Online poker giant PokerStars has been accused of a €300m tax fraud by Italy’s financial police, charges the company has vehemently rejected.

On Wednesday, Italy’s Guardia di Finanza accused PokerStars of using subsidiaries of Stars’ parent company the Rational Group to “willfully erode” its Italian tax obligations for the period spanning 2009 to 2014.

The fiscal cops said the Halfords Media Italy subsidiary had used transfer pricing methods to shift Italy-generated income to other Rational subsidiaries in more tax-friendly jurisdictions in the Isle of Man and Malta, while keeping its Italian costs in the country, thereby reducing the amount it owed the Italian taxman.

The Italian police have said the managing director of PokerStars’ Italian operations would be charged with tax evasion for “the implementation of this complex criminal design.”
