For purposes of section 24C(2) of the Income Tax Act 58 of 1962, income must be received or accrued 'in terms of' the same contract that creates the obligations for which future expenditure will be incurred. The phrase 'in terms of' ('ingevolge') in section 24C(2) bears its narrow meaning - requiring a direct and immediate connection between the income and the contract. Income is not earned 'in terms of' a contract merely because that contract enables or facilitates the earning of income. The actual source of income must be identified. In a franchise arrangement, income is earned from individual patron contracts (sales transactions), not from the franchise agreement itself, even though the franchise agreement enables the franchisee to operate the business. Section 24C does not allow for different income-earning and obligation-imposing contracts; both must be the same contract.
