The New Health Care Law and Taxes on Home Sales

Plus, there are other criteria before the tax applies: The home sale must produce a profit, so any home that is "underwater" is exempt. Ranches and farms are also exempt, as are properties used for business.

If you don't meet all criteria, you don't pay the tax.

The money from this tax will help support the Medicare program.

The tax was designed to affect a very small minority of homeowners. Only about 4 percent of American households earn over $200,000 a year, according to the latest statistics from the U.S. Census, and 2 percent have incomes $250,000 and higher. So, at most, 4 percent of American households will face the health care tax. In addition, half of all existing homes sold for $178,600 or less, according to the latest figures from the National Association of Realtors. So most home sales do not produce a profit that could trigger the tax.

"We have been fighting the same rumor over and over that certain political groups have put out about this 'outrageous' tax," says Lucien Salvant, a spokesman for the association, which represents 1.1 million Realtors. "The vast middle class of folks are not going to be hit by this tax when they put their house up for sale."
