The ITAT Ahmedabad has delivered a significant clarification on the limits of discretionary disallowance in income tax assessments, reinforcing that arbitrary adjustments without factual or comparative justification violate fundamental principles of natural justice. This ruling provides critical guidance to taxpayers and assessing officers alike on the necessity of reasoned, evidence-based assessments under Section 143(3).
Background & Facts
The Dispute
The assessee, Sundaram Roadlines, is a transportation firm that incurs substantial cash-based expenses for truck rentals. For Assessment Year 2015-16, it claimed Rs.7,04,00,166 as truck rent expenses, of which Rs.1,02,93,061 represented unpaid rent as of March 31, 2015. The Assessing Officer (AO) made an ad hoc disallowance of 20% of the total truck rent expenses, amounting to Rs.1,40,80,033, and separately disallowed the unpaid rent of Rs.1,02,93,061. This resulted in double counting of the unpaid portion, as it was included within the total truck rent figure.
Procedural History
- 2015: Assessee filed return declaring income of Rs.13,01,830.
- 2017: AO issued show cause notice seeking evidence for cash-based truck rent payments.
- 2017: Assessee submitted invoices, registration certificates, and payment details via letter dated December 20, 2017.
- 2017: AO passed assessment order without verifying submitted documents or invoking Section 133(6) to cross-check third-party records.
- 2025: CIT(A) confirmed the AO’s order after seeking a remand report, which the AO reiterated without fresh inquiry.
- 2026: Appeal filed before ITAT Ahmedabad.
Relief Sought
The assessee sought deletion of the ad hoc disallowance and the separate addition for unpaid rent, arguing that the AO had previously allowed only a 2% disallowance for identical facts in A.Y. 2013-14, and that the current action lacked consistency, reasoning, or statutory basis.
The Legal Issue
The central question was whether an Assessing Officer can impose an ad hoc disallowance of truck rent expenses under Section 37(1) without conducting a proper inquiry under Section 133(6), without rejecting the books of account, and without providing a comparative rationale when a consistent, lower rate had been applied in a prior year for identical business practices.
Arguments Presented
For the Petitioner
Shri Tushar Hemani, Sr. Advocate, argued that the AO’s 20% disallowance was arbitrary and violated the principles of natural justice. He emphasized that:
- The assessee had submitted documentary evidence including invoices and truck registration certificates.
- The AO failed to verify these documents or issue notices under Section 133(6) to third parties.
- In A.Y. 2013-14, the same AO had allowed only a 2% disallowance after a detailed analysis of the nature of the transportation business and cash flow patterns.
- The disallowance of unpaid rent separately, while including it in the total truck rent base, amounted to double taxation.
- Precedents in Principal Commissioner of Income Tax v. R.G. Buildwell Engineers Ltd. and Forum Sales (P) Ltd. support the requirement of reasoned orders and rejection of ad hoc adjustments.
For the Respondent
Shri Nitin Kulkarni, Sr. DR, defended the AO’s order, contending that cash-based expenses are inherently suspect and that the 20% disallowance was a reasonable estimate. He argued that the assessee failed to provide complete cash books and that the CIT(A) had rightly upheld the addition. No specific statutory provision was cited to justify the 20% figure.
The Court's Analysis
The ITAT emphasized that ad hoc disallowances cannot be a substitute for proper scrutiny. The Tribunal noted that the AO had not invoked Section 40A(3) or rejected the books of account under Section 145(3), nor had he conducted any verification under Section 133(6) despite having the opportunity to do so after receiving the assessee’s submissions.
"The AO made an ad hoc disallowance @20% without making any comparative cases, without calling for information under Section 133(6), and without rejecting the books of accounts."
The Tribunal found the AO’s conduct in A.Y. 2015-16 inconsistent with his own detailed order in A.Y. 2013-14, where he had accepted the nature of the business and limited disallowance to 2%. The ITAT held that consistency in assessment across years is a facet of natural justice, especially when the business model and documentation practices remain unchanged.
The Tribunal further observed that the unpaid truck rent of Rs.1,02,93,061 was already fully disallowed as a liability, and its inclusion in the 20% calculation of total truck rent led to double disallowance, which is legally impermissible. The CIT(A) failed to correct this error.
The ITAT concluded that the Revenue’s reliance on general suspicion of cash transactions cannot override the requirement for specific, evidence-based reasoning under Section 37(1). The burden of proof lies with the Revenue to demonstrate non-genuineness, not with the assessee to disprove suspicion.
The Verdict
The assessee won. The ITAT held that ad hoc disallowance without inquiry, comparative analysis, or rejection of books violates natural justice. The Tribunal directed the AO to restrict disallowance to 2% of truck rent expenses and to re-examine the unpaid rent claim with a fresh opportunity for the assessee to substantiate it.
What This Means For Similar Cases
Ad Hoc Disallowance Requires Reasoned Justification
- Practitioners must challenge disallowances based on arbitrary percentages without reference to Section 133(6), Section 40A(3), or rejection of books.
- If the AO has previously applied a lower rate for identical facts, a higher rate in subsequent years must be justified with material changes in business or documentation.
- A 20% disallowance without any supporting data is legally unsustainable.
Double Disallowance of Unpaid Liabilities Is Illegal
- Unpaid expenses already disallowed as liabilities cannot be included again in a percentage-based disallowance of gross expenses.
- Taxpayers should flag such double-counting in appeals and cite this judgment to support deletion.
Section 133(6) Is Not Optional for Cash-Based Businesses
-
For industries with high cash transactions (transport, construction, retail), the AO must either verify third-party records under Section 133(6) or formally reject books under Section 145(3).
-
Failure to do so renders the disallowance vulnerable to quashing.
-
Always request a copy of the AO’s prior year’s speaking order if it supports a lower disallowance rate.
-
File a detailed reply with invoices, bank statements, and third-party confirmations before assessment concludes.
-
Argue that natural justice requires consistency in treatment across assessment years unless there is a demonstrable change in facts.
