Do you currently reside in the US? If not, what country do you reside in?
Is the home you are selling your primary residence?
As a US citizen, you are subject to tax on all of your income, regardless of the source. So if you have a home abroad that you are selling, you would be responsible for capital gains tax on any profit from the sale of that home. This would be reported on Schedule D under long term capital gains, assuming you have owned the home for more than one year.
You may, however, also receive a credit for any tax you had to pay to the foreign country where the home is located, assuming that a tax is due to that country when you sell the home.
