Interpretation of penalty for failure to furnish return: extended filing window does not prevent penalty for missing original filing deadline

Interpretation of the interaction between the statutory time-limit for filing returns and the penalty provision: strict construction requires reading the initial filing deadline as effective and its sanction preserved, so the extended filing window provided elsewhere does not negate default for penalty purposes; identical wording across provisions supports a confined, consistent meaning rather than projecting the extended filing period into the penalty clause; contextual interpretation and legislative intent justify treating late filing within the extended four-year window as not preventing imposition of penalty for failure to file within the original prescribed time, and the penalty therefore remains attractable.

Issues: Whether a return filed under section 139(4) of the Income-tax Act, 1961 (i.e., filed after the time allowed under section 139(1) but before the expiry of four years from the end of the assessment year) is to be treated as having been filed "within the time allowed by sub-section (1) of section 139" for the purposes of avoiding penalty under section 271(1)(a).

Analysis: Section 139 provides three temporal stages for valid returns: within the time under sub-section (1), in response to a notice under sub-section (2), or thereafter under sub-section (4) but before assessment and within four years from the end of the assessment year. Section 271(1)(a) contains two clauses distinguishing (i) failure to furnish any return and (ii) failure to furnish a return "within the time allowed" by sub-section (1) of section 139. The language of the second clause"within the time allowed . . . by sub-section (1) of section 139"plainly refers to the period specified in sub-section (1) (including any extension granted under the proviso to sub-section (1)), and does not encompass the separate remedial filing period under sub-section (4). Reading the clauses together prevents redundancy and gives effect to the legislature's explicit choice of words. Sub-section (4) grants locus poenitentiae and renders a late return legally effective for assessment, but it does not obliterate the distinct temporal limit in sub-section (1) or erase other statutory consequences of default. The compensatory interest provision in the proviso to section 139(1) is distinct in nature from the punitive scheme under section 271(1)(a); treating interest as punishment would be incorrect. Reliance on observations in Kulu Valley Transport Co. (interpreting a different provision in a different context) cannot be extended to alter the plain meaning of section 271(1)(a) read with section 139.

Conclusion: Filing a return under section 139(4) within four years does not amount to filing "within the time allowed by sub-section (1) of section 139" for the purposes of section 271(1)(a); a person who files only under section 139(4) after the time allowed under section 139(1) remains liable to penalty under the second clause of section 271(1)(a).

Ratio Decidendi: For the purpose of section 271(1)(a) the expression "within the time allowed by sub-section (1) of section 139" refers exclusively to the period specified in section 139(1) (including any extensions under its proviso) and does not include the later remedial filing period under section 139(4); consequently late filing under section 139(4) does not preclude liability to penalty under section 271(1)(a).
