Apostille IRS Form 6166

IRS Form 6166 ApostilleDo you need an Apostille on IRS Form 6166?

The United States has tax treaties with a number of foreign countries. Under these treaties, residents or citizens of the United States are taxed at a reduced rate, or are exempt from foreign taxes, on certain items of income they receive from sources within foreign countries.  The IRS Form 6166 is also referred to the U.S. residency certification.

If the treaty does not cover a particular kind of income, or if there is no treaty between your country and the United States, you must pay tax on the income.  We recommend that you contact an tax professional for more information.
