Yes it is Capital gain tax....

If a property is sold within three years of buying it, it is treated as a short-term capital gain. This is added to the total income and taxed according to the slab rate.

If a property is sold after three years from the date of purchase, the profit is treated as a long-term capital gain and is taxed at 20% after indexation.
