Technical Grounds for a Favourable Income Tax Appeal

Assessing Officer Defaults and Procedural Lapses

A Practitioner's Reference — 28 Grounds With Supporting Case Law and Drafting Tips

Covers the Income-tax Act, 2025 and the corresponding, still-citable jurisprudence under the Income-tax Act, 1961

This document collects the technical and procedural grounds most frequently used by tax professionals to secure a favourable outcome in an income tax appeal — grounds that arise from defaults, lapses or errors on the part of the Assessing Officer (or the sanctioning/approving authority) during the assessment process, as distinct from arguing the substantive merits of an addition. In many cases, a well-pleaded technical ground disposes of the matter without the appellate authority ever needing to examine the merits at all.

Grounds are organised into eight categories: jurisdictional defaults, limitation defaults, sanction and approval defaults, natural justice and procedural fairness defaults, reassessment-specific defaults, evidentiary and merits-based technical defaults, search and block assessment defaults, and order/computation-level defaults. Each ground includes the underlying principle, the leading case law supporting it, and a practical note on how to raise it effectively in the grounds of appeal.

Because the Income-tax Act, 2025 is a recently commenced statute, the case law cited below was developed under the corresponding provisions of the Income-tax Act, 1961. As explained in the companion series on assessment and reassessment under the new Act, Section 536(2)(j) of the 2025 Act preserves the continued relevance of this jurisprudence, and Article 141 of the Constitution binds all courts and tribunals to Supreme Court precedent, so long as the statutory language and conditions remain substantively comparable.

Every assessment, reassessment or notice must originate from the Assessing Officer who validly holds jurisdiction over the assessee — determined by territorial area, the class of persons, or the specific case assigned under the department's jurisdiction orders. Where a notice under Section 270(10), 271 or 280 of the Income-tax Act, 2025 (or the corresponding 1961 Act provisions for transition-period matters) is issued by an officer who does not hold this jurisdiction — for instance, because the assessee's PAN was transferred to a different circle, or the case was never validly transferred under the transfer-of-cases provisions — the entire proceeding is vulnerable to challenge as being without jurisdiction.

This ground is particularly relevant where a search-related case is transferred to a Central Circle, or where an international taxation matter is assigned to a domestic circle in error, since jurisdiction in these categories follows specific, published orders rather than the assessee's registered address alone.

Case law: Pr. CIT v. I-Ven Interactive Ltd. (2019) 418 ITR 662 (SC) — held that where an assessee raises an objection to jurisdiction, the burden shifts to the revenue to demonstrate compliance with the statutory procedure for assumption of jurisdiction, including in cases of change of address or transfer of the case file; failure to demonstrate this can be fatal to the assessment.

Where a company has amalgamated, merged, converted its form, or otherwise ceased to exist as a distinct legal person before the date an assessment order is passed — and the department has been informed of this fact — an assessment order issued in the name of the extinguished entity is a substantive jurisdictional defect, not a mere clerical error. The same principle applies where an individual has died and the return or assessment continues to be framed in the deceased's name without bringing the legal representative on record in the manner the Act requires.

This is one of the most consistently successful technical grounds in Indian tax litigation, precisely because courts have repeatedly held that an assessment on a 'non-person' cannot later be cured by treating the defect as a mere procedural irregularity — the department must substitute the successor entity or legal representative on record before proceeding, and its failure to do so despite being informed cannot later be excused.

Case law: PCIT v. Maruti Suzuki India Ltd. (2019) 416 ITR 613 (SC) — held that an assessment order framed in the name of an amalgamating company that had ceased to exist under an approved scheme of amalgamation is void ab initio, and that mere participation by the amalgamated company in the proceedings does not operate as an estoppel against this settled position of law, since there can be no estoppel against a statute. The Court did, however, clarify in the later ruling in PCIT v. Mahagun Realtors (P) Ltd. (2022) that this outcome is fact-sensitive — where both entities are named in the order and the successor has actively and substantively participated throughout without raising the objection at the earliest opportunity, the defect may in some circumstances be treated as curable; the ground is strongest where the objection is raised promptly and the order names only the extinguished entity.

CBDT Circular No. 19/2019 mandates that every communication issued by an income tax authority — including assessment orders, notices, letters and summons — must bear a computer-generated Document Identification Number, with only a narrow set of specified exceptional circumstances permitting manual issuance, subject to mandatory regularisation within a prescribed window. This requirement was designed to create a verifiable audit trail and curb the issuance of backdated or unauthenticated communications.

