How Do Mergers and Demergers Affect Capital Gains?
Mergers and demergers can change the securities held by an investor without an ordinary market purchase or sale. Special tax rules can determine whether a transfer occurs and how the cost is allocated to the resulting securities.
Quick Answer
Do not treat securities received through a merger or demerger as ordinary purchases. Use the applicable corporate-action rules for acquisition date, cost allocation and subsequent capital-gain calculation.
Why Corporate Restructuring Matters
A merger or demerger can replace or distribute securities and alter the investor's holdings. The tax treatment depends on the statutory conditions of the restructuring.
Cost Allocation in a Demerger
Where cost must be allocated between original and resulting securities, the prescribed allocation method should be followed rather than using arbitrary market values.
Acquisition Date Can Carry Forward
Certain restructuring provisions can preserve or modify the original acquisition history for tax purposes.
Keep the Scheme and Corporate-Action Statement
Retain the merger or demerger scheme, broker communication, demat statement and any cost-allocation statement supplied by the company or intermediary.
Why This Matters for Future Sales
An incorrect cost or acquisition date can change both the capital gain and whether it is short-term or long-term when the resulting security is sold.
Important
Corporate-action tax treatment is highly fact-specific. The exact scheme and statutory conditions should be reviewed.
