Medals tax

As the 2012 London Olympics slowly comes to an end this weekend, the Americans still maintain their lead in medal winnings. As of Friday morning, the United States led with 90 medals comprised of 39 golds, 25 silvers and 26 bronze.

At this year's Olympics, the U.S. swimmers cleaned up with 31 medals while track and field is trying to catch up with its 24 medals. They may still have a chance.

And unless your completely tuned out, you'll know that swimmer Michael Phelps won six medals, leading the overall U.S. medal count.

But this doesn't just mean those Olympians are coming home as decorated, victorious athletes.

It means they're coming home to a pricey tax bill.

Turns out even Olympic achievements can't escape the U.S. Internal Revenue Service.
