ITAT Chennai Clarifies Section 115BBE Scope and Mandates Algorithmic Consistency in Rectification Proceedings - 2026-06-06

Searching for Logic: How the ITAT Chennai Protected Assessee Rights Against Inconsistent Tax Assessments

In a significant ruling for taxpayers, the Income Tax Appellate Tribunal (ITAT) Chennai Bench has reinforced two critical principles: the requirement for consistency in tax assessment methodologies and the prospective nature of the higher tax rates introduced by Section 115BBE. The Tribunal, presided over by Vice President Shri George George K and Accountant Member Shri Amitabh Shukla, set aside lower authority orders that failed to account for established patterns in calculation and applied stringent tax rates retrospectively.

The Background: When Numbers Don’t Add Up

The dispute originated from a search and seizure operation conducted on the premises of the taxpayer, who was engaged in a money-lending business. Following the search, the Assessing Officer (AO) completed assessments for the years 2015-16, 2016-17, and 2017-18.

The taxpayer challenged the AO’s calculation of "unexplained investments" for the 2017-18 assessment year, arguing that the department had inexplicably abandoned the computational algorithm used in previous years. While the AO initially invoked proceedings under Section 154 to rectify what he perceived as a misreporting of figures, the taxpayer argued that the AO himself had committed a manifest error by failing to apply the consistent methodology used in the prior two years.

A Tug-of-War Over Tax Rates

The proceedings further delved into the hot-button issue of the 60% tax rate prescribed under Section 115BBE. The Revenue department sought to apply this higher levy to transactions that occurred before the amendment’s effective date of April 1, 2017. The taxpayer, citing the timing of the search and original financial transactions, maintained that the 30% rate should prevail.

Key Observations: The Tribunal’s Logic

The Tribunal’s decision underscored that administrative consistency is not merely a courtesy, but a requirement in tax law. Regarding the mathematical discrepancy, the ITAT observed:

> "The revenue is not entitled to change its stand haphazardly. The Algorithm adopted by the ld AO for AY 2015-16 and AY 2016-17 has to be applied for AY 2017-18 also and can not be changed."

Further, the bench highlighted the error in the AO’s refusal to rectify the calculation:

> "The impugned mistake of the Ld.AO is totally rectifiable under section 154 of the Act. Pertinently, the Ld.AO passing order for all the three assessment years is one and same and hence there cannot be any argument of a different application of mind."

Addressing the Section 115BBE application, the Tribunal relied heavily on recent precedent set by the Madras High Court:

> "It is evident that the government is intended to impose the same for future transactions... This Court is of the considered opinion that the revenue is empowered to impose 60% rate of tax for the transactions from 01.04.2017 onwards and not prior to the said cut-off date."

The Verdict: A Path to Rectification

The ITAT Chennai has allowed the assessee's appeal, explicitly directing the AO to conduct a limited verification and recalculate the tax liability. The Tribunal mandated that the AO adopt the methodology that had been consistently applied in 2015-16 and 2016-17.

Furthermore, by invoking the ruling from S.M.I.L.E Microfinance Ltd. , the Tribunal firmly closed the door on the retrospective application of the 60% tax rate, mandating that the 30% rate be applied to income determined under Section 69B for the relevant transactions. This decision serves as a timely reminder that systemic efficiency and consistency remain fundamental planks of fair tax administration.
