Cost inflation index (CII) for FY 2023-24 to calculate capital gains

The Cost Inflation Index (CII) is a measure used by the Income Tax Department of India to account for inflation when calculating long-term capital gains on the sale of assets. It is a critical tool for taxpayers as it helps reduce the tax burden on capital gains by adjusting the asset's purchase price for inflation

Understanding the Cost Inflation Index is important for anyone dealing with assets that can appreciate over time. This measure allows you to accurately calculate your capital gains and the tax due on them, ensuring you don't pay more tax than necessary.

Adjusting the acquisition cost for inflation reduces the capital gains, thereby reducing the tax liability. This is particularly beneficial for assets held for a long period.
Cost Inflation Index for the Financial Year 2023-24

The CBDT (Central Board of Direct Taxes) releases the CII annually to help calculate the indexed acquisition cost for assets sold during the financial year. The Cost Inflation Index (CII) for the financial year 2023-24 is 348.

Cost Inflation Index: From 2001 to 2022

The base year for the Cost Inflation Index was changed from 1981 to 2001 by the CBDT. This means that the CII for the financial year 2001-02 is considered 100, and the indices for subsequent years are calculated relative to this base.

Here is the Cost Inflation Index (CII) from FY 2001-02 to FY 2023-24:

Financial Year	Cost Inflation Index (CII)
2001-02 (Base year)	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

This table provides a clear and concise overview of the Cost Inflation Index over the years, which is crucial for calculating the indexed acquisition cost and, consequently, the LTCG (long-term capital gains).

The Cost Inflation Index has steadily increased over the years, as we can see, reflecting the inflation rate. This consistent rise in the CII has helped taxpayers reduce their tax liability on long-term capital gains.

How is the Cost Inflation Index calculated?

The indexation cost is calculated as follows:

(Index for the year of sale/Index for the year of acquisition) x cost.

Suppose you purchased a property in 2001-02 for Rs10 lakhs 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 based on a specific base year. The CBDT last changed the base year from 1981 to 2001, which means that the CII for the financial year 2001-02 is considered 100, and the indices for subsequent years are calculated relative to this base.

The significance of the base year in CII

The base year is important in the Cost Inflation Index because it is the starting point for determining the CII for subsequent years. It allows for a standardised calculation of the indexed acquisition cost, ensuring that inflation's impact is accurately accounted for.

Changes in the base year can significantly impact the calculation of the Cost Inflation Index. When the base year was changed from 1981 to 2001 in India, the CII for 2001-02 was reset to 100. This change meant that the indexed acquisition cost for assets purchased before 2001 would be calculated differently, potentially leading to capital gains tax liability changes.

FAQs

1. What is the Cost Inflation Index for the Financial Year 2023-24?

The Cost Inflation Index for the Financial Year 2023-24 is determined to be 348. The CBDT or the Central Board of Direct Taxation notified of this through the Notification Number 21/2023 dated April 10, 2023.

2. What is the significance 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 reduces the capital gains on which taxes are levied, thereby reducing the overall tax liability.

3. What does CII mean for income tax?

The Cost Inflation Index essentially measures the yearly increase in the costs of various goods and services due to inflation. Therefore, the CII number for each financial year is utilised to determine the inflation-adjusted price of a given asset. Any capital gains chargeable as per the income tax rules in India are lowered with the indexation benefit availed.
