A comprehensive guide on how the Cost Inflation Index impacts your capital gains.
The Cost Inflation Index (CII) serves as a metric used by the Income Tax Department of India to factor in inflation when determining long-term capital gains from asset sales. This index was essential for taxpayers, as it helped reduce the tax liability on capital gains by modifying the purchase price of assets to reflect inflationary changes. Nevertheless, a declaration made during Finance Minister Nirmala Sitharaman’s Budget 2024 address made it redundant.
Presenting her seventh consecutive Union Budget, Sitharaman announced changes to the capital gains tax rates. The tax rate on short-term capital gains for ‘specified’ assets has been raised to 20 percent, up from the previous rate of 15 percent. She further stated that all other financial and non-financial assets will be subject to the relevant tax rates. Additionally, she adjusted the long-term capital gains tax rates, increasing them from 10 percent to 12.5 percent for all asset categories, while also raising the exemption limit for capital gains on certain listed financial assets from Rs1 lakh to Rs 1.25 lakh annually.

Sitharaman also announced that the indexation benefit for property sales would be removed. This decision indicates that individuals selling their properties will no longer have the ability to adjust their purchase price in accordance with inflation. Consequently, this change will lead to an increase in their capital gains and a corresponding rise in their tax obligations, rendering the cost inflation index obsolete.
Previously, the cost inflation index played a crucial role for those involved with appreciating assets. It facilitated the precise calculation of capital gains and the associated tax liabilities, ensuring that taxpayers would not incur excessive tax payments.
The cost Inflation Index used to be important for anyone dealing with assets that can appreciate over time. It allowed one to calculate his/her capital gains and the tax due on him/her accurately, ensuring the individual doesn’t pay more tax than necessary.
Cost Inflation Index for the Financial Year 2024-25
The CBDT (Central Board of Direct Taxes) used to release the CII on an annual basis to help in determining the indexed acquisition cost for assets disposed of within the financial year. For the financial year 2024-25, the CII was set at 363. However, due to recent amendments, CBDT will no longer release the CII.
Cost Inflation Index historical data: From 2001 to 2024
The CBDT has revised the base year for the Cost Inflation Index from 1981 to 2001. Consequently, the Cost Inflation Index for the financial year 2001-02 is set at 100, with the indices for the following years being determined in relation to this new base year.
Here is the Cost Inflation Index (CII) from FY 2024-25 to FY 2001-02:
| Financial Year | Cost Inflation Index (CII) |
| 2024-25 | 363 |
| 2023-24 | 348 |
| 2022-23 | 331 |
| 2021-22 | 317 |
| 2020-21 | 301 |
| 2019-20 | 289 |
| 2018-19 | 280 |
| 2017-18 | 272 |
| 2016-17 | 264 |
| 2015-16 | 254 |
| 2014-15 | 240 |
| 2013-14 | 220 |
| 2012-13 | 200 |
| 2011-12 | 184 |
| 2010-11 | 167 |
| 2009-10 | 148 |
| 2008-09 | 137 |
| 2007-08 | 129 |
| 2006-07 | 122 |
| 2005-06 | 117 |
| 2004-05 | 113 |
| 2003-04 | 109 |
| 2002-03 | 105 |
| 2001-02 (Base year) | 100 |
The table above offers a clear and concise overview of the Cost Inflation Index across many years, which is essential for determining the indexed acquisition cost and, in turn, the long-term capital gains (LTCG). The Cost Inflation Index has shown a consistent upward trend over the years, indicative of the prevailing inflation rate. This ongoing increase in the CII has enabled taxpayers to mitigate their tax obligations related to long-term capital gains.
How to calculate Cost Inflation Index?
The indexation cost is calculated using the formula:
(Index for the year of sale/Index for the year of acquisition) x cost.
Suppose you purchased a property in 2001-02 for Rs 10 lakh and sold it in 2022-23. The CII for 2001-02 is 100, and for 2022-23, it’s 317. Using the formula, the indexed cost of acquisition would be:
317 / 100 * 10,00,000 = Rs. 31,70,000
What is the base year in CII?
In India, the Cost Inflation Index calculates the indices for different years using a base year. The CBDT recently changed the base year from 1981 to 2001. Thus the CII for the financial year 2001-02 is set at 100, with the indices for the following years calculated in relation to this base year.
Changes in the base year can have a substantial effect on the computation of the Cost Inflation Index. In India, when the base year was shifted from 1981 to 2001, the CII for the fiscal year 2001-02 was established at 100. This adjustment implied that the indexed acquisition cost for assets acquired prior to 2001 would be determined in a different manner, which could result in alterations to capital gains tax obligations.
FAQs
What is the importance of the Cost Inflation Index in taxation?
The Cost Inflation Index is important for taxation purposes. It is used to calculate the indexed cost of acquisition, which is the purchase price of an asset adjusted for inflation. This adjustment is crucial as it lowers the capital gains subject to taxation, thereby reducing the overall tax liability.
Can CII be used to reduce tax?
The Cost Inflation Index (CII) can be used to significantly decrease the income tax imposed on capital gains derived from the sale of long-term capital assets.
What is the Cost Inflation Index for the Financial Year 2023-24?
The Cost Inflation Index for the Financial Year 2023-24 has been set at 348. This information was officially communicated by the Central Board of Direct Taxation (CBDT) via Notification Number 21/2023, issued on April 10, 2023.
What are the exemptions and deductions on capital gains?
The Income Tax Act offers various exemptions that can lower the tax liability on capital gains.
- Section 54: Tax on long-term capital gains from the sale of a residential property can be avoided if the proceeds are reinvested in another residential property.
- Section 54EC: A tax exemption on long-term capital gains is available if the proceeds are invested in designated bonds within six months following the sale.
- Section 54F: Long-term capital gains from the sale of any asset, excluding a residential house, can be exempted if the entire sale proceeds are invested in a residential property.
- Section 54B: An exemption can be claimed if agricultural land, used for farming for a minimum of two years prior to the sale, is sold. To qualify, the capital gains must be reinvested in another agricultural land within two years.
- Section 54D: If land or buildings utilised for industrial purposes are compulsorily acquired, an exemption can be claimed. This requires reinvestment of the proceeds in new industrial assets within three years of the sale.
- Section 54EE: Tax on capital gains from long-term assets can be avoided by investing the gains in units of a specified fund within six months of the sale, with a maximum investment limit of ₹50 lakh per financial year.
- Section 54G: An exemption is available if an industrial undertaking is relocated from an urban area to a non-urban area. The gains must be reinvested in specified assets such as land, buildings, or machinery within three years.
- Section 54GA: Similar to Section 54G, an exemption on capital gains can be claimed when relocating an industrial undertaking to a Special Economic Zone (SEZ). To qualify for this exemption, the reinvestment must take place in eligible assets within a three-year period.
