What is CII For FY 2025-26: Why we need it for Income Tax Calculation
CII or Cost Inflation Index is considered to estimate the annual rise in an asset’s price due to inflation.
The process of Indexation determines that the cost of acquisition is adjusted against inflationary rise in the value of asset.
Although after 23th July 2024, all the Long Term Capital Gains will be taxed at flat rate of 12.5% without any indexation benefit. But we still need Indexation Rates for calculation of Income Tax Because:
There will be no clarity on long-term capital gain consumption if no Cost Inflation Index is available.
Normally, CBDT notifies about the CII around April-May each year. Last year it was notified on May 24, 2024 for FY 2024-25. However, this year it is still pending.
CII can be applied upon certain items, such as:
Cost Inflation Indexation cannot be applied to:

| 2024-25 | 363 |
Indexation for long-term capital assets helps in adjustment of the purchase price of the asset with the use of CII to account for inflation, hence giving reduced taxable capital gain. The formulas are listed below:
Indexed Cost of Asset Acquisition = (CII for the year of asset transfer x Cost of asset acquisition) / CII for the year of asset Purchase or year 2001-02, whichever comes later
Indexed Cost of Asset Improvement = (CII for the year of asset transfer x Cost of asset improvement) / CII for the year of asset improvement.
Reena purchased a house in FY 2001-02 for Rs 10 Lakh. She sells the same in FY 2023-24 on 25.07.2024 for Rs 40 Lakh. What will be the indexed cost of acquisition?
Solution:
Here, CII for year 2001-02 is 100; CII for year 2024-25 is 363. The indexed cost of acquisition = 10,00,000 * 363/100 = 36,30,000
Tax on Capital Gain @ 12.5% = Rs. 3,75,000
Tax on Capital Gain @ 20%
Capital Gain is 3,70,000 (40,00,000 – 36,30,000)
Tax = 74,000
Thus, the Maximum Capital gain tax will be limited to Rs. 74,000.
In the relation of CII, the “Base Year Concept” is used to calculate inflation adjusted values of assets to fulfill taxation objectives.
The index value is set to 100 for the base year, for calculation purposes( 2001-2002).
If an asset is aquired before 2001-2002, for tax purposes its aquisition cost is determined as the higher of two values:
