Calcutta High Court Upholds ₹752 Crore Tax Relief for Syama Prasad Mookherjee Port

The Calcutta High Court on 21 August 2026 upheld the deletion of tax disallowances totalling over ₹752 crore from the assessment of Syama Prasad Mookherjee Port , Kolkata (formerly Kolkata Port Trust), dismissing the Revenue's appeal against the Income Tax Appellate Tribunal (ITAT) order for Assessment Year 2018-19.

A Division Bench of Justices Rajarshi Bharadwaj and Uday Kumar ruled that extraordinary contributions to approved superannuation and gratuity funds made to meet actuarial shortfalls cannot be treated as ordinary annual contributions subject to prescribed limits. The Court also held that the port trust's specific regulations under the Major Port Trusts Act do not prescribe a due date for depositing employees' contributions, making the disallowance under Section 36(1)(va) inapplicable.

Three Major Disallowances Under Challenge

The case arose from a scrutiny assessment in which the Assessing Officer determined the port's total income at around ₹876.17 crore , incorporating three major additions:

  • ₹710.68 crore – Superannuation Fund contributions in excess of the 27% ceiling under Rule 87
  • ₹33.11 crore – Gratuity Fund contributions in excess of the 8.33% limit under Rule 103
  • ₹8.38 crore Belated credit of employees' contributions to PF/ESI under Section 36(1)(va)

The CIT(A) deleted all additions, and the ITAT upheld the relief relying on earlier Calcutta High Court decisions. The Revenue appealed under Section 260A, arguing that the port's practice of funding shortfalls was regular and not exceptional.

Actuarial Contributions Not Subject to Rule Ceilings

On the superannuation and gratuity fund issues, the Court drew a clear distinction. The port had made payments to bridge the gap revealed by actuarial valuations—a persistent deficit caused by past funding constraints. The Revenue contended that similar payments had been made for several years, converting them into regular contributions. The Court rejected this argument, observing:

"The legal nature of a contribution is defined by its purpose i.e., remedying an actuarial deficit and not by how many years the deficit takes to be fully addressed. A persistent deficit caused by past funding constraints cannot convert ad hoc gap-filling payments into ordinary annual contributions ."

On the gratuity fund, the Court noted that Section 36(1)(v) does not itself impose the 8.33% ceiling found in the Rules. Once the Commissioner had approved the fund, the Assessing Officer lacked jurisdiction to go behind that approval. It cited the precedent in Eastern Equipment & Sales Ltd , holding that the officer cannot sit in judgment over the Commissioner's approval.

No Due Date Under Port Trust Regulations for PF/ESI

On the ₹8.38 crore disallowance, the Revenue argued that employees' contributions had been deposited after the due date of the 15th of the month. However, the Court found that the Kolkata Port Trust (Non-contributory Provident Fund) Regulations 1988 , notified under the Major Port Trusts Act, do not specify any due date for depositing the employees' share. The 15th date in the Tax Audit Report was merely an artificial date generated by the e-filing software.

"In the absence of a legally prescribed due date under the applicable regulatory regime, the statutory trigger for disallowance under Section 36(1)(va) does not arise. Without a legally defined due date, there can be no delay to trigger a disallowance under Section 36(1)(va) ."

The Court also noted that the deposits were actually made within a couple of days of the software-generated deadline, further supporting the assessee's case.

Answering All Questions in Favour of Assessee

The Court answered substantial questions of law (1), (2), (3), and (5) in the negative—against the Revenue and in favour of the port—and question (4) in the affirmative, also against the Revenue. It held that the ITAT's order was not perverse, as it relied on binding jurisdictional precedents.

The appeal was dismissed with no order as to costs, preserving the ₹752 crore relief for the Kolkata port trust and reinforcing the principle that actuarially driven contributions to approved funds are not limited by routine rule ceilings.
