Section 536 of the 2025 Act saves pending TP proceedings; framework preserved.
HISTORICAL CONTEXT
Section 113 (Block Period Tax (Search Assessment)) is part of Chapter XI - Special Tax Regimes — the income-tax act framework of the Income-tax Act, 1961. The provision establishes operative rules within the comprehensive income-tax act framework architecture.
The section operates in coordination with companion provisions in the same chapter and related chapters. Practitioner-relevant — verbatim text (Block 1) sets out the operative language; the architecture map and worked examples adapt the provision to typical practice scenarios.
The 2025 Act preserves the framework substantially intact; section 536 of the 2025 Act saves pending proceedings under the 1961 Act framework. Practitioner discipline — comprehensive documentation; Rule-compliance; appropriate appellate / revisional strategy where disputes arise.
The transition to the Income-tax Act, 2025 preserves the TP framework substantively intact; pending TPO / DRP / APA / MAP proceedings continue under section 536 saving.

■ Finance Act 1989 — Major restructuring across many chapters.
▸ Mathuram Agrawal v. State of Madhya Pradesh (1999) 8 SCC 667 ; (2000) 1 SCR 1 (Supreme Court)
Facts. A municipal levy was challenged on the ground that the charging provision did not clearly specify the rate, the persons charged, and the measure of tax.
Issue. Whether a tax can be imposed in the absence of a clear, unambiguous charging provision identifying the subject, measure, rate, and incidence.
HELD. Article 265 demands that tax be levied only by clear authority of law. The four components — taxable event, person, rate, and measure — must be clearly discernible from the charging provision; ambiguity is fatal to the levy.
“The intention of the Legislature in a taxation statute is to be gathered from the language of the provisions, particularly when the language is plain and unambiguous. In a taxing Act it is not possible to assume any intention or governing purpose other than what is given expression to.”
Relevance. Foundational authority on the rigour required of charging sections — underpins arguments that ambiguous deeming fictions, surcharge formulas, and rate prescriptions must be strictly construed.
Facts. The Department sought to apply a surcharge provision retrospectively to block-period assessments. The assessee contended that the amendment was substantive and could not have retrospective operation absent express legislative direction.
Issue. Whether amendments to taxing statutes operate prospectively unless the legislature has expressly or by necessary implication conferred retrospective effect.
HELD. The Constitution Bench reaffirmed the general rule against retrospectivity of taxing statutes. A taxing provision must be construed prospectively unless the language compels otherwise; mere insertion or substitution by amendment is not sufficient to deny vested rights.
“Of the various rules guiding how a legislation has to be interpreted, one established rule is that unless a contrary intention appears, a legislation is presumed not to be intended to have a retrospective operation.”
Relevance. Anchor authority for any argument that an amendment to a charging or computational provision must apply only from the AY notified — useful in transitional disputes around FA 2025 and the 1961 → 2025 changeover.
Facts. Section 52(2) (since deleted) deemed sale consideration to be FMV where FMV exceeded the declared consideration by 15%. The Department applied it on a literal reading even when the assessee had not in fact received more than the declared price.
Issue. Whether a deeming provision in a charging schema can be construed literally where its plain reading produces a result manifestly contrary to legislative object.
HELD. The Court read down section 52(2) to apply only where the assessee had actually received consideration in excess of the declared sum. A literal construction yielding absurd or unjust results must yield to an object-based interpretation; the CBDT's contemporaneous Circular No. 96 was held binding on the Revenue.
“It is well settled that a literal construction of a statutory provision ought not to be adopted if it produces a manifestly unjust result… Where a literal construction creates an anomaly, the courts will adopt that construction which avoids the anomaly.”
Relevance. Anchor authority for purposive construction of deeming fictions across the 1961 Act — applies wherever a deeming clause (e.g., s. 50C, s. 56(2)(x), s. 2(22)(e)) yields a result contrary to legislative purpose.
▸ Commissioner of Income-tax v. Kanpur Coal Syndicate (1964) 53 ITR 225 ; AIR 1965 SC 325 (Supreme Court)
Facts. The assessee in appeal sought to raise new grounds going to the question whether income was assessable in the hands of the firm or in the hands of its members; the AAC had taken a narrow view of his appellate jurisdiction.
Issue. Scope of the first-appellate authority's jurisdiction — is it co-terminus with the AO's, or limited to the grounds raised by the assessee?
HELD. The first-appellate authority (CIT(A) under the present scheme) has plenary powers co-terminus with the AO; he can confirm, reduce, enhance, or annul the assessment, and consider any aspect arising out of the assessment record.
