Inter-Departmental Alignment: Harmonizing Direct and Indirect Tax Audit Trails to Safeguard Assessees
Rejection of Books Under Section 145(3): Why Search Statements Cannot Overrule Verifiable Commercial Proof
By Legal Editor
New Delhi: July 27, 2026:
The friction between tax revenue authorities and corporate assessees often peaks in disputes over the genuineness of commercial transactions. Historically, assessing officers under the Income Tax Act, 1961, have frequently relied on third-party statements, search findings, or intelligence reports from external agencies to brand purchases as bogus, fictitious, or accommodation entries. However, with the structural evolution of modern statutory frameworks—most notably the unified Goods and Services Tax system introduced via the Central Goods and Services Tax Act, 2017—the threshold of proof required to establish a bona fide commercial transaction has undergone a significant transformation.
A landmark judicial decision illustrating this shift is the ruling by the Income Tax Appellate Tribunal, Kolkata Bench, in M/s Diach Chemicals & Pigments Pvt. Ltd. v. DCIT, Central Circle 4(2), Kolkata (ITA Nos. 1469 & 1470/KOL/2025). The Tribunal adjudicated on whether purchases could be branded as non-genuine solely on the basis of statements recorded during search operations, even when corresponding sales were fully accepted and supported by comprehensive statutory GST documentation, banking channels, and physical movement logs. The ruling emphasizes that suspicion, no matter how strong, cannot replace objective evidentiary proof in tax assessments.
Statutory Architecture: Key Provisions Under the Income Tax Act, 1961
To appreciate the legal reasoning applied by the ITAT, it is essential to examine the core provisions of the Income Tax Act, 1961, that govern search proceedings, reassessments, book rejections, and business expenditure allowances.
Section 132 and Section 133A: Search, Seizure, and Survey Operations
Under Section 132, the tax department possesses broad powers to enter, search, and seize records where there is reason to suspect undisclosed income or assets. Section 132(4) empowers authorized officers to record statements on oath. While statements recorded under Section 132(4) hold evidentiary value, judicial precedent has consistently established that an uncorroborated statement obtained during a search cannot form the sole basis for an assessment addition if objective documentary evidence contradicts the oral admission.
Section 147 and Section 148: Reopening of Assessment
Section 147 empowers the Assessing Officer to assess or reassess income escaping assessment, provided the procedural conditions under Section 148, Section 148A, and associated time limits are strictly satisfied. Reassessment proceedings initiated on information received from external enforcement wings must undergo independent verification by the Assessing Officer rather than relying on automatic transcription.
Section 145(3): Rejection of Books of Account
Section 145(3) grants the Assessing Officer authority to reject the books of account of an assessee if they are not satisfied with the correctness or completeness of the accounts, or if the method of accounting or income computation standards have not been regularly followed. Rejection of books under Section 145(3) is a prerequisite before an Assessing Officer can proceed to estimate turnover or profit margins using best judgment techniques under Section 144. However, book rejection cannot be arbitrary; it requires specific, demonstrable flaws in the accounting ledger.
Section 37(1): General Business Expenditure Allowance
Section 37(1) allows deduction for any expenditure laid out or expended wholly and exclusively for the purposes of the business or profession, provided it is not personal in nature or capital in nature, and is not incurred for any purpose prohibited by law. When purchases are alleged to be bogus, the revenue essentially seeks to disallow the deduction under Section 37(1) or add the purchase value back under Section 69C as unexplained expenditure.
Cross-Statutory Synergies: The CGST Act, 2017 and Inter-Departmental Harmony
The decision highlights the necessity for conceptual consistency between direct and indirect tax laws. When assessing the validity of commercial transactions, tax authorities cannot operate in isolated silos.
Section 16 of the CGST Act, 2017: Input Tax Credit Eligibility
Section 16 of the Central Goods and Services Tax Act, 2017, dictates the conditions under which a registered person is entitled to claim Input Tax Credit on goods or services. Key conditions include:
Possession of a valid tax invoice or debit note issued by a registered supplier.
Actual receipt of the underlying goods or services.
Payment of the tax charged in respect of such supply by the supplier to the government.
Filing of periodic GST returns under Section 39.
When the GST authorities verify, accept, and allow Input Tax Credit under Section 16 after evaluating statutory filings such as GSTR-1 (details of outward supplies) and GSTR-3B (summary return), it creates a legal presumption that the movement of goods and physical supply took place.
Statutory Logistics Tracking: E-Way Bills and Weighment Logs
Under Rule 138 of the CGST Rules, 2017, every registered person who causes movement of goods exceeding the prescribed value threshold must generate an Electronic Way Bill (e-Way Bill). An e-Way Bill incorporates detail regarding vehicle numbers, transporter IDs, consignment notes, and route tracking. When backed by lorry receipts, weighment slips, and toll gate logs, the physical presence and transit of goods are established objectively, rendering claims of non-existent supplies legally untenable unless fraudulent conspiracy is explicitly proved.
Analysis of the Judicial Precedent: M/s Diach Chemicals & Pigments Pvt. Ltd.
Factual Matrix and Assessment Findings
In M/s Diach Chemicals & Pigments Pvt. Ltd. v. DCIT, the assessee was engaged in manufacturing pure lead and lead alloys, supplying products to industrial clients such as M/s Exide Industries Ltd. Following search operations under Section 132, the Assessing Officer reopened assessment under Section 147/148, alleging that purchases amounting to over ₹40 crore from seven distinct suppliers were bogus. The AO relied primarily on statements recorded during search operations, rejected the audited books under Section 145(3), applied an estimated Gross Profit rate, and made substantial income additions.
