Sec. 28, 56 & 80-IA of Income Tax Act, 1961—Income from other sources — The head "Income from other sources" is like a residuary clause and the income which cannot be attributed or related to any specified and defined head of income, then only such income can be brought to tax under section 56 which itself provides both an inclusive and exclusive definition. Interest income earned by the assessee in the ordinary course of business, cannot be said to be excluded from the head "Income from business or profession" in Part D, comprising of sections 28 to 44DB in Chapter IV, which deals with computation of the total income in the heads of income as per section 14. Thus, interest income earned in the ordinary course of business is excluded from section 56. An interest income earned by the assessee or received by the assessee during the year in question, in the ordinary and regular course of business is an integral part of business income itself—AVM CINE PRODUCTS Vs.
