I find the whole concept that there is such a thing as an American company to be pretty laughable. The idea that we should be tax their profits not only is bad economics, it is flat out immoral.
Let’s take a classic "American " company like General Motors. Last year GM sold million cars.
4 Million cars in China
3 Million car in the US
3 Million cars in the Rest of the world
There #3 country is Brazll where they sold 343,000 cars.
First of all, explain how most of their profits are made in America when 70% of the cars they sold (and manufactured) are overseas? The reality is the vast majority of Fortune 500 companies have the majority of their sales overseas. Generally speaking profit margins are higher on overseas operations, because of the combination of the higher corporate tax rate in the US and the US market is typically the most competitive.
In the case of GM in a good year they make $.05 per dollar of revenue, so there isn’t a ton of profit to tax.
So if we tax their profits in Brazil which has ~30% corporate tax rate, one of the direct consequences is that there is less money for the Brazilian government to tax. The means less money for the poor of Brazil, where poverty is whole new level compared to US poverty. Wealth inequality within the US is nothing compared to wealth inequality in the world.
The problem with old US corporate rate is that difference between 38% and Ireland 18% absolutely encourages creative accounting. While it is facile to say “well should just crack down on the abuser”, in order to do that you have to write laws. The corporations are always going to be hiring smarter accountant and lawyers than the government. So if you have a team of SW engineers in Ireland and the US working on a project, who is to say that right allocation for the Irish portion is 25%, 50% or 75%. We live in a world where a handful of guys at Snapchat can get acquired for $4 billion.
I’ve been ambivalent about economic of lowering the corporate tax rate. On one hand, the Democrats argument that corporation already had a ton of cash so the likely impact of lowering the tax was simply going to be an increase share buybacks and raising of the dividend was very strong. On the other hand, the classic economic argument that lowering the US corporate tax rates, increases the profitability of US venture, which will encourage new investment.
One thing is for sure is that a 21% rate is going eliminate a lot jobs in the tax department for big corporations. These are smart people so I’m sure they can find more productive jobs.
It is still early, and there is a lot of posturing. But certainly, the Apple announcement is good news. I just hate that Trump will take credit for it. This is mostly Paul Ryan’s tax plan if anybody deserves credit or blame it is Paul.
