Complete form 1116 if the country you worked in has an agreement, or treaty, with the US regarding the tax treatment of your income. Under the "Income Resourced by Treaty" agreement, all of your income- foreign and US, is considered income form the treaty country when calculating the taxes you owe the foreign country.
You must figure a separate Form 1116 for each treaty country.
Within the program, the amount entered here will show on line 29 of Form 1116.
