Cost Inflation Index (CII) in India: Understanding its Role in Taxation
he Cost Inflation Index (CII) adjusts asset purchase prices for inflation, reducing long-term capital gains tax liability in India. It applies to real estate, mutual funds, and other assets
The Cost Inflation Index (CII) is a crucial tool in the Indian taxation system used to adjust the purchase price of capital assets for inflation. It helps taxpayers determine the indexed cost of acquisition to calculate long-term capital gains (LTCG) on the sale of assets like real estate, mutual funds, and stocks (not subject to Securities Transaction Tax). The index is notified annually by the Central Board of Direct Taxes (CBDT) under the Income Tax Act, 1961.
Purpose of Cost Inflation Index
Inflation erodes the real value of money over time. The CII ensures that taxpayers are taxed only on real gains rather than nominal gains. It helps in:
- Reducing tax liability – By adjusting for inflation, the indexed cost of acquisition increases, thereby reducing taxable capital gains.
- Reflecting fair asset valuation – It provides a more accurate reflection of asset appreciation over time.
- Encouraging long-term investment – The indexation benefit is available for long-term assets, making investments in certain asset classes more attractive.
Cost Inflation Index Table
The base year for CII calculation was shifted from 1981-82 to 2001-02 in Budget 2017. The index for financial years since then is as follows:

Formula for Indexation
To calculate the indexed cost of acquisition, the following formula is used:
Indexed Cost of Acquisition = (Cost of Acquisition) × (CII of Year of Sale / CII of Year of Purchase or Base Year 2001-02, whichever is later)
Example Calculation
Suppose an investor purchased a property in 2010-11 for Rs 10,00,000 and sold it in 2023-24. The indexed cost will be:
Indexed Cost = (10,00,000) × (348 / 167) = Rs 20,83,832
If the property is sold for Rs 35,00,000, the taxable LTCG is:
LTCG = Selling Price - Indexed Cost
LTCG = 35,00,000 - 20,83,832 = Rs 14,16,168
Without indexation, the gain would be Rs 25,00,000, leading to a higher tax liability.
Assets Eligible for Indexation
- Real estate – Land and buildings held for over 2 years.
- Debt mutual funds and bonds – Before April 1, 2023 (indexation benefit removed thereafter).
- Other capital assets – Gold, unlisted shares, jewellery, etc.
Conclusion
The Cost Inflation Index plays a significant role in determining capital gains taxation in India. It provides relief to taxpayers by adjusting for inflation, ensuring fair taxation. Understanding and applying CII correctly can help investors minimize tax liabilities and make informed investment decisions.
