Section 149 is the operative time-bar provision. Post-FA 2021 framework: (a) 3-year standard time-bar — applies in ALL cases; (b) 10-year extended time-bar — applies WHERE escaped income ≥ Rs 50 L AND represented in asset / transaction / event / entries (s. 149(3) defines asset broadly to include immovable / shares / loans / deposits).
Pre-FA 2021 framework was different — 4-year / 6-year / 16-year time-bars based on various conditions. FA 2021 simplified to 3-year / 10-year. Transitional issues — AY 2013-14 to AY 2017-18 — resolved by Rajeev Bansal (SC 2024) under TOLA framework.
TOLA (Taxation and Other Laws (Relaxation) Act, 2020) — COVID-period limitation extension — operative until 31-March-2021. Combined with FA 2021 amendments — created complex transitional matrix resolved by Rajeev Bansal. Practitioner discipline — AY-wise time-bar computation + income threshold + TOLA extension.
The transition to the Income-tax Act, 2025 preserves the procedural framework.

▸ Union of India v. Rajeev Bansal (2024) 469 ITR 46 ; 2024 SCC OnLine SC 2693 (Supreme Court — 3-Judge Bench (operative limb of Constitution Bench reference))
Facts. Hundreds of reassessment cases following Ashish Agarwal were challenged on time-bar grounds; the Department contended that TOLA (the COVID-period limitation extension) applied to extend the time for issuing notices.
Issue. Whether TOLA extended the limitation under the new section 148A scheme; operative consequences of Ashish Agarwal on reassessment validity.
HELD. The Court held TOLA applies to extend limitation for the reassessment regime; clarified the operative time-bar matrix for AYs 2013-14 onwards; set out detailed directions on JAO/FAO jurisdiction, satisfaction notes, and the right of the assessee to object.
“In the absence of any decision to the contrary, the Revenue's reliance on TOLA was upheld… The directions in Ashish Agarwal apply pan-India and bind all jurisdictional Assessing Officers.”
Relevance. Most recent and comprehensive Supreme Court authority on reassessment under the 1961 Act post-FA 2021 — defines the operative landscape for ongoing section 147/148 matters.
▸ Union of India v. Ashish Agarwal (2022) 444 ITR 1 ; 2022 SCC OnLine SC 543 (Supreme Court — 3-Judge Bench)
Facts. Following the FA 2021 overhaul of the reassessment scheme, the Department issued notices under the pre-amendment section 148 framework in April–June 2021; the High Courts had quashed those notices for non-compliance with the new section 148A.
Issue. Validity of transitional reassessment notices issued under the pre-1-April-2021 framework after the new section 148A scheme came into force.
HELD. Exercising Article 142 jurisdiction, the Court deemed all such transitional notices as having been issued under the new section 148A scheme. The Department was directed to supply material relied upon to the assessees, who were then to be heard before any reassessment was reopened.
“The Revenue cannot be made remediless… In exercise of our powers under Article 142, we hold that the impugned section 148 notices… shall be deemed to have been issued under section 148A of the IT Act as substituted by the Finance Act, 2021.”
Relevance. Critical authority on transitional reassessment validity; followed and elaborated in Rajeev Bansal (2024) on time-limits, satisfaction, and JAO/FAO jurisdiction.
Facts. The assessee received a section 148 notice but was not furnished the reasons recorded by the ITO. The High Court declined to interfere and directed the assessee to pursue the assessment.
Issue. Procedure for challenge to a section 148 reassessment notice — must the assessee be furnished reasons recorded, and may objections be raised before participating in the assessment.
HELD. On receipt of notice under section 148, the assessee may file a return and seek reasons recorded by the ITO. The ITO is bound to furnish the reasons within a reasonable time; the assessee may then file objections, which the ITO must dispose of by a speaking order before proceeding with the assessment.
“We clarify that when a notice under section 148 is issued, the proper course of action for the noticee is to file return and if he so desires, to seek reasons for issuing the notices. The Assessing Officer is bound to furnish reasons within a reasonable time.”
Relevance. Operative authority on the reassessment procedure under sections 147/148 — still good law for the procedural framework even after the FA 2021 overhaul and Ashish Agarwal.
▸ 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.
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.
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 3-year time-bar
Facts. A's AY 2022-23; notice considered 2025-26.
Computation.
End of AY 2022-23 = 31-3-2023.
3 years from end = 31-3-2026.
Notice by 31-3-2026 = within time-bar.
Post 31-3-2026 = time-barred (unless income > Rs 50 L).
Result. 3-year standard time-bar applies.
Illustration — Illustration 2 — 10-year extended for high-value
Facts. B's AY 2017-18; escaped income Rs 80 L represented in property.
Finance Act 2026: Section 149 reassessment time-limit framework refined by FA 2026 to align with the section 148/153 quarter-end-plus-3-months framework for court / appellate-order-driven reassessments. The FA 2021 substantive reassessment framework (3-year / 10-year limits) remains substantively intact.
Effective: 1 April 2026
Category: Reassessment / Time-bar
Practitioner Commentary:
Section 149 continues to govern the OUTER limitation framework (3 years / 10 years where escaped income >= Rs 50 lakh). FA 2026 refinement is procedural — for the specific case of court / appellate-order-driven reassessments, the inner quarter-end-plus-3-months framework applies. Practitioners must track both the outer and inner time-bars.

