I am afraid that mere making payment through bank will entitle the assessee for claiming expenditure U/S 37(1) of the Income-Tax Act, 1961. It is the first and foremost liability of assessee to prove that the expenditure incurred by him qualifies the necessary test of section 37(1) of the Income-Tax Act, 1961. I find support in view from the case of CIT v.Calcutta Agency Ltd.(1951) 19 ITR 191 (SC), wherein the Hon’ble Supreme Court has held that the onus of providing necessary facts in order to avail the deduction under Section 37(1) is on the assessee. If, therefore, the assessee fails to establish the facts necessary to support his claim for deduction under Section 37(1), the claim for deduction of expenditure is not admissible. Further in the case of I.H. Sugar Factory & oil Mils (Pvt.) Ltd. Vs.CIT (1980) 125 ITR, 293 (SC) the Hon’ble Supreme Court has held that where an assesee claims a deduction the onus is on him to bring all material facts on record to substantiate his claim. The assesse did not furnish or produce any evidence as to what was the expenditure and why it was incurred. The assessee has thus failed to qualify the first test of Section 37(1) of the Income Tax Act, 1961. Mere claiming that the expenses were incurred through bank and evidence of payment is available with bank did not itself make the expenditure allowable in the case of assessee as something more is required to allow the deduction U/s 37(1) of the Income-Tax Act, 1961. The assessee vide reply on the issue has claimed to have requested tobank for providing copy of bills to him. In this regard, I would like to put on record that whenever an expenditure is incurred or nay item is purchased through credit card, there is always a bill which is signed by the credit holder and the showroom/shopkeeper given a copy thereof to the person/buyer. In the case of CIT v. Chandravilas Hotel (1987) 164 ITR 102 (Guj), it was held that mere production of vouchers in support of the claim for deduction of expenditure would not prove the claim made by the assessee. It is has duty to prove payment especially when the ITO doubts the genuineness therefore. It appears that the assessee does not want to product such bill before the assessing authority
