Group of 20 finance ministers agreed on Saturday to compile common rules to close loopholes used by global tech giants such as Facebook to reduce their corporate taxes, a copy of the bloc’s draft communique obtained by Reuters showed.Facebook, Google, Amazon, and other large technology firms face criticism for cutting their tax bills by booking profits in low-tax countries regardless of the location of the end customer. Such practices are seen by many as unfair. The new rules would mean higher tax burdens for large multi-national firms but would also make it harder for countries such as Ireland to attract foreign direct investment with the promise of ultra-low corporate tax rates.“We welcome the recent progress on addressing the tax challenges arising from digitization and endorse the ambitious program that consists of a two-pillar approach,” the draft communique said. “We will redouble our efforts for a consensus-based solution with a final report by 2020.” Britain and France have been among the most vocal proponents of proposals to tax big tech companies that focus on making it more difficult to shift profits to low-tax jurisdictions, and to introduce a minimum corporate tax.This has put the two countries at loggerheads with the US, which has expressed concern that US Internet companies are being unfairly targeted in a broad push to update the global corporate tax code. “The United States has significant concerns with the two corporate taxes proposed by France and the UK,” US Treasury Secretary Steven Mnuchin said on Saturday at a two-day meeting of G20 finance ministers in the Japanese city of Fukuoka.“It sounds like we have a strong consensus” about the goals of tax reform, Mnuchin later said. “So now we need to just take the consensus across here and deal with technicalities of how we turn this into an agreement.”Mnuchin spoke at a panel on global taxation at the G20 after the French and British finance ministers voiced sympathy with his concerns that new tax rules do not discriminate against particular firms.Big Internet companies say they follow tax rules but have paid little tax in Europe, typically by channelling sales via countries such as Ireland and Luxembourg, which have light-touch tax regimes.
