The grandfathering choice, explained
Budget 2024 replaced indexed property taxation with a flat 12.5% rate — but gave people who'd already bought property before the change a way to avoid an unfair retroactive hit:
Indexation adjusts your purchase price for inflation using the Cost Inflation Index (CII), which shrinks your taxable gain — valuable for property held many years through high inflation. For property bought closer to the sale date, the inflation adjustment is small, so the flat 12.5% rate usually wins instead. This calculator computes both and shows you which wins for your specific numbers, rather than assuming one is always better.
Property bought on or after 23 July 2024 doesn't get this choice at all — it's 12.5% without indexation, full stop.
Frequently asked questions
You can use the Fair Market Value as on 1 April 2001 as your cost of acquisition instead of the actual purchase price, with indexation calculated from FY 2001-02 (CII 100). This calculator's earliest year is 2001-02 for that reason — enter the 1 April 2001 FMV as your purchase value if your property predates it.
