Capital Gain Computation – How to Calculate Short Term and Long Term Capital Gains
Step-by-Step Computation of Capital Gains Under the Income Tax Act — Consideration, Cost, Indexation, and Deductions
Accurate computation of capital gain is the foundation of correct capital gain tax liability. The formula under Section 48 of the Income Tax Act is: Capital Gain = Full Value of Consideration – Cost of Acquisition – Cost of Improvement – Transfer Expenses. For Long Term Capital Gains on most assets, the cost of acquisition can be indexed using the Cost Inflation Index (CII) published by the Central Government — except for gains on equity shares and equity mutual funds (Sections 112A), and post-Finance Act 2024, for property sold after 23 July 2024 where the flat 12.5% rate without indexation applies (unless the transitional option is available).
The computation of capital gains involves several provisions that are frequently misunderstood or mis-applied — including the Section 50C stamp duty value rule, the FMV on 1 April 2001 option for pre-2001 assets, the grandfathering provisions for equity under Section 112A, and the treatment of bonus shares and rights issues. Our capital gain advisory service provides expert computation support — ensuring every gain is correctly calculated and every available deduction is claimed.
Our Capital Gain Computation Services
Full Value of Consideration
Determining the correct full value of consideration — actual sale price, or stamp duty value under Section 50C (whichever is higher for immovable property), or fair market value for other transfers.
Cost of Acquisition
Identifying the correct cost of acquisition — original purchase price, or FMV on 1 April 2001 (for assets acquired before that date), or written-down value for depreciable assets under Section 50.
Cost of Improvement
Computing the cost of improvement — capital expenditure incurred on the asset after acquisition that enhances its value — which can be deducted from the full value of consideration.
Indexed Cost Computation (CII)
Applying the Cost Inflation Index to compute the indexed cost of acquisition and indexed cost of improvement — reducing the taxable gain by adjusting historical costs for inflation (where indexation is available).
Transfer Expenses Deduction
Identifying and deducting eligible transfer expenses — brokerage, commission, stamp duty, legal fees, and other costs directly incurred in connection with the transfer of the asset.
Section 50C and Section 56(2)(x) Application
Advising on and applying the stamp duty value provisions under Section 50C (for the seller) and Section 56(2)(x) (for the buyer) in property transactions — to ensure both parties' computations are consistent and compliant.
