NEW YORK (CNNMoney.com) - Most voters are aware that Barack Obama wants to raise taxes on high-income taxpayers if he's elected president in November.
But what does the Democratic candidate mean by high-income? Who'd be affected and how? While the Obama campaign must still settle on more details about their plans, outlines are starting to emerge.
To start, Obama frequently cites $250,000 as the line between those who would be subject to higher taxes and those who wouldn't.
Indeed, under Obama's tax plan, married couples with at least $250,000 in gross income are likely to see their taxes go up if Obama is elected president.
But what about single filers? The line for them would likely be about $200,000, according to an Obama adviser.
Those groups could end up paying anywhere from several thousand dollars to tens of thousands of dollars more to Uncle Sam than they do now, according to estimates from the Tax Policy Center.
