What Is the W-9 Equivalent for Foreign Companies?

The W-9 equivalent for foreign companies is IRS Form W-8BEN-E. When a U.S. business asks a foreign entity for tax paperwork before releasing a payment, this is the form the entity provides. It certifies that the company is not a U.S. person, identifies its tax classification, and, where a treaty applies, claims a reduced rate of withholding. Without a valid W-8 on file, the U.S. payer is generally required to withhold 30% of the gross payment and send it to the IRS.

Which W-8 Form Applies to Your Situation

W-8BEN-E is the standard form for foreign corporations, partnerships, and trusts receiving U.S.-source income. It is not the only W-8, though, and using the wrong one gets the paperwork rejected.¹

Foreign individuals, including freelancers and sole proprietors without a separate legal entity, file W-8BEN, not W-8BEN-E.²
A foreign company earning income effectively connected with a U.S. trade or business files W-8ECI. That income is taxed at graduated rates rather than the flat 30%.³
Foreign governments, international organizations, foreign central banks, and foreign tax-exempt organizations file W-8EXP.⁴
Intermediaries and flow-through entities, such as a foreign partnership collecting income on behalf of its partners, file W-8IMY.¹

A foreign company with mixed income may need to give the payer both a W-8ECI for the U.S.-connected portion and a W-8BEN-E for the rest.³

How to Fill Out Form W-8BEN-E

The current version is the October 2021 revision on the IRS website. The form is long, but most foreign companies complete only a handful of sections. Before starting, pull the company’s legal name, country of incorporation, and permanent address from official corporate records so the entries match.

Part I: Entity Identification

Part I collects legal name, country of incorporation, permanent address, and the entity’s U.S. tax classification (corporation, partnership, trust, and so on). Line 5 asks for the “Chapter 4 status” under the Foreign Account Tax Compliance Act (FATCA), which places the entity within the international financial reporting framework — for example, as a financial institution, an active business, or a passive investment vehicle.⁵

Part II: Disregarded Entities and Branches

Part II applies only in narrow cases: a disregarded entity with its own Global Intermediary Identification Number, or a branch of a foreign financial institution in a country different from the institution’s home.² A foreign operating company receiving ordinary payments for goods or services can skip it.

Claiming a Tax Treaty Rate

Part III is where a foreign company claims a reduced withholding rate under a treaty between its home country and the United States. The default rate on most U.S.-source income, including dividends, interest, and royalties, is 30%.⁶ Many treaties cut that to 15%, 10%, 5%, or zero, depending on the type of income and the specific treaty.¹

To claim benefits, the company identifies the treaty country, cites the specific treaty article, and states the rate it believes applies. It must also certify that it is the beneficial owner of the income and meets the treaty’s limitation-on-benefits requirements.

Taxpayer Identification Number

A treaty claim generally requires either a U.S. Taxpayer Identification Number (such as an EIN) or a Foreign Taxpayer Identification Number issued by the home country. Providing an FTIN on Line 9b satisfies the requirement, so most foreign companies do not need to get a U.S. TIN just to claim a treaty rate. Limited exceptions exist; for instance, dividends and interest from actively traded securities do not require a TIN for treaty purposes.⁵ Missing or incorrect identification numbers are one of the most common reasons a W-8BEN-E gets rejected.

FATCA Status: Active Versus Passive NFFE

Foreign companies that are not banks or other financial institutions typically classify themselves as either an Active NFFE or a Passive NFFE. NFFE stands for Non-Financial Foreign Entity, and the choice determines what else the company has to disclose.

An entity qualifies as an Active NFFE if less than 50% of its prior-year gross income was passive (dividends, interest, rents, royalties, annuities, and similar items) and less than 50% of its assets produce passive income. Most operating businesses — manufacturers, service firms, retailers — meet this test.⁵

A Passive NFFE is any foreign non-financial entity that fails the active test. Passive NFFEs must disclose their substantial U.S. owners on the W-8BEN-E, a rule aimed at preventing U.S. taxpayers from parking assets behind foreign shell entities.⁵

The classification on Line 5 must match the corresponding certification part of the form: Part XXV for Active NFFE, Part XXVI for Passive NFFE. A wrong classification can trigger extra withholding or invalidate the form.

When U.S. Withholding May Not Apply

Not every payment to a foreign company is subject to withholding. The 30% rate reaches only U.S.-source income, and for services the source depends on where the work is performed, not where the check is mailed.⁷

A software firm in Berlin building an application entirely from its German office is earning foreign-source income, and no U.S. withholding applies to payment for that work. The U.S. payer may still ask for a W-8BEN-E for its records, but nothing gets held back. Dividends, interest, royalties, and rents tied to U.S. assets are U.S.-source income no matter where the foreign recipient sits.⁸

Where to Send It and How Long It Lasts

A completed W-8BEN-E goes to the withholding agent or financial institution making the payment. It is not filed with the IRS. The payer keeps it on file for its own records and any future IRS audit.

The form generally stays valid from the date of signing through the last day of the third full calendar year that follows. A form signed on March 15, 2026, remains valid through December 31, 2029.⁵ Under certain conditions, it can remain valid indefinitely as long as nothing on it becomes incorrect, though many withholding agents ask for renewals every three years regardless.

If anything on the form changes — address, tax classification, treaty eligibility — the company must notify the withholding agent and submit a new form within 30 days.⁹

Withholding agents can accept electronic signatures, but the IRS has conditions. The signature must include a time-and-date stamp and a statement that the form was electronically signed by an authorized person. Simply typing a name in the signature field is not enough, and the payer may ask for proof of the signer’s authority.⁵

What Happens If the Form Is Missing or Wrong

Without a valid W-8 on file, federal law requires the withholding agent to take 30% of the gross payment to a foreign corporation and send it to the IRS.⁶ This chapter 3 withholding is separate from the 24% backup withholding that applies to U.S. persons who fail to provide a W-9.⁸

The financial exposure sits on the U.S. payer. If the IRS finds that a payment went out to a foreign entity without proper documentation, the withholding agent can be held liable for the full 30%, plus interest and penalties.¹⁰ That is why most U.S. companies will not release a dollar until a correctly completed W-8BEN-E is in hand.
