S. 45: Capital gains – Redevelopment -On redevelopment of a building, the redeveloped flat received in lieu of the original flat is a continuation of the existing capital asset and not a new independent capital asset- The period of holding is to be reckoned from the date on which rights in the original property/redevelopment crystallised and not from the date of the Permanent Alternate Accommodation Agreement- Consequently, gain on sale of the redeveloped flat is assessable as long-term capital gain and eligible for indexation and exemption under sections 54/54F.
