    Power to frame schemes expands executive authority to enable faceless, technology-driven tax administration and modify statutory application.
    Clause 532 grants the Central Government authority to make schemes for any purpose of the Act to enhance efficiency, transparency and accountability by eliminating taxpayer interface and optimising resources, and to issue notifications modifying the application of any provision of the Act to give effect to such schemes; it also permits amendment of schemes under the Income-tax Act, 1961 and requires that notifications be laid before each House of Parliament.

    Withdrawal of approvals: authorities may rescind statutory tax approvals after recording reasons and giving a fair hearing.
    Clause 529 authorises the Central Government, the Board, or income-tax authorities to withdraw any approval under the Act at any time after recording reasons and giving the assessee a reasonable opportunity of being heard, even if the enabling provision lacks an express withdrawal clause. The provision mandates recorded reasons and a hearing but leaves "approval" undefined, does not specify substantive grounds for withdrawal, and does not prescribe a limitation period, which may raise uncertainty and prompt judicial scrutiny of procedural adequacy.

    Condonation of delay: authority may excuse late tax approvals for sufficient cause, subject to discretionary review and safeguards.
    Clause 528 permits the Central Government or the Board to condone delays in obtaining approvals required before a specified date under the Act for "sufficient cause," vesting discretionary power in the same authority to excuse late applications across a broad range of approvals while leaving "sufficient cause," procedural steps, time limits and appeal mechanisms undefined.

    Executive discretion in tax exemptions for mineral oil sector enables tailored fiscal relief to investors and service providers.
    Clause 527 vests the Central Government with discretionary power to grant exemptions, reductions or other modifications in income tax for persons engaged in prospecting, extraction or production of mineral oils, including operators, service providers, suppliers and their employees; notifications must be laid before Parliament and key terms like "mineral oil" and "status" are defined or cross referenced in the Bill.

    Bar on civil suits prevents civil court challenges to tax proceedings, preserving exclusive statutory remedies and good faith immunity.
    The provision bars any civil suit to set aside or modify "any proceeding taken or order made" under the Act and grants immunity to the Government and its officers for acts done or intended to be done in good faith, channeling challenges to the statutory appellate and revisionary framework while preserving writ review for ultra vires, mala fide, or constitutional breaches.

    Authorisation for multi-person searches: single authorisations allowed, but assessments must be made separately for each person.
    Clause 525 permits a single search or requisition authorisation to name multiple persons without requiring separate instruments, and provides that such joint naming does not, by itself, constitute authorisation against an AOP or BOI. Notwithstanding a consolidated authorisation, assessment or reassessment must be made separately in the name of each person mentioned, preserving individualized tax liability determinations while allowing administrative consolidation of search procedures.

    Rebuttable presumption in tax searches shifts evidentiary burden to taxpayers and explicitly covers virtual digital assets.
    Clause 524 establishes a rebuttable presumption that items found in search or survey-books, documents, money, bullion, jewellery, other valuables and virtual digital assets-belong to the person in whose possession they were found; that contents of books and documents are true; that signatures and handwriting are authentic; and that stamped, executed or attested documents were duly executed, with identical presumptions applying to items requisitioned to officers as if discovered in a search.

    Deeming validity of notice: participation or cooperation bars later objections unless raised before assessment completion.
    Clause 523 creates a deeming fiction that an assessee's appearance in proceedings or co-operation in an inquiry shall be treated as valid and timely service of any statutory notice, and it precludes the assessee from later objecting that the notice was not served, not timely served, or served improperly; however, this preclusion does not apply where the assessee raises the objection before completion of the assessment or reassessment.

    Substantial compliance preserves tax proceedings despite minor procedural errors when the instrument fulfils legislative intent.
    Clause 522 preserves the validity of returns, assessments, notices, summonses and other proceedings despite clerical, typographical or similar procedural defects, provided the document or action is in substance and effect in conformity with the intent and purposes of the Act; it does not cure defects that go to jurisdiction, authority, limitation, or breaches of natural justice, and mirrors Section 292B to maintain continuity of judicial interpretation and application.

    Exclusion of probationary relief bars adult tax offenders from probationary provisions, preserving minors' exception and updating criminal code reference.
    The clause mandates that the Probation of Offenders Act and the analogous provision in the new criminal procedure code shall not apply to persons convicted under the Income Tax Bill, 2025, except for those under eighteen, thereby removing judicial discretion for adult tax offenders, updating statutory references, and preserving a minors' exception while raising procedural questions on age determination and scope.