An order or notice issued without a DIN, and without falling within one of the circular's specific exceptions, is treated by the department's own binding administrative instruction as invalid and deemed never to have been issued at all — a significantly stronger consequence than an ordinary curable procedural defect.

Case law: CIT (International Taxation) v. Brandix Mauritius Holdings Ltd. (2023) 456 ITR 34 (Delhi HC) — affirmed the Tribunal's quashing of a final assessment order that did not bear a DIN, holding that the statutory defect could not be cured through Section 292B (which saves orders from invalidity for mere technical defects, mistakes or omissions), because the absence of DIN was not a mere clerical omission but went to the very validity of the communication under the CBDT's own binding circular.

A notice reopening an assessment must be issued within the outer time limits the Act prescribes — four years and three months (extendable to six years and three months for escapement of ₹50 lakh or more) from the end of the relevant tax year under Section 282 of the 2025 Act, or the corresponding periods under Section 149 of the 1961 Act for earlier years. A notice issued after this window has closed is void for want of jurisdiction, regardless of how strong the department's case may be on the underlying facts.

Limitation disputes frequently turn on two subtleties: the correct computation of exclusion periods (time covered by a stay, or the period taken to respond to a show-cause notice), and whether the extended six-year window has been validly invoked by demonstrating the requisite quantum and category of escaped income, rather than merely asserting it.

Case law: Union of India v. Rajeev Bansal (2024) (Supreme Court, Larger Bench) — worked through, in considerable arithmetical detail, how pandemic-period extensions and exclusion periods interact with the ordinary limitation framework, confirming that the department must strictly justify every day of extension it claims, and that a notice found to be issued even a single day beyond the properly computed limitation date is liable to be quashed.

Separately from the deadline for issuing the initiating notice, the Act prescribes an outer deadline for completing the resulting assessment or reassessment — generally one year from the end of the financial year in which the reassessment notice was served, under Section 286 of the 2025 Act (or the corresponding Sections 153/153B of the 1961 Act for transition-period matters), subject to specified extensions for matters such as transfer pricing references, special audits, or court-stayed proceedings.

An order passed after this deadline has expired is void, and this defect is entirely independent of, and can be raised in addition to, any challenge to the validity or timeliness of the original notice.

Case law: CIT v. Bhagwan Devi Saraogi (1979) 118 ITR 906 (Cal HC), read with the broader line of authority under Sections 153/286 — represents the settled principle that limitation periods for completion of assessment are mandatory and not merely directory, so that an order passed even marginally beyond the prescribed deadline cannot be saved by demonstrating that the delay caused no prejudice to the assessee.

No reassessment notice can be issued without the prior approval of a specified sanctioning authority under Section 284 of the 2025 Act (or Section 151 of the 1961 Act for earlier years). This sanction is not intended as a rubber stamp — the sanctioning authority is expected to genuinely examine the material placed before it and record, even briefly, that independent satisfaction has been applied, rather than simply endorsing the proposing officer's recommendation.

Where the approval on record consists of a bare 'approved,' 'yes,' or similar one-word endorsement with no indication that the sanctioning authority engaged with the underlying material, this is treated as no sanction at all in the eyes of the law, and the resulting notice — and everything that follows from it — is liable to be quashed.

Case law: Chhugamal Rajpal v. S.P. Chaliha (1971) 79 ITR 603 (SC) — remains the classic illustration: the sanctioning authority had simply written 'yes' on the proposal placed before it, and the Supreme Court held this did not satisfy the statutory sanction requirement, since there was no evidence of independent application of mind to the material relied upon for reopening.

The seniority of the sanctioning authority required generally increases with the length of time elapsed since the end of the relevant tax year — a more senior authority's approval is required as the case moves from the standard limitation window into the extended, high-value-escapement window. Where the department obtains sanction from an authority of insufficient seniority for the time band actually applicable to the notice, the sanction does not meet the statutory requirement even if it is otherwise a considered, reasoned approval.

Case law: Om Prakash Bhatia v. ITO / general line of authority under Section 151 (various High Court rulings) — consistently hold that obtaining sanction from the wrong authority is not a mere irregularity curable under Section 292B, because the identity of the sanctioning authority is itself a jurisdictional pre-condition prescribed by the statute, not a matter of form.

