Tax relief for export turnover allows deduction when exports rise over prior year, subject to government rates and a cap. A new provision grants a tax deduction where an assessee's export turnover in a previous year exceeds that in the corresponding base year by the specified threshold; applicable to Indian companies and resident persons for the assessment year beginning 1 April 1983 and the four subsequent years. The Central Government will notify the goods, export destinations and rates, having regard to manufacturing costs, foreign prices, market development and foreign-exchange needs. The deduction is capped at a proportion of tax otherwise payable on export profits, with rules for computing those profits to be made by the Board.
