LTCG on flat

Hi Assuming the gain accrues to you as individual and you are Resident (not NRI) in the year 2024-25

Your LTCG will be lower of the following:

1. 12.5% without indexation 
2. 20% with indexation

• For calculation of Gains and tax without indexation simply reduce sale price with cost of acqusition: INR 25 Lakh - INR 8 Lakhs = INR 17 Lakhs. Tax @ 12.5% is INR 2.125 Lakhs

• For Calculation of Gains and Tax with indexation it is as follows

Sale proceeds: INR 25 Lakhs

Indexed Cost of acqusition - 363/137 X 8 Lakhs = 21 Lakhs

Capital gains with Indexed cost: INR 25 Lakhs - INR 21 Lakhs = INR 4 Lakhs

Tax on above @ 20% -  INR 80,000

Option 2 is better for you.

But my CA is saying as I sold it on 17 th  March 2025 after July 2024 , indexation is not applicable, can I have any reference of it in the Income tax Act page no or document to support! Thanks and Regards 

Your CA is right with respect to calculation of capital gains however the tax incidence is limited to lower of both. See below citation where tax is lower of current provision or as per earlier provision.

Please refer to 2nd proviso to Sec 112(1)(ii)

"Provided further that in the case of transfer of a long-term capital asset, being land or building or both, which is acquired before the 23rd day of July, 2024, where the income-tax computed under item (B) exceeds the income-tax computed in accordance with the provisions of this Act, as they stood immediately before their amendment by the Finance (No. 2) Act, 2024, such excess shall be ignored;
