un exhausted Basic exemption first from LTCG or STCG

as stt paid short term capital gains are taxed at 15% u/s 111A unlike long term capital gains from sale of imm property which is taxable at 20% u/s 112.,u shd use ur unutilised basic exemption limit first against long term capital gains and balance towards short term gains

there is no specific requirement under income tax act abt the priority in which unutilised basic exemption limit can be utilised..accordingly assessee can use his unutilised basic exemption limit as he likes

S 112 of the Income Tax Act provides for adding LTCG to the normal income in case normal income is below taxable income.  111A also has a similar provision.  Rohit's suggestion is correct.
