Does New Health Care Law Contain a 3.8% Home Sales Tax?

The question and debate surrounding whether the Health Care Law actually contains a 3.8% Home Sale tax has been renewed over the past few weeks as the new Congressional session has begun. Not only has our friends from Keeping Current Matters dusted off a blog post from last year but the National Association of Realtors has also come out with their explanation of the process. Both of these will put most minds at ease.

Does Health Care Bill Contain 3.8% Home Sales Tax? from The KCM Crew:
We have received many questions about a possible 3.8% tax which will be put on home sales beginning in 2013. We want to do our best to clarify this situation for everyone. We are not accountants and give you this information just as a simple answer to the misconception. Understand that, when it comes to IRS regulations, you should check with your accountant for the most accurate and up-to-date information.
A little history on the confusion
Fact Check.org explains it this way:
The truth is that 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.
We can understand how this misconception got started. The law itself is couched in highly technical language that only a qualified tax expert can fully grasp. (This provision begins on page 33 of the reconciliation bill that was passed and signed into law.) And it does say the tax falls on “net gain … attributable to the disposition of property.” That would include the sale of a home. But the bill also says the tax falls only on that portion of any gain that is “taken into account in computing taxable income” under the existing tax code. And the fact is, the first $250,000 in profit on the sale of a primary residence (or $500,000 in the case of a married couple) is excluded from taxable income already. (That exclusion doesn’t apply to vacation homes or rental properties.)
The Joint Committee on Taxation, the group of nonpartisan tax experts that Congress relies on to analyze tax proposals, underscores this in a footnote on page 135 of its report on the bill. The note states: “Gross income does not include … excluded gain from the sale of a principal residence.”
And just to be sure, we checked with William Ahern, director of policy and communications for the nonprofit, pro-business Tax Foundation. “Some home sales would see a tax increase under this bill,” Ahern told us, “but it would have to be a second home or a principal residence generating [a gain of] more than $250,000 ($500,000 for a couple).”

Simple Explanation:
The following simple explanation comes from midiShaw:
The tax will affect those sellers of real property who will be otherwise taxed on capital gains under current tax laws. Under current laws, if you sell your primary residence and meet the ‘time ‘ criteria, you are exempt up to $250,000 or $500,000 (filing individually or jointly). Any amount realized OVER that amount is taxable under current tax schedules based on income. As such, this new tax will apparently be added to the current capital gains tax burden IF your income is over $200,000/$250,000 (filing individually or jointly). For those selling second homes and investment properties, the tax, once again, will be applied to the amount of gain realized.

Detailed Explanation:
The following also comes from midiShaw in a comment to the above answer.
Beginning in 2013, the national health care reform legislation that became law in March, 2010, imposes a new 3.8 percent tax on certain investment income. The new tax will apply to single filers with incomes over $200,000 and married taxpayers with incomes over $250,000. Under the law, the investment tax provisions in Chapter 2A of the Internal Revenue Code are placed under the heading “Unearned Income Medicare Contribution.” In general, this new Medicare tax will apply to investment income that is subject to income tax, which includes capital gains. Pursuant to IRC Section 1402 (C)(1)(A)(iii), the investment income to which this new tax applies includes “net gain” (to the extent taken into account in computing taxable income) attributed to the disposition of property that qualifies as a capital asset under Section 1221 (capital gains), as well as gains on other property that are considered part of ordinary income.
We offer this just as an explanation. Remember, when it comes to IRS regulations, you should check with your accountant for the most accurate and up-to-date information.