WORKED EXAMPLES
Illustration — Illustration 1 — Standard 3-year time-bar
Facts. A's AY 2022-23; notice considered 2025-26.
Computation.
End of AY 2022-23 = 31-3-2023.
3 years from end = 31-3-2026.
Notice by 31-3-2026 = within time-bar.
Post 31-3-2026 = time-barred (unless income > Rs 50 L).
Result. 3-year standard time-bar applies.
Illustration — Illustration 2 — 10-year extended for high-value
Facts. B's AY 2017-18; escaped income Rs 80 L represented in property.
Computation.
End of AY 2017-18 = 31-3-2018.
10 years from end = 31-3-2028.
Income > Rs 50 L threshold satisfied.
Asset = immovable property (within s. 149(3)).
Notice by 31-3-2028 = within time-bar.
Result. 10-year extended applies; preserve evidence of income / asset threshold.
Illustration — Illustration 3 — Rajeev Bansal TOLA framework
Facts. C's AY 2013-14; transitional matter.
Computation.
Pre-FA 2021 — 6-year time-bar standard, 16-year for foreign assets.
TOLA extended limitation up to 31-3-2021.
FA 2021 — new 10-year framework from 1-4-2021.
Rajeev Bansal — AY-wise operative matrix.
AY 2013-14 — TOLA-extended notice may be valid; AO must justify s. 149(1)(b) threshold.
Result. Transitional AYs need careful Rajeev Bansal analysis.
Illustration — Illustration 4 — Section 153A search assessment exception
Facts. D — search under s. 132; AY 2018-19 reassessment via s. 153A.
Computation.
S. 149(2) — Section 149 does NOT apply to s. 153A / 153C search assessment.
Section 153A separate time-bar framework.
Time-bar measured from search date / relevant trigger.
Result. Search assessment time-bar separate from s. 149.
Illustration — Illustration 5 — Income threshold ambiguity
Facts. E's AY 2018-19; escaped income Rs 45 L (below threshold); 5 years lapsed.
Computation.
S. 149(1)(a) — 3-year time-bar applies (income < Rs 50 L).
5 years > 3 years → time-barred.
AO cannot invoke 10-year extended.
Income threshold rigorously applied.
Result. Income threshold creates cliff; below Rs 50 L = standard 3-year time-bar.

FA 2026 AMENDMENT — COMMENTARY
Finance Act 2026: Section 149 reassessment time-limit framework refined by FA 2026 to align with the section 148/153 quarter-end-plus-3-months framework for court / appellate-order-driven reassessments. The FA 2021 substantive reassessment framework (3-year / 10-year limits) remains substantively intact.
Effective: 1 April 2026
Category: Reassessment / Time-bar
Practitioner Commentary:
Section 149 continues to govern the OUTER limitation framework (3 years / 10 years where escaped income >= Rs 50 lakh). FA 2026 refinement is procedural — for the specific case of court / appellate-order-driven reassessments, the inner quarter-end-plus-3-months framework applies. Practitioners must track both the outer and inner time-bars.
