IRS 6166 Apostille | How to Obtain and Apostille IRS Form 6166

September 11, 2024 by Admin

Do you need to apostille IRS Form 6166?

Form 8802, the Application for United States Residency Certification, is used to request Form 6166, a certificate of residency. U.S. residents may need this form to claim benefits under income tax treaties and access certain other tax advantages in Hague Apostille countries.

Form 6166 is a letter printed on U.S. Department of Treasury stationary certifying that the company or person is a resident of the United States for purposes of income tax laws of the United States. You may use this form to claim income tax treaty benefits and certain other tax benefits in foreign countries.

To obtain IRS Form 6166, which is a “U.S. Residency Certification,” you need to follow these steps:

Complete Form 8802: You must file IRS Form 8802, “Application for United States Residency Certification.” This form requests the IRS to issue Form 6166.

Submit the Application:

  • Online: You can apply online through the IRS website. You will need to create an account if you don’t have one.
  • Mail: Alternatively, you can mail Form 8802 to the IRS at the address provided in the form instructions.

Pay the User Fee: A non-refundable user fee applies. The fee varies depending on the number of years for which certification is requested and whether you’re an individual or a business entity. Payment can be made via check or money order if filing by mail, or electronically if filing online.

Processing Time: Processing time can take up to 45 days. Ensure you submit the application well in advance of the date you need the certificate.

Receive Form 6166: Once the IRS processes your application and confirms your U.S. residency for tax purposes, they will send you Form 6166.  Please contact us once you receive this document.
