A number of foreign countries have tax treaties with the United States. Residents or citizens of the United States are taxed at a lower rate or are exempt from foreign taxes on certain items of income they receive from foreign nations under these treaties.
If the treaty does not cover a certain types of income, or if your nation and the US do not have a treaty, you must pay tax on the income. For more information, we recommend contacting a tax professional.