Where a draft order under the faceless assessment scheme (Section 273 of the 2025 Act, corresponding to Section 144B) proposes a variation prejudicial to the assessee, the assessee is entitled to request a personal hearing, typically through video conferencing. Courts have consistently held that once such a hearing is specifically requested, the department's discretion narrows into a practical obligation to grant it, particularly in factually complex or high-value matters.

Case law: Sanjay Aggarwal v. National Faceless Assessment Centre (2021) 127 taxmann.com 637 (Delhi HC) — held that the discretionary word 'may' in the hearing-request provision does not absolve the department of its obligation to consider and grant a requested hearing, and that denial of a specifically requested hearing violates both the statutory scheme and natural justice.

Where the Assessing Officer relies on information, statements or documents gathered from a third party — a bank, another taxpayer, an information-sharing arrangement, or a survey at a different premises — without disclosing that material to the assessee and affording a genuine opportunity to rebut it, any addition based on that undisclosed material is legally unsustainable.

Case law: Kishinchand Chellaram v. CIT (1980) 125 ITR 713 (SC) — held that an addition based on a bank's letter obtained behind the assessee's back, without furnishing a copy to the assessee and allowing rebuttal, could not be sustained; the principle applies squarely to any material — AIS/SFT data, third-party statements, or search material from another premises — relied upon without disclosure.

Where an addition rests substantially on a statement recorded from a third party — a supplier, an entry-provider, a co-accused in a search, or any other witness — and the assessee specifically requests an opportunity to cross-examine that witness, refusal to provide this opportunity while still relying on the statement to sustain the addition is a serious procedural flaw that goes to the root of the order's validity, not a mere irregularity.

Case law: Andaman Timber Industries v. Commissioner of Central Excise (2015) 281 CTR 241 (SC) — held, in terms that have since been widely applied in income tax proceedings as well, that not allowing an assessee to cross-examine witnesses whose statements are made the basis of an adverse order is a serious flaw that renders the order a nullity, since it amounts to a violation of the principles of natural justice.

While the Act does not always prescribe a fixed minimum response period for every query, courts have held that the time actually allowed must be reasonable in light of the complexity of the issue and the volume of material the assessee is asked to produce or explain. A response window so short that meaningful compliance is practically impossible defeats the purpose of the opportunity being granted in the first place.

Case law: Shree Ganesh Intermediary Private Limited v. National Faceless Assessment Centre (Gujarat HC) — quashed a faceless assessment order where the taxpayer was given only one day to respond to notices, holding that such an inadequate window itself amounts to a violation of natural justice and procedural fairness, independent of any separate personal-hearing request.

Where the final assessment order is passed on the very same day the assessee's detailed reply to a show-cause notice is filed — or otherwise so soon afterward that meaningful review is implausible — this timing itself becomes evidence that the reply was not genuinely considered, rather than a mere coincidence of dates.

Case law: A 2026 Calcutta High Court ruling on the same-day-order practice (₹87 crore faceless assessment matter) — held that passing the final order on the very day the reply is filed constitutes a 'ritualistic formality' rather than genuine consideration, quashing the order and the consequential demand and penalty notices, and reaffirming that this defect cannot be cured merely because an appellate remedy exists.

In cases involving specified transfer pricing adjustments or eligible foreign companies/international matters, the Act mandates that the Assessing Officer first pass a draft assessment order, communicate it to the assessee, and allow the assessee to either accept it or file objections before the Dispute Resolution Panel, before any final order proposing a variation can be passed. Bypassing this draft-order stage and proceeding directly to a final order is a jurisdictional defect, not a technical irregularity.

Case law: Zuari Cement Ltd. v. ACIT (Andhra Pradesh HC, 2013; Revenue's SLP dismissed by the Supreme Court, 27 September 2013) — categorically held that failure to pass a draft assessment order under the mandatory provision renders the final assessment order without jurisdiction, null and void and unenforceable — a ruling since followed by the Delhi, Bombay and Madras High Courts, and one the Supreme Court itself declined to disturb.

Reassessment is a power to bring genuinely escaped income to tax on the basis of new information — it is not a power to review or re-appreciate material that was already before the Assessing Officer and available for consideration during the original assessment. Where the reopening is, in substance, an attempt to take a second, different view of facts and figures already disclosed and examined earlier, it is barred as a change of opinion.

