Capital Gains Indexation Rules
Capital gains tax can significantly reduce your profit when you sell property, mutual funds, or other long-term assets. Indexation is one of the most powerful tools available to Indian taxpayers to lower this tax legally. With multiple changes in recent years including the removal of indexation for debt mutual funds and ongoing debates around real estate taxation, many taxpayers are searching for clarity. This guide explains capital gains indexation rules in India for 2025 in simple terms, using current laws applicable for AY 2025-26 (FY 2024-25).
Capital Gains Indexation Rules Explained in Simple Terms
Indexation adjusts the purchase cost of an asset for inflation using the Cost Inflation Index (CII) notified by the Income Tax Department. This higher adjusted cost reduces your taxable Long Term Capital Gains (LTCG).
Bottom line: Indexation reduces tax by accounting for inflation over the holding period.
Under the Income Tax Act, 1961:
- Indexation applies only to long-term capital assets
- It uses the notified CII of the year of purchase and year of sale
- It is not available for all asset classes
The legal basis for indexation comes from Section 48 of the Income Tax Act.

Cost Inflation Index 2024-25 for Capital Gains India
The Cost Inflation Index (CII) is notified every year by the Central Board of Direct Taxes (CBDT).
CII for FY 2024-25 is 363
This index is used for calculating LTCG for AY 2025-26.
Recent CIIs for reference:
- FY 2022-23: 331
- FY 2023-24: 348
- FY 2024-25: 363

Long Term Capital Gains Indexation Explained India
An asset becomes long-term when held beyond a specified period.
Holding Period for LTCG in India
- Immovable property (land or building): More than 24 months
- Listed equity shares and equity mutual funds: More than 12 months
- Other assets (gold, unlisted shares): More than 36 months
Indexation benefit is available only where LTCG is taxed under normal provisions and not at a special flat rate.
Capital Gains Tax Calculation with Indexation India
The indexed cost is calculated using this formula:
Indexed Cost of Acquisition = Original Cost × (CII of Sale Year ÷ CII of Purchase Year)
Practical Example
- Property purchased in FY 2010-11 for ₹50,00,000
- Sold in FY 2024-25 for ₹1,50,00,000
- CII for FY 2010-11: 167
- CII for FY 2024-25: 363
Indexed cost = ₹50,00,000 × (363 ÷ 167) = ₹1,08,68,263
Taxable LTCG = ₹1,50,00,000 – ₹1,08,68,263 = ₹41,31,737
Tax payable at 20 percent (plus cess).
Indexation Benefit on Property Sale India
For Indian taxpayers, real estate remains the most common asset where indexation delivers large tax savings.
Key points:
- LTCG on property is taxed at 20 percent with indexation
- Stamp duty value may apply under Section 50C
- Improvement costs can also be indexed
Indexed Cost of Improvement

Capital Gains on Real Estate After Indexation India
After indexation:
- Tax burden reduces substantially for long-held properties
- Inflation adjustment often cuts taxable gains by 40–60 percent over long periods
You can further reduce tax by:
- Claiming exemption under Section 54 (residential property reinvestment)
- Claiming exemption under Section 54EC (capital gains bonds up to ₹50,00,000)
Indexation Rules for Inherited Property India
Inherited or gifted property follows special indexation rules.
Key rule:
Indexation starts from the year the previous owner acquired the asset, not the year of inheritance.
Example:
- Father bought property in FY 2005-06
- Son inherited it in FY 2020-21
- Son sells it in FY 2024-25
Indexation applies from FY 2005-06, giving a major tax advantage.

Indexation Benefit Removed for Debt Mutual Funds India
One of the biggest tax changes in recent years affects debt mutual funds.
What Changed?
From 1 April 2023:
- Debt mutual funds with less than 35 percent equity exposure
- Are taxed as short-term capital gains
- Indexation benefit is removed, regardless of holding period
This change applies to investments made on or after 1 April 2023.
Grandfathering Rules
- Investments made before 1 April 2023 still get indexation if held long-term

Grandfathering Rules for Capital Gains Indexation India
Grandfathering protects old investments from new tax rules.
Applicable cases:
- Debt mutual funds purchased before 1 April 2023
- Certain bond and debenture investments under old regimes
Not applicable to:
- New debt mutual fund investments
- Equity shares (separate grandfathering applied only for gains up to 31 January 2018)
LTCG Indexation vs Non Indexation Tax India
In some cases, taxpayers can choose between:
- 20 percent tax with indexation
- 10 percent tax without indexation
This option applies mainly to:
- Listed securities
- Certain bonds and debentures
Which Is Better?
- Long holding period + high inflation: Indexation wins
- Short holding period + high appreciation: Non-indexation may be better
Always compute both options before filing your return.