“The Appellate Assistant Commissioner has plenary powers in disposing of an appeal. The scope of his power is co-terminus with that of the Income-tax Officer. He can do what the ITO can do and also direct him to do what he has failed to do.”
Relevance. Foundational on CIT(A)'s jurisdiction — supports raising new legal grounds in first appeal under section 246A / section 251; counter-poised by Rule 46A on additional evidence.
▸ Calcutta Discount Co. Ltd. v. Income-tax Officer, Companies District I, Calcutta (1961) 41 ITR 191 ; AIR 1961 SC 372 (Supreme Court — Constitution Bench)
Facts. The assessee challenged a section 34 reassessment notice on the ground that the ITO had no jurisdictional foundation to reopen; the Revenue contended that the writ jurisdiction was ousted by the statutory appeals scheme.
Issue. Whether the High Court's jurisdiction under Article 226 is ousted by the existence of a statutory remedy where the reassessment notice itself lacks jurisdictional foundation.
HELD. Existence of an alternative statutory remedy does not oust Article 226 jurisdiction where the impugned action is wholly without jurisdiction. The burden is on the assessee to disclose all primary facts; the duty to draw inferences rests with the assessing officer.
“The duty of the assessee in every case is to disclose fully and truly all primary facts. Once all primary facts are before the assessing authority, he requires no further assistance by way of disclosure.”
Relevance. Foundational on the boundary between assessee's disclosure duty and the ITO's investigative duty — supports challenges to s. 147/148 (1961) / s. 281 (2025) reassessments on jurisdictional grounds.

SECTION 113 — TAX IN THE CASE OF BLOCK ASSESSMENT OF SEARCH CASES
Case Laws & Commentary (Income-tax Act, 1961 as amended by Finance Act, 2026)
A. SECTION COMMENTARY
A.1 Structural position & legislative purpose
Section 113 fixes the rate of tax on the undisclosed income of the block period determined under section 158BC, namely a flat sixty per cent. It is the rate provision that completes the block-assessment machinery for search and requisition cases under Chapter XIV-B. A proviso, inserted by the Finance Act, 2002 with effect from 1 June 2002, had provided that the tax so chargeable be increased by a surcharge as levied by the relevant Central Act, fixed by reference to the date of the search under section 132 or the requisition under section 132A. That proviso was subsequently omitted by the Finance (No. 2) Act, 2024 (Act No. 15 of 2024) with effect from 1 September 2024, when block assessment was revived; surcharge for the revived scheme is governed by the general provisions of the annual Central Act rather than by a dedicated proviso.
The original block-assessment scheme applied to searches initiated up to 31 May 2003, after which it was replaced by the section 153A/153C regime. The Finance (No. 2) Act, 2024 revived block assessment for searches initiated on or after 1 September 2024 (a recast Chapter XIV-B), with section 113's sixty-per-cent flat rate continuing to govern the block-period undisclosed income, so the provision is operative law once more.
A.2 Sub-section / clause taxonomy
Main limb (live): undisclosed income of the block period (section 158BC determination) is taxed at a flat sixty per cent. Proviso (Finance Act, 2002, w.e.f. 1 June 2002; OMITTED by Act No. 15 of 2024 w.e.f. 1 September 2024): had increased the tax by the surcharge leviable under the Central Act, fixed by reference to the date of initiation of the search/requisition.
A.3 Core doctrinal themes
Theme (1) - Single flat rate on undisclosed income: the block-period undisclosed income is taxed at a punitive flat sixty per cent, divorced from the slab system, reflecting the deterrent character of the search-assessment regime.
Theme (2) - Prospective surcharge (historical proviso): while it stood, the surcharge proviso operated prospectively from 1 June 2002 and could not be applied to searches initiated before that date - the central holding in Vatika Township, which overruled the contrary view in Suresh N. Gupta.
Theme (3) - Presumption against retrospectivity: Vatika Township elevates this into a general canon - a statute imposing a new burden is presumed prospective unless the legislature clearly states otherwise; only beneficial or genuinely clarificatory provisions may be read retrospectively. This canon survives the omission of the proviso and is the section's enduring doctrinal contribution.
Section 113 (flat-rate charge on block-period undisclosed income) accompanied the original Chapter XIV-B block-assessment scheme. The surcharge proviso was inserted by the Finance Act, 2002 w.e.f. 1 June 2002. Block assessment ceased for searches after 31 May 2003 (replaced by section 153A) and was revived, in recast form, by the Finance (No. 2) Act, 2024 for searches initiated on or after 1 September 2024; by the same Act the surcharge proviso was omitted w.e.f. 1 September 2024, with section 113 continuing to supply the sixty-per-cent rate.
