The G7 agreement on a 15% minimum global tax rate: a significant step but a long road ahead

TAX alphabet with stack of coins & world map

On 5 June, 2021, the ministers of finance and central bank governors of the Groupe of Seven (G7), representing the main economies in the western world, expressed their commitment to work together “to build a safe, resilient and open global economic system.” The listed elements of this global cooperation include:

A race to the bottom

Taxation is a sensitive issue, in an almost borderless global economy where goods and services are easily sold from one country to another. This situation has created a “race to the bottom”, where some countries endeavour to attract private companies to be based in their jurisdiction in exchange for low taxation rates or other fiscal advantages, such as all sorts of exemptions. Currently, the regular basic corporate tax rate among the G7 countries is 19% in the U.K., 26% in the U.S., 27% in Canada, 28% in Italy, 30% in Japan and Germany and 32% in France. If one includes additional European countries, the spectrum is even wider:


In addition, there are further distortions if one considers such elements as “tax holidays”; different tax rates depending on whether the goods are exported or for the domestic markets; special treatments for copyrighted and intangible goods: how do you tax the viewing on a television set in France of a Netflix movie produced in the U.S. but distributed in Europe through a subsidiary in Ireland? We are confronted with a maze of regulations where some companies, helped by clever accountants and lawyers, “optimize” their taxes, which means they structure their businesses in order to pay as little as possible.

A significant step forward

Policymakers around the world have long been aware of this situation but disagreed until recently on the right approach to tackle the problem. In the absence of progress France had even started to tax large American companies that sold their products on its territory, often from a subsidiary based in Ireland. This of course created a negative reaction in the U.S. and retaliatory duties on French exports to America. No progress was made under the Trump administration because the different schemes under discussion would have penalized large American companies including the GAFAM (Google, Apple, Facebook, Amazon, Microsoft). The Biden administration, which has a more multilateral vision (and does not want to alienate Europe at a time it considers China as its main rival), took a significant step forward when the U.S. Treasury Secretary, Janet Yellen, proposed the creation of a taxation floor of 15% for large corporate multinationals. As stated in the G7 Finance Ministers Central Bank Governors communiqué: “We strongly support the efforts underway through the G20/OECD (Organisation for Economic Co-operation and Development, editor’s note) […] to address the tax challenges arising from globalisation and the digitalisation of the economy and to adopt a global minimum tax. We commit to reaching an equitable solution on the allocation of taxing rights, with market countries awarded taxing rights on at least 20% of profit exceeding a 10% margin for the largest and most profitable multinational enterprises. We will provide for appropriate coordination between the application of the new international tax rules and the removal of all Digital Services Taxes, and other relevant similar measures, on all companies. We also commit to a global minimum tax of at least 15% on a country by country basis.”

More hurdles ahead

Some key points from this historical but preliminary agreement should be kept in mind:

The next step in the implementation process, in parallel to ongoing “technical discussions” at the OECD, will be the G20 meeting scheduled in Rome on 30 and 31 October. It will then be possible to see if the framework accord reached in June could become an international binding agreement. Stay tuned…
