Tax

Currently my age is 56 yrs and have my investments with unrealised capital gains in both short and long term equity shares of stable big companies and paying towards a home loan (only one house) with annual interest repayment above Rs 2 lakhs and Section 80C savings Rs 1.5 lakhs. Other than house I have only equity and bank SB interest income of around Rs 20000 and no other income. Currently equity LTCG is taxed @ 10% on gains in excess of Rs 1 lakh per year and STCG is taxed flat @ 15%. I understand one can adjust equity short & long term capital gains (or tax payable on them) with basic limit of Rs 2.5 lakhs also. As I see in ITR 2 online in ITD portal the computation is a bit round about, on which I don’t have clarity. So this year I wish to book some STCG/ LTCG on equity to avail the same but not clear on how much of the gains in each category I can book for nil tax. Does this figure works out to Rs 2.5 lakh basic exemption + Home loan interest Rs 2 lakhs + 80C benefits Rs 1.5 lakhs . So Total gains I can book would be Rs 2.5L+Rs 2L+Rs 1.5L = Rs 6 lakhs if it is purely STCG and another Rs 1 lakh of gains i.e., Rs 7 lakhs if it is LTCG only. (Of course SB interest would be taxable beyond Rs 10000 availing 80TTA, which can be ignored). Thanks in advance for your kind clarifications
