According (Google Translate) to the newspaper Repubblica.it, Apple was fined R $ 1.3 billion (318 million) for transferring money to Ireland to avoid paying taxes in Italy.
According to the newspaper, the investigation was carried out by the Italian tax administration and, after refusing to pay the amount for a long time, Apple agreed with everything. It is worth noting that, according to the investigation, the company avoided paying taxes on about R $ 3.5 billion (818 million) between 2008 and 2013 precisely because it transferred the money to Ireland (where the rates are lower).
In the United States, Apple is being accused precisely of carrying out legal maneuvers to pay less taxes (amount of money that the company has outside the country) Tim Cook has even gone to Washington to discuss the matter.
The agreement now made in Italy sets a precedent. We will see if this same investigation will be opened now in governments / countries that somehow feel injured.