Case law: CIT v. Kelvinator of India Ltd. (2010) 320 ITR 561 (SC) (Full Bench) — authoritatively settled that 'reason to believe' income has escaped assessment cannot be equated with a mere change of mind on material already considered, and that permitting otherwise would effectively convert the reassessment power into an unrestricted power of review, which the statute does not confer.

Where the reopening is triggered purely by information or a report received from another authority (an investigation wing, another jurisdictional officer, or a different department) and the Assessing Officer merely reproduces that information verbatim as the basis for reopening — without recording any independent examination of how it applies to the specific assessee's facts — the reopening reflects 'borrowed satisfaction' rather than the Assessing Officer's own, and is legally infirm.

Case law: PCIT v. RMG Polyvinyl (I) Ltd. (2017) 396 ITR 5 (Delhi HC) — held that reopening based mechanically on information from the investigation wing, without the Assessing Officer applying independent mind to examine whether and how that information actually implicated the specific assessee, could not sustain a valid reassessment.

The information relied upon to reopen an assessment must have a rational, demonstrable connection with the specific assessee and the specific year in question — a generic reference to 'accommodation entries in the market' or similarly broad, unspecific language, without identifying the particular transaction, amount, or counterparty relevant to the assessee, does not meet the statutory threshold.

Case law: Pr. CIT v. Meenakshi Overseas (P) Ltd. (2017) 395 ITR 677 (Delhi HC) — quashed a reassessment where the reasons recorded merely referred in general terms to information about accommodation entries without specifying which entry, from which entity, and for what amount was attributable to the assessee, holding that such vague reasons do not disclose the requisite live link to the assessee's own escapement of income.

Where a reassessment is initiated on a specific, identified ground of escaped income, and during the course of the proceeding the Assessing Officer concludes that the originally identified escapement did not in fact occur, but proceeds instead to make additions on an entirely different, unrelated issue that came to light only during the reassessment, this raises a substantial question about whether the reassessment can validly extend to that unrelated issue at all.

Case law: CIT v. Jet Airways (India) Ltd. (2011) 331 ITR 236 (Bombay HC) — held that where the Assessing Officer, after issuing a reopening notice, does not ultimately assess the income for which the notice was originally issued, it is not open to him to independently assess some other income that has escaped assessment and which comes to his notice subsequently in the course of proceedings, unless the statutory conditions for doing so are separately satisfied.

On receiving a reassessment notice, an assessee is entitled to seek the reasons for reopening, file objections to those reasons, and have those objections disposed of by the Assessing Officer through a separate, reasoned order before the reassessment itself proceeds any further. Completing the reassessment without following this sequence — or disposing of the objections only as part of the final order itself, leaving no real opportunity to challenge the rejection before the assessment is finalised — is a procedural default.

Case law: GKN Driveshafts (India) Ltd. v. ITO (2003) 259 ITR 19 (SC) — laid down this exact sequence as mandatory: file the return, seek reasons, file objections, and require the Assessing Officer to dispose of the objections by a speaking order before proceeding further; a reassessment completed without following this sequence is procedurally infirm.

An assessment must be founded on evidence and rational inference, not on the Assessing Officer's subjective suspicion or an inference drawn without any supporting material. Where an addition rests essentially on the officer's own doubt about the plausibility of a transaction, without independent evidence contradicting the assessee's explanation and supporting documentation, the addition is vulnerable on the merits, independent of any procedural defect.

Case law: Dhakeshwari Cotton Mills Ltd. v. CIT (1954) 26 ITR 775 (SC) — and its companion authority Umacharan Shaw & Bros v. CIT (1959) 37 ITR 271 (SC) together establish that while the Assessing Officer is not bound by strict rules of evidence, an assessment cannot be based on pure suspicion, surmise and conjecture unsupported by any material, and that the assessee is entitled to know the material being used against him so that it can be rebutted.

Where an addition rests on a statement recorded during survey, search, or a summons proceeding, and that statement is subsequently retracted by the person who made it — with a credible explanation for the retraction, such as duress or lack of access to records at the time — the statement alone, without independent corroborating material, is generally insufficient to sustain an addition.

Case law: CIT v. S. Khader Khan Son (2013) 352 ITR 480 (SC) — held that a statement recorded during a survey under Section 133A does not by itself have the same evidentiary value as a statement recorded on oath during a search, and cannot alone be made the sole basis for an addition without independent corroborating evidence, particularly once retracted.

