(1) Deductible expenditures incurred by a person in deriving foreign-source income chargeable to tax under a head of income shall be deductible only against that income.
(2) If the total deductible expenditures referred to in sub-section (1) exceed the total foreign source income for a tax year chargeable to tax under a head of income (hereinafter referred to as a “foreign loss”), the foreign loss shall be carried forward to the following tax year and set off against the foreign source income chargeable to tax under that head in that year, and so on, but no foreign loss shall be carried forward to more than six tax years immediately succeeding the tax year for which the loss was computed.
(3) Where a taxpayer has a foreign loss carried forward for more than one tax year, the loss for the earliest year shall be set off first.
(4) Section 67 shall apply for the purposes of this section on the basis that —
