Capital gain rollover on sale of residential property: defers tax when proceeds invested in qualifying company shares. Capital gain from sale of long term residential property is deferred where the assessee invests net consideration in equity of an eligible company and the company utilises the proceeds to purchase prescribed new plant and machinery within one year; unutilised proceeds must be deposited in a specified account with proof on return, deposited and utilised amounts are deemed cost of the new asset, failure to utilise triggers taxation of the excess exempted gain upon expiry of the one year period, and transfers of the shares or new asset within five years revive the exempted gain as taxable in the year of such transfer.
