FAQ: How Does Indexation Work in Capital Gains Tax on Property?
Indexation adjusts your purchase price for inflation, reducing your taxable capital gain. Post-Budget 2024, the rules have changed. Here's the current framework.
Indexation is a mechanism that adjusts the purchase price of an asset for inflation, reducing the taxable capital gain. It was a significant tax benefit for real estate investors — but the rules changed dramatically with the Union Budget 2024.
How indexation worked (pre-Budget 2024):
For Long-Term Capital Gains (LTCG) on property held for more than 24 months, the purchase price was 'indexed' using the Cost Inflation Index (CII) published by the CBDT. The indexed (inflation-adjusted) purchase price was:
Indexed purchase price = Original purchase price × (CII of sale year / CII of purchase year)
The capital gain was then calculated as: Sale price − Indexed purchase price − Transfer expenses.
The LTCG was taxed at 20% (with indexation).
This significantly reduced the tax burden. For example, if you bought a property for ₹50 lakh in 2015 (CII 254) and sold it for ₹1.5 crore in 2024 (CII 363), the indexed purchase price would be ₹50 lakh × (363/254) = ₹71.4 lakh. The taxable gain would be ₹1.5 crore − ₹71.4 lakh = ₹78.6 lakh, taxed at 20% = ₹15.7 lakh. Without indexation, the gain would be ₹1 crore, taxed at ₹20 lakh.
The Budget 2024 change:
The Union Budget 2024 (effective 23 July 2024) made a significant change to LTCG taxation on real estate:
- The LTCG tax rate was reduced from 20% (with indexation) to 12.5% (without indexation).
- For properties purchased before 1 April 2001, the taxpayer can choose the fair market value as of 1 April 2001 as the purchase price (without indexation benefit on that FMV).
- For properties purchased on or after 1 April 2001 but before 23 July 2024, the taxpayer can choose between: (a) 12.5% without indexation, or (b) 20% with indexation — whichever is more beneficial. This 'grandfathering' provision protects existing investments.
- For properties purchased on or after 23 July 2024, the rate is 12.5% without indexation.
Practical impact: For most properties held for a long period (10+ years), the 20% with indexation option may still produce a lower tax than 12.5% without indexation, because the indexation benefit is substantial over long holding periods. For shorter holds (2–5 years), the 12.5% without indexation is typically better.
Our advice: always calculate both options for properties purchased before 23 July 2024 and choose the one that minimizes tax. Consult a tax professional for your specific situation.
You can also save LTCG tax entirely by reinvesting the gain in another residential property under Section 54, or in 54EC bonds (up to ₹50 lakh).
