Also let us take an example different from th above query. (do not mix both)
Mr. A purchased a House property on loan. he repaid the installments in 10 years. with principal repayment each year being rs 1.5 lacs. Also paid interest amounting rs. 3 lacs. adequate deduction u/s 24b was also taken for interest paid.
Now in 10 th year, he sold the house property for rs. 32 lacs.
To compute the cap gains-
Sale Consideration 32 lacs
(-) COA (15 + 3)* Indexation benefit 20 lacs (assume 20 lacs is the amount after indexation)
Hence Cap gains = 12 lacs
So in this case assesee first took benefit of 15 lacs in 80C, then he took the benefit of same 15 lacs in the 10th year, in the form of deduction as COA. same with interest amount.
This is whats normally done. So..is'int it also a DOUBLE BENEFIT..... which should not be allowed.......