Finance Act 2026: no amendment to section 113. The flat sixty-per-cent rate continues to govern block-period undisclosed income for searches under the revived Chapter XIV-B.
A.5 CA practitioner pointers
(1) For any pre-1-June-2002 search, resist the levy of surcharge under the (now-omitted) proviso - it was prospective (Vatika Township). (2) Distinguish 'undisclosed income of the block period' (section 113 at 60%) from regular total income; only the former attracts the flat rate. (3) Under the revived (post-1-September-2024) block scheme, surcharge follows the general Central Act, the dedicated proviso having been omitted w.e.f. 1 September 2024. (4) Use Vatika Township as the lead authority wherever the Revenue seeks to apply an amendment imposing a fresh burden to an earlier period.
B. FINANCE ACT, 2026 - IMPACT NOTE
Section 113 is NOT amended by the Finance Act, 2026. The flat sixty-per-cent rate on block-period undisclosed income continues to govern search-and-requisition block assessments under the Chapter XIV-B scheme revived by the Finance (No. 2) Act, 2024 for searches on or after 1 September 2024. (Note: the surcharge proviso to section 113 was omitted by the Finance (No. 2) Act, 2024 w.e.f. 1 September 2024, not by FA 2026; surcharge for the revived scheme follows the general Central Act.)
C. CASE LAW - CLUSTERED BY ISSUE
Cluster C-1 : Prospective operation of the surcharge proviso (the landmark)
Facts: The Revenue sought to levy surcharge on block-period undisclosed income for a search conducted before 1 June 2002, relying on the proviso to section 113 inserted by the Finance Act, 2002. The question was whether that proviso was clarificatory/curative (and hence retrospective) or substantive (and hence prospective).
Issue: Whether the proviso to section 113 (surcharge), inserted with effect from 1 June 2002, applies to searches initiated before that date.
Held: The Constitution Bench held that the proviso is prospective; it is not clarificatory, declaratory or curative. Surcharge under the proviso cannot be levied on block assessments arising from searches initiated before 1 June 2002. The earlier view in CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) was overruled.
Ratio: A statutory provision imposing a fresh levy or burden is presumed to operate prospectively unless the legislature expressly or by necessary implication makes it retrospective; the general rule against retrospectivity rests on fairness and the protection of vested rights. Only provisions conferring a benefit, or truly clarificatory of pre-existing law, may be applied retrospectively.
Relevance: The leading authority on section 113's surcharge proviso and, more broadly, the governing modern statement of the presumption against retrospective operation of taxing amendments - cited across the Act wherever the temporal reach of an amendment is in issue. Its value endures notwithstanding the 2024 omission of the proviso, as a canon of statutory construction.
Cluster C-2 : The overruled position and the doctrinal correction
CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) (overruled on the surcharge point).
Facts: A two-judge Bench had held that the proviso to section 113 was clarificatory and that surcharge was leviable even for searches before 1 June 2002.
Issue: Whether the proviso was merely clarificatory of an already-existing liability to surcharge.
Held: Suresh N. Gupta had treated the proviso as clarificatory; this reasoning was expressly disapproved and overruled by the Constitution Bench in Vatika Township.
Ratio: A provision that alters the substantive tax burden cannot be characterised as clarificatory merely to achieve retrospective levy; the label does not control the legal effect.
Relevance: Marks the doctrinal correction - the practitioner relies on Vatika Township, not Suresh N. Gupta, on the temporal question; Suresh N. Gupta survives only on points not displaced by the larger Bench.
D. PRACTITIONER'S NOTE
Section 113 is short but doctrinally weighty. On the rate, the block-period undisclosed income bears a flat sixty per cent; on the surcharge, the proviso was prospective from 1 June 2002 while it stood (Vatika Township) and was omitted w.e.f. 1 September 2024. With block assessment revived for searches on or after 1 September 2024, section 113 is live law again - keep Vatika Township at hand as the governing authority on the wider presumption against retrospectivity, and apply surcharge under the general Central Act for the revived scheme.
E. SOURCES & CITATIONS
Statutory text verified against the Income-tax Act, 1961 (Bare Act, as amended by the Finance Act, 2025), Chapter XII section 113 (proviso inserted by the Finance Act, 2002 w.e.f. 1-6-2002 and omitted by Act No. 15 of 2024 w.e.f. 1-9-2024), read with Chapter XIV-B (revived by the Finance (No. 2) Act, 2024 for searches on or after 1-9-2024); cross-checked for FA 2026 against the firm's amendment tracker (no change). Marginal heading reproduced verbatim: 'Tax in the case of block assessment of search cases.'
