US Taxation of Multinational Enterprise: Part IV

So far, the discussion has ignored any foreign income taxes on Sue's surgeries. It now is time to look at this double taxation –- US income taxes plus foreign income taxes.

An obvious preliminary question is why do foreign income taxes, as compared to other costs of doing business overseas (like other foreign taxes), present a special case? The idea is that most costs are reflected in the prices at which goods and services are sold. Federal-level income taxes, however, are bone by the owners of the business. Thus, being required to pay US and foreign income taxes is double taxation. (The born-by-owners assumption is shaky, but further analysis is beyond this little post.)

So, there is double taxation, so what? The analysis here involves trade concerns more than tax policy analysis. A business' taxes should not depend upon where it does business (after adjusting for other local factors, such as malpractice liability in Sue's case), goes the analysis. This will interfere with free trade, so as to reduce world-wide well-being.

Which presents the question of which tax is the “extra” tax, the US tax or the foreign tax? The assumption underlying current international practice is that the source country (where Sue does her surgeries) gets first shot. Income is viewed as a thing that is more connected with the source than where it ends up. (As I mentioned in an earlier post, I do not view income as a thing, but what this means to this analysis I will not get to until later posts.)

Assuming that the US is to blink first, it needs a mechanism to do so. The US could just not tax foreign income that bears a foreign tax. This would unduly reward foreign income that bore only a low foreign tax. however. So, the US' mechanism is a dollar-for-dollar credit against US taxes for foreign taxes (subject to limits, which are the topic of tomorrow's post). If the foreign rate is the same as the US rate, the US gets no net tax. But, if the foreign tax is at a low rate, the US pockets the difference.

Note the US' altruism here: Historically, most multinational enterprises resided in the US. The US forbore collecting some taxes on these enterprises in the name of trade. Also, the Kennedy and Johnson Administrations embraced this regime because it discouraged tax competition between developing countries. (If the source developing country didn't impose a tax, the US would.) It was hoped that this would help such countries build needed infrastructure and institutions.

Tomorrow: more on the foreign tax credit.

    I think that the answer here is obvious, i.e. treat foreign taxation as a business expense. Our hypothetical Sue, who made $2 million in Europe but was taxed at 50%, should have her taxes based on the $1 million she has after foreign taxes have been assessed.

    Under the foreign tax credit and income tax treaties, there should be no double taxation. At least as long as the various tax authorities can agree on things like what is the appropriate intercompany pricing. Which is why the OECD Transfer Pricing Guidelines and their adherence to the simple concept of arm’s length is so important. I say simple as I see this is an economics concept based on the multinational’s facts. But yes I know some treat this is some overly complex regulatory blah, blah, blah, which tends to lead to all sorts of compliance nightmares for the companies who simply want to pay their fair share, while it sets up little games for the greedy to exploit. But when the likes of Daniel Mitchell cry double taxation, I suspect he knows better.

    If I read your recommendation correctly, she still is double taxed in a way. Let’s say she gets taxed at 50% in some land like Japan and then has her after-tax income taxed at 35% here. She ends up with $650,000 in after-tax income thereby paying an effective tax rate of 67.5%. OK, it’s not an 85% tax rate (Calpundit and Brad DeLong once had to correct Stephen Moore’s bad math on a similar score a while back). As I’m not a tax attorney, George may have to correct me here but I think you are suggesting a section 904 FTC treatment whereas a section 901 treatment would avoid the double taxation.