Where the department has, over a period of years, consistently accepted a particular position, method of accounting, or characterisation of income or expenditure on materially identical facts, a sudden departure from that consistent position in a later year — without any change in facts or law — is open to challenge on the principle of consistency, particularly where the fundamental facts have not changed.

Case law: Radhasoami Satsang v. CIT (1992) 193 ITR 321 (SC) — held that where a fundamental aspect permeating through different assessment years has been found as a fact one way or the other, and parties have proceeded on that basis, it is not appropriate to allow the position to be changed in a subsequent year in the absence of any material change in circumstances.

Before an Assessing Officer can resort to a best judgment assessment on the ground that the books of account are unreliable or incomplete, the books must first be properly examined and specifically rejected, with defects identified — a general, unparticularised statement that the accounts are 'not reliable' or 'not verifiable' does not meet this threshold.

Case law: CIT v. Kishan Chand Chellaram (and the broader Velukutty/Laxminarayan Badridas line of authority) — read together, these authorities confirm that a best judgment assessment must be grounded in a fair and honest estimate connected to specific, identified deficiencies in the material available, not a bare assertion of unreliability.

Where the same item of income is added to the assessee's total income more than once — whether across different heads of income in the same year, in both the hands of the assessee and a related entity for the same underlying transaction, or across two different years for the same receipt — this offends the basic principle that the same income cannot be taxed twice in the hands of the same taxpayer.

Case law: Laxmipat Singhania v. CIT (1969) 72 ITR 291 (SC) — held that the same income cannot be taxed twice, either directly or indirectly, in the hands of the same assessee, reinforcing a foundational principle that appellate authorities apply readily once a genuine duplication is demonstrated on the facts.

For any year within the block period whose assessment had already attained finality before the date of search, additions in the resulting block assessment can be made only where they are traceable to incriminating material actually found during that search — the department cannot use the occasion of a search to reopen and re-examine unrelated issues in a year that was not otherwise pending.

Case law: PCIT v. Abhisar Buildwell (P) Ltd. (2023) 454 ITR 212 (SC) — definitively settled that in respect of completed or unabated assessments, no addition can be made in a search assessment absent incriminating material found during the search itself, substantially approving the earlier Delhi High Court ruling in CIT v. Kabul Chawla (2016) 380 ITR 573.

Search-related assessments generally require the approval of a senior authority before the assessment order is finalised, analogous to the sanction requirement for reassessment. Where this approval is granted in bulk, across numerous unrelated assessees, without any indication of case-specific examination — often evidenced by identical, templated approval language across dozens of cases approved on the same date — the approval fails to meet the standard of genuine application of mind the law requires.

Case law: PCIT v. Anuj Bansal / the broader line of authority on Section 153D-type approvals (various High Court and Tribunal rulings) — have quashed search assessments where the approving authority granted sanction for numerous cases on the same day with identical, formulaic language, holding this to be indicative of mechanical approval rather than the meaningful application of mind the statute contemplates.

Where tax has genuinely been deducted or collected at source and is duly reflected against the assessee's PAN in Form 26AS or the corresponding statement, but the assessment order nonetheless fails to grant credit for that tax — whether due to a mismatch in the assessment year of credit, a processing error, or an oversight — this creates an inflated demand that has nothing to do with the substantive correctness of the income assessed, and is a purely computational default.

Rectification is meant to correct only clear, self-evident errors — not to allow the department to revisit a debatable point of law or a matter requiring fresh investigation under the guise of correcting an apparent mistake. Where a rectification order under Section 287 increases the assessee's liability by re-deciding an issue on which two views were reasonably possible, this exceeds the scope the provision permits.

Case law: T.S. Balaram, ITO v. Volkart Brothers (1971) 82 ITR 50 (SC) — held that a mistake apparent from the record must be an obvious and patent mistake, not something established only by a long-drawn process of reasoning on a point where two opinions are reasonably possible; a debatable point of law can never be treated as a mistake apparent from the record.

Where an appellate authority, the ITAT, or the Dispute Resolution Panel has issued specific, binding directions on an issue — whether allowing relief, directing a particular method of computation, or remanding a specific point for fresh consideration — the Assessing Officer is bound to give full effect to those directions. An order that ignores, only partially implements, or reopens a point that was conclusively decided in the assessee's favour by a binding direction is itself defective.
