mine the amount of the chargeable income of such person and assess him accordingly, but such assessment shall not affect any liability otherwise incurred by such person by reason of his failure or neglect to deliver a return. (4) In making the assessment the Comptroller shall assess the income from each source and shall allow each de- duction and exemption to the nearest dollar. 59. (1) Where the Comptroller has reasonable grounds to believe that the main purpose or one of the main purposes for which any transaction was or transactions were effected (whether before or after the commencement of this Ordin- ance) was the avoidance or reduction of liability to tax for any year, he may, if he determines it to be just and reason- able, direct that such adjustments shall be made as respects liability to tax as he may deem appropriate so as to counteract the avoidance or reduction of liability to tax which would otherwise be effected by the transaction or transactions: Provided that this subsection shall not apply to any transaction the main purpose or one of the main purposes for which was to effect the succession by a resident company, in- corporated for that purpose, to any business carried on by an individual or partnership. (2) Without prejudice to the generality of the powers -conferred by subsection (1) of this section the powers con- ferred thereby extend- (a) to the charging with tax of persons who, but for the adjustments, would not be chargeable with any tax, or would not be chargeable to the same extent, and (b) to the charging of a greater amount of tax than would be chargeable but for the adjustments. 60. For the purpose of facilitating the assessment of the income of persons residing in the United Kingdom, the Ad- ministrator may appoint an agent in the United Kingdom who shall make enquiries on behalf of the Comptroller in respect of any such person as may apply to be dealt with through an agent, and shall ascertain and report to the Comptroller the amount of the chargeable income of such person in accordance with this Ordinance, and shall forward to the Comptroller the accounts and computation upon which his report is based. The Comptroller, on receipt of the report, shall enter the amount reported in the assessment list: Appointment of agent in the United King- dom. Transactions designed to avoid liability to tax.
