If you're interested, you can estimate the profit on revenue in all countries relatively easily by multiplying the country revenue by the overall margin.
These numbers tell you how much profit _Apple USA_ made in those countries.
Say Apple USA typically makes $300 on an $800 iphone sold in Germany. Where should this $300 be taxed?
To me, it seems perfectly reasonable that most of it is taxed in the US, since the iPhone was invented, developed, engineered in the US and ultimately the business and product was created in the US.
And indeed this is how international corporation tax works by decades of rules on transfer pricing and how corporations are allowed to assign expenses and value along international supply chains.
If you demanded that Apple pay full German corporation on ALL of the profits made by Apple in Germany, then you are claiming that the innovation, engineering and design that occurred in the US contributed ZERO value to the iPhone.
And even if you did that, it would not change Apple's tax liability (much) as it would just mean shifting corporation tax rights from the US to Germany.
It's not strange that all the European calls for shifting the right to tax corporates from the countries where they do the most work/create the value to other countries only seem to apply to "internet giants" but not "car giants" or "aviation giants" or "food giants" which whould result in European countries having to give up large amounts of corporation tax income to other countries.
