Global Minimum Corporate Tax Rate

Context: US has proposed for a global corporate minimum tax rate and is working with G20 countries to agree on a global minimum, which it said could help end a “30-year race to the bottom on corporate tax rates.


  • Major economies are aiming to discourage multinational companies from shifting profits – and tax revenues – to low-tax countries regardless of where their sales are made.
  • Increasingly, income from intangible sources such as drug patents, software and royalties on intellectual property has migrated to these jurisdictions, allowing companies to avoid paying higher taxes in their traditional home countries.
  • With a broadly agreed global minimum tax, the US administration hopes to reduce such tax base erosion without putting American firms at a financial disadvantage, allowing them to compete on innovation, infrastructure and other attributes.
  • The Trump administration took a first stab at capturing revenues lost to tax havens with a U.S. corporate offshore minimum tax in 2017. The “Global Intangible Low-Taxed Income,” or GILTI, tax rate was only 10.5% – half the domestic corporate tax rate.


  • The Paris-based OECD has been coordinating tax negotiations among 140 countries for years on two major efforts: setting rules for taxing cross-border digital services and curbing tax base erosion, with a global corporate minimum tax part of the latter.
  • The OECD and G20 countries aim to reach consensus on both fronts by mid-year, but the talks on a global corporate minimum are technically simpler and politically less contentious.
  • Since the talks are consensus based, countries are expected to go along with agreement no matter how unpalatable it may be for some low tax countries.
  • The minimum tax is expected to make up the bulk of the $50 billion-$80 billion in extra corporate tax that the OECD estimates companies will end up paying globally if deals on both efforts are enacted.


  • The global minimum tax rate would apply to companies’ overseas profits. Therefore, if countries agree on a global minimum, governments could still set whatever local corporate tax rate they want.
  • But if companies pay lower rates in a particular country, their home governments could “top-up” their taxes to the agreed minimum rate, eliminating the advantage of shifting profits to a tax haven.
  • US has said it wants to deny exemptions for taxes paid to countries that don’t agree to a minimum rate
  • The OECD said last month that governments broadly agreed already on the basic design of the minimum tax although the rate remains to be agreed. International tax experts say that is the thorniest issue.
  • Other items still to be negotiated include whether industries like investment funds and real estate investment trusts should be covered, when to apply the new rate and ensuring it is compatible with the 2017 U.S. tax reforms aimed at deterring tax-base erosion.


  • The Biden administration wants to raise the U.S. corporate tax rate to 28%, so it has proposed a global minimum of 21% – double the rate on the current GILTI tax. It also wants the minimum to apply to U.S. companies no matter where the taxable income is earned.
  • That proposal is far above the 12.5% minimum tax that had previously been discussed in OECD talks – a level that happens to match Ireland’s corporate tax rate.
  • The US is eyeing to get $2.5 trillion in 15 years by raising corporate tax rates from 21% currently to 28%. However, doing so in isolation will put the US at a disadvantage vis-à-vis tax havens. Therefore, it wants everyone to follow its lead.

Not Good for Low Income/Middle Income Countries

  • Multinationals are a source of foreign direct investment. These corporations help to generate demand with efficient utilisation of resources and create employment in low-income countries.
  • Nations have used their freedom to set corporation tax rates as a way to attract such businesses. Smaller countries such as Ireland, the Netherlands and Singapore have attracted footloose businesses by offering low corporate tax rates.
  • The global minimum tax rate will finish off every opportunity for such countries whose only weapon to attract these companies is lower taxes. 
  • In a world where there are income inequalities across geographies, a minimum global corporation tax rate could crowd out investment opportunities.
  • A lower tax rate is a tool for India to alternatively push economic activity. If the proposal comes into effect, India may experience a longer economic hangover than other developed nations with less ability to offer mega stimulus packages.
  • The policy itself puts a question on globalisation as it will be beneficial only for the US to become a monopoly.