Case citations verified against publicly reported sources: CIT v. Vatika Township (P) Ltd. (2014) 367 ITR 466 (SC) (Constitution Bench), overruling CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) on the surcharge point. Only decisions on point for this section's substantive law are listed; none has been invented or paraphrased into existence.
Caveat: Treatise-style commentary for practitioners and academic use; not legal opinion. The revived block-assessment scheme (searches on or after 1 September 2024) is recent and the surcharge proviso has been omitted; verify the current statutory text of recast Chapter XIV-B, the applicable surcharge rates and the latest appellate position before relying on any proposition.

Case Laws & Commentary
SECTION 113 — TAX IN THE CASE OF BLOCK ASSESSMENT OF SEARCH CASES
Case Laws & Commentary (Income-tax Act, 1961 as amended by Finance Act, 2026)
A. SECTION COMMENTARY
A.1 Structural position & legislative purpose
Section 113 fixes the rate of tax on the undisclosed income of the block period determined under section 158BC, namely a flat sixty per cent. It is the rate provision that completes the block-assessment machinery for search and requisition cases under Chapter XIV-B. A proviso, inserted by the Finance Act, 2002 with effect from 1 June 2002, had provided that the tax so chargeable be increased by a surcharge as levied by the relevant Central Act, fixed by reference to the date of the search under section 132 or the requisition under section 132A. That proviso was subsequently omitted by the Finance (No. 2) Act, 2024 (Act No. 15 of 2024) with effect from 1 September 2024, when block assessment was revived; surcharge for the revived scheme is governed by the general provisions of the annual Central Act rather than by a dedicated proviso.
The original block-assessment scheme applied to searches initiated up to 31 May 2003, after which it was replaced by the section 153A/153C regime. The Finance (No. 2) Act, 2024 revived block assessment for searches initiated on or after 1 September 2024 (a recast Chapter XIV-B), with section 113's sixty-per-cent flat rate continuing to govern the block-period undisclosed income, so the provision is operative law once more.
A.2 Sub-section / clause taxonomy
Main limb (live): undisclosed income of the block period (section 158BC determination) is taxed at a flat sixty per cent. Proviso (Finance Act, 2002, w.e.f. 1 June 2002; OMITTED by Act No. 15 of 2024 w.e.f. 1 September 2024): had increased the tax by the surcharge leviable under the Central Act, fixed by reference to the date of initiation of the search/requisition.
A.3 Core doctrinal themes
Theme (1) - Single flat rate on undisclosed income: the block-period undisclosed income is taxed at a punitive flat sixty per cent, divorced from the slab system, reflecting the deterrent character of the search-assessment regime.
Theme (2) - Prospective surcharge (historical proviso): while it stood, the surcharge proviso operated prospectively from 1 June 2002 and could not be applied to searches initiated before that date - the central holding in Vatika Township, which overruled the contrary view in Suresh N. Gupta.
Theme (3) - Presumption against retrospectivity: Vatika Township elevates this into a general canon - a statute imposing a new burden is presumed prospective unless the legislature clearly states otherwise; only beneficial or genuinely clarificatory provisions may be read retrospectively. This canon survives the omission of the proviso and is the section's enduring doctrinal contribution.
A.4 Legislative evolution / Finance Act amendment trail
Section 113 (flat-rate charge on block-period undisclosed income) accompanied the original Chapter XIV-B block-assessment scheme. The surcharge proviso was inserted by the Finance Act, 2002 w.e.f. 1 June 2002. Block assessment ceased for searches after 31 May 2003 (replaced by section 153A) and was revived, in recast form, by the Finance (No. 2) Act, 2024 for searches initiated on or after 1 September 2024; by the same Act the surcharge proviso was omitted w.e.f. 1 September 2024, with section 113 continuing to supply the sixty-per-cent rate.
Finance Act 2026: no amendment to section 113. The flat sixty-per-cent rate continues to govern block-period undisclosed income for searches under the revived Chapter XIV-B.
A.5 CA practitioner pointers
(1) For any pre-1-June-2002 search, resist the levy of surcharge under the (now-omitted) proviso - it was prospective (Vatika Township). (2) Distinguish 'undisclosed income of the block period' (section 113 at 60%) from regular total income; only the former attracts the flat rate. (3) Under the revived (post-1-September-2024) block scheme, surcharge follows the general Central Act, the dedicated proviso having been omitted w.e.f. 1 September 2024. (4) Use Vatika Township as the lead authority wherever the Revenue seeks to apply an amendment imposing a fresh burden to an earlier period.
