Section 44AE of the Income-tax Act provides a special scheme for computing taxable income from the business of plying, hiring or leasing goods carriages. The provision is intended to simplify the determination of business income for small taxpayers by allowing income to be calculated on a presumptive basis instead of requiring detailed maintenance of accounts and calculation of actual profit. The scheme applies to an assessee who owns not more than ten goods carriages at any time during the previous year and is engaged in the business of plying, hiring or leasing such goods carriages. A goods carriage generally means a motor vehicle used for carrying goods. The important condition is that the assessee should not own more than ten goods carriages at any time during the previous year. If the number exceeds ten, the presumptive provisions of Section 44AE are not applicable. Under Section 44AE, income is determined with reference to the number and type of goods carriage and the period for which each vehicle was owned by the assessee
