Tax on foreign-currency-purchased mutual fund units taxed under special rates and deduction limits for offshore funds. Income of an overseas financial organisation from units purchased in foreign currency or long term capital gains on their transfer is taxed by aggregating: ten per cent on income from such units; a special rate on long term capital gains (ten per cent before the amendment date and twelve and one half per cent thereafter); and the tax on remaining income after excluding those components. If such income alone comprises the gross total income, specified deductions and a proviso to capital gains computation are disallowed; if it is only part, the gross total income is reduced by that income for Chapter VI A deductions.
