1. Great question — this touches on a nuanced area of natural justice and assessment procedures under Service Tax (legacy regime) and GST.
🔍 Can a Single Assessment Order Cover Multiple Years Based on One SCN?
✅ Service Tax Regime (pre-GST):
- Under Section 73 of the Finance Act, 1994 (for non-fraud cases) and Section 73A/74 (for fraud/suppression cases), a Show Cause Notice (SCN) can cover multiple years if proper details and reasoning are provided.
- Courts have upheld single SCNs for multiple periods provided:
- Each period's alleged non-compliance is clearly identified.
- The assessee is given a reasonable opportunity to respond on each year separately.
- The final assessment/adjudication order also deals with each year distinctly.
📌 Important Principle:
What is prohibited is a vague omnibus demand across years without clear justification per period. But a composite SCN and order is legally permissible if properly structured.
✅ GST Regime:
Under the CGST Act, 2017:
📜 Relevant Sections:
🧾 Key Points:
- SCNs can cover multiple financial years or tax periods.
- Rule 142(1)(a) of CGST Rules allows issuance of a consolidated SCN (Form DRC-01).
- Final order is issued in DRC-07 — again, a single order may cover multiple periods, provided it is reasoned and period-wise structured.
💡 Courts have generally held that multiple demands in one order are not invalid per se, unless they violate:
- Principles of natural justice
- Or fail to provide clear basis of demand year-wise or period-wise
⚖️ Judicial Viewpoints (Key Cases):
✅ Service Tax:
Demand is invalid if the SCN is vague and does not provide specific reasons per year or transaction.
- CCE vs Shree Rajasthan Syntex [2016-TIOL-2606-CESTAT-DEL]
Composite SCNs covering multiple years are valid if reasons per year are clearly articulated.
✅ GST:
- Madras High Court – M/s. D. Gopi vs ACST (W.P. No. 29847 of 2022)
Held that composite demand orders are permissible under Section 73/74, if proper hearing and clarity are ensured.
🧾 Summary:
| Aspect | Service Tax | GST |
| SCN for multiple years | ✅ Allowed if period-wise basis is disclosed | ✅ Allowed via DRC-01; must explain each period |
| Single assessment order | ✅ Valid if reasoned and structured | ✅ Permitted under Section 73/74, subject to fair hearing |
| Natural justice concerns | ❌ Invalid if vague or fails to provide clear reasoning | ❌ Invalid if arbitrary or without opportunity of reply |
| Judicial view | Supports single SCNs if detailed | Same view — composite order valid if fair and justified |
✅ Conclusion:
Yes, the law permits a single SCN and a consolidated assessment order for multiple years, both under Service Tax and GST, provided that:
- Each year or tax period is clearly explained,
- The noticee is given fair opportunity to respond to each charge,
And the order is reasoned and structured period-wise.
