Taxation Aspects of Demerger in India


The Income-tax Act, 1961 provides the tax reliefs to the demerged company, the shareholders of the demerged company, who are issued and allotted shares in the resulting company in the exchange for the shares held by them in the demerged company and the resulting company which emerges as a result of a demerger.


 1.     Capital Gain Tax not attracted: As per section 47 (vib) of the Income Tax Act, the transfer of any capital asset by the demerged company to the resulting company will not be regarded as transfer for the purpose of capital gain.

2.  Tax relief to Foreign Demerged Company: As per section 47 (vic), where a foreign company holds any shares in an Indian company and transfer the same to resulting company in the course of demerger, such transfer will not be regarded as “Transfer” for the purpose of capital gain, if following conditions are satisfied:

§   75% of the shareholders of demerged foreign company continue to remain shareholders of the resulting foreign company.

§   Capital gains tax is not attracted on the demerged foreign company in the country of its incorporation and S. 391 to S. 394 of the Companies Act will not be applicable.


1. Dividend:  Section 2(22) has been amended by inserting a new clause (v) to provide that no dividend income shall arise in the hands of shareholders of demerged company on demerger.

2. Capital Gains: As per section 47 (vid), any transfer or issue of shares by the resulting company to the shareholders of the demerged company, in scheme of demerger, is not regarded as “Transfer” for the purpose of Capital Gains.

In case, the shareholders transfer these shares subsequent to the demerger, the cost of such shares will be calculated as under:

Cost of acquisition of Shares in resulting  Company


Cost of acquisition of Shares held by assessee in the demerged company


Net book value of assets transferred in demerger.

Net Worth of the demerged company immediately before demerger

We can illustrate and substantiate the concept by means of an example of Reliance Industries Limited which is the Demerged Company and the new companies of which shares were issued are the Resulting Companies.

 In this case, Reliance Industries Ltd. (RIL) has transferred four of its businesses to four separate companies. The telecom leg has been transferred to Reliance Communication Ventures Ltd, the coal based energy system has been transferred to Reliance Energy Ventures Ltd, the financial services leg has been transferred to Reliance Capital Ventures Ltd.  And lastly the gas based energy business has been transferred to Reliance Natural Resources Ltd.

Consequence of the demerger:

The existing shareholders of RIL got one share each in the Resulting Companies for every share that they held in RIL.

Tax impact of the above:

As per the Income Tax Act, a transaction of demerger, per se, has no tax implications on the shareholders. In other words, when the shareholders of RIL are allotted the new shares in each of the four companies, there would be absolutely no tax implication whatsoever.

The tax implication will only arise when either the shares of RIL or the shares of the new Resulting Companies are sold.

Tax implications when shares are sold:

When the shares of any of the companies are sold, it would give rise to capital gains tax liability. The three issues that arise are:

§   Whether the new shares (in the Resulting Companies) are long-term assets or short-term.

§   Indexation of the capital gains.

§   Cost of acquisition of the various shares after the demerger transaction

a)  To find out whether or not shares in the Resulting Companies are long-term or not, the holding period of the RIL shares will be included in the period of holding of the new shares.

b)  The indexation will start from the date of allotment of the new shares and not from the date of acquisition of RIL. Relevance of indexation is only for working out the capital gain amount if the same has to be set-off against capital loss. However, as explained further on, for most shareholders, there will be no need of this.

c)  To calculate capital gains when the shares are sold, a vital piece of information is the cost of acquisition. Your original cost of acquisition of RIL shares will change now on account of the demerger. Plus there will be a new cost accorded to the new shares of the Resulting Companies. The Income Tax Act specifies a complicated formula that takes into account the proportion of the net worth of RIL vis a vis the book value of the businesses transferred to arrive at the new costs of acquisition.

The net results of the above calculations are summarized in the following table: 

Name of Company

% of Cost of Acquisition of RIL Shares

Reliance Industries Limited


Reliance Communication Ventures Limited


Reliance Energy Ventures Limited


Reliance Capital Ventures Limited


Reliance Natural Resources  Limited



 What the above table indicates is the proportion in which your original cost of acquisition of RIL shares will be apportioned to the new shares.

It Can be understood by an example:

e.g. Say, Rakesh had purchased 100 shares of RIL for Rs. 534 on January 10th 2005. Consequently, his total cost of acquisition would be Rs. 53,400. Now, post the demerger, his new costs would as in the table here.

RIL (52% of Rs. 53,400)

Rs. 27,768

RCVL (38.7% of Rs. 53,400)

Rs. 20,666

REVL (7.3% of Rs. 53,400)

Rs.  3,898

RCVL (1.3% of Rs. 53,400)

Rs.    694

RNRL (0.7% of Rs. 53,400)

Rs.    374


Rs. 53,400

For the per share cost, the above values be divided by the number of shares. For example, Rakesh's new cost of acquisition of RIL post demerger would be Rs. 27,768 divided by 100 which work out to Rs. 277.68.

Now lets say he sells the all the above shares on January 15th. As explained earlier, since he has bought the shares on Jan 10th last year, 12 months have elapsed and hence the RIL shares will be long-term capital assets. Similarly, for the new shares, the period of holding RIL will be taken into account, thereby making these too long-term assets.     

Therefore, since long-term capital gains are tax-free, if any or all of the above shares are sold on a recognized stock exchange, there would be absolutely no tax payable by Rakesh in the entire process.


1.   Amortisation of expenditure in case of amalgamation or demerger (Sec. 35DD): Expenses by an Indian company incurred after 1-4-1999 for amalgamation or demerger of an undertaking, shall be amortized @ 20% each year starting from the year in which amalgamation or demerger takes place.

2.  Depreciation shall be apportioned between the demerged company and the resulting company in the ratio of number of days for which the assets were used by them.

3.  The accumulated losses and unabsorbed depreciation in a demerger shall be allowed to be carried forward by the resulting company

4.  Benefits available for demerger are also extended to authorities or boards set up by Central or State Government.
