Long-term capital gains tax for companies requires separate higher-rate taxation on land/building gains and on other long-term gains. Substituted section 115 requires that where a company's total income includes long-term capital gains, tax is the aggregate of: (i) tax on long-term capital gains computed by applying higher rate to gains from buildings, lands or rights therein and a lower rate to other long-term gains; and (ii) the tax which would be chargeable if the company's total income were reduced by those long-term capital gains.
