COVID prompts new look at company taxes globally

The huge public deficits that have piled up as governments bail out their pandemic-hit economies are prompting the first rethink of a fourdecade decline in corporate tax rates worldwide.

Britain may be first to see the tide turn as soon as Wednesday when finance minister Rishi Sunak is widely expected to announce a small increase in corporate levies in his budget announcement to help pay for the hit from COVID-19. At 19%, Britain's corporate tax rate is among the lowest of the mostly wealthy 37 countries in the Organisation for Economic Cooperation and Development (OECD) group, whose average is 23%.

Countries around the world have been competing to lower the tax burden on companies in the decades following the free market Reagan and Thatcher revolutions of the 1980s against big government and in favour of business.

Since 2000 alone, when the OECD began collecting data, the average headline rate has fallen nine percentage points to record lows in many countries.

Moreover companies often pay less, sometimes much less, than the statutory tax rate due to each countries' various fiscal depreciation rules as well as other allowances and deductions.

"Raising tax rates on profit would go in the opposite direction to the trends over the last 35 years, driven by competition amongst countries to attract inward investment," said Michael P. Devereux with Oxford University Centre for Business Taxation in a note on the British move.

In Britain's case, Devereux cautioned against an increase as international competition on tax remains stiff even if the United States is considering an increase as well.
