Since the Supreme Court passed “Obamacare” (i.e. the Affordable Health Care Act) earlier this year, I’ve been getting an unusual question from some fearful home sellers, “Will the passing of Obamacare force me to pay a new 3.8 percent tax on home sales beginning in 2013??”

I did the research and here is what you need to know home sellers - the majority of taxpayers will NOT have to pay it.

Which is totally true… except for the fact that it’s a total falsehood!

Dispelling Rumors

The rumors have long since been debunked, yet after the Supreme Court upheld the Affordable Health Care Act, I’ve once again heard some people once again pushing this narrative.

Added Capital Gains May Affect Some

Now there is an additional capital gains tax included in the Affordable Care Act, and yes it will affect a narrow field of real estate transactions. Here is how it breaks down:

The following explanation comes from our friends at 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.

Check out how Factcheck.org dispels this urban legend.

From Factcheck.org - ”The truth is only a tiny percentage of home sellers will pay the tax… 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).”

Remember I am not a tax expert. I’m just calling them like I see them. When it comes to IRS regulations, always check with your accountant or financial advisor for your tax information.
