You rightards are simply fucking nuts. There is no other explanation. No matter how many times this is explained, y'all still can't grasp it.
Foreign Tax Credit
If you paid or accrued foreign taxes to a foreign country or U.S. possession and are subject to U.S. tax on the same income, you may be able to take either a credit or an itemized deduction for those taxes.
Which is exactly what I demonstrated in my example. Why is that impossible for you to comprehend?
Here is my simplified example. Specifically how is this different from what you say?
So the company in Faunland pays Faunland's 20% corporate tax rate on their $100.00 of net profit leaving $80.00. They bring that $80.00 into the U.S. and pay a 38.9% corporate tax rate for the privilege of bringing that $80.00 into the states. That's an additional $31.12 in taxes. Eighty dollars minus $31.12 leaves them with $48.88 net profit after the money comes in the states?
Why would they do such a thing?
