The key words used in Section 40(a)(ia), according to us, are “on which tax is deductible at source under Chapter XVII –B”. If the question is “which expenses are sought to be disallowed?” The answer is bound to be “those expenses on which tax is deductible at source under Chapter XVII –B. Once this is realized nothing turns on the basis of the fact that the legislature used the word ‘payable’ and not ‘paid or credited’. Unless any amount is payable, it can neither be paid nor credited. If an amount has neither been paid nor credited, there can be no occasion for claiming any deduction.
The language used in the draft was unclear and susceptible to giving more than one meaning. By looking at the draft it could be said that the legislature wanted to treat the payments made or credited in favor of a contractor or sub-contractor differently than the payments on account of interest, commission or brokerage, fees for professional services or fees for technical services because the words “amounts credited or paid” were used only in relation to a contractor or sub-contractor. This differential treatment was not intended. Therefore, the legislature provided that the amounts, on which tax is deductible at source under Chapter XVII-B payable on account of interest, commission or brokerage, rent, royalty, fees for professional services or fees for technical services or to a contractor or sub-contractor shall not be deducted in computing the income of an assessee in case he has not deduced, or after deduction has not paid within the specified time. The language used by the legislature in the finally enacted law is clear and unambiguous whereas the language used in the bill was ambiguous.
