Five Years Later, Section 16(5) Comes Through: Gauhati HC Quashes a GST Order Because the Taxpayer Filed on Time All Along

Published 28 Aug 2026· Updated 28 Aug 2026· 7 min read

The Story

Sometimes the law catches up with a taxpayer years after the fact — in their favour, for once.

Rajib Agarwala, representing DM Services Private Limited, had filed his GST return for Financial Year 2018-19 on 23 October 2019 — well within any reasonable filing window, and, as it would turn out, exactly the kind of timing Parliament would later decide should be protected. None of that stopped an Order-in-Original dated 13 March 2024 from denying the firm’s Input Tax Credit and confirming a demand, on grounds that, at the time the order was passed, still looked defensible under the department’s reading of the CGST Act.

Agarwala challenged the order on two fronts. First, that Notification No. 9/2023-CT dated 31 March 2023, which extended the department’s time limit for issuing orders under Section 73, shouldn’t have applied to his case. Second — and this is the ground that ultimately decided everything — that the ITC shouldn’t have been denied at all, given that the return claiming it had been filed back in October 2019.

By the time the matter reached the Gauhati High Court, something had changed in the law that made the second argument far simpler than it would have been in 2024. The Finance Act, 2024 had inserted Section 16(5) into the CGST Act — a provision written specifically to fix a widely-felt unfairness from GST’s early, chaotic years, when businesses across the country missed the Section 16(4) ITC deadline not out of negligence, but because the return-filing system itself was still finding its feet. Section 16(5) draws a line: for invoices and debit notes relating to Financial Years 2017-18 through 2020-21, a taxpayer can claim ITC in any return filed up to 30 November 2021 — no matter what Section 16(4)’s ordinary deadline would otherwise have said.

Sidebar: what makes this case unusually clean, and worth quoting from directly, is that the Court’s own order does the entire analysis in barely a paragraph. It didn’t need expert argument or extended reasoning — it just laid the return-filing date next to the statutory cut-off date and read the result straight off the page.

Agarwala’s counsel made the point plainly: given Section 16(5), the whole writ petition could be resolved on that ground alone. The Court agreed, and did exactly that. It reproduced Section 16(5) in full, then turned to the one fact that mattered: per the department’s own Order-in-Original, the return for FY 2018-19 had been filed on 23 October 2019 — more than two years before the 30 November 2021 cut-off Parliament had fixed. “Under such circumstances,” the Court held, “it is therefore the opinion of this Court that the benefit of the ITC claimed amounting Rs.84,58,480/- cannot be denied in view of Section 16(5).”

The Order-in-Original was set aside and quashed in full. The interim order that had been protecting the taxpayer during the litigation was vacated — no longer necessary, since the underlying order it was shielding against no longer existed. No costs were awarded either way.

The first ground Agarwala had raised — the challenge to Notification No. 9/2023-CT’s extension of Section 73 timelines — never needed to be decided. Once Section 16(5) settled the ITC question in the taxpayer’s favour, the entire order fell, and there was nothing left in that first argument for the Court to rule on.

Why It Matters

Section 16(5) has been on the books since the Finance Act, 2024, but plenty of pre-2024 orders denying ITC for the FY 2017-18 to FY 2020-21 window are still sitting in appeal, in recovery proceedings, or simply unchallenged because the taxpayer assumed the fight was already lost. This ruling is a clean, low-complexity template for exactly that situation: if the return was filed by 30 November 2021, Section 16(5) settles the question almost mechanically, and courts are treating it that way — no extended argument required.

Key Takeaways

  • Section 16(5) of the CGST Act, 2017 (inserted by the Finance Act, 2024) entitles a registered person to claim ITC on invoices/debit notes for FY 2017-18 through FY 2020-21 in any return filed up to 30 November 2021 — overriding the ordinary Section 16(4) time limit for that specific window.
  • Where a GST order denying ITC pre-dates the taxpayer’s awareness (or the department’s application) of Section 16(5), and the underlying return was in fact filed by 30 November 2021, this is now a straightforward, largely mechanical ground to have that order set aside.
  • The Gauhati High Court disposed of this matter on the Section 16(5) ground alone, without needing to rule on a separately-raised challenge to Notification No. 9/2023-CT’s extension of Section 73 timelines — a reminder that a clean statutory ground can moot other pending arguments entirely.
  • The relevant comparison is simple and factual: the actual date the FY-specific return was filed, measured against the 30 November 2021 cut-off — not the date of any subsequent notice, order, or recovery action.
  • This ground applies specifically to the FY 2017-18 to FY 2020-21 window; it does not extend ITC relief to later financial years, which remain governed by the ordinary Section 16(4) deadlines.

Practical Implications

Every CA firm should treat this as a prompt to re-audit any client file involving ITC denial, demand, or recovery for FY 2017-18 through FY 2020-21 where the underlying return was, in fact, filed by 30 November 2021 — regardless of how old the dispute is or what stage it has reached. Given how mechanically courts are applying Section 16(5) on these facts, this is often a faster and higher-certainty route to relief than contesting the substantive merits of an ITC denial.

Action Checklist

  • Identify every client with a live or historical ITC dispute for FY 2017-18 through FY 2020-21, and check the actual filing date of the relevant GSTR-3B/annual return against the 30 November 2021 Section 16(5) cut-off.
  • Where the filing date is on or before 30 November 2021, raise Section 16(5) as a standalone, primary ground in any pending appeal, writ petition, or reply to a recovery notice — this ruling shows courts treating it as dispositive on its own.
  • For clients where an order has already attained finality (no appeal filed, limitation expired), evaluate whether a fresh writ petition citing Section 16(5) and this ruling remains a viable route, given that the statutory provision itself did not exist at the time the original order was passed.
  • Do not assume Section 16(4)’s ordinary deadline governs FY 2017-18–2020-21 disputes without first checking whether Section 16(5) independently rescues the claim.
  • Cite Rajib Agarwala v. The Union of India and 5 Ors. (Gauhati High Court) directly — the full order text is publicly available and demonstrates the straightforward, low-friction way this ground has been accepted.

FAQs

Q: Does Section 16(5) apply to GST returns for financial years after FY 2020-21?
A: No — Section 16(5) is specifically scoped to invoices and debit notes for FY 2017-18, 2018-19, 2019-20 and 2020-21, with a fixed cut-off of returns filed up to 30 November 2021. Later financial years remain governed by the ordinary Section 16(4) time limits.

Q: If a GST demand order has already become final (no appeal filed within time), can Section 16(5) still help?
A: This specific ruling arose in a writ petition rather than a finality-barred scenario, so it does not directly answer that question. Where an order has attained finality, practitioners should evaluate the availability of a fresh writ petition on the basis that Section 16(5) provides an independent statutory right that may not have existed or been considered at the time of the original proceedings — this requires case-specific assessment.

Q: Was the extension of the Section 73 time limit under Notification No. 9/2023-CT also struck down in this case?
A: No — the Court did not need to rule on that ground at all, since the Section 16(5) point independently disposed of the entire matter in the taxpayer’s favour. That challenge remains open as a separate legal question in other cases.
