Hi,
while calculating the capital gain at the time of selling the above said property.
cost of land & cost of acquisition of house will be considered as long term
while indexation of reconstruction of house would be done from the year of completion. if you keep it for period of two years from its completion , it will also fall under long term. otherwise it is short term.
as per Sri. K. Rajendra , Bangalore vs Assessee on 7 August, 2012,
below are extract from the case..
Remodel : to model again, to make over, to rebuild (b) Renovation : to make new The aforesaid dictionary meaning of the two terms, even if the same are used separately, meaning to construct or to construct something new in case the two words are read jointly, then the same will mean nothing but "building something new."
6. In legal parlance also, the said terms have been interpreted to have the same in "The Law Lexicon" by Justice Y.V. Chandrachud, second Edn. (Report) 2001.
"Construction and reconstruction are interchangeable terms and the only difference is that the phrase "construction" will be used where a new building is put up where none existed before, but reconstruction will apply to a building which is rebuilt in the place of an existing building, but in both these cases there would' be construction. Sadha Singh S. Mulla Singh vs District Board, AIR 1962 Pun 204 (East Punjab Urban Rent Restriction Act 3 of 1949 s. 3)"
Thus, from whatever angle the case is examined, 'remodel and renovation' amounts to construction of house and this is more so in the present case where an altogether new portion has been built after razing old construction, to the ground.
I would suggest to keep the house for period of two years after getting completion certificate to avail long term benefits.
here is the link of the above case law
