Companies profits surtax amendment increases surcharge rate and revises balance-sheet capital computation and schedule rules. Amendments to the Companies (Profits) Surtax Act, 1964 increase the surtax rate and revise Schedule provisions: a First Schedule rule replaces an aggregate deduction formula with a direct expenditure deduction; the Second Schedule changes cross references, omits two clauses, inserts Rule 1A (deemed effective earlier) requiring reduction of computed capital where specified balance-sheet credits are not made or are understated, and narrows rule-based capital reductions to reductions of paid-up share capital.
