The Cost Inflation Index (CII) is a number published every year by the Income Tax Department to adjust the purchase price of an asset for inflation.
When calculating long-term capital gains on property, the purchase cost is increased using the CII to reflect inflation. This process is called indexation.
Indexation helps taxpayers reduce taxable capital gains, which ultimately lowers the tax payable on property sales.
For example, if you bought a property years ago, the inflation-adjusted cost will be much higher than the original purchase price, resulting in lower capital gains tax.
CII is used to calculate the Indexed Cost of Acquisition when a property qualifies as a long-term capital asset.
A property becomes long-term if it is held for more than 24 months before selling.
Benefits of using CII:
Adjusts property cost for inflation
Reduces taxable capital gains
Ensures fair tax calculation
Required when claiming long-term capital gains tax benefits
Below is the official Cost Inflation Index table used for capital gains calculations.

The base year for indexation is 2001-02, which means property purchased before 2001 can use Fair Market Value as of 1 April 2001 for capital gains calculation.
The formula used to calculate indexed cost is:
Indexed Cost = Purchase Cost ร (CII of Sale Year รท CII of Purchase Year)
This formula adjusts the purchase price to today’s inflation level.
Suppose:
Purchase price = โน10,00,000
Purchase year = 2005-06 (CII = 117)
Sale year = 2024-25 (CII = 363)
Indexed cost calculation:
Indexed Cost = 10,00,000 ร (363 รท 117)
Indexed Cost = โน31,02,564 (approx.)
If the property is sold for โน70,00,000, the capital gain would be:
70,00,000 โ 31,02,564 = โน38,97,436
Tax will apply only on the inflation-adjusted gain.
Indexation is available when:
Property is held more than 24 months
Capital gains are classified as long-term
Asset qualifies for long-term capital gains taxation
Indexation is not allowed for short-term capital gains.
If a property was purchased before April 1, 2001, the taxpayer can choose:
Actual purchase price, or
Fair Market Value (FMV) as on 1 April 2001
The higher value can be used to reduce capital gains tax.
Many taxpayers make mistakes while calculating capital gains:
Using incorrect financial year
Ignoring improvement cost indexation
Not applying indexation to renovation expenses
Using wrong CII values
These mistakes can lead to incorrect tax reporting and higher tax liability.

Property was purchased many years ago
Renovation costs need to be indexed
