Section 536 of the 2025 Act saves pending TP proceedings; framework preserved.
HISTORICAL CONTEXT
Section 10BB (Computer Programmes Production (Legacy)) is part of Chapter III - Incomes Not Included — 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 AMENDMENT TIMELINE
■ Income-tax Act 1961 — Original provision framework.
■ Finance Act 1989 — Major restructuring across many chapters.
■ Finance Act, 2026 (Act 4 of 2026) — no amendment to s. 10BB; section continues as a legacy / sunset provision with no new claims after the applicable cut-off AY.
▸ 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.
CBDT CIRCULARS — ECOSYSTEM
▸ CBDT Circular No. 14(XL-35) of 1955 dated 11 April 1955
Subject. Duty of officers to assist assessees in claiming and securing relief
Substance. Foundational circular directing that the AO should not exploit assessee ignorance to deny legitimate reliefs; officer is required to draw attention to refunds or reliefs to which the assessee is entitled. The circular has been judicially noted in several appellate decisions and remains operative for first-appellate practice.
Substance. Explained the FA 1987 / FA 1989 amendments unifying the previous year with the financial year preceding the AY, including transitional provisions for assessees with different accounting years. Useful in any controversy on the timing of accrual / chargeability for early post-1989 AYs.
▸ CBDT Circular No. 5 of 2014 dated 11 February 2014
Subject. Section 14A — dis-allowance even where no exempt income earned (since modulated)
Substance. Initially directed AOs to apply Rule 8D disallowance under section 14A even where no exempt income was earned in the year; subsequently modulated by Cheminvest (Del HC) and Maxopp (SC). FA 2022 amendment to section 14A re-asserted the position but remains under litigation.
▸ CBDT Circular No. 6 of 2019 dated 20 March 2019
Subject. Withdrawal of low-tax-effect appeals — monetary thresholds
Substance. Revised monetary thresholds for departmental appeals — ITAT (Rs 50L), HC (Rs 1 Cr), SC (Rs 2 Cr); subsequently further revised. Operates as a non-statutory limitation on the Revenue's appellate engagement, binding under section 119.
Substance. Procedural guidance for AOs handling transitional reassessment notices for AYs 2013-14 to 2017-18 affected by Ashish Agarwal and Rajeev Bansal. Sets out the form of section 148A inquiry, time-bar calculation under TOLA, and JAO/FAO jurisdiction in faceless cases.
WORKED EXAMPLES
Illustration — Illustration 1 — Standard 10BB application
Facts. Standard scenario invoking section 10BB (Computer Programmes Production (Legacy)).
Computation.
Operative provision applied per bare-Act framework.
Section 10BB invocation; companion-section coordination per Chapter III - Incomes Not Included.
(i) Masthead caption updated from “as amended by the Finance Act, 2025” to “as amended by the Finance Act, 2026”. (ii) Block 1 verbatim gazette text replaced entirely with the bare-Act text of s. 10BB extracted from the bare Act PDF (verified boundaries; marginal note included; off-by-one extraction defects from initial pass corrected); inline footnote markers in N[...] form preserved verbatim as they appear in the source. The prior Cowork Block 1 was an abbreviated / editorialised presentation. (iii) FA 2026 closing bullet added to the FINANCE ACT AMENDMENT TIMELINE recording that FA 2026 (Act 4 of 2026) makes no amendment to s. 10BB; bullet style matches the existing series. (iv) Year-anchored fact patterns in illustrations preserved as historical references — this is a sunset / legacy provision and the illustration fact patterns properly use historical AYs; no re-anchoring to PY 2025-26 / AY 2026-27 has been applied because the sunset bar makes current-year illustrations meaningless. (v) Standing-protocol audit: no “Act 7 of 2025” miscitation of the Income-tax Act, 2025 (Act 30 of 2025) found in this file; 2025-Act successor mapping in Block 2 generic, flagged for forward-pass enrichment. (vi) Source & verification notes cell not added in this revision — outside the scope of targeted XML edits per the Chapter III workflow; flagged for forward-pass restructuring. (vii) LEAN-TREATMENT NOTE — this section is a sunset / legacy provision; the file’s commentary depth has not been expanded in this revision. The full commentary architecture (statutory architecture map, judicial evolution, FA timeline) is retained for archival reference but should be re-examined in a forward pass for any residual claims that may continue to surface in transitional assessments under TOLA / s. 148A / Vivad se Vishwas frameworks. (viii) MAJOR CONTENT-CONTAMINATION FLAG — this Cowork /v3 file (in common with all five sunset-legacy files in Chapter III and the s. 10AA file) carries substantial Transfer Pricing content under content headers that should be specific to the section under treatment. The 18-row statutory architecture map row 01 calls s. 10BB “Chapter X-B (Transfer Pricing)” (s. 10BB sits in Chapter III, not Chapter X-B); rows 03 through 17 of that map describe TP concepts (international transaction / Associated Enterprises / ALP / FAR / TNMM / CUP / Form 3CEB / Master File [Form 3CEAA] / CbCR [Form 3CEAC] / TPO / DRP / APA / MAP / MLI / OECD BEPS / Schedule TP); the PRACTITIONER PLANNING NOTES (15 bullets) are entirely TP-themed; the LITIGATION DEFENCE block is largely TP-themed; the 15-step STEP-BY-STEP PROCEDURE is the TP workflow (AE identification, FAR, MAM selection, comparables, ALP computation, Form 3CEB, TPO proceedings under s. 92CA, DRP under s. 144C, APA / MAP); the 19-item PRACTITIONER CHECKLIST is the TP checklist. These blocks must be re-derived in a forward pass to reflect s. 10BB’s actual statutory framework (the export-undertaking / FTZ / EOU / hand-made-carpet / NE-region tax-holiday architecture, ten-consecutive-AY computation, Form 56F audit, sunset at AY 2012-13). These contaminated blocks have been retained intact in the file at the firm’s discretion — not silently deleted — so that the contamination is visible and can be excised or rewritten in a forward pass. The contamination is consistent across all five sunset-legacy files in Chapter III (10A, 10B, 10BA, 10BB, 10C) and the s. 10AA file; this appears to be a systematic Cowork production defect rather than a one-off.

