Arm's length pricing: multi year ALP option expands certainty and permits roll forward of transfer pricing determinations.
Clause 166 authorises the Assessing Officer to refer international and specified domestic related party transactions to a Transfer Pricing Officer for determination of the arm's length price, subject to prior approval; mandates notice, hearing, prescribed transfer pricing methods, and communication of the TPO order to AO and assessee; empowers the TPO to examine unreported transactions and to validate a taxpayer's option to apply a determined ALP to similar subsequent years, with rectification powers and corresponding AO amendment obligations, and permits issuance of Board guidelines to implement the multi year regime.

Arm's length price determination: new clause refines methods and AO powers, emphasizing documentation and prescribed procedures.
Determination of Arm's Length Price requires selecting the most appropriate method from prescribed alternatives based on the transaction's nature, associated enterprise class, and functional analysis; where a single comparable price is found it is the arm's length price subject to a prescribed tolerance, while multiple prices must be reconciled in a prescribed manner. The tax authority may determine ALP during assessment if methods were not followed or documentation is inadequate, but must issue a show cause notice before adjustment; adjustments permit recomputation of total income and restrict deductions on enhanced income, with safeguards to prevent double adjustment.

Specified domestic transaction: extending transfer pricing to high-value related-party domestic dealings, subject to arm's length compliance.
Clause 164 defines specified domestic transaction by enumerating categories of non-international related-party dealings brought under transfer pricing when aggregate annual value exceeds a high-value threshold, includes a residual prescription power to notify additional transactions, and requires contemporaneous documentation and benchmarking to ensure compliance with the arm's length principle.

International transaction scope expanded broadens transfer pricing coverage to intangibles and indirect dealings, including restructuring and financing arrangements.
Clause 163 defines international transaction expansively to include tangible and intangible property (expressly including transfer), capital financing, services, business restructuring, cost sharing and any transaction affecting profits, income, losses or assets; it reproduces an illustrative list of intangibles and contains a deeming rule treating dealings with third parties as international transactions where terms are determined with or pursuant to an associated enterprise, thereby widening transfer pricing coverage and anti avoidance reach.

Presumptive taxation: partner remuneration and interest cannot be treated as individual business turnover for presumptive tax purposes.
Section 44AD applies only where the assessee carries on an eligible business and has actual turnover or gross receipts attributable to that assessee. Remuneration and interest paid by a partnership firm to a partner arise from the firm's accounts and partnership agreement; although Section 28(v) taxes such receipts in the hands of the partner, that deeming does not convert them into the partner's turnover or gross receipts for Section 44AD. Section 40(b) governs firm deductibility but does not create an independent business activity in the partner; hence such receipts cannot be subjected to Section 44AD presumptive taxation.

Associated enterprise definition expands transfer pricing scope to include specified domestic transactions and indirect control.
Clause 162 defines associated enterprise through a general limb covering direct or indirect participation in management, control or capital and a list of deeming provisions-equity thresholds, significant loans and guarantees, board control, dependence on intangibles, supply and sales dependence, and familial/HUF control-while expressly extending the concept to specified domestic transactions and retaining prescribed catch-all and subjective influence tests that may require further guidance.

Arm's length price requirement drives transfer pricing adjustments to prevent profit shifting and protect the tax base.
Clause 161 mandates computation of income and the allowance of expenses or interest for international and specified domestic transactions among associated enterprises with reference to the arm's length price, requires arm's length allocation for shared costs or services, and prohibits transfer pricing adjustments that would reduce taxable income or increase losses, thereby strengthening scrutiny of intra group cost allocations and deductions to prevent profit shifting.

Unilateral double taxation relief limits credit to the lower of domestic or foreign tax rates and requires proof of foreign tax payment.
Clause 160 provides unilateral relief for Indian residents and non-resident partners taxed on foreign income where no DTAA exists, limited to the lower of the Indian tax rate or the foreign tax rate, requires proof of foreign tax payment, and defines key terms to include excess profits or business profits taxes; it modernizes terminology and omits a prior country-specific carve-out, while raising evidentiary and computational ambiguities.

Double taxation relief framework modernised: new clause clarifies treaty adoption, anti abuse safeguards, and documentation requirements.
Clause 159 empowers the Central Government to enter into and adopt agreements with foreign countries and notified specified territories, and permits specified domestic associations to enter into sectoral agreements subject to governmental adoption and notification. Agreements may provide relief from double taxation, avoidance of double taxation constrained by anti abuse safeguards, exchange of information to prevent evasion, and mutual assistance in tax recovery. The Act's provisions apply to the extent more beneficial to the taxpayer, but anti abuse measures in Chapter XI apply notwithstanding such benefit. Non residents must furnish a certificate of residence and prescribed documentation to claim treaty relief.

