TIOL-353-HC-KERALA-GST = 2026-VIL-170-KER; M/s Oriental Lotus Hotel Supplies Private Limited v. Joint Commissioner, Chennai GST Audit-II Commissionerate, 2025-TIOL-1869-HC-MAD-GST = 2025-VIL-870-MAD; Titan Company Ltd. v. Joint Commissioner of GST & C. Ex., 2024 (1) TMI 619 = 2024-VIL-19-MAD; Milroc Good Earth Developers v. Union of India, 2025-VIL-1081-BOM; Marfani Steel Impex v. Principal Commissioner, CGST & Central Excise, Nagpur, 2026-VIL-800-BOM; Aasawa Brother Corporate Avenue v. Union of India, 2026-VIL-799-BOM; and Uber India Systems Private Limited v. Deputy Commissioner of Central Tax, 2026-VIL-123-AP.
The Gauhati High Court respectfully disagreed with the Kerala and Madras views in Tharayil Medicals, Dhanlaxmi Bank, Oriental Lotus and Titan. It also noted that the Bombay High Court's line of cases in Milroc Good Earth Developers, Marfani Steel Impex and Aasawa Brother Corporate Avenue had been doubted by a Division Bench of the Bombay High Court in Rollmet LLP v. Union of India, 2026 SCC OnLine Bom 2613 = 2026-VIL-377-BOM.
The Court preferred the reasoning of the Delhi High Court in Ambika Traders through Proprietor v. Additional Commissioner, Adjudication, DGGSTI, CGST, Delhi North, 2025 SCC OnLine Del 6913 = 2025-VIL-806-DEL, and in M/s Mathur Polymers v. Union of India, 2025 SCC OnLine Del 6892 = 2025-VIL-909-DEL. It also referred to S.A. Aromatics Private Limited v. Union of India, 2026 SCC OnLine All 191 = 2026-VIL-419-ALH, and to the Karnataka authorities, including Pramur Homes and Shelters v. Union of India, MANU/KA/4378/2025 = 2025-VIL-1306-KAR, and Commissioner of Central Tax, Bengaluru v. Chimney Hills Education Society, 2026 SCC OnLine Kar 3836 = 2026-VIL-430-KAR.
The Revenue also cited Kunhayammed v. State of Kerala (2000) 6 SCC 359 = 2000-VIL-31-SC to support its argument that the Supreme Court did not interfere in Mathur Polymers. However, the Gauhati High Court's decision was primarily based on the textual and structural analysis of Sections 73 and 74, in conjunction with the overall scheme of the CGST Act.
Consolidation Cannot Dilute Clarity or Natural Justice
Although the judgment favours the validity of consolidated notices, it should not be read as undermining procedural fairness. A consolidated notice must remain sufficiently clear for the taxpayer to understand and respond to it. If different years involve different facts, transactions, or defences, the notice should clearly identify them. The taxpayer must not be left guessing which allegation applies to which year.
The Court observed that the petitioners had argued prejudice because different financial years may involve different defences. The answer of the Court was not that prejudice is irrelevant. Rather, it held that such a contention cannot remove the jurisdiction of the proper officer when the statute itself does not prohibit consolidation. If a taxpayer establishes real prejudice of a constitutional kind, that may be examined in an appropriate case. But a general possibility of inconvenience cannot create a statutory bar that the legislature has not enacted.
This distinction is crucial for officers. Consolidation should aim to simplify procedures, not obscure them. A clear, well-drafted consolidated notice should still clearly list the demand for each year, specify the nature of the default, cite the relevant provision, detail the calculation of tax, interest, and penalties, and include the supporting materials. The judgment supports the use of consolidation as an acceptable format; however, it does not endorse vague or unclear drafting.
Merits Belong to the Appellate Forum
After ruling against the petitioners on the jurisdictional issue, the Court did not address the merits of their demands. This remains an important aspect of the judgment. Issues like fraud, deliberate misstatement, or suppression of facts are factual in nature, needing review of records, responses, conduct, transactions, returns, audit materials, and evidence. As a result, the writ court found the statutory appellate authorities more appropriate for resolving these issues.
The petitioners were instructed to follow the statutory appellate processes. Tata Projects Ltd., Assam, and Quantum Infratech Assam have 30 days to file appeals with the Appellate Tribunal under Section 112, while Bitchem Asphalt Technologies Ltd. has 30 days to submit an appeal to the Appellate Authority under Section 107. If they file within this timeframe, their appeals should be considered on the merits without dismissing them due to limitation issues. The interim protection remains in effect until the stay applications are reviewed by the appellate forums.
This part of the order reflects a pragmatic balance. The Court rejected the broad jurisdictional attack on the consolidated notices but did not shut the door on factual and legal defences. The taxpayers may still contest the demands, the limitation for particular periods, the computation, the classification of allegations under Section 73 or Section 74, the penalty, and all other merits before the appropriate forum.
The Practical Takeaway: Consolidation Is Valid, but Each Year Must Stand on Its Own
The Tata Projects ruling is expected to be frequently referenced in GST disputes involving audit or investigation demands spanning multiple years. Its key point is straightforward: a consolidated show cause notice is within jurisdiction even if it covers several financial years. Similarly, a consolidated order remains valid for the same reason. The critical factors are whether the statutory criteria of Sections 73, 74, and 75 are met and if the limitation period is independently observed for each relevant period.
For taxpayers, this judgment indicates that merely challenging the notice on the grounds of it being consolidated may not be sufficient, especially in courts that adopt this reasoning. A more effective approach would involve assessing whether the notice is vague, if period-specific details are missing, whether the limitation period has expired for any specific year, if the criteria of Section 74 are correctly alleged, whether the computation is accurate, and if natural justice has been upheld.
For the department, the judgment supports consolidated proceedings, but with responsibility. Consolidation must be disciplined. It should not become a means of clubbing unrelated years, hide limitation defects, or mix different allegations in a manner that weakens the taxpayer’s ability to respond. A consolidated notice that is clear, period-wise, evidence-based, and within limitation is more likely to withstand scrutiny.
Ultimately, the judgment provides procedural clarity while maintaining statutory safeguards. It acknowledges administrative convenience but emphasises that limitations are not compromised. A proceeding can span multiple years, but each year must be based on its own legal grounds. The key takeaway of the ruling is that consolidation is allowed; however, compliance must be assessed on a year-by-year basis.
