Section 16(5) Non-Obstante Clause Overrides Section 16(4) Deadlines, Validating Delayed Input Tax Credit Claims

Issue

Whether the subsequently introduced non-obstante provision under Section 16(5) overrides the standard statutory time limits of Section 16(4), thereby validating Input Tax Credit (ITC) claims for the financial year 2018-19 if the corresponding monthly returns were furnished on or before the relaxed cut-off date of November 30, 2021.

Facts

  • The petitioner is a registered GST taxpayer who claimed Input Tax Credit (ITC) for the financial year 2018-19.

  • The department’s Show Cause Notice (SCN) recorded that the petitioner’s monthly returns for April 2018 to March 2019 were furnished on November 27, 2019, and November 28, 2019.

  • The Revenue passed an adjudication order declining the ITC on the grounds that these monthly returns were not submitted within the strict statutory time limits prescribed under Section 16(4).

  • The petitioner filed a writ petition challenging the denial, asserting their right to the credit under a later-inserted provision containing a non-obstante clause.

  • This newly inserted provision, Section 16(5), explicitly permitted ITC claims for such periods provided the returns were furnished on or before November 30, 2021.

Decision

  • Held, yes: The subsequently introduced Section 16(5) explicitly allows ITC claims for past periods as long as the relevant returns were furnished on or before the cut-off date of November 30, 2021.

  • Held, yes: The petitioner’s returns were filed on November 27 and 28, 2019, which sits comfortably before the statutory relaxed cut-off deadline.

  • Held, yes: Because Section 16(5) contains a powerful non-obstante clause directed at Section 16(4), the restrictive timelines of the older section lose all significance once the conditions of Section 16(5) are satisfied.

  • Held, yes: The petitioner is fully entitled to relief; the original claim rejection order is quashed, and the department is directed to reconsider and grant the benefit of Section 16(5) if the petitioner is otherwise eligible.

Key Takeaways

  • Legislative Overrides Erase Past Defaults: A non-obstante clause in a newly enacted subsection (like Section 16(5)) completely strips older restrictive clauses (like Section 16(4)) of their power to block a tax benefit, effectively wiping out the “delayed filing” taint.

  • Retrospective Relief Windows: Section 16(5) acts as a specialized amnesty window designed by the legislature to protect taxpayers who missed initial filing deadlines but managed to clear their compliance backlogs before November 30, 2021.

  • Conditional Merits Re-evaluation: While a court will quash a flat denial based on limitation deadlines when Section 16(5) applies, the department retains the right to verify if the ITC claim satisfies all other standard, non-time-related statutory eligibility criteria.

WP (C) NO. 16984 OF 2026

JUDGMENT
1. The petitioner, a registered taxpayer under the provisions of the CGST/KSGST Act has approached this Court being aggrieved by Ext.P2 order passed under Section 73(9) of the CGST Act. As per the said order the Input Tax Credit claimed by the petitioner pertaining to the assessment year 2018-2019 was declined on the reason that the petitioner failed to submit the monthly returns for the period from April 2018 – March 2019, within the statutory period contemplated under Section 16(4) of the Act.
2. The challenge is raised by the petitioner mainly placing reliance upon Section 16(5) of the Act, which was introduced subsequently, where it is contemplated that, in case the taxpayer is furnishing the returns on or before 30.11.2021, such taxpayer shall be entitled to get the Input Tax Credit. It is discernible from Ext.P1 show cause notice that, the petitioner had submitted the returns for the months of April 2018-March 2019 on 27.11.2019 and 28.11.2019. Thus, it is evident that the petitioner has submitted the returns before the cut off date contemplated under Section 16(5) of the Act and thus the petitioner is entitled to the benefits of the same. This is particularly because, Section 16(5) contemplates a non-obstante clause as regards Section 16(4), and hence if the taxpayer is submitting the return within the cut-off date contemplated under Section 16(5), the timeline fixed in Section 16(4) loses its significance. Therefore, the petitioner is entitled to the relief sought for.
Accordingly, this writ petition is disposed of, quashing Ext.P2 with a direction to the 1st respondent to reconsider the matter and grant the benefit of Section 16(5) of the Act to the petitioner, if the petitioner is otherwise entitled.
