Capital gains tax is levied on profits arising from the transfer of a capital asset. For gains to be taxed under capital gains, there must be a capital asset that is transferred, resulting in profits. Any profits exempted under sections 54-54G are not taxed. Capital assets include all property except certain exceptions like stock-in-trade. Short term capital gains arise from assets held for 36 months or less, while long term gains are for assets held longer. Indexation of cost is used to arrive at capital gains for long term assets by factoring inflation. Profits are taxed differently based on whether the gain is short term or long term.
