W-8BEN-E for Amazon: What a Korean Company Files

Which form a Korean company gives Amazon, when, and for how long

This post answers two questions:

"Amazon's page says W-8BEN. Is that the form for a company too?"

"Do we file it once, or every year?"

The short answer: a Korean company's form is the Form W-8BEN-E, not the W-8BEN, and Amazon's tax interview creates it. This post summarizes public IRS and Amazon guidance. It is not tax advice.

1. W-8BEN-E is the company form; W-8BEN is for individuals

The top of Form W-8BEN-E says it plainly: "For use by entities. Individuals must use Form W-8BEN." Both forms are certificates that a foreign person gives to a withholding agent. The IRS defines a withholding agent as any person, U.S. or foreign, that has control, receipt, custody, disposal, or payment of U.S. source FDAP income subject to chapter 3 or 4 withholding.

Form	Who uses it	IRS source
W-8BEN	Foreign individuals (nonresident aliens)	About Form W-8 BEN
W-8BEN-E	Foreign entities, such as a Korean company	About Form W-8 BEN-E

The confusion comes from Amazon's own wording. Amazon's United States Tax and Regulatory Considerations page says non-US taxpayers must provide "Form W-8BEN." The same page also says: "The responses you provide to the tax interview questions will create the appropriate tax form on your behalf."

You do not pick the form by name. Answer the interview as a company, and check that the form it creates is the W-8BEN-E.

2. When to give the form, and to whom

The IRS instructions for Form W-8BEN-E say to give the form "to the person requesting it before the payment is made to you, credited to your account, or allocated." They also say: "Do not send Form W-8BEN-E to the IRS."

On Amazon, you provide the form through the tax interview:

All selling partners must complete it, "regardless of the number of transactions they have in a calendar year" (Amazon FAQ).
Only the primary user of the Selling on Amazon payment account can open it (U.S. Tax Interview FAQ).
You can download an electronic copy at the end. Amazon sends no paper copy and asks you to keep one.

If you sign electronically, Amazon processes it faster. A mailed hard copy takes 10 to 15 business days to process after Amazon receives it.

Settle who the primary user is before the interview, since nobody else can open it.

3. The entries a Korean company should check

The line numbers below follow the IRS instructions for W-8BEN-E (Rev. October 2021).

Line 1, name. Amazon's interview FAQ says businesses should "use the name that appears on your income tax returns."
Line 2, country. For a corporation, this is the country of incorporation, so Korea.
Line 4, chapter 3 status. You check your classification "under U.S. tax principles (not under the law of a treaty country)." US regulations (26 CFR 301.7701-2) list the Korean Chusik Hoesa (주식회사) as a corporation.
Line 5, chapter 4 status. Required only in some cases, such as when you are the payee of a withholdable payment.
Lines 8 and 9b, tax ID. For a treaty claim, you give a US TIN on line 8, or the foreign TIN (FTIN) from your country of tax residence on line 9b. An EIN is the US TIN for entities; you apply for one on Form SS-4 when you need one.
Signature. An authorized representative or officer signs. An agent who signs needs a power of attorney attached.

The Korean FTIN and the chapter 4 status are questions for your tax professional.

Line 4 follows US tax classification, not the Korean company type on your registration.

4. Validity: through the end of the third year after signing

Per the IRS, a W-8BEN-E generally stays valid from the date it is signed until "the last day of the third succeeding calendar year." A form signed in 2026 is valid through December 31, 2029, unless information changes. Under certain conditions, a form stays in effect indefinitely absent a change of circumstances.

Two events call for a new form sooner:

A change in circumstances. You must notify the withholding agent within 30 days and give a new form when a certification becomes incorrect.
An Amazon prompt. "When prompted, foreign sellers are required to retake the tax interview to submit a new form."

To update the form, Amazon's help page lists Settings, Account Info, Tax Information, then Update Tax Information.

Put the expiry date on the calendar the day you sign.

5. What happens without a current form

The IRS instructions say that without the form, "the withholding agent may have to withhold at the 30% rate ..., backup withholding rate, or the rate applicable under section 1446." The 30% rate applies to US-source FDAP (fixed or determinable annual or periodical) income. The same instructions say amounts subject to chapter 3 withholding do not include "most gains from the sale of property." Whether your Amazon payouts fall under any of this is a call for your tax professional.

Amazon's rule is direct: "If you are a non-US person, failure to maintain a current Form W-8 will result in suspension of your selling privileges."

On Amazon, the stated result of no current Form W-8 is suspended selling privileges.

6. Treaty boxes and US warehouses: ask a tax professional

The US-Korea income tax convention was signed in Seoul on June 4, 1976 and entered into force on October 20, 1979. Under Article 8(1), a Korean resident's business profits are exempt from US tax unless it does business in the US through a permanent establishment (PE), a fixed place of business.

Article 9 covers US inventory:

Article 9(2) lists a warehouse as a fixed place of business.
Article 9(3) excludes a place used "only" for storage, display or delivery of the company's own goods, or for keeping a stock of them for those purposes.
Article 9(4)(b) treats a company as having a PE when it does business through an agent who keeps the company's stock in the US and regularly fills orders or makes deliveries from it.

Article 17 limits benefits under the dividend, interest, royalty and capital gains articles for some corporations: those with special tax measures and with 25% or more of their capital held by persons who are not individual residents of their home country (for a Korean company, also US citizens). Line 14b of the form asks about limitation on benefits.

Your line 14b box and PE status depend on your facts.

The treaty question is how you use a US warehouse, not only whether you have one.

Wrap-up

Under the IRS rule, a Korean company gives its W-8BEN-E before it is paid. Amazon's tax interview creates the form. The form generally expires on December 31 of the third succeeding calendar year after signing. Take the treaty and PE questions to a tax professional. See also our sales tax nexus guide. For where inventory sits, see Amazon FBA vs 3PL.

LinkONE handles Amazon US store setup for Korean brands, from seller account registration and listing optimization to inventory management and Amazon Ads.

In the end, the W-8BEN-E is not a one-time form. It is a record you keep matched to your company and renew before it expires.

Frequently Asked Questions

Does a Korean company file W-8BEN or W-8BEN-E for Amazon?

W-8BEN-E. The IRS form says: "For use by entities. Individuals must use Form W-8BEN." (Form W-8BEN-E). Amazon's US help page names only W-8BEN, but its tax interview creates the form from your answers.

When do I give Amazon the W-8BEN-E?

Before the payment is made, credited to your account, or allocated, to the party that requests it. Do not send it to the IRS (IRS instructions). On Amazon, every seller completes the tax interview.

How long is a W-8BEN-E valid?

Generally, until the last day of the third succeeding calendar year after signing. A form signed in 2026 is valid through December 31, 2029 (IRS instructions). If your information changes, notify the withholding agent within 30 days and submit a new form.

What happens if I do not provide a W-8BEN-E?

The IRS says the withholding agent may have to withhold at the 30% rate or the backup withholding rate (IRS instructions). Amazon says a non-US seller without a current Form W-8 has its selling privileges suspended (Amazon FAQ).

Does a US warehouse create a permanent establishment for a Korean company?

It depends on the facts, so check with a tax professional. Article 9 of the US-Korea treaty lists a warehouse as a fixed place of business but excludes a place used only for storage, display or delivery of the company's goods (US-Korea treaty).
