When the assessee's own funds exceed the investments, a presumption can be drawn that the investments were made out of the assessee's own funds and no proportionate disallowance is warranted under Section 14A of Income Tax Act 1961 (ITA'61). Disallowance of expense under Section 14A of Income Tax Act 1961 (ITA'61) read with Rule 8D of Income Tax Rules 1962 (ITR'62) is not justified, when the assessee has ample own funds to make the investments was held in the case of Supreme Court in the case of South Indian Bank Limited.
Further disallowance under Section 14A read with Rule 8D should not be done based on the total investments but only the investments that yield exempt income during the year. Relying on the judgment of the Delhi High Court in the case of Cargo Motors (P.) Limited. The same was held in the case of GUJARAT STATE PETRONET LIMITED Vs DEPUTY COMMISSIONER OF INCOME TAX [2025-VIL-1463-ITAT-AHM]. Section 14 of Income Tax Act 1925 (ITA'25) corresponds to Section 14A of Income Tax Act 1961 (ITA'61) and squarely holds the same position.