    Jurisdictional threshold: income tax offences must be tried by a Judicial Magistrate of the first class, altering forum nomenclature.
    Clause 520 mandates that no court inferior to a Judicial Magistrate of the first class shall try any offence under the Income Tax Bill, 2025, creating a uniform jurisdictional threshold for all tax offences. The provision modernizes terminology compared with Section 292 of the 1961 Act by omitting presidency magistrates, aligning with the CrPC framework and metropolitan magistrates' equivalence, while leaving potential ambiguities about special statute courts and transitional application. Its practical effect is to require complaints be filed before competent magistrates and to enable jurisdictional challenges where proceedings are instituted in inferior forums.

    Immunity from prosecution: conditional grants require full and true disclosure and are revocable if falsehood or concealment is found.
    Immunity from prosecution allows the Central Government to grant discretionary, conditional immunity to persons concerned in concealment of income or tax evasion in exchange for a full and true disclosure, with written reasons required for the grant; acceptance limits prosecution and penalty to the scope specified, while failure to fully comply permits the government to record a finding and withdraw immunity, rendering the person liable to trial and penalty as if immunity had never been granted.

    Indemnity for withholding agents protects deductors from civil claims when acting lawfully under the tax statute.
    Clause 518 of the Income Tax Bill, 2025 provides a statutory indemnity for persons who deduct, retain, or pay tax in pursuance of the tax statute in respect of income belonging to another person, serving as a defence against civil claims by the income recipient where the agent acts lawfully; the protection is conditional on actions being within the scope of the statute and leaves unresolved issues about consequential losses, claim procedures, and interaction with other legal remedies.

    Receipt obligation: mandatory issuance of receipts for any tax money paid or recovered, securing payment evidence and taxpayer protection.
    The provision mandates that a receipt shall be given for any money paid or recovered under the Income Tax Bill, 2025, covering voluntary payments and enforced recoveries under the Act. The clause is mandatory but silent on form, content, timing, issuing authority, mode of delivery, and consequences for non-issuance; subordinated rules and administrative practice-including electronic acknowledgments-are expected to fill these operational gaps. The receipt serves as an acknowledgement and evidentiary record rather than an automatic discharge of liability.

    Rounding off rules: ignore paise then round to nearest ten rupees, making the rounded figure legally operative.
    The provision applies rounding to computed total income and to amounts payable or refundable by first ignoring paise and then rounding the rupee amount to the nearest multiple of ten rupees-rounding up where the units digit is five or more and rounding down where it is less than five-and declares the rounded amount to be the deemed operative total income or amount payable or refundable for all purposes under the Act.

    Right of representation: statutory authorisation and disqualification framework balancing access to representation with safeguards.
    The statute permits an assessee to appear by an authorised representative across all proceedings while preserving mandatory personal attendance for oath examination; it defines eligible representatives (including professionals, bank officers, relatives, legacy practitioners and any persons as prescribed), enumerates exhaustive exclusions and disqualifications to prevent conflicts of interest, distinguishes disciplinary regimes for professionals and nonprofessionals (with Rule 52 designating prescribed tax authorities to disqualify nonprofessionals), and mandates procedural safeguards including a hearing and appeal mechanism, while carrying forward prior disqualifications.

    Registered valuer representation enables technical valuation expertise in tax proceedings, subject to personal-examination exception and updated registration framework.
    Clause 513 grants an assessee the discretionary right to attend valuation-related proceedings before income-tax authorities or the Appellate Tribunal through a "registered valuer," excludes cases where personal attendance is required for examination on oath or affirmation, and defines "registered valuer" by reference to section 514 of the Bill, thereby creating a self-contained regime that modernizes registration, oversight, and professional standards for valuers.

    Public disclosure of tax offenders can deter non-compliance while imposing reputational consequences under discretionary publication powers.
    Clause 512 empowers the Central Government to publish names and particulars of assessees when it considers such publication necessary or expedient in the public interest, subject to a safeguard that penalty-related publication await exhaustion or non-pursuit of appellate remedies, and permits publication of partners, directors and other associated persons if circumstances justify it. The clause modernises language and cross-references from Section 287 of the 1961 Act while preserving substantive continuity, raising interpretive concerns about the breadth of "particulars" and the subjectivity of "public interest."

    Country-by-Country reporting requires multinational groups to submit consolidated jurisdictional tax and economic data for risk assessment.
    Clause 511 mandates Country-by-Country (CbC) reporting by parent entities or alternate reporting entities resident in India and requires Indian constituent entities to notify the tax authority of the parent or ARE. It prescribes report contents-aggregate jurisdictional financial and economic indicators, constituent identification, and business activities-provides a secondary filing route where the parent's jurisdiction lacks filing or exchange, allows designation of a single Indian filer, sets a revenue threshold for applicability, and grants verification powers to the authority, with procedural details to be prescribed.

