Cost of Improvement with Indexation in Real Estate Capital Gains (India)

With Budget 2024 changing how indexation works for real estate, understanding the latest rules for AY 2025-26 (FY 2024-25) is now critical for property owners, investors, and tax professionals.
This detailed guide explains cost of improvement with indexation under income tax in India, how the Cost Inflation Index (CII) applies to property improvements, and how the new capital gains rules for real estate in 2024 impact your tax liability.

BLUF: Cost of improvement with indexation allows you to inflate the actual cost of property improvements using the Cost Inflation Index, reducing your taxable long-term capital gains.
Under Section 48 of the Income Tax Act, 1961, capital gains on property are computed as:
Sale Consideration
minus Indexed Cost of Acquisition
minus Indexed Cost of Improvement
minus Transfer Expenses
Meaning of Cost of Improvement
Cost of improvement refers to capital expenses incurred to:
- Add value to the property, or
- Increase its useful life
Examples include:
- Construction of an additional floor
- Structural renovations
- Permanent fixtures like flooring replacement
Routine repairs and maintenance do not qualify.
Section 48: Cost of Improvement Indexation Explained
Section 48 cost of improvement indexation in India allows adjustment of improvement costs for inflation using the Cost Inflation Index (CII) notified annually by CBDT.
Indexed Cost of Improvement Formula