14. Return / disclosure reporting
Form 3CEB (TP audit report); Master File (Form 3CEAA); CbCR (Form 3CEAC); Schedule TP in ITR.
15. Penalty exposure
Section 271AA / 271BA / 271G / 270A(9)(f) — TP-specific penalties.
16. Prosecution exposure
Section 276C — wilful evasion; rare in TP — civil-penalty framework dominates.
17. Cross-statute interplay
MLI Article 9 (treaty-level AE); OECD TP Guidelines 2022; BEPS Actions 8-10 / 13; FEMA / RBI.
18. Repeal & saving — 1961 → 2025
Section 536 of the 2025 Act saves pending TP proceedings; framework preserved.

(iv) Year-anchored fact patterns in illustrations preserved as historical references — this is a sunset / legacy provision and the illustration fact patterns properly use historical AYs; no re-anchoring to PY 2025-26 / AY 2026-27 has been applied because the sunset bar makes current-year illustrations meaningless. (v) Standing-protocol audit: no “Act 7 of 2025” miscitation of the Income-tax Act, 2025 (Act 30 of 2025) found in this file; 2025-Act successor mapping in Block 2 generic, flagged for forward-pass enrichment. (vi) Source & verification notes cell not added in this revision — outside the scope of targeted XML edits per the Chapter III workflow; flagged for forward-pass restructuring. (vii) LEAN-TREATMENT NOTE — this section is a sunset / legacy provision; the file’s commentary depth has not been expanded in this revision. The full commentary architecture (statutory architecture map, judicial evolution, FA timeline) is retained for archival reference but should be re-examined in a forward pass for any residual claims that may continue to surface in transitional assessments under TOLA / s. 148A / Vivad se Vishwas frameworks. (viii) MAJOR CONTENT-CONTAMINATION FLAG — this Cowork /v3 file (in common with all five sunset-legacy files in Chapter III and the s. 10AA file) carries substantial Transfer Pricing content under content headers that should be specific to the section under treatment. The 18-row statutory architecture map row 01 calls s. 10BB “Chapter X-B (Transfer Pricing)” (s. 10BB sits in Chapter III, not Chapter X-B); rows 03 through 17 of that map describe TP concepts (international transaction / Associated Enterprises / ALP / FAR / TNMM / CUP / Form 3CEB / Master File [Form 3CEAA] / CbCR [Form 3CEAC] / TPO / DRP / APA / MAP / MLI / OECD BEPS / Schedule TP); the PRACTITIONER PLANNING NOTES (15 bullets) are entirely TP-themed; the LITIGATION DEFENCE block is largely TP-themed; the 15-step STEP-BY-STEP PROCEDURE is the TP workflow (AE identification, FAR, MAM selection, comparables, ALP computation, Form 3CEB, TPO proceedings under s. 92CA, DRP under s. 144C, APA / MAP); the 19-item PRACTITIONER CHECKLIST is the TP checklist. These blocks must be re-derived in a forward pass to reflect s. 10BB’s actual statutory framework (the export-undertaking / FTZ / EOU / hand-made-carpet / NE-region tax-holiday architecture, ten-consecutive-AY computation, Form 56F audit, sunset at AY 2012-13). These contaminated blocks have been retained intact in the file at the firm’s discretion — not silently deleted — so that the contamination is visible and can be excised or rewritten in a forward pass. The contamination is consistent across all five sunset-legacy files in Chapter III (10A, 10B, 10BA, 10BB, 10C) and the s. 10AA file; this appears to be a systematic Cowork production defect rather than a one-off.
