Portugal’s Tax and Customs Authority (AT) carried out several searches in the districts of Aveiro and Porto today, as part of a tax fraud case that allegedly damaged the State by €2.5 million. In a statement, AT said that as part of a criminal case being dealt with by the Department of Investigation and Prosecution (DIAP) in Santa Maria da Feira, five non-domicile search warrants were served, and two people have since been made ‘official suspects’. Under suspicion are companies soliciting telecommunications contracts from a foreign multinational and energy supply from a Portuguese company, which have allegedly built a scheme to simulate operations, using false invoicing.
