IRS Form W-8ECI is a Certificate of Foreign Person's Claim That Income Is Effectively Connected With the Conduct of a Trade or Business in the United States, effective 10/21. It confirms that income is connected to a U.S. trade or business and helps avoid withholding at the 30% rate.
Plain English
This form tells the IRS that foreign income you earn is linked to your work or business activities within the United States. By filing Form W-8ECI, you certify this connection so that the payer does not withhold taxes from your payments at the standard 30% rate. This applies especially when transferring interests in a life insurance contract.

⚠ If something goes wrong
This form tells the IRS that foreign income you earn is linked to your work or business activities within the United States. By filing Form W-8ECI, you certify this connection so that the payer does not withhold taxes from your payments at the standard 30% rate. This applies especially when transferring interests in a life insurance contract.
A foreign transferor who is a dealer in securities seeking to claim an exception from withholding on a PTP interest must provide Form W-8ECI. Additionally, a seller of a life insurance contract or an interest therein whose income is effectively connected with their U.S. trade or business must provide it.
Part I collects identifying information, including the filer's name and address, and specifies if the payment is from a U.S. branch. Part II requires certification under penalty of perjury regarding the income being effectively connected with a U.S. trade or business.
The form must generally be given to the withholding agent before the payment is made, credited, or allocated. For a foreign dealer claiming an exception from withholding on a PTP interest, this applies when making the certifications set forth on line 12.
Do not send Form W-8ECI directly to the IRS; instead, give it to the person requesting it (the payer). A separate Form W-8ECI must generally be given to each withholding agent.
First, complete Part I by entering your name and address details. If you are an individual, provide your U.S. TIN (SSN, EIN, or ITIN) on Line 7. Finally, sign the certification in Part II under penalties of perjury to validate the claims.
If you do not provide Form W-8ECI, the withholding agent must withhold at the 30% rate or the backup withholding rate. Failure to certify correctly can also mean income is not considered effectively connected with a U.S. trade or business.
Give it to the person requesting it (the withholding agent), not directly to the IRS. Ensure you provide it before payment/allocation.
