* The Finance (No. 2) Act, 2024 removed the indexation benefit and introduced a uniform tax rate of 12.5% on long-term capital gains. As per the amendment, no indexation benefit is allowed while computing capital gain from long-term capital assets transferred on or after 23-07-2024. However, the Government has introduced a grandfathering provision. This provision allows resident individuals and resident HUFs to still apply indexation on land or building acquired before 23-07-2024 and pay tax at the old rate of 20% if the tax under the new law (i.e., tax calculated at 12.5% without indexation benefit) results in a higher amount.

However, there are some cases where benefit of indexation is not available, which are as under:
