Computation of profit on transfer of business capital asset distinguishes block-level and single-asset formulas for taxable profit. Taxable profit for a business capital asset within a scheduled block is A minus B and C: amount accrued or received (including scrap) less opening written down value of the block and the actual cost of assets acquired during the year; a negative result is treated as nil. For assets outside such a block, taxable profit is amount accrued or received (including scrap) less the asset's actual cost.
