Does the new health care law impose a 3.8 percent tax on profits from selling your home?

No, with very few exceptions. The first $250,000 in profit from the sale of a personal residence won’t be taxed, or the first $500,000 in the case of a married couple. The tax falls on relatively few — those with high incomes from other sources.

Only a tiny percentage of home sellers will pay the tax. First of all, only those with incomes over $200,000 a year ($250,000 for married couples filing jointly) will be subject to it. And even for those who have such high incomes, the tax still won’t apply to the first $250,000 on profits from the sale of a personal residence — or to the first $500,000 in the case of a married couple selling their home.

The sort of people who would have to pay the tax might include, for example:

• A single executive making $210,000 a year who sells his $300,000 ski condo for a $50,000 profit. His tax on the sale of that vacation home would amount to $1,900, in addition to the capital gains tax he would have paid anyway.
• An "empty nester" couple with combined income of over $250,000 a year who sell their $1 million primary residence to move to smaller quarters. If they cleared $600,000 on the sale, they would be taxed on $100,000 of the profit (the amount over the half-million-dollar exclusion). Their health care tax on the sale would amount to $3,800 over and above the usual capital gains levy.

However, a typical home sale would not incur any tax. In March, for example, half of all existing homes sold for $170,700 or less, according to the National Association of Realtors. Obviously, none of those sales could possibly generate a $250,000 profit, and so none would be subject to the tax.
Thus, for the vast majority, the 3.8 percent tax won’t apply. The Tax Foundation, in a report released April 15, said the new tax on investment income (including real estate) "will hit approximately the top-earning two percent of families" when it takes effect in 2013.

The Internal Revenue Service says that to qualify for the $250,000/$500,000 exclusion, a seller must have owned the home and lived there as the seller’s "main home" for at least two years out of the five years prior to the sale.