      SCHEDULE II INCOME NOT TO BE INCLUDED IN TOTAL INCOME

      Income-tax Act, 2025

      At a Glance

      SCHEDULE II sets out classes of income that are excluded from "total income" for income-tax purposes. The Bill (Old Version) and the enacted Act differ in several material respects affecting life-insurance exclusions, pension/NPS entries, references to International Financial Services Centre (IFSC) entities, and the inclusion of equalisation-levy income. Affected parties include policyholders, insurers, employers, employees, pension subscribers, IFSC entities and tax authorities. Effective dates are stated within specific entries (for example, policy issue periods and 1 April 2002/2023) where provided; no single overarching commencement date for the Schedule is stated in the Bill text.

      Background & Scope

      Statutory hook: SCHEDULE II (See section 11) - "Income not to be included in total income." The Schedule lists categories of exempt income (column B) subject to conditions (column C). Definitions and notes at the end assign meanings to terms used in the table. The Bill (Old Version) is the source document for this commentary. Any differences vis-`a-vis the enacted Act are identified only insofar as both texts were provided; where a detail is absent in the Bill text, the phrase "Not stated in the document." has been used.

      Statutory Provision Mode

      Text & Scope

      The Schedule enumerates 16 heads of income excluded from total income, including: agricultural income; sums under life-insurance policies (with sub-conditions tied to period of issue, premium-to-sum-assured ratios and aggregate premium ceilings); provident fund and recognised provident fund payments (with carve-outs for interest on large contributions on/after 1 April 2021); payments under Sukanya Samriddhi, National Pension System (NPS) Trust, Agniveer Corpus Fund, approved superannuation funds; scholarships; awards/rewards instituted or approved by government; interest or other receipts on specified government securities and deposits; interest on gold bonds/certificates; interest on bonds issued by local authorities or State Pooled Finance Entities; income on transfer of certain UTI units; income chargeable to equalisation levy (new insertion); and specific categories u/s 10(15) and related provisions of the 1961 Act as applicable.

      Interpretation

      The text frames exclusions as conditional: each head is subject to prescribed conditions and definitions in accompanying notes. Legislative intent, as discernible from the Bill text, is to preserve traditional exemptions (agriculture, certain pensions, scholarships, specified government securities) while tightening or clarifying tax-exempt treatment for life-insurance receipts and retirement/savings vehicles by reference to issue dates, premium ratios, aggregate premium ceilings and contribution thresholds. The insertion of equalisation-levy related exclusion (Sl. No. 15) signals explicit recognition of overlap between equalisation-levy chargeability and income-tax neutrality for certain cross-border digital services.

      Exceptions/Provisos

      Key carve-outs and conditions provided in the Bill include:

      • Life-insurance sums excluded only if policies meet period-specific premium-to-sum-assured ratios and, for certain periods, aggregate premium ceilings (Rs. 2,50,000 or Rs. 5,00,000) - and certain sums (section 127 receipts; Keyman policies) are expressly ineligible.
      • Portions of interest on provident fund/recognised provident fund balances attributable to contributions on/after 1 April 2021 are not eligible for exclusion where contributions exceed specified thresholds (Rs.5,00,000 / Rs.2,50,000) and the amount not excluded is to be computed as prescribed.
      • NPS payments excluded only to the extent they do not exceed 60% of the total amount payable on closure/opt-out.
      • Approved superannuation fund payments are exempt only in specified circumstances (death, commutation at retirement/age, refund in limited cases, transfer to specified pension schemes).
      • Equalisation-levy related incomes are excluded only where not chargeable as royalty/FTS in India under agreements notified u/s 159 (explicit exception in Sl. No. 15).

      Illustrations

      • Example 1: A unit-linked life policy issued on 1 Oct 2023 with annual premium such that premium-to-sum-assured ratio is 12% and aggregate premium per tax year is Rs.2,00,000 - the Bill permits exclusion if it meets the Item 2 conditions (unit-linked post-1-April-2023: ratio <=15% for special, <=10% for others; aggregate <=Rs.2,50,000 for ULIP). Whether treated as "special policy" depends on disability/disease status u/rs - Not stated in the document.
      • Example 2: An employee receives accumulated recognised provident fund balance including interest attributable to contributions of Rs.6,00,000 made on/after 1 April 2021 in a year when no employer contribution was made - interest attributable to that contribution is not eligible for exclusion (threshold exceeded Rs.5,00,000); the portion not excluded to be computed as prescribed (procedure Not stated in the document).

      Interplay

      The Bill references other statutory instruments and provisions: Section 11 (hook), Section 127 (for life-insurance ineligibility), Schedule XI para 8, Schedule XV (definition of "actual capital sum assured"), Insurance Regulatory regulations, the Provident Funds Act, Government Savings Promotion Act (Sukanya Samriddhi), Dept. notifications regarding NPS (notifications not reproduced in the Bill text), Finance Act, 2016 (equalisation levy Chapter VIII) and section 159 agreements. The Bill contemplates Board guidelines for removal of difficulties. Where computation methods are required ("as prescribed"), the Bill defers to rules/regulations; these procedural details are Not stated in the document.

