For property purchased in 1980, you are in the pre-July 23, 2024 category, which means you get to choose whichever option gives you a lower tax.
In the ITR-2 offline utility or the online portal, here is what to look for:
In Schedule CG under Long-Term Capital Gains (from land and building), there is a field for cost of acquisition and improvement WITH indexation and WITHOUT indexation. Enter both computations. The ITR utility should then auto-compute both tax amounts (20% with indexation, 12.5% without) and either let you choose, or default to the lower one.
If the portal is showing only the unindexed figure, it is possible that:
- The computation cell for indexed cost has not been filled in
- The FMV as on April 1, 2001 (for properties acquired before that date) has not been entered correctly - for a 1980 property, you need the FMV as on April 1, 2001 as your base cost, not the original 1980 purchase price
For a property bought in 1980, your cost of acquisition for indexation purposes is the HIGHER of actual cost or FMV on April 1, 2001. Get a valuation report for the 2001 date if you do not already have one.
This [Cost Inflation Index and indexation guide](https://taxgarden.in/blog/cost-inflation-index-cii-table-formula-indexation-capital-gains) has the full CII table from 2001 onwards and explains the indexed cost computation step by step.
