Indexation is one of the most powerful tools available to reduce your capital gains tax liability. By adjusting the purchase price of your investments for inflation, indexation can significantly lower your taxable gains and save you money. Understanding how indexation works is crucial for effective tax planning.
What is Indexation?
Indexation is a method of adjusting the purchase price of an asset for inflation to arrive at the indexed cost of acquisition. This helps reduce the taxable capital gains by accounting for the erosion in the value of money over time.
How Indexation Works
The Formula
Indexed Cost of Acquisition = Original Cost × (CII of Year of Sale / CII of Year of Purchase)
Components Explained
- Original Cost: The price you paid for the asset
- CII: Cost Inflation Index (published by CBDT)
- Year of Sale: Financial year when you sold the asset
- Year of Purchase: Financial year when you bought the asset
Cost Inflation Index (CII)
The CII is published annually by the Central Board of Direct Taxes (CBDT) and reflects the inflation rate for that year.
Recent CII Values
| Financial Year | CII |
|---|---|
| 2023-24 | 348 |
| 2022-23 | 331 |
| 2021-22 | 317 |

Example Calculations
Example 1: Debt Mutual Fund
Purchase: ₹1,00,000 in FY 2019-20
Sale: ₹1,50,000 in FY 2023-24
Indexed Cost = ₹1,00,000 × (348/289) = ₹1,20,415
Taxable Gain = ₹1,50,000 - ₹1,20,415 = ₹29,585
Without indexation: ₹1,50,000 - ₹1,00,000 = ₹50,000
Tax Savings: ₹20,415 (40.8% reduction in taxable gains)
Example 2: Real Estate
Purchase: ₹50,00,000 in FY 2015-16
Sale: ₹80,00,000 in FY 2023-24
Indexed Cost = ₹50,00,000 × (348/254) = ₹68,50,394
Taxable Gain = ₹80,00,000 - ₹68,50,394 = ₹11,49,606
Without indexation: ₹80,00,000 - ₹50,00,000 = ₹30,00,000
Tax Savings: ₹18,50,394 (61.7% reduction in taxable gains)