      Differences between the Bill (Old Version) and the Enacted Act - Practical Impact

      TopicBill (Old Version)Act (2025) - Differences & Practical Impact
      Reference to IFSC in life-insurance entryExclusion clause expressly excludes policies issued by "International Financial Services Centre insurance intermediary office" from the general test; IFSC office language appears within clause (a).

      The Act broadens IFSC coverage differently (references to "International Financial Services Centre Insurance Office") and later adds a special carve-out that aggregate premium conditions do not apply to policies issued on or after 1 April 2025 by the IFSC Insurance Office.

      Practical impact: IFSC-issued policies post-1-Apr-2025 enjoy relaxed aggregate-premium limits under the Act versus the Bill - this benefits IFSC policyholders and insurers.

      Section reference for ineligible insurance sumsIneligibility lists section 127 (no subsection reference) and Keyman policies.

      The Act specifies "section 127(4)" as ineligible; this narrows or clarifies which portion of section 127 is meant.

      Practical impact: narrower/clearer exclusion scope for section 127 receipts, reducing interpretive ambiguity.

      Aggregate premium thresholds for policies issued on/after 1-Apr-2023ULIPs: aggregate <=Rs.2,50,000; other policies: aggregate <=Rs.5,00,000.

      The Act restates these ceilings but then adds the IFSC carve-out for policies issued on/after 1-Apr-2025.

      Practical impact: domestic policyholders unchanged, IFSC policyholders gain advantage.

      NPS-related entries (Sl. Nos. 15 & 16)The Bill lacks specific entries for "lump sum amount" defined by a particular notification and for Unified Pension Scheme subscriber-specific references.

      The Act adds two discrete entries (Sl. Nos. 15 and 16) dealing with NPS payments to Unified Pension Scheme subscribers and "lump sum amount" per a departmental notification dated 24 Jan 2025.

      Practical impact: greater specificity and targeted exemption for Unified Pension Scheme subscribers under NPS, linking to a concrete notification (FX-1/3/2024-PR). This reduces uncertainty for affected NPS subscribers.

      Equalisation levy incomeBill includes Sl. No. 15 addressing income chargeable to equalisation levy.

      The Act omits the Bill's Sl. No. 15 equalisation-levy entry or shifts numbering; comparison shows the Act instead includes other NPS-related items.

      Practical impact: the treatment of equalisation-levy incomes requires reconciliation between Act text and prior Bill; taxpayers relying on the Bill's exclusion must verify the final Act wording (Not stated in the document).

      Practical Implications

      • Compliance and risk areas: Life-insurance exclusions carry detailed temporal and quantitative conditions (period of issue, premium-to-sum-assured ratio, aggregate premium ceilings). Insurers and policyholders must verify issue date classifications and compute premium ratios and aggregate premiums across the policy term. The explicit ineligibility for keyman policies and section 127 receipts increases scrutiny over policy ownership and assignment.
      • NPS and provident fund entries impose record-keeping obligations: authorities and subscribers must track contributions made on or after 1 April 2021 separately, and identify portions of interest attributable to contributions exceeding thresholds. The method of computing the amount not excluded is left to prescribed rules - until rules are notified, potential uncertainty persists.
      • Equalisation-levy clause (Sl. No. 15): taxpayers and digital service providers should reconcile equalisation-levy exposure and Income-tax chargeability; the clause excludes income chargeable to equalisation levy except where the income is otherwise taxable in India as royalty/FTS under notified agreements (thus creating an interplay with tax treaty determinations and notifications u/s 159).
      • IFSC references: the Bill treats certain IFSC insurance intermediary office receipts differently in the life-insurance entry (exclusion/inclusion language differs versus the Act). Parties operating within IFSCs should note the special treatment and any administrative guidance forthcoming.
      • Procedural uncertainty: multiple entries defer to "as prescribed" computations and to notifications by the Central Government; until those are issued, taxpayers face interpretation and compliance risk. The Board's power to issue binding guidelines (with Central Government approval) is preserved, indicating administrative rule-making will shape practical application.

      Key Takeaways

      • The Bill retains traditional exemptions (agriculture, scholarships, certain pension/retirement receipts) while imposing quantified tests on insurance exclusions (period-specific ratios and aggregate premium ceilings).
      • Interest on provident fund balances attributable to large post-1-April-2021 contributions is explicitly excluded from exemption, with thresholds (Rs.5,00,000 / Rs.2,50,000) and prescribed computation methods.
      • Equalisation-levy related income is newly addressed - excluded except where taxable in India as royalty/FTS under notified agreements.
      • Certain specific sums are expressly excluded from insurance exemption (section 127 receipts; Keyman insurance), tightening the prior broader language.
      • Several entries defer key operational questions to rules/notifications; substantial administrative guidance is required to operationalise the Schedule.
