“Section 27(3)”

Income is taxable only when it represents real income, not notional income. It accrues only when there is a vested right to receive it, typically upon the occurrence of a transfer or event, rather than merely on a time basis.

The Supreme Court established the foundational test for distinguishing between capital and revenue expenditure, holding that the aim and object of the expenditure and whether it brings into existence an asset or an advantage of an enduring nature determines its character, irrespective of the payment method. An advantage lasting five years or more can be considered enduring.

Rule 27 of the ITAT Rules allows a respondent to defend a favourable order of the CIT(A) by raising grounds decided against them, even without filing an appeal or cross-objection. Such issues can be raised orally and for the first time before the Tribunal.

The Assessing Officer is not bound by the technical rules of evidence and pleadings and is entitled to act on material that may not be admissible as evidence in a court of law during assessment proceedings.

Where civil or evil consequences ensue from the action of a statutory authority, the principles of natural justice must be followed, even if not explicitly stated in the statute. Failure to comply with these principles may render a statute ultra vires Article 14 of the Constitution.

Income from letting out immovable property, even with ancillary services, is taxable as 'Income from House Property' if the dominant intention is to exploit the property itself, not to run a complex business providing integrated services. The classification depends on the assessee's primary object in exploiting the property.

Section 282 of the Income Tax Act, 1961 specifies the modes for serving notices, including by post or summons under the Code of Civil Procedure. A valid service of notice is essential for assessment or reassessment proceedings, and its absence renders such proceedings bad in law.

The validity of an approval for reassessment proceedings under section 151 of the Income Tax Act, 1961, hinges on whether it bears the signature, including a digital signature, of the Principal Commissioner of Income Tax.
