No. Foreign entities can use an Individual Taxpayer Identification Number (ITIN) or an Employer Identification Number (EIN) issued by the IRS.

The form is valid until the end of the third calendar year after the year it was signed, unless a change in circumstances makes the information incorrect.

Fillable Form W-8ECI – Claim Effectively Connected Income

The IRS Form W-8ECI (Certificate of Foreign Person’s Claim That Income Is Effectively Connected With the Conduct of a Trade or Business in the United States) is required when a foreign individual or entity receives income that is effectively connected (ECI) with a U.S. trade or business. Using a fillable PDF saves time, reduces errors, and lets you submit the form electronically.

What Is Form W-8ECI?

Form W-8ECI certifies that the income you receive is ECI and therefore subject to regular U.S. income tax withholding rather than the 30% flat rate applied to non‑effectively connected payments. The form also provides the IRS with your taxpayer identification number (TIN) and details about the trade or business activities.

When and Who Must Use Form W-8ECI

Foreign individuals, corporations, partnerships, or trusts earning ECI from U.S. sources.
Payments such as rents, royalties, interest, or services that are connected to a U.S. trade or business.
When you are not eligible to claim a chapter 3 or 4 exemption on Form W-8EXP.
