Stamp duty value treated as a notional benchmark for tax valuations, overriding conflicting valuation laws for tax purposes.
Section 2(105) defines stamp duty value as the value adopted, assessed or assessable by a Central or State authority for stamp duty on immovable property, where "assessable" is expressly a notional value the authority would have adopted if referred the matter, and that definition applies irrespective of anything to the contrary in any other law in force.

Holding-period tiers determine capital gain classification with a shorter threshold for listed securities and specific fund units.
Definition of short-term capital asset establishes a two-tier holding-period regime for capital gains classification, retaining a general holding-period test and a shorter test for listed securities, units of the Unit Trust of India, units of equity-oriented funds and zero-coupon bonds; detailed rules determine inclusion, exclusion and commencement of holding periods on liquidation, corporate reorganisations, conversions, allotments, renunciations, free allotments and GDR redemptions, with certain technical matters deferred to prescribed rules.

Definition of company in which the public are substantially interested: drafting variance may create conjunctive interpretation risk affecting tax classification.
Clause 2 supplies a comprehensive glossary for the Income-tax Act, 2025, defining terms such as company, capital asset, income and virtual digital asset, often with cross-references, provisos and delegated prescriptions; clause 2(29)'s categories for a company in which the public are substantially interested are materially consistent between Bill and Act, but the Bill's connector wording risked a conjunctive reading of alternative tests that the Act's later disjunctive phrasing rectifies, creating interpretive consequences for tax classification and related compliance.

Definition of company clarified; temporal qualification in transitional limb may narrow which historic entities remain within tax scope.
Section 2 supplies statutory definitions that determine tax coverage. The definition of company comprises Indian companies, foreign bodies corporate, entities assessable as companies under the repealed Act, and Board declared entities. The Bill adds a temporal qualification limiting entities assessed under the prior Act to particular assessment years; the Act text omits this qualification. Scattered drafting and cross reference differences exist. Operational consequences hinge on threshold facts (shareholding, listing, assessment history, population/distance tests) and on unstated transitional provisions.

Capital asset definition updated to include IFSC-regulated funds and broaden unit-linked policies, affecting capital gains treatment.
The Act retains an inclusive definition of capital asset with exceptions for stock-in-trade, specified personal effects and certain agricultural land, while refining the securities limb to expressly include securities held by FIIs and investment funds regulated under SEBI or IFSC regimes and removing a temporal issuance-date qualifier for unit-linked insurance policies, thereby broadening the category of policies treated as capital assets; numerous drafting and cross-reference clarifications aim to reduce interpretive uncertainty.
