Hi,

You will be liable to pay LTCG tax@20% plus applicable surcharge and cess.
To calculate the long-term capital gains tax payable, the following formula is to be used:
Long-term capital gain = full value of consideration received or accruing – (indexed cost of acquisition + indexed cost of improvement + cost of transfer), where:
Indexed cost of acquisition = cost of acquisition x cost inflation index of the year of transfer/cost inflation index of the year of acquisition.
Indexed cost of improvement = cost of improvement x cost inflation index of the year of transfer/cost inflation index of the year of improvement.
