As always with tax, the concepts that we want to discuss are not discreet enough to translate into tax law. Revenue, profit, location and such are arbitrary decisions that can be made by an accountant. Does Apple makes its money in the US, where the company is headquartered and listed? Does it make it in China, where products are manufactured? Does it make it wherever people buy the stuff. Ireland, where the IP is "located." Since corporate tax is an income tax, it's taxed on profit... the not of revenue and expenses. Revenues and expenses are accrued everywhere. The entity booking them is arbitrary.
