Interest-tax amendment expands covered interest types and broadens definition of specified financial institutions, altering temporal application. The Finance (No. 2) Act, 1980 amends the Interest-tax Act, 1974 by expanding the definition of interest to include interest under subsection (1B) of section 42 of the Reserve Bank Act, clarifying that interest on term loans sanctioned before an earlier cutoff is within scope where repayment is over not less than three years and defining 'term loan' as not repayable on demand, and by adding specified industrial financial institutions to a defined category; these substitutions take effect from the operative date specified in the amendment.
