A draft plan by the government to increase state revenues, which is to be submitted to the Brussels Group on Thursday, includes increasing the luxury tax by 30 percent, imposing an accommodation levy on hotels with three stars or more, and the obligatory use of credit or debit cards for transactions of 70 euros or more on islands that have more than 3,000 inhabitants.

The latter measure will apply to the islands of Rhodes, Lesvos, Chios, Kos, Samos, Syros, Naxos, Santorini, Limnos, Kalymnos, Thasos, Myconos, Paros, Andros, Tinos, Icaria, Leros, Karpathos, Skiathos, Skopelos, Milos, Patmos (pictured) and Symi.
