Fact-checking correction

Okay, here's a better explanation of what's going on here, from farther down the factcheck.org page:

"If the company is actually that profitable, and depending on how the business is organized legally, Obama’s plan would indeed raise his federal income taxes, and Obama conceded as much during the exchange. As we’ve written before, small businesses commonly are organized in such a way that their owners file business taxes as individuals. So if Joe’s plumbing business earns more than $200,000 per year (or $250,000 if Joe is married and files tax returns jointly) then his taxes would indeed be higher under Obama's plan than under McCain's."