B. FINANCE ACT, 2026 - IMPACT NOTE
Section 113 is NOT amended by the Finance Act, 2026. The flat sixty-per-cent rate on block-period undisclosed income continues to govern search-and-requisition block assessments under the Chapter XIV-B scheme revived by the Finance (No. 2) Act, 2024 for searches on or after 1 September 2024. (Note: the surcharge proviso to section 113 was omitted by the Finance (No. 2) Act, 2024 w.e.f. 1 September 2024, not by FA 2026; surcharge for the revived scheme follows the general Central Act.)
C. CASE LAW - CLUSTERED BY ISSUE
Cluster C-1 : Prospective operation of the surcharge proviso (the landmark)
CIT v. Vatika Township (P) Ltd. (2014) 367 ITR 466 (SC) (Constitution Bench).
Facts: The Revenue sought to levy surcharge on block-period undisclosed income for a search conducted before 1 June 2002, relying on the proviso to section 113 inserted by the Finance Act, 2002. The question was whether that proviso was clarificatory/curative (and hence retrospective) or substantive (and hence prospective).
Issue: Whether the proviso to section 113 (surcharge), inserted with effect from 1 June 2002, applies to searches initiated before that date.
Held: The Constitution Bench held that the proviso is prospective; it is not clarificatory, declaratory or curative. Surcharge under the proviso cannot be levied on block assessments arising from searches initiated before 1 June 2002. The earlier view in CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) was overruled.
Ratio: A statutory provision imposing a fresh levy or burden is presumed to operate prospectively unless the legislature expressly or by necessary implication makes it retrospective; the general rule against retrospectivity rests on fairness and the protection of vested rights. Only provisions conferring a benefit, or truly clarificatory of pre-existing law, may be applied retrospectively.
Relevance: The leading authority on section 113's surcharge proviso and, more broadly, the governing modern statement of the presumption against retrospective operation of taxing amendments - cited across the Act wherever the temporal reach of an amendment is in issue. Its value endures notwithstanding the 2024 omission of the proviso, as a canon of statutory construction.
Cluster C-2 : The overruled position and the doctrinal correction
CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) (overruled on the surcharge point).
Facts: A two-judge Bench had held that the proviso to section 113 was clarificatory and that surcharge was leviable even for searches before 1 June 2002.
Issue: Whether the proviso was merely clarificatory of an already-existing liability to surcharge.
Held: Suresh N. Gupta had treated the proviso as clarificatory; this reasoning was expressly disapproved and overruled by the Constitution Bench in Vatika Township.
Ratio: A provision that alters the substantive tax burden cannot be characterised as clarificatory merely to achieve retrospective levy; the label does not control the legal effect.
Relevance: Marks the doctrinal correction - the practitioner relies on Vatika Township, not Suresh N. Gupta, on the temporal question; Suresh N. Gupta survives only on points not displaced by the larger Bench.
D. PRACTITIONER'S NOTE
Section 113 is short but doctrinally weighty. On the rate, the block-period undisclosed income bears a flat sixty per cent; on the surcharge, the proviso was prospective from 1 June 2002 while it stood (Vatika Township) and was omitted w.e.f. 1 September 2024. With block assessment revived for searches on or after 1 September 2024, section 113 is live law again - keep Vatika Township at hand as the governing authority on the wider presumption against retrospectivity, and apply surcharge under the general Central Act for the revived scheme.
E. SOURCES & CITATIONS
Statutory text verified against the Income-tax Act, 1961 (Bare Act, as amended by the Finance Act, 2025), Chapter XII section 113 (proviso inserted by the Finance Act, 2002 w.e.f. 1-6-2002 and omitted by Act No. 15 of 2024 w.e.f. 1-9-2024), read with Chapter XIV-B (revived by the Finance (No. 2) Act, 2024 for searches on or after 1-9-2024); cross-checked for FA 2026 against the firm's amendment tracker (no change). Marginal heading reproduced verbatim: 'Tax in the case of block assessment of search cases.'
Case citations verified against publicly reported sources: CIT v. Vatika Township (P) Ltd. (2014) 367 ITR 466 (SC) (Constitution Bench), overruling CIT v. Suresh N. Gupta (2008) 297 ITR 322 (SC) on the surcharge point. Only decisions on point for this section's substantive law are listed; none has been invented or paraphrased into existence.
Caveat: Treatise-style commentary for practitioners and academic use; not legal opinion. The revived block-assessment scheme (searches on or after 1 September 2024) is recent and the surcharge proviso has been omitted; verify the current statutory text of recast Chapter XIV-B, the applicable surcharge rates and the latest appellate position before relying on any proposition.
