W-8BEN

Form W-8BEN is an IRS document that a non-U.S. individual completes and provides to a U.S. payer to certify their foreign status and claim any applicable tax treaty benefits. Without it, the payer must withhold 30% of most U.S.-sourced income paid to the foreign individual, including dividends, interest, royalties, and service fees. A valid W-8BEN reduces or eliminates that withholding based on the individual's country of residence and any applicable tax treaty between that country and the United States.

Think of the W-8BEN as your proof of address for the IRS: it establishes that you live outside the U.S. and tells the payer exactly how much tax to withhold from your payments.

Who Needs to File a W-8BEN

Any non-U.S. individual who receives U.S.-sourced income needs to provide a W-8BEN to the withholding agent before the first payment is made. This includes foreign contractors paid by U.S. companies, foreign investors receiving dividends or interest from U.S. securities, foreign nationals with U.S. bank accounts or brokerage accounts, and foreign participants in U.S. partnerships.

Entities, meaning corporations, partnerships, and trusts, use a different form: Form W-8BEN-E. The W-8BEN itself covers only individuals. A sole proprietorship owned by a foreign individual uses the individual's W-8BEN, not the entity version.

The Three Parts of the Form

The W-8BEN has three substantive sections you complete.

• Part I (Identification): Your full legal name, country of citizenship, permanent residence address, and mailing address. If you have a U.S. Taxpayer Identification Number or foreign tax identifying number, you provide it here. Your date of birth is required when using the form for a U.S. financial account.
• Part II (Treaty Claim): Complete only if you are claiming a reduced withholding rate under a tax treaty. You identify your country of tax residence, the treaty article that applies, and the specific reduced rate you are claiming. You need a U.S. TIN or ITIN to process a treaty benefit claim.
• Part III (Certification): Your signature under penalties of perjury, certifying that all information is true and that you are the beneficial owner of the income. The withholding agent does not sign this form; you do.

The 30% Default Rate and What Treaties Change

The default U.S. withholding tax rate on payments to foreign persons is 30% under Chapter 3 of the Internal Revenue Code. Tax treaties negotiated between the U.S. and approximately 68 countries reduce this rate for specific income types. The U.S.-UK treaty, for example, reduces withholding on dividends to 15% or 5% for qualifying shareholders, and reduces withholding on royalties to 0% in most cases. The U.S.-Germany treaty eliminates withholding on interest entirely.

If the withholding agent relies on an expired or invalid W-8BEN and under-withholds, the liability for the shortfall falls on the withholding agent, not on you as the foreign payee.

Expiration and Renewal

A W-8BEN is generally valid for three calendar years from the date you sign it. A form signed on March 15, 2025 expires on December 31, 2028. If any information on the form changes before expiration, including your country of residence, your address, or your treaty claim, you must notify the withholding agent and provide an updated form within 30 days of the change. Becoming a U.S. citizen or resident also invalidates the form immediately.

W-8BEN vs. W-9

U.S. persons complete Form W-9, not W-8BEN. The W-9 provides your U.S. Taxpayer Identification Number and certifies that you are not subject to backup withholding. If a withholding agent asks you for either form, the correct answer depends entirely on whether you are a U.S. person for tax purposes. If you hold a green card or satisfy the substantial presence test based on your days in the U.S., you are a U.S. person and must complete a W-9.
