Expenditure on transfer must be wholly and exclusively related to capital asset transfers to qualify as deductible. Expenditure incurred wholly and exclusively in connection with the transfer of a capital asset is deductible from the full value of consideration; timing is immaterial so long as the expense relates exclusively to the transfer. Examples include brokerage or commission and stamp costs. Such expenses, once deducted for capital gains computation, cannot be claimed again under any other head of income.
