Indexation
Tax term
Indexation adjusts an asset's purchase price upward for inflation, reducing the taxable capital gain on certain long-term assets.
It uses the government's Cost Inflation Index. Note that from July 2024 indexation was removed for most assets, with a lower flat 12.5% LTCG rate applied instead (with limited grandfathering for older property).
