How to Calculate Capital Gain on Shares Received in a Merger?
A merger can replace shares of one company with shares of another without an ordinary market sale by the shareholder. Where the transaction qualifies for the relevant tax-neutral treatment, the cost and holding period of the new shares are carried forward under specific rules.
Quick Answer
For a qualifying amalgamation, the tax law can provide continuity of cost and holding period for shares received in exchange. The shareholder should preserve the merger ratio, original acquisition records and the new share allotment statement.
Is a Merger Automatically a Taxable Sale?
No. Certain qualifying amalgamations are specifically treated under the capital-gains provisions so that the exchange of shares can receive tax-neutral treatment, subject to statutory conditions.
What Happens to the Cost?
Where the relevant conditions are met, the cost of the original shares can carry over to the shares received in the amalgamation. The precise allocation should follow the applicable statutory provision and the scheme of amalgamation.
What Happens to the Holding Period?
The holding period of the original shares can be included when determining the holding period of shares received in a qualifying amalgamation. This can affect whether a later sale is short-term or long-term.
What Records Should Be Kept?
Keep the original purchase records, court/NCLT-approved scheme or company communication where relevant, merger ratio and new share allotment statement.
Practical Checklist
- Keep the original acquisition date and cost.
- Save the merger scheme and corporate-action statement.
- Record the exchange ratio.
- Do not treat every corporate restructuring as a qualifying amalgamation without checking the conditions.
