¹[103A. (1) Notwithstanding anything contained in this Ordinance, where a non-resident person carries on the business of operation of aircraft, as the owner or charterer thereof (hereinafter in this section referred to as the principal), and any aircraft owned or chartered by him calls on any airport in Bangladesh, the aggregate of the receipts arising from the carriage of passengers, livestock, mail or goods loaded at the said airport into that aircraft shall be deemed to be income received in Bangladesh by the principal from the said business chargeable to tax under the head “Income from business or profession” and tax thereon shall be charged at the rate of three per cent of such income. (2) The principal or an agent authorised by him in this behalf shall prepare and furnish to the Deputy Commissioner of Taxes, within forty-five days from the last day of each quarter of every financial year, that is to say, the thirtieth day of September, the thirty-first day of December, the thirty-first day of March and the thirtieth day of June, respectively, a return in respect of each quarter as aforesaid showing- (a) the amount paid or payable whether in or out of Bangladesh to the principal, or to any person on his behalf, on account of the carriage of passengers, livestock, mail or goods loaded at the said airport; and (b) the amount received, or deemed to be received, in Bangladesh by, or on behalf of, the principal on account of the carriage of passengers, livestock, mail or goods at any airport outside Bangladesh. (3) On receipt of the return, the Deputy Commissioner of Taxes may, after calling for such particulars, accounts or documents, as he may require, determine the aggregate of the amounts referred to in sub-section (2) and charge tax as laid down in sub-section (1). (4) Where the principal fails to pay the tax payable under sub-section (1), for more than three months, the Commissioner of Taxes may issue to the authority by whom clearance may be granted to that aircraft a certificate containing the name of the principal and the amount of tax payable by him; and on receipt of such certificate, the said authority shall refuse clearance from any airport in Bangladesh to any aircraft owned or chartered by such person until the tax payable has been paid. (5) Nothing contained in this Ordinance shall be so construed as to allow any expense against the aggregate amount of receipts as determined under sub-section (3). (6) The tax paid under this section shall be deemed to be the final discharge of the tax liability of the assessee under this Ordinance, and the assessee shall not be required to file the return of total income under section 75 nor shall he be entitled to claim any refund or adjustment on the basis of such return.]
