U.S. citizens and resident aliens living outside the United States generally are allowed the same deductions as citizens and residents living in the United States. If you paid or accrued foreign taxes to a foreign country on foreign source income and are subject to U.S. tax on the same income, you may be able to take either a foreign tax credit on foreign income taxes or an itemized deduction for eligible foreign taxes. However, if you take the foreign earned income exclusion your foreign tax credit or deduction will be reduced.
If eligible, you can claim a foreign tax credit on foreign income taxes owed and paid by filing Form 1116 with your U.S. income tax return.
You may also be eligible for the foreign earned income exclusion. Please note that for purposes of the foreign earned income exclusion, the foreign housing exclusion, and the foreign housing deduction, foreign earned income does not include any amounts paid by the United States or any of its agencies to its employees. This includes amounts paid from both appropriated and non-appropriated funds.
