Phased reduction of export profit deduction under section 80HHE reduces allowable relief annually and ends after final assessment year. Amendment to section 80HHE converts an absolute deduction into a time limited, phased relief by substituting wording to limit deduction 'to the extent of the profits' and by adding a new sub section specifying graduated extents of deduction for successive assessment years and termination after the final specified year; the Explanation to sub section (5) is amended to define 'computer software' to include recorded programmes and customised electronic data or similar products or services notified by the Board when transmitted or exported from India.
