Apostille IRS Form 6166 – U.S. Residency

You are required to obtain your U.S. Residency form, or the IRS Form 6166, and you need it apostilled. First, let’s look at why you need this form and then how we can help you apostille the US Residency Form.

What is an IRS Form 6166 – U.S. Residency Form?

This form is printed on the U.S. Department of Treasury official stationery and certifies that, for federal tax purposes, an individual or company is a United States resident. Two reasons you may need it are:

  • It is submitted to a foreign withholding tax agent when the person or company wants to claim benefits under the tax treaty between the United States and another country.
  • It is also needed when a company or individual must obtain an exemption from a VAT (value-added tax) imposed by a foreign country.

The U.S. Residency form will also include the EIN (Employer Identification Number) of the business or SSN (Social Security Number) of the individual and the tax year for which the letter is issued.

To receive this, you must have filed the appropriate tax returns and are current on all taxes; plus, you must have not filed any forms in the US that shows you are a resident of another country.

How to Apostille U.S. Residency Form 6166

Before you can begin the apostille process for this form, you must have an original document; you cannot apostille a notarized copy of the U.S. Residency form
