Italy expects to take until the end of the year for an initial assessment of Facebook parent Meta in a tax case that could land the US company with a bill of around 870 million euros ($925 million) and prove a test case for the tech sector. Although a modest sum for a company that brought in more than $32 billion in revenue last year, the case could have much wider ramifications for the industry as it hinges on the way that Meta provides access to services such as Facebook and Instagram.
