Recomputation of income allows reassessment when capital gains are recharacterised and shifts limitation periods to financial year end. Amendments to section 155 change timing rules to reckon limitation and amendment periods from the end of the financial year in which an order or assessment was made, expand triggering orders to include those on applications by firms, associations or bodies, and insert a provision allowing the tax officer to re compute a transferor company's income where transfers later become chargeable as capital gains because the transferee treated the asset as stock in trade or a parent/holding ceased to hold all subsidiary shares, with amendment time limits applied from the end of the relevant previous year.
