The Income Tax Department releases a statistic known as the Cost Inflation Index (CII) for each financial year. The figure determines an asset's indexed cost or inflation-adjusted price.
When an item purchased a few years ago is sold during a specific financial year, the indexed cost of the asset is required. Long-term capital gains have been created due to the sale of an asset; the CII number will be useful in determining the long-term capital gains subject to taxation.
The Central Board of Direct Taxes (CBDT) announced the CII for FY 2021–22 as 317 last year on June 15, 2021. This CII figure determines the number of long-term capital gains or losses accumulated if an individual sold an asset in FY 2021–2022.
It is an index that is used to estimate the nominal increase in an asset's value brought on by inflation. Concerning the cost inflation index, there are two aspects that people have to be aware of.
First off, only those assets where inflation-adjusted (indexation benefit) is permitted will be used to determine inflation-adjusted cost using this number. The sum beyond Rs 1 lakh per fiscal year is taxed at a flat rate of 10% without an indexation advantage; hence the CII value cannot be utilized to calculate LTCG/LTCL on equity mutual funds.
Furthermore, this CII number will be necessary to determine LTCG for assets where indexation is permitted prior to the imposition of LTCG tax in FY 2021–2021. You will pay the taxes on these proceeds when you file your income tax returns (ITR) for FY 2021–2022. (AY 2022-23).
The Cost Inflation Index (CII) determines the annual inflation-related rise in the cost of goods and assets. Assets with a long lifespan are subject to the CII. For the welfare of taxpayers, this leads to increased acquisition costs and lower profits and taxes. For the advantage of taxpayers, this benefit is applied to long-term capital investments, which leads to greater purchase costs, lower profits, and lower taxes.
The initial year, 1981, serves as the basis year for the cost inflation index. The index value for the year 1981 is 100. Assess the index of all succeeding years to the base year in order to calculate the inflation rate rise in percentage terms. The value of the acquisition will be higher than the "real cost or Fair Market Value (FMV)" if the asset was acquired before the base year. The determined purchase price is then adjusted for the indexation advantage. The FMV is determined using the valuation report of a registered valuer.
The base year at the moment is 2001.
The purchase price will be greater than the actual cost or FMV as of April 1, 2001, if the capital asset is acquired before that date.
The Central Board of Direct Taxes (CBDT) calculated the cost inflation index and announced in the Official Gazette.
The cost Inflation Index is equal to 75% of the average annual increase in the Consumer Price Index* (Urban).
The sum of income tax levied on long-term capital gains from the sale of the asset can be drastically decreased for taxpayers thanks to indexation. Indexation is not a possibility, though, for gains or losses on short-term capital investments. This perk is not available to non-resident Indians.
Taxpayers must take into account the following requirements in order to receive the indexation advantage for long-term capital gains:
The cost of acquisition (purchase price) of the capital asset is now the indexed cost of acquisition as and when the indexation advantage is applied to it. In a similar way, it becomes the indexed cost of the improvement when it pertains to the cost of the improvement.
Indexed Cost of Acquisition is equal to [Cost of Indexation (CII) for the year of transfer (sale)* Cost of Acquisition]/CII for either the year 2001-2002 or the first year the asset was retained by the assessee, whichever comes later.
(CII of Year of Sale / CII of Year of Purchase) * Cost of Acquisition Indexed Cost of Improvement is calculated as follows: [Cost of acquisition (CII) for the year of transfer (sale)* Cost of improvement]/CII for the year the asset was improved.
The following instance explains the idea of indexation as it relates to long-term capital assets:
Instance 1:
Ella spent Rs. 700000 on vehicles on July 15, 2016, and sold them on May 1, 2020.
The indexed cost of acquisition will be as a result.
For the purchasing year F.Y. 2015–16, the Cost Inflation Index (CII) was 254, and
CII for the sales year, F.Y. 2020–21, equals 301.
As a result, the indexed cost of acquisition is equal to Rs. 8,29,527.56(approx) (700000*301/254).
The following considerations about CII in India should be made:
Financial Year | Capital Gain Index |
2001-02 | 100 |
2002-03 | 105 |
2003-04 | 109 |
2004-05 | 113 |
2005-06 | 117 |
2006-07 | 122 |
2007-08 | 129 |
2008-09 | 137 |
2009-10 | 148 |
2010-11 | 167 |
2011-12 | 184 |
2012-13 | 200 |
2013-14 | 220 |
2014-15 | 240 |
2015-16 | 254 |
2016-17 | 264 |
2017-18 | 272 |
2018-19 | 280 |
2019-20 | 289 |
2020-21 | 301 |
2021-22 | 317 |
2022-23 | 331 |
2023-24 | 348 |

Gains in the capital are produced by capital assets. Since the cost price is historical, developing an indexed cost enables the taxpayer to consider inflation. Therefore, one can minimize the capital gains number to lower the tax payment by using CII to assess the asset's true cost.
For the period 2022–2023, the cost inflation index is 331
If an asset is purchased before the base year of CII or 2001, the asset purchase price may be equal to the higher of the asset's fair market value or its actual cost as of the base year's first day. The indexation advantage can then be utilized after the price has been established.
