An NRI has to pay capital gain tax on the profit made by selling a property. If a property is held for 3 years or less following the actual possession, then short-term capital gain tax is paid. The gain will be included in the total income & normal slab rates will be applied. However, if the property is held for more than 3 years, then long-term tax rates will be applicable. This will include 20% tax rates plus applicable cess.
