conclusion - let us assume our asset be rural agricultural land and we got the long term gains from the same where - we can claim deduction under 54B as we got gains from rural agricultural land which requires to be the same. - we can claim deduction under 54EC as it says long term capital gains can be saved by investing in specific bonds where our gains are long term (rural agricultural land transfer). - we can claim deduction 54F as it says gains shall be other than from residential property where our asset is not the same.
so we can claim three deductions at once but rarely one would such thing.
- Land which was sold had been used for agricultural purpose for atleast 2 years 'immediately preceding' to the date of transfer. - there shall not be any intension to earn profit by the seller through transfer of the same.
