Does the USA pay the most taxes on corporate income? No. Not even close.
I was just watching a clip in which a reporter tried to get Huckabee Sanders to admit Trump's claim that "America is the highest taxed nation in the world" is full of shit, and in which she just repeatedly said "highest corporate taxed nation, highest taxed nation, what's the difference?" (to which the quick reply should have been "you think the nation is just corporations? What about the people? You know, the voters who elected you and whom you claim to represent?", but never mind).
The top rate of tax on corporate income is currently a little higher in the USA than other OECD countries. But how many actually pay that on much of their profits? Not many. Because when you look at the percentage of GDP that OECD countries take in for this tax, you find, in the larger OECD countries (2015, except Australia) https://data.oecd.org/tax/tax-on-corporate-profits.htm :
Australia 4.69% (2014)
Japan 4.26%
Mexico 3.28%
South Korea 3.24%
Canada 3.13%
UK 2.45%
Spain 2.42%
USA 2.19%
France 2.11%
Italy 2.06%
Germany 1.74%
So the corporate tax structure in the USA is not bleeding companies dry (lowest corporate tax revenue in NAFTA, for instance). If anything, a high top rate should be a good incentive for them to not take profits now, but to reinvest income into the companies to ensure they have a healthy future.
