sec 24 (b)

the full amount of interest in the year of possession is allowed as in this case interest for the period april 2008 to jan 2009 will be also added to the amount of current interest and not in the pre construction period

ya it should not be taken as pre-construction period interest.

only interest upto 31-3-2008 should be taken as pre-construction period interest.

interest from 1/4/08-31/12/08 should be claimed for A.Y 2009-10

 yes, it should be taken as current year interest and not as pre-construction period interest.

So, both Trinath and Ashish Gupta are right................
