Second floor built in 2020 is a cost of improvement:
• Construction of a second floor on an existing house (June 2020) is a capital improvement. Its cost is added to the cost of acquisition when computing capital gains on sale (Sec 48, 55(1)(b)).
• Holding period: the second floor is a separate improvement. If sold together, the entire house (original plus improvement) is generally treated as one asset with the original holding period. Tribunals treat improvements as part of the same asset.
• Indexation (if opting, sale after 23 July 2024 for a resident individual, property acquired before 23 July 2024): index the original cost from its year, and the improvement cost from 2020-21.
• Keep bills, payment proofs and municipal approvals for the construction.
