One of the dumbest laws around involves how the United States taxes profits earned by American companies operating in foreign countries. If the money is earned overseas and kept there, the United States often doesn't tax it at all. Yet if that cash is brought back -- "repatriated" in official terms -- it usually gets taxed pretty heavily. As a result, even American companies have strong incentives to invest overseas and neglect their operations at home.

In essence, it means the cash that could otherwise be put to use in the United States is staying away. The better jobs, stronger economy, and improving lifestyles all that money could provide? It's certainly doing that -- for the foreign countries where it's staying.

To understand the effect of this insanity, look no further than the one-time repatriation tax break that existed as part of the American Jobs Creation Act of 2004. All told, somewhere in the neighborhood of $300 billion found its way back into the U.S. economy, thanks to that one-time tax break that let the money come home cheaply.

That's a lot of cash -- money that just scratches the surface of what America is losing thanks to stupid tax laws. To give you an idea of just how big an impact tax laws have on the choices businesses make, this chart shows how much money some firms brought home when given the chance:

Company

Amount Repatriated

Hewlett-Packard (NYSE:HPQ)

$14.5 billion

Johnson & Johnson (NYSE:JNJ)

$11 billion

IBM (NYSE:IBM)

$9.5 billion

Schering-Plough (NYSE:SGP)

$9.4 billion

DuPont (NYSE:DD)

$9.4 billion

Eli Lilly (NYSE:LLY)

$8 billion

PepsiCo (NYSE:PEP)

$7.5 billion



Profit from it
Unfortunately, the law that allowed all that money to come back to the United States cheaply has expired. This means that the future earnings those companies make overseas will once again be reinvested abroad. That's more cash drained from the American economy and handed over to the rest of the world.

The real beneficiaries of this idiocy, however, aren't the American companies that are essentially forced to keep their cash overseas. They would have earned the money anyway. The folks who really make out are the foreign businesses that get the expansion capital created by all this mandatory overseas reinvestment. For them, it's new money that they otherwise wouldn't have seen.

Dumb tax laws like this one are a key reason why the rest of the world is gaining at America's expense. Fortunately, you can do something about it. Just because America suffers doesn't mean you have to suffer along with it.

You can profit from this phenomenon by investing in the foreign firms that benefit from America's outrageous tax laws.
