IX. Mr. Gipit borrowed from Mr. Maunawain P100,000.00, payable in five (5) equal monthly installments. Before the first installment became due, Mr. Gipit rendered general cleaning services in the entire office building of Mr. Maunawain, and as compensation therefor, Mr. Maunawain cancelled the indebtedness of Mr. Gipit up to the amount of P75,000.00. Mr. Gipit claims that the cancellation of his indebtedness cannot be considered as gain on his part which must be subject to income tax, because according to him, he did not actually receive payment from Mr. Maunawain for the general cleaning services. Is Mr. Gipit correct? Explain. (4%)
