About this tool
Indexation adjusts the cost of acquisition of a long-term capital asset for inflation, reducing your taxable capital gain. Base year: FY 2001-02 (CII = 100). Indexed cost = Original cost × (CII of sale year ÷ CII of purchase year). Applicable to: PROPERTY purchased before 23-Jul-2024 (taxpayer may elect 20% with indexation OR 12.5% without indexation); GOLD purchased before 23-Jul-2024 (similar election); UNLISTED SHARES. NOT applicable to: post 23-Jul-2024 property/gold purchases; debt MF (all debt MF post 1-Apr-2023 lost indexation); listed equity (never had indexation). Choose whichever produces lower tax for old assets.
