C.A. No. 001440 / 2018
Under Indian income tax law, Rule 8D of the Income Tax Rules, 1962 — being subordinate legislation prescribing the methodology for computing disallowable expenditure under Section 14A — operates only prospectively from the date of its notification, and cannot be applied to assessment years preceding its insertion, even though Section 14A(1) itself has retrospective operation. As analyzed on casestatus.in, a procedural or machinery rule framed under a charging provision does not automatically inherit the retrospectivity of the parent section where the rule imposes a new computational liability. Accordingly, sub-sections (2) and (3) of Section 14A along with Rule 8D apply only from Assessment Year 2007–08 onwards.