The Assessee's Evidentiary Submissions
The assessee successfully demonstrated that its operations were subject to multi-layered statutory audits, including corporate audits under the Companies Act, 2013, tax audits under Section 44AB of the Income Tax Act, cost audits, and GST compliance audits. To refute the allegation of bogus purchases, the assessee submitted supplier-wise documentation comprising:
Valid Tax Invoices and Purchase Orders.
E-Way Bills verified on the government portal.
Lorry Receipts issued by independent transport agencies.
Physical weighment slips generated at factory gates.
Matched GSTR-1 and GSTR-3B returns filed by the vendors.
Complete banking transaction trails showing payments through regular banking channels.
Legal Rationale of the Tribunal
The Kolkata Bench of the ITAT reversed the additions made by the revenue, establishing several critical legal principles:
Incongruity of Accepting Sales While Doubting Purchases: In a manufacturing concern, output yields are intrinsically tied to raw material inputs. If the Assessing Officer accepts the quantitative sales figures and manufacturing output without dispute, it is logically impossible to reject the raw material purchases necessary to produce those sold goods.
Evidentiary Weight of Indirect Tax Compliance: Where the GST department accepts the returns, allows Input Tax Credit, and verifies the e-Way Bills, the Income Tax Department cannot arbitrarily declare the same physical supplies as non-existent without leading independent, verifiable counter-evidence.
Primary Evidentiary Value of Banking Trails: Payments routed through proper banking channels create a verifiable financial chain that cannot be dismissed merely on suspicion or third-party uncorroborated statements recorded during search operations.
Broader Judicial Precedents Governing Bogus Purchases
The ruling aligns with an established line of jurisprudence across various High Courts and Tribunal Benches across India:
Conclusion and Practical Key Takeaways for Assessees
The legal discourse surrounding purchase verification underscores the growing importance of maintaining integrated, multi-statutory records. The decision in Diach Chemicals & Pigments Pvt. Ltd. reiterates that administrative suspicion cannot override documented reality. For corporate assessees and tax practitioners, the ruling highlights essential practices:
Integration of Logistics Records: Tax invoices must always be cross-referenced with corresponding e-Way bills, weighment logs, and transport bills.
Banking Discipline: All vendor settlements must be routed through non-cash, verifiable banking channels.
Cross-Tax Alignment: Compliance records under GST (GSTR-1, GSTR-2A/2B, GSTR-3B) must always remain reconciled with income tax audited financials to prevent tax additions.

Q1: What defines a 'bogus purchase' under Indian Income Tax law?
A bogus purchase refers to an entry in an assessee's books of account where an expenditure for goods or services is recorded to reduce taxable profits, but no actual goods or services were delivered by the named supplier. These are often referred to as accommodation entries provided by non-existent or shell entities.
Q2: Can the Assessing Officer reject books of account under Section 145(3) without proving specific defects?
No. The Assessing Officer cannot arbitrarily invoke Section 145(3). Rejection of books requires objective evidence that the accounting records are incomplete, incorrect, or that prescribed accounting standards were not followed. Disagreeing with vendor credentials alone is insufficient grounds to reject statutory audited accounts.
Q3: Why is it legally inconsistent for tax authorities to accept sales while declaring purchases bogus?
In trading and manufacturing operations, physical goods sold must originate from raw material purchases. If the tax department accepts the quantitative sales figures and resulting revenues, it implicitly acknowledges that goods were present and sold. Disallowing the corresponding purchases creates a factual absurdity where finished goods exist without input materials.
Q4: What evidentiary role do GST returns and e-Way Bills play in an Income Tax assessment?
GST records (such as GSTR-1, GSTR-3B, and Input Tax Credit allowances) along with e-Way Bills and transport logs serve as robust third-party documentary proof. Under the CGST Act, 2017, e-Way bills verify physical movement across state/district borders, making it exceptionally difficult for income tax authorities to claim supplies were purely paper entries without contrary physical evidence.
Q5: Can an assessment addition be made solely on statements recorded during a Section 132 search?
No. While statements recorded under Section 132(4) carry evidentiary value, they do not constitute conclusive evidence by themselves. If an assessee presents objective documentary evidence—such as tax invoices, banking receipts, and transport logs—oral statements uncorroborated by independent physical evidence cannot sustain a tax addition.
Q6: How does routing payments through banking channels impact the defense against bogus purchase allegations?
Demonstrating that payments were executed via account payee cheques, RTGS, or NEFT establishes an audit trail through regulated financial intermediaries. While a banking trail alone may not prove physical delivery, when combined with e-Way bills and weighment slips, it creates a formidable presumption of genuine commercial dealing.
Q7: What is the difference between disallowing an entire purchase vs. estimating a gross profit addition?
Disallowing an entire purchase (100% addition) treats the whole payment as fake expenditure under Section 37 or Section 69C. Conversely, a Gross Profit (GP) estimation addition assumes that while physical goods were procured, they might have been purchased from the open/unorganized market at lower rates than billed by the named supplier. In GP estimations, courts only tax the estimated profit percentage savings, rather than the full purchase value.
Case Citation / Court — Core Legal Principle Established
ITAT Kolkata (Diach Chemicals & Pigments) — Purchases supported by GST filings, e-Way bills, weighment slips, and banking trails cannot be held bogus when corresponding sales are accepted.
Bombay High Court (CIT v. Nikunj Eximp Enterprises) — Where sales are accepted by the revenue and backed by complete records, raw material purchases cannot be disallowed in entirety.
Gujarat High Court (CIT v. Simit P. Sheth) — In cases where purchases are dubious, but sales are unquestioned, only the profit element embedded in procuring goods from the open market can be added, not the full purchase price.
Supreme Court of India (Odeon Builders Pvt. Ltd.) — Assessment additions cannot be sustained solely on third-party statements obtained behind the assessee's back without granting cross-examination opportunities.
