No deduction for investment income of non-resident Indians; Chapter VI-A relief applies only after excluding such income. No deduction is allowed for any expenditure or allowance in computing investment income of a non-resident Indian. If gross total income consists only of investment income or long-term capital gains (or both), Chapter VI-A deductions do not apply and certain capital gains provisos are inapplicable. If gross total income includes such incomes, that amount is excluded and Chapter VI-A deductions are permitted as if the gross total income were the reduced amount.
