Dear Sir,
Your capital gain would be aggregate of monetary consideration plus market value of the flat which you are getting. However, you will get the proportionate exemption for the amount of flat under section 54F. This is subject to the fact that you satisfy all the following conditions:
The exemption is allowed only if the new property is a residential house.
The exemption is allowed, If you did not have any more than one residential property before the new house.
The purchase of new residential house should be within one year before or 2 years after.
The construction of residential house should be completed within 3 years.
The residential house should be in India.
The assessee should sell or transfer the new house within three years of its purchase or construction. If it happens, the capital gains exemption would be withdrawn similar to the section 54.
Calculation of Exemption Under Section 54F :
The total capital gain would be exempted if 100% sale proceeds is invested in the residential property.
If full capital gains is not invested (i.e. your case), exemption shall be allowed proportionately. The exempted amount would be calculated according to the following formula.
Capital Gain X Amount Invested/Net Sale Consideration
Please feel free to call/revert in case of any doubts
Thanks and Regards