Treaty interpretation and anti-abuse primacy clarified: government may adopt association agreements while preserving treaty benefit limits.
Clause 159 authorises the Central Government to enter into agreements with foreign countries or notified territories and to adopt agreements between notified specified associations for double taxation relief, exchange of information, and mutual assistance in recovery. Taxpayers may claim the more beneficial of domestic law or a notified agreement, subject to documentary requirements for non-residents and the primacy of chapter-level anti-abuse provisions. A four-tier interpretive hierarchy for treaty terms is provided, with retrospective effect from the agreement's commencement.

Relief from taxation on foreign retirement accounts aligns Indian tax timing with foreign withdrawal taxation to prevent double taxation.
Clause 158 aligns Indian taxation of income from foreign retirement accounts with the foreign tax event by restricting relief to specified accounts in notified countries opened while the taxpayer was non resident, and by delegating timing and procedural details to rules to prevent double taxation, address timing mismatches, and guard against abuse.

Relief for irregular salary receipts: claim based allocation to prior years with computation and procedures delegated to rules.
Clause 157 provides relief where lump sum receipts (arrear or advance salary, salary for over twelve months, profits in lieu of salary, and arrears of family pension) cause an assessment at a higher rate. Relief is claim based on application to the Assessing Officer and requires allocation of amounts to earlier years; the Assessing Officer grants relief as prescribed in rules. An anti abuse exclusion denies relief where a deduction for the same amount has already been claimed, and computation, procedural steps and particulars (e.g., Form 10E practice) are to be specified by rules.

Mutuality doctrine shields club-member transactions from GST; statutory deeming fiction held unconstitutional, retrospective levy invalid.
The Kerala High Court held that the doctrine of mutuality insulates transactions between an association and its members from GST because the concepts of "supply" and "service" require distinct persons; statutory deeming provisions treating associations and members as separate persons are ultra vires Article 246A and related constitutional provisions, and retrospective application of those amendments is invalid as unfair and contrary to the rule of law.

Rebate for resident individuals: expanded two-tier relief and tapered withdrawal to avoid abrupt tax cliffs.
Clause 156 creates a two-tier rebate: a general rebate for resident individuals below a base threshold and an enhanced rebate for taxpayers opting into the new tax regime with a higher threshold and larger maximum rebate. The enhanced rebate includes a tapering mechanism for incomes above its threshold and an express cap preventing the rebate from exceeding actual tax liability, with computation rules tied to the new-regime tax rates.

Rebate allowance framework modernisation - rebates applied after tax computation and capped to prevent negative tax liability.
Allowance of rebates is enabled by Clause 155, which permits rebates to be deducted from income-tax computed on total income after tax computation and before other chapter deductions, and caps aggregate rebates so they cannot exceed the tax computed prior to rebates; the substantive conditions and limits are delegated to Section 156.

Taxation of member's share: entity-level tax exempts members, unless the entity is untaxed or taxed below top rate.
Clause 310 establishes that a member's share of income from an AOP/BOI is exempt from tax in the member's hands when the association/body is taxed on that income; if the AOP/BOI is not chargeable to tax the member's share is taxed in the member's hands; and if the AOP/BOI is taxed at the maximum marginal rate the member's share is excluded from his total income, otherwise the member's share is included in his total income.

Deduction for disability: standardized tax relief retained with mandatory medical certification and prescribed certificate submission.
Clause 154 allows resident individuals certified by a medical authority as persons with disability or severe disability to claim a fixed deduction, contingent on furnishing the prescribed certificate with the return and on certificate validity and reassessment rules; definitions are cross referenced to a Bill provision for consistency.

Deduction for interest on deposits expanded to include senior citizens and time deposits, consolidating small-saver relief.
Clause 153 provides a statutory deduction for interest on deposits to individuals, senior citizens, and HUFs, specifying eligible institutions (banks, cooperative banking societies, and post offices), preserving denial of deductions for interest held by or on behalf of firms, AOPs, or BOIs, and defining time deposits. It consolidates prior disparate provisions by including senior citizens within the same clause with expanded coverage for time deposits, while maintaining the existing deduction treatment for non senior individuals and HUFs.

Patent royalty deduction for resident inventors: capped, certified relief tied to repatriated foreign receipts and compulsory licence limits.
Clause 152 provides a statutory deduction for resident individual patentees in respect of royalty from patents registered on or after 1 April 2003, subject to a statutory annual ceiling and procedural certification. Deductions in compulsory licence cases are limited to Controller determined royalty; foreign-sourced receipts qualify only to the extent repatriated in convertible foreign exchange within the prescribed period and supported by prescribed certification. Definitions exclude capital gains and sales proceeds from the scope of "royalty," and certification by prescribed authorities is required with the return.

Deduction for authors' royalty income limited by a fixed cap and repatriation plus certification requirements.
Clause 151 grants a deduction to resident individual authors for professional income from copyright assignment or royalties for literary, artistic, or scientific books (excluding textbooks), subject to a fixed monetary cap and a royalty to sales limit for non lump sum receipts. Foreign income qualifies only if repatriated in convertible exchange within a prescribed period and accompanied by prescribed certification, and claimants must submit payer verified certificates with returns; double deduction for the same income is expressly prohibited.
